In semantic 1.4, a BNF file represented “Bovine
Normal Form”, the grammar file used for the 1.4 parser
generator. This was a play on Backus-Naur Form which proved too
confusing.
bovinate
A verb representing what happens when a bovine parser
parses a file.
bovine
lambda
In a bovine, or LL parser, the bovine lambda is a function
to execute when a specific set of match rules has succeeded in
matching text from the buffer.
bovine
parser
A parser using the bovine parser generator. It is an LL
parser suitible for small simple languages.
context
LALR
lexer
A program which converts text into a stream of tokens by
analyzing them lexically. Lexers will commonly create strings,
symbols, keywords and punctuation, and strip whitespaces and
comments.
LL
nonterminal
A nonterminal symbol or simply a nonterminal stands for a
class of syntactically equivalent groupings. A nonterminal
symbol name is used in writing grammar rules.
overloadable
Some functions are defined via
define-overload. These can be overloaded via
....
parser
A program that converts tokens to
tags.
tag
A tag is a representation of some entity in a language file,
such as a function, variable, or include statement. In
semantic, the word tag is used the same way it is used for
the etags or ctags tools.
A tag is usually bound to a buffer region via overlay, or
it just specifies character locations in a file.
token
A single atomic item returned from a lexer. It represents
some set of characters found in a buffer.
token
stream
The output of the lexer as well as the input to the
parser.
wisent
parser
A parser using the wisent parser generator. It is a port of
bison to Emacs Lisp. It is an LALR parser suitable for complex
languages.
