Is it possible to call commands between extensions in VSCode? - visual-studio-code

Question

For example, there are two VSCode extensions:
extension1 has registered command exCommand1
extension2 has registered command exCommand2
According to documentation, a VSCode extension can call commands
(ref: https://code.visualstudio.com/docs/extensionAPI/vscode-api)
executeCommand<T>(command: string, ...rest: any[]): Thenable<T | undefined>
If API Doc is correct then
extension1 can call exCommand2 provided by extension2
extension2 can call exCommand1 provided by extension1
But, VSCode's extensions are lazily loaded, so how does one call a command from another extension that may not already be loaded?

I know this is an old post, if you still have the same requirement or for others googling, this is how I have done it.
var xmlExtension = vscode.extensions.getExtension( 'DotJoshJohnson.xml' );
// is the ext loaded and ready?
if( xmlExtension.isActive == false ){
xmlExtension.activate().then(
function(){
console.log( "Extension activated");
// comment next line out for release
findCommand();
vscode.commands.executeCommand("xmlTools.formatAsXml");
},
function(){
console.log( "Extension activation failed");
}
);
} else {
vscode.commands.executeCommand("xmlTools.formatAsXml");
}
// dev helper function to dump all the command identifiers to the console
// helps if you cannot find the command id on github.
var findCommand = function(){
vscode.commands.getCommands(true).then(
function(cmds){
console.log("fulfilled");
console.log(cmd);
},
function() {
console.log("failed");
console.log(arguments);
}
)
};
