Bluepill

Have an app that's letting you down? Keep it up!

What is this?

Do you have an app that needs to run continuously in the terminal or in the background, but crashes once in a while? Bluepill can help you keep it up and running!

You just need to run bluepill your_app_executable arg1 arg2 etc and it will relaunch the app with the same arguments every time it crashes.

Features

• Hooks up stdin/stdout/stderr so that your app can still receive keyboard input and print to the terminal.
• Restarts your app every time it exits in error, but will exit if the app finishes successfully.
• Will honor Ctrl+C and SIGTERM, although it won't pass these on to the app (see the TODO section).

Install

Just download the latest release from the releases page, put the executable in your $PATH and start using it.

Build

go build

TODO

• Pass received signals to the app. This should help with graceful handling of Ctrl+C, or system shutdown (as well as apps that make use of other signals).
• Multi-arch builds
• Command line arguments to:
  • Allow restarting apps that exit without any error
  • Disabling grace period
  • Setting a custom grace period

FAQ

What's with the name?

I feel pretty cozy here in the matrix even if it's fake.

Do you really need a FAQ for such a small piece of software?

No, but I like FAQs.

Are there any useful questions or answers in the FAQ?

None at all.
