Description

YuPcre2 is a library of Delphi components and procedures that implement regular expression pattern matching using the same syntax and semantics as Perl, with just a few differences. There are two matching algorithms, the standard Perl and alternative DFA algorithm:

The Perl algorithm is what you are used to from Perl and j@vascript. It is fast and supports the complete pattern syntax. You will likely be using it most of the time.
DFA is a special purpose algorithm. If finds all possible matches and, in particular, it finds the longest. It never backtracks and supports partial matching better, in particular multi-segment matching of very long subject strings.

YuPcre2 has native interfaces for 8-bit, 16-bit, and 32-bit strings. Component wrappers are available for UnicodeString / WideString and AnsiString / Utf8String / RawBytestring:

The YuPcre2 RegEx2 classes descend from common ancestors which implement the core functionalities:

Match strings and and extract full or substring matches.
Search for regular expressions within streams and memory buffers. TDIRegExSearchStream descendants employ a buffered search within streams and files (of virtually unlimited size) and use little memory.
Replace full matches or partial substrings.
List full matches or partial substrings.
Format full matches or partial substrings by adding static or dynamic text.

Users familiar with the DIRegEx might be interessted in the differences between YuPcre2 and DIRegEx.

Pattern Syntax

YuPcre2 RegEx2 Workbench Application The YuPcre2 regular expression pattern syntax is mostly compatible with Perl. It includes the following:

Quoting
Escaped Characters
Character Types
General Category Properties for p and P
PCRE2 Special Category Properties for p and P
Script Names for p and P
Character Classes
Quantifiers
Anchors and Simple Assertions
Match Point Reset
Alternation
Capturing
Atomic Groups
Comment
Option Setting
Newline Convention
What R Matches
Lookahead and Lookbehind Assertions
Backreferences
Subroutine References (possibly recursive)
Conditional Patterns
Backtracking Control
Callouts

YuPcre2 RegEx2 String Processing

YuPcre2 can Replace, List, or Format regular expressions matches or any of its substrings, useful for text editors and word processors. Variable portions of the match can be included into the result text. The full match can be referenced by number, substrings also by name. The character to introduce these reference is freely configurable. FormatOptions allow to turn features on or off as required.

Replace returns the original subject string with matches replaced, similar to but more flexible than Delphi's StringReplace() function.
List collects all string matches into a single string. It extracts multiple phone numbers, e-mail addresses, or URLs, with a single call.

YuPcre2 RegEx2 MaskControls

The YuPcre2 RegEx2 MaskControls Demo ApplicationYuPcre2 includes two regular expression mask edits: TDIRegEx2MaskEdit and TDIRegEx2ComboBox. Both controls validate keyboard input against a regular expression. They work similar to Delphi's TMaskEdit, but more flexible and powerful.

The regular expression mask edits can:

accept / reject specific characters at determined positions;
allow / reject particular characters if they follow defined character(s);
restrict input text to begin / end with exact character(s);
flag incomplete text to show that more input is needed.

Examples: Numbers, number ranges, dates, phone numbers, e-mail addresses, URLs, currency, and more.

Workbench Application

The YuPcre2 RegEx2 Workbench helps to design and test regular expressions. It allows to set options, measure execution times, and to save and load settings for later use.

The YuPcre2 RegEx2 Workbench is available as

Design-Time Component Editor and
Standalone Application.

YuPcre2 v1.21.0 – 22 Nov 2023
Support Delphi 12 Athens Win32 and Win64.
Added pcre2_get_match_data_heapframes_size allow for finer control of the heap used when pcre2_match without JIT is used and the match_data might be reused.
Avoids overflow issues with the heap limit.
Restrict the interaction between ASCII and non-ASCII characters for caseless matching and items like d:
Added PCRE2_EXTRA_CASELESS_RESTRICT to lock out mixing of ASCII and non-ASCII when matching caselessly.
Added PCRE2_EXTRA_ASCII_{BSD,BSS,BSW,POSIX} and corresponding (?aD) etc in patterns.
Unicode has been updated to 15.0.0.
Add PCRE2_EXTRA_ASCII_DIGIT to allow [:digit:] to be kept on sync with d even in UCP mode.
Fix an invalid match of ascii word classes when invalid utf is enabled.
Update pcre2_compile to treat a nil pattern with zero length as an empty string.
Add support for limited-length variable-length lookbehind assertions, with default maximum length 255 characters (same as Perl) but with a function to adjust the limit.
Fixed a bug in pcre2_match in the code for handling the vector of backtracking frames on the heap, which caused a heap overflow if *LIMIT_HEAP restricted an attempt to extend to less than the frame size.
