LESS support (Python Script)

[Dragon Chuang]

Open LESS file with Notepad++ and auto compile when file saved.

Environment:
Windows 7
Notepad++ 6.5.5
Python Script 1.0.4.0
node.js
Lessc

:::python

# Just in case, we'll clear all the existing callbacks
notepad.clearCallbacks([NOTIFICATION.FILEOPENED])
notepad.clearCallbacks([NOTIFICATION.FILESAVED])

class LessFileHelper:

    # Define the function to call just after the file is opened
    def fileOpened(self, args):

        bufferID = args['bufferID']
        filename = notepad.getBufferFilename(bufferID)

        if filename[-5:] == '.less':
            notepad.activateBufferID(bufferID)
            notepad.setLangType(LANGTYPE.CSS)
            editor.setProperty('lexer.css.less.language', '1')

    # Define the function to call just after the file is saved
    def fileSaved(self, args):

        bufferID = args['bufferID']
        filename = notepad.getBufferFilename(bufferID)

        if filename[-5:] == '.less':
            cmd = r'cmd /c %APPDATA%\npm\lessc.cmd "{0}" > "{1}.css"'.format(filename, filename[:-5])
            console.write(cmd + "\n")
            console.run(cmd)

lessFileHelper = LessFileHelper()

# ... and register the callback 
notepad.callback(lessFileHelper.fileOpened, [NOTIFICATION.FILEOPENED])
notepad.callback(lessFileHelper.fileSaved, [NOTIFICATION.FILESAVED])

[Dragon Chuang]

Update: add -s option to lessc, or notepad++ will hangs at lessc compile error.

:::python

cmd = r'cmd /c %APPDATA%\npm\lessc.cmd -s "{0}" > "{1}.css"'.format(filename, filename[:-5])

This implies you have %APPDATA%\npm\lessc.cmd, which is in the "Environment" that I didn't read.
