Visual Studio Code extension for Jsonnet
A simple bare-bones extension providing simple syntax highlighting for Jsonnet files (specifically, files with the
.libsonnet suffixes), as well as a Markdown-style preview pane that auto-updates every time you save.
Syntax highlighting works out of the box. Just open any
.libsonnet file, and it will magically work.
To enable the Jsonnet preview pane, it is necessary to install the Jsonnet command line tool (e.g., through
brew install jsonnet). If you don’t add the
jsonnet executable to the
PATH then you will need to customize
jsonnet.executablePath in your
settings.json, so that the extension knows where to find it.
After this, you can use the keybinding for
jsonnet.previewToSide (by default this is
shift+cmd+i on macOS), and the preview pane will open as in the picture above.
This extension exposes the following settings, which can be cusomized in
jsonnet.executablePath: Tells the extension where to find the
jsonnetexecutable, if it’s not on the
PATH. (NOTE: This setting is always necessary on Windows.)
This extension exposes the following commands, which can be bound to keys:
jsonnet.previewToSide: Compiles the Jsonnet file to JSON, places result in a “preview” window in the pane to the right of the active pane, or in the current pane if active window is pane 3 (since vscode only allows 3 panes). Default: bound to
jsonnet.previewToSide: Compiles the Jsonnet file to JSON, places result in a “preview” window in the current active pane. Default: no keybinding.
jsonnet.extStrs: An object of variable, value pairs. Allows you to customize the external variables passed to the
jsonnetcommand line. It can be particularly useful to set this in a workspace configuration, so that you can set different variables on a per-project basis.
jsonnet.outputFormat: A choice of two string literals:
["json", "yaml"]. This tells the extension what format you’d like the output to be (i.e., allows you to either output JSON or YAML).
