Moe - A powerful and user-friendly text editor

 [image of the head of a GNU] [ English | Espa駉l ]


GNU moe is a powerful, 8-bit clean, console text editor for ISO-8859 and ASCII character encodings. It has a modeless, user-friendly interface, online help, multiple windows, unlimited undo/redo capability, unlimited line length, unlimited buffers, global search/replace (on all buffers at once), block operations, automatic indentation, word wrapping, file name completion, directory browser, duplicate removal from prompt histories, delimiter matching, text conversion from/to UTF-8, romanization, etc.

Moe can easily edit thousands of files at the same time.

Moe uses ISO-8859-15 instead of UTF-8 because an 8-bit character set (combined with romanization if needed) can convey meaning safely and more efficiently than UTF-8 can.

UTF-8 is a great tool for tasks like writing books of mathematics or mixing Greek with Chinese in the same document. But for many other everyday computing and communication tasks, an 8-bit code like ISO-8859-15 is much more practical, efficient and reliable. There is no such thing as an "invalid" or "out of range" ISO-8859-15 character.

UTF-8 is fine for non-parsable, non-searchable documents that must look "pretty", but not so fine for things like filenames, configuration files or C++ source code. Invalid UTF-8 characters in filenames make archiving and filesystem operations unreliable. UTF-8 greatly hinders parsability (and may even become a security risk) by providing multiple similar-looking variations of basic alphabetic, punctuation, and quoting characters. UTF-8 also makes search difficult and unreliable. For example, searching for a word like "file" in an UTF-8 document may fail if the document uses the compound character 'fi' instead of the string "fi".

Moe tries to rationalize the keyboard commands. The Alt key is used for harmless commands like cursor movements and scrolling. The Control key is used for more "dangerous" commands like copying text blocks, deleting lines, or exiting. The Tab key is used for file name completion and also shows/hides the directory browser when moe asks for a file name to save or load. In any case, the unlimited undo/redo capability of moe makes very difficult to accidentally cause an irreparable damage to your files.

Moe uses the function keys so that the most frequent commands can be issued with only one finger. The function key F1 shows the online help, and F10 allows you to change the options. The online help and some experience with text editors is all you need to start using moe. Reading the manual is only required for more advanced uses of moe.
