Regex built from auto nb matchs 100000 search time 170.172ms But Let's Speed It Up Regex in one piece nb matchs 100000 search time 180.01ms The good news is that on my system, the result is slightly faster than before: Una excelente opción para resaltar los elementos de su diseño. What you can do instead, is use deduced type for the sub-expressions: using boost::proto::deep_copy Ĭonst auto hostname = deep_copy(+~(xp::set = ' ', '/')) Ĭonst auto path = deep_copy(!(*('/' > ~(xp::set = ' ')))) īe aware that the deep_copy is absolutely necessary to avoid dangling references to temporaries since you're naming the expressions now. Descarga gratuita de la fuente Xpressive Bold. Regular expressions can be written as strings that are parsed at run-time, or as expression templates that are parsed at compile-time. No you can't get around the function invocation / type erasure overhead of sregex instance, because the expression template has already been compiled. xpressive is an advanced, object-oriented regular expression template library for C++. This is particularly annoying because a main force of Xpressive is the ability to construct complex regexp from simplier one, which can be quickly become a nightmare if using pcre or equivalent.īut if it comes with such a performance cost, the benefit looks annihilated.ītw, is the library still maintained ? according to boost changelog, no change since boost 1.55 (11Nov 2013 !)

Std::string negative = "sdaoas dof jdfjo fds dsf http:/" If the expression is defined in one go, execution is around 6x faster than if the same regex is built from 3 sub regex. The inner regex participates fully in the match, back-tracking as needed to make the match succeed.Ĭonsider these 2 ways of defining a regexp matching an uri (probably sub-optimal and not 100%, but the point is not on this topic). 2 likes, 1 comments - Xpressive Designs (xpressivedesigns) on Instagram: 'FLYER DESGN Need a flyer or template Attention-grabbing, high-quality flyers to mar. The inner regex is invoked by the outer regex during pattern matching. It is as if the regex were embedded by value that is, a copy of the nested regex is stored by the enclosing regex. doi:10.1016/j.sbspro.2011.10.Using Boost Xpressive (static expression), I noticed that pattern searching is much slower when the expression is built from sub regexpression.ĭid I miss something ? or is it inherent with the design ?
