Re: [Boost-users] Boost.Regex - Match whole word

Hi All,

I'm developing my own grep tool and I would like to specify an option to match a whole word. Which mean, if I'm looking for 'main' I don't want to match 'mainVariation' but things like 'main(int' or 'one,main,two'. The equivalent of what you will find in any decent search tool :).

I look through regex documentation and didn't find anything about that. If it's not implemented, is it planned to be ? Or shall the Boost.Regex user handle this applying some pre-processing on the regular expression to perform such task ?

Correct, there's no compile time flag to alter this, but you can encase your regex in \<(?:expression)\> where "expression" is your original expression. John.
