.. _requirements:

Requirements:

Python (2.7, 3.4, 3.5, 3.6, 3.7)
To use JavaScript checker (gjslint) you need to install python-gflags with pip install python-gflags.
If your tests are failing on Win platform you are missing: curses - http://www.lfd.uci.edu/~gohlke/pythonlibs/
(The curses library supplies a terminal-independent screen-painting and keyboard-handling facility for text-based terminals)

.. _installation:

Installation:

Pylama could be installed using pip: ::
::

$ pip install pylama

.. _quickstart:

Quickstart

Pylama is easy to use and really fun for checking code quality.
Just run pylama and get common output from all pylama plugins (pycodestyle_, PyFlakes_ and etc)

Recursive check the current directory. ::

$ pylama

Recursive check a path. ::

$ pylama <path_to_directory_or_file>

Ignore errors ::

$ pylama -i W,E501

.. note:: You could choose a group erros D,E1 and etc or special errors C0312

Choose code checkers ::

$ pylama -l "pycodestyle,mccabe"

Choose code checkers for JavaScript::

$ pylama --linters=gjslint --ignore=E:0010 <path_to_directory_or_file>

.. _options:

Set Pylama (checkers) options

Command line options

$ pylama --help

usage: pylama [-h] [--verbose] [--version]
              [--format {pep8,pycodestyle,pylint,parsable}] [--select SELECT]
              [--sort SORT] [--linters LINTERS] [--ignore IGNORE]
              [--skip SKIP] [--report REPORT] [--hook] [--concurrent]
              [--options FILE] [--force] [--abspath]
              [paths [paths ...]]

Code audit tool for python.

positional arguments:
  paths                 Paths to files or directories for code check.

optional arguments:
  -h, --help            show this help message and exit
  --verbose, -v         Verbose mode.
  --version             show program's version number and exit
  --format {pep8,pycodestyle,pylint,parsable}, -f {pep8,pycodestyle,pylint,parsable}
                        Choose errors format (pycodestyle, pylint, parsable).
  --select SELECT, -s SELECT
                        Select errors and warnings. (comma-separated list)
  --sort SORT           Sort result by error types. Ex. E,W,D
  --linters LINTERS, -l LINTERS
                        Select linters. (comma-separated). Choices are mccabe,
                        pep257,pydocstyle,pep8,pycodestyle,pyflakes,pylint,iso
                        rt.

  --hook                Install Git (Mercurial) hook.
  --concurrent, --async
                        Enable async mode. Useful for checking a lot of files.
                        Unsupported with pylint.
  --options FILE, -o FILE
                        Specify configuration file. Looks for pylama.ini,
                        setup.cfg, tox.ini, or pytest.ini in the current
                        directory (default: None).
  --force, -F           Force code checking (if linter doesn't allow)
  --abspath, -a         Use absolute paths in output.

.. _modeline:

File modelines

You can set options for Pylama inside a source file. Use
pylama modeline for this.

Format: ::

# pylama:{name1}={value1}:{name2}={value2}:...

 .. Somethere in code
 # pylama:ignore=W:select=W301

Disable code checking for current file: ::

 .. Somethere in code
 # pylama:skip=1

Those options have a higher priority.

.. _skiplines:

Skip lines (noqa)

Just add # noqa in end of line to ignore.

def urgent_fuction():
    unused_var = 'No errors here' # noqa

.. _config:

Configuration file

Pylama looks for a configuration file in the current directory.

The program searches for the first matching ini-style configuration file in
the directories of command line argument. Pylama looks for the configuration
in this order: ::

pylama.ini
setup.cfg
tox.ini
pytest.ini

The "--option" / "-o" argument can be used to specify a configuration file.

Pylama searches for sections whose names start with pylama.

The "pylama" section configures global options like linters and skip.

[pylama]
format = pylint
skip = */.tox/*,*/.env/*
linters = pylint,mccabe
ignore = F0401,C0111,E731

Set Code-checkers' options

You could set options for special code checker with pylama configurations.

[pylama:pyflakes]
builtins = _

[pylama:pycodestyle]
max_line_length = 100

[pylama:pylint]
max_line_length = 100
disable = R

See code-checkers' documentation for more info. Let's notice that dashes are
replaced by underscores (e.g. Pylint's "max-line-length" becomes
"max_line_length").

Set options for file (group of files)

You could set options for special file (group of files)
with sections:

The options have a higher priority than in the pylama section.

[pylama:*/pylama/main.py]
ignore = C901,R0914,W0212
select = R

[pylama:*/tests.py]
ignore = C0110

[pylama:*/setup.py]
skip = 1

Pytest integration

Pylama has Pytest_ support. The package automatically registers itself as a pytest
plugin during installation. Pylama also supports pytest_cache plugin.

Check files with pylama ::

pytest --pylama ...

Recommended way to set pylama options when using pytest — configuration
files (see below).

Writing a linter

You can write a custom extension for Pylama.
Custom linter should be a python module. Name should be like 'pylama_<name>'.

In 'setup.py', 'pylama.linter' entry point should be defined. ::

setup(
    # ...
    entry_points={
        'pylama.linter': ['lintername = pylama_lintername.main:Linter'],
    }
    # ...
)

'Linter' should be instance of 'pylama.lint.Linter' class.
Must implement two methods:

'allow' takes a path and returns true if linter can check this file for errors.
'run' takes a path and meta keywords params and returns a list of errors.

Example:

Just a virtual 'WOW' checker.

setup.py: ::

setup(
    name='pylama_wow',
    install_requires=[ 'setuptools' ],
    entry_points={
        'pylama.linter': ['wow = pylama_wow.main:Linter'],
    }
    # ...
)

pylama_wow.py: ::

from pylama.lint import Linter as BaseLinter

class Linter(BaseLinter):

    def allow(self, path):
        return 'wow' in path

    def run(self, path, **meta):
        with open(path) as f:
            if 'wow' in f.read():
                return [{
                    lnum: 0,
                    col: 0,
                    text: 'Wow has been finded.',
                    type: 'WOW'
                }]

Run pylama from python code

from pylama.main import check_path, parse_options

# Use and/or modify 0 or more of the options defined as keys in the variable my_redefined_options below.
# To use defaults for any option, remove that key completely.
my_redefined_options = {
    'linters': ['pep257', 'pydocstyle', 'pycodestyle', 'pyflakes' ...],
    'ignore': ['D203', 'D213', 'D406', 'D407', 'D413' ...],
    'select': ['R1705' ...],
    'sort': 'F,E,W,C,D,...',
    'skip': '*__init__.py,*/test/*.py,...',
    'async': True,
    'force': True
    ...
}
# relative path of the directory in which pylama should check
my_path = '...'

options = parse_options([my_path], **my_redefined_options)
errors = check_path(options, rootdir='.')
