Allow capture group substitution in case content

[Kindari]

This adds numeric and named capture group replacement to case content return data.

Example:

{exp:switchee variable="{segment_3}"}
    {!-- detect pagination, for example --}
    {case value="#^P(?P<page>\d+)$#|''"}
         We are on page #{switchee:page}
    {/case}
{/exp:switchee}

Looks good, but could you please apply your patch to the develop branch instead? That's the beta version of Switchee and will be the next stable release.

Many thanks

Hi, I did submit the request on the develop branch, as the top of this page says:

"Kindari wants someone to merge 1 commit into croxton:develop from kindari:develop".

Sorry that's what happens when you've been up all night :)

I can see a possible problem with this when using nesting, as the nested switchee tags start {switchee ...}

It won't trip up the tag pair regex but it could increase recursion.

Maybe we need to use different prefix text for the captured values or add a parameter to specify the prefix.

Thoughts?

[Kindari]

I would either change the prefix (if so configurable prefix would be preferable for users) or I would change the pattern to check against switchee:, the difference between the nested tag and the captured variable being a colon syntax.

[croxton]

Hmm, how about using parentheses {(page)} ?

I quite like that it echos the grouping syntax. What do you think?
