PW changes the output of external php class

[Roope]

Hi all!

I came across to strange issue today. I was testing the oyejorges Less.php class to parse my less assets and noticed that when I use it on PW template the output of class changes. When you use less percentage() function, on PW decimal mark changes from point to comma.

I've been using oyejorges Less.php class for some time now on different php apps and haven't noticed this kind of behaviour before. I'm totally lost here - where is it comming from and is it because of PW or Less.php? Any help is much appreciated!

My RTC details - code on php file outside PW and on PW template.

template:

<?php 

require 'site/modules/less/Less.php';   // test.php
require '../modules/less/Less.php';     // site/templates/home.php

$less = new Less_Parser();

$less->parse(" div { value: percentage(12.3 / 14.5); } ");

echo $less->getCss();

?>

output:

div { value: 84.82758620689656%; }   // test.php
div { value: 84,82758620689656%; }   // site/templates/home.php

What are the language settings of ProcessWire?

My guess is that maybe the locale is set different from PHP when you execute the Less script inside Pw templates.

Thanks Wanze! Lighting fast response and perfect answer!

This is multilingual site and I had finnish language by default for admin user so change back to english corrected output. You rock!

But now this leads to another question. I don't want my css output change for user language. It has to be same all the time or it's not valid. How can I prevent this change?

EDIT: ..or that makes me wonder isn't this more of a issue at oyejorges less class since it should worry about generating valid css and not to rely on any php locale settings..
