[racket-users] Re: Hidden a list
I followed the recommendation with hash tables and used a struct to wrapping the data. I will check this code and will look the efficiency. Thanks for the time.

[racket-users] Re: Hidden a list
I understand that struct is not collections of key-value, in the code appear in this way for reference, even label. The problem that I have is in the macro set-s in the formation of the accesors to fields of structure. This generates (set-usuario-key! ..) instead of (set-usuario-nom! ..) into with-syntax. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

[racket-users] Re: Hidden a list
Thanks, This start because I need a syntax like the next: (define u (make-s user (nom ape sexo)) (set-s u ((nom "nom" ) (ape "ape"))) (get-s u 'nom) u ; --> '((nom "nom") (ape "ape") (sexo "")) And I start using lists but I can't hidden. From there I changed to a struct but now I get this problem. set-usuario-key!: unbound identifier in module in: set-usuario-key!

[racket-users] Hidden a list
Hello guys,
There any way to hide the contents of a list as does the structure?
(define lst (list "abc" 123 (+ 12 32)))
lst ; --> '("abc" 123 44) something like #
(define-struct user (nom ape))
(define u (make-user "nom" "ape"))
user ; --> #
u ; --> #

[racket-users] regexp-match? problem
Hey, I have this problem, I want filter values from DPTO1 to
DPTO99 (DPTO is a word with letter O not zero) but I don't
get that. with #rx mark error/false with DPTO2, DPTO3, etc but with
DPTO111, DPTO100 is good. with #px all is true for both DPTO222
or DPTO12. How filter this range correctly. Thanks.
(define dpto "DPTO2") ; legal values are from DPTO1 to DPTO99
(if (regexp-match? #rx"DPTO[1-9]{1,2}" dpto)
(display "true dpto")
(display "false dpto"))

[racket-users] Test request
Hey guys I'm proving this app and I will be grateful if can help me with new ideas or evaluate it. I create a serie of videos that show your functions and objetive. Exist a survey that you can respond, it is in http://goo.gl/forms/jsNIgRvdr8 together with the videos. Not is problem if you respond in other language. The app is in 52.35.22.103:8000 and the results you can see in 52.35.22.103:8900. Thanks in advance.

[racket-users] Independent data structures
Hey guys, I have a big problem, when I started this project I completely ignored split the data for each user, and the results of that is the manage of one user for time, really bad. Now I try resolve this and all ideas result very dificult (at least in code). I can resolve a part of this problem, the storage in disk, creating one file for each user with your data, but this don't fix the problem of keep those data independent from the other users in memory. (a second user can modify the data of the first user and viceversa under the same data structure). I think in threads, each with its own data structure, but I don't know if this is possible and how make that. The project is https://github.com/hmcab/anauj and the data structures to change are (vcamposg , vcamposg-td , vcrudg , vcrudg-per). Any other idea? I need only new ideas and examples.

[racket-users] Re: racket execution
Hi Asumu, Thanks for reply, the project is in https://github.com/hmcab/anauj.git , and the server run from generacion-datos/codegen.rkt on the bottom the file. Read the readme file before the execution. At this time I have the application on amazon server to prove it, but every time that I leave the ssh connection, and so, the application is executed with racket -t codegen.rkt &, this falls (no any access from the browser is achieved), but if I enter to the amazon server with ssh again, the process is still there. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

[racket-users] racket execution
Hey guys! I'm trying execute a web application in background or (like daemon ej. apache/httpd) in this way racket -t webapp.rkt or racket -t webapp.rkt & , but none of them work. I also tried with raco exe codegen.rkt and then ./codegen & but without good results. Is something with the configuration of server?

[racket-users] little problem with comma (unquote)
Hi for all
I'm trying generate a function from other function, in this case is a little
part of it (expression) that need print a comma within it. In the example show
below need print the comma before (embed/url ,f). that is say ,(embed/url
insertar-empleado) but is something I can't to make.
I have this.
#lang racket
(define f 'insertar-empleado)
(define exp `(embed/url ,f))
(define (make-func)
(define str
`(define (func)
,exp))
str)
(display (make-func))
and result this (define (func) (embed/url insertar-empleado)) and I need
(define (func) ,(embed/url insertar-empleado)).
I treated with (' quote) (`quasiquote) and (, unquote) but no reach the
result.
This is all, thanks in advance for read and help me.
