Re: flisseq() and filtre()

Hi,

Here I give an example which may illustrates my previous post.

--------------------
iwao@kagemaru:/usr/home/iwao/Lang/C/Pari {504}$ cat ./study_flisseq.c
#include <stdio.h>
#include <stdlib.h>
#include <pari.h>

/* 
 * flisseq seems not to handle `\' properly.
 */

int
main (void)
{
  char inputs[] = "v=[[1,1;0,1],\\\n[0,1;-1,0]]\n";
  GEN v;

  pari_init (2000000, 2);
  printf ("inputs = %s\n", inputs);
  printf ("filtre(inputs) = %s\n", filtre ((char *) inputs, NULL, 2));
  v = flisseq ((char *)inputs);
  printf ("evaluated = %s\n", GENtostr (v));

  return EXIT_SUCCESS;
}
iwao@kagemaru:/usr/home/iwao/Lang/C/Pari {505}$ gcc -o study_flisseq study_flisseq.c -I/usr/local/include/pari -L/usr/local/lib -lpari-2.2 -lm
iwao@kagemaru:/usr/home/iwao/Lang/C/Pari {506}$ ./study_flisseq
inputs = v=[[1,1;0,1],\
[0,1;-1,0]]

filtre(inputs) = v=[[1,1;0,1],\[0,1;-1,0]]
  ***   unexpected character: v=[[1,1;0,1],\[0,1;-1,0]]
                                           ^------------
  ***   Error in the PARI system. End of program.
--------------------

I expected inputs strings filtered and evaluated as
`v=[[1,1;0,1],[0,1;-1,0]]'.
Thanks.
