Getting the currently open file in VSCode

Question

Is there a command in the vscode namespace that allows you to get the TextDocument instance for the currently open file? I found vscode.workspace.onDidOpenTextDocument, but it doesn't work for files that are open on launch

Answer 1

A few options depending on your needs:

// Single active editor. Editors have a `.document` property
vscode.window.activeTextEditor

// All showing text editors. For a split view, there are two active editors 
vscode.window.visibleTextEditors

// All open documents that vscode knows about. Do not have to be showing
vscode.workspace.textDocuments
