Changes In Branch diffBinExternal Excluding Merge-Ins
This is equivalent to a diff from 97f68e61da to 064afb225a
2012-10-02
| ||
22:59 | Merge the enhancements that adds the "diff-binary" setting for passing binary files to the external diff program. check-in: f8339c2743 user: drh tags: trunk | |
2012-09-30
| ||
09:29 | The 'binary-glob' setting is a versionable project setting and should be listed with the others. check-in: 6ef41eeffe user: mistachkin tags: trunk | |
07:39 | Make sure the new command line options are always processed; however, wait until after the settings are available. Closed-Leaf check-in: 064afb225a user: mistachkin tags: diffBinExternal | |
06:25 | Add support for skipping binary files when using an external diff program. The existing 'binary-glob' setting and new 'diff-binary' boolean setting control this feature. check-in: c50eb50718 user: mistachkin tags: diffBinExternal | |
01:43 | Fix typo in comment. check-in: 97f68e61da user: mistachkin tags: trunk | |
2012-09-29
| ||
14:08 | Make the "--tk" option to the "diff" command also imply the "-i" option to force the use of the internal diff engine. check-in: 5a4fbb0a28 user: drh tags: trunk | |
