sublimelinter / sublimelinter-flake8

SublimeLinter plugin for python, using flake8.

SublimeLinter-flake8

This linter plugin for SublimeLinter provides an interface to flake8.

Installation

SublimeLinter must be installed in order to use this plugin.

Install via Package Control or git clone as usual.

Ensure that a flake8 is actually installed somewhere on your system. Typically, pip install flake8 on the command line will do that.

If you want to use a globally installed flake, make sure that it is available on the PATH. Before going any further, please read and follow the steps in "Finding a linter executable" through "Validating your PATH" in the documentation.

Otherwise configure "executable" or the "python" setting.

If you use pipenv, and you're working on a project with a Pipfile, everything should be automatic.

Settings

• SublimeLinter settings: http://sublimelinter.com/en/latest/settings.html
• Linter settings: http://sublimelinter.com/en/latest/linter_settings.html

Additional settings:

• ignore_fixables (default: True): filter warnings that Sublime can fix automatically (e.g. trailing white-space) on save.

SublimeLinter-flake8 works with common flake8 configuration files and inline overrides. Note that by default the working dir is set to an open folder attached to the current window of Sublime. Edit this setting if your config files are located in a subfolder, for example.

Use "args" if you want to pass additional command line arguments to flake8.

Compatibility with --per-file-ignores and other flake8 plugins

SublimeLinter-flake8 is compatible with most flake8 plugins out of the box. However, plugins that rely on selecting or ignoring certain files based on filename may appear to be "broken" due to the way SublimeLinter runs during linting. This includes flake8's own --per-file-ignores option introduced in 3.7.0, as well as plugins such as flake8-aaa and flake8-pyi.

To make the source filename available to the flake8 executable again, pass the --stdin-display-name option using SublimeLinter's "args" setting:

"args": ["--stdin-display-name", "${file:stdin}"]

Including the :stdin fallback ensures that files that have yet to be saved are still linted.

sublimelinter-flake8's Issues

no such option --max-complexity

I just installed the latest version this package and here's the error i have:

flake8: error: no such option: --max-complexity

My env:

• python 2.7.3
• flake8 2.4.0
• pep8 1.5.7
• mccabe 0.3
• pyflakes 0.8.1

Is there any setting i can override?

SublimeLinter is calling Flake8 with the system python instead of the Virtualenv

I install flake8 in a virtualenv using pipsi. This sets up a bin directory in my path to call python scripts but keeping them isolated in virtualenvs.

It works fine when flake8 is run normally:

kstone@kstone-mbp ~> which flake8
$HOME/.local/bin/flake8
kstone@kstone-mbp ~> flake8 --version
2.5.0 (pep8: 1.5.7, pyflakes: 1.0.0, mccabe: 0.3.1) CPython 2.7.10 on Darwin

But SublimeLinter uses the system python (if another one isn't configured) rather than calling the entry point directly and thus doesn't register the appropriate virtualenv:

SublimeLinter: flake8 version query: /usr/bin/python $HOME/.local/bin/flake8 --version 
SublimeLinter: WARNING: no flake8 version could be extracted from:
Traceback (most recent call last):
  File "$HOME/.local/bin/flake8", line 7, in <module>
    from flake8.main import main
ImportError: No module named flake8.main

Basically it's calling python ~/.local/bin/flake8 instead of just executing ~/.local/bin/flake8

Override possible user formatting

If we pass --format default we will (hopefully) override any formatting a user may have set in its config file. We need the default style, otherwise our regex can't match.

Show error code in popup box

Would make it much easier to know which codes to ignore. An example of the popup menu I'm talking about:

I think https://github.com/dreadatour/Flake8Lint has this built in.

Missing docstring in public module

SubmlimeLinter-flake8 throws an error "missing docstring in public module" on all the files. I don't see this error when i run flake8 on the terminal.

flake8 --version 3.2.1 (pyflakes: 1.3.0, flake8-docstrings: 1.0.2, pydocstyle: 1.1.1, mccabe: 0.5.2, pycodestyle: 2.2.0) CPython 2.7.9 on Darwin

pep8 --version 1.5.7

SublimeLinter-flake8 doesn't support extra flake8 extensions

I installed flake8 via pip + the following extensions:

cvirus@leon:~$ flake8 --version 2.2.5 (pep8: 1.5.7, import-order: 0.5.1, pep257: 0.2.1, mccabe: 0.2.1, pyflakes: 0.8.1, naming: 0.2.2) CPython 2.7.6 on Linux

Unfortunately, SublimeLinter-flake8 will only highlight the errors for pyflakes, pep8, and mccabe .. While the rest of the extensions have no effect, except for the "import-order" extension where its errors are only shown in SublimeText console but are not highlighted in the editor:

SublimeLinter: flake8: models.py ['/usr/bin/python', '/usr/local/bin/flake8', '--config=setup.cfg', '--jobs=1', '-'] SublimeLinter: flake8 output: stdin:2:1: I100 Imports statements are in the wrong order. from django.conf should be before from django.db

If I run flake8 from the command line, I get the following:

cvirus@leon:~/projects/fer2etak$ flake8 fer2etak/nada/models.py fer2etak/nada/models.py:1:1: D100 Docstring missing fer2etak/nada/models.py:2:1: I100 Imports statements are in the wrong order. from django.conf should be before from django.db fer2etak/nada/models.py:6:1: D101 Docstring missing fer2etak/nada/models.py:10:1: D102 Docstring missing fer2etak/nada/models.py:14:1: D203 Expected 1 blank line *before* class docstring, found 0 fer2etak/nada/models.py:14:1: D204 Expected 1 blank line *after* class docstring, found 0 fer2etak/nada/models.py:14:1: D400 First line should end with '.', not 'g' fer2etak/nada/models.py:29:1: D102 Docstring missing fer2etak/nada/models.py:33:1: D101 Docstring missing fer2etak/nada/models.py:38:1: D102 Docstring missing

Non of the above errors are highlighted in the editor.

Is this a bug or I'm missing something ?

SublimeLinter-flake8 not finding paths

First of all thank you for SublimeLinter and thank you for extending it with Flake8, as it makes coding Python in Sublime so much more enjoyable!

I believe I have a problem with my paths settings of SublimeLinter-flake8.
This expresses itself in:

• Python 3.6 syntax (e.g. "f-strings") marked as erroneous
• imports from a module folder I have included in the PythonPath also being marked

Both sublime-anaconda and python itself do not express any problem with the respective python files.
(Anaconda understands the Python 3.6 syntax and autocompletes with content from the extra folder. Python itself can execute the scripts without any error.)

Tell me what information you require to understand this problem and I will provide it.
Thanks.

Below are two links to threads on Sublime Forum and stackoverflow respectively where I discuss this issue.

They also contain an excerpt from my sublime-linter's .sublime-setttings file.

Compatibility with Djaneiro

Hi,

When installing the Djaneiro plugin flake8 stops finding errors inside .py files. It seems it has to do with the new tmLanguage that Djaneiro adds: "Python Django". Would it be possible to add highlighting to files with the "Python Django" syntax, and not only "Python"? Would love to use SublimeLinter-flake8 together with Djaneiro!

Thanks for your great work!

ignore "line too long"

I want to ignore "line too long" messages but for some reason it doenst work.
This is from my SublimeLinter.sublime-settings:

"flake8": {
    "@disable": false,
    "args": [],
    "builtins": "",
    "excludes": [],
    "ignore": "E501",
    "jobs": "1",
    "max-complexity": -1,
    "max-line-length": null,
    "select": ""
},

The error code E501 is correct (I think) - if I enable debug mode and open the console:

script.py:26:80: E501 line too long (97 > 79 characters)

SublimeLinter-flake8 not working with flake8 2.2

Hey there guys, great extension.

Unfortunately it seems that flake8 2.2.0 has broken it. The extension appears to search for flake8-script.py which doesn't exist in the 2.2.0 release and therefore flake8 is simply not found at all.

Rolling back to flake8 2.1.0 works as expected:

pip install flake8==2.1.0

Any help would be greatly appreciated 😄

[Help/question] How to persist gutter or outlines?

After a linting is done, the gutters and outlines are shown. But once I start typing again, all of them are gone, and I have to save to lint again. What I want is: when I start typing, only the gutter / outline of that specific line disappear, and others remain unchanged. If this cannot be achieved, then I want all the gutters / outlines to remain the same when I start typing.
Is that possible? Thanks

Add setting to deactivate the inline error message popups.

Ever since a recent-ish update to SublimeLinter-flake8, there's an intrusive inline popup that shows up while I am typing. It's especially bad because it overrides SublimeText's auto-complete box. I can't find a way to deactivate it.

SublimeLinter already has an option to lint on save and to show a popup when a lint happens. Why is this functionality replicated in SublimeLinter-flake8?

Automatically ignore some whitespace errors

For good reasons, settings like max-line-length and max-complexity should be not held within sublime settings, but in .flake8 or another config file.

The exception here should be the typical whitespace warnings Sublime will autocorrect for us on save. These are:

W291	trailing whitespace

W293	blank line contains whitespace

W391	blank line at end of file

Does nto work with flake8 2.2.3

The whole process just hangs and nothing happens.

(2.2.2) does work

Linter always uses /usr/local/bin/flake8

Hi,

At some point in the recent past, sublimelinter started choosing /usr/local/bin/flake8 regardless of the @python version I have specified in my project settings. I think the linter used to use the python module (i.e. python -m flake8) with the correct python version.

While I have flake8 installed for both python2 and 3, /usr/local/bin/flake8 only works for the one I've most recently installed it for, since the pip install seems to put the python version in the shebang of that script, like so:

#!/usr/local/opt/python/bin/python2.7

# -*- coding: utf-8 -*-
import re
import sys

from flake8.main.cli import main

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
    sys.exit(main())

This makes flake8 linting not work for python3, or vice versa depending on what I've installed last.

I've tried a few different things, such as setting @python inline, changing my shebang lines in scripts to a versioned python (i.e. #!/usr/local/bin/python3), but /usr/local/bin/flake8 is always chosen as the linter.

I'm running python 2.7.12 and 3.5.2 installed via Homebrew on OSX 10.11, in case that information is relevant. I'm running the latest build of ST3, and SublimeLinter 3.7.4, and SublimeLinter-flake8 2.0.1

Let me know if I can provide further information.

show-code option is not working

Setting show-code option doesn't work, breaking also the whole linting.
Here is the error from console:

SublimeLinter: flake8: vminfo_quick.py ['/usr/bin/python2.7', '/usr/local/bin/flake8', '--ignore=F403,E111,E113', '--max-line-length=100', '--jobs=1', '--max-complexity=-1', '--show-code=True', '-']

Misleading info about @python setting

The README.md reads:

@python A meta setting that indicates the python version of your source files. Use this inline or at the global level, not within the linter’s settings.

Why should I not use it within the linter's settings (works fine for me BTW)? And how would I set it at global level instead?

D400 on shebang line

Reports that the line should end with a period which would screw up the syntax of the shebang line. Probably not optimal advice.

E999 Syntax error is reported as a warning

From http://flake8.pycqa.org/en/latest/user/error-codes.html

We also report one extra error: E999. We report E999 when we fail to compile a file into an Abstract Syntax Tree for the plugins that require it.

Highlighting wrong occurrences of unused import

I am not sure if this is a bug with sublimelinter-flake8 or flake8

SystemError on Flake8 Linter Reload

I'm using python 2.7.6, getting the following SystemError:

util.py is unloaded and reloaded at startup

When ST "reloads" plugins at startup if a plugin is already loaded it will unload it then reload it. linter.py imports util.py so it gets loaded, when ST then tries to load util.py it sees that it's already loaded so it unloads it and then reloads. This is extra overhead and can cause side-effect hard-to-debug issues.

ST only autoloads modules in the root package so the fix is to move util.py into a sub directory or move the code into linter.py.

I don't know when I'd get a chance to submit a PR or which fix you'd prefer. Looking at the code in util I'd just push the code into linter.py, it's not a huge amount of code.

Adding custom flake8 args in Python3

Hey!

I've just bumped up to Python3 and have found that I can no longer pass extra args to flake8 via the SublimeLinter plugin.

I'm currently defining args in my SublimeLinter prefs as so:

"args": [
    "--radon-max-cc",
    "6"
]

Looking at the logs in debug mode - Python2 shows something like this:

SublimeLinter: flake8: list_.py ['/python2.7/bin/python', '/python2.7/bin/flake8', '--radon-max-cc', '1', '--max-complexity=-1', '--jobs=1', '--max-line-length=100', '--ignore=P101,P102,P103', '-']

However, in Python3, it looks to be operating in a totally different manner:

SublimeLinter: flake8: list_.py <builtin> 
SublimeLinter: flake8 options: {'max_line_length': 100, 'jobs': '1', 'reporter': <class 'SublimeLinter-flake8-master.linter.Flake8.get_report.<locals>.Report'>, 'max_complexity': -1, 'ignore': ['P101', 'P102', 'P103']}

I'm struggling to see how I should be passing through the custom arguments!

Any help would be much appreciated.

Cheers,
Ian

Doesn't work, no errors

In the readme it says I

must ensure that flake8 is installed on your system.

However, before I installed flake8 to my local Python dist, the following was output to my console:
SublimeLinter: flake8 enabled: (None, None)
I do not think this message is useful because linting does not work even though I don't get an error. Also, when installing from within Package Control you don't get to see the readme.

Later, as I installed it, the message would turn into
SublimeLinter: flake8 enabled: ('c:\\Python33\\python.exe', 'c:\\Python33\\Scripts\\flake8-script.py')
yet it still doesn't work. It also appears that setting "@python": 2 in the user settings does not change the above to my 2.7 dist.

Note that it did work with the built-in Python and the flake8 version from Python Flake8 Lint until I figured out this was because I didn't restart ST after disabling the package.

Then, if I were to specify other versions of Python on my system (2.7, 3.2 and 3.3 are available), where would I tell the linter where they are? Found it here.

And finally: Is it possible to flag a single file as being Python2? Does it read the #!/usr/bin/env python3 line? It seems like you can only set that for the whole project and directory.

console spam

I'm seeing this a lot in sublime's console

SublimeLinter: flake8: wanted @python is 'None' 
SublimeLinter: flake8: trying to use globally installed flake8 
SublimeLinter: flake8: wanted @python is 'None'

SublimeLinter: flake8: trying to use globally installed flake8 
SublimeLinter: flake8: wanted @python is 'None' 
SublimeLinter: flake8: trying to use globally installed flake8 

Is there a way to get rid of this? I'm usually connected to Maya and have it's console report back to sublime's console and this is getting in my way.

Any idea what could cause this or how to start to diagnose the problem?

Flake8 2.5.1 isnt working

Have you seen this issue?

SublimeLinter: debug mode: off 
SublimeLinter: WARNING: import of flake8.engine module in flake8 failed, linter will not work with python 3 code 
SublimeLinter: WARNING: flake8 deactivated, cannot locate 'flake8@python'

Color errors based on severity

It would be nice if this linter color-coded errors based on severity, or the exact linter the error originated from (pep8 vs pyflakes vs mccabe). In general, I care far more about a pyflakes error than pep8/mccabe, since a pyflakes error usually means my code will error out.

Version conflict with flake8-3.0.0b1

Versions..

OS: OS X 10.10.5
Sublime Text: v3 build 3114
Sublimelinter Plugin: 3.7.4
Sublimelinter-flake8 Plugin: 2.0.1
system flake8: 3.0.0b1

Work-around: I dropped back to flake8 v2.4.1 and seems to be working just fine.

Import of flake8.engine module in flake8 failed

I followed the instructions in the README exactly and have ran into this issue after installing:

I have added the @python directive to my Sublime settings as well as the SublimeLinter settings.

Getting RunTime error on install

I'm trying to install via Package Control; I first install SublimeLinter 3. Then installed SublimeLinter-flake8. I get this error in the console:

This is my first time using SublimeLint and am not sure what to do ... it doesn't appear to be working. Have tried this on two different machines. After this error I don't see SublimeLinter-flake8 in my Library/Application Support/Sublime Text 3/Packages. And every file I check it says "no errors".

Thanks for your help.

Plugin tries to run flake8 in python2 instead of python3

I was a happy SublimeLinter-flake8 user, once..

Some days ago it stopped working (don't know when exactly), fiddling around I discovered that the plugin tries to launch flake8 inside python2 instead of python3.

If I start up Sublime (with Sublimelinter "debug": true) I have the following output in the console:

Yay, looks great, the SHELL is discovered correctly, as well as all system PATHs..

    from flake8.main import main
ImportError: No module named flake8.main

I have flake8 installed (via pip3 install -U flake8), it also works correctly (if called manually from the commandline).

Steps I've already tried:

• Putting an "@python": 3.5 metavar inside the SublimeLinter config, tried any level
  • no success
• Reinstall SublimeLinter-flake8
  • no success
• Reinstall flake8 (as well as pep8, pyflakes & mccabe)
  • no success
• Reinstall SublimeLinter
  • no success
• Complete reinstall of Sublime, importing my old settings afterwards.
  • no success! surprise!

What am I missing, what am I doing wrong?
Please help me become a happy user of SublimeLinter-flake8 again.

Recent update breaks the plugin

No highlight on unused imports

I know there are some opened issues about wrong highlight on unused imports, but I think this one is different.
If I have the import clause separated on multiple line, there will be a gutter showing a warning sign. But there will be no keyword highlighted, thus you cannot use Ctrl + K, n to jump to that warning.

The screenshot is as followed:

Support custom builtins

Please add an builtins option (like for ignore) to the linter to suppress warnings of known but not defined globals.

Can't disable E501

Hi, and thanks for reading.

So, I just upgraded to Sublime Text 3 and installed SublimeLinter via Package Control.

I just noticed that now, SublimeLinter takes into account E501, but that disturbs me and I would like to disable it (disable the warning).

I installed pip, pep8 and SublimeLinter-pep8 too

Here's my SublimeLinter.sublime-settings :

{
"user": {
"debug": false,
"delay": 0.25,
"error_color": "D02000",
"gutter_theme": "Packages/SublimeLinter/gutter-themes/Default/Default.gutter-theme",
"gutter_theme_excludes": [],
"lint_mode": "background",
"linters": {},
"mark_style": "outline",
"no_column_highlights_line": false,
"passive_warnings": false,
"paths": {

"osx": [],
"windows": []
},
"python_paths": {
"linux": [],
"osx": [],
"windows": []
},

"shell_timeout": 10,
"show_errors_on_save": false,

"magicpython": "python",
"php": "html",
"python django": "python",
"pythonimproved": "python"
},
"warning_color": "DDB700",
"wrap_find": true
}
}

What should I add to disable E501 ? I tried everything I could find on the Web...

PS : Sorry for my bad english

linter ignores flake8 plugins

I get a different output from running the flake8 command on the terminal compared to what sublimelinter tells me. For example:

$ flake8 public
public/admin.py:3:6: H304  No relative imports. 'from .models import PublicPicture' is a relative import

I've tried to specifically include 'H' errors in the settings, but it still doesn't show up:

"settings":
    {
        "anaconda_linting": false,
        "SublimeLinter": {
            "debug": true,

                "flake8": {

            },
        },
        "python_interpreter": "/Users/dries/src/csm/_csm/bin/python"
    }

Is this plugin not expected to show warnings/errors displayed by flake8 plugins?

The plugins I'm using for flake8 are these:

$ flake8 --version
2.5.5 (pep8: 1.5.7, mccabe: 0.2.1, hacking.core: 0.0.1, ProxyChecker: 0.0.1, pyflakes: 0.8.1) CPython 2.7.12 on Darwin

The specific plugin that warns about relative imports is 'hacking.core'. Or is there maybe a better way to enforce this coding style: http://docs.openstack.org/developer/hacking/

~/.config/flake8 config file not working

Hello!

Flake8 usually reads configuration options from ~/.config/flake8 but when used with SublimeLinter-flake8 it seems as if the file wasn't been loaded.

Is that expected? How can I get it to read the file?

Thanks

No longer works with flake8 2.1

Despite what the readme says, this package is broken on flake8 2.1:

SublimeLinter: flake8: wanted executable is '/usr/bin/flake8' 
SublimeLinter: flake8: __init__.py ['/usr/bin/flake8', '--jobs=1', '--max-line-length=79', '--max-complexity=15', '--ignore=E303,E501', '-'] 
SublimeLinter: flake8 output:
Usage: flake8 [options] input ...

flake8: error: no such option: --jobs 

Perhaps this flag only exists for the python3 version of flake8?

Wrong word highlighted on F401

Note that the first instance of "static" is highlighted, but it is the second instance that is the issue.

Better support for config files like `.flake8`

flake8 supports various config files out of the box, e.g. .flake8. But command line args have precedence over config file settings, and all settings within the SublimeLinter framework will end as command line args. This leads to a bad default UX bc this linter unfortunately applies some default settings on its own.

SublimeLinter-flake8/linter.py

Lines 57 to 59 in adb4890

	'--max-line-length=': None,
	'--max-complexity=': -1,
	'--jobs=': '1',

We should therefore remove all default settings, t.i. set them to the empty string, so that by default the typically settings in tox.ini, .flake8 or setup.cfg will kick in.

IMO it should be best practice anyway to keep these settings outside of Sublime text bc the other people already use vscode ;-)

setup.cfg flake8 settings ignored when using module instead of executable

My project wide flake8 settings are defined in a setup.cfg:

[flake8]
max-line-length = 100

This worked fine when I was using python2 flake8 (presumably as the executable was used), but now I've switched to a python3 flake8 these settings are being ignored:

SublimeLinter: flake8: __init__.py <builtin> 
SublimeLinter: flake8 options: {'max_complexity': -1, 'reporter': <class 'SublimeLinter-flake8.linter.Flake8.get_report.<locals>.Report'>, 'jobs': '1'} 
SublimeLinter: flake8 output:
__init__.py:106:80: E501 line too long (99 > 79 characters)
__init__.py:129:80: E501 line too long (99 > 79 characters)
__init__.py:164:80: E501 line too long (82 > 79 characters)
__init__.py:165:80: E501 line too long (84 > 79 characters)
__init__.py:198:80: E501 line too long (99 > 79 characters)

I prefer using setup.cfg for settings as they will also apply for flake8 runs from the command line or travis.

shebang of source is ignored

Cannot configure the last version (for sublimelinter 3) to work with shebang.

I'm on Windows and before (with my PR):
When my script start with #!python3, flake8 from python3 is used.
When no shebang or start with #!python2, flake8 from python2 is used.

It seems to me that shebang is now totally ignored, probably because the @pyhon was removed from cmd = ('flake8@python', '*', '-')
