git clone [email protected]:facebook/reason.git
cd reason
opam pin add -y reason .
If the compilation of Reason
does not succeed after pinning
merlin/merlin-extend
as described above, then a change to merlin
or
merlin-extend
may have broken Reason
(please file a Github Issue). We
should try to keep all three projects' master branches compatible with each
other.
