I'm working on a little project, using 2 languages in 1 program.The first parser is needed to parse the 'configuration', which is stored in a file.
The second parser is then needed to parse and handle the command-line input for user input (it was supposed to be the start of a text adventure engine). So, invocation would be: (assuming the language at hand is called 'pal') parrot pal.pbc foo.pal which handles the configuration file, after which I expect (and get) a command line prompt. However, it seems I cannot get this to work I created a HLLCompiler object for each of the (disjoint) languages, and set the attributes properly (grammar, actions, language) There's 2 grammars involved, and 2 actions files. All of these files are compiled into PIR, and .include-d. The first compilation works fine. Then, I invoke the second parser, which does get activated (there is a commandline prompt), but whatever I put in, it's "Failed to parse source". I tried to invoke 'interactive' method on the second compiler, instead of 'command_line', but this didn't work. I tried to pass "target"=>"parse" to the 'interactive' method, but that didn't work either. I also tried to re-set the parsegrammar and parseactions on the first compiler, after compilation of the configuration file. Pretty much all combinations I tried, but nothing seems to work. Somehow, I get the feeling that there's some state or something being stored, which needs to be reset. That's just a wild guess of course. Anybody any clue? thanks, kjs
