Open Files for Visual Studio Code (Beta)

One day I got tired of dealing with the mess that is the Open Editors widget in vscode, so I decided to do something about it. The result is this extension, which is really the same thing as Open Editors with the addition of sorted and grouped files.

Known Issues

• Vscode does not have any API's to retrieve open editors, instead this addon uses a hack which isn't always reliable
  • This hack requires that it cycles through all open files when you start vscode, which isn't very reliable either but it's better than not seeing any files
  • There is a refresh option (under the widget navbar) to manually refresh the list of open files. Otherwise just switching to a file will make it appear.
  • This cannot be solved by this addon. The vscode devs have to add new API's to address this. Please add your +1 here: https://github.com/Microsoft/vscode/issues/15178
• Splits are not tracked very well, or in some cases at all. This is a limitation in the vscode extension API, I have yet to find a workaround.

Missing API's and Workarounds

• No API to retrieve a list of open editors
  • Workaround:
    • On startup cycle through all open tabs (which is error-prone) and capture their "onDidChangeActiveTextEditor" event
    • While working capture onDidChangeActiveTextEditor and onDidCloseTextDocument events to build the list of open editors
  • Bug (please +1): https://github.com/Microsoft/vscode/issues/15178
• No "Opened Editor" or "Closed Editor" event (a text document is not an editor, they are constantly "opened" and "closed" as you switch tab without actually closing the tab itself)
  • Workaround:
    • When switching tabs the onDidChangeActiveTextEditor event is called before onDidCloseTextDocument. When closing a tab it's the inverse. Use this information to infer whether a tab was closed or just switched.
