Re^5: Which internal DSL are there in Perl? (Domain Specific Languages

Time to quote chromatic :)

Not every API is a DSL.

Otherwise every class allowing cascading method calls would be a DSL.

It doesn't "read like a conversation" and it has a lot of redundant code, mainly the objects and arrows on the LHS.

The find examples you've listed are very well designed and could easily be structured in a better readable way, being extended with a DSL frontend.

here a very good discussion on it

I think I have to correct myself, since Path::Class tries to mimic XPath it should be qualified as DSL if XPath is a language.

My main problem is that I don't consider XPath to be a particularly good readable.

Both your CGI::HTML::Functions and Rex examples have more parent-language symbols that the two examples I gave My main problem is that I don't consider XPath to be a particularly good readable. wut. It's literally the same as a directory path, with the addition of subqueries (`[...]`) and simple comparison (`...=...`). I don't know of a simpler, more readable language.	[reply] [d/l] [select]
