• Independent webOS package repository

  • Homebrew discovery, installation & updates

• (root) Root execution service that can be easily used by webOS homebrew developers without a need of separate privilege escalation handling (luna://org.webosbrew.hbchannel.service/exec)

• (root) Disable some telemetry

• (root) Startup user hooks (executable scripts present in /var/lib/webosbrew/init.d are run on bootup)

• (root) Remote access

  • SSH - public key authenticated (with default alpine password until authorized keys are provisioned)
  • Telnet - unauthenticated, use sparingly

• (root) Failsafe mode

  • In case a device crashes on boot only an emergency shell will be exposed via telnet. In order to disable it fix the original crash cause and remove /var/luna/preferences/webosbrew_failsafe flag file.

Execute the following snippet on target TV using SSH or Telnet:

curl -L https://raw.githubusercontent.com/webosbrew/webos-homebrew-channel/main/tools/install.sh | sh -

# Update startup script
cp /media/developer/apps/usr/palm/services/org.webosbrew.hbchannel.service/startup.sh /media/cryptofs/apps/usr/palm/services/com.palmdts.devmode.service/start-devmode.sh

• Download latest release .ipk
• Install it using ares-install SDK command or using the following command directly on a TV:

  luna-send-pub -i 'luna://com.webos.appInstallService/dev/install' '{"id":"com.ares.defaultName","ipkUrl":"/tmp/path/to/hbchannel.ipk","subscribe":true}'`

• (root) Elevate privileges by running:

  /media/developer/apps/usr/palm/services/org.webosbrew.hbchannel.service/elevate-service

• (root) Update startup script:

  cp /media/developer/apps/usr/palm/services/org.webosbrew.hbchannel.service/startup.sh /media/cryptofs/apps/usr/palm/services/com.palmdts.devmode.service/start-devmode.sh

Some libraries used by this project are submodules of this repository. Use following command when cloning:

git clone --recursive https://github.com/webosbrew/webos-homebrew-channel

All required development packages are distributed via npm. In order to install them in a local directory run:

npm install

Frontend is based on last development version of enyo. (dated january 2017) While this definitely is not the cool and jazzy latest technology, it provides us with a sensible UI toolkit for TV-based application that seems to work pretty well with versions of webOS as old as 1.x. We are currently using enyo built-in enyo-dev packager. This requires us to write code that'll be run directly on target platforms (no babel/transpilation of newer ES dialects - no arrow functions, no const, no promises, etc.). In the future we may migrate to some webpack-based solution around that.

Service is packaged using webpack & babel, thus, with enough shims and patches, we can write and use some modern ES features (like Promises, arrow functions, async functions, const, etc.) while targeting NodeJS 0.10 (used on earliest webOS versions)
