- Add missing fix mode options for: CLANG_FORMAT, ENV,
GOOGLE_JAVA_FORMAT, NATURAL_LANGUAGE, PYTHON_ISORT, RUST_CLIPPY.
- Refactor linter tests to make them shorter because there's no need to
have big test files.
- Refactor 'bad' linter tests for linters that support fix mode so they
contain only automatically fixable issues. This is needed to avoid
adding another set of 'bad' linter tests for fix mode.
- Provide configuration files for linters that support fix mode and for
which the default configuration is not suitable to enable fix mode:
ansible-lint, ESLint, golangci-lint.
- Add a test case for linter commands options for linters that support
fix mode, to ensure that fix mode and check-only mode options have
been defined.
- Refactor the fix mode test to check if linters actually applied
modifications to files.
- Update documentation about adding test cases for linters that support
fix mode.
- Don't exit with a fatal error if VALIDATE_xxx is false when testing
fix mode because not all linters support fix mode. To enable this, set
the new FIX_MODE_TEST_CASE_RUN variable to true.
Certain linters and formatters support fixing linting and formatting
issues (fix mode). Before this change, Super-linter runs linters and
formatters in a mode that doesn't modify the source code in any way
(check only mode).
With this change, Super-linter supports running linters and formatters
in fix mode if explicitly requested by the configuration. If the
configuration includes a variable named FIX_<language_name>,
Super-linters modifies the command to run the linter or formatter for
<language_name> to enable fix mode.
The modifications to the linter or formatter command that Super-linter
applies depend on what is the default for a particular linter: it either
removes or adds options to the command to run the linter or formatter.
