Talks/Embedding an XHTML-template language into Perl \\ {image:pgh-pm-edsls.png|Title slide from my talk on EDSLs in Perl} I gave this brief talk for the {link:Pittsburgh Perl Mongers|http://pgh.pm.org/} on 2006-03-08. The talk is about embedding domain-specific languages into Perl. The running example is XHTML construction. You can download the slides here: {link:pgh-pm-edsls.pdf|http://community.moertel.com/~thor/talks/pgh-pm-edsls.pdf|img=none} Most of the ideas in the talk came from an earlier posting I made to the Perl Monks web site: {link:Embedding a mini-language for XML construction into Perl|http://perlmonks.org/?node_id=510000}. I would like to thank {link:Aristotle|http://perlmonks.org/?node_id=114691}, who contributed a nice syntax-simplification idea during the follow-up discussion. 1.1 The EDSL The EDSL looks like this: {code:none} html { head { title { "My grand document!" } }; body { h1 { "Heading" }; p { class_ "first"; # attribute class="first" text "This is the first paragraph!"; style_ "font: bold"; # another attr }; \# it's just Perl, so we can mix in other code for (2..5) { p { "Plus paragraph number $_." } } }; }; {code} The embedded language renders into XHTML: {code:xml} <html> <head> <title>My grand document!</title> </head> <body> <h1>Heading</h1> <p class="first" style="font: bold">This is the first paragraph!</p> <p>Plus paragraph number 2.</p> <p>Plus paragraph number 3.</p> <p>Plus paragraph number 4.</p> <p>Plus paragraph number 5.</p> </body> </html> {code} 2006-03-14 17:38:55.422 2006-03-14 17:18:49.729 Tue Mar 14 17:26:10 EST 2006
