Predefined regex for Regex-function

sherman · 01-19-2020, 12:34 AM

If it doesn't already exist, would it be possible for regex functions to have a predefined rexep that populates the "Find:" field?

I find that the regex-functions I create need to be called with the correct regexp to work. Currently I store it as a comment in the function source, but that gets a bit tedious after a while.

doesn't already exist and while i have no problem with this, its not something I want to spend my time on either, so patches are welcome!

Thanks for the reply. If I can figure out how it all works, I might try and submit a PR some time.

Basically, would need to figure out how to obtain a variable, or run a function and update the "Find" field.

I'm assuming the place to start would be src/calibre/gui2/tweak_book/function_replace.py?

yeah and look in tweak_book/search.py
