instead of a closed set of languages. I also removed the offsets: I simply use the current region to determine whether the preprocessing directie starts at the beginning of a line. I also removed scanning line indicators, to make the lexer simpler.
A preprocessor a la C# in OCaml
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
