Acme text editor

Acme is a Zen-style text editor.

Using Acme you sacrifice:

configuration files
themes
syntax highlighting
autocompletion
specific language support
your favourite Vim/Emacs/Sublime feature

What you gain is that instead of spending too much time configuring your editor, you will focus on actual working.

The killer feature of Acme is how it integrates into surrounding system. Acme is not trying to be a complete environment by itself. Acme acts as a glue which links together other programs and tools. With Acme the OS becomes your IDE.

Install

macOS

mkdir $HOME/9 && cd $HOME/9
git clone https://github.com/9fans/plan9port/ && cd plan9port
./INSTALL

./INSTALL -r $HOME/plan9

Environment setup

export PLAN9="/path/to/plan9port"

Font

Run font server:

fontsrv

In case it's not installed:

cd /path/to/plan9port/src/cmd/fontsrv/
9 mk install

Have a look at all available fonts:

9p ls font

Try one of them:

acme -f /mnt/font/'Droid Sans Mono'/13a/font

Run

I spawn Acme by running a script.

Scripts

Who is who in bin directory:

a start Acme
b create an indented C-like block { ... }
c SYMBOL/uc SYMBOL comment/uncomment selection
commit MESSAGE commit and push to master
css and cssify transform abbreviations into CSS properties
f TEXT find TEXT using The Silver Searcher
