|
|||
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.
