Design

I want single file\dir revisions to display in a gui windows

• I do not want re-implemenet much of gitk or gui-gui
• I just want to have my own function
  • I want single file versions just a click away.
  • if possible I also want a deleted file list with all the old versions for each file
  • all complement for my muse-git doc system

related projects

search git in SF, then I got:

• QGit viewer
• http://viewgit.sourceforge.net/requirements
• gitview —gtk based
• ugit —in python

implementation

• a engine in C, try to use git-core api, but can start with gitk commands
• a GUI in Qt
• write glue in Python
• write web interface in the future [The Art of Unix Programming]
• have config file
• transfer data between files with tmp file, or dbus?

Phylosophy

• Software Is a Many-Layered Thing
• the smaller, the better
• simpleness wins at last

Tips

Download the git offical tar ball, then have a look at git.c to know how to implement the engine.

git log —follow auth_for_yum/

the gitk source file is more than 10.000 long, in a single file. Tcl is esay, but I hate a file so big.

luckly I mainly care about the sys command after exec, so I just need to search exec

one file diff

actually what I want to know is how to get the diff files

external_diff_get_one_file

get diff

Now I want to have the pactches for out Then I only need git log --follow out Do:

peter@cow:~/test-repo$ git diff ff39ed298a367cf971fc647beea6a6d4d8451ba3  2a165290ca21bf75c54c7558ddc51a478d9887b7 >out-1.patch
peter@cow:~/test-repo$ git diff 2a165290ca21bf75c54c7558ddc51a478d9887b7 bdaf3c85b000ee721f3f10022bd7af6c9105bde9>out-2.patch
peter@cow:~/test-repo$ ls
ff  out  out-1.patch  out-2.patch
peter@cow:~/test-repo$ vim out-1.patch
peter@cow:~/test-repo$ vim out-2.patch
peter@cow:~/test-repo$ ls
ff  out  out-1.patch  out-2.patch
peter@cow:~/test-repo$

Then I get all the patches for the file named out, that means I have all the revisions as well. Note: we can use diff -u above to get a universaul diff

then same can be done to get the history of ff/

I want this because I may some times, get a small project(a subdir, github:python/web/), out of a big one(like my github:python/)

gitbro-egg

I suddenly want this

$cd edocs/
$gitbro-egg yum.muse
$cd ..
$cd yum.repo #now we get a small repo for the file yum.muse only
$gitk

I also want this for dirs, then I can clear see the changes I made to a single file or a dir. I do not need to have my own gui tool

• it will be a gitbro front-end
• it just read and process output-gitbro/

if I can use this, then I can have a very perfect egg gitrepo

git-commit(1)
--reuse-message=<commit>
Take an existing commit object, and reuse the log message and the authorship information (including the timestamp) when creating the commit.

if a perfect one is difficult, then I just let the Author and Date be, I just commit with the original message that is enough to fully understand the code.
