Automate Eclipse “Yui Compressor…”

问题


Eclipse PDT has this handy built-in Yui Compressor in the context menu for files. But when building a webapp that uses multiple such files, it becomes tedious to compress the files manually after each update. It doesn't even remember what files compress to which filenames, so you have to enter that again.

Is it possible to automate this process easily within Eclipse, so you can click on "build" or something and all specified files will be compressed to their targets?

There is really a vacuum concerning documentation about this Yui feature in Eclipse.

I am using Eclipse Indigo 3.7.0 with PDT 3.0.0.v20110516-11, but both PDT and the Yui option have remained pretty similar since Galileo

-update-

Automation solutions, not Eclipse-native but close:

  • GNU make makefile

    %-min.js: %.js
    ${java} -jar ${compressor} $< -o ${<:.js=-min.js}

  • Windows Batch

    FOR %f IN (*.js) DO java -jar yuicompressor.jar %f -o deploy\%f

  • Linux Shellscript

    ls -1 *.js | awk '{printf("java -jar yuicompressor.jar %s -o deploy/%s",$1,$1)}' | /bin/sh

  • ANT file

    See here: http://www.ubik-ingenierie.com/ubikwiki/index.php?title=Minifying_JS/CSS
    How do I paste html/xml here?

Well, I actually downloaded the jar and created an ANT task to to CSS and JS compression. I work on Tomcat, so it includes tasks to upload stuff, clean work/ directory and things like that. Hope it helps.

回答2:


You can also batch-minify using Node.js. However, this option is only for Linux users (for now).

Every time some software package is horribly lacking a convenience (Eclipse) or a builder batch format is just crazy (ANT), someone clever comes along and creates something awesome.

In this case,

  • node-minify

which is awesome.

Just thought I'd update this question and add the answer.

You can select and "build" js/css resources by configuring and adding an External Tool with a batch (for Windows users).

Step1: Add "yuicompressor" and "minify.bat" (given below) to your project.

Step2: Configure an External Tool named "Minify" (Run -> External Tools -> External Tools Configurations).

Step3: Select the resources (js/css) or the directory that contains them, and click "Minify". The js/css files will be deployed to the sibling "min" directory.

(minify.bat)

@echo off

set target=%1
set yui=%2\WebContent\build\yuicompressor\yuicompressor-2.4.8.jar

:: %1 selected resource
:: %2 current project

:: dir
if exist %target%\ (
  cd /d %target%
  mkdir min 2>nul

  for %%f in (*.js *.css) do (
    echo Minifying "%%~ff"
    java -jar %yui% %%f -o min\%%f
  ) 

  goto end
) 

:: .js/.css
set pathNoExt=0
for /f %%i in ('dir /b %target%') do set pathNoExt=%%~ni

if not %pathNoExt%==0 (
  cd /d %~dp1
  mkdir min 2>nul

  for /f %%f in ('dir /b %pathNoExt%.js %pathNoExt%.css') do (
    echo Minifying "%%~ff"
    java -jar %yui% %%f -o min\%%f
  )
)

:end
echo Minified
