This extension supports .tpz files with syntax highlighting, a file icon, comments, brackets, snippets, and diagnostics from the language server in an installed Topaz toolchain.

Requirements

Install a Topaz toolchain that provides the topaz lsp command. The extension does not include a compiler. If topaz is not on PATH, set topaz.executablePath to the executable.

If the executable cannot be found, the extension reports the problem and keeps its static editor support available.

Compiler selection

topaz.compiler has three choices.

default follows the compiler policy of the installed Topaz product.
rust selects the Rust Stage 0 compiler explicitly for comparison or recovery.
self selects the installed self-hosted compiler explicitly.

The extension reads the selection once when it starts a language-server process. Reload the editor window after changing the compiler or executable setting.

Language server

The installed language server provides diagnostics, hover, definitions, references, rename, symbols, completion, signature help, and quick fixes. The extension forwards those protocol results and does not create its own compiler diagnostics.
