-- Summary of Pattern Matching Packages in GNAT Hierarchy --
|
||
|
|
------------------------------------------------------------
|
||
|
|
|
||
|
|
-- There are three related packages that perform pattern matching functions.
|
||
|
|
-- the following is an outline of these packages, to help you determine
|
||
|
|
-- which is best for your needs.
|
||
|
|
|
||
|
|
-- GNAT.Regexp (files g-regexp.ads/s-regexp.ads/s-regexp.adb)
|
||
|
|
-- This is a simple package providing Unix-style regular expression
|
||
|
|
-- matching with the restriction that it matches entire strings. It
|
||
|
|
-- is particularly useful for file name matching, and in particular
|
||
|
|
-- it provides "globbing patterns" that are useful in implementing
|
||
|
|
-- unix or DOS style wild card matching for file names.
|
||
|
|
|
||
|
|
-- GNAT.Regpat (files g-regpat.ads/s-regpat.ads/g-regpat.adb)
|
||
|
|
-- This is a more complete implementation of Unix-style regular
|
||
|
|
-- expressions, copied from the original V7 style regular expression
|
||
|
|
-- library written in C by Henry Spencer. It is functionally the
|
||
|
|
-- same as this library, and uses the same internal data structures
|
||
|
|
-- stored in a binary compatible manner.
|
||
|
|
|
||
|
|
-- GNAT.Spitbol.Patterns (files g-spipat.ads/g-spipat.adb)
|
||
|
|
-- This is a completely general pattern matching package based on the
|
||
|
|
-- pattern language of SNOBOL4, as implemented in SPITBOL. The pattern
|
||
|
|
-- language is modeled on context free grammars, with context sensitive
|
||
|
|
-- extensions that provide full (type 0) computational capabilities.
