feat: Use spans for builtin and declarative macro expansion errors
This should generally improve some error reporting for macro expansion errors. Especially for `compile_error!` within proc-macros
When the user applies the "Extract Variable" assist, the cursor is
positioned at the newly inserted variable. This commit adds a command
to the assist that triggers the rename action in VSCode. This way, the
user can quickly rename the variable after applying the assist.
Fixes part of: #17579
feat: add `toggleLSPLogs` command
Implement client-side command to toggle LSP logs in VSCode.
The command replaces the need to add/remove the `"rust-analyzer.trace.server": "verbose"` setting each time one wants to display logs. I've also updated the docs/ instances that reference the now outdated manual method.
The command labeled `rust-analyzer: Toggle LSP Logs` enables the setting project-wide and opens the relevant trace output channel.
Closes#8233
Displaying local instead of web docs can have many benefits:
- the web version may have different features enabled than locally selected
- the standard library may be a different version than is available online
- the user may not be online and therefore cannot access the web documentation
- the documentation may not be available online at all, for example because it
is for a new feature in a library the user is currently developing
If the documentation is not available locally, the extension still falls back to
the web version.
According to the VS Code documentation, the vscode.open command opens the URL
_in the editor_ (https://code.visualstudio.com/api/references/commands).
However, in reality, it seems to do so only for file:// URLs, falling back to
other applications for other URL schemes (at least for HTTP/HTTPS).
Until now, the URL to the documentation was always HTTP based, so using the
vscode.open command was perfectly fine. However, displaying local documentation
will be supported from now on (see next commit). Local documentation is not
HTTP-based, but instead addressed via a file:// URL. The file URL would
therefore be opened in VS Code instead of in the browser — this is definitely
not what the user wants.
Therefore, the vscode.env.openExternal function is used instead, this function
never opens the URL in VS Code.
