Snakefmt extension for Visual Studio Code

A Visual Studio Code extension that formats Snakemake code using Snakefmt. The extension ships with snakefmt=0.10.2. The bundled snakefmt is used if no path to the executable or interpreter is specified.

Features

This extensions uses snakefmt to format your Snakemake code. It can also supports formatting Python code. It automatically checks if your Snakemake file is formatted according to snakefmt. You can disable this feature by setting snakefmt.disableLinting = true. This feature is disabled per default for Python files and can be enabled with snakefmt.enablePythonLinting = true.

Files or code chunks can be formatted on-demand by right clicking in the document and selecting "Format Document", or by using the associated keyboard shortcut (usually Ctrl+⇧+F on Windows, Ctrl+⇧+I on Linux, and ⇧+⌥+F on macOS).

To automatically format a file on save, add the following to your vscode settings.json file:

{
    "editor.formatOnSave": true
}
