Adding support for the bitstring module

[xguerin]

The bitstring module is a lifesaver for those working with bit strings. Unfortunately, it introduces a syntax extension bitmatch that is not supported by Merlin. How much trouble would it be to support it ?

I will have a look during the week, but at this point it's very unlikely that we will implement support for a new camlp4 extension.
People should consider using PPX (if you have time, you could contribute a ppx extension for bitstring, match%bitstring ... with sounds fine), which is supported by merlin.

I created an issue on bitstring's upstream.

Thanks, although the bitstring project does not seem very active. I'll work on it. Side question: how do you specify PPX to merlin ? With EXT ? I am trying withppx_metaquot, but it does not seem to be working.

No, just add the package with PKG.
EXT is to be used only for camlp4 extensions.

I'm closing this issue as won't fix btw.
bitstring should switch to using ppx.
