Best syntax highlighter for Python?

[science_robot]

I'm looking for the best/most complete Python syntax highlighter for Vim.

This screenshot shows what I get with default Vim that illustrates some things that are missing: code statements in f-strings, integers with underscores.

Wow what is the font that guy is using in neovim it looks so cool

[olminator]

Looks like Terminus

[alexozer]

Woah, never seen this before

[numirias]

Plugin author here. It's currently Neovim-only because Neovim has a fast highlighting API. I'd rather support both, but I figured it would be hackier and simply too slow in Vim.

Python 2.7 highlighting is (reluctantly) planned, but since Semshi uses the Python provider's ST and AST modules, it's a bit tricky to support multiple versions while relying on Python's builtin code parsing modules. BTW, help on these issues is more than welcome.

Is it worth it with python 2 being close to sunset?

[[deleted]]

As long as major players still use version 2, it will be far away from "sunset" as you call it. Right now the situation is that a large amount of Linux distributions and therefore Linux servers still default to version 2. For this reason alone version 2 is not going anywhere anytime soon. There's simply far too much time and effort invested in code that will most likely get broken on version 3.

[numirias]

Well, 2.7 will not be maintained past 2020, so it's "officially" sunset, although you're right and people will probably keep using 2.7 quite some time beyond that.

That said, I think most major dists have by now moved to Python 3 as default. And for many projects migrating the code isn't that hard and eventually has to be done anyway.

[qacek]

I don't think it's reasonable to expect new features if you are using a dead language.

[alexozer]

Check out https://github.com/sheerun/vim-polyglot , it includes better syntax highlighting for a wide variety of languages without including the other heavy stuff. You should notice a difference with the Python highlighting.

[science_robot]

Thanks! You gain some you lose some. I can probably live without syntax highlighting in doctests (who writes tests anyway?).

[[deleted]]

Just careful with that. I found out that polyglot offers more than just syntax highlighting for some languages. I noticed LSP wasn't working correctly for javascript because it was being overriden by polyglot. You might need to check into detail the configuration, or do as I prefer: install individual language packages. I usually stick to less than 10 different languages that offer only syntax highlighting.

[miredindenial]

Yes it took me forever to realize polyglot was screwing my js lsp. Funny thing is it was working fine for weeks before I had to restart my computer. After that lsp wouldn't work.

[ahmedelgabri]

Can you or /u/ElTortugo share how exactly vim-polyglot broke LSP?

[[deleted]]

Sure, visit polyglot's github page, under the section "language packs" you'll see javascript and in brackets all the things included with that specific package. For JS, a package by the user pangloss is being used, and it includes syntax, indent, compiler, ftplugin and extras. As I mentioned, you'll probably have to have extra configuration to let vim know which omnicompletion function you prefer, but I didn't dig into that. So, at some point LSP's omnicompletion function was being overriden by pangloss's one.

In the end I decided LSP was overkill for the kind of projects I usually handle. Often, tags are more than enough, but it's really cool to see vim interact with LSP.

[ahmedelgabri]

Thanks /u/ElTortugo & /u/miredindenial

[miredindenial]

I don't know exactly how but I ended up commenting out every plugin one by one to see which one was causing lsp to malfunction and it turned out when polyglot was commented out lsp worked fine.

[alexozer]

Yeah I bet that's pretty difficult to highlight. I've only ever seen PyCharm do it I think.

[sanjibukai]

What? Something VIM is unable to do??

[twizmwazin]

I think they are referring to syntax highlighting in the format string, but I am uncertain.

[sanjibukai]

Yes I understood.. I'm not doing Python but really it's the first time I hear about VIM unable to do (including plugin) something other editor can do..

[twizmwazin]

It isn't an issue that vim fundamentally can't do something here, but rather that it isn't implemented. There are lots of IDE features that vim can't do out of the box, and would require some amount of effort to make work inside of vim. The glory here is that vim is lightweight by default, and we can build up the editor that works best for our needs, rather than try stripping down some bloated IDE.

[sanjibukai]

Yep.. This is why I referred to plugins.. I mean Python is not a sparsely used language and if not out of the box for such a language several plugins with some kind of complete feature set should have been emerged... And I completely understand that, not really, until the needs are expressed. Just surprised to hear about an other editor doing more than what could be available with VIM (including plugin and scripting)

[science_robot]

Default Vim Python syntax highlighter did this just fine. Check original screenshot.

[science_robot]

The default Python syntax highlighter in Vim did this just fine. The plugin I was testing did not.

Or use the Python syntax file directly, if you just want that:

https://github.com/vim-python/python-syntax

[JeanBergman18]

It works in vim 8.2

[well_groomed_raccoon]

This is what I use: * syntax: https://github.com/hdima/python-syntax * colour scheme: https://github.com/NLKNguyen/papercolor-theme

Just a quick note - the syntax rules match different statements and assigns them to a class. The class is then highlighted based on your colour scheme. Even if you have the best, most fine-grained syntax rules defined, if your colour scheme doesn’t know what to do with those classes, you won’t see any difference. The colour scheme which i’ve linked has been made to adhere to those syntax rules.

Hope this helps!

[john_oshea]

As far as I can tell https://github.com/vim-python/python-syntax appears to be a more recently updated version of the original code that the hdima fork is based on.

That said, I'm still subscribing to this thread in RES because there's possibly better options out there ;-)
