Subject: | camlp4 and dirac notation |
I try to modify the ocaml syntax with camlp4 to add the Dirac notation |v >. Have you any solution ? I have tried with EXTEND expr : LEVEL "simple" [["|"; e=expr ;">" -> <:expr< ket $e$>>] ]; END;; but I have the following message |z>;; ^^ Parse error: [expr] expected after '>' (in [expr]) I can replace > by : but it is not the dirac notation.
