Note
New users should consider using MicroEmacs 2025
which has better support for Unicode in terminals, more modern font support on X11 and as well adds
SSL (https) support. New development will take place mainly in the MicroEmacs 25 project.
Here we will add smaller improvements and bugfixes.
Currently FreeBSD, Linux 32 bit, Linux kernel 4 builds and Windows Cygwin builds are only available for
MicroEmacs 09, so the binaries for this project here which you find below.
Extensible Terminal and GUI text editor with Emacs feeling coming as a small, single file executable for Windows, Linux, MacOS and FreeBSD.
Main features - Pros:
- small!! and fast!!
- character based user interface in terminal and in GUI mode working the same way
- Windows, Windows Cygwin, Linux, macOS and FreeBSD versions all working the same file
- single file installs possible (2.5MB-4MB file size)
- Emacs like (default) or CUA key bindings available
- menu entries for all main functions (Esc = in Terminal mode for menu)
- extensible programming language
- themes, customizations, templates, snippets menu or GUI accessible
- for its size the text editor with most features without being bloated
Cons:
- No Unicode (but full ISO and Windows encoding support) - you can type usually all the keys from your keyboard
- No softwrap (but automatic wrap is available)
This is a fork of Jasspa MicroEmacs forked from https://github.com/vitalyster/microemacs. It is an extended version of the MicroEmacs 2009 release which was the last official release available at the website http://www.jasspa.com.
Schemes
Left the Ayu Light theme which is defined in the file schemeal.emf and right the popular "Dracula" theme which is defined in the file schemedr.emf. See the folding feature for Markdown, in the image below (Dracula theme) the section build is folded by the indicated three dots:
Left Greek Lipum text in a ME terminal session as well displaying the menu. Please note, that to use extended char sets you need for MicroEmacs 09 the luit application. On the right the Solarized Light theme showing R documentation for the function pam in the cluster package.
Executables can be of three types:
- mec(b) - console only (around 600kb without macro files)
- mew(b) - X11/Windows only (around 630kb without macro files)
- mecw(b) Terminal and X11 enabled - for Mac with XQuartz and for Linux with X11 (650kb w/o macro files)
The bfs executables (mecb, mewb and mecwb) have as well all macro files, the internal help file and the American dictionary embedded (file size around 2.5-4.0Mb depending on the platform). For simplicity reasons all downloads on the release page are bfs-builds.
In comparison to the version at the Jasspa website it contains the following changes / extensions:
- improved terminal mode for suspend-emacs with using alternative terminal buffer (thanks to Steven Phillips)
- basic git support with commands to add, commit and get status of files etc
- easier addition of own user templates with interactive template selection using the command "insert-template"
- support for Go, Tcl and Python for linters and formatters, other programming languages on request
- more schemes (themes) Ayu Light and Dark, Dracula, Solarized Light and Dark, and Tango Light and Dark
- editor themes can be directly loaded from xrdb theme files like these from the iTerm2-Color-Schemes repo
using the xrdb-scheme macro - better support for TTF-fonts on X11 and their ISO-8859-1 .. 15 and Windows-Cp1252 encodings
- easier font-selection on X11 using xfontsel from the user-setup or using the change-font-xfontsel macro
- easier font resize on X11 (Mac and Linux) and Windows using Ctrl-Plus and Ctrl-Minus keys
- documenting ME macro functions as well with basic Markdown syntax - see define-help help page
- much improved Markdown mode (folding, template file, syntax hilghlighting, outline in item list, embedding Tcl, Python, R and Dot code in fences with syntax highlight)
- improved Python, Shell, Tcl and R support with folding, item-list and abbreviations
- improved CUA bindings and jeany-bindings where CUA bindings (C-s, C-x, C-v etc are prefixed with C-j so that still all Emacs bindings are available
- AppImage for easy install on Linux systems
- Linux (Ubuntu 20, 22, 24), Windows, Windows Cygwin, Darwin 21, 22, 23, 24 builds using Github actions
- Windows builds using cross compilation on Ubuntu with Github actions on Windows Visual Studio build as Github action
- updates on documentation
- fix for str_errlist[errno] by replacing it with strerror(errno) on Linux x64 Fedora with gcc 10.3
- fix for hang on error bug if using the -n command line switch
- fix for frame resize on X11 if the font changes (thanks to Steven Phillips)

Installation
Unix systems
For Linux, MacOS, FreeBSD, Cygwin-Windows and Msys-Windows the following lines might work to install or to update the MicroEmacs 09 executable:
bash -c "$(curl -fsSL https://github.com/mittelmark/microemacs/releases/latest/download/install.sh)"
source ~/.bashrc ## for the current session update the PATH settings
mecb -V
This line requires the tools curl and unzip to be installed on your Linux, FreeBSD or Windows Cygwin/Msys system.
You can then start either the terminal version with the command mecb arguments or the
X11/Windows version with mewb arguments.
On Cygwin Windows you might as well need to install libxt6 for instance on MobaXterm you write apt install libxt6 to
run the mewb executable.
To get the colored terminal version you should activate TermCap colors in Tools-User Setup-Platform and run the mecb version like this:
TERM=xterm mecb ...
To avoid typing this and for proper rendering of non ISO-8859-1 characters
using the luit tool on a Unix terminal with UTF-8 support it is usually done by performing an
alias in your .bashrc or your .zshrc like this:
alias mec="TERM=xterm luit -encoding ISO8859-15 mecb"
alias mew="mewb"
If you like to have Windows CP1252 character support you can as well use the following mec alias:
alias mec="TERM=xterm luit -encoding CP1252 mecb"
The number of fonts which MicroEmacs can use per default is a little bit restricted as it uses the X11 font system For a long story look here: https://www.linuxdoc.org/HOWTO/XWindow-User-HOWTO-7.html
There is as well a little installer script for the X11 version of MicroEmacs
which links your already installed existing monospaced TrueType fonts into
your personal folder ~/.config/share/fonts and then indexes them there using
the mkfontscale tool. Further the script downloads a few more free fonts like
"Source Code Pro", "Dejavu Sans Mono" and "Ubuntu Mono" into this folder and
the indexes these fonts as well.
You can run this script like this;
bash -c "$(curl -fsSL https://github.com/mittelmark/microemacs/releases/latest/download/install-fonts.sh)"
Therafter you might update the fontpath like this;
xset +fp ~/.local/share/fonts
xset fp rehash
To add the fontpath at every time you start your system automatically you might need to add these two lines as an autostart entry for your desktop/window manager.
Here an example on what you can add to your .bashrc to add that font path after you logged in:
xset q | grep -A 2 Font | grep -q /.local/share/fonts || xset +fp ~/.local/share/fonts && xset fp rehash
Tip
Unfortunately some recent Linux systems like Red Hat Enterprise 10 or Alma Linux 10 do not
allow anymore to install these old X11 tools like xset. Workaround: you have in this case
install the fonts with sudo privileges in the existing X11 font directories. On a
Alma Linux 10 system for instance I copied as sudo the indexed fonts (using
mkfontscale) into the directory /etc/X11/fontpath.d/fonts and they are then available as well
for other older X11 applications.
Install Spelling Dictionaries
The spelling dictionaries for several languages can be downloaded manually and placed into the MicroEmacs $user-path folder from the release page of v0.9.0
or by for Unix systems or Microsoft Cygwin using a bash install script like this:
bash -c "$(curl -fsSL https://github.com/mittelmark/microemacs/releases/latest/download/install-dict.sh)"
Windows 10/11
Caution
You can't run MicroEmacs 09 or MicroEmacs 25 currently easily on the same machine. If you installed ME 25 and it works fine, stick with it. MicroEmacs 09 is just thought as a fallback option when ME 25 does not work as expected. In this case please fill an issue item on the ME 25 project page. The Windows Cygwin binaries can however be used in parallel to ME 25 Windows builds. Cygwin binaries are installed as described above using the Bash install.sh script.
For a Windows installation you can do the following after opening a Powershell Terminal and executing the following four lines of code:
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
Invoke-RestMethod -Uri https://github.com/mittelmark/microemacs/releases/latest/download/install-windows.ps1 | Invoke-Expression
mewb -V
mecb -V
The executable mewb is then in the PATH ($env:LOCALAPPDATA) and you can run it from any terminal window or after pressing the Win-r combination and then typing mewb in the run command line. There should be as well a start menu entry for the "MicroEmacs 09" executable.
Compilation
Debian Systems
Below you find links to prebuild binaries. If you prefer to compile the code yourself here are the required commands for a Debian or Debian derived system like MX Linux, Linux Mint or Ubuntu system:
Let's first build a console version:
### install packages sudo apt install git build-essential libz-dev libncurses-dev ### fetch repo git clone https://github.com/mittelmark/microemacs.git cd microemacs ### builds the bfs executable for making stand-alone mecb and mewb etc make -f linux32gcc.gmk bfs/bin ### builds standalone mecb executable (Terminal) make -f linux32gcc.gmk mecb
You should now have files like mec-VERSION-PLATFORM.bin (VERSION and
PLATFORM are just placeholders) which are standalone executable which have
included all macro files, the help file and the American dictionary and which
can be run in the terminal by simply executing it.
Try the version flag:
./mecb-VERSION-PLATFORM -V
Now lets build afterwards a GUI only (mewb) and a combined GUI/terminal version (mecwb) which can be run both as a terminal and as a X11 application.
### install packages for X11 build sudo apt install libxt-dev ### builds standalone mew executable (GUI) make -f linux32gcc.gmk mewb ### builds combined standalone mecw executable (Terminal and GUI) make -f linux32gcc.gmk mecwb sudo apt install x11-utils # xfontsel, xlsfonts - better font selection sudo apt install xfonts-utils ## mkfontscale for using ttf fonts sudo apt install luit ## unicode support in the terminal sudo apt install xclip ## for better clipboard support sudo apt install wl-clipboard ## if running Wayland desktop or window manager for copy and paste
Red Hat Systems
Here the steps required to compile the editor on Red Hat compatible systems like CentOS
or AlmaLinux, For Fedora builds replace yum with dnf:
### install make, unzip, gcc sudo dnf install make zip unzip gcc zlib-devel ncurses-devel git ### fetch repo git clone https://github.com/mittelmark/microemacs.git cd microemacs ### builds the bfs executable for making stand-alone mecb and mewb etc make -f linux32gcc.gmk bfs/bin ### builds standalone mecb executable (Terminal) make -f linux32gcc.gmk mecb ### install X11 developer files sudo dnf install libXt-devel ### builds standalone mew executable (GUI) make -f linux32gcc.gmk mewb ### builds combined standalone mecw executable (Terminal and GUI) make -f linux32gcc.gmk mecwb ### for more fonts and better font selection sudo dnf install xorg-x11-apps ## xfontsel sudo dnf install xorg-x11-fonts* ## Lucidatypewriter, Adobe courier sudo dnf install wl-clipboard # if running Wayland for copy and paste support
If you do not want to build these executables yourself you can just download pre-build executables (see below).
Arch Systems like Manjaro Linux
Here the steps required to compile the editor on Arch based systems like Manjaro.
### install make, unzip, gcc sudo pacman -S make gcc ncurses zlib luit xorg-xfontsel ttf-fira-mono ### fetch repo git clone https://github.com/mittelmark/microemacs.git cd microemacs ### builds the bfs executable for making stand-alone mecb and mewb etc make -f linux32gcc.gmk bfs/bin ### builds standalone mecb executable (Terminal) make -f linux32gcc.gmk mecb ### install X11 developer files seems not required on Manjaro ### builds standalone mew executable (GUI) make -f linux32gcc.gmk mewb ### builds combined standalone mecw executable (Terminal and GUI) make -f linux32gcc.gmk mecwb ### for more fonts and better font selection sudo pacman -S xorg-xfontsel ttf-fira-mono ### xfontsel and CP1252 enabled font xset fp rehash ## update the fontpath settings to the current session
If you do not want to build these executables yourself you can just download pre-build executables (see below).
Cross-compilation on Linux for Windows:
You need the Mingw32 GCC compiler and the Zip library. Here an install on Fedora:
sudo dnf install mingw32-gcc mingw32-zlib
On Debian systems like Ubuntu:
sudo apt install build-essential mingw-w64 gcc-mingw-w64-i686
sudo apt install libz-mingw-w64 libz-mingw-w64-dev
sudo apt install desktop-file-utils
Thereafter you might execute make -f linuxmingwgcc.gmk mecb mewb to get all
binaries for Windows on your Linux machine.
Compilation on Cygwin Windows
Here are the steps to compile on Cygwin Windows if using the apt-cyg / cyg package manager.
For Windows I used MobaXterm version 25.2 for the compilation.
apt install git gcc-core make unzip git libncurses-devel libXt-devel zlib-devel
git clone https://github.com/mittelmark/microemacs.git
cd microemacs
## Or if git is not working or not installed (what was true for MobaXterm 25.2):
## wget https://github.com/mittelmark/microemacs/archive/refs/heads/master.zip
## unzip master.zip && cd microemacs-master
make -f cygwin.gmk bfs/bin ## bfs tool for standalone MicroEmacs files
make -f cygwin.gmk mecb ## console version
make -f cygwin.gmk mewb ## X11 version
make -f cygwin.gmk mecwb ## X11 and console version
## for better font support
apt install xfontsel mkfontscale xset
FreeBSD and GhostBSD
If you install gcc on FreeBSD it comes with the ncurses libraries already included so for the compilation you install the following tools:
sudo pkg install gcc sudo pkg install Xorg libX11 ### GhostBSD as well: sudo pkg install -g 'GhostBSD*-dev'
Therafter you should be able to compile the application using the Makefile in the microemacs root project folder.
### compile the barebone executables make -f freebsd.mak bfs/bin mec mew mecw ### compile the standalone executables make -f freebsd.mak mecb mewb mecwb
The Makefile has the extension mak as it can use the default make
utility from FreeBSD and does not need the gnu-make version gmake.
Download Prebuild MicroEmacs Executables (v09.12.26b2)
This release provides the following new features in comparison to v09.12.25:
- bugfix on Unix for cut and paste (beta2 fix)
- support for Ubuntu/Debian with Kernel 7.0 (beta2 addition)

Installation:
Installation of these executables is easy. Make them executable on Unix platforms and move them to a folder belonging to your PATH variable. Windows users should just copy them as well to such a folder.
Just download an executable for your platform which matches as closely as possible your operatig system. For instance for Fedora 39, you download the binaries for Fedora 38. On Unix systems you make the file executable (chmod 755 filename) and rename it for instance to me, then copy it to a folder belonging to your PATH. Therafter you can run the me executable. The first thing you have to do is to select the right keyboard configuration after starting your first session. Choose the menu entry "Tools -> User Setup" and then "Keyboard" the Start-Up tab.
Ubuntu builds should be usable on Debian and derived distros, such as Linux Mint or MX Linux compatible. AlmaLinux builds should be CentOS and RHEL compatible. Fedora builds can be probably only used on Fedora without problems.
Build for other platforms might be provided if requested using the issues link on this repository.
Msys2 Windows Terminal
I usually recommend the Msys2 environment for developers if they have to use the Windows operating system. As the provided Windows build is a native Windows build, the console version of Me09 must be started via the cmd Terminal on Windows. You should use in this case a bas function like this code below which should be added to your .bashrc.
### add this to your .bashrc
### we assume that you copied the windows executables
### to the bin folder in your msys HOME
function me {
if [ $1 == "-n" ]; then
## running terminal version
shift 1
cmd //C `cygpath -wa ~/bin/mec-windows.exe` "${@}"
else
`cygpath -wa ~/bin/mew-windows.exe` "${@}" &
fi
}

dictionaries download the dictionary files for your language from the relase
page:
https://github.com/mittelmark/microemacs/releases:
and place these files in your personal user folder ~/.jasspa on Linux for
instance. Then use "Tools -> User Setup -> Language settings" to switch the
dictionary.
You should download the files for you language and place them into the ME config folder, usually ~/.jasspa, in your home directory. On Windows check user-setup where the ME user folder is.

BFS executables
The BFS executables can be used to extract the binary and the macro files from the MicroEmacs executables and to build you own executables with other dictionary files, other user templates, or additional macro files. So you can customize your MicroEmacs version.
Here an example on how to do so:
### get the German dictionary files wget http://www.jasspa.com/spelling/ls_dede.zip ### extract the arcive from the file me-linux.bin bfs -x jasspa me-linux.bin ### add new spellings cd jasspa/spelling unzip ../../ls_dede.zip ### create the new file bfs -a me-linux.bin ./jasspa -o me-linux2.bin ### test the terminal MEPATH="" TERM=rxvt ./me-linux2.bin -n ### in case of problems with the backslash key try MEPATH="" TERM=xterm ./me-linux2.bin -n
Luit and Abduco for using ME on Unicode terminals
Luit and Abduco
To use the full ISO-8859-XX or Windows-CP125X character sets on Unicode terminals you can run ME 2009 using the Luit and Abduco terminal utilities.
Luit as a wrapper application translates Unicode and ISO characters between the Terminal emulator and MicroEmacs and Abduco allows you to suspend both applications together. Instead of Abduco other supend tools like Dtach could be used. Here a simple wrapper script which allows allows all Western ISO-8859-15 characters (like the Euro symbol) to be used inside MicroEmacs:
#!/bin/sh
### file: mecu
### Description: wrapper to run MicroEmacs with extended character settings
### on UTF-8 enabled terminals
###
### Tools required:
### abduco: session management and detacher
### https://www.brain-dump.org/projects/abduco/
### luit: filter between non-utf-8 applications and utf-8 terminals
### https://invisible-island.net/luit/
### Installation:
### fedora: sudo dnf install abduco luit
### debian: sudo apt install abduco luit
### session name creation for the current tty
tty=$(tty | grep -Eo '[0-9]+')
## already running? list abduco sessions
res=$(abduco -l | grep mecb$tty)
### running session, if no create an new one
### otherwise attach to the old one
### (press in ME Ctrl-l to update screen if neccesary)
if [[ "$res" == "" ]] ; then
### need a new one
TERM=xterm abduco -A -e ^z mecb$tty luit -encoding ISO-8859-15 mecb "$@"
else
### attach to the old one
abduco -a -e ^z mec$tty
fi
Change the filename mecb to the name you give you MicroEmacs terminal
instance. Name the bash script above mec, Make it executable and move to a
folder belonging to your PATH variable. With this little shell script using
two small tools, you can run MicroEmacs nicely as well on all UTF-8 terminals
with a more extended character set. Obviously you can as well change the
encoding. Here is a list of all ISO encodings with a short description of
their usable letters - https://en.wikipedia.org/wiki/ISO/IEC_8859.
Pros and Cons of Jasspa MicroEmacs
- Pro:
- simple single file install
- small and fast 1-4 MB!! memory footprint
- support for Linux, MacOS and Windows
- almost same usage in terminal and GUI mode
- menu access to use command File, Edit etc commands A-f, A-e in GUI mode or "esc =" in terminal mode
- internal interactive help system
- distraction free coding, no popups, no annoying updates - just you and the editor
- Emacs like shortcuts
- CUA windows key-bindings as fallback for total newbees
- standard menu entries on top for beginners who do not yet know all the key bindings of Emacs
- easy to extend, the file USER.emf is your friend
- different color themes can be used and changed easily
- sophisticated macro programming language
- easy to configure file templates and snippets
- Cons:
- No unicode! It is a MICRO-Emacs!
- No softwrap! Use
Esc qfor paragraph wrapping! Or use the wrap buffer mode

Build
I currently build on Fedora ad Ubuntu using the file src/linux32gcc.gmk. Other Makefiles you should take from https://github.com/ipstone/microemacs/tree/master/src
To build switch into the src directory and then run the Makefile for your plaform. On my Linux machine I did:
cd src && make -f linux32gcc.gmk
Which then produces in the folder .linux32gcc-release-mecw the required executable.
I as well cross compile on my Linux systems for Windows. You can do the same assuming that you have installed on your Linux system the mingw32 gcc compiler and the required tools. The you can do this:
cd src && make -f linuxmingwgcc.mak CC=i686-w64-mingw32-gcc RC=i686-w64-mingw32-windres
cd src && make -f linuxmingwgcc.mak CC=i686-w64-mingw32-gcc RC=i686-w64-mingw32-windres BTYP=c
Which then produces in the folder .win32mingw-release-mew and -mec the required executables.
If you place the file zlib1.dll and eventuall the file dssp-0.dll in the same folder as the executable that file should be run using wine directly on a Linux system. To check the executable on Linux using wine you do something like this:
MEPATH=Z:/home/username/workspace/microemacs/jasspa/macros wine ~/path/to/mew32.exe
You can as well create an alias to shorten the command line.
Terminal issues
Menu access
The menu access is usually available using the F1 key, but sometimes this does not work as it is already bound by the terminal to some other function. As an alternative you can use the key binding "Esc =" to access the main menu on top.
Backspace key
The backspace key for some terminals is not mapped to delete the last
caracter, you might use instead C-h to delete the last character.
Color issues
As the capabilities of Terminals differ widely MicroEmacs starts usually in
black/white mode in the terminal. You can set this to color mode by selecting the
"Tools -> User Setup -> Platform" Termcap option. If this does not work you might
in addition declare the terminal type before starting me like so:
TERM=xterm me -n or TERM=rxvt me -n given the me
is you executable that could be as well defined as an alias in your .bashrc
file for instance like this:
### .bashrc
alias mec="TERM=xterm me -n"
### or alias mec="TERM=rxvt me -n"
You should check which of the two aliases works best with your terminal emulator (lxterminal, gnome-terminal, etc) and screen mulitplexer (tmux, gnu-screen, etc).
