Preprocessor is now a library installed by opam.
Replaced ligolang@gmail.com by contact@ligolang.org in opam files.
Reformatted some opam files.
Removed #line directive from preprocessor.
Added to the interface of ParserUnit.
Script messages.sh now checks the identity of .msg and .msg.old
to avoid undue warning about possibly different LR items.
The following preprocessing directives are supported
#define
#elif
#else
#endif
#endregion
#error
#if
#include
#region
#undef
Note: Because it is meant for LIGO, there is no error raised for
invalid preprocessing directives, as the symbol # is valid in
PascaLIGO (cons operator for lists). Also, the preprocessor may report an error on some weird but valid PascaLIGO contracts, like
const include : list (int) = list [1]
const l : list (int) = 0
