| 10:13 | <@AnnoDomini> | Can anyone tell me how one uses subroutine-private variables in Perl? |
| 10:13 | <@AnnoDomini> | I know there's the my keyword for them. |
| 10:14 | <@AnnoDomini> | But I'm unsure where I need to use it. Just at declaration? Every time I assign them? |
| 10:18 | < Vornicus> | Just declaration, I would assume. |
| 10:19 | <@AnnoDomini> | I'm not so certain, since Perl doesn't require declaration. Over in mIRC scripts, if you wanted a variable with any special properties, you had to state them every time you assigned it. |
| 10:21 | <@AnnoDomini> | Also, the if-then-else structures seem just as fucked as in mIRC. |
| 10:24 | <@AnnoDomini> | Ah, my mistake there. It's the substr actually doing its job. I'm used to the fucked up thing mIRC has. That's solved at least. :D |
| 10:27 | < Vornicus> | Or, rather, First Use. |
| 10:37 | | * AnnoDomini mutters darkly about string concatenation, which somehow doesn't want to work right. |

| 10:42 | <@AnnoDomini> | $result .= int(rand($diesize))+1 . ' '; // works fine |
| 10:43 | <@AnnoDomini> | $result .= ' ' . int(rand($diesize))+1; // omits every one of the spaces |
| 10:43 | <@AnnoDomini> | WTF? |
| 10:52 | < Stalker> | Perl not-so-secretly hates you. |
| 10:52 | <@AnnoDomini> | Mhm. |
| 10:53 | <@AnnoDomini> | Well, I have made my bot capable of parsing a single dice expression. :D |
| 10:57 | | * TheWatcher readsup |
| 10:59 | | RichardBarrell [mycatverbs@Nightstar-6846d4dc.cable.virginmedia.com] has quit [Connection closed] |
| 11:02 | < TheWatcher> | AD: you need to put the left seid of the . in brakets to preserve the space, ie: $result .= ' ' . (int(rand($diesize))+1); |
| 11:03 | < TheWatcher> | *side |
| 11:03 | < Vornicus> | tjat's the right side |
| 11:04 | < Vornicus> | And that seems like a ridiculous rule |
| 11:04 | < TheWatcher> | yeah, I only woke up about 10 minutes ago, give me some slack >.> |
| 11:04 | | Vornicus is now known as Vornicus-Latens |
| 11:13 | <@AnnoDomini> | TheWatcher: So, first use requires my, yes? |
| 11:20 | <@AnnoDomini> | TheWatcher: Also, how do I force output to the console? I'm using print, but it only shows up after exit. |
| 11:21 | < TheWatcher> | If you have 'use strict' or 'use vars' then you need my, our, or local before the first use. |
| 11:21 | < TheWatcher> | and print goes to stdout, which is buffered |
| 11:21 | <@AnnoDomini> | What if I don't use strict? |
| 11:22 | < TheWatcher> | if you need it to appear immediately, you either need to flush stdout (which means shenanigans with $|) or do 'print STDERR <whatever>' |
| 11:22 | < TheWatcher> | If you don't have use strict or use vars, you don't need my |
| 11:23 | <@AnnoDomini> | So any variables used in subroutines are by default private? |
| 11:25 | < TheWatcher> | yes |
| 11:26 | <@AnnoDomini> | $result = substr($result,0,length($result)-2).')'; // For some reason, this sometimes removes two last characters, and usually one. I want it to remove just one. |
| 11:28 | <@AnnoDomini> | No, wait. |
| 11:28 | < TheWatcher> | $result = substr($result, 0, -1).')' would work better then - if the last arg to substr is negative, it removes that many characters from the end of the string |
| 11:28 | <@AnnoDomini> | Oh. |
| 11:28 | <@AnnoDomini> | Thank you. |
| 11:29 | <@AnnoDomini> | How do I make newlines in print STDERR? |
| 11:29 | <@AnnoDomini> | It just treats them as literal \n. |
| 11:30 | < TheWatcher> | are you doing '\n' or "\n"? The former will be the literal, the latter gets interpreted |
| 11:30 | <@AnnoDomini> | Single quotes. |
| 11:32 | < TheWatcher> | yeah, single quoted strings are not subject to backslash or variable interpolation (except for \' and \\) |
| 11:33 | <@AnnoDomini> | TheWatcher: Could you /whois PainBot? I'm getting no output for some reason, and it worked last night. |
| 11:40 | < TheWatcher> | ircname : AD's Other DiceBot |
| 11:40 | < TheWatcher> | Seems to be there.. |
| 11:40 | <@AnnoDomini> | Okay, it's a problem with me, then. |

| 13:23 | <@AnnoDomini> | TheWatcher: I want to calculate the contents of a string, as if it was a mathematical expression. How do I do that? mIRC had $calc() for that purpose. |
| 13:38 | < TheWatcher> | eval |
| 13:39 | < TheWatcher> | eg: $foo = "1 + 1 + 1"; $res = eval($foo); |
| 13:40 | <@AnnoDomini> | Mmm. |
| 13:40 | < TheWatcher> | (if $foo is coming from user input, be very very careful to sanitise it, as eval allows you to execute arbitrary code) |
| 13:40 | <@AnnoDomini> | I see. |
| 13:42 | <@AnnoDomini> | $foo, in my case, is procedurally generated based on user input. |
