I saw a method of doing this awhile ago where
the code was wrapped into c binary. It only prevented
novices from viewing the code, since all you needed to do was
open the binary file and browse through it.
i have a snippet from one of my chat logs ...
/*#define MULTIPLICITY */ /* try not to be a bad boy, avoid tinkering
+with the interpreter's internal structure! */
\#include <EXTERN.h>
\#include <perl.h>
\#include <stdlib.h>
static PerlInterpreter *pi;
static char *script = $scriptText;
int main(int argc, char **argv, char **envv)
{
int l, i, p_argc;
char **p_argv;
char *e_switch = \"-e\";
char *real_name = argv[0];
char *s_argv[2] = { e_switch, script } ;
char **p_envv = envv;
p_argc = argc+2;
p_argv = (char **)malloc(sizeof(char*)*argc);
p_argv[0] = argv[0];
p_argv[1] = s_argv[0];
p_argv[2] = s_argv[1];
for(i=1;i<argc;i++)
{
p_argv[i+2]=argv[i];
}
pi = perl_alloc();
perl_construct(pi);
perl_parse(pi,NULL,p_argc,p_argv,p_envv);
{
SV *sv;
sv = perl_get_sv(\"0\",FALSE);
if (!SvOK(sv))
{
printf(\"%s: unrecoverable error\\n\",argv[0]);
exit(EXIT_FAILURE);
}
sv_setpv(sv,argv[0]);
}
perl_run(pi);
perl_destruct(pi);
perl_free(pi);
return EXIT_SUCCESS;
}
I wish i could remember what it was called or who wrote it. I'll try and find it on my old disks |
