I added and alternate syntax for blocks of instructions. 
The syntax: block { ... }
The other syntax: begin ... end
This implies adding a new keyword to LIGO: "block".

afca07d888 This version of OCaml (4.06.1 with dune/opam) seems to not like shadowing vs. open 
The shadowing worked fine with a standalone ocaml 4.07.1 (no dune or opam use)

3cb9a311ee Disable git commit in Version.ml for now 
It does not work well with opam install, especially if the dune file is not at the root of the repository.

(only as a test expression in conditionals).

I extended the right-hand side of assignments to accept "None" 
without type annotation.

This is meant to enable specify the removal of a map binding.

Note: The index assignments in loops are not concerned.

24c0a33c99 I extended left-hand sides of assignments to have qualified paths. 
Note: In loops over integers, the initial assignment has still a
variable (the index) as left-hand side.

A qualified path is of the form "x" or "x.y.z" or "x.y.z[t]".

I added qualified names (paths) as left-hand sides of assignments. 
For example:

store.funded := True;

Extended map expression to map constants by extension. 
Fixed the grammar for variable declarations (the ":=" had been
disabled by mistake in the last commit).

Ported to constant declaration the work done for variable declarations. 
That is to say, now constants can include unannotated empty lists etc.

Added qualified names to patches ("patch x.y.z with ..."). 
Fixed grammar for map patches (should start with "patch", not "map").

Small refactoring of the AST. 2019-03-20 09:26:24 +01:00

8eaf1a90ec
Maps can be defined by extension in declarations. 
"map" has become a keyword to introduce definition of maps by extension in declarations ("map" ... "end"). This entails that a grammar rule had to be created to handle the type expressions "map (..., ...)". Concordantly, I added map patches, modelled after record patches.

I created a node in the AST for map expressions (currently only
map look-ups).

I refactored the parser with parametric rules.

I relaxed the extension to the grammar that enabled non-annotated 
empty lists and None values as initial values in declarations.

Now, these values are accepted irrespective of the declared type. It
is up to the typechecker to validate them.

623683839f
Removed keyword "null", replaced by two keywords "do" 
and "nothing".

Until now only products of type names were allowed: I extended
them to allow type expressions.

Removed the destructive update of a map binding "a[b] := c".

Record projection has been extended to allow for qualified
names: "a.b.c" and "a.b.c[d]".

Changed the LIGO extension from ".li" to ".ligo".

Fixed the name of the language to be "LIGO" (instead of "Ligo").
