A string” contained an extraneous closing parenthesis. Use: RegexBuddy incorrectly escaped backslashes in the JavaScript /regex/ notation. Backslashes only need to be escaped when writing a regex as a string literal (dubbed “alternative” notation by RegexBuddy). RegexBuddy 1.2.0 – 1 June 2004 New features: Create: Support for .NET-style named capture (?group) and named backreferences \k. .NET-style named capture is automatically converted into Python-style named capture when the regular expression is implemented in a code snippet on the Use page for PHP/preg, Python or PCRE. Create: Support for Python-style named capture (?Pgroup) and named backreferences (?P=name). Python-style named capture is automatically converted into .NET-style named capture when the regular expression is implemented in a code snippet in a .NET language on the Use page. Replace: Support for .NET-style named references ${name} and Python-style named references \g in the replacement text. Use: Function to extract the text matched by a named capturing group for C#, VB.NET, Delphi for .NET and PCRE. Use: Python language support Improvement: Use: Selecting another language now keeps the same function selection, if it is available in the newly selected language Bug fix: Use: PHP preg code snippets used “preg” instead of “preg_match” to test if a regex matches a string RegexBuddy 1.1.0 – 17 May 2004 New features: RegexBuddy can now automatically generated code snippets for Delphi for .NET Bug fixes: Test: Changed the shortcut for Find Next from Alt+N to Alt+X. Alt+N will launch a new instance of RegexBuddy. Test: Find First and Find Next now scroll the test subject to bring the match into view. RegexBuddy 1.0.1 – 10 May 2004 The release of RegexBuddy has gone very smoothly. No serious issues have been reported. A few minor corrections are made in version 1.0.1. Improvements: Alt+S shortcut to send a regex to the application RegexBuddy was invoked from Use: The PowerGREP button now works like the Send To button when RegexBuddy was activated from within PowerGREP. If RegexBuddy was not launched from PowerGREP, the Use button starts a new instance of PowerGREP via the command line. Bug fixes: Library: Delete button was not disabled when the library is read only Preferences: The options to show spaces and paragraphs markers did not have any effect Sending a regex from an application to RegexBuddy now properly updates the Create, Test and Use tabs RegexBuddy 1.0.0 – 3 May 2004 First public release of RegexBuddy.

Regex. RegexBuddy 3.6.0 – 25 October 2012 Improvements: Test: Open URL window should allow right-click Paste. Windows 8: Uninstall shortcut is no longer pinned to the start screen by the installer (but it won’t unpin any shortcuts that were previously pinned). Bug fixes: GREP: Trying to open a RegexBuddy GREP file sometimes failed with a false error saying the file is not a valid RegexBuddy GREP file. List All: Clicking the List All button makes RegexBuddy forget which capturing group you had it list matches for. Test: Debug Here and Debug Till End triggered an “invalid class typecast” error if the test subject editor was in hexadecimal mode. Test: If a regular expression contained an inverted range with a \xFF escape and the active flavor does not support inverted ranges then RegexBuddy would continue to complain about the inverted range even after you corrected the regular expression. Test: Regular expressions with character classes with just a single NULL byte (e.g. [\x00] or [^\x00]) caused RegexBuddy to behave incorrectly. Windows 8: Toolbar combo boxes did not properly display their drop-down arrows. RegexBuddy 3.5.5 – 22 March 2012 Improvements: Test: Update Automatically is preserved between RegexBuddy sessions even when not preserving test data. Test: Update Automatically switches to the last used Match/Replace/Split testing command when switching between Match/Replace/Split modes. Bug fixes: GREP: If the regex consisted of nothing but a case sensitivity modifier and literal text such as (?i)sometext then the case sensitivity modifier was ignored. Installer: The default folder for portable installations created via the installation program was “RegexBuddy 3” with a space before the number. This caused portable installs of PowerGREP, EditPad Pro, and RegexMagic on the same device to fail to locate RegexBuddy when you tried to invoke RegexBuddy from these products. Paste: PHP preg strings with regular expressions containing doubly escaped forward slashes that are also delimited with forward slashes were not pasted correctly. Use: \‘ was translated into \A instead of a literal ‘ when the source flavor does not support \‘ to match the start of a string. RegexBuddy 3.5.4 – 4 November 2011 Improvement: Installer: Create portable installation without admin rights. Bug fixes: Copy/Use: The regex \\n (literal backslash and literal n) was not converted properly when coping C-style or Java strings or generating C or Java code snippets. Preferences: Line numbers were always shown or hidden in the test results depending on the line number setting for the test subject, even when the test results are for a test command that ignores the line number setting. RegexBuddy 3.5.3 – 22 June 2011 Bug fix: Create Portable Installation item in the Help menu was broken in 3.5.2. RegexBuddy 3.5.2 – 17 June 2011 Improvements: GREP: Edit with EditPad command now works with EditPad Lite 7 and EditPad Pro 7. It still works with EditPad Pro 4, 5, and 6 too and gives preference to these versions if you use them alongside EditPad Lite or Pro 7. GREP: Loading a grep action should add the regex

Easily Use Regular Expressions in Your C# Source Code .NET’s Regex Support Microsoft’s .NET provides a solid implementation of regular expressions. The original .NET Framework, .NET Core, and .NET 8.0 all implement the same regex flavor. You can use it in your C# application simply by importing the namespace System.Text.RegularExpressions. RegexBuddy makes it very easy to use the power of regexes in your C# source code. See How Easy Coding with Regexes Can Be First, use RegexBuddy to define a regex or retrieve a regexp saved in a RegexBuddy library. Rely on RegexBuddy’s clear regex analysis, which is constantly updated as you build the pattern, rather than dealing with the cryptic regex syntax on your own. Detailed help on that syntax is always only a click away. If you copied a regex written for another programming language, simply paste it into RegexBuddy, select the original language, and then convert the regex to the .NET flavor used by C#. If you created a new regular expression, test and debug it in RegexBuddy before using it in your C# source code. Test each regex in RegexBuddy’s safe sandbox without risking precious data. Quickly apply the regex to a wide variety of input and sample data, without having to produce that input through your application. Finally, let RegexBuddy generate a source code snippet that you can copy and paste directly into Visual Studio or whichever IDE or C# code editor you use. Just choose what you want to use the regex for, and a fully functional code snippet is ready. You can change the names of variables and parameters to suit your naming style or the current situation, which RegexBuddy automatically remembers. Don’t bother trying to remember which classes to use or which methods to call. And don’t worry about properly escaping backslashes and quotes. Just tell RegexBuddy what you want to do, and you will get the proper C# code straight away. Anything can be done: testing a string for a match, extracting search matches, validating input, search-and-replace, splitting a string, etc. Choose whether to create a reusable regex object for best runtime performance, or whether to use a one-line convenience function for maximum source code readability. RegexBuddy wraps its code with the proper try..catch statements, so you will never get unhandled exceptions out of the blue. RegexBuddy also has specific support for the Visual Studio 2012 (and later) IDE. Since 2012 the IDE also uses the .NET regex flavor. But it does not support any regex options other than case insensitivity, which is on rather than off by default. RegexBuddy takes care even of such minor details. Create and test your regex in RegexBuddy with the same limitations as the IDE, or create it for C# first and then have RegexBuddy convert it for use in the Visual Studio IDE. “I am a .Net developer with a decent working knowledge of regular expressions. I have found RegexBuddy to be an incredible tool because its debugging features allow me to tinker with

JavaScirpt search-and-replace snippets did not convert \1 in the replacement text into $1. Vista: Attempting to invoke RegexBuddy from within EditPad Pro, PowerGREP or AceText would cause the invoking program to lock up, waiting for RegexBuddy to respond. Eventually the calling program would time out and say RegexBuddy is not installed. RegexBuddy 2.3.0 – 18 September 2006 New feature: Generate code snippets in REALbasic on the Use tab. Improvement: RegexBuddy will now auto-detect Unicode files without a byte order marker when opening them on the Test tab or searching through them on the GREP tab. Bug fix: JavaScript code snippet to search-and-replace using a regex object didn’t put the /g flag in the correct spot. RegexBuddy 2.2.3 – 18 July 2006 The GREP button did not work in version 2.2.2. RegexBuddy 2.2.2 – 8 July 2006 New features: Use: “comment with regex tree inside region” for C#, VB.NET and Delphi for .NET. This style of comment can be collapsed in Visual Studio and most other C# and VB.NET code editors. Use: C#/VB.NET/Delphi.NET code snippet to search-and-replace through a string, adapting the replacement to each match using a MatchEvaluator. Improvements: Library: If RegexBuddy is launched from another application and the Send button is clicked without a regular expression being entered at the top in RegexBuddy, send the regex from the library to the application. Use: Adapt PHP preg regex delimiters to the regular expression, i.e. don’t use / as a delimiter when the regular expression contains / characters, so they don’t have to be escaped. Use: The default parameter names for Java source code snippets now start with lowercase letters. Bug fixes: Copy/Use: RegexBuddy incorrectly escaped \ characters in the replacement text in Perl s/// operators. Create: Clicking on a node in the Create tree selected one character too many in the regular expression. Create: If the regular expression contains an atomic group or option group that is repeated, the regex tree did not show a node indicating the quantifier. Create: The Use Backreference item in the Insert Token menu caused an Access Violation error (version 2.2.1 only). GREP: None of the items in the drop-down menu of the Open button on the GREP tab worked. GREP: Opening a previously saved grep action does not update the items available in the Target list if opening the action requires RegexBuddy to switch from the Match to the Replace tab or vice versa. Regex: Doubly nested repeating capturing groups caused RegexBuddy to hang or crash when attempting to try the regex on the Test page. Regex: If the regular expression started with a literal character, and that literal character was repeated a fixed number of times with the {n} operator, and the following regex token is another literal character, then RegexBuddy incorrectly expanded the quantifier when applying the “literal start” optimization. E.g. a{2}b would fail to match aab while \w{2}b, a{2}\w and a{2,3}b all matched properly. RegexBuddy optimized a{2}b into (?:aab){2} instead of aab. Note that not all regular expression engines optimize a{2}b

PCRE does not support finite repetition inside lookbehind. PCRE only supports alternation of strings of different lengths. Previously, RegexBuddy allowed finite repetition for PCRE. Flavors: Perl and Python allow alternation inside lookbehind if all the strings have the same length. Previously, RegexBuddy did not allow any alternation inside lookbehind for Perl and Python. Insert Token, Character Class: Literal hyphens in character class ranges were not escaped. Menu and toolbar icons were gray or black squares on Windows 98, ME, and 2000 (3.4.0 only). Portable installations of RegexBuddy saved the test subject on the host PC instead of on the portable device when the option to preserve the test data was turned on in the Preferences. Regex: POSIX equivalence classes for characters other than plain A to Z such as [[=à=]] were not parsed correctly. RegexBuddy failed to close if it could not save its state (e.g. because it’s running from a write-protected device). Test: Atomic groups as the first token inside a needless non-capturing group lost their “atomic” property causing RegexBuddy to find matches when it shouldn’t. Test: Column headers in the test results aren’t displayed correctly when the default language for non-Unicode applications is set to Chinese. RegexBuddy 3.4.0 – 5 August 2009 New feature: Create: RegexMagic button to invoke RegexMagic to generate a regular expression or to insert a partial regular expression generated with RegexMagic. Requires RegexMagic 1.0.2 or later. Improvements: Create: When flagging \‘ and \’ in flavors that don’t support these as anchors, indicate how to match them as a literal character in addition to saying such anchors aren’t supported. Paste: XML character entities such as and are now interpreted when pasting a regular expression or replacement text from XML. Bug fixes: Create: Negated character classes containing only a single hexadecimal escape \uFFFF or \xFF were not indicated as being negated in the regex tree. Create: Subtracted character classes containing only a single shorthand were not indicated as being subtracted in the regex tree. Flavors: GNU BRE regexes using \| for alternation were not converted correctly on the Use tab. Forum: When detecting Internet Explorer proxy settings, RegexBuddy now correctly interprets proxy server settings that include an http:// protocol specification. GREP: Backup drop-down list was not enabled when RegexBuddy started with preserved grep settings that create target files. GREP: F9 showed the GREP drop-down menu instead of running a preview when RegexBuddy was in Replace mode. GREP: The “single *.~*” backup naming style did not work, causing RegexBuddy not to update any files. Regex: A contrived regular expression such as (?::?(?:(?:\#?)\s*(?:s)*)+) with groups nested multiple levels deep with everything inside the groups being optional caused RegexBuddy to crash. Regex: Regexes that consisted solely of lookbehind statements failed with an access violation error. Test: A regular expression that ends with a vertical bar did not find a zero-length match at each character position as it should. Test: Find First would skip over a zero-width match at the start of the test subject, selecting the second match instead,
