Feature or enhancement

  • Highlight the selected word.

  • Multi-line select by click the colon mark or click the space in indent.
  • Select escape character (\n, \xhh, \uxxxx, …).

Pitch

In the original IDLE, the logic that controlled the double-click selected text area was in file "~\tcl\tk8.6\text.tcl".

It is equivalent to select a regular expression that equal with "\w+" or "\W+". It help us double-click to select a whole parameter. It is better than nothing. But in my solution, it can do better.

Such as s.split('\n')[:ln], tk's auto selection will select ')[: and ('\, but this seems does not benefit to editing.

In my solution, I can double-click to select ('\n'), '\n', \n, and [:ln] (these were 3 types of match mode). I think this will help developers copy or cut code for what they want much more easier.

Notable things

  1. Considering that sometimes I want to copy text with brackets from comment text, So I use the text rule to match the bracket pairs. Unexpected selection may occur when existing escape characters.

  2. Highlighting the selected word will cause difference user experience at interface. Maybe not everyone like this feature. Do you have any suggestions?
