- We're able to say from the parser what the user could have written. It may not be complete due to the acceptable function of Menhir : it is only an indication given to the user (and not intended to be an adaptive documentation)
- .mli file added : module interface for suggestions
- Add a test that provides a typographical or a logical error.
- Documentation and type / name changes for suggestions
- suggestions.ml : improve details + algorithm implementation (see @Altgr reviews) + comments
- suggestions implementation : since we want to keep the same structure to display suggestion messages, Suggestion is no longer a formatted string but a string list. The goal is to have a similar formatted string for each suggestion, no matter what the error message is.
--> This involves changes to suggestions.mli, compiler/desugared/from_surface.ml (most important one) and compiler/surface/parser_driver.ml
- 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.
