A buildout recipe to compile javascript with the Google Closure Compiler
Project description
Compress javascript files using the Google Closure Compiler
Usage
Minimal buildout config example:
[buildout] parts = closure-compile [closure-compile] recipe = c2c.recipe.closurecompile compiler = path/to/closure-compiler.jar level = SIMPLE_OPTIMIZATIONS source_map = foo/bar.map externs = externs/a.js externs/b.js input = foo/bar.js output = foo/bar.min.js output_mode = compiled compiler_flags = --generate_exports
Where:
compiler: The location of the compiler jar file.
level: The compilation level: WHITESPACE_ONLY, SIMPLE_OPTIMIZATIONS or ADVANCED_OPTIMIZATIONS. Default is WHITESPACE_ONLY.
source_map: Path to the source map file. Optional.
externs: A list of optional externs files.
input: The files to compress separated with spaces. The path can be absolute or relative to the buildout directory. These files are also used to calculate the dependencies in addition to the namespace option.
root: The list of paths that should be traversed to build the dependencies.
namespace: One or more namespaces to calculate dependencies for.
output: The path to the minified file.
output_mode: The type of output to generate from this script. Options are “list” for a list of filenames, “script” for a single script containing the contents of all the files, or “compiled” to produce compiled output with the Closure Compiler. Default is “compiled”.
compiler_flags: A space seperated list of additional compiler flags for the Closure Compiler. They are passed to the compiler as specified. Optional.
depswriter
Writes dependency files with DepsWriter.
Minimal buildout config example:
[buildout] parts = depswriter [closure-compile] recipe = c2c.recipe.closurecompile:depswriter root_with_prefix = myproject ../../myproject ../source/ ../../../../source/ output = path/to/deps.js
Where:
root_with_prefix: A list of paths and prefixes.
output: The path to the dependency file, can be absolute or relative to the buildout directory.
Note that the root and the path_with_depspath options from the original depswriter.py script are not yet supported.
Getting the jar
To automatically download and unzip the compiler from Google, you can use the hexagonit.recipe.download receipt:
[buildout] parts = closure-compile [closure-compile] recipe = c2c.recipe.closurecompile compiler = ${download-closure-compile:destination}/compiler.jar ... [download-closure-compile] recipe = hexagonit.recipe.download url = http://closure-compiler.googlecode.com/files/compiler-latest.zip
