TOON for Sublime Text

Syntax highlighting for TOON (Token-Oriented Object Notation) in Sublime Text - and in bat, which reads the same .sublime-syntax format.

Installation

Package Control

Once the package is accepted: Command Palette > Package Control: Install Package > TOON.

Manual (Sublime Text)

Clone into your Packages/ directory as TOON (macOS path shown):

git clone https://github.com/mpgirro/sublime-toon-syntax.git \
  "$HOME/Library/Application Support/Sublime Text 3/Packages/TOON"

bat

Until bundled with bat itself, install as a local syntax:

mkdir -p "$(bat --config-dir)/syntaxes"
git clone https://github.com/mpgirro/sublime-toon-syntax.git "$(bat --config-dir)/syntaxes/sublime-toon-syntax"
bat cache --build
bat sample.toon   # highlighted

What gets highlighted

Comments, keys (quoted and unquoted), array headers with length markers [N], delimiter markers (, / tab / |) and {field,lists}, list items and their payloads (- key: value, nested headers), double-quoted strings with escape validation, numbers, true/false/null, inline primitive arrays (tags[3]: a,b,c), and tabs in indentation flagged as invalid.

Tabular rows are delimiter-aware: only the delimiter declared in the header separates cells, and primitives highlight as complete cells only - v1.2 stays plain, 7 lights up (see docs/adr/0003-delimiter-aware-rows.md).

Development

# Symlink for live development (macOS); the name TOON matters
ln -s "$PWD" "$HOME/Library/Application Support/Sublime Text 3/Packages/TOON"

Tests live in syntax_test_toon.toon. Run them inside Sublime via Tools > Build, or headlessly with syntect's test runner (this also proves bat compatibility):

git clone --depth 1 https://github.com/trishume/syntect.git
cargo build --example syntest --manifest-path syntect/Cargo.toml
mkdir -p /tmp/pkg && ln -sfn "$PWD" /tmp/pkg/TOON
syntect/target/debug/examples/syntest syntax_test_toon.toon /tmp/pkg
