Assetgen Description

Asset generator for modern web app development Assetgen is intended as a replacement for the various ad-hoc scripts that often get written to build/manage JavaScript/CSS files.The tool is driven by the configuration you specify in an assetgen.yaml file, e.g.# Example assetgen.yaml configurationgenerate:- js/base.js: source: - %(AMPIFY_ROOT)s/third_party/jslibs/json.js- js/app.js: source: - static/js/Models.coffee - static/js/Views.coffee - static/js/Maps.coffee uglify: - --define-from-module - consts profile.dev: uglify: - --define-from-module - consts-dev- gfx/*: source: static/gfx/* type: binary- css/site.css: source: - raw: | // Public Domain (-) 2011 The Ampify Authors. // See the Ampify UNLICENSE file for details. - static/css/site.sass depends: - static/css/*.sass - static/gfx/* bidi: true embed.path.root: static embed.url.base: /.static/prereqs:- static/js/consts.js: source: static/js/consts.coffee compressed: false- static/js/consts-dev.js: source: static/js/consts-dev.coffee compressed: falseenv: NODE_PATH.prefix: static/jsoutput.directory: appengine/staticoutput.hashed: trueoutput.manifest: appengine/assets.jsonprofile.dev: css.compressed: false js.compressed: falseYou can even control which config options gets used by specifying the --profile parameter. This will override default values with the values specified for the given profile. So, in the above example, specifying --profile dev will use all the profile.dev options.And, finally, you can specify custom handlers for assetgen to call when generating a file of a given type. For example, to override the builtin js handler with one which just lower-cases all the source content, create your extension, e.g. kickass-extension.py:class KickassAsset(Asset): def generate(self): content = ''.join(read(source).lower() for source in self.sources) self.emit(self.path, content)register_handler('js', KickassAsset)Then run assetgen with the --extension path/to/kickass-extension.py parameter specified.UsageUsage: assetgen Note: If you don't specify assetgen.yaml file paths, then `git ls-files *assetgen.yaml` will be used to detect all config files in the current repository. So you need to be inside a git repository's working tree.Options: -h, --help show this help message and exit -v, --version show program's version number and exit --clean remove all generated files --debug set debug mode --extension=PATH specify a python extension file (may be repeated) --force force rebuild of all files --profile=NAME specify a profile to use --watch keep running assetgen on a loop
