gh-140347: Use pyrepl's colorizer in IDLE #140337
Conversation

@terryjreedy What do you think about this approach in general? It is a cut/paste job with some minor fixup's to get tests passing, so it needs some cleaning up. We could also consider importing duplicated logic. This will also fix the reported issue, and probably a few more. |
|
cc @ambv you may find this use of your code interesting :-) |
|
I need to work on this a bit more, I ran the tests without gui. From manual testing it looks promising. |
|
Down to four errors, three are because the old colorizer would continue on errornous syntax, whereas tokenizing is much stricter. I added a line-by-line fallback to cover some test cases, but I think in general more complex fallbacks (maybe trying a few lines at a time?) are worth it, and so we would need to accept some differences with the old implementation. I will leave this till I hear more from Terry. |

This is a generator function, which returns a generator-iterator that yields ColorSpans. The class name need not be repeated.

General comments belong on the new issue. See questions there. |

Apart from this section and a few minor modifications above, it is the same logic as in Lib/_pyrepl/utils.py.
