= ladici - The LADI Continuous Integration software

.WORK IN PROGRESS
[NOTE]
This is Work In Progress.

== Goals

 * Minimal dependencies
 ** lua
 ** luasocket
 ** fengari (optional, for the client-side scripting frontend)
 * IRC based LPC/RPC
 * no database. Use lua files for configuration. Use filesystem symlinks & hardlinks where a simple filesystem tree is not enough.

== Concepts

 * ladici HQ - the central machine/node
 * ladici factory - a machine/node (can be the HQ one) where lanes are hosted
 * ladici lane - a chain or DAG of rules & commands to be executed by ladici factories

In simplest case, ladici deployment consists of single machine/node running ladici. The process running HQ can also run a factory and is pre-configured so with one that runs lane to create tarballs from sources.

== Download (via GIT)

 * https://gitea.ladish.org/LADI/ladici[Upstream repo - self hosted]
 * https://github.com/LADI/ladici/[GitHub repo - cloud hosted]

== Usage

Running "./ladici hq" from source checkout will start the HQ node.
By default HQ node comes with a HTTP server listening at 127.0.0.1:8010 for read-only HTML server-side scripting generated view.

To run the client-side scripting in WWW browser with JavaScript:

 * Obtain a copy of "fengary-web.js". fengary-web-0.1.4 can be downloaded from https://github.com/fengari-lua/fengari-web/releases/download/v0.1.4/fengari-web.js
 * Copy fengari-web.js to the same directory that will serve ladici-fengari.html and ladici-fengari.lua
 * Setup web server to serve static content of the directory where ladici-fengari.html and ladici-fengari.lua and fengari-web.js reside and make ladici-fengari.html the default document.

== Configuring

Example of configuring the ladici http server to bind at 127.0.3.2 instead of 127.0.0.1

.~/.ladici
[source,lua]
----
-- -*- Mode: Lua; indent-tabs-mode: nil; lua-indent-level: 2 -*-
return {
--  mode = 'hq', -- default: 'hq'
  http_bind = "127.0.3.2",
--  http_port = 8010, -- default: 8010
}
----

For simple setups the above works good with /etc/hosts line like:

./etc/hosts
[source,txt]
----
127.0.3.2 ci.myproject.internal
----
