.. _description:

Code audit tool for Python and JavaScript. Pylama wraps these tools:

* PEP8_ © 2012-2013, Florent Xicluna;
* PEP257_ © 2012, GreenSteam, <http://greensteam.dk/>
* PyFlakes_ © 2005-2013, Kevin Watters;
* Mccabe_ © Ned Batchelder;
* Pylint_ © 2013, Logilab (should be installed 'pylama_pylint' module);
* gjslint_ © The Closure Linter Authors (should be installed 'pylama_gjslint' module);

| `Pylint doesnt supported in python3.`

.. _requirements:

Requirements:
=============

- Python (2.6, 2.7, 3.2, 3.3)
- 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:

Instalation:
============
**Pylama** should be installed using pip: ::
::

$ pip install pylama


.. _quickstart:

Quickstart
==========

**Pylama** is easy to use and realy fun for checking code quality.
Just run `pylama` and get common output from all pylama plugins (PEP8_, PyFlakes_ and etc)

Recursive check the current directory. ::

$ pylama

Recursive check a path. ::

$ pylama <path_to_directory_or_file>

Ignore some errors ::

$ pylama -i W,E501

Customize linters ::

$ pylama -l "pep8,mccabe"

Customize linters for JavaScript::

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

.. _options:

Command line options
====================
::

$ pylama --help

usage: main.py [-h] [--verbose] [--format {pep8,pylint}] [--select SELECT]
[--linters LINTERS] [--ignore IGNORE] [--skip SKIP]
[--complexity COMPLEXITY] [--report REPORT] [--hook]
[--options OPTIONS]
[path]

Code audit tool for python.

positional arguments:
path Path on file or directory.

optional arguments:
-h, --help show this help message and exit
--verbose, -v Verbose mode.
--version show program's version number and exit
--format {pep8,pylint}, -f {pep8,pylint}
Error format.
--select SELECT, -s SELECT
Select errors and warnings. (comma-separated)
--linters LINTERS, -l LINTERS
Select linters. (comma-separated). Choices are
pep8,pep257,mccabe,pyflakes,pylint,gjslint.
--ignore IGNORE, -i IGNORE
Ignore errors and warnings. (comma-separated)
--skip SKIP Skip files by masks (comma-separated, Ex.
*/messages.py*)
--complexity COMPLEXITY, -c COMPLEXITY
Set mccabe complexity.
--report REPORT, -r REPORT
Filename for report.
--hook Install Git (Mercurial) hook.
--options OPTIONS, -o OPTIONS
Select configuration file. By default is
'<CURDIR>/pylama.ini'


.. _modeline:

File modeline
=============

You can set :ref:`options` for **Pylama** inside a source files.

::

.. Somethere in code
# lint_ignore=W:lint_select=W301


Disable code checking for current file: ::

.. Somethere in code
# lint=0


.. _skiplines:

Skip lines
==========

Just add `# noqa` in end of line for ignore. ::

.. Somethere in code
x=d+34 # noqa


.. _config:

Configuration file
==================

When starting **Pylama** try loading configuration file. By default: `<CURDIR>/pylama.ini`,
but you set it with "-o" option.

Section `main` contains a global options (see :ref:`options`), like `linters` and `skip`.

Other sections could set :ref:`modeline` for a custom files by filepath mask.

Example: `pylama.ini` ::

[main]
format = pylint
skip = */.tox/*,*/.env/*
linters = pylint,mccabe

[*/pylama/main.py]
lint_ignore = C901,R0914,W0212
lint_select = R

[*/tests.py]
lint_ignore = C0110

[*/setup.py]
lint = 0

Writing a linter
================

You can write a custom extension for Pylama.
Custom linter should be a python module. Name should be starts from 'pylama_'.

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

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

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

'allow' take a path and returned true if linter could check this file for errors.
'run' take a path and meta keywords params and return list of errors.

Example:
--------

Just 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'
}]
