schhist - Graphical revision history of schematics
|
|
==================================================
|
|
|
|
The schhist system walks the git revision history of a KiCad project
|
|
and produces Web-browseable graphical differences of the schematics.
|
|
|
|
It does so by checking out each revision from git, sanitizing the
|
|
project to prevent problems what would cause eeschema to stop and
|
|
display an error dialog, using eeschema to "plot" the project to
|
|
Postscript, making some small adjustments (position, line width) to
|
|
the Postscript, converting it to PPM with Ghostscript, making a
|
|
pixel-wise comparison of revisions, and arranging the resulting
|
|
images in an HTML page. Further more, sub-pages with magnifications
|
|
and PDF files are generated.

gitwhoareyounow
|
|
---------------
|
|
|
|
gitwhoareyounow is used to find a single identity for files that have been
|
|
renamed in the history of a project.
|
|
|
|
E.g., if a file foo.c is created in revision 1 (assuming successive revisions
|
|
numbered 1, 2, etc.) and renamed to bar.c in revision 2, gitwhoareyounow
|
|
would then return the name bar.c for this file in any revision we consider.
|
|
|
|
gitwhoareyounow has to be given a repository in which the historical commit
|
|
has been checked out, and the name the file had in that commit.
|
|
|
|
Example:
|
|
|
|
$ git init
|
|
$ date >foo.c
|
|
# git add foo.c
|
|
# git commit -m "foo.c, rev 1"
|
|
$ git mv foo.c bar.c
|
|
$ git commit -m "foo.c renamed to bar.c, rev 2"
|
|
$ git checkout HEAD~1
|
|
$ ls
|
|
foo.c
|
|
$ gitwhoareyounow . foo.c
|
|
bar.c
|
|
|
|
|
|
Multiple files may use the same identity
|
|
- - - - - - - - - - - - - - - - - - - -
|
|
|
|
E.g., if a file foo.c is created in revision 1, deleted in revision 3, and
|
|
then a new file named foo.c is created in revision 4, gitwhoareyounow would
|
|
call both of them foo.c
|
|
|
|
|
|
Multiple files sharing the same identity can conflict
|
|
- - - - - - - - - - - - - - - - - - - - - - - - - - -
|
|
|
|
E.g., taking the first example with foo.c renamed to bar.c in revision 3, if
|
|
a file bar.c existed in revision 1 but was deleted in revision 2,
|
|
gitwhoareyounow running on revision 1 would identify both the foo.c and the
|
|
bar.c as bar.c
|
|
|
|
gitwhoareyounow does not try to resolve such conflicts. This is already
|
|
complex enough as it is :-)
