mypy-runner 0.1.3

Run mypy with options to filter errors and colorize output

Features

Adds the following features to mypy:

• Display colorized output

• Convert errors to warnings

• Filter errors and warnings

Options

usage: mypyrun [-h] [--list] [--daemon] [--select SELECT] [--ignore IGNORE]
               [--warn WARN] [--no-color] [--show-ignored] [--show-error-keys]
               [--options OPTIONS]
               [files [files ...]]

positional arguments:
  files                 Files to isolate (triggers use of 'active'options for
                        these files)

optional arguments:
  -h, --help            show this help message and exit
  --list                list error codes
  --daemon, -d          run in daemon mode (dmypy run)
  --select SELECT, -s SELECT
                        Errors to check (comma separated)
  --ignore IGNORE, -i IGNORE
                        Errors to skip (comma separated)
  --warn WARN, -w WARN  Errors to convert into warnings (comma separated)
  --no-color            do not colorize output
  --show-ignored, -x    Show errors that have been ignored (darker if using
                        color)
  --show-error-keys     Show error key for each line
  --options OPTIONS, -o OPTIONS
                        Override the default options to use the
                        namedconfiguration section (e.g. pass --options=foo to
                        use the [mypyrun-foo] section)

As with tools like flake8, you use specific error codes to enable or disable error output. Errors that are ignored or converted into warnings will not trigger a non-zero exit status. To see the list of error codes and their regex pattern, run mypyrun --list.

Configuration

mypyrun looks for a [mypyrun] section in either mypy.ini or mypyrun.ini.

Here’s an example configuration file:

[mypyrun]

# run dmypy instead of mypy
daemon = true

# only display these errors
select =
    not_defined,
    return_expected,
    return_not_expected,
    incompatible_subclass_attr,

# all other errors are warnings
warn = *

# filter errors generated from these paths:
exclude =
    thirdparty/*,

# pass these paths to mypy
paths =
    arnold/python,
    houdini/python,
    katana/python,
    mari/python,
    maya/python,
    nuke/python,
    python/packages,
