There is a problem (reported by @dannywillems) with type-checking client values, and probably injections. It is because the new preprocessing pipeline introduces unpredictable intermediate filenames, impacting our auto-generated names for client fragments. To be fixed tomorrow. |

Should we try to provide a clean failure when reason is not installed ?
There was a problem hiding this comment.
Probably. We just need to look for refmt (the only thing we really need) at the time -reason is provided.
Edit: that turns out to be quite complicated, and the compiler itself prints a reasonable message about refmt failing. So, not a priority right now.

Nice work! |
When using refmt, we end up with intermediate filenames that break our identifier generation.

This PR provides very rough and mostly untested Reason support.
I added a
-reasonflag to our compiler wrappers. It is implemented by callingrefmtas a preprocessor.There is a new
basic.reasontemplate that uses Reason syntax.
