A simple Tree Sitter-based Nova extension providing editor support for TOML files.
TOML (Tom's Obvious Markup Language) is a very straightforward and, according to Tom, obvious syntax.
Given the relative simplicity of the syntax, this extension is pretty much considered feature-complete. Any future updates would likely only focus on integrating additional IDE-like functionality and keeping up with any relevant changes introduced in Nova's extension API.
Beyond syntax highlighting, this extension also includes very basic implementations of the following features:
- Code folding
- Symbolication
NOTE: this extension is only supported on Nova v10.0 and higher
There already exists a TOML language extension in Nova but it has one really annoying bug which inserts \# instead of # when commenting. That extension doesn't appear to be maintained though, so I thought I'd just keep a local fork of it with that one character removed.
However, since the new Tree Sitter language system was released in Nova 10.0 the same day this was written, I figured I might as well try and compile an existing Tree Sitter grammar for TOML and publish it since the highlighting is more complete.
I've tried to keep the same highlighting selectors/colors as the existing extension, although this syntax also adds highlighting of some value types (numeric, datetime, and other literals) that it didn't pick up.
The TOML syntax used by this extension is located at nlydv/tree-sitter-toml and linked here as a submodule. It's a lightly modified fork of ikatyang/tree-sitter-toml that exposes additional nodes in the syntax tree for queries to hook into.
git clone https://github.com/nlydv/nova-toml
cd nova-toml
git submodule update --init
./build.shThen, to install the built extension:
open TOML.novaextensionNova should launch (if not already running) and ask you to confirm.
