external module building and environment
by Bill Welliver 29 Jul '04

29 Jul '04

I was wondering if anyone knew if there was any rationale behind the behavior of pike -x module with respect to environment variables. The current behavior is for any environment variables that were in effect for the original build process to take precedent over any in the current environment. This means that it's not possible to use CPPFLAGS and the like to help configure find new libraries and headers. Obviously, that's rather inconvenient. Shouldn't it be the other way around? Maybe the behavior should be more sophisticated (ie combine them)? Any thoughts? Bill

Hmm, did I missread you or did you get me wrong? Anyway, private will not allow anyone to inherit and extend, it will allow someone to reimplement. Ie, if you have class Foo { private void a(); } class Bar { inherit Foo; void a(); } then Foo.a is not visible from Bar at all. Only Bar.a is accessible. / Marcus Agehall (nu med semester) Previous text: >2004-07-23 07:37: >Subject: Re: Access control >-------------------------------------------------------------------- >Marcus Agehall (nu med semester) @ Pike (-) developers forum wrote: > >>Come to think of it, private might be right anyway.

Come to think of it, private might be right anyway. Of course one may subclass and override, but that is only because the private methods and classes does not exists (well, they aren't visible anyway) in the subclass. If the intention is to create a class that should only be accessible from your code and never used by subclasses, I would go for private. Anyway, the modifiers in pike are somewhat confusing if you try to apply knowledge from some other language to them... / Marcus Agehall (nu med semester) Previous text: >2004-07-22 07:57: >Subject: Re: Access control >-------------------------------------------------------------------- >Marcus Agehall (nu med semester) @ Pike (-) developers forum wrote: > >>Ah, that is true. >> >> / Marcus Agehall (nu med semester) >> >>Previous text: >> >> >>>2004-07-20 16:22: >>>Subject: Access control >>>-------------------------------------------------------------------- >>>private is almost never right, since you can inherit and modify then. >>> >>>/ Martin Nilsson (DivX Networks) >>> >>> >>> > >Thanks, I'll look what I get with different attributes. > >//Andreas > > > / Brevbäraren >

Access control
by Kaos ＠ Pike developers forum 21 Jul '04

Hi, I wonder if there's a way to hide a class so only another object/class from the same module can instatiate new objects of the program. I tried to declare the class as `static', which hides it, well enough. But given a instance of this class makes it possible to get around the lock by doing: program p = object_program( my_obj ); object new_obj = p( args ... ); Any way to prevent this? Not a big deal, really, just a thought. //Andreas

Ah, ok. Yes, your guess is correct. I'll move it to modules/Lua and see if I can manage to get the installation to put it in Public/Lang/Lua. Is it only monger who does that, or does it work like that when building with make as well? //Andreas / Kaos Previous text: >2004-07-20 14:33: >Subject: Re: Module name >-------------------------------------------------------------------- >Can you maybe elaborate a little more?

Hi, How should I go about to make configure pick up my module when not placed directly in the modules dir? (i.e. in a subdir like Public/Lang/..)

Re: cmod and pike objects

Thanks, I'll have a look at it. Got some nice examples from the SDL module amongst others as well.. Btw, I'm halfway through to a usable Lua[1] binding module. Thought I could post it on modules.gotpike.org. Question: where in the namespace would be a suitable place to put it? I've thought about Public.Lang.Lua or simply Public.Lua. Any guidelines regarding this? And, before I do, I guess I should get it to run with 7.7 and monger as well :o) //Andreas [1] http://www.lua.org / Kaos Previous text: >2004-07-14 14:08: >Subject: Re: cmod and pike objects >-------------------------------------------------------------------- >There are some very basic docs on the pike website, but imho they don't >even scratch the surface. > >If you're interested in calling pike functions from a cmod, you might >want to take a look at the System.PAM module, the conversation function >gets called by the cmod using safe_apply, iirc. > >Bill > >On Jul 13, 2004, at 8:45 AM, Kaos @ Pike developers forum wrote: > >> Hi, >> >> Is the documentation (more than the very basics) for cmod's "RTFS" >> only? >> >> I'm trying to figure out how to create Pike objects from my cmod, and >> invoke their functions. >> Is calling functions on existing objects used with safe_apply()? with >> args and result on the stack I guess. >> >> more questions to come, I'm sure.. ;o) >> >> Oh, btw, I'm using Pike 7.4 from CVS. >> >> Thanks > > > > / Brevbäraren >

Glue for C++ libs
by Marcus Agehall (nu med semester) ＠ Pike (-) developers forum 15 Jul '04

If I were to write a glue for a C++ lib, what special considerations must be taken into account? Are there any such modules in Pike right now?
