Plugin request: Less CSS converter

[firefusion]

It would be great if I could convert LESS to CSS with a single command. http://lesscss.org/

EDIT: Looks like there is a simple windows command line app http://www.dotlesscss.org/. See documentation. So making a plugin should be very simple.

Looks like there is a Textmate bundle...

For a quick solution for ST1.4 take a look at this thread viewtopic.php?f=6&t=1267.
For ST2 not implemented but you can vote for it at the link at the bottom of the thread.
You could probably create a build system for this as well.

My first plugin - I'll add it to github @atomi when time permits.
Also, this is my first time playing with python.

Comments welcomed.

Code: Select all

import sublime, sublime_plugin, subprocess, os

class CompileLessOnSave(sublime_plugin.EventListener):
   def on_post_save(self, view):

      if not view.scope_name(0).strip().endswith('source.css.less'):
         return

      if os.name == "nt":
         startupinfo = subprocess.STARTUPINFO()
         startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW

      process = subprocess.Popen(('dotless.Compiler.exe','-m',view.file_name()),
      stdin=subprocess.PIPE, stdout=subprocess.PIPE, startupinfo=startupinfo)
      print('Compiled ' + view.file_name())


Thanks to adzenith btw and Default/exec.py

I get this error

Code: Select all

I get this error

Change this line:

Code: Select all

         if not view.scope_name(0).strip().endswith('source.css.less'):


to this:

Code: Select all

      if not view.scope_name(0).strip().endswith('source.css.less'):


In python indentation is important. The two ifs have to line up.

Thanks for your help. Ok, now I get this error after saving the change...

Code: Select all

Traceback (most recent call last):
  File ".\sublime_plugin.py", line 29, in reload_plugin
  File ".\CompileLessOnSave.py", line 1, in <module>
    class CompileLessOnSave(sublime_plugin.EventListener):
NameError: name 'sublime_plugin' is not defined

It doesn't output a css file on save.

I have dotless.Compiler.exe set in the system path as it does work.

I'm sorry I forgot to copy over the imports

Code: Select all

import sublime, sublime_plugin, subprocess, os

class CompileLessOnSave(sublime_plugin.EventListener):
...

Great! That works

Anyway I could get "sheetsheet.css.less" to compile to the name "sheetsheet.css" and not "sheetsheet.css.css"?
