FROGGS | hi all | 09:18 | |
masak | hi FROGGS | ||
FROGGS | is there an easy way to glue apache2 and perl6 together? | 09:19 | |
masak | I know the allure of turning Perl 6 into "your language" is very strong... but I look at the 5d20 thing in the backlog, and it seems very quixotic to not just .roll given Die.new("5d20"); or something | ||
good design is knowing when to stop bending the language, and to bend a little yourself :) | 09:20 | ||
bonsaikitten | FROGGS: CGI :D | ||
FROGGS | :( | ||

this is method load_setting, but I don't know why that happens when running under apache2 | 09:45 | ||
hmmm, just spitting out an html snippet takes 0.9 seconds :/ | 09:46 | ||
lizmat | "perl6 is fast enough, except when it isn't" :-) | 09:47 | |
FROGGS | hehe, I hear TimToady saying it like that :o) | ||
masak | get off my lawn. I delivered web content using Rakudo Perl back in 2008. | 09:48 | |
it was slow as all that, but through various tricks we managed to bring the typical response time from 17 s to 1.5 s. | 09:49 | ||
lizmat | don't we have a Perl6 PSGI layer already ? | ||
masak | HTTP::Server::Simple claims to have PSGI support. | 09:50 | |
so yeah, there's no legitimate reason not to kill CGI. with fire. | |||
lizmat | FROGGS: fwiw, apache2 / mod_perl is on the way out with many outfits, including e.g. Booking | ||

FROGGS | that is a problem | ||
lizmat | ah, ok, I didn't know apache was a prerequisite | ||
sorry for the noise, then | |||
FROGGS | because the other ten webpages/vhosts would be sad if apache is not the listener enymore | ||
anymore* | |||
thanks anyway for the tips, I really appreciate it | 10:02 | ||
lizmat is bored running a 5 minute make, perl6 -e '01' cycle trying to find out where it gets into a RAM gobbling loop | 10:03 | ||
FROGGS | :/ | 10:04 | |
lizmat | I guess I should be glad it's only 5 minutes per iteration | ||
FROGGS | could be worse, yeah | 10:05 | |
hmmm, maybe I write my webapp in nqp :P | |||
lizmat | FROGGS: or run this on another port, and reverse proxy to it from apache2 | 10:11 | |
FROGGS | hmmmm, that sounds good | ||

FROGGS | well, not new, but I forgot about that right now :o) | 10:21 | |
I was thinking about a listener on another port a few days ago, and we have reverse proxies at work... | 10:22 | ||
but sometimes the connection between these is not properly established correctly in my head | 10:23 | ||

FROGGS: any suggestions? | |||
FROGGS is thinking | |||
lizmat | simplest case: my @a; @a[1..*] | ||
FROGGS | r: my @a; @a[1..*] | ||
camelia | ( no output ) | ||
FROGGS | lizmat: this only hangs on your box, right? | 11:55 | |
lizmat | in the method2sub branch | ||
FROGGS | do you have additional local changes? | ||
lizmat | nope | ||
FROGGS | k | 11:56 | |
lizmat | just debug statements that I just removed | ||
so double checking now, will tell you in about 4 mins | |||
FROGGS | k, building too | 11:58 | |
lizmat | yup, perl6 -e 'my @a; @a[1..*]' in method2sub as on github | 12:02 | |
hangs | |||
.tell jnthn in method2sub, my @a; @a[1..*] hangs because, most likely, the whatever cannot see the .elems of the object anymore | 12:04 | ||
yoleaux | lizmat: I'll pass your message to jnthn. | ||
FROGGS | lizmat: which candidate gets called, do you know that? | 12:06 | |
lizmat | I don't think the candidate gets called | ||
it seems to expect a QAST::WVal(Int) for the infix<..> | 12:08 | ||
I guess the WVal is not set up correctly | 12:09 | ||
looking at perl6 --target=ast -e 'my @a; @a[1..*]' | |||

that's why *-1 is the index of the last element of the array, for example, because it's .elems-1 | 13:21 | ||

Mouq | Wait, I don't think that's my fault... What is '\q' doing? | 17:25 | |
geekosaur thinks that thing above was not Mouq's fault at all but a longstanding rakudo weirdness (possibly related to mixing different representations in an error message) | 17:27 | ||
errr | |||
^different rep^different unicode rep | |||
notably, that looks a lot like utf32 being output as utf8 | 17:28 | ||
Mouq | That's my thought as well… | ||
moritz | \o | 17:30 | |

timotimo | i thought it kinda looked like stack data; like lots of small integers | ||

pmurias | it should | 18:11 | |
colomon | it's spec'd, yes. | ||
looks like it compiles, at least | 18:12 | ||
colomon would like to know why ISO 10303 defines all the keywords in lower case, but always uses them upper case. :\ | 18:13 | ||

I'll have my generated grammar capable of testing it shortly. ;) | |||

masak | colomon: yes, grammars use the same code. | 18:30 | |
colomon: there are not two engines, one running regexes and another running grammars. it's all the same code paths. | |||
timotimo | well, there's the NFA and the straight up regex matching, so *kind of* two engines, but not really | 18:33 | |

colomon | mind you, it hasn't successfully parsed anything yet | 18:53 | |
masak | colomon: did you consider writing tests for both the code generation and using the generated result to parse stuff? | 18:56 | |
colomon | masak: I did consider it | ||
masak | colomon: I tend to forget TDD in such situations, even when it's really appropriate. | ||
colomon | it's not really clear to me how to write effective tests for this. | 18:57 | |
In general, that is -- and in specific, at the moment I'm hand modifying the generated grammar to see what works | 18:58 | ||
I can confirm that :i works in grammars, btw | 18:59 | ||
I'm running Grammar::Tracer, and it's getting past there. | |||
masak | colomon: is parse($wsn).parse($input), $expected_output; | 19:00 | |
(or equivalent) | |||
colomon | the problem is, you can have multiple valid outputs for one grammar | ||
masak | oh, sorry, I meant | 19:01 | |
ok parse($wsn).parse($input1) | |||
lue | hello world o/ | ||
masak | not parse($wsn).parse($input2) | ||
lue! \o/ | |||
nok* | |||
colomon | oh, wait, I see, you're running parse on the output of the parser. that is an interesting notion, indeed. | 19:02 | |
masak | yes, that was my main point. | ||
treating the generated result as a black box, and just testing for its expected semantics. | |||
colomon | does that work? I assumed I'd have to write out a file, or at least call eval | ||
masak | that was the handwaving part. | ||
in these cases, I tend to write the ideal API client code first, and then the API ;) | 19:03 | ||

arnsholt | WSN sounds like another ideal place for slangs \= | 19:07 | |
Er, =) | |||
(Keyboard-layout-confusion strikes again) | |||
colomon | arnsholt: :) | ||
I'm not wildly optimistic about the prospects, just because it seems WSN is not really well-specified. | 19:09 | ||
19:10
SamuraiJack left
|
|||
masak | colomon: what about it doesn't feel well-specified? | 19:10 | |
colomon | Using p6 terminology, some rules want :sigspace and some don't, and there's no rhyme or reason I can see for it. | 19:11 | |
masak | oh, and that's why you're having trouble with "regex" vs "rule"...? | ||
colomon | yes, exactly | 19:12 | |
sergot | hi! o/ | ||
colomon | if you look at that one on the wikipedia page, you'll see that it makes no allowances for whitespace | 19:13 | |
meaning if you take it without :sigspace, it cannot parse itself | |||
but at the same time, if you add :sigspace everywhere, then identifiers can have spaces in them. | |||
also, it never defines "letter" or "character" | 19:14 | ||

gdeepi | i want a perl script ..is this channel not for that ? | 19:53 | |
masak | gdeepi: note the '6' at the end of '#perl6' :) | ||
diakopter | gdeepi: you probably have perl version 5.. | ||
FROGGS | and yes, that makes a huge difference :o) | 19:54 | |
gdeepi | ok am not sure act the diff ..if this question is not meant to b answered here .sorry abt that | ||
geekosaur likes how they joined both #perl and #perl6 but asked here instead of there | 19:55 | ||
colomon wonders what the answer is | |||
geekosaur also wonders what's wrong with youtube-dl | |||
gdeepi | yes i hv ver 5 but i guess i can upgrade it to 6 ! isn't it ? | ||
colomon | gdeepi: but no one has written a youtube downloader in perl 6. | 19:56 | |
gdeepi | ok got it | ||
colomon is not sure if there is one in perl 5 or not. | |||

masak | \o/ | 20:13 | |
colomon | turns out rule doesn't work at all, the grammar cannot ratchet. | 20:14 | |
so the first half is regex, and the second half is regex :sigspace | 20:15 | ||
(this is the huge ISO-10303 part 11 grammar) | |||
