Julia VS Code extension v0.16 release

Welcome to the v0.16 release of the Julia VS Code extension.

Inline evaluation

Code evaluation has been overhauled for this release.

The Julia: Execute * (e.g. Julia: Execute Code And Move, by default accessible with Alt-Enter) commands now asynchronously evaluate the selection, current code block, or file. These commands also evaluate the code in the context of their containing module, which is indicated in the status bar:

You can change the module for a file by clicking on the module indicator or by calling the Julia: Select Current Module command (e.g. with the Ctrl-J Ctrl-M keybinding).

Evaluating code directly into a module is especially helpful for a Revise-less workflow – it allows you to easily update methods or globals.

Another new feature in this release are inline results for code evaluated from the editor. To enable them, select the inline result type in the extension's Julia > Execution: Result Type setting.

Inline results display the first line of the result's plain-text representation (via Base.show). Details are available by hovering over the result, like in the screenshot below (make sure you have the Editor > Hover: Enabled setting ticked):

The inline result on the current line can be cleared with Julia: Clear Current Inline Result (Ctrl-I Ctrl-D); all inline results in the active text editor are cleared with Julia: Clear All Inline Results (Ctrl-I Ctrl-C).

We're still working on inline evaluation, inline results, and related features, so expect more changes in the following releases.


The Julia: Send Current Line or Selection to REPL command simply copies the current line or selection and pastes it into the REPL, so it does not take the code's module into account.

Workspace view

It's now possible to inspect the current REPL's runtime state in the Workspace pane, which you can open with the View: Show Julia Explorer command or by clicking on the Julia symbol in the activity bar.

You can drill down into modules and find out what they define, inspect complex structs or dictionaries, and even inspect arbitrarily large arrays:

All of this lazy-loaded, so don't worry about recursive types or big arrays – we're taking great care not to influence the editor's performance or mess with Julia's GC.

Supported types like arrays (or other table-like objects) and plots can be shown in the integrated table viewer or plot pane with the click of a button.

Faster REPL startup

All code the extension loads into the REPL process is now in a (precompiled) module, which should speed up startup.


We've also fixed a plethora of issues in the Language Server and the interactive code.
