Mac Forum / Programming / Perl / June 2005[OT?] Dynamically loading Perl into C programs
There's a project I'm working on (Paperboy RSS) that's written in C, the simplest part of which is basically applying XSLT to files with libxml2/libxslt. There's a separate but related project written in Perl that's going to use paperboy to do the heavy lifting but needs to be able to let users define their own XSLT/XPath functions. Since these functions are user-defined I need to find some way to dynamically load them into paperboy at runtime. So my question is, what's the best/easiest way to do this? Ideally paperboy would be dynamically loading another C object file so that we could have a number of these for writing xpath functions in different languages; though that's not strictly a requirement. I've had Apache2's libperl suggested to me, but my weak google-fu can seem to find anything relevant on that. Any guidance is appreciated.

There's no way that I know of for embedding chunks of perl (e.g. subroutines) in C without embedding the entire perl interpreter too. To do so would require compiling perl down to machine code, which isn't possible in any clean way. Apache2's libperl seems completely unrelated, except that it also happens to be another example of someone embedding a perl interpreter in a C program (the apache web server). -Ken On Jun 28, 2005, at 3:13 AM, wren argetlahm wrote: > There's a project I'm working on (Paperboy RSS) that's > written in C, the simplest part of which is basically [quoted text clipped - 22 lines] > Tired of spam?
