Unless you are a vim or emacs aficionado you should probably prefer atom.
For linux ignore any distro version and download latest version:-
sudo dpkg --install atom-amd64.deb # debian, mint, ubuntu sudo pacman -S atom # Archlinux currently installs 1.26.1
MacOS/Windows users could just download direct (or homebrew on MacOS)
Tough luck if you want the 32 bit version on debian linux
From the atom editor install the
atom-k9 package by Martin Prout (monkstone)
While you are at install the
language-jruby-art package also by Martin Prout for code snippets (includes a
bare JRubyArt sketch)
set-syntax package by Lee Dohm to allow easy setting of buffer syntax
Watching Sketches (a pseudo REPL)
To watch sketches you should create a new folder (to avoid watching too many files) and to reliably pick up the local environment (eg path to
k9) you should start atom from a terminal (gnome-terminal linux, mintty cygwin).
mkdir watch # create a new folder cd watch # navigate to folder touch my_sketch.rb # create an empty file atom my_sketch.rb # fire up atom from command line (to pick up local environment)
Make sure you are in
JRuby Art edit mode (click on bottom right hand corner to choose).
Or if you’ve installed
set-syntax load command palette with
ctrl-shift-p and enter
ssjru to choose.
bare snippet to create sketch, NB: below gif has not been updated to show red
JRA label that helpfully highlights core JRubyArt snippets
ctrl-s to save.
For a pseudo
REPL select watch from menu or
ctrl+shift+alt+w. Then the sketch will reload on
ctrl-s after edit.
If you want to avoid need to start from a terminal, create a symbolic link to a regular system path to
k9 (eg /usr/local/bin/k9), this easily done/managed on debian linux (with
To run a sketch
To simply run a sketch, navigate to the sketch (file) and use either JRubyArt menu, or
To close a running sketch
Close the console from the JRubyArt menu (or just close the sketch window)
What’s it look like
Expanding / Modifying snippets
Navigate to ~/.atom/packages/language-jruby-art/snippets and edit
Linter Ruby Leek package etc
Fans of Sandi Metz will may want to experiment with the linter-ruby-reek and rubocop packages, the latter v. useful for detecting stupid coding errors.
