Regular Expression Component Library for BCB4
-
Version
3.1
The Regular Expression Component Library is an easy to
use library for searching and/or replacing strings or
data in files using regular expressions. It supports
both VCL programming using the C++ Builder 4 IDE's RAD
programming model and non-VCL programming. Both
methods of programming support the properties,
methods, and events model C++ Builder.
It has flexible expression options to match any type
of regular expression syntax. There is extensive
documentation to explain its use and the library is
fully supported. The library is also fast and easy to
use and the header files automatically link in the
correct supporting libraries.
Regular expressions are a means of doing searching
based on patterns adopted from the UNIX idea of
regular expressions in various Unix tools.
The properties/methods/events model uses:
a) Properties for specifying a regular expression,
string to match, file specification ( with wildcards )
to match, flexible options for regular expression
syntax, flexible options for matching considerations,
and other properties to enhance matching capabilities.
b) Methods to match a string in numerous ways; the
entire string, the beginning of the string, anywhere
in the string, multiple exclusive matches in a string.
Methods to match file data; either a single match in a
file or multiple matches in a file. A method to change
data in a string or file based on format-like
replacement syntax which can use the actual data found
or one of its sub-expressions. A method for splitting
strings based on regular expressions.
c) Events to handle the gathering of specific data for
each of the matching methods. Most of the event
handlers gain access to what the expression matches as
well as to what each sub-expression of the expression
matches.
