FirefoxOS Simulator
This one is a bit hacky right now, and object inspection doesn't work yet, but feel free to try. The .tabs
command lists the currently open apps in the simulator.
- Install FirefoxOS Simulator in Firefox
- Start the Simulator with Tools > Web Developer > Firefox OS Simulator
- Get the port the Simulator is listening on with this terminal command:
lsof -i -P | grep -i "b2g"
in Linux/Mac. - Start
fxconsole
and with the --port
argument.
Usage
fxconsole --port 6000 --host 10.251.34.157
Commands
There are two extra REPL commands available beyond the standard node.js commands. .tabs
lists the open tabs in Firefox. .switch 2
switches to evaluating in a tab. The argument is the index of the tab to switch to.
