The PyWin editor that comes with the Windows distribution is a great little
workhorse. If you have used it you perhaps notice how it intelligently works
with spaces and indentation, e.g. after typing the word 'pass' and pressing
enter it dedents one level as you would probably desire. It also strips
trailing space from every line that you enter...unless that line contains ONLY
space.
The following modification to the AutoIndent.py file in the
pythonwin\pywin\idle directory makes the editor strip all trailing space, even
if that's all a line contains. With this modification, no line that you enter
with the PyWin editor will ever contain trailing space (unless you purposely
add it to the end of a line but then don't press <enter>).
Search for the word "inject" which appears only once in the file and add the
line as indicated below:
if i == n:
# the cursor is in or at leading indentation; just inject
# an empty line at the start
text.delete("insert - %d chars" % i, "insert") <== add this line
text.insert("insert linestart", '\n')
return "break"
This little modification is going to make my editing life less error prone as I
work on a project that checks for trailing whitespace. Maybe it will be useful
to someone else.
