Embedding Pike into C/C++ game

That is indeed very possible. As for callouts, I don't see why they wouldn't work. If we go down the GTK-way of thinking with pike_iteration() and pike_run() methods, one which does one call to the main loop, the other which starts it (i.e run from a thread or so), call_outs would work as long as pike_iteration() is called often enough. / David Hedbor Previous text: >2004-02-23 16:51: >Subject: Embedding Pike into C/C++ game >-------------------------------------------------------------------- >I think the biggest problem is that no one is making a list of the >actual problems that should be solved.

Embedding Pike into C/C++ game
by David Hedbor ＠ Pike developers forum 23 Feb '04

I forgot some things in my original email. This is mostly geared towards the developers of Pike, but I'm copying it to the normal mailing list as well. I wanted to point out that what Kenneth is saying probably is very true. Pike is a very nice and powerful language. Python and Lua are indeed the most commonly used languages in games today. However they aren't without issues - Lua especially (for example very easy to make mistakes that you don't notice until much later). Does Pike have a place here? I think it's possible. It might have a future in games if it was easily embeddable (and behaved nicely in those cases). Of course the other big hurdle is documentation and lack of bugs. That is as we all know a problem that's harder than embedding to solve. So the question is, how does this get solved? Is there a document or notes about issues with embedding? For now, limited to embedding a single interpreter in a process (not worrying about multiplicity as Perl puts it, which is a whole other layer of complexity). Has anyone sat down and looked at this more in detail? / David Hedbor Previous text: >2004-02-23 16:46: >Subject: Embedding Pike into C/C++ game >-------------------------------------------------------------------- >This is definitely not the first time this has been brought up as a >desired feature.

I think the biggest problem is that no one is making a list of the actual problems that should be solved. To me it (since I know so little about the backend, memory management etc) it feels like it shouldn't be that hard to add pike_init and pike_exit that does what main does and then begin to call Pike code (possibly with a set of restrictions like no threads and no call_outs). / Martin Nilsson (saturator) Previous text: >2004-02-23 16:46: >Subject: Embedding Pike into C/C++ game >-------------------------------------------------------------------- >This is definitely not the first time this has been brought up as a >desired feature.

This is definitely not the first time this has been brought up as a desired feature. I'm sure it's also not the last time it will be mentioned. I know that there's been some steps towards this goals but that it's not exactly close to archieving it. I think we all want pike to be embeddable though. As for more detailed status or information on how hard this would be to do, I will leave that to those more involved in the core Pike programming. / David Hedbor Previous text: >2004-02-23 16:39: >Subject: Embedding Pike into C/C++ game >-------------------------------------------------------------------- >Hello! > >I just discovered Pike today, and the more I read the more I am impressed. >I am one of the authors of the game library called ClanLib (www.clanlib.org), >and I'm currently working on a game I need some scripting for.

Pike MUD anyone?
by Mats Lidstrom 20 Feb '04

20 Feb '04

Given Pike's origin I find it somewhat strange that there's not many references to any MUD's in Pike. The only one I know of is Hubbe's YumeMUD and the one I'm currently working on. I recommended Pike on a vworld mailing list and got as a response that they couldn't find anything about it on the Pike web site. I know that the only text mentioning it before was on the testimonials page, but that text isn't there anymore. It's a shame since I'm having problem getting vworld developers to be interested in Pike when it's not "encouraged" on the Pike pages. Anybody got any links to Pike MUD's I could forward? Except YumeMUD then :) /M
