lucs PerlJam: They appear to show up in the latest version. 12:05
Which page seems to be lacking for example? 12:06
(The latest version of the latex-tweaking branch, that is.) 12:32
PerlJam ah, so they do. 13:29
lucs Ok. 13:31
PerlJam: Can you try to build the 'page-dimensions' branch I just checked in? 16:04
I'd like your opinion on those dimensions.
The branch also handles a4/letter better.
PerlJam er, how do you specify a4 v. letter? I did "SIZE=letter make" and I get a book.letter.pdf, but it seems to be the same dimensions as book.a4.pdf 16:24
and they both appear to be letter sized
btw, some of the program listings seem to have no vertical whitespace immediately after them (like the first one in the basics chapter) while others seem to have a 1.5 lines of vertical whitespace immediately after them. 16:26
lucs Oh, the text should appear to be exactly the same, but it will be centered differently on the paper.
Yeah, I saw that spacing problem, it should be fixable. 16:27
The main difference for the page-dimensions branch is that the text is a lot narrower.
Do you thionk that's better?
think
PerlJam looks again
It's looks fine to me :) 16:28
lucs I prefer it narrower too.
Did you have trouble setting up your build environment? (I did, and I'm wondering whether the authors will too.) 16:29
PerlJam Not much trouble. I needed to apt-get a few things (ubuntu) and I was off and running. 16:31
lucs Cool.
PerlJam (and I did need to google which things those were as the package names were not obvious from the error messages I got) 16:32
lucs Should we consult with all the authors before we commit all this latex tweaking to master?
PerlJam I'm the wrong person to ask :) 16:33
lucs Hey, you're one of the authors :)
PerlJam I generally commit anyway since it's easy enough to undo or change later.
But I don't know what the feel is from the other authors
lucs I wouldn't want the authors to be stuck with something they can't build, unless they're ok with that. 16:34
PerlJam make it optional in the makefile and I don't think anyone would have a problem with it. 16:36
"make tweaked" could take a different path from "make"
document what's needed (of course) 16:37
lucs Actually, it's a lot more than tweaked if you think about it.
Without these LaTeX modifications, the rendering is a bit awful.
On the other hand, you're right, maybe there should be a "minimum" type version. 16:38
So the authors could at least get an idea of what it looks like.
I wonder if there should be a black&white version, for eventual printing... 16:39
PerlJam Every Tuesday there's a meeting of the Perl 6 minds on #phasers @1800 UTC (I think. I'm always forgetting the time). Most of the book authors are usually there. You could show up and ask questions and get some feedback. 16:43
lucs Good idea, thanks. 16:44
What's that channel usually for?
Ok, I just checked its topic :) 16:45
PerlJam I guess it's at 1900UTC 16:47
lucs Okie doke.
(With a bit of luck, I'll remember :-) 16:48
PerlJam or you could just hang out on #perl6 and ask the authors as they show up. Often times we're all there simultaneously. 16:49
lucs You're right, it's not like if there were dozens of you :) 16:50
Hmm... Maybe I should email 'em all.
PerlJam that'd work too
lucs Gotta go for now. TTYL. 16:52

lucs pronik```: Hi. 19:56
pronik``` lucs: hi 20:17
lucs pronik: Please have a look at the page-dimensions branch (a narrower presentation). 20:18
(And it fixes the a4/paper centering thing.)
pronik lucs: do you know where I can get a proper grammar for perl6 apart from STD.pm? 20:21
lucs Sorry, no :(
pronik moritz_: ping
moritz_ pronik: pong 20:22
lucs Until such a grammar is found, I suppose it'll make correct syntax highlighting hard, eh.
moritz_ perl6.vim is pretty decent
github.com/petdance/vim-perl
pronik moritz_: see, my point is this: since perl6 is explicitely a specification, one could just snap that specification, wherever that is, and build something with it, like a lexer for pygments, so that the one perl6 book in existence actually looks good ;) 20:24
moritz_ pronik: well, STD.pm is part of the spec, and it runs
pronik and this specification (EBNF, anyone?) is nowhere to be found :( 20:25
moritz_ and it is as close to EBNF as you can get. EBNF itself isn't good enough to parse Perl 6
if you can hook up external programs, getting a syntax hilighter based on STD.pm running is quite possible
in fact, there's one on CPAN already, which emits HTML 20:26
pronik pygments.org/docs/lexerdevelopment/
won't do with an external program :(
moritz_ :(
so, what's wrong with what we currently have, except for some stray newlines? 20:27
pronik those are not newlines
moritz_ but?
pronik look into source, those are legitimate lines which are misparsed by the perl5 parser :(
same for french quotes -- they even get highlighted as "parsing error" 20:28
moritz_ uh
pronik can be nicely seen in the operators chapter
and since pygments is used in a freaking lot of different web application, it might be nice of nice to provide a perl6 lexer
only one example: trac 20:29
any perl6 projects would certainly appreciate it
moritz_ no doubt about that
pronik so how big are the chances that if we write a lexer now that we'd have to change large parts of it later? 20:30
moritz_ the main syntax has stayed rather stable during the last few years 20:31
sometimes new quoting constructs get added, which freak out a parser that's not aware of them
but all in all it's more the builtins that change, or some small parts (like signatures)
pronik looks like perl6.vim could be reused almost completely -- they are using regexps too, like pygments 20:33
moritz_ actually perl6.vim uses a "wrong" approach. A Perl 6 parser needs to be predictive, whereas perl6.vim isn't, but is full (very good) heuristics :-) 20:34
but I don't know if pygment supports predictive parsing at all
pronik it depends, probably can be hacked to do anything 20:48
is pugs any good for studying?
moritz_ if you like haskell + parsec, sure 20:49
you can also study rakudo - after all it parses all of the examples
pronik I tend to forget that most part of rakudo is written in perl :) 20:52
moritz_ perl 6 even 20:55
bootstrapping hilarity :-)
moritz_ -> bed 20:56
