00:13 askhader: Have any of you succsessfuly managed to use net/pop3 or net/imap ?
00:19 offby1: I think one of the PLT devs uses some racket app as his primary email, which suggests he successfully uses one or the other of those
00:20 askhader: I ought to write to the mailing list. Two lines of code straight from the documentation produce a regexp-match error from one of the source files.
00:22 offby1: indeed, that does sound like a mailing list type of question

00:31 mwolfe: Hopefully easy question here.  I'm trying to write a tcp-listener, but I want it to listen for connections and handle them on a different thread.  This means I need to pass the input-port and output-port into the function handling the connection.  Do I use call/cc to wrap up the arguments so that thread can all the no-arg function produced by call/cc?  Am I looking in the wrong direction?
00:41 mwolfe: Hmmm...I just may have been way overthinking that...nm.
00:44 mwolfe: I think I'm tired, that was a very simple question to solve...thanks though.

00:51 danking: So why is "mzlib/etc" a "Legacy Racket Library"?
00:51 danking: Is there another way to get `this-expression-source-directory' without using `define-runtime-path'?
00:54 Lajla: Assuming a purely functional language call/cc cannot be a function right?
00:54 Lajla: It has to be some special form or whatever because it's not referentially transparent, right?

05:05 heeki: Is there any reason not to change "define" to "def"?
05:14 Lajla: People like long names.
05:14 Lajla: I think def suffices.
05:14 Lajla: But hey
05:14 Lajla: I don't make the rules.
05:14 Lajla: Might as well make let local-block
05:14 Lajla: cons construct
05:14 Lajla: Why not pair really.
05:14 Lajla: I mean you have string, string? vector, vector? list, list? et cetera.
05:15 Lajla: Why not pair and pair?
05:15 Lajla: They already removed the original consp that was in use before that, why not make it complete.
05:16 heeki: Who likes long names though? Have you ever talked to somebody who actually prefers the longer name?
05:16 heeki: I think it's a significant thing that hinders the usability of the langauge
05:16 Lajla: Oh, jonrafkind isn't arouynd.
05:17 Lajla: Well, if you ever see him.
05:17 Lajla: I had endless debates with him about this.
05:17 Lajla: I think long names are indeed harder to read, he thinks the inverse.
05:17 Lajla: He says it makes inferring the function of a symbol hard if you use cryptic short names like 'strcpy'
05:17 Lajla: I think that you should never infer how it works from the name anyway and should just rtfm to begin with.
05:18 Lajla: In fact
05:18 Lajla: I think names should be kind of obfuscated in that way
05:18 Lajla: to force people toa ctually look up what stuff does before using it.
05:18 Lajla: Soooo many bugs have come from people just assuming how stuff works from the name and not looking it up.
05:19 Lajla: 'why doesn't my code work?' someone on stackoverflow asked,  'Well, because append doesn't mutate any of its arguments, it returns a new list!', someone on stackoverflow replied.
05:20 heeki: Is there a Racket function similar to emacs' describe-function?
05:20 Lajla: What does emoacs' describe-function do?
05:21 heeki: displays documentation associated with function.
05:21 heeki: Like if I want to know what a function does, I just press C-h f, type in the function name and hit enter.
05:21 heeki: To view documentation and a link to the source.
05:22 Lajla: I have no idea, I don't know it at the least.
05:22 Lajla: I think I had some discussion here once about the lack of docstrings or whatnot.
05:23 Lajla: This is because scheme users are academic elitist twits who have their Ph.D's stuck up their behind and don't care for practicality and enjoy bleeding fingers to death on long names. But yeah, we do understand call/cc.
05:23 Lajla: Call/cc is my chick magnet.
05:24 Lajla: I'm like 'Yo babe, can I buy you a drink, and even if it fails, don't worry, I used call/cc beforehand, I'll just jump back in and try anoher pickup line', and she's all over me.
05:28 heeki: I'm guessing there was another debate about 'call/cc' vs. callcc?
05:28 heeki: or ccc?
05:28 Lajla: No doubt.
05:29 Lajla: I think guille doesn't support call/cc and only call-with-current-continuation.
05:29 Lajla: I never need to cut my nails, they are trimmed just by typing that all day.
05:33 Lajla: I'm perfectly fine with stuff like this (def (vec . xs) (let* ((the-len (len xs)) (the-vec (mkvec the-len))) (let recur ((k 0) (xs xs)) (when (< k the-len) (vecset! the-vec k (car xs)) (recur (incr k) (cdr xs))))) the-vec)))

09:57 malky42: that is -- without me having to move the mouse and click the run icon?
09:59 askhader: does CTRL+T not work?
10:00 samth: heeki, (help function) at the repl
10:00 samth: or press F1 when your cursor is on `function'
10:01 samth: Lajla, call/cc is indeed not a pure function
10:01 malky42: oops, I think switched off the menus because I wanted to use the emacs-like keys. that's probably why CTRL+T is not work.  it does the emacs transpose thing.
10:02 samth: malky42, in that case, there's probably a separate key for "Run"
10:02 samth: malky42, go to Edit/Keybindings
10:02 samth: that should show you the current keybindings
10:05 malky42: okay i found it in the docs it's F5. that's great. btw the automatically closing ] and ) using just the ) is a great touch.
10:05 malky42: not having to press shift 0
10:05 askhader: malky42: What if you don't want a ] ?
10:05 askhader: Urg ignore me, I'm trolling.
10:05 malky42: hahaha
10:06 malky42: got me there
10:06 askhader: The answer is use non-drracket editor

15:33 jonrafkind: they are functional and lispish
15:33 jonrafkind: the jump from clojure -> racket is much smaller than java -> racket or c++ -> racket
15:36 carleastlund: Okay, so by "->" you mean "is similar to", is that correct?  It wasn't at all clear from your statement.
15:43 jonrafkind: i meant a sequence of languages you could learn without too much a gap between any two languages
15:44 carleastlund: Personally I would suggest reversing that list, and then possibly pruning it.
15:51 (quit) anRch: Quit: anRch
15:54 clklein: jonrafkind: If you still care, I think you probably can't express that in the `match' pattern language. You could use the (=> id) notation to bind "nevermind, it didn't match" procedure, test the length in the clause RHS, and call the procedure if they don't match.
