2021.1.1 update: Fixed an issue with the Hotkey used to execute statement at cursor in IntelliShell, and various other bug fixes, see change log

We’re starting the New Year with the fastest IntelliShell version to date. Query faster, get auto-suggestions quicker, and enjoy a better shell-like experience all around.

IntelliShell | A better, faster mongo shell

We’ve rebuilt IntelliShell to be faster and feel more like a terminal shell. Now you can run queries and get auto-suggestions faster than in the old IntelliShell, and enjoy perks like live error highlighting and the ability to pin only the query results you want to keep.

New button, same functionality

IntelliShell users will notice a new button in the toolbar: Enable Query Assist. It’s always been running in the background in the old IntelliShell, we’ve just given it a name this time around.

Think of it as non-Raw Shell Mode. With Query Assist enabled, eligible find and aggregation queries are run via Studio 3T instead of the mongo shell, generating results in a separate, powerful result tab per query. Results for find queries even support editing in place.

Query Assist and separate tabs

Enabling Query Assist also means that you can use Query Code to generate code from your queries, and Visual Explain to help optimize query performance.

What about Raw Shell Mode?

The toolbar icon might be gone, but Raw Shell Mode remains. Disable Query Assist and that’s what you get.

You can run multiple find and aggregation queries and scripts at once, but their results will appear along with other shell commands and scripts in the Raw Shell Output tab.

Raw Shell Output tab

As one would expect in a real terminal or shell, you won’t be able to edit or page through the results. Query Code and Visual Explain will also not be available for these queries.

Intuitive error highlighting

Mistakes – we all make them. In this version, we’ve made it easier to spot them by highlighting them as you type.

IntelliShell error highlighting

We’ve also noted them in the left-hand sidebar and right-hand overview ruler as red markers you can hover over or click on for more information.

Pin query results in multiple tabs

According to your feedback, the old “Retain" option in the old IntelliShell led to tab clutter – and we totally get it.

Tab clutter

We’ve replaced this option with “Pin Query Result", so now you can choose the query results you want to keep.

Pin query results

We’ve also made it easier to tell which tab is which, by adding the query’s corresponding line number in the tab name.
