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.
- Add a `-I` option that allows defined modules to be available from other
directories
- Add reporting of the number of successful / failed tests
- Locate the project root, and always run the commands from there
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.
This makes sure `catala module` finds the local runtime when run from the catala
source tree; and fixes lookup of the catala exec on custom uses of `clerk runtest`.
- Use separate functions for successive passes in module `Driver.Passes`
- Use other functions for end results printing in module `Driver.Commands`
As a consequence, it is much more flexible to use by plugins or libs and we no
longer need the complex polymorphic variant parameter.
This patch leverages previous changes to use Cmdliner subcommands and
effectively specialises the flags of each Catala subcommand.
Other changes include:
- an attempt to normalise the generic options and reduce the number of global
references. Some are ok, like `debug` ; some would better be further cleaned up,
e.g. the ones used by Proof backend were moved to a `Proof.globals` module and
need discussion. The printer no longer relies on the global languages and prints
money amounts in an agnostic way.
- the plugin directory is automatically guessed and loaded even in dev setups.
Plugins are shown by the main `catala` command and listed in `catala --help`
- exception catching at the toplevel has been refactored a bit as well; return
codes are normalised to follow the manpage and avoid codes >= 128 that are
generally reserved for shells.
