Hello fellow Perl fans,
I'm currently working on a Lua-Perl bridge, and I'm implementing a function perl.require that loads a Perl module from Lua, in the same manner as CORE::require. The usage is as follows:
require 'perl'
perl.require 'Scalar::Util'
This works fine, but if I'm missing a module...
require 'perl'
perl.require 'Doesnt::Exist::Yet'
In this case, Perl dies with a module not found error and calls exit(). Here's my implementation of perl.require:
static int perl_interp_require(lua_State *L)
{
size_t len;
const char *modname;
SV *modnameSv;
modname = luaL_checklstring(L, 1, &len);
modnameSv = newSVpvn(modname, len);
/* Exits on failure */
load_module(PERL_LOADMOD_NOIMPORT, modnameSv, NULL);
check_perl_error(L, 1); // left out for brevity; checks $@
return 0;
}
Is there a way to catch any errors that load_module may throw? I did a quick search for "perl xs load_module catch die", but it yielded nothing useful.
Thanks for any and all help!
