Function: semantic-lex-token

semantic-lex-token is a macro defined in lex.el.gz.

Signature

(semantic-lex-token SYMBOL START END &optional STR)

Documentation

Create a lexical token.

SYMBOL is a symbol representing the class of syntax found. START and END define the bounds of the token in the current buffer. Optional STR is the string for the token only if the bounds in the buffer do not cover the string they represent. (As from macro expansion.)
