Comment / Uncomment macro for Komodo ...

As an happy user of the SciTE editor I was missing this feature in Komodo Edit which by the way is an excellent product.

Comment/uncomment means that a "special" comment string is used, i.e. #~ for Python. If this string is present at beginning of line the macro removes it (uncomment); if not it is inserted (comment). Python and PHP only for now, and poor code for sure. Any help is welcome.

import logging

logger = logging.getLogger('macro')
h = logging.FileHandler("/tmp/somefile", "w")
logger.addHandler(h)

ke = komodo.editor
kd = komodo.document
kv = komodo.view
commentMap = {
    u'python': '#~ ',
    u'php': '//~ ',
    u'javascript': '//~ ',
    u'c++': '//~ ',
}

commentTxt = commentMap[kd.language.lower()]

def EVAL(stmt):
    res = eval(stmt)
    logger.error("%s --> %s" % (stmt, res))

def getLineNo(position=None):
    pos = position or ke.currentPos
    return ke.lineFromPosition(pos)
    
def getLine(lineNo=None):
    line = lineNo or getLineNo()
    eol = ke.getLineEndPosition(line)
    return ke.getTextRange(ke.currentPos, eol)

def vCHome(lineNo=None):
    if (lineNo is not None):
        ke.gotoLine(lineNo)
    
    ke.vCHome()
    if (getLine().strip() == ''):
        return
    
    if (ke.getTextRange(ke.currentPos, ke.currentPos+1).isspace()):
        ke.vCHome()
        
def doLine(lineNo=None):
    vCHome(lineNo)
    pos = ke.currentPos
    s = ke.getTextRange(pos, pos+len(commentTxt))
    
    if (s == commentTxt):
        ke.setSel(pos, pos+len(commentTxt))
        ke.replaceSel('')
    else:
        ke.insertText(pos, commentTxt)

komodo.view.setFocus()

try:
    pStart = ke.anchor
    pEnd = ke.currentPos
    lStart = ke.lineFromPosition(pStart)
    lEnd = ke.lineFromPosition(pEnd)
    if (lEnd < lStart):
        tmp = lStart
        lStart = lEnd
        lEnd = tmp
    for line in range(lStart, lEnd+1):
        doLine(line)
    
except:
    logger.error("Error", exc_info=True)

return
