Re: Looking for help updating Perl 6 and Parrot part of Perl Myths talk
Tim (): I'd be grateful for feedback on any of the slides, but I'm especially interested in updates for: page 73 - Perl 6 implementations I've added Mildew, with links, to the SMOP line anything I should add / change / remove? What's the status of KindaPerl6? I think Elf could very well be added to those. page 77 - quantity of code writen in Perl 6 are there any other significant perl6 codebases? Again, Elf is a nice, large example. :) Counting up the lines of code in November: $ find lib -name \*.pm | xargs wc [...] 16185351 46558 total So 1600. But as always it depends on how you count: * Blank lines, comments... * We have another 1697 lines of tests. * We've factored out the module HTML::Template so that it sits in its own project, but those 500 lines of code could still be considered to be part of November, since they're run when November is. Depending on what you mean by significant, I'd also like to direct your attention towards SVG::Plot, proto, Gamebase, CSV, Druid, Form, HTTP::Daemon, Perl6::SQLite and Web.pm. All of those can be downloaded via proto. Anything else I should add, change or remove? I'm especially interested in verifyable metrics showing effort, progress, or use. Ideally graphical. Any interesting nuggets that fit with the theme will be most welcome. Moritz++ and I were talking about making a graph showing the increase of Perl 6 projects lately. Proto's project.list contains all the pertinent history, so half an hour with git-log and SVG::Plot ought to be able to produce something nice. If no-one else takes that as a hint, I might look at it soonish. :) // Carl
Re: [PATCH] Add .trim method
Jonathan (), Ovid (), Larry (): Can't say I really like the negated options though. They smell funny. Agreed, but ltrim and rtrim will disappoint Israelis and dyslexics alike. Suggestions welcome as I can't think of anything better. The .Net framework calls 'em TrimStart and TrimEnd (and has a Trim that does both). So maybe trim_start and trim_end if we wanted to take that lead... How about .trim(:start) and .trim(:end)? // Carl
Re: [PATCH] Add .trim method
Ovid (): =item trim our Str multi Str::trim ( Str $string ) Removes leading and trailing whitespace from a string. =cut I could optionally make the following work: $string.trim(:leading0); $string.trim(:trailing0); Setting leading or trailing to false (they default to true) would result in either leading or trailing whitespace not being trimmed. Setting both to false would be a no-op. Unless someone protests loudly, I can add this to S29, and I (or someone else with tuits) can implement it in Rakudo. // Carl

Re: [perl #60178] Commit r32189 breaks Parrot on Mac OS X 10.5.4
I pried r32189 apart to see which chunk of it breaks my compilation. The commit consists of two additions and one change. The two additions compile fine, but as soon as I make the change (attached), I can't compile. the-chunk.patch Description: Binary data
Re: [perl #60178] Commit r32189 breaks Parrot on Mac OS X 10.5.4
Is there anything else I can do to help track down the bug? To get Parrot to compile, I can still use the trick of downdating src/multidispatch.c to r32188, but this gives me 7 failing tests, not surprizingly.
Re: [perl #60178] Commit r32189 breaks Parrot on Mac OS X 10.5.4
Uh, and this might have something to do with the third last line of the failing make being gmake[1]: *** Deleting file `PGE.pbc'

Re: [perl #60178] Commit r32189 breaks Parrot on Mac OS X 10.5.4
Will (), James (): This will be difficult to diagnose unless we do see 'make' output, so please attach a file. Alternative, go to IRC #parrot and use 'nopaste' to post. To limit the verbosity, you could run make 2x and just send us the output of the second run, as presumably the interesting failure will be in that, and none of the pesky stuff that worked. Good suggestions. Here we go: http://nopaste.snit.ch/14409.
