1 - XSLT
Since the syntax is XML (like the extensions tags) and XPath
similar to template syntax, although it's XML
that calls XPath, the
opposite of what we have) It would be reasonably consistent with
syntax. It also should also already be fairly well locked down, and
interface seems fairly clear - present template parameters as
parameters, and other magic words as an input document. We may just
a few simplifications to make it easier to use.
XSLT itself is a way too much locked down - even simple things like
substrings manipulation and loops aren't so easy to perform. Well, maybe
I am too stupid for XSLT but from my experience bringing tag syntax in
programming language make the code poorly readable and bloated. I've
used XSLT for just one of my projects.
Should be easy to write a parser for if needed, since the grammer is
and it should be relatively simple to lock down or extend as needed.
Deeply nested braces of lisp remind me of current MediaWiki parser.
Of course, those are both a bit more esoteric than
Perl is nice for getting useful results from short
code, if we're not
bothered by one parser with no grammer specification calling another
one. Tcl may
be a reasonable compromise; a less esoteric, imperative language which
used as an extension language.
