Linters

A linter is an analysis tool that checks for common errors or compatibility issues, usually automatically, or as part of some other process.

Snapcraft 7.2 and higher provides built-in linter functionality when the snap uses core22 or higher as its base.

By default, these built-in linters run automatically when a snap is built. If they’re unneeded, you can disable them in the snap’s project file.

Built-in linters

Snapcraft runs the following linters:

• classic. Verifies binary file parameters for snaps using classic confinement.

• library. Verifies that no ELF file dependencies, such as libraries, are missing, and that no extra libraries are included in the snap package.
