yuicompressor for css throws error for some files - css

Question

i just tried using the yuicompressor for CSS. Works for most files, but for one it didnt, and gives me this error:
"C:\Program Files (x86)\JetBrains\PhpStorm 8.0.1\jre\jre/bin/java" -jar C:/nodejs/node_modules/yuicompressor/build/yuicompressor-2.4.8.jar style.css -o style.min.css

Caused by: java.lang.StackOverflowError

After these lines there are thousand errors.
I looked at another post here but it didnt fix it really. It said something about increasing the stack size(?), if thats the solution, how would i do that? google wouldnt give me any useful answere either.
thanks in advance.

Answer 1

To increase the stack size, you need passing -Xss option to java. Default is 512k, try increasing it, for example to -Xss2048k.
To do this, you either need to modify node_modules\yuicompressor\nodejs\cli.js accordingly, by adding args.unshift('-Xss2048k');:
var spawn = require('child_process').spawn,
fs = require('fs'),
compressor = require('./index'),
args = process.argv.slice(2);
args.unshift(compressor.jar);
args.unshift('-jar');
args.unshift('-Xss2048k');
...
and then specify a path to yuicompressor binary in a Program field of your file watcher (like C:\Users\My.Name\AppData\Roaming\npm\yuicompressor.cmd).
Or, set up your file watcher in a different way, using java as a Program:
Program: C:\Program Files (x86)\JetBrains\PhpStorm 8.0.1\jre\jre\bin\java.exe
Arguments: -Xss2048k -jar "C:\Users\My.Name\AppData\Roaming\npm\node_modules\yuicompressor\build\yuicompressor-2.4.8.jar " $FileName$ -o $FileNameWithoutExtension$.min.css
