stagit

static git page generator

This is a fork of https://git.codemadness.org/stagit

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+).
  • discount markdown
  • 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/${name}-$(echo "${t}" | tr '/' '_').tar.gz"
    test -f "${f}" && continue
    git archive \
        --format tar.gz \
        --prefix "${t}/" \
        -o "${f}" \
        -- \
        "${t}"
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.
  • Render README using discount markdown.
  • 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, the cache (-c flag) is a workaround for this in some cases.
  • Not suitable for large repositories with many files, because all files are written for each execution of stagit. This is because stagit shows the lines of textfiles and there is no “cache” for file metadata (this would add more complexity to the code).
  • Not suitable for repositories with many branches, a quite linear history is assumed (from HEAD).

    In these cases it is better to just use cgit or possibly change stagit to run as a CGI program.

  • 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 per commit.
    • File tree per commit.
    • History log of branches diverged from HEAD.
    • Stats (git shortlog -s).

    This is by design, just use git locally.
