Syntax highlighting

crc highlights with tree-sitter, compiled from C source checked into the repository rather than taken as a crate. Every grammar is pinned by checksum in third_party/CHECKSUMS.

Languages

Language	Language server
Rust	rust-analyzer
Python	pyright
Go	gopls
C and C++	clangd
JavaScript and JSX	typescript-language-server
TypeScript and TSX	typescript-language-server
HTML, and Svelte and Vue files	none
CSS	none
JSON	none
TOML	none
YAML	none
Shell	none

Languages embedded in one another, such as CSS and JavaScript inside HTML, are parsed as themselves. That is also how .svelte and .vue files are highlighted: as HTML with script and style blocks.

Note

SQL is not in the alpha. A new language means vendoring its generated C and reviewing it, so the list grows deliberately.

The palette

The Graphite theme uses eight distinct hue families, in dark and light, so keywords, functions, types, properties, strings, numbers, constants and attributes are told apart by colour.

In the gutter

• Indent guides show the structure of the block you are in.
• The bracket pair around the caret is highlighted.
• Git marks show lines added, changed or deleted compared with HEAD, as you type.

Limits

Gutter marks compare with HEAD, not the index, and stop at 2 MiB. The bracket matcher counts its own pair only and does not skip strings or comments.
