irb (interactive ruby) for Opal (Ruby running on javascript). This is interactive console (REPL) on a webpage. Good for testing Opal/ruby interactively without having to install anything. Intended to be part of a browser based interactive development tool for Opal

- Opal irb in your browser
- Command history - up/down arrows, ctrl-n/ctrl-p
- Multiline support - ctrl-m to enter editor, ctrl-Enter to submit code
- Colorized output
- Access last returned value via $_
- Shareable code links like this
- create links by hitting ctrl-L and the lines/multilines will be made into a shareable link
- also can create links using the history number, i.e. irb_link_for 2
- Emacs keystrokes like all GNU readline apps (original irb included)
- 100% HTML and JavaScript
Embedding into lissio app, as made by lissio new
- add to Gemfile opal-irb
# gem 'opal-irb', '0.7.0' for Opal 0.7.*
# gem 'opal-irb', '0.8.*' for Opal 0.8.*
# For latest do below
gem 'opal-irb', github: 'fkchang/opal-irb'- invoke app to require opal-jquery and opal-irb
lissio start --require opal-irb- add a helper which includes the jquery and codemirror requirements
<%= OpalIrbUtils.include_opal_irb_jqconsole_requirements %>- change the require in app/app.rb -- order matters, at the moment to have opal-jquery and opal-browser coexist you need to load opal-jquery before loading lissio
require 'opal'
require 'jqconsole' # add these 3 jqconsole support
require 'opal_irb_jqconsole_css' # css for opal_irb_jqconsole_css
require 'opal_irb_jqconsole' # the console code
require 'lissio'- override Application#start() to create a button and hook up opal-irb
def start
super
element << DOM do
button.show_irb! "Show Irb"
end
OpalIrbJqconsole.create_bottom_panel
OpalIrbJqconsole.add_open_panel_behavior("show_irb")
end- profit!
- setup Rails app for opal use via https://github.com/opal/opal-rails
- add to Gemfile opal-irb, jquery-ui-rails (for multi editor)
# gem 'opal-irb', '0.7.0' for Opal 0.7.*
# gem 'opal-irb', '0.8.*' for Opal 0.8.*
# For latest do below
gem 'opal-irb', github: 'fkchang/opal-irb', require: 'opal-irb-rails'
gem 'jquery-ui-rails'- include stylesheets in application.css.scss
/*= require_self
*= require jquery-ui/dialog
*= require opal-irb/jqconsole
*/- include jquery UI dialog in application.js
- for Opal 0.7.0 if you have kept application.js vs converting to application.js.rb
//= require jquery-ui/dialog- for Opal 0.8.0, you must create application.js.rb or else you are forced to load the opal modules by hand
require 'jquery-ui/dialog'- include codemirror js/css, you can pull from CDN w/the below in your template (haml example below)
= OpalIrbUtils.include_code_mirror.html_safe-
Set it up in opal code
- Example that creates a bottom panel, a button to bring it up
require 'opal_irb_jqconsole'
# opal-browser code to add a button
$document["#workarea"] << DOM do
button.show_irb! "Show Irb"
end
# opal-jquery code to add a button
Element.find(".main").append "<button class='btn' id='show_irb'>Show Irb</button>"
# creates a panel at the bottom
OpalIrbJqconsole.create_bottom_panel(hidden=true)
# adds open panel behavior to element w/id show_irb
OpalIrbJqconsole.add_open_panel_behavior("show_irb")- Example that creates a bottom panel, makes a hot key "shift-command-c" to toggle the panel
OpalIrbJqconsole.create_bottom_panel(hidden=true)
OpalIrbJqconsole.add_hot_key_panel_behavior(modifiers: %w(meta shift), key: "c")- profit!
- opal - of course
- opal-jquery (would like to do away with this, don't need it)
- jquery (cuz of the above)
- jquery-ui dialog - for the code dial
- code mirror - for code editing
- opal-browser (so you can use it from opal-irb) OPTIONAL, it's used in the examples but it can be deployed without opal-browser, esp. since Rails defaults to using jquery and opal-browser and opal-jquery have a lot of overlap, and some small conflicts
While in my mind there are a lot of things that keep opal-irb at not yet suitable to be a gem/ 0.1.0 version number, I frequently have to change code to support the latest minor release for Opal, so I think I need to adopt a scheme that tracks such. So the 1st gem release will be 0.7.0, to indicate compatibility with 0.7.* versions of opal, followed fairly quickly with a 0.8.0 release to match 0.8.0 the current version (at time of writing) of opal.
- Figure out how to keep variables -- DONE 6/10/2013, thx @adambeynon
- have it automatically know when a complete ruby expression is there instead of multi line mode like irb -- CLOSE ENOUGH 6/21/2013 via jqconsole
- Make a gem - DONE 6/23/2013 1st for use in opal-inspector, made into a bonafide gem 9/1/15
- Hook into smalltalk style object browser for opal that I plan to write - STARTED
- Some demos to show how convenient it can be - DONE 7/19/2013 - you tube video overview
- Add more irb/pry functionality
- tab completion - DONE
- cd ls
- show source via source maps and opal-inspector
- Make embeddable in any app STARTED 7/30/2013, made embeddable into lisso 2/4/2014
- print out inspect in ruby format
- Rails plugin - WORK done on 8/27/14, works w/opal rails and assets, need to document
- navigate stacktrace code via source maps
- remove jquery dependancy -- need to convert jqconsole, and remove the the jquery-ui dialog
- split up dependancy and hierarchy, jquery and jquery free versions, rails vs no rails, etc.
