package minicaml

0.3.1 2019-12-26

Added

• map2 primitive
• Reading programs from files
• An abstraction that allows treating primitives as functions, and so allows currying and all the fancy stuff.
• Examples in the examples/ directory
• Greater or equal to and Less than or equal to operators
• More test coverage.

Bugfixes

• Fixed various bugs of 0.3

0.3 2019-12-25

Added

• A simple AST optimizer
• Multiple let assignments (let x = 2 and y = 3 and z = ... in ...)
• Function currying (partial application)
• Strings
• Sequences of expressions separated with ; are treated as a single expression that returns the value of the last one.
• Function pipelining (reverse composition) with the >=> operator. ((fun x y -> x + y >=> g) 1 2 is g 3)
• Dictionaries ({"hello": 123, "world": 345})
• Map, foldl and filter on lists and dictionaries
• Testing and code coverage using alcotest and bisect_ppx

Bugfixes

• Fixed function application parser

0.2.2 2019-12-13

Added

• let lazy rec (or let rec lazy) to define recursive lazy functions
• Command line option parser and man page
• Command line option -v (--verbose) to tell the REPL to show the AST and reduction steps.
• Evaluation step printing is now done in correct order and nesting.

Bugfixes

• Fixed boolean primitives.

Removed

• lazyfun and lazylambda statements.

0.2.1 2019-12-12

Added

• Optional lazy evaluation! You can use let lazy to define values that will be evaluated only when encountered in the let lazy expression body.
• Lazy anonymous functions! Just like the let lazy statement you can now use lazyfun or lazylambda to define anonymous functions which arguments will be lazily evaluated.

Bugfixes

• Fixed precedence levels in parser

Roadmap

• Cache for lazy evaluation
• Partial application

0.2 2019-12-08

• Unit

0.1 2019-12-03

Added

• Initial release of the project
