e2299d1078 Require that there either be symbols or action (or both), but not 
neither. This means that an empty production with no action is not
written `;` but rather `();`. This opens door for using more
`match` style syntax.

92d64f854b bootstrapping successfully now (but unit tests prob not working yet; 
lalrpop-test works)

bf2945a6b4 self-hosted parsing is kinda working -- except that 
I didn't implement yet the handling of patterns

d67e04f5e4 setup (but don't yet use) a self-hosting scheme. newparser.rs does 
successfully convert though.

3c67e3c8c5 add LALRPOP grammar written in itself; generates quite a lot of output 
though -- probably need to shift to a less naive LR(1) generation
algorithm

1d4c5d3efc separate out pre/post-validation in order to properly check for 
terminals without defined conversions; also, eliminate the default
conversion

b08e0cfe17 make it possible for tokenizer to generate errors (and thread the 
logic through); use traits to be relatively seamless in what
we accept

91dc00aa89 better test for using super 2015-07-20 13:02:15 -04:00
Niko Matsakis
9f4c82cf36 refactor how we handle locations so that it is only the parse_FOO 
function that does the adaptation for optional location information (is
optional location information even worth it, or should we just default
to `()`)?

8d1fed1e25 change parse_Foo so that it expects to consume entire input; 
later we'll make a version called `resume_Foo` or something that
lets you supply the initial state (lookbehind, lookahead, etc)
in its entirety
 2015-07-20 05:43:07 -04:00
Niko Matsakis
2383a021c9 change the behavior of @< and friends so that instead of supplying 
`None`, they use `Default::default`. You can always give an option
yourself if that's what you want, after all, but most of the time
it's kind of annoying!

ae37f374cc move the action code back into the parent module so that super:: 
resolves correctly (as I originally intended, but forgot) and
add a test
