Change tracking for LyX 1.3
John Levon, Johnathan Burchill, Jane McKean
Change tracking is not yet included in any official version of LyX. However, John Levon's original patch has been adapted to subsequent LyX releases by Johnathan Burchill and by Jane McKean's team of engineers at PathScale, Inc. If you decide to use this patch then you can be assured that your LyX files will be understood by future versions of LyX (notably version 1.4.0) which will support change tracking "out of the box".
This feature, similar to that found in Microsoft Word and others, makes collaboration on a document a cinch. It provides a way to track changes made to a document, and later approve, reject, or modify such changes. To freeze a document for change tracking, use the Edit→Change Tracking menu:
When enabled, any edits made to a document are tracked. Deleted text is marked in red and struck through, whilst added text is marked in blue; in addition a changebar is added to the margin. With the dvipost software installed, such marks can even be exported to PostScript and PDF (the latter, however, only with ps2pdf and dvipdfm; pdflatex does not work).
Send a change-tracked document off for review to a colleague, and let them make changes - when you receive it back, you can use the Merge Changes dialog to review his changes.
Once all marked changes have been processed, change tracking can be disabled again to allow normal editing.
Some more screenshots
Note: This patch may make your LyX unusable. In particular, I have managed to make LyX crash at will by cut-and-pasting "changed text" that contains an inset. Solution? Don't cut-and-paste "changed text" that contains an inset. I don't care to spend the time right now to track down the problem. At any rate, no data was lost. This patch comes with absolutely no warranty. Use it at your own risk!.
Change bars with LyX 1.3.6
With the help of engineering here at PathScale, Jane McKean has put together a patch for using change bars with 1.3.6. Here's a description of the patch:
This is an updated version of John Levon's change tracking patch, supporting LyX 1.3.6. Changes from the previous version include removal of
The most important fix is to the author name and email entries. Previously, LyX would use the GECOS information without modification, which causes a problem in many environments in which values like the user's phone number and office number were included as a comma-separated list. Now we only use the text leading up to the first comma. Furthermore, the previous version would attempt to write a
This change is important because it may change a user's author information. This could result in an additional author entry being created, which could cause confusion. To fix this, change the "\author" entry in
John Levon's page on his change tracking patch can be found here: http://www.lyx.org/devel/changetracking.php
It requires Erich Früstück's "dvipost" package, which can be found here: http://freshmeat.net/projects/dvipost/

Applying the patch
To apply the patch, cd to the LyX source directory and
$ bzip2 -d lyx-1.3.6-changebars.diff.bz2 $ patch -p1 < lyx-1.3.6-change_tracking.diff
Then go ahead with the regular build procedure:
$ configure -with-frontend=qt $ make
If your document uses the
If you don't see your changes in the pdf-output file when you use RevTeX 4, try using the preprint option or a single column layout. /Kurt P

Merging back into the LyX 1.3.x tree?
Would anybody care to merge this patch (when it supposedly supports both Qt and xforms) to the trunk? /Matěj Cepl
That will presumably not happen. The 1.3.x series will only get bug fixes, no new features (and certainly no file format change, which is necessary for change tracking). However, 1.4 will ship with change tracking /Jürgen Spitzmüller.
Marking floats as deleted/inserted
Based on the suggestion in bug 1756, here is an example of how floats could be marked deleted or inserted using change tracking. This example was created by adding two new float styles to the float package. Any suggestions? /JKBurchill 20050301
Downgrading 1.4 files to 1.3 files with change tracking enabled
Starting from release 1.3.6, LyX is able to read an edit files generated with LyX 1.4. The conversion process implies that some of those 1.4 features not available in 1.3 will either be removed or reproduced with the help of LaTeX (ERT).
Since change tracking is not officially supported in LyX 1.3 it is, by default, removed when downgrading a file created with LyX 1.4. If you want to retain the change tracking, you should remove these calls from the bottom of
Upgrading from 1.3 to 1.4 will work out of the box. /JAMatos 20050715
