This file is part of the SyncTeX package.

|
||
|
|
The Synchronization TeXnology named SyncTeX is a new feature
|
||
|
|
of recent TeX engines designed by Jerome Laurens.
|
||
|
|
It allows to synchronize between input and output, which means to
|
||
|
|
navigate from the source document to the typeset material and vice versa.

||

This package is mainly for developers, it mainly contains the following files:
|
||
|
|
|
||
|
|
synctex_parser_readme.txt
|
||
|
|
synctex_parser_version.txt
|

|
||
|
|
synctex_parser.h
|
||
|
|
synctex_parser.c
|
||
|
|
|
||
|
|
The file you are reading contains more informations about the SyncTeX parser history.
|
||
|
|
|
||
|
|
In order to support SyncTeX in a viewer, it is sufficient to include
|
||
|
|
in the source the files synctex_parser.h and synctex_parser.c.
|
||
|
|
The synctex parser usage is described in synctex_parser.h header file.
|
||
|
|
|
||
|
|
The other files are used by tex engines or by the synctex command line utility:

Version:
|
||
|
|
--------
|
||
|
|
This is version 1, which refers to the synctex output file format.
|
||
|
|
The files are identified by a build number.
|
||
|
|
In order to help developers to automatically manage the version and build numbers
|
||
|
|
and download the parser only when necessary, the synctex_parser.version
|
||
|
|
is an ASCII text file just containing the current version and build numbers.
|
||
|
|
|
||
|
|
History:
|
||
|
|
--------
|
||
|
|
1.1: Thu Jul 17 09:28:13 UTC 2008
|
||
|
|
- First official version available in TeXLive 2008 DVD.
|
||
|
|
Unfortunately, the backwards synchronization is not working properly mainly for ConTeXt users, see below.
|
||
|
|
1.2: Tue Sep 2 10:28:32 UTC 2008
|
||
|
|
- Correction for ConTeXt support in the edit query.
|
||
|
|
The previous method was assuming that TeX boxes do not overlap,
|
||
|
|
which is reasonable for LaTeX but not for ConTeXt.
|
||
|
|
This assumption is no longer considered.
|
||
|
|
1.3: Fri Sep 5 09:39:57 UTC 2008
|
||
|
|
- Local variable "read" renamed to "already_read" to avoid conflicts.
|
||
|
|
- "inline" compiler directive renamed to "SYNCTEX_INLINE" for code support and maintenance
|
||
|
|
- _synctex_error cannot be inlined due to variable arguments (thanks Christiaan Hofman)
|
||
|
|
- Correction in the display query, extra boundary nodes are used for a more precise forwards synchronization
|
||
|
|
1.4: Fri Sep 12 08:12:34 UTC 2008
|
||
|
|
- For an unknown reason, the previous version was not the real 1.3 (as used in iTeXMac2 build 747).
|
||
|
|
As a consequence, a crash was observed.
|
||
|
|
- Some typos are fixed.
|
||
|
|
1.6: Mon Nov 3 20:20:02 UTC 2008
|
||
|
|
- The bug that prevented synchronization with compressed files on windows has been fixed.
|
||
|
|
- New interface to allow system specific customization.
|
||
|
|
- Note that some APIs have changed.
|
||
|
|
1.8: Mer 8 jul 2009 11:32:38 UTC
|
||
|
|
Note that version 1.7 was delivered privately.
|
||
|
|
- bug fix: synctex was causing a memory leak in pdftex and xetex, thus some processing speed degradation
|
||
|
|
- bug fix: the synctex command line tool was broken when updating a .synctex file
|
||
|
|
- enhancement: better accuracy of the synchronization process
|
||
|
|
- enhancement: the pdf output file and the associated .synctex file no longer need to live in the same directory.
|
||
|
|
The new -d option of the synctex command line tool manages this situation.
|
||
|
|
This is handy when using something like tex -output-directory=DIR ...
|
||
|
|
1.9: Wed Nov 4 11:52:35 UTC 2009
|
||
|
|
- Various typo fixed
|
||
|
|
- OutputDebugString replaced by OutputDebugStringA to deliberately disable unicode preprocessing
|
||
|
|
- New conditional created because OutputDebugStringA is only available since Windows 2K professional
|
||
|
|
1.10: Sun Jan 10 10:12:32 UTC 2010
|
||
|
|
- Bug fix in synctex_parser.c to solve a synchronization problem with amsmath's gather environment.
|
||
|
|
Concerns the synctex tool.
|
||
|
|
1.11: Sun Jan 17 09:12:31 UTC 2010
|
||
|
|
- Bug fix in synctex_parser.c, function synctex_node_box_visible_v: 'x' replaced by 'y'.
|
||
|
|
Only 3rd party tools are concerned.
|
||
|
|
1.12: Mon Jul 19 21:52:10 UTC 2010
|
||
|
|
- Bug fix in synctex_parser.c, function __synctex_open: the io_mode was modified even in case of a non zero return,
|
||
|
|
causing a void .synctex.gz file to be created even if it was not expected. Reported by Marek Kasik concerning a bug on evince.
|
||
|
|
1.13: Fri Mar 11 07:39:12 UTC 2011
|
||
|
|
- Bug fix in synctex_parser.c, better synchronization as suggested by Jan Sundermeyer (near line 3388).
|
||
|
|
- Stronger code design in synctex_parser_utils.c, function _synctex_get_name (really neutral behavior).
|
||
|
|
Only 3rd party tools are concerned.
|
||
|
|
1.14: Fri Apr 15 19:10:57 UTC 2011
|
||
|
|
- taking output_directory into account
|
||
|
|
- Replaced FOPEN_WBIN_MODE by FOPEN_W_MODE when opening the text version of the .synctex file.
|
||
|
|
- Merging with LuaTeX's version of synctex.c
|
||
|
|
1.15: Fri Jun 10 14:10:17 UTC 2011
|
||
|
|
This concerns the synctex command line tool and 3rd party developers.
|
||
|
|
TeX and friends are not concerned by these changes.
|
||
|
|
- Bug fixed in _synctex_get_io_mode_name, sometimes the wrong mode was returned
|
||
|
|
- Support for LuaTeX convention of './' file prefixing
|
||
|
|
1.16: Tue Jun 14 08:23:30 UTC 2011
|
||
|
|
This concerns the synctex command line tool and 3rd party developers.
|
||
|
|
TeX and friends are not concerned by these changes.
|
||
|
|
- Better forward search (thanks Jose Alliste)
|
||
|
|
- Support for LuaTeX convention of './' file prefixing now for everyone, not only for Windows
|
||
|
|
1.17: Fri Oct 14 08:15:16 UTC 2011
|
||
|
|
This concerns the synctex command line tool and 3rd party developers.
|
||
|
|
TeX and friends are not concerned by these changes.
|
||
|
|
- synctex_parser.c: cosmetic changes to enhance code readability
|
||
|
|
- Better forward synchronization.
|
||
|
|
The problem occurs for example with LaTeX \item command.
|
||
|
|
The fact is that this command creates nodes at parse time but these nodes are used only
|
||
|
|
after the text material of the \item is displayed on the page. The consequence is that sometimes,
|
||
|
|
forward synchronization spots an irrelevant point from the point of view of the editing process.
|
||
|
|
This was due to some very basic filtering policy, where a somehow arbitrary choice was made when
|
||
|
|
many different possibilities where offered for synchronisation.
|
||
|
|
Now, forward synchronization prefers nodes inside an hbox with as many acceptable spots as possible.
|
||
|
|
This is achieved with the notion of mean line and node weight.
|
||
|
|
- Adding support for the new file naming convention with './'
|
||
|
|
+ function synctex_ignore_leading_dot_slash_in_path replaces synctex_ignore_leading_dot_slash
|
||
|
|
+ function _synctex_is_equivalent_file_name is more permissive
|
||
|
|
Previously, the function synctex_scanner_get_tag would give an answer only when
|
||
|
|
the given file name was EXACTLY one of the file names listed in the synctex file.
|
||
|
|
The we added some changes accepting for example 'foo.tex' instead of './foo.tex'.
|
||
|
|
Now we have an even looser policy for dealing with file names.
|
||
|
|
If the given file name does not match exactly one the file names of the synctex file,
|
||
|
|
then we try to match the base names. If there is only one match of the base names,
|
||
|
|
then it is taken as a match for the whole names.
|
||
|
|
The base name is defined as following:
|
||
|
|
./foo => foo
|
||
|
|
/my///.////foo => foo
|
||
|
|
/foo => /foo
|
||
|
|
/my//.foo => /my//.foo
|
||

|
1.17: Tue Mar 13 10:10:03 UTC 2012
|
||
|
|
- minor changes, no version changes
|
||
|
|
- syntax man pages are fixed as suggested by M. Shimata
|
||
|
|
see mail to tex-live@tug.org titled "syntax.5 has many warnings from groff" and "syntax.1 use invalid macro for mdoc"
|
||
|
|
1.17: Tue Jan 14 09:55:00 UTC 2014
|
||
|
|
- fixed a segfault, from Sebastian Ramacher
|
||
|
|
1.17: Mon Aug 04
|
||
|
|
- fixed a memory leak
|
||
|
|
1.18: Thu Jun 25 11:36:05 UTC 2015
|
||
|
|
- nested sheets now fully supported (does it make sense in TeX)
|
||
|
|
- cosmetic changes: uniform indentation
|
||
|
|
- suppression of warnings, mainly long/int ones. In short, zlib likes ints when size_t likes longs.
|
||
|
|
- CLI synctex tool can build out of TeXLive (modulo appropriate options passed to the compiler)
|
