Regex – TextPad “find in files” not matching on simple OR regex

regextextpad

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?

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

Regex – Non greedy (reluctant) regex matching in sed

Neither basic nor extended Posix/GNU regex recognizes the non-greedy quantifier; you need a later regex. Fortunately, Perl regex for this context is pretty easy to get:

perl -pe 's|(http://.*?/).*|\1|'

Regex: matching up to the first occurrence of a character

You need

/[^;]*/

The [^;] is a character class, it matches everything but a semicolon.

To cite the perlre manpage:

You can specify a character class, by enclosing a list of characters in [] , which will match any character from the list. If the first character after the "[" is "^", the class matches any character not in the list.

This should work in most regex dialects.
