10 In semantic 1.4, a BNF file represented ``Bovine Normal Form'', the
11 grammar file used for the 1.4 parser generator. This was a play on
12 Backus-Naur Form which proved too confusing.
15 A verb representing what happens when a bovine parser parsers a file.
18 In a bovine, or LL parser, the bovine lambda is a function to execute
19 when a specific set of match rules has succeeded in matches text from
23 A parser using the bovine parser generator. It is an LL parser
24 suitible for small simple languages.
31 A program which converts text into a stream of tokens by analyzing
32 them lexially. Lexers will commonly create strings, symbols,
33 keywords and punctuation, and strip whitespace and comments.
40 Some functions are defined via @code{define-overload}.
41 These can be overloaded via ....
44 A program that converts @b{tokens} to @b{tags}.
47 A tag is a representation of some entity in a language file, such as a
48 functin, variable, or include statement. In semantic, the word tag is
49 used the same way it is used for the etags or ctags tools.
52 A single atomic item returned from a lexer. It represents some set
53 of characters found in a buffer.
56 The output of the lexer as well as the input to the parser.
59 A parser using the wisent parser generator. It is a port of bison to
60 Emacs Lisp. It is an LALR parser suitable for complex languages.
