How to Install Light Table IDE in Ubuntu 16.04 via PPA

Last updated: May 23, 2016

This is a quick tutorial shows how to easily install the Light Table IDE in 64-bit Ubuntu via PPA, since there’s no official .deb binary for Ubuntu Linux.

Light Table is a cross-platform and open-source IDE that features real-time feedback allowing instant execution, debugging and access to documentation.

To make it easy to install Light Table IDE in Ubuntu, there’s now a PPA that contains an installer script, which automatically downloads the official Linux package from its website, installs and creates a launcher shortcut in your system for better Ubuntu integration.

1. First download the script from the link below:

Light Table Installer (.deb)

Select download the package “lighttable-installer_xxx_amd64.deb”, the click install via Ubuntu Software.

Or open terminal (Ctrl+Alt+T) and run command install the downloaded package. The script starts automatically after installation:

sudo dpkg -i ~/Downloads/lighttable-installer_*.deb

If everything goes OK, you’ll be finally able to launch the IDE from Unity Dash, or other Application Launcher.

2. (Optional) To receive future updates of Light Table along with other system udpates, you may add the PPA repository so to get updates via Software Updater once a new release is made into PPA.

sudo add-apt-repository ppa:dr-akulavich/lighttable

You can then disable, remove, or edit the PPA via System Settings -> System -> Software & Updates -> Other Software.

Light Table 0.7.1 Released, How to Install it in Ubuntu 14.10

Last updated: November 20, 2014

The Light Table IDE got a fairly major update a few hours ago by releasing the Light Table 0.7.0. And the 0.7.1 release was out just one hour later with few bug fixes.

Light Table 0.7.0 is a big clean up release with lots of little fixes, but there are a number of big changes that warranted it being a more significant version increase:

moved to the latest node-webkit and are now able to track nw’s progress directly since the menu changes made it upstream.
All plugin metadata is now hosted on github, this means that asking to remove/rename/change urls etc for plugins is just a matter of sending a PR.
Instead of having a disconnect between settings and plugins (which are really the same), every user now has a user plugin. This gives you a place to quickly create commands, tabs, behaviors, or whathaveyou without needing to jump through a bunch of hoops. This also means that your complete configuration with plugins and all can be zipped up and sent to someone.
Along with the user plugin, we’ve also changed the syntax of behavior and keymap files to make them much easier to both read and share. No more hunting for the right place to paste some behavior you’ve copied from someone else.
