Operators comprised more than one symbols

[nsgnkhibdk2cls0f]

On lexer file, operators is defined as a string without any delimiter between the symbols like this:

-- Operators.
lex:add_rule('operator', token(lexer.OPERATOR, S('~!.,:;+-*/<>=\\^|&%?()[]{}')))

Then how could we handle operators comprised more than one symbols like >>, <<, >>>, <<<, ->, <>, :=,...?

As written, lexers will match your '>>', ':=', etc. one character at a time, giving the appearance of matching distinct operators. If you want to match multiple characters at once, use ordered choice: `P('<<') + '>>' + S('+-*/'`

Could you give me the full line as an example?

Yeah, I see. You have a markdown syntax error so I don't see your code formatted as code and my eyes are pretty bad. Sorry.

Same principle as with multi-line comments...

Please give me an example code.
