focalize's Issues

Typechecking issue ? Wrong type generated in Coq.

The same abstracted method from a collection parameter does not have the same type in very similar situations.
In some, it looks wrong, causing the lookup in the collection carriers mapping to fail. Hence, the type is considered as coming from an external top-level collection.

File "./bug.v", line 180, characters 6-45:
Error: The reference conversionFunctions.Super.me_as_carrier was not found
in the current environment.

See the attached file (to rename .fcl). Instructions to reproduce the bug are in comment in the file.
Tester with version 0.9.5, OCaml 5.0.0, Coq 8.17.0.
bug.txt

Unbound reference in Coq code when playing with parametrized collection parameters.

_The reference p_C_foo was not found in the current environment.
For the following code.
I suspect this is related to issue #3 since it also deals with the PRM rule.
The substitution should change _p_C_foo into _p_D_foo.
I'm afraid the way the substitution is applied is wrong since it proceeds collection parameter by collection parameter. Hence if several collection parameters are involved, each time a substitution modifies a type is does not modify the types of the other collection parameters.

open "basics" ;;

species Obj =
  signature elem : Self ;
end ;;

species S (X is Obj, Y is Obj) =
  let foo (x : X, y : Y) = true ;
  property theprop : all x : X, all y : Y, foo (x, y) = true ;
end ;;

species T (A is Obj, B is Obj, C is S (A, B), D is C) =
  let bar = D!foo (A!elem, B!elem) ;
  theorem bar_is_true : bar = true
  proof = definition of bar property D!theprop assumed ;
end ;;

Note the enforced dependencies in the assumed proof.

Installation through opam does not work

I have tried installing FoCaLiZe from the opam file as follows:

opam pin add -k git focalize https://github.com/pessaux-f/focalize.git

I get an error which I guess means that opam sandboxing prevents the use of sudo:

Misusage of Self as an expression

open "basics";;
species Une_Erreur_S =
signature une_fonction : Self -> bool;
logical let erreur (s : Self) =
une_fonction (Self);
end;;

---

Compilation generates:
Error: Unexpected error:
"File "species_record_type_coq_generation.ml", line 992, characters 9-15: Assertion failed".
Please report.

When calling une_fonction, passing Self as argument is incorrect. The broken assertion especially detects this. An error message should be issued instead of an assertion.
Some check should be done somewhere earlier in the compilation pass. May be at scoping if possible. Indeed, Self is syntactically an expression since it is used for collection parameters expressions. Everywhere else, it is illegal.
