ne - the nice editor for Mac

From Mneptok:

ne is a free (GPL'd) text editor based on the POSIX standard that runs (we hope) on almost any UN*X machine. ne is easy to use for the beginner, but powerful and fully configurable for the wizard, and most sparing in its resource usage. If you have the resources and the patience to use emacs or the right mental twist to use vi then probably ne is not for you. However, if you need an editor that:

• compiles without effort everywhere (or almost everywhere), is packaged for all Linux distributions, and ported to other operating systems (such as Mac OS X);
• is fast, small, powerful and simple to use;
• has standard keystrokes (e.g., copy is CTRL-C);
• uses little bandwidth, so it is ideal for email, editing through phone line (or slow GSM/GPRS/UMTS) connections;
• has a very compact internal text representation, so you can easily load and modify very large files...

then you should try ne.

Some of the features of ne are:

• three user interfaces: control keystrokes, command line, and menus; keystrokes and menus are completely configurable;
• syntax highlighting;
• full support for UTF-8 files, including multiple-column characters;
• the number of documents and clips, the dimensions of the display, and the file/line lengths are limited only by the integer size of the machine;
• simple scripting language where scripts can be generated via an idiotproof record/play method;
• unlimited undo/redo capability (can be disabled with a command);
• automatic preferences system based on the extension of the file name being edited;
• a file requester with completion features for easy file retrieval;
• extended regular expression search and replace a la emacs and vi;
• editing of binary files.
