-- Simple Regular expression matching
|
|
|

-- This package provides a simple implementation of a regular expression
|
|
|
|
-- pattern matching algorithm, using a subset of the syntax of regular
|
|
|
|
-- expressions copied from familiar Unix style utilities.
|
|
|
|
|
|
|
|
-- Note: this package is in the System hierarchy so that it can be directly
|
|
|
|
-- be used by other predefined packages. User access to this package is via
|
|
|
|
-- a renaming of this package in GNAT.Regexp (file g-regexp.ads).

|
|
|
|
|
|
|
|
-- The regular expression must first be compiled, using the Compile
|
|
|
|
-- function, which creates a finite state matching table, allowing
|
|
|
|
-- very fast matching once the expression has been compiled.
|
|
|
|
|
|
|
|
-- The following is the form of a regular expression, expressed in Ada
|
|
|
|
-- reference manual style BNF is as follows
|
|
|
|
|
|
|
|
-- regexp ::= term
|
|
|
|
|
|
|
|
-- regexp ::= term | term -- alternation (term or term ...)
|
|
|
|
|
|
|
|
-- term ::= item
|
|
|
|
|
|
|
|
-- term ::= item item ... -- concatenation (item then item)
|
|
|
|
|
|
|
|
-- item ::= elmt -- match elmt
|
|
|
|
-- item ::= elmt * -- zero or more elmt's
|
|
|
|
-- item ::= elmt + -- one or more elmt's
|
|
|
|
-- item ::= elmt ? -- matches elmt or nothing
|
|
|
|
|
|
|
|
-- elmt ::= nchr -- matches given character
|
|
|
|
-- elmt ::= [nchr nchr ...] -- matches any character listed
|
|
|
|
-- elmt ::= [^ nchr nchr ...] -- matches any character not listed
|
|
|
|
-- elmt ::= [char - char] -- matches chars in given range
|
|
|
|
-- elmt ::= . -- matches any single character
|
|
|
|
-- elmt ::= ( regexp ) -- parens used for grouping
|
|
|
|
|
|
|
|
-- char ::= any character, including special characters
|
|
|
|
-- nchr ::= any character except \()[].*+?^ or \char to match char
|
|
|
|
-- ... is used to indication repetition (one or more terms)
|
|
|
|
|
|
|
|
-- See also regexp(1) man page on Unix systems for further details
|
|
|
|
|
|
|
|
-- A second kind of regular expressions is provided. This one is more
|
|
|
|
-- like the wild card patterns used in file names by the Unix shell (or
|
|
|
|
-- DOS prompt) command lines. The grammar is the following:
|
|
|
|
|
|
|
|
-- regexp ::= term
|
|
|
|
|
|
|
|
-- term ::= elmt
|

-- term ::= elmt elmt ... -- concatenation (elmt then elmt)
|
|
|
|
-- term ::= * -- any string of 0 or more characters
|
|
|
|
-- term ::= ? -- matches any character
|
|
|
|
-- term ::= [char char ...] -- matches any character listed
|
|
|
|
-- term ::= [char - char] -- matches any character in given range
|
|
|
|
-- term ::= {elmt, elmt, ...} -- alternation (matches any of elmt)
|
|
|
|
|

|
|
-- Important note : This package was mainly intended to match regular
|
