[antlr-interest] ANTLR 3 Eclipse Plugin

[Shmuel Siegel]

There are three issues that concern me.
1) Separation of source and generated files, definitely a plus when it
comes to re-distribution.
2) Output file(s) need to be in a folder hierarchy that is compatible
with the package statement.
3) Living in existing project structures.

Your suggestion solves items 1 and 2. Item three can wait.

Definitely possible. I'll see what I can do.

I was thinking more along the lines of:

  src/some/pkg/name/Foo.g3
  generated/some/pkg/name/FooLexer.java et al

What do you think? I could make it

  antlr-generated/some/pkg/name/FooLexer.java et al

Toggling the antlr 3 nature would set up the "generated" dir
automatically.

The builder currently marks the generated files as "derived". In Eclipse
3.3 there's an option to warn you if you try to edit a derived file.

As long as the grammar is in some source dir, it will be picked up; you
don't need to specify it. I just need to check the classpath to find
what
prefix to chop off from the grammar's path name when setting up the
output
dir.

Thoughts?
