Go-Yui

Go-Yui is a golang interface to Yui-Compressor, for minifying Javascript and CSS assets.

YOU MUST HAVE JAVA 1.4 (AT MIN) INSTALLED SINCE IT USES Yui-Compressor

Yui-Compressor GitHub page

#Getting started

The goal of this package is to be the most expressive as possible. You minify some CSS or JS from a file or a string to a file or a string. So the syntax is very clear about that.

After installing Go and setting up your GOPATH, create a golang file. ##To minify some CSS

package main

import (
    "fmt"

    "github.com/jstoja/go-yui"
)

func main() {
    yc := yuicompressor.NewYuiCompressor().Options(map[string]string{
        "javapath":  "/var/test/path/java",
        "jvmparams": "-Xms64M -Xmx64M"})

    output, err := yc.MinifyCss().FromString(fixture_css).ToString()
    // or
    // output, err := yc.MinifyCss().FromFile(example).ToString()
    if err != nil {
        panic(err)
    }
    fmt.Println(output)
}

##To minify some JS

package main

import (
    "fmt"

    "github.com/jstoja/go-yui"
)

func main() {
    yc := yuicompressor.NewYuiCompressor().Options(map[string]string{
        "javapath":  "/var/test/path/java",
        "jvmparams": "-Xms64M -Xmx64M"})

    output, err := yc.MinifyJs().FromString(fixture_js).ToString()
    // or
    // filepath, err := yc.MinifyJs().FromString(fixture_js).ToFile("example.min.js")
    if err != nil {
        panic(err)
    }
    fmt.Println(output)     
}

Then install the yui-go package using the command:

go get github.com/jstoja/go-yui

You just have to run it:

go run example.go

#Features

##Now

It:

  • Grabs the yui-compressor jar according to the package directory
  • Takes JAVA/JAR/JVM parameters to fit your environment
  • Takes a CSS string/stream/file and process it
  • Takes a JS string/stream/file and process it
  • Uses the yui-compressor jar

##In the near future

It'll:

  • Be able to use all options of yui-compressor
  • Integrated as a Martini plugin since I think this go-package is super-cool

##In the great future

I'd like it:

  • Rewritten using pure concurrent Go instead of using the lib
  • To be used as both as a package and a cli-tool

#Notes about this project

This is my first go-package and since I'm new to Golang, I would really appreciate all advices about this work.
