Verbosity of `--dump-tokens`

anqurvanillapy commented 5 years ago

Phew I'm just a goddamn Haskell newbie, hoowee. The verbosity of --dump-tokens option should be added for more convenient testing, e.g. a full verbosity (token type, token value, location) and a simple one (only token type and value).

The interface options are:
- --dump-tokens=full or --dump-tokens=simple
- -S for simple, -SS for full
- --dump-tokens for full, --dump-hide-pos for simple (this is originated from @ice1000, but I thought there could be conflicts here)

The current choice is the second one.

Currently a wrong verbosity level will ExitFailure with a stderr-based string, which is completely undesirable since showing help text is the best way to elaborate problems.

Added --dump-simple to dump tokens/AST in a concise way (without information like positions), and it can be used to straightly print anything about compiler frontend that eases the mind.
