Lots of tests have a new warning because they were calling subscopes without
using their outputs. A better solution could be to mark these subscopes as
`output`, now that it's possible !
They are to become citizens of the same class if we want to allow
output-subscopes (without unnecessary complications like deconstructing and
reconstructing the same structure). And it's reasonable to assume that they
share the same namespace.
With this we should shortly collapse the (internal) ambiguity between
- `subscope.subvar`: access to a variable within a subscope
- `subscope.subfield`: access to a field of the output structure contained in a
subscope variable
With the subscope a variable, these should now become strictly equivalent, so
the plan is that the first could be removed.
- This adds a `catala depends` command that recursively tracks module dependency.
It can then be used by Clerk for linking.
- Generation of cmo object files are added for OCaml (we only built native
objects, but jsoo requires bytecode).
- Some fixes to the generation of value embed/deembed shims (related to types
coming from different modules ; add support for options ; etc.)
Print to json directly rather than depend on yojson and a ppx.
Note: this should be tested with the website in order to validate that the Json
output is 1-to-1.
(a second step could be to simplify this output, now that it's manual)
Through the syntax `var_name state state_name`.
Addresses #567, but
- requires documentation
- explicitely accessing states of the variable being defined is not allowed at
the moment (warning proposed in #567 requires a whole-expression check, which
is better done some place else entirely)
This allows for retyping after monomorphisation: a new function just extracts
the return type of the operator, without checking the operand types.
Also to avoid multiplying function arguments around the typer, the flags have
been gathered in a record that is included in the typing environment; it's ok to
give them default values as long as these are the strictest.
so don't retype after monomorphisation, which is now possible as the pass itself
correctly preserves types.
In time the typer will need a special case to get knowledge of the new types and
modified operator types.
A little bit of effort enables us to propagate valid typing annotations, making
subsequent typing re-inference easier (and avoiding a traversal just to remove
type annotations)
since it doesn't correctly propagate and update types. (Ideally it would, but
otherwise it would be better to remove the type annotations on the fly instead
of introducing wrong ones then cleaning them up).
The primary use-case for this was to be able to run computations on a list of
structures, then return an updated list with some fields in the structures
modified : that is what we need for distribution of tax amounts among household
members, for example.
This patch has a few components:
- Addition of a test as an example for tax distributions
- Added a transformation, performed during desugaring, that -- where lists are
syntactically expected, i.e. after the `among` keyword -- turns a (syntactic)
tuple of lists into a list of tuples ("zipping" the lists)
- Arg-extremum transformation was also fixed to use an intermediate list instead
of computing the predicate twice
- For convenience, allow to bind multiple variables in most* list
operations (previously only `let in` and functions allowed it)
- Fixed the printer for tuples to differentiate them from lists
*Note: tuples are not yet allowed on the left-hand side of filters and
arg-extremums for annoying syntax conflict reasons.
Always generate the version through git when possible, and encode that within
the binaries so that `catala --version` does'nt give misleading information.
Previously we used dune's builtin functionality, but that resorts to a hack at
install time which is unpleasant and doesn't work with our use of `opam
install`.
The cost is a re-linking of catala_utils and the binaries upon git commit, which
is hardly noticeable.
With the new EAppOp node, the typing of operator application has changed and this causes some problems
with the example in test_scope/good/nothing.catala_en when retyping the LCalc to go to Scalc. This
commit changes the weird thing that for generating Scalc, the "typed" parameter was set to "untyped".
