Parrot as an extension language
Hello, I am writing an XSLT 2.0 processor, and I want to give users the option to write their own message and error handling routines and the like in their favourite scripting language. So I thought of using parrot. But when I look at http://www.parrotcode.org/docs/embed.html, I can see no way of getting information back from the script - not even an exit code. Is there anyway of doing this that I have missed? -- Colin Adams Preston Lancashire
Re: Parrot as an extension language
you'll probably want to use the Parrot_call_sub_* API to call individual subroutines and get return values. perldoc extend.c in the parrot source for more info. you might also have a look at the mod_parrot source (http://www.smashing.org/mod_parrot), which is one of the few apps embedding parrot at the moment. the other is pugs (http://www.pugscode.org), but it's written in haskell. -jeff On 17 May 2005, Colin Paul Adams wrote: Hello, I am writing an XSLT 2.0 processor, and I want to give users the option to write their own message and error handling routines and the like in their favourite scripting language.

Something like this: my $interp = Parrot_new(undef); # ... load a .pir file or some other code into $interp ... my $code_pmc = Parrot_find_global( $interp, const_string(Namespace), const_string(sub_name), ); my $return_str = Parrot_call_sub( $interp, $code_pmc, const_string(SS), const_string(Your_input_string_here), ); Thanks, /Autrijus/ pgpMe8pdQExhO.pgp Description: PGP signature

t/src/manifest.t failed
I'm seeing the following test failure at r8113 t/src/manifestNOK 6# Failed test (t/src/manifest.t at line 79) # Extra files: # dynclasses/build.pl # editor/imc.vim # install_config.fpmc # t/src/.manifest.t.swp # test.imc # test.pbc # Looks like you failed 1 tests of 6. t/src/manifestdubious I started tracing through how it got here. I gather that MANIFEST.SKIP is constructed by gen_manifest_skip.pl which is fed by Parrot::Distribution which gets its info from svn:ignore I see that stuff like the .swp file above should probably be an ignore for the entire project for something like ^\..*\.sw.$ (Vim swap file) But the other things, I'm new and not sure yet what they are. I think the inc.vim may have been created by the Makefile in editor/ when I had it create syntax highlighting. -Dino -- .~.Dino Morelli /V\email: [EMAIL PROTECTED] /( )\ weblog: http://categorically.net/d/blog/ ^^-^^ preferred distro: Debian GNU/Linux http://www.debian.org

The last two pmc's are allocated from a place which is clearly not the pmc pool arena from which other pmc's are allocated. Run is_pmc_ptr(interp, pmc) or check the involved pmc arenas to verify this assumption. leo
