My regex (PCRE):
\b([\w-.]*error)\b(?:[^-\/.]|\.\W|\.$|$)
is a match (the actual match is surrounded by stars) :
**this.is.an.error**
**this.IsAnerror**
**this.is.an.error**.
**this.is.an.error**(
bla **this_is-an-error**
**this.is.an.error**:
this is an (**error**)
not a match:
this.is.an.error.but.dont.match
this.is.an.error-but.dont.match
this.is.an.error/but.dont.match
this.is.an.error/
/this.is.an.error
for this sample: /this.is.an.error
I can't manage to have a condition that will reject the whole match if it starts with the character /.
every combination I've tried resulted in some partial catch (which is not the desired).
Is there any simple or fancy way to do that?
You can try to add lookabehinds at the beginning instead of a word boundary:
(?<!\/)(?<=[^\w-.])([\w-.]*error)\b(?:[^-\/.]|\.\W|\.$|$)
Explanation:
(?<!\/) - negative lookbehind assuring there is no / before the first character;(?<=[^\w-.]) - word boundary implementation taking into account your extended definition of characters accepted for a word [\w-.];
