[GSoC] Scripts to be conversted into builtins

[GSoC] Scripts to be conversted into builtins

[Yash Yadav]

Hello,

I am a student going through the GSoC process.

In the project ideas listed there is one idea talking of conversion of 
scripts to builtins. This interests me but no pointer forward is given 
and I'd like to dive more into that idea and go through the script(s).

So, where should I look further from here?


Thanks,

Yash Yadav

One good place to start is to start reading at:

    git log -p --stat --full-diff --reverse 74703a1e4d.. -- 'builtin/*--helper.c'

And then search for git-.*\.sh in your pager. These are a bunch of
commits where the bisect, rebase and submodule helpers have had their
shellscript code incrementally replaced by C.

Yeah, and we have been proposing this kind of GSoC projects for a
number of years now, so we have had a number of GSoC students doing
this kind of projects, and therefore a lot of information about their
projects is available in the mailing list archive.

One concrete example how a script was converted can be seen here:

https://github.com/git/git/compare/b7786bb4b09%5E...b7786bb4b09%5E2

(This is the patch series that replaced the scripted version of the
`difftool` by the one written in portable C.)

But maybe you want to look at the micro-projects first, to see how you
like to work on Git's source code, and with the Git mailing list?
