need some help to find the docs/howto’s on below, 1. log the console output to a file on disk directly from a HLA? 2. are the HLA python scripts sandboxed somehow or could they expose a socket for remote control? 3. can a HLA trigger a capture to be saved to disk? ---

@janny-bb Thanks for writing in! My responses to your questions are below. > 1. log the console output to a file on disk directly from a HLA? We’re currently tracking this feature request below, and I added a comment/vote for you so we can track your need for this. We unfortunately don’t have a way of automating this. Right now, you can manually copy text from the terminal (e.g. Ctrl+C on Windows) and paste it elsewhere, but I understand that this is probably not what you require. > **[Stream Terminal Output to File - Logic 2 - Ideas and Feature Requests - Saleae](https://ideas.saleae.com/b/feature-requests/stream-terminal-output-to-file/)** > > It would be nice to add an option to stream or save terminal output to a file, such as a .txt file > 1. are the HLA python scripts sandboxed somehow or could they expose a socket for remote control? Currently, extensions are not sandboxed. You can read more information about this below. Hopefully that forum thread answers your question! > [@Logic2 security posture](https://discuss.saleae.com/t/logic2-security-posture/603): > > My impression based on the developer docs and posts like [Third party libraries with HLAs](https://discuss.saleae.com/t/third-party-libraries-with-hlas/595/2) is that the Logic2 app does no [sandboxing](https://doc.pypy.org/en/latest/sandbox.html) of its Python extensions — is that a correct understanding? And based on download size and mention of WebGL my impression is that the app is now Electron-based. If that’s a correct assumption, can you speak to what plans Saleae has for ensuring that its own bundling of third-party JS libraries as well as the Python code run through the marketplace don’t negatively i… > 1. can a HLA trigger a capture to be saved to disk? Apologies this is also not possible at the moment! HLAs do have the ability to trigger on data in real-time. You can read more about this below (section titled “Trigger View - Triggering on a Protocol Result”). However, it doesn’t have the ability to subsequently save the capture to disk. > **[Capture Modes](https://support.saleae.com/user-guide/using-logic/capture-modes)** I think the most similar feature request might be below.

By the way, we’d love to know more about your testing workflow, as well as what kind of data you are interested in capturing exactly!
