resty-gitweb

A git web interface for Lua/OpenResty.

Requirements

Lua modules (Lua 5.1/LuaJIT 2.1.0/OpenResty LuaJIT compatible, accessible from Lua path/cpath):

Module	Description
lfs	Filesystem API
lyaml	Reads and parses YAML config files
puremagic	MIME type by content, used in blob rendering
etlua	Embedded Lua templating (for HTML rendering)

Other command line tools (installed on system path, accessible from shell):

Program	Description
md4c (md2html)	Renders GitHub flavored Markdown
highlight	Syntax highlighting in HTML format

Linkable Libraries (installed on system path, accessible with LuaJIT's C FFI):

Library	Description
libgit2	Linkable C API for Git

Using

1. Copy this directory with its scripts to a place OpenResty/nginx workers have access, such as /srv/[SITE]/resty-gitweb. (In reality it doesn't matter where, as long as it's accessible.)

2. Copy your config file (resty-gitweb.yaml) to /etc/[SITE]/resty-gitweb.yaml (or somewhere else)

3. Add the following near the top (main context, outside of any blocks) of your OpenResty/nginx configuration file:

# resty-gitweb configuration
env RESTY_GITWEB;          # Script won't run without this
env RESTY_GITWEB_ENV=PROD; # PROD for Production, DEV for Development. DEV by default.
env RESTY_GITWEB_CONFIG=/etc/[SITE]/resty-gitweb.yaml; # Wherever you put your configuration file

4. Add the following to the http block in your OpenResty/nginx configuration file:

lua_package_path "/usr/local/lib/lua/5.1;/srv/[SITE]/resty-gitweb/?.lua;;"; # Add resty-gitweb to your Lua package path
init_by_lua_file /srv/[SITE]/resty-gitweb/init.lua;  # Initialize modules for nginx workers

5. And in whichever location block you wish to serve content:

content_by_lua_file /srv/[SITE]/resty-gitweb/app.lua;

6. Reload OpenResty/nginx to update config

OpenResty or nginx?

Note that I use "OpenResty/nginx" instead of just OpenResty; while you can just install and use the pre-built OpenResty package, you could actually use nginx with only a few added OpenResty components. These are the only OpenResty components you actually need to compile to use this package:

nginx modules

• lua-nginx-module

Lua libraries

(run sudo make all install LUA_VERSION=5.1 for each)

• lua-resty-core
• lua-resty-shell
• lua-resty-lrucache
• lua-resty-signal
• lua-tablepool

Note that lua-nginx-module is the only nginx module that needs to be installed with nginx compatibility. The other dependencies just need to be installed on your Lua path/cpath. If you're compiling OpenResty components yourself, you may need to build them with OpenResty's branch of LuaJIT 2.1.0 instead of the original.

(The full OpenResty package has far more precompiled OpenResty components, so you may just want to use that if resty-gitweb isn't the only thing you want to use OpenResty for.)
