Evan Czaplicki
c140d690fc First draft of cross-module type checking 
Currently, all top-level types are imported. No alias resolution
happens so you need to use "import open M" atm.

Evan Czaplicki
807076ad57 Add CSaveEnv, optimize CAnd, make it prettier 
CSaveEnv is a special constraint that indicates that the current
environment should be saved for later use.

8145e600fc Create MetadataModule for more refined information about modules 
Used in most places to break a module into more orthogonal components.
Some of this data needs to be serialized into the interface files.

Evan Czaplicki
67ef1ec77b Create the Type.Inference module which handles type inference from 
start to finish. Give it a Module and it returns a dictionary mapping
top-level values to types.

18adffc06d Turn unary negation back on. 2013-07-16 00:36:34 +02:00
Evan Czaplicki
90d50dbb13 Turn off unary negation parsing for now. It has weird behavior when 
paired with function calls:

  (- sqrt 9)   -- parse error
  (-sqrt 9)    -- type error, cannot negate function
  -(sqrt 9)    -- this works
  - (sqrt 9)   -- parse error
  - sqrt 9     -- parse error
 2013-07-15 12:22:04 +02:00

Evan Czaplicki
0070a844d0 Switch the internal data constructor name for tuples. Before tuple 
constructors could be shadowed by user defined ADT's such as "Tuple0",
"Tuple2", etc. Now it uses "_Tuple0" to make it impossible to overlap
with user defined ASTs.
 2013-07-14 19:52:50 +02:00
Evan Czaplicki
343dcf2250 Add support for unary negation with the '-' symbol. Makes the use of 
'-' whitespace sensitive, as in the unary negation proposal in
elm-discuss.

f -1  == f (0-1)
x - 1 == (x-1)
x-1   == (x-1)

Evan Czaplicki
7f433922ed Create module to sort let-blocks into "strongly connected components". 
This does two things:

  * makes it possible to automatically generalize functions without
    bothering the programmer about managing dependencies.

  * sorts values such that they'll be defined in the appropriate order
    when they are mapped down to JavaScript.
 2013-07-12 22:24:12 +02:00
Evan Czaplicki
4d7562f317 Begin generating constraints for whole programs. Need to perform 
dependency sort within let-expressions for things to work properly though.
 2013-07-12 16:21:07 +02:00
Evan Czaplicki
4208b5c9de Remove some debugging stuff and generally clean up the code. 
There was one potential error in which a debug needed to be a liftIO,
the computation it performed was not optional.
 2013-07-12 11:05:03 +02:00
Evan Czaplicki
b0387821b4 Fix error in generalization in which some variables would escape their 
rank. Problem was that young variables were not all being marked as
young.

This resolved a soundness issue described in the post on
"How OCaml type checker works".

cb914d91ff Get all of the Haskell files compiling with the new type checker.

stopgap measure.

f87e316847 Make pretty printing properly parenthesize higher order functions. 
Not the best implementation, but it is simple and works well.
 2013-07-09 21:59:58 +02:00
Evan Czaplicki
497d478d26 Get the solver working on basic programs. It outputs pretty types for the 
variables in the program. Need to test further and start doing some benchmarking.
 2013-07-09 21:52:05 +02:00
Evan Czaplicki
ca62ee64a9 Create type pools, have an organized model of state to flow through 
the State Transformer during constraint solving and variable unification.
 2013-07-09 10:25:50 +02:00
Evan Czaplicki
4c51159f2a Create a Type.Pool module specifically for variable pools. Start using 
a state transformer to thread the pool and errors through.

Evan Czaplicki
0ed72056b6 Add pretty printing for type constraints. 
Convert source-syntax types into type-checker types and print them
with pretty type variables.

Generate constraints for let-expressions using type annotations.

Build test function to turn strings into type constraints.

947b82ed09 Switch more files over to new Expressions 2013-07-04 17:31:22 +02:00
Evan Czaplicki
5c68f6bb73 Convert more files to the new Expression format that relies more on 
patterns. Seems to clean things up so far.

Also, begin adding a module that resorts definitions to make sure
that each definition comes after the ones it depends on. This will
also make it possible to disallow recursive values statically.
 2013-07-04 17:24:04 +02:00
Evan Czaplicki
69ed7631fe Start switching over to an AST that uses patterns in lambdas and 
pulls the arguments out of Definitions (placing them in lambdas).
 2013-07-04 11:36:08 +02:00
Evan Czaplicki
351c33c486 Start generating constraints for let-expressions. Account for mutual recursion,

Andrew Miller
1b4aca9685 Turn off debug code that printed all constraints during unify. 
This debug code is very noisy and makes it hard to test the dev
branch because you can't see warnings buried in all the debug
output.
