This directory used to contain scripted implementations of builtins
|
|
|
|
|
that have since been rewritten in C.
|
|
|
|
|
|
|
|
|
|
They have now been removed, but can be retrieved from an older commit
|
|
|
|
|
that removed them from this directory.

|
They're interesting for their reference value to any aspiring plumbing
|
|
|
|
|
users who want to learn how pieces can be fit together, but in many
|
|
|
|
|
cases have drifted enough from the actual implementations Git uses to
|
|
|
|
|
be instructive.

Other things that can be useful:
|
|
|
|
|
|
|
|
|
|
* Some commands such as git-gc wrap other commands, and what they're
|
|
|
|
|
doing behind the scenes can be seen by running them under
|
|
|
|
|
GIT_TRACE=1
|
|
|
|
|
|
|
|
|
|
* Doing `git log` on paths matching '*--helper.c' will show
|
|
|
|
|
incremental effort in the direction of moving existing shell
|
|
|
|
|
scripts to C.
