TokenId

Generates the token type identifier for the given symbol.

There are two special cases:

If symbol is "", then the token identifier will be 0
If symbol is "\0", then the token identifier will be the maximum valid token type identifier

In all cases this template will alias itself to a constant of type IdType. This template will fail at compile time if symbol is not one of the staticTokens, dynamicTokens, or possibleDefaultTokens.

template TokenId (

IdType

alias staticTokens

alias dynamicTokens

alias possibleDefaultTokens

string symbol

) {

enum tokens;

enum id;

enum i;

enum id;

}

Examples

template tok(string symbol)
{
    alias tok = TokenId!(IdType, staticTokens, dynamicTokens,
        possibleDefaultTokens, symbol);
}
// num and plus are of type ubyte.
IdType plus = tok!"+";
IdType num = tok!"numberLiteral";
