Graceful failure #204

Closed mattjlewis closed 2 years ago

mattjlewis commented 3 years ago

Is it possible for jansi to fail gracefully if the native library fails to load? I.e. ignore any colour output requests and output plain text instead.

Is that related to #207 ?

Yes. I initially removed the call to AnsiConole.systemInstall as I primarily run my apps on Linux which don't need this (AnsiConsole.systemInstall() fails on ARMv6). However, I have recently been running some applications from within my IDE (Eclipse) and was annoyed to see the control characters. I now do this:

        // Attempt to initialise Jansi
        try {
            AnsiConsole.systemInstall();
        } catch (Throwable t) {
            // Ignore
            Logger.trace(t, "Jansi native library not available on this platform: {}", t);
        }

BTW I have setup Docker based compilation for diozero that supports x86, ARMv6, ARMv7 and AArch64 - I basically compile GCC 8 for ARMv6 and use standard tools for the rest. https://github.com/mattjlewis/diozero/tree/main/docker
