Description:

pyloc 0.2.0

pyloc prints the location of the definition of any python object in
your file-system.

Introduction
pyloc is very similar to what python3 -m inspect -d <object>
offers. However, it is only focused to retrieve the file name (and
eventually the line number) where a given Python object is defined.
The object can be a package, module, class, method or function.
pyloc makes some further efforts to figure out the line and column
number and its output is formatted so that it can easily be passed
to emacsclient or vi.

Examples
You can see the location of Popen.wait method in the sub-process package:
$ python -m pyloc -f human subprocess:Popen.wait
Filename: /Users/polrop/.pyenv/versions/2.7.9/lib/python2.7/subprocess.py
Line: 1379

$ python -m pyloc -f human email.utils:formataddr
Filename: /Users/polrop/.pyenv/versions/2.7.9/lib/python2.7/email/utils.py
Line: 85
(Output may be different on your system if you have different
installation path and version)
Note that the object naming syntax is as follow: module[:qualname]
Since version 0.2.0, syntax module[.qualname] a la pydoc is also
supported.
To open it in Emacs you can do:
$ emacsclient `python -m pyloc -f emacs subprocess:Popen.wait`
or in vim:
$ vim `python -m pyloc -f vi subprocess:Popen.wait`
If you are lazy typing -f <format> all the time and you often use
the same format, you can set the default output format this way (you
can add this line in your .zshenv or .bashrc):
$ export PYLOC_DEFAULT_FORMAT=emacs
pyloc will always locate object based on the python interpreter
your are using:
$ python3 -m pyloc -f human subprocess:Popen.wait
Filename: /Users/polrop/.pyenv/versions/3.4.3/lib/python3.4/subprocess.py
Line: 1526

$ /usr/local/bin/python -m pyloc -f human email.utils:formataddr
Filename: /usr/local/Cellar/python/2.7.9/Frameworks/Python.framework/Versions/2.7/lib/python2.7/email/utils.py
Line: 85

$ /usr/bin/python -m pyloc -f human email.utils:formataddr
Filename: /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/email/utils.py
Line: 85

Installation

Using pip
You can install pyloc using pip like this:
$ pip install pyloc
or
$ pip3 install pyloc

Directly from the source
$ git clone https://github.com/nicolasdespres/pyloc.git
$ cd pyloc
$ python setup.py develop
# If you also want it for Python 3
$ python3 setup.py develop
Note that if you also install the Python 3 version, the pyloc2
command line driver will not work but the pyloc driver will point
to the Python 2 installation.
To uninstall it, you ca do:
$ python setup.py develop --uninstall
# And if you installed the Python 3 version
$ python3 setup.py develop --uninstall
However, this won’t remove the entry scripts generated by easy
install.

Known bugs

Classes or built-in types like int or str do not contain location
information. In this case pyloc tries to look for the name in the
AST. This procedure may not be accurate since Python is a dynamic
language.

Hacking
See HACKING for details.

Release notes
See the corresponding tag annotation. After cloning you can do for instance:
$ git show v0.1.10
