regression: all import statements are highlighted with red.

[aslushnikov]

I bisected this down to this commit: 169f678

Repro:

• install tip-of-tree typescript-vim
• open a simple typescript file:

import fs from 'fs';
import path from 'path';

This is what it looks like on master:

This is what it looks like with 31ede5a:

same issue here, took me a while to realize it's typescript-vim causing this.

the fix seems to be:
change "if version < 508" to "if version >= 508"
in syntax/typescript.vim

The suggested fix changes this syntax to use highlight link instead of highlight link default, which would be better done by removing the condition completely as we can assume everyone is on a newer version than vim v5.08.

But, as commit #169f78 says, syntax files that replace default syntax files usually use highlight link default all the time. So perhaps this isn't the right fix.

[leafgarland]

As an aside. Have you tried the default typescript syntax that is now distributed with vim/nvim? It might work as well or better?

Also, if you are using neovim then you could use the treesitter syntax which is likely to be faster. I switched to treesitter highlighting some time ago.

When this syntax was first created (back before typescript's 1.0 release) there were no other options but there are now.

The issue doesn't occur on my Mac setup

> vim --version
VIM - Vi IMproved 9.1 (2024 Jan 02, compiled Jan 23 2024 22:19:02)
macOS version - arm64

For my Alpine desktop however, it does! Also checked on ubuntu containers! Same issue
switched to HerringtonDarkholme/yats.vim and it solved the issue.

@laoshaw Checkout these lines on /usr/share/vim/vim90/syntax/typescript.vim

" This is the same syntax that is in yats.vim, but:
 12 " - flattened into one file
 13 " - HiLink commands changed to "hi def link"
