andviro / flake8-vim Goto Github PK

Right now whenever I run PyFlake the file is immediately written to the filesystem, the result is that when I'm simply checking the file it automatically writes to the filesystem which (in the case of syntax errors) results in my development server crashing because it auto-reloads on file changes.

If the command has to write for it to work, can it write to a temporary file instead perhaps?
The better solution would be to pipe the data straight towards the flake8 stdin imho, but not sure if that's too easy to integrate into the current script.

The flake8 command at least supports this using the following syntax:

cat some_python_file.py | flake8 -

If I read 005ecfa correctly, I should be able to select an error and press shift-q to fix it. If I for example remove the : after an if statement and run :PyFlake to get the error, then select the line with the error and press shift-q I get "syntax error". Any ideas? Did I misunderstand?

I would like to help integrate this project:
https://github.com/openstack-dev/hacking

Into flake8-vim. I would love to drive this forward if you could offer advice/assistance.

Hi,

autopep8 is replacing pep8 continued_indentation with its own function

del pep8._checks['logical_line'][pep8.continued_indentation]
pep8.register_check(continued_indentation)

The problem is that the function from autopep8 does not explain the error, instead it only prints the error code and the indent level e.g. E125 {0}.

If one is currently using python-mode with vim (7.4) and they have the following in their vimrc

let g:pymode_rope = 1
let g:pymode_lint = 1

They get the following error with flake8-vim,

Error detected while processing function pymode#buffer_post_write:
line    2:
E121: Undefined variable: b:pymode_modified
E15: Invalid expression: b:pymode_modified && g:pymode_rope_regenerate_on_write
line    8:
E121: Undefined variable: b:pymode_modified
E15: Invalid expression: g:pymode_lint_unmodified || (g:pymode_lint_on_write && b:pymode_modified)

One way to resolve the issue is to do,

let g:pymode_rope = 0
let g:pymode_lint = 0

If I have a Tagbar split opened, flake8-vim opens the quickfix only below the half-screen window. I expected it to use the full width of vim.

After updating to the latest commit, I get the behaviour seen here:

Note that I am just typing signals. and not hitting return anywhere. I am trying to type signals.post.

I reverted back to 7cecb3a and I'm no longer having the problem.

I've just installed flake8-vim with Vundle. After :PyFlake I am getting following errors:

Am I doing something wrong or is it some kind of a bug?

I just searched the code and don't see it being used anywhere. I would use it if it worked.

As you can see, after deleting the two lines that are marked as errors, the import os line is now marked as an error which is incorrect. Only after saving the file again it is marked as correct again. But in some cases that doesn't happen either.

Any idea what could be wrong with my config? Or is it a bug?

Can you auto-update flake8-vim when dependencies packages are updated ?

I see we currently use Frosted 1.4.0, when I wish to use v1.4.1 (for the noqa feature).

Thanks
Cordially

PyFlake doesn't seem to handle the syntax(?) error of defining a function where a variable with a default value is followed by a variable without a default.

Minimal code to reproduce

def failure(var1="test", var2):
    pass

When I install via vundle or copy ftplugin in vim folder the plugin is not loaded. I have filetype plugin indent on. I see the vim file is quite deep in the directory. Could it be the issue ? How can I fix that ? I have vim 7.4.52

Hello -- first of all, thanks for the amazing plugin, I love it so far!

I just had a quick note/question. If I select the entire file in visual mode and run PyFlakeAuto, it doesn't seem to auto-correct everything. In my case, it simply fix whitespace errors like adding extra blank lines or removing trailing whitespace. Is there a config that changes this?

I was also wondering if there is a way to run the same command whenever a python buffer is saved.
Thanks again for making such a great plugin!
