This is a re-do of #7888 Outside a call, the grammar scoped a name as a type or a variable by its capitalization. A theme could not distinguish a type from a value with the same spelling, or a parameter, a member, or an implemented interface from any other name. Pointer member access `->` was scoped as a result arrow, which scoped `Lookup` in `regions->Lookup(x)` as a type. `entity.name.type` now applies only in a type position (after `:`, `->`, `as`, `adapt`, or `require`, or in an `impl`) and to the name a nominal declaration declares. A qualifier, in a declared name like `fn N.Base(T: type).F()` or in a type, is `entity.name.scope-resolution` nested in `entity.name.type`. As in the parser, a name is a qualifier when its parameter lists are followed by `.`. Parameters, `let` bindings, choice alternatives, members, implemented interfaces, primitive types, `import`, and the strings naming a builtin or a library have their own scopes, and brackets use the C++ grammar's scopes. A `->` written directly after its operand is member access; no result arrow in the repository is written that way. The sample palette renders each scope that depends on context differently, and `tmlanguage.py` now supports nested captures. In 17 of the 19 themes measured, the VS Code built-ins plus One Dark Pro, Night Owl, Tokyo Night, and Nord, 13% to 27% of the characters in hand-written Carbon change color or style. A theme loses a color where `.` is now punctuation, where word operators like `as` are no longer control-flow keywords, or where a name outside a type position is no longer a type.

Carbon Language
This extension provides support for the Carbon Language.
This extension is currently experimental, and being developed alongside Carbon.
Quickstart
- Download and install a
carbonrelease.- By default, the extension will look for
carbonunder./bazel-bin. This is for developers actively working on Carbon and running VS Code inside a carbon-lang clone.
- By default, the extension will look for
- Install the Carbon Language extension.
- Configure the installed path to
carbon.
Configuration
The configuration is under carbon.*. At present, the only configuration is the
path to the carbon binary. This looks like:
"carbon.carbonPath": "/path/to/carbon"
Communication
See Carbon's
collaboration systems.
We're most active on Discord and have a
#editor-integrations channel. We'll also respond to questions on
GitHub Discussions.
Documentation
Carbon currently only has project-level documentation. See the GitHub repository.
