Hi Sebastien,
Thanks for your reply. I had seen the second link, which seems to suggest I can use lookbehinds: "Lookbehind assertions start with (?<= for positive assertions and (?<!
for negative assertions". PCRE definitely allows them as per the manual http://www.pcre.org/pcre.txt . However in practice it doesn't seem to work. I can use lookaheads: e.g if I make a rule like this in C.lang <context id="myregex" style-ref="myregexstyle"> <match>foo(?=bar)</match> </context> then apply a light blue colour, it results in this: http://i.imgur.com/RtdVtrm.png But if I try to use a lookbehind like this: <context id="myregex" style-ref="myregexstyle"> <match>(?<=foo)bar</match> </context> It doesn't work and breaks all the other colours: http://i.imgur.com/ThKBFsX.png which is quite strange!
