25d89effd3 implement the rest of the lane table algorithm 
Or, at least, enough to pass the "torturous" `paper_example_g1_build`
test.

7515fccef6 inefficient version of the core lane table algorithm 
The missing piece is updating the lookaheads of the new states that wind
up getting created.

8f3f864688 rename tests to reference the paper more explicitly 
Also include the full G1, which I now see is the smallest example (or
one of them) that requires splitting a state.

70ed503f98 Merge pull request #182 from Marwes/error_recovery_panic 
fix: Don't accidentally cast a reduce action to usize
 2017-02-07 07:08:18 +01:00
Markus Westerlind
b69e679d5b fix: Don't accidentally cast a reduce action to usize 
This caused panics in certain error recovery scenarios as a reduce action represented by a negative number would get casted to `usize` which then caused an index out of bounds panic.

The added tests were extracted and minimized from [gluon's grammar](abd06a4f6e/parser/src/grammar.lalrpop) with the test case below being a minimal reproduction.

Panicking
```
type Test = a ->
```

Valid expression
```
type Test = a -> a
in 1
```

77c82c0cd4 feat: Add the expected successor tokens to UnrecognizedToken errors 
This just adds the terminal strings defined in the grammar which is not the best possible information but it is better than no information.

Partial fix for #58
