- 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
- Clearer (more detailed) error messages (see parser.messages, parser_driver.ml ->)
--> Parser_driver.ml : we're more precise and show all possible instructions to the user.
- Suggestions.ml : unimportant display changes + renaming
- 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
