Python Checker

A maintainable Python code checker for Sublime Text 3

Once the plugin is installed, it will highlight common problems in your Python code.

Internally it relies on the wonderful pyflakes and pep8 packages.

Installation

Use Package Control.

Python version

By default Python Checker will use the version of Python that came with Sublime Text 3. This currently means Python 3 and can result in problems like undefined name 'unicode' being reported. If you want to use a different version, set the python_interpreter_path option in your project settings:

# <project name>.sublime-project
{
    "settings": {
        "python_interpreter_path": "/usr/bin/python"
    }
}

This is compatible with other plugins including SublimeJEDI.

PEP8 checks

Use the standard pep8 configuration files to control the behaviour including skipping some checks. An example project configration might look like this:

# setup.cfg or tox.ini
[pep8]
ignore = E501,W191
max-line-length = 120

pythonchecker's Issues

undefined name - raw_input

For some reason, raw_input is undefined.
I'm using python 2.7 and SE3

Attribute called "None" is misinterpreted to be a syntax error

If I have a class whose instances have an attribute called None (don't ask, not a class I've made) like so:

class X:
    def __init__(self):
        self.None = True

Python Checker will say "invalid syntax" while it's actually proper code, just not recommended.

Same will happen if I access it through an instance:

x = X()
print(x.None)

Doesn't seem to recognise basestring

Basically the subject says it. When using something like isinstance(s, basestring), the plugin raises an error.

KeyError while highlighting problems

It doesn't happen every time. I'm not sure yet how to re-create it.

Writing file /home/szuliq/source/…/views.py with encoding UTF-8 (atomic)
Traceback (most recent call last):
  File "/opt/sublime_text/sublime_plugin.py", line 263, in on_post_save_async

Check as you type

If we get async checking (issue #3), we can use a timer to re-check the source when the user pauses typing.

Async checking

subprocess.check_output() stalls the host process. It would also be nice to be able to cancel the check and kill the process.

Manual Installation

Is there any way I can install your plugin manually?
I can't make Package Control to show up in Command Pallet no matter what I try including removing it from "ignored_packages" list

Question: pep8 settings get ignored & pyflake errors won't show up.

I just installed PythonChecker under a fresh Sublime 3 install trough Packet Control.

Using pep8 and pyflakes standalone works as expected.

I store my configuration (mainly some ignores) under ~/.config/pep8.

When I manually (command line) check with pep8 I get no errors and 2 with pyflakes (I intentionally mistyped one import). Opening the source in Sublime, I get a lot of pep8 errors and no pyflakes errors.
