Description

ai@keter% jirb
irb(main):001:0> puts "hello"
hello
=> nil
irb(main):002:0> (Ctrl-Z)
zsh: suspended jirb
ai@keter% fg

irb(main):003:0*

At this point, characters are not being echoed as they are typed at the prompt. They are echoed only after 'Return' is pressed.

Sorry about the title, it's late. It should be "jirb does not echo characters to the terminal after suspend and resume in the shell"

but I can't find a way of changing it.

Well, this is a very unusual one. It appears to be something failing in jline itself (as usual) and now it actually raises an IOException. I'll investigate a bit more.

I filed JRUBY-3384 for the IOException, which appears to affect only OS X. Now I can reproduce your original issue, where resumed jirb does not echo characters.

I committed a fix in r9076 that tells jline to initialize the terminal after each readline, since after a suspend the terminal seems to need to be reinitialized. Since we can't easily detect suspension, initialize after every readline. Probably not fast, but this is for interactive terminals anyway...so who cares?
