reggae-js

A javascript interface / front-end to the reggae meta-build system.

Installation

npm install -g reggae-js

It has to be installed globally so that the reggae_json_build.js executable is available. However, and because of this, require will fail to find the library portion so set the NODE_PATH environment variable to where npm installed it (.e.g. /usr/lib/node_modules/reggae-js/lib).

Usage

This package makes available a few classes and functions that allow the user to write build descriptions in Javacript using node-js. It is essentially the same API as the D version but in JavaScript syntax. A simple C build could be written like this:

var reggae = require('reggae-js')
var mainObj = new reggae.Target('main.o', 'gcc -I$project/src -c $in -o $out', new reggae.Target('src/main.c'))
var mathsObj = new regage.Target('maths.o', 'gcc -c $in -o $out', new reggae.Target('src/maths.c'))
var app = new reggae.Target('myapp', 'gcc -o $out $in', [mainObj, mathsObj])
exports.bld = new reggae.Build(app)

This should be contained in a file named reggaefile.js in the project's root directory. Running the reggae D binary on that directory will produce a build with the requested backend (ninja, make, etc.)

Most builds will probably not resort to low-level primitives as above. A better way to describe that C build would be:

var reggae = require('reggae-js')
var objs =  reggae.objectFiles({flags: '-I$project/src', src_dirs: ['src']})
var app = link({exe_name: 'app', dependencies: objs})
exports.bld = new reggae.Build(app)
