From 74703a1e4dfc5affcb8944e78b53f0817b492246 Mon Sep 17 00:00:00 2001 From: Stefan Beller Date: Wed, 2 Sep 2015 14:42:24 -0700 Subject: submodule: rewrite `module_list` shell function in C Most of the submodule operations work on a set of submodules. Calculating and using this set is usually done via: module_list "$@" | { while read mode sha1 stage sm_path do # the actual operation done } Currently the function `module_list` is implemented in the git-submodule.sh as a shell script wrapping a perl script. The rewrite is in C, such that it is faster and can later be easily adapted when other functions are rewritten in C. git-submodule.sh, similar to the builtin commands, will navigate to the top-most directory of the repository and keep the subdirectory as a variable. As the helper is called from within the git-submodule.sh script, we are already navigated to the root level, but the path arguments are still relative to the subdirectory we were in when calling git-submodule.sh. That's why there is a `--prefix` option pointing to an alternative path which to anchor relative path arguments.
