Highlighting is broken when strings contain the characters //:

The highlight chosen at the start of the domain name is:

hi<hjsonLineComment> trans<hjsonLineComment> lo<Comment>

Doing gg=G reveals the horrors of the broken indentation. I am unsure of wether it's a general issue or strictly an issue with NeoVim comparability.

NeoVim version: v0.10.0-dev

Syntax highlighting seems to change depending on where my cursor is in the file, which is ... strange, to say the least.

Tested on NVIM v0.10.0 and Vim 8.0. I see similar behavior on both, though the Vim 8.0 issue is subtly different, possibly due to different rerendering behavior.

NVIM v0.10.0

Vim 8.0

From the /try example on hjson.org, there is one section of output that looks odd in vim-hjson.

{
  # commas are optional
  commas:
  {
    one: 1
    two: 2
  }
}

Looks like this:

The one: 1 part shows the number without highlighting. My vimrc has this in it:

hi clear Identifier
hi clear Statement

But that doesn't seem to explain 1 lacking highlighting.

Apparently, syntax highlighting assumes presence of commas between list elements, which are optional in hjson.

I expect a closing bracket (of a list or object) to be displayed in same colors as a corresponding opening bracket.

Instead, closing } of some objects within a list AND the ] of that list are highlighted rather like string literals (at least in my colorscheme). To be precise, wrong } highlighting happens for objects:

1. followed by another object or string, but
2. not separated from it with comma nor comment.

Sample

According to https://hjson.github.io/try.html, this is a valid list of 6 elements — 5 objects and 1 string:

[
    {x:1}
    {y:2} {z:3}
    {z:4}
    "You are in a debris room filled with stuff washed in from the surface."
    {y:5}
]
