Ask HN: Writing a Shell in Go, Advice

4 pointshello_computer2 comments

I like Go, and I'm thinking about writing a shell in it, but I'm not sure how well Go's runtime will play with fork and exec (probably not well). Any advice?

Take a look at yaegi, it already can be used and embedded as a REPL and shell. [1]

I think it does it very well.

Had some recent experience trying to write a shell and have it exposed over the web using websockets.

There are some parts where you wish it behaved like C but it does the job and is more than sufficient for a shell.
