This extension allows you to remotely control instances of Visual Studio Code by exposing a REST endpoint that you can use to invoke vscode commands. In the background it launches a HTTP server that listen on the localhost
interface for requests of commands to execute.
The demo below shows how we can open a terminal, run some commands in it, then close all terminals, open a file with the cursor in a specified location and finally start a debug session on the same file that is orchestrating it all!
DISCLAIMER: This extension was forked from Remote Control.
The main motivation behind it was that while Remote Control
uses websockets
, for my use case I can only rely on HTTP REST calls. In addition, some commands I need to use require non-primitive JavaScript types which are not handled except for a couple of cases in the original extension (e.g. the Uri
for vscode.open
command).
Extension Settings
The extension has the following settings which you can use to configure it:
restRemoteControl.enable
: enable/disable this extension
restRemoteControl.port
: set the port number on which the HTTP server will listen, otherwise the extension will pick one available port for you based on the current workspace path.
restRemoteControl.fallbacks
: an array of port numbers to fallback to if the port is already in use.
Usage
When you install this extension, it will automatically try to start a HTTP server. The port can be specified with VSCode setting restRemoteControl.port
. When you are going to use multiple VSCode sessions at the same time, it is best to configure it at workspace level or use the restRemoteControl.fallbacks
setting to specify fallback ports when the specified one is already in use. VSCode terminals opened will have environment variable REMOTE_CONTROL_PORT
set with the port the server is currently listening on.
Once installed, you can execute vscode commands
by making HTTP requests. The HTTP verb is currently ignored. Here are few examples using curl
, assuming VSCode is listening on port 37100
:
# Create a new terminal
curl http://localhost:37100 -d '{"command":"workbench.action.terminal.new"}'
# or curl http://localhost:37100/?command=workbench.action.terminal.new
# Run `pwd` in the currently active terminal
curl http://localhost:37100 -d '{"command":"custom.runInTerminal", "args": ["pwd"]}'
# or curl http://localhost:37100/?command=custom.runInTerminal&args=%5B%22pwd%22%5D
# Kill all terminals
curl http://localhost:37100 -d '{"command":"workbench.action.terminal.killAll"}'
# or curl http://localhost:37100/?command=workbench.action.terminal.killAll
All requests are expected to be in a JSON HTTP request body in the form:
{
"command": "<command-id>",
"args": ["<arg1>", "<arg2>", "...", "<argN>"]
}
or URL encoded as ?command=<command-id>&args=<url-encoded-of-json-string-of-args>
.
Some VSCode commands expect VSCode's defined types such as Range, Uri, Position and Location. To accommodate for those, such arguments can be passed as a special types, see the example below which effectively invokes editor.action.goToLocations
with Uri
, Position
and an array of Location
s:
{
"command": "editor.action.goToLocations",
"args": [
{
"__type__": "Uri",
"args": ["/path/to/file.py"]
},
{
"__type__": "Position",
"args": [4, 0]
},
[
{
"__type__": "Location",
"args": [
{
"__type__": "Uri",
"args": ["/path/to/file.py"]
},
{
"__type__": "Position",
"args": [11, 5]
}
]
}
]
]
}
Custom defined commands:
As the extension progresses, I plan to add more special commands (i.e. commands that require some use of the VSCode API). For now, we have defined the following commands:
custom.goToFileLineCharacter
: allows you to navigate to a specific position in a file by passing the file path, line and column number as arguments
custom.startDebugSession
: allows you to invoke vscode.debug.startDebugging()
API by passing the workspace folder and a name or definition of a debug configuration as it would be set in launch.json
custom.runInTerminal
: allows you to invoke commands the currently active integrated terminal
custom.showQuickPick
: show quick pick dialog to collect selection from the user
custom.showInputBox
: show input box dialog to collect a input string from the user
custom.showInformationMessage
, custom.showWarningMessage
and custom.showErrorMessage
: show message dialogs to the user and let them click on a button
custom.listInstalledExtensions
: get the list of installed extension IDs
custom.getExtensionInfo
: get details of an installed extension by passing the extension ID
To implement in the near future:
- Add the ability to set a breakpoint at the specified file/line combination
How do I get the command ID?
To get the command ID, open the Command Palette
and type Show all commands
. This will give you a list with all the available commands. VScode's built-in commands can be found here.
Behind each command, there is a gear button. When you click on it, it brings you to the shortcut configuration. Where you can right-click on the command and copy its ID.
