python syntax highlighting

[Mathieu Roux]

Hello everybody,

I have re-installed my computer recently with kubuntu.
Now, when i use vim (python program with syntax highlighting), it
appears "S>" in the margin of my text (on the left).

I just don't know why some lines are marked "S>" and some other lines
are not marked.
And then maybe i should disable this mark, but i don't know how.

Thanks,
Mathieu

Have you installed a linter or some kind of a syntax checking plugin?
Something like ale or neomake or syntastic? If so, please check the
documentation of that plugin.

Best,
Christian

nothing like that...

i customized my .vimrc:

syntax on
syntax enable
let filetype_py = "python"
au FileType python nmap œ :w<CR>:!clear ; python3.9 "%"<CR>
au FileType python imap œ <esc>:w<CR>:!clear ; python3.9 "%"<CR>

When i execute my program with "œ", after that, there is always one
error in red in the bottom of the window.
"E:[1(#1)]"
and it seems that the error is also indicated by "S>" in red in the
margin...

With a C langage program (with customization), i don't have the same
problem.

That looks like the error comes from syntastic and is also displayed in
your statusline by vim-airline.

Are you sure you haven't installed any plugins? My guess you have at
least syntastic and vim-airline installed. Can you show the output of
`:scriptnames`?

Well, according to your :scriptnames output, you have installed it as
your distros package.

Here is airline.

Here is syntastic

I suggest, either getting yourself familiarize with the plugins (by
reading the documentation) or disabling those plugins or uninstalling
those packages.

Hello,

OK you're right, the problem was syntastic.

I can disable with

:SyntasticToggleMode


What can i type in .vimrc to disable syntastic automatically?

Thanks,
Mathieu

If you're not going to use Syntastic, why not un-install it?

Have you considered learning what Synstatic is trying to show you, could make you a better programmer.

[Mathieu Roux]

I have so less time... so many things to do...

Syntastic reproach me when i write
L = [ 1,2,3 ] in python
instead of
L=[1,2,3]

Put

let g:loaded_syntastic_plugin = 1

into your .vimrc

Or, disable this system plugin, by using Debians vim-addon-manager

~$ vim-addon-manager disable syntastic

or uninstall the plugin:

~$ sudo apt remove vim-syntastic
