问题
I've tried searching files for either/or word scenarios and they always fail to find any results in TextPad.
An example is trying to find something like summer|winter where I want to return any files that contain either the word "summer" or the word "winter".
This regex works fine in other programs like Notepad++. Why doesn't it work in TextPad?
回答1:
Textpad.com online release notes says that they fixed a bug in 7.0.7 related to this where they:
Reject "|" as a regular expression
回答2:
Textpad seems to use slightly unusual syntax for regex 'finds'. Read the TextPad help file for the details. Here is an example for finding a IPv4 number. It works with textpad v4.7.3 'Find' and 'Find in files'
[^0-9][0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}[^0-9]

On older versions It works with: \(summer\|winter\),
Escape (alt+92 backslash) before every paren and "or" carácter.

Using Textpad 6.x, I have to escape the or operator and it works:
summer\|winter
回答5:
Try (summer)|(winter): it could be reading it as summe(r|w)inter.
