parsing
An algorithm or program to determine the
syntactic structure of ("to parse") a sentence or string of
symbols in some language. A parser normally takes as input
a sequence of tokens output by a lexical analyser. It may
produce some kind of abstract syntax tree as output. A
parser may be produced automatically from a grammar by a
parser generator such as yacc.
A parser is normally part of some larger program, like a
compiler, which takes the output of the parser and attempts
to extract meaning from it in some way, e.g. translating it
into another language.

parser generator
(foldoc) | parser generator
A program which takes a formal description of a grammar
(e.g. in BNF) and outputs source code for a parser which will
recognise valid strings obeying that grammar and perform
associated actions. Unix's yacc is a well known example.

recursive descent parser
(foldoc) | recursive descent parser
A "top-down" parser built from a set of
mutually-recursive procedures or a non-recursive equivalent
where each such procedure usually implements one of the
productions of the grammar. Thus the structure of the
resulting program closely mirrors that of the grammar it
recognises.
