Baconize
========


Compile/minify static site for production (with sourcemaps), auto-compiles files like app.coffee -> app.js.

Currently supports: LiveScript, babel, coco, coffee-script, dogescript, less, marked, myth, jade, node-sass, stylus, swig. To use any of these you must do npm install x as needed (where x is the name of the lib), baconize does not install them by default.

Example
-------

``javascript
var baconize = require('baconize');

var source = '/path/to/input/dir';
var target = '/path/to/output/dir';
baconize(source, target, [options]).then([successFn],[errorFn]);
`

How it works:
* Baconize will walk your source directory and process each file in /path/to/input/dir:
* If it can compile a file then it will compile it and output it to the target directory (with source map).
If it can't* compile the file then it will simply copy it to the target.

For example, if you have a coffeescript file in /path/to/input/dir/my-app/scripts/index.coffee then it will output the compiled file as /path/to/output/dir/my-app/scripts/index.js, and the sourcemap as /path/to/output/dir/my-app/scripts/index.js.map.

This library is designed for use alongside pingy-in-the-middle.


Options
-------

- compile (Boolean, default = true): should baconize try to compile files where possible?

- sourcemaps (Boolean, default = true): should baconize copy corresponding sourcemaps and source files for the minified/compiled files?

- minify (Boolean, default = false): should baconize minify javascript, css and html files? Will also minify post-compilation files.

- blacklist (Array): filter to blacklist files from being compiled or minifed. They will still be copied (without compilation/minifiction) unless they are negated using the fileFilter or directoryFilter options below. This option is useful for vendor directories (like 'bower_components') which already include the compiled versions of files. See Filters for more.

- fileFilter (Array): filter to include/exclude files to be copied to target. See Filters for more.

- directoryFilter (Array): filter to include/exclude directories to be copied to target, rules are applied to sub-directories also. Useful for directories like '.git'. See Filters for more.

- depth (Number): depth at which to stop recursing even if more subdirectories are found.

- exclusions (Object): Instead of blacklist, fileFilter and directoryFilter you can use the new exclusions api, this is undocumented for the moment.


Filters
-------

Filters take an array of glob strings. fileFilter and directoryFilter can be a whitelist or blacklist, by default they are whitelist but add the ! character before entries to turn them into a blacklist instead:

compileBlacklist: [ 'bower_components/*' ] copies the raw 'bower_components' directory instead of compiling files within the directory.

fileFilter: [ '.json', '.js', '.scss', '.jade' ] includes only* JavaScript, JSON, SCSS and Jade files.

directoryFilter: [ '!.git', '!node_modules' ] includes all directories except* '.git' and 'node_modules'.

See minimatch for some examples of glob strings.


Events
------

You can listen to chdir and compile-start and compile-finised events emitted by baconize.
`javascript
var bacon = baconize(source, target, [options]);

bacon.on('chdir', function(folder) {
// folder (string) is the current folder path that is being processed by baconize
});

bacon.on('compile-start', function(file) {
// compile has started on file (object).
//
// {
// name: 'typography.css',
// path: 'styles/typography.css',
// fullPath: '/Users/dave/Sites/my-site/styles/typography.css',
// parentDir: 'styles',
// fullParentDir: '/Users/dave/Sites/my-site/styles/',
// stat: {object} See: https://nodejs.org/api/fs.html#fs_class_fs_stats
// }
});

bacon.on('compile-done', function(file) {
// compile has finished successfully on file (object, see above).
});
`

Aborting while in progress
--------------------------

You can abort baconize while it's in progress.
If you do this then the promise will reject and the output directory will be removed.

`javascript
var bacon = baconize(source, target, [options]);

// abort baconize while in progress
setTimeout(function() { bacon.abort(); }, 10);

bacon.then(function(){}, function(err) {
// err (Error)
// {
// message: 'Manually aborted by user',
// code: 'ABORT'
// }
})
`

Try it out
----------
The easiest way to try this out is to clone the repo, cd into it and do:

`sh
npm install
npm run example
`

This will compile a basic demo site to examples/output`.
