@ -14,3 +14,21 @@ integrated into the command line and can be started via the `lsp` sub-command.
When the language server is started, a `LanguageServer` instance is created
which holds all of the state of the language server. It also defines all of the
methods that the client calls via the Language Server RPC protocol.
## Custom requests
The LSP currently supports the following custom requests. A client should
implement these in order to have a fully functioning client that integrates well
with Deno:
- `deno/cache` - This command will instruct Deno to attempt to cache a module
and all of its dependencies. It expects an argument of
`{ textDocument: TextDocumentIdentifier }` to be passed.
- `deno/performance` - Requests the return of the timing averages for the
internal instrumentation of Deno.
- `deno/virtualTextDocument` - Requests a virtual text document from the LSP,
which is a read only document that can be displayed in the client. This allows
clients to access documents in the Deno cache, like remote modules and
TypeScript library files built into Deno. It also supports a special URL of
`deno:/status.md` which provides a markdown formatted text document that
contains details about the status of the LSP for display to a user.
