Plugins

For performance and security reasons, we cannot embed every linter in MegaLinter.

But our core architecture allows building and publishing MegaLinter plugins!

Note: Using an external plugin means you trust its author.

Use external plugins

Add plugin URLs in the PLUGINS property of .mega-linter.yml. URLs must either begin with "https://" or take the form of "file://\<path>", where \<path> points to a valid plugin descriptor file.

Note: Both \<path> and the default mount directory (/tmp/lint/\<path>) will be checked for a valid descriptor.

Example

PLUGINS:
  - https://raw.githubusercontent.com/kpj/jupyfmt/master/mega-linter-plugin-jupyfmt/jupyfmt.megalinter-descriptor.yml
  - file://.automation/test/mega-linter-plugin-test/test.megalinter-descriptor.yml

Create your own plugin

You can implement your own descriptors and load them as plugins during MegaLinter runtime.

Descriptor format is exactly the same as MegaLinter embedded ones (see JSON schema documentation)
Plugin descriptor files must be named **.megalinter-descriptor.yml and conform to the MegaLinter JSON Schema
Plugins must be hosted in a URL containing **/mega-linter-plugin-**/
File URLs must conform to the same directory and file naming criteria as defined above.

Limitations

For now, the only install attributes managed are dockerfile instructions starting by RUN

Community Tools

Beyond plugins, the community has built additional tools that integrate with MegaLinter. These are independently maintained and not affiliated with the MegaLinter team.
