DESCRIPTION
Libgit is a wrapper around git9. It does not provide its own
git functionality.
Git functions that receive a list of files expect the last
element to be nil. All the file names are expected to be
relative to the repository root directory.
Most calls have an l-version which receives an array of
files instead of a va_list. The last element in those
arrays must be nil.
Initgit initializes libgit with an existing repository at
location dir. This will use git(1) to start the backend
filesystem.
Gitadd and gitrm add and remove files from the git file
tracking system by adjusting the INDEX9 file directly.
Gitcommit will use git(1) to commit the numbered list of
files. Arguments are forwarded unchanged, so it should be
possible to use wildcards like . or *. Msg will be used as
the commit message; it can be multiple lines.
Gitlog allocates the pointer pointed to by logs with as many
Gitlog structs as needed, plus an additional sentinel Gitlog
structure. It will fill this array with the last n commits
starting from commit or HEAD if commit is nil. The remain-
ing arguments can be a list of files used for filtering,
ending with nil.
The last Gitlog structure in the initialized array acts as a
sentinel and has its hash member set to nil. The array and
all its strings are allocated with malloc and should be
freed after using.
Freegitlogs can be used for that, which is recommended for
future updates.
EXAMPLE
Gitlogs *logs;
if (!initgit("/path/to/repo"))
sysfatal("%r");
gitadd("addfileA", "addfileB", nil);
gitrm("rmfileA", "rmfileB", nil);
gitcommit("adds and removes files\n\nfor demonstration only",
"addfileA", "addfileB", "rmfileA", "rmfileB", nil);
gitlog(&logs, 2, nil, nil);
for (Gitlog *l = logs; l->hash; l++) {
print("hash: %s\n", l->hash);
print("author: %s\n", l->author);
print("date: %s\n", l->date);
print("msg: %s\n", l->message);
}
freegitlogs(logs);
