    Sequin: a tool for inspecting ANSI sequences programming github.com/charmbracelet
    1. 5

      Looks very nice, I used a similar tool in the past, https://saitoha.github.io/trachet/, which worked really well

      1. 1

        Just tried using it after I ran into a couple of issues with sequin, but trachet is python 2.x only :'(

          damn, the python 2 to 3 curse strikes again!

            What kind of issues did you encounter? We’d love to know so we can fix ’em.

              I think I couldn't get the examples in the docs that show running an application under a pty provided by sequin to work, sequin -- foo would error out about unrecognized commandline arguments or similar. I ended up solving it by running the application I was interested in profiling under socat then piping that output to sequin and for others requiring interactive tty input, using script session.log and reading the recorded session.log with sequin.

              I also wanted to see if trachet would give more specific results for some of the most common and universally supported private mode operations where sequin would just always report Enable private mode "cursor keys" whether I was enabling or disabling any of a myriad of behaviors.
