TeXShop 4.15

TeXShop for Mac は、Mac OS X 用の TeX プレビューアで、Cocoa で書かれています。 pdf は OS X のネイティブファイルフォーマットなので、TeXShop はデフォルト設定で植字するために tex と latex ではなく pdftex と pdflatex を使います。 TeX の標準的な TeX Live ディストリビューションのこれらのプログラムは、dvi 出力の代わりに pdf 出力を生成します.

TeXShop は、Mac OS X、Windows、Linux、およびその他のさまざまな TeX Users Group(TUG)によって管理されている Tex プログラムの標準配布 TeX Live を使用します Unix マシン。この配布には、TeX、ラテックス、dvips、テックスフォント、キリル文字フォント、TeX の世界で一般的に使用されている他のプログラムやサポートファイルが含まれます。このディストリビューションの最新版は、TeX Users Group の MacTeX TeXnical Working Group によって Mac 用に管理され、「取得中」タブの下にあります。 TeXShop は GPL の公衆ライセンスの下で配布され、無料です。最新の TeXShop for Mac には、Mavericks、El Capitan、または Yosemite.

が必要です。Macintosh 上の標準 TeX ディストリビューションは TeX Live と呼ばれています。 BasicTeX は TeX Live の小さなサブセットですが、TeX について深刻な人は完全な配布を得るべきです。テックスユーザーグループ(TUG)の MacTeX ワーキンググループは、TeX Live と、Mac OS X 上で TeX を実行するために必要なものすべてをワンステップでインストールするインストールパッケージを構築しました。このパッケージは無料で、Apple の標準インストーラを使用しています。インストールには 4〜8 分かかり、自動的に行われます。このパッケージは、世界中の TeX ユーザグループが協力して作成した TeX の完全版である TeX Live をインストールします。また TeXShop を含む TeX のための Ghostscript といくつかの GUI ユーティリティをインストールするので、フロントエンドを別々に取得する必要はありません。それがインストールする GUI プログラムの 1 つは TeX Live を最新の状態に保つことができる TeX Live Utility です。インストーラが完了したら、すべてが完全に構成され、使用準備が整いました.

What's new in this version:

TeXShop 4.15
- In TeXShop 4.14, a file named TeXShop,scriptSuite and a program named ScriptRunner were inadvertently omitted from the TeXShop Application Bundle. This broke several Applescript macros. The missing files are again present in TeXShop 4.15

TeXShop 4.14

- In macOS Lion, Apple added a "bounce" when the text in Text Edit scrolled to the top or bottom of the screen. Some users found this bounce excessive, and we added two hidden Preference Items to control it. The first, "defaults write TeXShop SourceScrollElasticity NO" was supposed to turn this bounce off, but in succeeding versions of macOS had less and less effect. The bounce also caused line number scrolling to break near the top and bottom of the text, and we added an extra fix for this problem: "defaults write TeXShop FixLineNumberScroll YES". But future versions of macOS fixed this "Line Number Scroll Bug", so our fix wasn't necessary and instead caused harm by dramatically increasing the bounce effect
- In version 4.14 we have given up on bounces and disabled both of these hidden preference items. The result is a mild bounce similar to the behavior of scrolling in other text programs. For many of us, the change improves the behavior of scrolling near the top and bottom of the source in TeXShop
- In Dark Mode on Mojave, many symbols in the LaTeX Panel were barely visible. This is fixed
- The Sparkle Update Framework in TeXShop has been updated to the latest version. Sparkle updates are protected by a public key encryption system. Until this update, that public key was DSA, but Sparkle has switched to EdDSA, a system based on elliptic curves. This version of TeXShop contains both public keys so updates from older versions of TeXShop still work. Once you have TeXShop 4.14, further Sparkle updates will use the EdDSA key. For some time to come, TeXShop will contain both keys to protect users who are slow to update
- Latexmk has been updated to version 4.61
- The German translation of buttons in the log window is fixed
- The Sage engine documentation in TeXShop/Engines/Inactive has been updated for the current version of Sage
- For a number of years, TeXShop has been signed using my Apple Developer ID. This protects users who download the program from the internet and have the default Apple security system enabled. The first time they run TeXShop, a dialog appears saying "TeXShop is an app downloaded from the internet. Are you sure you want to open it?" If we didn't sign the program, this dialog would instead report that it was from an unknown developer and should be thrown into the trash
- Starting next year, Apple will require two additional steps from developers. First, they will require that programs be compiled with a "Hardened Runtime." This is a system in which programs indicate that they intend to use facilities which could compromise security: camera, location services, address book, photo library, execution of JIT-compiled code, etc. Version 4.14 was compiled with the hardened runtime turned on, but did not have to turn on any of these exceptions. Note that a Hardened Runtime is NOT a sandboxed application. Sandboxing, which is required for applications in the App Store, could seriously affect TeXShop's interaction with the command line programs in TeX Live, so I have never even investigated sandboxing the program or adding it to the store
- The second additional step is to send the program to Apple before signing so they can "machine check" it for viruses and other security flaws. At the 2018 Developer Conference, Apple strongly emphasized that this was not a code review or interface validation, but just an additional check for security problems. The check takes from five to ten minutes and requires a hardened runtime in advance
- The two steps are optional this year, but become mandatory next year. TeXShop 4.14 passed both steps. According to the Developer Conference, there is a way for users to detect this: in the dialog that appears when TeXShop is first opened, the TeXShop icon should appear rather than just a generic icon

TeXShop 4.13

- The Apple Color Picker has many ways to select a color: by mousing in a color wheel, by using RMK and CMYK sliders, by selecting crayons, and by directly entering color values in a box. This final method caused the Picker to close in 4.** versions of TeXShop. This is fixed
- In TeXShop Preferences under the Editor tab, in the second column, there is an item called "Flash Back for Isolated Parens". When selected, this item causes TeXShop to flash a slightly pink background color on the screen when a bracket or parenthesis with no matching symbol is typed, and then return to the original background color. On Mojave, the screen always returned to a white background, even in dark mode. Moreover, there was no way to change the "pink" color in the Themes editor. This is fixed. Now the command works in both Lite and Dark modes, and the "Flash" color for the Editor can be changed in the Themes tab
- Applescript macros in TeXShop can run in two ways. If the macro begins with the phrase "-- applescript", a separate small program, ScriptRunner, embedded in TeXShop runs the macro. If the macro begins with the phrase "-- applescript direct", TeXShop itself runs the macro. Herbert Schulz pointed out that ScriptRunner code has not been modified in several years and still contains both 32 bit and 64 bit code. This is fixed
- Version 4.08 introduced a new preference "Remaining Lines Paragraph Indent" under the Editing tab. By default, this value was set to 30, which caused TeXShop to format paragraphs of source code by indenting all lines after the first line. I received more mail about this than any other change in the 4.** series, and I learned an important lesson: "When a new feature is introduced which will change the appearance of the source code, the default value should make no change!" In version 4.13, the default value of this item is 0. Users who installed earlier versions and have been living with an 'undesirable feature' will need to change the default manually

TeXShop 4.12
- Many TeXShop macros stopped worked on Mojave. These macros use AppleTalk and AppleEvents to communicate with other programs. Apple has sandboxed AppleEvents in Mojave for security reasons. Now before such interaction is allowed, a dialog appears explaining what is about to happen, and giving the user the opportunity to allow or forbid the interaction. This dialog contains the line "TeXShop uses Apple Events to process AppleTalk scripts in the Macro Editor". This line is defined in a new element in the Info.plist file, which was absent in earlier versions of TeXShop, is present in version 4.12, and is required before sandboxed AppleEvents can be sent
- Two users have pointed out that the preference item "Flash Back for Isolated Parens", in the second column under the Editor tab of TeXShop Preferences, breaks Dark Mode. Users of Dark Mode should turn this item off

TeXShop 4.10
- When a blank new document was opened in 4.08 and 4.09, the text was colored black regardless of the chosen Theme. This is fixed
- Previously, {, }, and $ were syntax colored, but [, ] were not. Now all of these symbols receive the same syntax coloring
- TeXShop gives a Command Color to symbols beginning with / and continuing with 'a' - 'z' or 'A' - 'Z'. These are the typical commands used by Latex authors

TeXShop 4.09
- This version fixes a bug in the Theme Preference code of TeXShop 4.08. Apple's color picker has several modes, including options to choose colors using CMYK values or gray scale sliders. In version 4.08, TeXShop obtained colors from color wells, and asked these colors for their RGB values without first converting colors in other color spaces to RGB

TeXShop 4.08

- When previous versions of TeXShop ran on Mojave, several tools in the Source and Preview toolbars were missing. These items could be restored using several tricks, including opening the "Customize Toolbar" dialog. But they would again be missing the next time TeXShop ran
- This bug is fixed in version 4.08. But users who ran an earlier TeXShop on Mojave will have to take one of two actions to restore their tools. The safest is to open a project which has both a source window and a preview window, With the source window active, select the Windows menu item "Customize Toolbar..." and drag the custom set of tools to the toolbar. Repeat this operation with the preview window active. Then with the source window active, select the Windows menu item "Use One Window." Both source and preview will appear in a single window. With this window active, select the Windows menu "Customize Toolbar..." and drag the custom tools to the single-window toolbar
- Another more drastic way to fix the problem is to make sure TeXShop is not running and throw away ~/Library/Preferences/TeXShop.plist. Then run TeXShop. Tools will reappear. Reset any preference item you may have changed
- When line numbers were showing on the Source Window in Mojave, the source could scroll by about half an inch in the horizontal direction. Scrolling to the left made the beginnings of line vanish under the line numbers column. Scrolling to the right made half an inch of the source vanish off the right side. This turned out to be a Mojave bug, which Apple fixed in the fifth developer beta
- Programs must be recompiled on Mojave before they support Dark Mode on that system. When TeXShop was recompiled, the magnifying glass broke, the fix for a "flash after typesetting" broke, and two other features broke. All depended on drawing into an invisible overlay view above the Preview Window. This drawing code has been revised to work on Mojave, and the revised code also works on earlier systems
- On Mojave, the "General" preference pane for Apple's System Preferences has the ability to switch between "Light" and "Dark" appearances of the interface. In Dark mode, the toolbars of windows have a dark background, Preference and Print panels have a dark background, and so forth. But Dark Mode does not change the content regions of program displays. So in initial Mojave betas, the TeXShop editor still had black text on a white background, and the TeXShop Preview window still had the standard appearance of typeset output
- Some Apple programs on Mojave change these content regions in Dark Mode and others do not. For instance, Apple's TextEdit shows black text on a white background, but the editor in XCode switches to white text on a dark background. Apple's Preview program continues to show pdf files with their standard appearance, including black text on a white background. This is not surprising since the alternative would be to reach into the pdf file and switch colors on the fly, a more or less hopeless task
- So the question is, what should TeXShop do in Dark Mode? Note that TeXShop has had the ability for many years to change text color and background color in the Editor, the Console, and the Log file. TeX pdf output contains black text on a transparent background, so the underlying paper color shines through when printed. Thus the color of the Preview window can be changed by changing the background color of that window, an ability that has been in TeXShop for some time
- In this version of TeXShop, we allow users to design their own "Dark Mode" for content regions. By default, the editor switches to white text on a black background in Dark Mode, and the Preview window receives a darker glow in that mode. But users can decide to keep the original black on white appearance of these content regions, or design their own color theme
- To make this work, the Preference Panel's color choices have been completely rewritten. There is now a tab called "Themes" devoted to coloring various components of the program. All of the color commands have been moved to this tab. These new color commands work on all systems supported by the program, not just on Mojave. In previous versions of TeXShop, many colors could only be changed using various obscure hidden Preference settings. Now all color choices are available in the Themes tab
- The Themes portion of Preferences is shown above. On the right are all colors currently set by TeXShop. Some items have an obvious meaning and others are obscure. A full set of such choices is called a "Theme". TeXShop allows users to create as many themes as they like. These themes are listed in three pulldown menus on the left: Lite Mode Theme, Dark Mode Them, Theme to Edit. The first menu sets the theme used on all systems below Mojave, and the theme used in Lite Mode on Mojave. The second menu sets the theme used in Dark Mode on Mojave. The final menu sets the theme which Preferences is currently editing
- TeXShop is shipped with several themes, including "LiteTheme" and "DarkTheme". These are the default themes for Lite Mode and Dark Mode. As explained later, there is a way for users to rename or remove Themes known to TeXShop. But TeXShop will always replace "LiteTheme" and "DarkTheme" and use them if other required themes are missing
- Gary Gray contributed two themes, GLG-Lite for Lite mode and GLG-Dark for Dark mode. Gray then tweaked GLG-Dark, and ended up with a dark theme that was was so my better than mine that I ended up using it as the default and thus renaming it DarkTheme. So Gray lost credit, but gained users. Thanks
- Two other themes, SolarizedLite and SolarizedDark, appeared first on the internet before Mojave was introduced. The general page by Ethan Schoonover about this design is https://ethanschoonover.com/solarized/. Specific lite and dark designs were then created in 2012 by "johannesjh": https://github.com/altercation/solarized/issues/167
- A final theme, which I call Manteuffel, was created in 2016 by Christian Manteuffel based on the design of iA Writer. See http://christian.manteuffel.info/blog/ia-writer-inspired-theme-for-texshop
- There is no distinction between themes for Lite Mode and themes for Dark Mode. Thus both Lite Mode Theme and Dark Mode Theme could be set to LiteTheme if the user always wants dark text on a white background
- After editing a theme, push "Cancel" or "OK" to end a preference session. If "Cancel" is pressed, the edited colors will not be saved and the Lite Mode and Dark Mode themes will return to choices before opening the Preference Pane. If "OK" is pressed, the edited colors will be saved and Lite Mode and Dark Mode themes will change to their new values
- But some users may want to edit several different themes during a session. When these users are finished editing their first theme, they should press "Save Edited Theme." This will save the changes for that theme permanently, even if the entire session is ended using the "Cancel" button. Repeat the process for other themes
- To create a new theme, first change "Theme to Edit" to obtain reasonable starting colors for your new theme. Then push "Create New Theme" and fill in the resulting dialog with a title for this threme. Do not use spaces in this title. The new theme will become the "Theme to Edit" and you can begin changing colors
- You may have set color preferences for TeXShop in previous versions of the program. These color preferences still exist, but they are no longer used by the program. To create a theme using these old preference settings, push "New Theme from Prefs". You'll be asked to name the theme; please do not use spaces in this name
- Some people on the internet developed color themes for TeXShop and made them available as shell scripts which reset various TeXShop color setting preferences. These shell scripts still work, but they no longer affect the appearance of TeXShop. After running such a script, you can use "New Theme from Prefs" to convert the "preference color scheme" to a regular Theme
- Recall that various TeXShop items which users can customize are set in ~/Library/TeXShop where Library is the Library folder in your home directory. This folder is often hidden in the Finder, but TeXShop has a menu item "Open ~/Library/TeXShop" to take you there. This folder has various subfolders. For example, one of the folders is named Templates. This folder contains the templates that appear in the Templates toolbar item. Each is an ordinary TeX source file. Adding new files to this Templates folder automatically creates new templates
- There is a new folder in ~/Library/TeXShop named "Themes". This folder contains very small ".plist" files describing the various Themes in TeXShop. If you create a theme you like, give it to others by putting its plist file on the Internet. To install a new theme of this kind, just drop its plist form in the Themes folder
- You can also remove Themes you no longer use by removing their plist files from the Themes folder. Avoid removing themes being used for Lite Mode or Dark Mode (although TeXShop should react gracefully when it runs into this situation). As explained earlier, the themes LiteTheme and DarkTheme will be recreated if they are removed
- When a theme is selected for editing, TeXShop colors will temporarily be reset to those colors. Revising colors is then interactive; as soon as colors change in Preferences, they will also change in TeXShop's Source and Preview windows
- Most colors at the top of the Preferences dialog are self explanatory. The colors "Invisible Chars, Enclosed Chars, Braces" are used for some features introduced by Yusuke Terada; see the menu item "Show Invisible Characters" and the item "Parens Targets & Highlight Color" in the Source Tab of Preferences, and the items "Show Invisible Characters" and "Parens Matching Settings" in the Editor Tab of Preferences. The items "Image Copy Foreground, Background" refer to features set in the Copy Tab of Preferences
- Finally, notice that the transparency of the Source, Preview, and Console windows can be set. These settings bring up a full Color Well, but the colors of these items are ignored and only the alpha values of the choices matter. Here "alpha = 1" is the usual value, and smaller values of alpha make the window more transparent

There are additional features of TeXShop 4.08 that are not related to Mojave:
- The first of these features comes from a bug report by Geoff Pointer. In TeXShop, double clicking on one of {, }, [, ], (, ), or finds the matching symbol and highlights everything in the source between these symbols. Pointer complained that this procedure ignored comments and escaped symbols, so double clicking } might well select a matching { in code that had been commented out, or a match of the form {
- These problems are fixed in version 4.08. When selecting a matching symbol, comments and escaped symbols are ignored. And by the way, TeXShop understands that % does not begin a comment
- TeXShop has another series of methods to deal with such brackets, added to the program by Terada Yusuda. These methods provide immediate feedback as the user is typing. One item flashes the matching bracket as soon as a bracket is typed; another temporarily highlights the region between matching brackets. One item momentarily flashes the screen if an unmatched bracket is typed. Some users depend on these features, while others find them distracting, so each feature can be turned on or off by preference settings at the top of the right column under the TeXShop Preferences "Editor" tab
- The bug reported by Geoff Pointer also applies to these second methods, and has not been fixed there. Because these methods are applied in real time during typing, and because they are used in small regions where the user is actively working, efficiency of code seemed more important than global accuracy. At a later time, this decision may be revisited
- The second of these features was requested by Brian Levine. If text is selected in the TeXShop editor and the selection is longer than two characters, then pressing (, {, (, or $ will enclose the selection in the appropriate brackets. This new behavior can be turned off in TeXShop Preferences by unchecking the item "Editor Can Add Brackets" under the Editor Tab
- The third feature was requested by Stephen Moye. The print dialog now contains an item to set paper size. Moye works with the AMS using a printer with trays for various paper sizes. Previously he had to select the paper size using "Page Setup" before dealing with the Print Dialog and printing. Now only one dialog is involved instead of two
- When Moye initially requested this feature, I told him that printing is controlled entirely by the underlying Cocoa system, so it would be impossible to fulfill his request. This proved to be not entirely true. Hence the new feature
- I'd like to use this occasion for a short aside. This aside may read like a rant about printers, but in fact its purpose is to explain why application programmers shouldn't have to deal with features of particular printers
- For years I've used a $1000 Color Laserprinter weighing 60 pounds. Recently a gear broke on the printer. It would be easy to fix it except that I couldn't figure out how to get the printer down my stairs and into the car. So I decided to buy a new printer and discovered that Laserprinters now cost $400. The store I visited delivers to the doorstep. But they absolutely, positively refused to deliver on up my stairs, or remove my old printer
- I asked the service representative what printer he'd recommend. He recommended a $79 HP. This seemed to me like a sort of "bait and switch in reverse," but I had to print, so I bought the $79 machine
- It prints faster than my old printer. The ink doesn't smudge. It has built in internet and was immediately recognized by all my devices. It calls home when it runs out of ink and new ink is delivered to my door, but so far it ran out of ink only once. It scans. It's light and was easy to carry up stairs. Apparently I was years and years out of date regarding printers, and I have to apologize to all my friends who asked for advice on buying one. (Remember, however, that I printed often when I was teaching, and I print rarely after retiring.
- What has this got to do with TeXShop? Well, TeXShop has essentially no code for handling printers. All of the messy details are handled automatically by Cocoa, Apple, and the printer manufacturers. Imagine what life would be like if programmers had to be involved in that chain. How many printers could we support even if we wanted to
- There are three main interaction points between users and printers. First, printers have their own preference module in Apple's System Preferences where the default page size can be set. This makes sense for most printers, whose paper trays can be configured to hold paper of different sizes, but only one size at a time. Second, the paper size of printers can be changed in "Page Setup", a menu item in TeXShop and most Cocoa programs. And finally, the print dialog handles all sorts of choices, like saving to pdf rather than printing, or many other things
- What is the point of Page Setup? Why is paper size set there? Because many programs use that knowledge to reset the behavior of the program. Should my editor for personal letters be formatted for letter paper? or a4 paper? Aha, Page Setup to the rescue
- However, in TeX, paper size is set by commands in the TeX source or configuration of the entire TeX Distribution. It would make no sense for TeXShop to reach into these sources and change them when Page Setup indicates a new paper size. So the truth is that TeXShop doesn't do anything when the user changes Page Setup. That menu is useless, particularly now that paper size is in the Print Dialog. But I'm keeping it, because otherwise I'd have to answer email questions of the form "where is page setup?
- In recent versions of TeXShop, the syntax coloring code is turning off while the source file loads. Therefore, files aren't syntax colored until the user begins moving the mouse. It is possible that this code was added to fix bugs if syntax coloring is started too soon, but experiments suggest that the bug no longer exists. So in version 4.08, files are syntax colored as soon as they are opened. In case of trouble, it is possible to return to the old behavior using a hidden preferenc
- Gary Gray requested that TeXShop start paragraphs flush with the left margin, but indent remaining paragraph lines. TeXShop 4.08 has this feature. Some users are in the habit of inserting line feeds when their source lines approach the right margin; they will not notice any difference. Other users type several lines of source text between line feeds. The resulting "paragraphs" will now be visible for easier scanning
- This feature is controlled by two new preference settings, available under the Edit Tab. The first sets the indent of the initial paragraph line. By default this is set to 0.0. The second sets the indent of the remaining paragraph lines. By default this is set to 30.0
- The item to set the length of tabs has been grouped together with the two above preference settings. Moreover, one more setting, previously hidden, is available. This setting changes the interline spacing between lines of the source. In particular, users can double space the source text if they desire by changing this value
- The tab length is an integer, and roughly measures the number of letters between tab settings. Thus small values of this setting are reasonable. The entry works even if the edit font is not monospaced
- But the remaining entries for First Line Paragraph Indent, Remaining Lines Paragraph Indent, and Interline Spacing are floating point numbers measured in points in user coordinates. Only limited ranges of these preference settings are allowed, and the Preference dialog will replace unreasonably large or small values by more reasonable maximum and minimum values
- TeXShop has a preference to select the desired dictionary used by the program. Thus the system wide dictionary can be a standard Apple dictionary, while TeXShop can be configured to use a cocoAspell dictionary which does not count LaTeX commands as misspelled. During the course of preparing TeXShop 4.08, we discovered that this Preference item was disconnected in most localizations. This is fixed. If the setting seemed to affect nothing earlier, please try again
- Items in the Templates pull-down menu in the toolbar used to be listed sorted alphabetically. Later, this menu was extended to allow sub-menus, and the sorting feature was lost. It is restored in 4.08
- Another request from Stephen Moye is to add a preference item forcing TeXShop to place the source window in front of the preview window when opening files. (There is already a preference which causes TeXShop to activate the source window after each typesetting job.) A hidden preference item has been created to do thi
- Many programs on the Mac access the internet. Apple recently required that programs use the https protocol rather than http for this access, due to the added security of https. But programs can opt out of that requirement. TeXShop directly accesses the internet in only two places (although it can use iCloud indirectly via Cocoa): it uses Sparkle for program updates, and it downloads two small movies if the user doesn't have them and asks to see them in TeXShop Help. Because faculty web pages at the University of Oregon were served with http, TeXShop opted out
- But the University of Oregon recently switched to https for faculty pages, so Sparkle and movie downloads have been switched to https and TeXShop no longer opts out of this security requirement
- Latexmk has been updated to version 4.60
- The "About" panel has a line giving a range of copyright dates. The range ended in 2017 because I failed to notice that that line was localized. Now it correctly ends in 2018
- Scrolling in the editor window has a "bounce" near the top. We added a hidden preference setting to remove that bounc
- Herbert Schulz revised the "File Encoding.pdf" file in the TeXShop Help menu
- The Help document "Comment Lines and Hidden Preferences" was revised to remove misprints pointed out by Herbert Schulz. Unfortunately, the document hasn't yet been extended with new information
- When TeXShop toolbars showed Text, or both Icons and Text, the Text was broken in many localizations. That was because I did not realize that XCode could set the encoding of the localization files ToolbarItems.strings. The encodings of these files are now all set to UTF-8 Unicode, and Text in the Toolbars finally looks reasonable
- The author of the Spanish localization, Juan Luis Verona, pointed out an important consequence of changing the default encoding in TeXShop to UTF-8. Characters with accents and umlauts can be encoded in Unicode either as special characters, or as combinations of characters. For instance, ü can be encoded as U+00FC or as U+0075 and U+0308. When a LaTeX or pdfLaTeX file is encoded in UTF-8, the typesetting engine calls usepackage[utf8]{inputenc} to interprete the input file. But this package does not understand combination characters. For an explanation of the reason these characters are hard to read, see https://tex.stackexchange.com/questions/94418/os-x-umlauts-in-utf8-nfd-yield-package-inputenc-error-unicode-char-u8̈-not/94420#94420
- Luckily, source characters with accents and umlauts typed by the user are encoded as single characters in TeXShop. But if a user copies the text from a pdf and pastes it into the source, combination characters are used. These look fine in TeXShop, but typeset incorrectly because of the inputenc problem discussed above. Incidentally, this problem does not occur when using XeLaTeX or LuaLaTeX
- This problem appeared much earlier in Japan, and Yusuke Terada added code to fix the problem. This code is turned on by an item in TeXShop Preferences under the Misc tab. The item used to read "During File Save (for Japan), Automatic UTF-8-Mac to UTF-8 Conversion". In version 4.08 of TeXShop, the words "for Japan" have been removed from this item, but it is still off by default. Users who run into the problem should turn it on. A little caution is required here; for instance, the item caused trouble for users writing in Hebrew (which is why we added the words "for Japan")
- In 2005 Michael Witten, then at M.I.T., added a "Wrap Lines" menu item to TeXShop. This menu offered to wrap lines "never", or "by word", or "by character". Witten added a hidden preference to set the default setting, and this preference is now made public in the Editor tab of TeXShop Preferences
- Most users are likely to stick with the default setting, "by word". I've added the setting because I wanted to write a little essay about line feeds
- In TeX, two line feeds produce a new paragraph; but TeX ignores single line feeds in almost all cases. Exceptions include comments, where adding a line feed in the middle adds the last half of the comment to the active text, and displayed formulas, which often break when line feeds occur in the middle. But otherwise, line feeds are irrelevant
- Thus a TeX paragraph can be written as one long line, or as several sentences, or as several lines broken in the middle. The style users adopt can depend on their background. Writers like to write paragraphs unbroken by line feeds. Programmers, however, tend to add line feeds after each sentence because when they are writing programs rather than TeX, these line feeds show the logical structure of the text. As an extreme example, in Apple's programming language Swift, individual statements need not end with a semicolon if they end with a line feed, so semicolons are only needed when stringing several statements together on a single line
- There are several advantages to writing TeX source as a series of lines, rather than as full paragraphs. Errors in TeX are indicated by line, so they can be found more rapidly when the source is a series of lines. Synctex also works by line and can produce more accurate syncs when lines are used
- Of course some programming languages ignore line feeds, and make it possible to write programs as long multi-command paragraphs, but such paragraphs are virtually impossible to read and programmers avoid them religiously
- Since programs are in practice a series of fairly short lines, programmers have many useful utilities built on the premise that they will deal with files containing short lines. One example is "diff", which can compare two files and clearly list the differences. This utility works well on TeX files written as a series of lines, but becomes more or less useless if the paragraph style is adopted. When programmers moonlight as editors of journal articles and the like, they can become frustrated when their favorite tools no longer apply
- All of this is to suggest to new users that it could be handy to adopt the style of adding line feeds to keep individual lines short. But the advantages are relatively minor and seasoned users have more important things to worry about
- Why is this issue related to TeXShop? The first key point to understand is that TeXShop never adds line feeds to a source file behind the user's back. Any line feed in a source file is present because the user pushed RETURN
- But what should happen if the user is typing and reaches the right side of the window? By default, TeXShop adds a "soft line feed" so additional characters appear on the next line. A "soft line feed" is a line feed that affects the appearance of the text, but is not added to the source file. There are several indications that such line feeds are soft. Resize the window, and notice that the text is reformatted and line feeds appear at different places. But the source doesn't change in any way. This is actually an advantage, because users can resize windows on the fly, and because when a source is moved to a new larger screen, the full window is used rather than ending up with blank space on the right
- In addition, such soft wraps are indicated in the line number column on the left of the window. The first line of a paragraph receives a line number, but if there are additional lines created by soft wraps rather than line feeds in the source, these lines have no line number because they are part of the line started above
- Some programmers, however, intensely dislike soft wraps because they destroy the logical appearance of the source which the programmer has carefully created. These programmers prefer no wrapping by the editor. When the user reaches the right boundary of the text, the editor should begin horizontal scrolling so additional characters are shown on the same line. The disadvantage is that users must scroll the text horizontally to read everything (or make the window wider if the screen has room). The advantage is that the logical structure is visible
- Programmers who work as editors of TeX articles may prefer no wrapping by the editor for another reason: it encourages authors to add those hard RETURN line feeds to the text and thus create source which is a series of fairly short lines. Thus the "Wrap Lines: Never" preference could be thought of as training wheels for the user
- That's my little essay. Adopt the editor behavior which makes you most confortable. Even if you stick with "Wrap Lines: by Word", you might like to get in the habit of adding more hard line feeds to the source
- Final question: why would anyone ever want to "Wrap Lines: by Character"? I have no idea. It is one of the options Apple provides, so it is an option Michael Witten provided, and therefore it is in Preferences
- Final observation: adding this Preference gave me a chance to look closely at Michael Witten's code from so long ago. He did not pick an easy programming task. Witten had to deal with the editor, and the scroll bar, and the layout manager, and "paragraph attributes", and lots of other things. In the end, I'm impressed that it all worked

TeXShop 4.01
- Daniel Nowacki discovered that in some circumstances, most file menus could be disabled in Single Window Mode. This included Show Console, Show Log File, Close, Save, Print, Print Source, Convert Tiff, Abort Typesetting, and Trash AUX Files. The problem is fixed
- Other items in this menu are deliberately disabled in Single Window mode, like Duplicate, Rename, Move To, Revert To, and Page Setup. It is easy to work around these. But Daniel's expanded list was a real nuisance

TeXShop 4.00
- Latexmk updated to version 3.55d
- The change in version 3.98 to set interline spacing and kerning in TeXShop Preferences was hopelessly broken. This was pointed out to me in a phone call from Louis M. Guenin. The method seemed to work, but any lines added later in the editor reverted to the original style. Consequently, this method has been disabled in 4.00. It is still possible to set interline spacing and kerning for individual files as in 3.98, but Preferences cannot set default values. The Preferences code is still in place and correctly sets font and font size. It also appears to set interline spacing and kerning, but when the user clicks "OK", those settings are ignored

TeXShop 3.99
- The German localization was updated
- The original Preference dialog did not fit on the screen when users had an 11 inch or 13 inch portable. In version 3.99 of TeXShop, an additional Editor tab was added to the dialog and the Source items were split between the Source and Editor tabs. This allows the entire dialog to be shortened
- When TeXShop opens a postscript file, it runs a script which calls ghostscript to convert the ps file to pdf, and then displays the pdf file. Bruno Voisin noticed that this process fails when the name of the postscript file contains spaces. He discovered the cause: the ps2pdfwrap script in TeXShop defining the conversion does not quote one filename. This is fixed.

TeXShop 3.98
- Early versions of High Sierra contained a bug which broke updating the Page Number box in the preview window during scrolling. The bug also broke the up and down arrows in the preview toolbar. This High Sierra bug is fixed in High Sierra 10.13.4, currently in beta release for developers. TeXShop 3.91 contains a workaround for the bug. The workaround runs a small routine to update the Page Number box once a second whenever the Preview Window is active, even when the user is not scrolling. In TeXShop 3.98, the workaround only runs on early versions of High Sierra, and the original more efficient TeXShop code runs on High Sierra 10.13.4 and above.
- Latexmk is updared to version 3.44a.
- Version 3.94 of TeXShop contained a fix for the "flash after typesetting" bug in High Sierra when the preview window is using multipage or double multipage modes. However, the fix was also applied in single page or double page modes, where is may have caused problems. In addition, the patch caused problems for some users who worked with an external editor, or turned on the "Automatic Preview Update" TeXShop preference. The patch has been reworked slightly to avoid all of these problems.
- The Font submenu in the Source menu has been enlarged with additional items from Apple allowing users to set interline spacing for the source text, and adjust the kerning and ligatures for this text. Keyboard shortcuts for interline spacing make it easy to adjust this spacing; for instance, double spaced source is possible. Additional items allow copying and pasting this style information, so once one source window has been adjusted, the adjustments can easily be applied to other source windows.
- The TeXShop Preference item to set the font for TeX source has been changed to also set interline spacing, kerning, and ligatures. Thus the style changes introduced above can be made default styles for all future files. This works as follows: clicking the Set button to initiate a font change makes a small sample window drop down to show the effect of Font and Style changes. The Font submenu in the Source menu is active for this small window, allowing Style changes as above. When the OK button for the sample window is pressed, these changes appear in all open TeXShop windows. The main Cancel or OK buttons in the Preference Dialog must still be pressed, either to retreat to previous choices for fonts and styles, or to make the changes permanent. The code to set default font styles has one minor bug I haven't been able to fix. If an empty window is opened, the font is correctly set for the window, but new font styles are not set. For example, suppose a user has requested double spaced source in TeXShop. If this user selects ``New'' to open an empty window and then selects the LaTeX Template, the new source in the window will be single spaced. It is easy to work around this bug. If the window is saved, closed, and reopened, the styles will ``take'' and the source will now be double spaced. Or if another window is open with correct spacing, the font style can be copied from this window and pasted into the new window.
- Following a suggestion by Emerson Mello, who provides the TeXShop localization for Brazil, an additional item has been added to the TeXShop Help menu. This item lists all "special comment" lines understood by TeXShop, and lists all hidden Preference items which can be set for the program. The special comment list is complete, but in this version of TeXShop, only some hidden preference items are listed. The list will be completed in future TeXShop versions.

TeXShop 3.97
- TeXShop 3.97 has a new preference setting determining whether the source editor is placed on the left or right side in Single Page mode
- Because work on MacTeX-2018 is beginning, TeXShop will not be further updated for several months

TeXShop 3.96
- For some time, TeXShop has had the ability to combine the source and preview windows of a document into a single window showing both views, or break such a window back into two windows. This is done with the commands "Use One Window" and "Use Separate Windows" in the Window menu. There is now a preference item in TeXShop Preferences to determine the mode used when a document is first opened. See the bottom of the Source tab in TeXShop Preferences
- The Sparkle update code in TeXShop 3.96 was updated to version 1.18.1
- In High Sierra when previewing in "multipage mode", each typesetting job caused a flash in the Preview window before new material appeared. This problem was fixed in versions 3.94 and 3.95. The fix worked by placing a picture of the old preview pdf over the Preview window just before switching to the new version of this pdf. The flash still occurred, but was hidden by the picture. One second later, the picture was removed, revealing the new pdf. The steps of placing a picture and later removing it were totally invisible to the user
- Because of a High Sierra bug, scrolling the Preview window did not update the Page Number box in the Preview toolbar. TeXShop 3.92 contained a workaround for this bug, but the workaround did not apply when the source and preview were contained in a single window. Now it does
- If the source window font or font size changed, and the window was later split, new text added to the bottom portion appeared with the old font and size. This bug was pointed out by J. F. Groote, and is fixed in version 3.96

TeXShop 3.95
- Change log not available for this version

TeXShop 3.94
- Change log not available for this version

TeXShop 3.92
- High Sierra has a bug which breaks updating the pageNumber field when scrolling in the Preview Window. TeXShop 3.91 has a workaround for this bug, but the workaround broke the ability to enter a new page number and go there. This is fixed. After going to a new page, click once in the pdf content region to activate page updates during scrolling
- TeXShop has two magic lines to activate tabs. The first, "useTabs", automatically adds "include" files as tabs, while the second, "useTabsWithFiles", gives the author much tighter control over which source files to use as tabs. Tommaso Pecorella wrote asking that the first command also automatically add "input" files as tabs. The reason I didn't do this at first is that the syntax for "input" allows situations that aren't really appropriate for tabs. For example, a source that is "input" can itself "input" other files. Some authors break the source into hundreds of pieces, inputting these pieces as necessary. So whether the request is appropriate or not depends on the writing style of the user. In TeXShop 3.92, the "useTabs" command will also create tabs for "input" files, but only if the user activates this feature with a hidden preference: defaults write TeXShop TabsAlsoForInputFiles YES

TeXShop 3.91
- Change log not available for this version

TeXShop 3.89
- Change log not available for this version

TeXShop 3.88
- In version 3.86, .bbl files were added to the list of files automatically removed by "Trash AUX Files". Two users complained, giving reasons. So these files are no longer automatically removed. Notice that there is a hidden preference to add file types to those removed, so users who want to remove.bbl files can still do so.
- The syntax parser had a bug which could crash TeXShop. This bug was discovered by Yusuke Terada, who provided a fix.
- Masson Thierry suggested three new features, and all are in version 3.88. He suggested adding frametitle to entries added automatically to the tags menu. This should be helpful when using the Beamer slides package.
- Masson suggested a new "magic line": % !TEX pdfSinglePage,When this line is added to the top of a source file, the resulting pdf preview will show single pages, even if the default is to show a single scrollable document. This feature is aimed at Beamer authors, who want slides to display one slide at a time, but other documents to scroll.
- Several years ago, Ramon Figueroa-Centeno provided beautiful macros to set the magic lines which determine the typesetting program, the encoding, and the program root. Immediately below these macros, the macro menu now has a menu listing all other possible magic lines as submenus. Selecting such a submenu adds the corresponding magic line at the current position of the cursor in the source editor. Thus users need no longer remember the syntax of these magic lines.

TeXShop 3.87
- The bug fix for Bibtex allowing citation keys with spaces turns out to be a bad idea. Bibtex documentation states that citation keys cannot have spaces, and the fix broke other user's Bibtex interaction. The fix has been removed. There are no other changes.

TeXShop 3.86
- The Chinese localization had overlapping text in Preferences; this is fixed
- Antti Knowles found two bugs and sent the code to fix them. When synctex is used to sync from the Preview window to the Source window, it colors the matching text yellow. After that in earlier versions of TeXShop, if a selection was made using only the keyboard, the selection would still be in yellow. The selection color would change to standard selection color only after a click of the mouse. This is fixed
- Knowles second fix concerns the autocomplete feature of BibTeX. If a latex label contains a space, the autocomplete feature would show the full label in the list, but selecting this label would only include the label up to the first space. The fix for this is a little iffy. If users of TeXShop and BibTeX run into problems, please write me immediately
- Tristan Hubsch pointed out that "hyperref tooltips" used with tables of contents and elsewhere could run off the page to the left or right. In that case, they were cut off. This annoying glitch is fixed (unless the page is so narrow that the tooltip could never fit on it)
- Added ".engine" and ".sh" (shell script) as file types that TeXShop can write
- At the request of Simon Robinson, addd ".bbl" and ".synctex(busy)" as file types which are automatically removed by the Remove AUX File commands
- The remaining items are all motivated by email sent by Bob Kerstetter. He reported that http://tidbits.com/article/17351 had an article about the language Markdown, listing editors used on the Macintosh to create these sources, and TeXShop was in that list. Markdown is a very simple markup language invented by John Gruber whose files can be easily converted to html, pdf, latex, and other languages. Many conversion programs are available free on the internet, including a program called "pandoc". In the ~/Library/TeXShop/Engines/Inactive program, there is a folder containing pandoc engines. But I discovered that the information about pandoc was out of date. The pandoc site now contains an open source install package for OS X, making it very easy to install pandoc. So I removed the existing engines, and placed a document called Pandoc.pdf in the pandoc folder, with links to the Gruber article and the pandoc site. Note that the pandoc site contains a large number of possible conversions, and details about how they work
- I also received email from Alan Munn, who tried to create stationery for Markdown files (.md files) and failed. This caused me to revise the Stationery feature of TeXShop slightly. Originally, users could create two kinds of files and place them in ~/Library/TeXShop/Stationery. First, they could create a piece of stationery, with extension ".tex". Then they could create a comment file with the same name and extension ".comment" describing the stationery. After that, the TeXShop Stationery menu showed available stationery, with descriptions of each possibility. It turns out that the extension assigned to stationery was irrelevant. So in TeXShop 3.86, stationery files can have any extension except ".comment", or no extension at all. The extension is actually never used. Stationery is treated just like blank windows in TeXShop, except that stationery pages are marked as "dirty." If you try to close one, or typeset one, or whatever, a dialog will appear asking you to name the file and save it to a location of your choosing. This dialog contains a pull-down menu of file types which TeXShop can write, and that menu is how users actually choose filetype. Markdown stationery can be saved with type ".md" in this way, and stationery for any other file type can be handled the same way
- The folder ~/Library/TeXShop/Engines/Inactive/pandoc contains two new engines. The first, Md2pdf.engine, converts a Markdown source file to a pdf file and opens the pdf file in TeXShop. The second, Md2HTML.engine, converts a Markdown source file to an HTML file and opens the HTML file in Safari. Users should note that many other conversion engines for Markdown are available on the internet, and in most cases it is very easy to write engine files which call these conversion engines
- A few people use TeXShop as a general editor. I'm one of them, but I sort of thought I was alone. If you use TeXShop to edit other things than .tex files, the syntax coloring feature of TeXShop can be annoying. TeXShop 3.86 has a new menu item which turns syntax coloring on or off. This applies to the source window at the top of the stack. Users can have several source windows, some using syntax coloring and some not. The old "Syntax Color" item in TeXShop Preferences is still there, but it now selects the default choice for syntax coloring when a new document is opened. Changing this Preference does not affect syntax coloring in documents already open. It would, of course, be wonderful if someone would write general syntax coloring code for TeXShop, so users could choose one scheme for Markdown, one for HTML, one for C code, etc. I don't intend to do that, but I'd gratefully accept the code from someone else

TeXShop 3.85
- TeXShop 3.82 introduced "useTabs", an easy way to add tabs to projects with a root file and chapter files. TeXShop 3.84 added "useTabsWithFiles", a second method of adding tabs requiring a little more work for a lot more flexibility. Unhappily, the code for this second method broke the first method
- TeXShop 3.85 again activates both methods
- In High Sierra, tabs can be given special short names in place of the names of the files they represent. As the number of tabs increases, this becomes more and more useful. The second method of adding tabs has always supported these shorter names. A similar technique is provided in TeXShop 3.85 for the first method
- The magic line containing "useTabs" can be followed by an optional list of short names as in this example: % !TEX useTabs (one, two, , short name, five)
- This additional parameter must be on the same line as "useTabs", but notice that single lines can wrap in the editor without adding a line feed. The short names are listed inside a pair of round brackets, and are separated by commas. White space at the beginning and end of a short name will be ignored, but a short name can contain more than one word, as in the above example. If the space between two commas is blank, the original name will be used for that file. If the list has fewer names than the number of tabs, original names will be used for the remaining tabs. If the list is longer than the number of tabs, names at the end will be ignored
- Version 3.85 runs on the original list of supported systems, including High Sierra. Tabs require Sierra and higher, and short names require High Sierra and higher. Short names can be input on Sierra, but they will be ignored on that system
- TeXShop 3.85 was compiled by XCode 8.3.3 running on Sierra. It runs fine on High Sierra, but the "short tab names" feature doesn't work there because XCode doesn't have API's for High Sierra. I tried compiling TeXShop on High Sierra using the beta copy of XCode provided for that system. The code worked fine in High Sierra and short tab names worked. But unfortunately, the resulting code had minor problems running on Sierra. The High Sierra version is available at the TeXShop web site at http://pages.uoregon.edu/koch/texshop/texshop.html
- The TeXShop 3.85 source code has one line commented out which must be activated to get short tab names on High Sierra. If you want to compile yourself on High Sierra, search the source file TSDocument.m for "High Sierra" and uncomment the following line of code: windowToTab.tab.title = self.includeFileShortNames[i]

TeXShop 3.84
- When version 3.82 of TeXShop was released, I said that it would be the final version of TeXShop until late fall. But bugs were discovered, so version 3.83 was released
- These versions of TeXShop created only half of the promised support for tabs, and I found that I couldn't stop in the middle. Version 3.84 completes tab support, and should finally be the last release until late fall. Note that tabs require Sierra or higher because Apple first added tab support in that version of macOS
- Tabs are not appropriate for all TeX projects. They work best on books and large articles with from five to fifteen chapters or divisions, each introduced with an include command. Some authors prefer to divide their project into many more pieces, perhaps one file per section, and then associating a tab with each file would product unmanageably many tabs
- TeXShop has two mechanisms to enhance Sierra tab support. The first is very simple. Within the top 20 lines of the root file, add the line % !TEX useTabs
- When this command is given, TeXShop itself searches for include files to associate with tabs; the mechanism should cover perhaps 70 percent of cases
- The second mechanism gives the user considerably more control over the tabs. Within the top 20 lines of the root file, add the line % !TEX useTabsWithFiles
- Below that, within the top 50 lines of the root file, add a line for each tab % !TEX tabbedFile{chapter1/Introduction.tex} (One)
- In this command, a path to the file shown in the tab is given in curly brackets. In the example, the path starts from the folder containing the project root file, but see more details below. Notice that the file extension must be included. That is because the second mechanism allows pdf, tiff, jpg, log, aux, and other files as tabs. Authors sometimes give source files long descriptive names, which makes the tab titles very long. The final piece of the above line in round brackets is optional, and gives a shorter tab name
- The optional short name will only be recognized in High Sierra, because it requires additional Apple API first made available there. Feel free to use the term in Sierra; it will cause no harm there, but will be ignored
- Finally, we list some technical details. The first mechanism searches for include lines after begin{document} in the body of the root file. It is common to list files without extensions, and in that case TeXShop adds the extension ".tex" when creating the tab. In the second mechanism, however, TeXShop will not change the extension given by the user, or add a missing extension, because tab files can have unusual types so the extensions provide crucial information. Both methods create at most 20 tabs and ignore lines which might create more of them. The "useTabs" mechanism only works if the root file has at most 20,000 characters, to avoid very long searches for include lines in gigantic root files
- If a window with tabs is left open when TeXShop is closed, then the next time TeXShop is opened, macOS opens the window and recreates the tabs. The new tab mechanism recognizes this behavior and lets macOS do the job without itself creating tabs. However, macOS does not understand tabs made from pdf files, graphic files, and a few others, so some of the tabs may be missing. It is easy to get these tabs back. Close the document and then reopen it. This forces TeXShop to recreate the tabs, and then all tabs come back. Or open the missing files yourself and drag their windows to missing tabs. (This macOS behavior is not a bug; other features of TeXShop depend on it. We cannot have everything)
- Finally, a word about the path information between the curly brackets in the "tabbedFile" magic lines. Three types of path strings are recognized. The first are strings that start in the location of the root file. Examples include {chapter1.tex} and {Chapter1/Introduction.tex}. Longer strings of directories are allowed. When it sees this sort of string, TeXShop prepends the full path to the folder containing the root file
- Another possibility is a path starting at your home directory, like {~/Galois/Equations.tex}. Here ~ denotes the home directory, so this file is probably not in the project directory
- Finally, TeXShop recognizes full paths like {/Users/koch/Galois/Equations.tex}
- If you use still more Unix conventions, they may or may not work. No guarantees. Tests suggest that spaces are allowed in both directory names and file names, but I'm loathe to recommend them
- There are a few tricky points. The Finder often lists TeX source files without the ".tex" extension, but this extension is just hidden, not absent. It must be written as part of the tab file path. (During testing, I was confused by this point several times)
- When TeXShop is asked to create a tab, it opens the file exactly as if a user had dragged the file icon to TeXShop and dropped it there. Then the window described in the tab is "tabbed." This creates a few surprising cases that look like bugs but aren't. For example, then TeXShop opens a dvi file, it actually converts the file to pdf using dvips and Ghostscript, and then opens the pdf file. So tabbing a dvi file will give a pdf file as a tab
- Here is another surprising case. Suppose that you are working on a project named "Galois.tex" and you earlier created a project named "Abel.tex". When you open Galois.tex, you want Abel.tex as a tab so you can refer to that source file as you write Galois. But if you drop the icon for Galois.tex on TeXShop, both Galois.tex and Galois.pdf will open in separate windows. Similarly dropping the icon for Abel.tex on TeXShop will open Abel.tex and Abel.pdf. After tabbing occurs, you'll have a tabbed window containing Galois.tex and Abel.tex, and you'll have Galois.pdf in a separate window. But you'll also have Abel.pdf in another window. The existence of this extra pdf file looks like a bug, but isn't
- This release of TeXShop was compiled by XCode 8.3.3 running on Sierra. It runs fine on High Sierra, but the "short tab names" feature doesn't work there because XCode doesn't have API's for High Sierra. I tried compiling TeXShop on High Sierra using the beta copy of XCode provided for that system. The code worked fine in High Sierra and short tab names worked. But unfortunately, the resulting code had minor problems running on Sierra. No doubt these will be fixed before the release of High Sierra
- Consequently, if you are beta testing High Sierra and want to use short tab names, you'll need to search the source file TSDocument.m for "High Sierra" and uncomment the following line of code windowToTab.tab.title = self.includeFileShortNames[i]
- Then compile on High Sierra

TeXShop 3.83
- Murray Eisenberg discovered problems with the new "useTabs" feature and sent me his full source code to debug. This proved extremely useful! The problems I foresaw with this feature have not materialized, but Eisenberg's source revealed more elementary and embarrassing bugs, now fixed
- The only files which receive tabs are those loaded by include{myfile} statements after begin{document} in the root file. Here "myfile" can be a file name, partial path, or full path. Murray's document loaded chapters in a more complicated way, but was easily modified to meet this condition. It would be easy to extend TeXShop so an alternate method could also be used, in which th
