Hi all, I've been searching for an answer to this questions for a while
now. Perlmonks.org suggested this list, I wonder if anyone might have
some insight that the could share:
I have a C application that needs to execute fragments of Perl script
provided by the user.
I have successfully embedded the Perl interpreter, and it is working
great. The next step is to provide the ability for the user to make
calls into my C program to get certain information, take certain
actions, etc. I have written an extension using SWIG, and built that
into my program as well. After constructing my perl interpreter, with
the appropriate xs_init function that adds my DynTrans as a static XSUB,
I immediately use:
eval_pv("use DynTrans;", FALSE);
To get my custom functions into the perl interpreter's namespace. This
all works correctly, and I can call into my C program from the Perl
script.
So, the problem: In order for this to work, I have to have DynTrans.pm
in the directory where I run my application. I want to remove this
requirement, I want the entire application to be completely
self-contained. I have gone so far as to modify my code like this:
perl_setup_module();
eval_pv("use DynTrans;", FALSE);
perl_cleanup_module();
The perl_setup_module creates the DynTrans.pm file, and the
perl_cleanup_module deletes it, and this also works. However I don't
like the fact of needing to drop a temporary file on the user's
filesystem.
So, the question: Is there a way that I can make XSUBs availiable to my
perl interpreter without having to have the .pm file around at all? I
tried building the entire .pm file into my application with a series of
eval_pv() for every line, but of course that didn't work.
What I would really like is a programatic interface into whatever the
use DynTrans; perl stuff does. I have read and re-read perlembed,
perlxs, perlguts, perlapi, perlcall, several perl books, forums,
SuperSearch, etc. and I cannot find a way to do this.
Can anyone save me from the dreaded .pm file? Thanks in advance.
