What can I use for a simple IPC between Go and a program written in arbitrary lang ?

I&#39;m quite keen on line-based IPC if the processes are all under your own development/control and are all &#34;reasonably fast&#34; with regards to eg. JSON. I struggle to find a better protocol for line-based text-based IPC ---custom stuff always seems to end up growing to the point where switching to JSON is the sane choice--- and I like line-based-text-based because one can pose as the-other-process interactively via the terminal when it becomes necessary for a bit. Also it&#39;s handy to have the 2 output channels built-in to every process, for example &#34;stdout for IPC, stderr for debug-logging to the other side&#34;.</p> <p>Performance-wise seems fine if the processes are &#34;ping-ponging structured messages&#34; between each other, rather than say continuously-streaming (where raw-bytes serializing might prove more efficient).</p></pre>
