Perl is much better than lisp. I had a fan of lisp tell me that it didn't matter that you could write stronger programs out of the box with certain languages. Evidently the libraries available for each language don't matter and "Lisp could have regexes just as powerful as Perl with the right libraries".

Really? Well where are these libraries that give lisp the same ability to manipulate strings as Perl?

$var =~ /^#include\s*<([^>]+)>/;

$file_name = $1;



(match var (regex (concat beginning-of-line

                          "#include"

                          (zero-or-more-of white-space)

                          "<"

                          (save-contents-as file-name (one-or-more-of (any-char-but #\>)))

                          ">")))

or alternatively,



(match var (^ #include (* \s) < (save file-name (+ ([^ >))) >)

#include <regex.h>

#include <stdio.h>



int main() {

     char *var = NULL, *file_name = "";

     int n = 0;

     regex_t pat;

     regmatch_t matchbuf[1];

     getline(&var, &n, stdin);

     regcomp(&pat, "^#include[[:space:]]*<([^>]+)>", REG_EXTENDED);

     regexec(&pat, var, 1, matchbuf, 0);

     if (matchbuf->rm_so != -1) {

          &var[matchbuf->rm_eo] = '\0';

          file_name = strdup(&var[matchbuf->rm_so]);

     }

     free(var);

}

why do lispers care about perl?

seriously check out the stats of Comp.Lang.Lisp against Comp.Lang.Perl refering to the citation of the other language.

lisper care too much about it

Still waiting for you to show me how lisp can manipulate strings as well as perl...

That's because The Real World™ is not interested in anything more than robotic code monkeys.
