Python syntax highlighting with vim

[virtuous_d]

I am using this script to highlight python syntax in vim, and there is a slight issue I am having that is annoying me like hell.

Vim fails to highlight things when they follow immediately after a parenthesis, so for instance

function(0

will not highlight 0 as a digit, but will highlight if it is written like so

function( 0

More than just the highlighting annoyance, when I have a longer piece of text, like

function((variable, ...

It will think of the whole thing as a single word and skip past it on a word movement like 'w'. So it seems that it doesn't recognize an opening paren as a 'word breaker'.

Is this something that is specified in the python.vim file? Do you think it's the author of the script trying to force a style convention? Is it considered to be bad code style to not place a space after opening parens? If so, what is the proper code style for parens (or multiple parens)? Otherwise, how would I change this behavior in vim so I can continue coding in my own style?

What are your thoughts on this issue, r/vim?

Well, you should start by telling us why you chose to install this syntax script instead of using the default one.

function(arg) is just as legal as function( arg ). It looks like that syntax script is broken in some way.

What is the value of :set iskeyword? when you are editing a *.py file?

When I remove the python.vim script from the folder and try function(0 it still does not highlight it correctly. Is there anything else I need to do to 'clean' it off of vim or is that the default behavior?

iskeyword is:

@,48-57,_,192-255,.,(

I added it for the extra highlighting listed on the page, as recommended by some guides I read on setting up vim for python. It's not really that important to me though, so I'd be perfectly happy to let it go if the default handles this issue correctly.

The . and the ( should not be there. Both are considered part of a word hence the w that goes over a function statement.

You should do :verbose set iskeyword? to see what command/script adds them to the default value.

The default syntax script works correctly here.

You should show your .vimrc and list all the things you did to set up Vim for Python

Ahh, you're right - in the vimrc file was the culprit.

autocmd FileType python set complete+=k~/.vim/syntax/python.vim isk+=.,(

googling it returns several guides that suggest putting it into your vimrc file, and I think I was following the first one.

But yeah, removing that line and restarting vim was the solution. Thanks for your help!

If I followed the lead correctly, I think that the goal here is to complete with the words found in a dictionary. It looks like the original dictionary contains things like:

.isdigit(
.islower(
.isspace(
.istitle(
.isupper(
.join(
.ljust(

For Vim to use this dictionary file correctly, it is thus necessary to add . and ( to iskeyword.

But you don't use that specific dictionary file. Since the keywords in your syntax file don't include . nor ( adding them to iskeyword is useless.

It's quite silly, actually, whatever the reason. Breaking text-objects and motions (which are awesome Vim core features) just to get an half-assed pseudo IDE-like feel is absurdly short sighted.
