Commands

Everything goes through /gob. /goblinomics does the same if you have another addon that already claimed /gob. Anything the addon doesn't recognise prints the list of commands.

Command	What it does
/gob	Opens or closes the main window
/gob help	Lists the commands in chat
/gob setup	Opens the setup window (price sources and modules)
/gob import	Opens the settings, where you'll find the Import section
/gob status	Prints the version and which modules are loaded, and in what state
/gob perf	Prints a performance report
/gob perf reset	Resets the performance counters
/gob price <item link>	Shows all prices Goblinomics knows for an item and how it would be valued
/gob jealous <gold>	Previews the Jealousmeter at that amount of gold, e.g. /gob jealous 2500000
/gob jealous off	Ends the preview
/gob farm start [farm name]	Starts a Gatherer session, for a farm if you give its name
/gob farm pause	Pauses the session, or resumes it if it's paused
/gob farm resume	Resumes the session
/gob farm stop	Stops the session and shows the summary
/gob farm hud	Shows or hides the session HUD
/gob farm instances	Diagnostic output for the instance list of dungeon and raid farms
/gob debug [on|off]	Prints core events (money, loot, items) to chat; without an argument it toggles

The jealous and farm commands belong to the Vault and Gatherer modules, so they're gone when those modules are switched off.

/gob price is the one I use most when a number looks off. Shift-click an item into the chat box after typing /gob price , and you get the market, destroy, sale rate and vendor values along with where each came from, then how the item counts as a tradable and as a bound item. If a value says "loading item data, try again", the game hadn't cached the item yet; run it once more.
