Comments:
<0> Eh? It's just over there? :)
<1> you use that form when substituting (with tr or s), not with m for matching
<2> zshzn, I was interpreting your /s as '/s' not 's'
<3> merlyn: apple uses a different UK layout to IBM. it's evil. \ and # and " are all wrong
<1> oh, sorry
<0> option backslash... option bar
<0> Oh. UK.
<2> zshzn, no worries, sorry for my lack of imformation
<0> and that explains your continual cynicism as well.
<4> integral: Serves you right for using Apple keyboards ;)
<0> The apple keyboard basically comes built in to my laptops.
<0> not really much of a choice.
<3> bah, if I was really bothered I'd just pry off keycaps and write a custom layout
<2> I have to say it is pretty cool to get advice from someone that wrote the book one is reading at that very moment..very cool indeed
<0> well - I try to help when I can.
<0> I'm just waiting for a friend of mine to get here so we can go see the smoking movie
<0> I'm in Beautiful Downtown Burbank this week.
<5> with this regex i want to grab the url that is before the <img tag, but the string contains multiple urls and it takes all of them.. /<a href=\"(.+?\d+)\"><img/
<0> Ugh! use HTML::parser
<6> tech-: stop using regexes to parse html? :)
<0> don't parse html with regex.
<1> hehe
<0> that'd be HTML::Parser
<0> or XML::LibXML if you want to do xpath on HTML
<0> I find that to be Rather Cool
<3> use v6;
<2> merlyn, the files I am working on are html. Should I not use regex on them?
<5> what's that?
<3> The_Isle_of_Mark: regex stands for "regular" expression. "Regular" is a technical term that refers to what you can parse easily with them.
<0> parse HTML with an html parser, not regex.
<3> Unfortunately lots of languages, such as HTML and XML, have things that nest, and regular expressions can't handle nesting.
<0> regex to parse HTML require either very specific text, or very hard regex.
<2> gah, no wonder even after all the help in here it wouldn't work
<0> that's why we have specialized HTML parsers.
<3> regexps are fine for tokenising bits of html and so forth, but you need a stack plus code to control how the regexps get called, and so on. We call this a "HTML parser".
<5> well, i'm extracting some basic information. wlel, i'm setting up a crawling egine, which i have variables for each regex for each type of information i need to gather, each site i configure it's own regexes for
<7> perlbot calc 3*255
<8> 765
<2> can perlbot devide by 0?
<9> merlyn: you mean to tell me it's not a good idea to parse irregular input with a regular expression?
<9> merlyn: how absurd
<0> if you're pulling apart a table, there's HTML::TableExtract, etc
<3> HTML::LinkExtor for the common task of link extraction. And WWW::Mechanize for the common stuff done in a web browser.
<2> perlbot calc 1/0
<8> Bad Expression: Illegal division by zero
<9> anyway, you can parse html just perfectly with Perl regexes;)
<0> really? you have some pretty complex regex then
<9> It's just a bit pointless to do so
<10> uh, no.
<9> /(?{insert real html parser here})/
<3> $html = qr{<(\w+)>(??{$html})</\1>|[^<]*} # what's the problem?
<0> parse html with XML::LibXML = http://www.perlmonks.org/index.pl?node_id=538412
<0> that fails on <a href> ... :)
<3> it's not a *full* html parser, it tackles the main point of difficulty
<0> integral - you're distracting the newbies again.
<3> merlyn: it also fails on <a><b></b><c></c><d></a>
<0> True
<0> works better on XML than HTML
<7> GumbyBRAIN: YAY
<11> simcop2387: Yay! Plan9 install under qemu failed?
<0> the optional close tags make HTML kinda tough
<3> GumbyBRAIN: tell me more about plan9.
<11> integral: 9 More to get me going.
<7> merlyn: i'm getting to where my webcam automation works great the only problem i've got now is that some jerk with a laser pointer can blind it for 15 seconds
<0> That was just in a movie I watched!
<0> inside-man
<7> heh, i implemented specific "daylight detection" code so that the camera can know if its too light outside (still without considering time) and force itself to go to a lower exposure despite what the normal algorithm things
<5> perlbot eval return ' <a href="?b=1&c=101&d=0&orderby=&page=29">30</a> <a href="?b=1&c=101&d=0&orderby=&page=30">31</a> <a href="?b=1&c=101&d=0&orderby=&page=1"><img src="http://static.thepiratebay.org/img/next.gif"; border=0></a></td></tr>' =~ /\"(.+?)\"><img/;
<8> eval return ' <a href="?b=1&c=101&d=0&orderby=&page=29">30</a> <a href="?b=1&c=101&d=0&orderby=&page=30">31</a> <a href="?b=1&c=101&d=0&orderby=&page=1"><img src="http://static.thepiratebay.org/img/next.gif"; border=0></a></td></tr>' =~ /\"(.+?)\" isn't something I know about, tech-
<7> and to keep it from fighting itself i have to force it to wait some time
<5> eval return ' <a href="?b=1&c=101&d=0&orderby=&page=29">30</a> <a href="?b=1&c=101&d=0&orderby=&page=30">31</a> <a href="?b=1&c=101&d=0&orderby=&page=1"><img src="http://static.thepiratebay.org/img/next.gif"; border=0></a></td></tr>' =~ /\"(.+?)\"><img/;
<0> EEEEEK!
<7> tech-: its eval:
<0> and it probably won't take that much
<7> tech-: and don't do that
<1> heh
<3> *sigh* I'll get more sandbags
<11> Gumbybrain's url is at the topic.
<7> thinks*
<0> eval: scalar localtime
<12> merlyn: Return: Sat Apr 1 15:16:15 2006
<0> ahh... somewhere in central time
<3> I wish all timestamps included the timezone by default.
<0> that one can't
<0> larry described it to me
<7> integral: he told Shadda yesterday, "BQS - if you're reading this maybe you should stop talking to me?"
<0> he's just calling localtime(3)
<0> and it doesn't ahve the timezone info
<3> merlyn: include a script with perl to patch libc.
<0> that's not part of the interface
<13> integral: Brilliant!
<0> Oh yeah, apatch libc
<0> that'll go over well.
<2> CPAN is huge
<0> what if you don't have the source to libbc? :)
<14> Ah! It's merlyn!
<3> merlyn: *binary* patch, obviously.
<13> integral: Make sure perl won't install w/o the patch. In the business world it's called "leveraging your market power"!
<3> ew73: that's okay, this "perl" will only be certified to work with one specific system, of which only two were ever produced.
<13> integral: The prototype serves as a couch in a high-tech coffee shop in downtown Portland, right?
<0> Yes! Portland!
<0> I visit there sometimes!
<0> usually on the way between teh airport and my house
<13> merlyn: Speaking of, how cool would it be if Backspace replaced all the furniture with ancient Crays?
<15> are #'s the only types oc comments.. no /* */ for long sections?
<0> what is backspace?
<15> s,oc.of,
<3> No need for heating!
<7> GumbyBRAIN: BQS
<11> simcop2387: bot query syndrome - if you're reading "ctime(3)", or whatever comes up with '0.
<14> errr, you can use perldoc to do the equivilant of /* */ iirc, but I've never used it.
<3> errr: yes. There is also POD for "documentation", see perlpod.
<13> merlyn: It's where the hipsters and geeks 10 years younger than me go to pull out their iBooks, trade pirated music, play chess, and **** up the wifi.
<0> generally, just get a good scource code manager. :)
<14> oh I meant perlpod, not doc, sorry
<15> ahh thanks Squall`, integral
<3> /* */ unfortunately don't nest anyway. {- -} would be a much better reference to appeal to.
<0> ew73 - is that in portland somwherea/
<0> it's probably downtown or east side
<3> playing chess is *hip*?!
<13> merlyn: Yeah, downtown, on like 5th and Burnside.
<0> nothing cool on the west side
<1> chess is very hip
<0> Yeah, feh
<0> chess is for people far smarter than me.
<3> Squall`: I preprocess my C though M4 and perl!
<14> lol
<13> I frequently beat my roommate, who studies strategy and such. I just move the first piece that I see as a legal move.
<0> I use Template Toolkit instead of CPP!
<3> oooh, good idea!
<1> we should have a #perl chess tournament
<3> is there something like PerlTidy for C? indent maybe?
<14> yeah, indent I guess.
<14> or cb, I think is the older one.
<7> ew73: then he's not very good
<14> c beautifier
<13> simcop2387: I like to think that I'm a savant.
<10> "lint". indent is current, but it doesn't like the 1tbs.
<0> I was on a cruise ship with four chess grand masters a few months ago
<14> I wish other languages had a "splain" utility.
<13> Was one of them a giant computer by IBM?
<0> including the #1 ranked woman
<2> well damn....the pdaxrom for zaurus perl install doesn't have perldoc. WTF?
<0> I requested "one night in bangcok" in the disco, and a couple of the grandmasters got up and danced. :)
<13> merlyn: Was it unfortunate?
<0> Actually, they danced pretty well, for chess geeks
<3> gah, stupid radio
