09:57 Yann1: Hi, im trying to use define-syntax but it doesn't work as expected. Does somebody knows what the problem is? http://pastebin.com/Le5xq3eA Im want a syntax to make easy recursive lambda calls.
10:25 samth: Yann1, your problem is that the name `this' is private to the macro, it can't be accessed from outside
10:26 Yann1: samth: I already thought about this, but how can I solve it?
10:26 samth: http://pastebin.com/Luqw52Ej
10:26 samth: try that - we allow the user to provide the name for `this'
10:26 samth: that way they can choose any name they want
10:27 samth: you can see that the `rec' form in Racket has the same shape: http://docs.racket-lang.org/mzlib/mzlib_etc.html?q=rec#%28form._%28%28lib._mzlib/etc..rkt%29._rec%29%29

11:37 Demosthenes: it appears there are multiple libraries for accessing SQL. i'd lean toward sqlite or postgres for preference, can anyone recommend a racket library?
11:41 (join) anRch
11:41 samth: for postgres, i think people use spgsql
11:43 samth: for sqlite, use jaymccarthy/sqlite (from planet)
11:43 samth: spgsql is schematics/spgsql (also from planet)
11:44 Demosthenes: i saw dbi was trying to replicate a generic front end across db's like perl has.
11:45 Demosthenes: i don't really have much preference, but seems like the other tools build on top of jsqlite so i'll start there

17:05 jonrafkind: although its sort of strange that check syntax mode immediately disables itself after renaming an identifier
17:07 clklein: jonrafkind: hrm, maybe one of our builds is too old/new?
17:07 jonrafkind: mine is silghtly old

18:11 ti84: Hi ! I made a function, that allows me to set a variable... But to do so, I have to run another function first... How can I make it in one function with one of the result not returner?? I'd try to explain with that : (define (function)   (function_I_dont_want_to_return)   (function_which_set_a_variable_from_the_function_I_dont_want_to_return))....  I'm not sure you'll understand but if you have any idea... :)
18:11 ti84: *one of the results not returned*
18:11 jonrafkind: can yhou paste some code
18:11 ti84: ok i do it
18:26 ti84: I'm really not sure I'm clear... but http://paste.lisp.org/display/117304
18:30 jonrafkind: you're passing two variables to grid2 but grid2 only wants one
18:30 jonrafkind: oh wait grid2 vs GRID2
18:31 jonrafkind: ok what is theGrid defined as?
18:32 ti84: yes i know, well its complicated, I've got a looooooooot of functions... TheGrid is just a list of all the lists that makes my grid... and GRID2 displays TheGrid
18:34 lewis1711: you might want to pick some more descriptive names
18:34 lewis1711: like "display-grid"
18:38 ti84: er.. what I want to do, to say it clearly, is not to display the result of an operation in a function... example : (define (function x) (operation1  x) (operation2 x))... How not to display the result of (operation1 x) ?
18:38 jonrafkind: what do you mean (grid) and (GRID2 theGrid) do the same thing, they are clearly different
18:38 jonrafkind: (operation1 x) won't be displayed
18:39 jonrafkind: unles you have some print statement in there
