* Reverted [pos.mli] to the previous signature, except [Pos.min]
that now takes a labelled parameter [file].
* Reverted [ParserAPI.ml] to the previous signature.
* Reexported [shor_error] in [ParserUnit].
* Changed the modules [LexToken] so that they export one function
to make attributes, the first, additional paramater being "[@"
or "[@@" (and invalid in PascaLIGO).
* Added support in all [ParserLog] for attributes (pretty-printings).
* Added AST nodes [Attr] and [AttrDecl] to PascaLIGO. The simplifier
takes care of hooking them with their respective declarations
or discarding them. (In the future, we should issue a warning for detached
attributes.)
* Duplicate variants in the same type declaration
* Duplicate parameter in the same function declaration
* Shadowing of predefined value in a declaration
I fixed the architecture for that support: ParserMain.ml is now where
those specific errors are handled, and they are produced by the
semantic actions of the parsers.
I also had to remove the keywords [Down], [Fail] and [Step] in
PascaLIGO that made a mysterious and unwanted come back. (I did not
bother with [git blame]).
* [CameLIGO/ReasonLIGO] The AST node [EAnnot] (expressions
annotated by a type) now records the region in the source
code for the colon.
* [CameLIGO/ReasonLIGO/PascaLIGO] I added the syntax
%token <...> TOKEN "lexeme"
* [ReasonLIGO] I changed the AST nodes [Mtz] and [Str] to
[Mutez] and [String], respectively (in accordance with the
PascaLIGO front-end). I changed token [DOTDOTDOT] to
[ELLIPSIS].
* [ReasonLIGO] I added what was missing to make a loca build
with my Makefile.
- I aligned the names of the tokens in common with Ligodity.
- I removed the "down" and "step" clauses in loops.
- Note: the stratification of the rule "pattern" in the
previous commit has the pleasant effect to remove a call
to "corner_case" in function "simpl_case" of the
file "2-simplify/pascaligo.ml".
- Added more cases to the pretty-printer of the AST.
LexToken, AST: Tiny refactoring.
Bug: Added the making of the AST node PBytes.
Parser: The rule "pattern" was not properly stratified (the
constructor "PCons" was always produced, even when no consing was
done (now a fall-through to "core_pattern").
Bug: When sharing the lexers between Ligodity and Pascaligo, a
regression was introduced with the lexing of symbols. Indeed,
symbols specific to Ligodity (like "<>") and
Pascaligo (like "=/=") were scanned, but the
function "LexToken.mk_sym" for each only accepted their own,
yielding to an assertion to be invalidated. Fix: I created an
error "sym_err" now to gracefully handle that situation and
provide a hint to the programmer (to wit, to check the LIGO
syntax in use).
WIP: Started to write pretty-printing functions for the nodes of
the AST.
CLI: The option "--verbose=ast" now calls that function instead
of printing the tokens from the AST. When the pretty-printer is
finished, the option for printing the tokens will likely
be "--verbose=ast-tokens".
