#History

#Commits

import "@deckyard/git/" as git;

def repo as git.Repo init git.open(git.config(), ".");
for (def c in git.log($repo, "v1.0..HEAD", "", 0)) {
    io.printf("%s %s <%s>\n", $c.subject, $c.author, $c.authorEmail);
}
def tip as git.Commit init git.show($repo, "HEAD");

log(repo, rev, path, limit) starts at rev ("" for HEAD) or walks a range, keeps the commits touching path when one is given, and stops after limit (0 for all). Before the first commit it returns an empty list. Times are Unix seconds.

#Diffs

base and target pick what is compared:

def patch as string init git.diff($repo, "v1.0", "HEAD");
for (def s in git.diffStat($repo, "v1.0", "HEAD")) {
    io.printf("+%d -%d %s\n", $s.added, $s.removed, $s.path);
}
for (def ch in git.changes($repo, "HEAD~1", "HEAD")) {
    io.printf("%s %s\n", $ch.status, $ch.path);
}

stagedDiff is what commit would record. Renames are detected, and external diff programs never run.

#Files at a revision

A captured output stops at 16 MiB, and the call then fails rather than return part of it: readBytes and archive go through files and have no such limit, and log takes a limit.
