Green.Rules.Naming.AvoidOneLetterVariables (green v0.2.0)

This module prints a warning if there are one-letter variable names.

Configuration

This rule is enabled by default, but can be disabled globally in the configuration file.

The rule can also be configured to ignore specific files, or specific lines in specific files. This is useful for cases where applying the rule would be problematic.

In .formatter.exs:

  green: [
    avoid_one_letter_variables: [
      enabled: *true | false,
      except: [
        "path/to/file.exs",
        {"path/to/other_file.exs", 42},
        {"path/to/yet_another_file.exs", [10, 20, 30]}
      ]
    ]
  ]
