Where regular expressions differ to normal text is that they give special meaning to certain characters, allowing you to specify textual 'patterns' rather than just literal text. At the simplest level, a regular expression is no different to the text you type into the edit field of a Find dialog.

I think it is safe to assume that anyone who has used a modern computer will have used Find and/or Replace dialogs in more than one application that allows text processing, whether it is Notepad, a word processing program, or a web browser. The Find/Replace dialog is written from scratch - FindReplaceDlg.cpĪ Regular Expression is simply some text.You can open and re-save UNIX text files correctly - notepadreDoc.cpp.Unicode is supported - notepadreFile.cpp.You can open a text file bigger than 1 MB - notepadreView.cpp.You can re-open an existing file, something that does not work in the standard CEditView class - notepadre.cpp.You can drag and drop text to and from the edit window to and from other applications that support drag and drop - notepadreView.cpp.You can drop files as path/filename from Explorer by clearing Options->Drop Files - MainFrm.cpp.Line and column displayed in status bar - MainFrm.cpp, called from notepadre.cpp.If the file you are editing is changed by another process, you have the option of being asked if you want to reload - notepadreDoc.cpp.Find will wrap from bottom to top - or top to bottom, depending on search direction - if necessary - notepadreDoc.cpp.Dockable Find and Replace dialogs - MainFrm.cpp.GREP/Find in Files capability - FindInFilesDlg.cpp.Find and Replace in normal mode - notepadreDoc.cpp.Find and Replace using regex - notepadreDoc.cpp.This is much quicker than replacing every match in the edit window as you go along.Īs the development of Notepad RE progresses, more sophisticated features are being added. Replace All is improved compared to normal Notepad, as it builds a new text file in memory and replaces the entire text at once when it has finished.

Note that the intention is for the boost::regex library to eventually become part of the C++ Standard Library. The boost::regex library is used for regex support. The main feature is that you can Search and Replace optionally using regular expressions. Download source files, including executable - 309.7 KB.
