Hi, considering the vast number of Operators and the like, I had the idea to implement a tool where you can enter a small piece of p6 syntax, and it explains what that might mean. (like a perldoc -f for operators/syntax elements instead of functions)
A short example: $ p6explain '[]' [...] can be * '[$expression]': access to one or more array elements if used as postcircumfix Example: @a[2]; # access the third element of an array @a * '[$operator]': the 'reduce' hyper operator Example: [+] (1, 2, 3); # gives 1 + 2 + 3 == 6 In a regex/rule: * '[$subregex]': groups the content of the brackets without capturing the match result of $subregex $ p6explain '*' * can be * '$exp1 * $epx2' the multiplication operator, forces numerical context onto its arguments. Example: say 2 * 3; * 'multi sub *method_name' exports the sub method_name into the global namespace In a regex/rule: * '$subregex*' is a quantifier meaning that the previous subregex may be repeated an arbitrary number of times, including zero times. Example: m/ [ab]* / matches '', 'ab', 'abab', 'ababab' # END OF EXAMPLE I have a few requirements in mind (not necessarily sorted by importance): * Free software: Artistic License 2, some BSDish or GPLish - I don't mind, as long as it's free ;) * Multiple frontends: I'd like to have at least a command line and a web frontend * Support for multiple (natural) languages. * Perhaps support for other programming languages as well * Should contain links/references to the official docs Now I'd like to hear your opinion: * Anything else that should go into the requirements? * Is it useful at all? * Is it possible to implement it satisfactory without building a p6 compiler? * Do you have a good idea for a project name? Any other ideas and comments are welcome as well. Cheers, Moritz -- Moritz Lenz http://moritz.faui2k3.org/ | http://perl-6.de/
