19:23 Joe_shmo: was afk there
19:23 Joe_shmo: anyways, I'm using it on linux
19:23 Joe_shmo: and I specify the language as #lang racket
19:23 Joe_shmo: and then I try a trivial structure: (make-posn 1 2)
19:24 Joe_shmo: and it returns an error: compile: unbound identifier in module in: posn-x
19:24 Joe_shmo: any ideas?
19:24 (join) jorick
19:24 rapacity: are you defining posn?
19:25 Joe_shmo: isn't posn a built in structure?
19:26 rapacity: not in #lang racket
19:26 jorick: if i set a string to some weird unicode like (define t "Ａ Ｂ Ｃ Ｄ Ｅ"), how do i get the "unicode value" from the things in the string? i want the code that i can type eg "\u1234"
19:26 rapacity: posn is defined in a few built-in langs/libraries though
19:26 Joe_shmo: oh...well that may explain things
19:26 Joe_shmo: gimme a sec

19:33 Joe_shmo: ok, I have a different question
19:33 Joe_shmo: say in gedit, in one file, I define a structure
19:34 Joe_shmo: lets call it struct
19:34 Joe_shmo: and then in the file I go (provide struct)
19:34 Joe_shmo: and then in another file, I "require" that first file with the definition
19:34 Joe_shmo: can I now use that structure?
19:38 rapacity: you'd need to use (provide (struct-out struct))
19:38 Joe_shmo: oooooooookkk
19:38 Joe_shmo: I was wondering why it wasn't working
19:38 rapacity: though you can provide specific functions
19:38 rapacity: instead of all the expanded struct functions
19:39 Joe_shmo: lets say I define x to be a struct structure
19:39 Joe_shmo: can I go (provide x) and then manipulate x in the other file?
19:40 rapacity: define manipulate ?
19:40 rapacity: you'd be able to create new x objects
19:40 Joe_shmo: like (struct-blah x)
19:40 Joe_shmo: you know what I mean?

19:40 rapacity: (struct thing (q w))
19:40 lewis1711: I don't know why all scheme module systems insist on doing it the racket way, tbh. assuming you're going to list every thing in the file you want to export.
19:41 rapacity: (provide thing)
19:41 rapacity: you won't have access to thing-q or thing-w
19:41 lewis1711: is it easier to code? i don't know. but i think keywords like "local-define" for stuff you don't want to export make more sense and makes code more readable
19:42 rapacity: you can just do (provide (all-defined-out))
19:42 rapacity: if you want to export everything out ?
19:42 lewis1711: yeah, but it's a rather redundant line of code IMO
19:44 rapacity: I think if the define-local idea was implemented you'd waste more characters with the -local everywhere
19:47 Joe_shmo: is there any way to just auto-indent everything you've highlighted in gedit?
19:48 lewis1711: rapacity: more characters, sure, but your intent in reading the code would be clearer
19:48 lewis1711: Joe_shmo: gedit can't really auto-indent, IME
19:48 Joe_shmo: IME?
19:48 lewis1711: in my experience
19:48 Joe_shmo: ooooo
19:48 Joe_shmo: but why
19:48 Joe_shmo: it just seems
19:48 Joe_shmo: so basic >_>
19:48 lewis1711: it can match previous indentation level
19:48 (quit) mwolfe: Remote host closed the connection
19:48 Joe_shmo: yeah I noticed that
19:49 Joe_shmo: that's all it does though lol
19:49 lewis1711: but schemers are indentation nazis
19:49 Joe_shmo: what do you mean?
19:49 rapacity: though with local-define you'd have to go through the whole file to know what's being provided or not
19:49 lewis1711: no problem in other languages that use it
19:49 rapacity: with the current provide, you can see it all in one spot
19:50 Joe_shmo: man this is so fail
19:50 Joe_shmo: even java has auto indent
19:50 lewis1711: yeah but java has a simple indentation scheme
19:50 lewis1711: schemes isn't
19:50 Joe_shmo: ok but scheme auto indents
19:50 Joe_shmo: rather
19:50 Joe_shmo: racket does

19:52 Joe_shmo: plus it's more complicated than that
