# Quick Emacs (QEmacs)
|
|
|
|
Welcome to QEmacs! A small but powerful UNIX editor with many features
|
|
that even big editors lack.
|
|
|
|
## Quick Description
|
|
|
|
QEmacs is a small text editor targeted at embedded systems or debugging.
|
|
Although it is very small, it has some very interesting features that
|
|
even big editors lack:
|
|
|
|
- Full screen editor with an Emacs look and feel with all common Emacs
|
|
features: multi-buffer, multi-window, command mode, universal argument,
|
|
keyboard macros, config file with C like syntax, minibuffer with
|
|
completion and history.
|
|
|
|
- Can edit huge files (hundreds of megabytes) without delay, using a
|
|
highly optimized internal representation and memory mapping for large files.
|
|
|
|
- Full Unicode support, including multi charset handling
|
|
(8859-x, UTF8, SJIS, EUC-JP, ...) and bidirectional editing respecting
|
|
the Unicode bidi algorithm. Arabic and Indic scripts handling (in
|
|
progress). Automatic end of line detection.
|
|
|
|
- C mode: coloring with immediate update, auto-indent, automatic tags.
|
|
|
|
- Shell mode: full color VT100 terminal emulation so your shell works exactly
|
|
as you expect. Compile mode with colorized error messages, automatic
|
|
error message parser jumps to next/previous error, works with grep too.
|
|
The shell buffer is a fully functional terminal: you can run qemacs,
|
|
vim or even emacs recursively!
|
|
|
|
- Input methods for most languages, including Chinese (input methods
|
|
come from the Yudit editor).
|
|
|
|
- Binary and hexadecimal editing mode with insertion and block commands.
|
|
Unicode hexa editing of UTF-8 files also supported. Can patch binary files,
|
|
preserving every byte outside the modified areas.
|
|
|
|
- Works on any VT100 terminal without termcap. UTF-8 VT100 support
|
|
included with double width glyphs.
|
|
|
|
- X11 support. Supports multiple proportional fonts at the same time
|
|
(like XEmacs). X Input methods supported. Xft extension supported for
|
|
anti-aliased font display.
|
|
|
|
- Bitmap images are displayed on graphics displays and as ASCII colored text
|
|
on text terminals, which is handy when browsing files over an ssh connection.
|
|
(QEmacs uses the public domain [`stb_image`](https://github.com/nothings/stb/blob/master/stb_image.h) package for image conversions.
|
|
|
|
## Building QEmacs

|
|
|
* Launch the custom configuration script `./configure`. You can list the

possible options by typing `./configure --help`.
