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".

I added support for set membership.
Syntax: if s contains e then ... else
(only as a test expression in conditionals).

I added set definitions by extension.
For example:

const bar : set (int) = set 1; 1+1; f(3); end

Changed "||" -> "or" and "&&" -> "and" to be more Pascal-like. 2019-03-20 12:28:25 +01:00

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.

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").

Added keyword "storage" as parameter kind (with "var" and "const") for
entrypoints.

Removed storage and operations declarations: entry-points now take the
former and return the latter.

I added record creation (injection), field selection (projection)
and functional update (copy).

The only creative piece of concrete syntax is that of the
expression for functional updates:

copy foo with record field = value end

where "copy", "with", "record" and "end" are keywords.

Storage and operations are now explicitly named.
Refactoring of AST to enable the detection of incomplete pattern
matchings by the OCaml compiler. Some record fields renamed for
better readability.

I fixed the pretty-printing of strings.
