I am in need of a library to parse/encode/decode URLs. A quick look through the boost tree doesn't yield any obvious candidates.
That would be a most welcome addition. It doesn't have to be anything as complex as Boost.Filesystem. Something like Python urlparse might be enough for most use cases.
Before I dive into writing my own, does anyone have any pointers/recommendations?
In the meantime, you can use Boost.Regex or Boost.Xpressive. According to http://www.faqs.org/rfcs/rfc2396.html a suitable regex is the following: ^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))? if $n are the groups produced by the regex, the parts of the url are as follows: scheme = $2 authority = $4 path = $5 query = $7 fragment = $9 There is also an example in Boost.regex using token iterators, see http://boost.org/libs/regex/doc/examples.html (search for "url").
