malk-lexer
A unicode lexer for use as a first-pass when writing a parser.
The main function exported by this library is lex which takes a &str and a
table of valid symbols and converts them to a token tree.
The kinds of token recognized by the lexer are:
- Idents: A string starting with a
XID_Startcharacter followed by a sequence ofXID_Continuecharacters. - Whitespace: Any sequence of whitespace characters.
- Brackets: Any bracket character, it's corresponding closing bracket and the tokens in-between returned as a sub-tree.
- Symbols: Any string that appears in the symbol table provided to
lex - Strings: A string enclosed with either
"or'and which may contain escaped characters.
