hello,
playing with <>, two questions came to my mind:
a) why isn't it "regular" ?
use Test;
ok < foo bar bang > ~~ List, "a list";
ok < foo bar > ~~ List, "a list";
ok < foo > ~~ List, "a list"; diag "actually a Str";
ok < > ~~ List, "a list";
not only it is an exception to a simple rule but it waste memorizable and short
way to write a 1 element list. as always with perl6, i trust the perl6
designers for having a very good reason and i'm curious: what is actually
this good reason for such a weird behave.
b) shortest way to hash ?
i used %(< class foo id bar >) in my code
https://github.com/eiro/p6-Rototo/blob/master/t/basic.t#L21
i know it sounds stupid but i'm very sorry not being able to write (and most
of all: read and edit)
%< class foo id bar >
which isn't allowed ... but perl6 let me cheat: i can define a %
operator working with an extra space
use v6;
use Rototo::html;
sub H (*@data) { join '', @data }
sub prefix:<%> ( List $l ) is tighter(&infix:<,>) { %(|$l) }
say % < id foo class bar >; # class => bar, id => foo
( % < id foo class bar > ).^name.say; # Hash
say H br :id<foo>, :class<bar>; # <br id="foo" class="bar"/>
say H br |% < id foo class bar >; # <br id="foo" class="bar"/>
say H p |% < id foo class bar >, "this is a good thing";
# <p id="foo" class="bar">this is a good thing</p>
this is working but raised 2 questions:
* if it was so easy, why isn't it in perl6?
[ ] i missed the good paragraph of the documentation ?
[ ] i'm going to do something very stupid ?
[ ] other, your answer here
* i just don't know way i need | in front of % ... it just works but for
me %() was enought and explicit on what i wanted to get. can someone explain ?
regards
