similar to: Named capture in regexp

I wanted to raise the possibility of improving strcapture performance in cases where perl = TRUE. I believe we can do this in a non-breaking way by calling regexpr instead of regexec (conditionally when perl = TRUE). To illustrate this I've put together a 'proof of concept' function called strcapture2 that utilises output from regexpr directly (following a very nice substring approach

completion is semi-broken in today's r-devel, and the reason seems to be some regular expression changes: > sessionInfo() R version 2.6.0 Under development (unstable) (2007-05-22 r41673) i686-pc-linux-gnu locale: [...] attached base packages: [1] "stats" "graphics" "grDevices" "utils" "datasets" "methods" [7]

Just a quick question or maybe a suggestion, is there a gem/plugin that will convert ruby regexp to javascript regexp?

The interpretation of regular expressions with repetition quantifiers in the 'gregexpr' function seems to have changed between R Version 2.2.0 and 2.3.0. The 'gsub' function, however, gives the same results in R Versions 2.2.0 and 2.3.0. Below is an example that demonstrates the version differences of the 'gregexpr' function. I am not sure whether this new behavior is

I notice in recent commits that a number of these have been added: /\[(\d+)\]/.freeze I thought that Regexps are immutable. Furthermore, Regexp literals don''t generate a new object each time they are encountered: irb(main):001:0> 3.times { puts /\d+/.object_id } -605707646 -605707646 -605707646 => 3 irb(main):002:0> Unlike strings: irb(main):002:0> 3.times { puts

Hi, I''m looking through the Merb::Routing code and I''ve found a regexp that I can''t figure out how it works. Merb::Router::SECTION_REGEXP #=> /(?::([a-z*_]+))/ It takes a route definition string, like "/products/:model/:id" and extracts the "model" string on the first pass, and later the "id" string. Can anyone shed some light on

What are your opinions on pcre vs regexp for header_, body_, and mime_checks in Postfix? I looked at the regexp_table and prce_table man pages, and see almost no difference other than the available flags. Miark

How would I use a regular expression to eclude an email address? I''m using validates_format_of :username, :with => :message => "Your username cannot be an email address." What is the expression to use after "with: =>" to exclude an "@"? -- Posted via http://www.ruby-forum.com/.

There was an old email thread from the end of January 2006 discussing regular expressions for matching URLs. I took some of the sample expressions and tweaked them a bit to the point where I think they are pretty useful. They pass all of my tests anyway. :-) For a reminder, here''s a sample message from that thread. My code is below it. On Jan 26, 2006, at 5:28 AM, Nathaniel S.

Hi, I''ve been using the rassmalog static blogging engine and have encountered a stack overflow inside the redcloth regexp matcher.

Running the following line will generate it (I''ve attached the YAML/redcloth file to this message). $ ruby -ryaml

Hello, I noticed (due to a recent post by Martin Honnen to clp) that Element.Class uses wrong regexps for its operations. E.g., Element.Class.has() will find "classA" in "classA-foobar" I also changed the interface of .has() to the more general one used in .has_any() --- util.js.old 2005-08-21 19:18:40.000000000 +0200 +++ util.js 2005-08-21 19:31:42.000000000 +0200 @@
