README

stagit
======

static git page generator


Usage
-----

Make files per repository:

	$ mkdir -p htmldir && cd htmldir
	$ stagit path-to-repo

Make index file for repositories:

	$ stagit-index repodir1 repodir2 repodir3 > index.html


Install
-------

$ make
# make install


Dependencies
------------

- libgit2 (v0.22+).
- libc (tested with OpenBSD, FreeBSD, Linux: glibc and musl).
- C compiler (C99).
- make


Documentation
-------------

See man pages: stagit(1) and stagit-index(1).


Building a static binary
------------------------

It may be useful to build static binaries, for example to run in a chroot.

It can be done like this at the time of writing (v0.24):

cd libgit2-src

# change the options in the CMake file: CMakeLists.txt
BUILD_SHARED_LIBS to OFF (static)
CURL to OFF              (not needed)
USE_SSH OFF              (not needed)
THREADSAFE OFF           (not needed)
USE_OPENSSL OFF          (not needed, use builtin)

mkdir -p build && cd build
cmake ../
make
make install


Extract owner field from git config
-----------------------------------

A way to extract the gitweb owner for example in the format:

	[gitweb]
		owner = Name here

Script:

	#!/bin/sh
	awk '/^[ 	]*owner[ 	]=/ {
		sub(/^[^=]*=[ 	]*/, "");
		print $0;
	}'


Set clone url for a directory of repos
--------------------------------------
	#!/bin/sh
	cd "$dir"
	for i in *; do
		test -d "$i" && echo "git://git.codemadness.org/$i" > "$i/url"
	done


Update files on git push
------------------------

Using a post-receive hook the static files can be automatically updated.
Keep in mind git push -f can change the history and the commits may need
to be recreated. This is because stagit checks if a commit file already
exists. It also has a cache (-c) option which can conflict with the new
history. See stagit(1).

git post-receive hook (repo/.git/hooks/post-receive):

	#!/bin/sh
	# detect git push -f
	force=0
	while read -r old new ref; do
		hasrevs=$(git rev-list "$old" "^$new" | sed 1q)
		if test -n "$hasrevs"; then
			force=1
			break
		fi
	done

	# remove commits and .cache on git push -f
	#if test "$force" = "1"; then
	# ...
	#fi

	# see example_create.sh for normal creation of the files.


Create .tar.gz archives by tag
------------------------------
	#!/bin/sh
	name="stagit"
	mkdir -p archives
	git tag -l | while read -r t; do
		f="archives/$name-$t.tar.gz"
		test -f "$f" || git archive --format tar.gz "$t" -o "$f"
	done


Features
--------

- Log of all commits from HEAD.
- Log and diffstat per commit.
- Show file tree with linkable line numbers.
- Show references: local branches and tags.
- Detect README and LICENSE file from HEAD and link it as a webpage.
- Detect submodules (.gitmodules file) from HEAD and link it as a webpage.
- Atom feed log (atom.xml).
- Make index page for multiple repositories with stagit-index.
- After generating the pages (relatively slow) serving the files is very fast,
  simple and requires little resources (because the content is static), only
  a HTTP file server is required.
- Usable with text-browsers such as dillo, links, lynx and w3m.


Cons
----

- Not suitable for large repositories (2000+ commits), because diffstats are
  an expensive operation.
- Not suitable for repositories with many branches, a quite linear history is
  assumed (from HEAD).
- Relatively slow to run the first time (about 3 seconds for sbase,
  1500+ commits), incremental updates are faster.
- Does not support some of the dynamic features cgit has, like:
  - snapshot tarballs.
  - file tree per commit.
  - history log of branches diverged from HEAD.
  - stats (git shortlog -s).

  this is by design, just use git locally.
