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.
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).
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".
This changes the `decl_ctx` to be toplevel only, with flattened references to
uids for most elements. The module hierarchy, which is still useful in a few
places, is kept separately.
Module names are also changed to UIDs early on, and support for module aliases
has been added (needs testing).
This resolves some issues with lookup, and should be much more robust, as well
as more convenient for most lookups.
The `decl_ctx` was also extended for string ident lookups, which avoids having
to keep the desugared resolution structure available throughout the compilation
chain.
it is useful e.g. to be able to print intermediate ASTs when they don't type, to
debug the typing errors. This is better than commenting the typing line each
time.
Note that the option is not available on all targets (esp. not for ocaml and
python outputs ; it's allowed on the interpreters for debugging purposes but I'm
not sure if that's a good idea)
this is more consistent, avoids empty stamp files and should make things simpler
overall.
The slightly tricky `-C` option is added to Catala so that it can be run from
_build while paths to source and destination files are still specified relative
to CWD (Ninja doesn't provide string manipulation, so otherwise we would have to
explicit both the `_build/dir/` and `dir/` versions of each path).
* Obsolete code for included tests has been removed
* The engine uses a proper lexer and is much simplified
* An inline test in the middle of the file now only "sees" the file up to that
point. This fixes an issue where we had spurious errors when a type error was
added at the end of a file, and it would pop up in tests before it. This makes
files including many tests much more practical.
* diffing and resetting the tests has been reintroduced (done at the moment in
Ninja, but for more control (count number of failed tests, etc.) we could put it
back into Clerk at some point
* The Catala CLI can now take an input from stdin (with the possibility to link
a (possibly fake) on-disk file for error reporting and file locations ; this
is useful for running tests)
We need a concrete intermediate target for e.g. transitive uses of `> Include`
for Ninja to correctly handle them.
Of course we could also unroll all transitive dependencies, but meh.
Note also that now tests now just generate the outputs but facilities for
diffing and resetting are temporarily absent.
Rather than require all files to be listed on the command-line (and having to
check consistency with `> Using` directives), the main catala CLI is now a bit
more clever.
⇒ There is a new assumption that a module name definition must match the file
name (up to case and extension) — with appropriate error handling to enforce it.
In exchange, `> Using` directives are now used to more transparently lookup the
appropriate `.catala_*` interfaces and the compiled artifacts for the used modules (handling transitive dependencies), with just standard `-I` flags for when they need to be looked up in different places.
