DESCRIPTION

15       The schdiff program will use ImageMagick(1) to display a graphical diff
16       of two gschem schematic files.  It's most useful when combined  with  a
17       revision  control  system  so  it can compare two revisions of the same
18       file, review changes, etc.  However, it is limited in that it can  only
19       compare  two files at a time; it cannot diff entire directories nor can
20       it diff an entire revision (unless  that  revision  affected  only  one
21       file).   It can easily be configured to work with most revision control
22       systems.  Here are instructions for three:
23
24       git: Use the difftool command exactly as you would use diff , but  sup‐
25       ply the -x schdiff option.
26
27       mercurial:  Use the schdiff command exactly as you would use diff , but
28       add the following lines to your .hgrc:
29
30                [extensions]
31                hgext.extdiff =
32                [extdiff]
33                cmd.schdiff = schdiff
34
35       subversion: Use the diff command like normal, but supply the --diff-cmd
36       schdiff option.

EXAMPLES

40       Use git to view the changes to a file between two revisions
41              git difftool -x schdiff 182110f690c51eb53ea1799fd022e87322d742e3
42              039e012397f2638d1577dd7c80fb862a5503dbfd cpu.sch
43
44
45       Use mercurial to see all the changes since a specific revision
46              hg schdiff -r 8442880f9835 cpld.sch
47
48
49       Use subversion to review a specific revision
50              svn diff --diff-cmd schdiff -c 49 power.sch
