0530810f10 modify generate code to require a utility library (lalrpop-util) and 
to generate errors based on the error type defined therein

91dc00aa89 better test for using super 2015-07-20 13:02:15 -04:00

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

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

4c74cc6873 Move the LALRPOP tokenizer into lalrpop itself; rename the existing 
token to lexer; add a few more tests and fix a bug in `test`

6da930bbf6 get lookahead/lookbehind working, and add a test to laprpop-test for it 2015-07-18 18:14:39 -04:00

f758e0ff00 thread through most of the work to support lookahead/lookbehind, 
but not the actual expansion (untested, clearly)

fad838a361 modify recursive ascent to expect (loc, enum, loc) when a location type 
is specified, and modify test tokenizer to provide it

ccf9320b10 introduce a write_fn_header fn and use it in a few places, 
with the intention of making it possible to thread grammar parameters
through

4cf8bd92f2 update tests to just write grammar; instead of grammar { }, 
avoiding pointless rightward drift

4921ddbfc2 Port the LR(1) state construction code to use KernelSet, 
which reveals that the assoc type direction is wrong,
it should be parameterized by the richer type of the Kernel
than by the index

5c782c182e Fix lots of things, but the new pattern mechanism works -- we can match 
and extract subbindings, and terminals no longer have uniform type. Very
nice.

ae821645e9 change format of token declarations to extern token with an enum 
section, paving the way for more advanced concepts; also, refactor Types
interface to make it possible to have different types depending on the
kind of terminal

makefile
