sollniss c76594af82 go: Highlight predeclared types and built-in functions (#59780)
Tag Go's universe-scope identifiers as @type.builtin and
@function.builtin, matching Rust, TypeScript, and Python grammars (and
upstream tree-sitter-go / nvim-treesitter / Helix). Themes already style
these captures, so Go was the only major language not distinguishing
built-ins.

# Objective

Adds support for `@type.builtin` and `@function.builtin` targeted syntax
highlighting.

## Solution

Defined builtin functions and types in Go's highlights.scm.

## Testing

All screenshots are with `"semantic_tokens": "off"`. Built with
`--release` flag.

Licensing

Zed source code is licensed primarily under GPL-3.0-or-later, with Apache-2.0 components where marked.

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.

Sponsorship

Zed is developed by Zed Industries, Inc., a for-profit company.

If you’d like to financially support the project, you can do so via GitHub Sponsors. Sponsorships go directly to Zed Industries and are used as general company revenue. There are no perks or entitlements associated with sponsorship.
