[antlr-interest] Trying antlr for python/javascript targets, bad timing?

[Axel Hecht]

My use-case is somewhat involved in that we're changing l10n paradigms,
moving towards a declarative programming language. The overall structure is
simple, but it does end up with a templating language with expressions and
filters. We want to be able to do some level of static analysis on those
"programs" to make sure that references from one localized string to another
work, and the type definitions within that programming language depend on
the human language. I.e., a noun in English is different to a noun in
Polish.

And of course, the details of the underlying grammar are not laid in stone
at this point.

The goal is to take source code in what we call 'lol files' and turn them
into js code that is then read and runtime and used as state machine to
generate the final localized strings.

Further reading is at https://wiki.mozilla.org/L20n. The grammar is a tad
simpler at places, and a tad more complex at others than the one at
http://people.mozilla.com/~axel/l20n/grammar.html.

So, we're not really simple in both the input, the output, and the
processing requirements, and I'd love to be able to not reinvent wheels.
That said, I've forgotten most of what I ever knew about java, and never did
any real work. I'm a python toolchain guy for the most part these days, with
some js.
