mops lint

Lint Motoko source files using lintoko

mops lint [filter]

Runs lintoko on all .mo files in the project. If a filter is provided, only files matching **/*<filter>*.mo are linted.

Rules are loaded from a lint/ or lints/ directory in the project root (if present), or can be specified with --rules.

Options​

--fix​

Automatically apply lint fixes.

--verbose​

Show the full lintoko invocation before running it and pass --verbose to lintoko.

--rules, -r​

Specify one or more directories containing lint rules. Can be used multiple times. Defaults to lint/ or lints/ if they exist.

mops lint --rules ./rules-a --rules ./rules-b

Configuration​

Extra lintoko flags can be set in mops.toml:

args = ["--severity", "warning"]

Exits with a non-zero code if any lint errors are found.
