This little script is for using checkboxes in ASCII files.

If you don't have a checkbox in the current line the script adds a " " at the current position. If you do have a checkbox it toggles its state.

from Npp import *
import string
import sys
# A simple helper script for using ASCII todo lists
# The basic implementation knows 3 different states
# [ ] To Do
# [x] Done
# [o] Currently not possible to do
#
# The script is able to toggle between this states. If 
# you want only two states or if you want more states
# just edit the checkboxes string list.
#
# If a line doesn't contain a checkbox the script
# just inserts one at the current position.
def nextElem(arr, curPos):
    if (curPos + 1 < len(arr)):
        return arr[curPos + 1]
    else:
        return arr[0]
checkboxes = ['[ ]', '[x]', '[o]']
curLine = editor.getCurLine()
curPos = editor.getCurrentPos()
curLineNr = editor.lineFromPosition(curPos)
strippedLine = curLine.lstrip()
insertChkBx = True
for i in range(len(checkboxes)):
    elem = checkboxes[i]
    if strippedLine.startswith(elem):
        curLine = curLine.replace(elem, nextElem(checkboxes, i), 1).rstrip('\n')
        editor.replaceWholeLine(curLineNr, curLine)
        editor.gotoPos(curPos)
        insertChkBx = False
        break

if(insertChkBx):
    editor.addText('[ ] ')
