Questions tagged [syntax-table]

is an Emacs Lisp data structure in which each character's syntactic role is defined. Other Emacs facilities, such as font lock, navigation, parsing, etc., scan these syntax tables to determine where words, symbols, and other syntactic constructs begin and end. Syntax tables are unique to every major mode. They are customizable and even overridable with text properties.
