The supplied jar works. But if I make a new one with make, and then try to interpret some example, I get:

parsing: examples/fibonacci.fimpp
Exception in thread "main" java.lang.NoSuchMethodError: scala.util.parsing.combinator.Parsers$class.lastNoSuccess_$eq(Lscala/util/parsing/combinator/Parsers;Lscala/util/parsing/combinator/Parsers$NoSuccess;)V

    at stasiak.karol.fimpp.Main$.main(Main.scala:22)
    at stasiak.karol.fimpp.Main.main(Main.scala)

For reference, this is the output of make:

src/stasiak/karol/fimpp/FimppParser.scala:334: warning: match may not be exhaustive.
It would fail on the following input: Error(_, _)
    parseAll(module,s) match {
            ^

cd target && jar cfe ../bin/fimpp.jar stasiak.karol.fimpp.Main stasiak

Error: Could not find or load main class stasiak.karol.fimpp.main

Not sure if it is my fault, or a code error, or what. I have the newest JDK, recompiled from scala, ran straight out of the box, compiled into new jars twice, and everything. Not sure exactly whats going on. Is something mislabeled in the code or am I completely missing something?

Conjuctions don't work well because the parser confuses the word and with the syntax for tuples.

For instance, this works with or:

Applejack has more than one or Pinkie Pie has more than one

[1.60] parsed: Alternative(
  List(
    Relational(
      VariableValue(applejack),>,NumberValue(1)
    ), 
    Relational(
      VariableValue(pinkie pie),>,NumberValue(1)
    )
  )
)

However, replacing or with and:

Applejack has more than one and Pinkie Pie has more than one

[1.47] failure: ‘Has’ ain't no pony I've heard of. Do they have tea parties with ‘Has’?

The source of the problem is that the parser attempts to make a tuple from one and Pinkie Pie has ..., which in turn attempts to make an identifier from Pinkie Pie has .... This then fails here because has is a keyword.

I think ^? combinator is not the right approach here. The check for keywords should make the parser backtrack instead of failing.

If one updates both Scala and Java to compile, the later version of scala will require both building and running linked to the scala-parser-combinators jar file. I am not sure what the solution should be. My suggestions would be either a version requirement or version checking in the makefile.

I'm trying to write the Fibonacci sequence in FiM++, but I get strange errors, to the point where I can't even use the syntax in the syntax folder anymore!
Example:
Rarity's Gems now becomes add Rarity's Gems and Spike's Hoard.

It claims that 'and' is not recognized, and the phrase:
Rarity's Gems now becomes Rarity's Gems plus Spike's Hoard.

Throws from the RegEx saying it was looking for 'got' but found '." (period) instead...

Am I just doing this all wrong, or is this more WiP than I though?
