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

19 | The file you are reading contains more informations about the SyncTeX parser history. |
---|
20 | |
---|
21 | In order to support SyncTeX in a viewer, it is sufficient to include |
---|
22 | in the source the files synctex_parser.h and synctex_parser.c. |
---|
23 | The synctex parser usage is described in synctex_parser.h header file. |
---|
24 | |
---|
25 | The other files are used by tex engines or by the synctex command line utility: |

59 | Version: |
---|
60 | -------- |
---|
61 | This is version 1, which refers to the synctex output file format. |
---|
62 | The files are identified by a build number. |
---|
63 | In order to help developers to automatically manage the version and build numbers |
---|
64 | and download the parser only when necessary, the synctex_parser.version |
---|
65 | is an ASCII text file just containing the current version and build numbers. |
---|
66 | |
---|
67 | History: |
---|
68 | -------- |
---|
69 | 1.1: Thu Jul 17 09:28:13 UTC 2008 |
---|
70 | - First official version available in TeXLive 2008 DVD. |
---|
71 | Unfortunately, the backwards synchronization is not working properly mainly for ConTeXt users, see below. |
---|
72 | 1.2: Tue Sep 2 10:28:32 UTC 2008 |
---|
73 | - Correction for ConTeXt support in the edit query. |
---|
74 | The previous method was assuming that TeX boxes do not overlap, |
---|
75 | which is reasonable for LaTeX but not for ConTeXt. |
---|
76 | This assumption is no longer considered. |
---|
77 | 1.3: Fri Sep 5 09:39:57 UTC 2008 |
---|
78 | - Local variable "read" renamed to "already_read" to avoid conflicts. |
---|
79 | - "inline" compiler directive renamed to "SYNCTEX_INLINE" for code support and maintenance |
---|
80 | - _synctex_error cannot be inlined due to variable arguments (thanks Christiaan Hofman) |
---|
81 | - Correction in the display query, extra boundary nodes are used for a more precise forwards synchronization |
---|
82 | 1.4: Fri Sep 12 08:12:34 UTC 2008 |
---|
83 | - For an unknown reason, the previous version was not the real 1.3 (as used in iTeXMac2 build 747). |
---|
84 | As a consequence, a crash was observed. |
---|
85 | - Some typos are fixed. |
---|
86 | 1.6: Mon Nov 3 20:20:02 UTC 2008 |
---|
87 | - The bug that prevented synchronization with compressed files on windows has been fixed. |
---|
88 | - New interface to allow system specific customization. |
---|
89 | - Note that some APIs have changed. |
---|
90 | 1.8: Mer 8 jul 2009 11:32:38 UTC |
---|
91 | Note that version 1.7 was delivered privately. |
---|
92 | - bug fix: synctex was causing a memory leak in pdftex and xetex, thus some processing speed degradation |
---|
93 | - bug fix: the synctex command line tool was broken when updating a .synctex file |
---|
94 | - enhancement: better accuracy of the synchronization process |
---|
95 | - enhancement: the pdf output file and the associated .synctex file no longer need to live in the same directory. |
---|
96 | The new -d option of the synctex command line tool manages this situation. |
---|
97 | This is handy when using something like tex -output-directory=DIR ... |
---|
98 | 1.9: Wed Nov 4 11:52:35 UTC 2009 |
---|
99 | - Various typo fixed |
---|
100 | - OutputDebugString replaced by OutputDebugStringA to deliberately disable unicode preprocessing |
---|
101 | - New conditional created because OutputDebugStringA is only available since Windows 2K professional |
---|
102 | 1.10: Sun Jan 10 10:12:32 UTC 2010 |
---|
103 | - Bug fix in synctex_parser.c to solve a synchronization problem with amsmath's gather environment. |
---|
104 | Concerns the synctex tool. |
---|
105 | 1.11: Sun Jan 17 09:12:31 UTC 2010 |
---|
106 | - Bug fix in synctex_parser.c, function synctex_node_box_visible_v: 'x' replaced by 'y'. |
---|
107 | Only 3rd party tools are concerned. |
---|
108 | 1.12: Mon Jul 19 21:52:10 UTC 2010 |
---|
109 | - Bug fix in synctex_parser.c, function __synctex_open: the io_mode was modified even in case of a non zero return, |
---|
110 | causing a void .synctex.gz file to be created even if it was not expected. Reported by Marek Kasik concerning a bug on evince. |
---|
111 | 1.13: Fri Mar 11 07:39:12 UTC 2011 |
---|
112 | - Bug fix in synctex_parser.c, better synchronization as suggested by Jan Sundermeyer (near line 3388). |
---|
113 | - Stronger code design in synctex_parser_utils.c, function _synctex_get_name (really neutral behavior). |
---|
114 | Only 3rd party tools are concerned. |
---|
115 | 1.14: Fri Apr 15 19:10:57 UTC 2011 |
---|
116 | - taking output_directory into account |
---|
117 | - Replaced FOPEN_WBIN_MODE by FOPEN_W_MODE when opening the text version of the .synctex file. |
---|
118 | - Merging with LuaTeX's version of synctex.c |
---|
119 | 1.15: Fri Jun 10 14:10:17 UTC 2011 |
---|
120 | This concerns the synctex command line tool and 3rd party developers. |
---|
121 | TeX and friends are not concerned by these changes. |
---|
122 | - Bug fixed in _synctex_get_io_mode_name, sometimes the wrong mode was returned |
---|
123 | - Support for LuaTeX convention of './' file prefixing |
---|
124 | 1.16: Tue Jun 14 08:23:30 UTC 2011 |
---|
125 | This concerns the synctex command line tool and 3rd party developers. |
---|
126 | TeX and friends are not concerned by these changes. |
---|
127 | - Better forward search (thanks Jose Alliste) |
---|
128 | - Support for LuaTeX convention of './' file prefixing now for everyone, not only for Windows |
---|
129 | 1.17: Fri Oct 14 08:15:16 UTC 2011 |
---|
130 | This concerns the synctex command line tool and 3rd party developers. |
---|
131 | TeX and friends are not concerned by these changes. |
---|
132 | - synctex_parser.c: cosmetic changes to enhance code readability |
---|
133 | - Better forward synchronization. |
---|
134 | The problem occurs for example with LaTeX \item command. |
---|
135 | The fact is that this command creates nodes at parse time but these nodes are used only |
---|
136 | after the text material of the \item is displayed on the page. The consequence is that sometimes, |
---|
137 | forward synchronization spots an irrelevant point from the point of view of the editing process. |
---|
138 | This was due to some very basic filtering policy, where a somehow arbitrary choice was made when |
---|
139 | many different possibilities where offered for synchronisation. |
---|
140 | Now, forward synchronization prefers nodes inside an hbox with as many acceptable spots as possible. |
---|
141 | This is achieved with the notion of mean line and node weight. |
---|
142 | - Adding support for the new file naming convention with './' |
---|
143 | + function synctex_ignore_leading_dot_slash_in_path replaces synctex_ignore_leading_dot_slash |
---|
144 | + function _synctex_is_equivalent_file_name is more permissive |
---|
145 | Previously, the function synctex_scanner_get_tag would give an answer only when |
---|
146 | the given file name was EXACTLY one of the file names listed in the synctex file. |
---|
147 | The we added some changes accepting for example 'foo.tex' instead of './foo.tex'. |
---|
148 | Now we have an even looser policy for dealing with file names. |
---|
149 | If the given file name does not match exactly one the file names of the synctex file, |
---|
150 | then we try to match the base names. If there is only one match of the base names, |
---|
151 | then it is taken as a match for the whole names. |
---|
152 | The base name is defined as following: |
---|
153 | ./foo => foo |
---|
154 | /my///.////foo => foo |
---|
155 | /foo => /foo |
---|
156 | /my//.foo => /my//.foo |
---|
157 | 1.17: Tue Mar 13 10:10:03 UTC 2012 |
---|
158 | - minor changes, no version changes |
---|
159 | - syntax man pages are fixed as suggested by M. Shimata |
---|
160 | see mail to tex-live@tug.org titled "syntax.5 has many warnings from groff" and "syntax.1 use invalid macro for mdoc" |
---|
161 | 1.17: Tue Jan 14 09:55:00 UTC 2014 |
---|
162 | - fixed a segfault, from Sebastian Ramacher |
---|
163 | 1.17: Mon Aug 04 |
---|
164 | - fixed a memory leak |
---|
165 | 1.18: Thu Jun 25 11:36:05 UTC 2015 |
---|
166 | - nested sheets now fully supported (does it make sense in TeX) |
---|
167 | - cosmetic changes: uniform indentation |
---|
168 | - suppression of warnings, mainly long/int ones. In short, zlib likes ints when size_t likes longs. |
---|
169 | - CLI synctex tool can build out of TeXLive (modulo appropriate options passed to the compiler) |
---|
