Regular expression not working! Bug ?

Post by lemmeshowyou »

Hello

The following regex works if I test it on regex101. See screenshot

Code: Select all

^(?!.*(a|e))p.*\.pdf

If I use the above regex in evertything, I get 0 matches. However if I change it into one of the following regex then I get matches.

^(?!.*(a))p.*\.pdf
^(?!.*[ae])p.*\.pdf

So the tricky part is the

Code: Select all

(a|e)
Whats wrong ?

| in Everything means OR

Please escape | with double quotes:

regex:"^(?!.*(a|e))p.*\.pdf"



-or-

Enable regex from the Search menu, and search for:
^(?!.*(a|e))p.*\.pdf

Do you think Everything needs to change something to avoid encountering such a problem?

Maybe hint the user if the the regex does not start with a double quote. Or coloroize properties and values.

The quotes will not be required in Everything 1.5 as the regex: search modifier will eat the | character.

Please make sure Enable regular expressions is unchecked under the Search menu.

Please try removing the space after regex:

regex:^b.*
