.toml

Rust, Python and Hugo configuration. Sections and keys in the outline, values in color.

Loper is a free, minimal editor for macOS that opens TOML instantly and colors every part of the file, so you find the value you need at a glance and can fix it right there. No IDE, no project to load, no gray wall of text.
