superpat / gitfiles Goto Github PK

Gitfiles provides support for browsing Git repositories inside Acme.

It works like, and is based on, Netfiles[1]. Gitfiles presents read-only
access to a fake filesystem of files stored in Git. Gitfiles accepts paths
of the form

	/path/to/repo@tree-ish/repository/path

Where /path/to/repo is a valid Git repository, and tree-ish[2] is a valid
tree, commit or tag object name.

Gitfiles is best used with the following plumbing rules. The first rule
plumbs paths to Gitfiles; the second rule plumbs Git commits, formatted
so that their diff shows Gitfiles paths.

	kind is text
	data matches '[a-zA-Z0-9_\-./~{}@]+('$addr')?'
	data matches '((/[a-zA-Z0-9_\-./]+)@[a-zA-Z0-9_\-./~{}@]+)('$addr')?'
	data set       $1
	arg isdir      $2
	attr add       addr=$4
	plumb to gitfileedit
	plumb client Gitfiles
	
	type is text
	data matches '[a-zA-Z¡-�0-9_\-./]+'
	data matches '([0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f][0-9a-f])[0-9a-f]*'
	plumb start rc -c 'cd '''$wdir'''; root=`{git rev-parse --show-toplevel}; rev='''$1'''; {gitfileshow $rev} >[2=1] | nobs | plumb -i -d edit -a ''action=showdata filename=''$root/+$rev'
