Templates missing ?

[ohboyohboyohboy]

hmmm -- every template should be in there. Here's my hunch -- do you have another version of ANTLR installed on your system and accessible from your CLASSPATH environmental variable? Missing templates probably means ANTLR's loading the half-implemented Ruby templates that it ships with.

On my system, antlr4ruby -fo CPP CPP.g works without any errors. However, in the past, I've occasionally had those `missing template' errors pop up, and usually it's due to some interference from the old ruby target creeping in somehow.

I checked to see if maybe there was some unnoticed issue with updates to the customized ANTLR jar (java/antlr-full-3.2.1.jar) by doing another full clone of the repository and then comparing the jar contents -- everything's identical. My template files also include those template definitions it's reporting as missing , so it appears as it should be. So my hunch is it's interference with another installation of antlr on your classpath, in which case perhaps the antlr4ruby script should make sure to unset that environmental variable before executing the java command...

If it is, try temporarily purging your install out of CLASSPATH and retrying
antlr4ruby CPP.g

Thanks for filing these reports -- they're really useful at this stage.

Your hunch was correct . i had installed antlr3 in (OSX) ~/Library/Java/Extensions before in my frustrated attempts to get it running ...

after i switched to a 1.8.7 ruby runtime most/all of my earlier issues seems to have dissapered ...

thanks

no problem -- I didn't think having another version just in your class path would interfere since it's all in the same jar, but guess it does ... I should probably modify antlr4rub to work around that since everything ANTLR needs is in that jar. Thanks -- feel free to report any other issues/ questions along the way. Good to hear that most of the drama seems to be wrapped up.

just to clarify . it was the proper(?) antlr3 -jar and st.jar + antlr3_runtime.jar included ...

do these differ from the antlr4ruby antlr3 .jar in any way ? ...

The antlr jar at java/antlr-full-3.2.1.jar is essentially the "full" project jar, which contains ST v3, ANTLR2, ANTLR3, GUnit, and the runtime java files -- everything ANTLR needs to run. The only difference is that there's a replacement for the RubyTarget class in the tool's source and there are 6 StringTemplate group files replacing the original Ruby template file it contained.
