问题
I am using Java 8 build 1.8.0-b132 on OSX 10.9.2.
I am playing with Nashorn the new JavaScript runtime in Java 8.
I am using Library/Java/JavaVirtualMachines/jdk1.8.0.jdk/Contents/Home/bin/jjs
but unfortunately jjs
is pretty unusable in interactive mode since cursor left/right does not work:
jjs
jjs> var x =^[[D
The above output (^[[D) is the result of pressing 'cursor left'. Is there a way to fix that behavior and using cursor left/right in the jjs console?
回答1:
Thanks to @assylias for pointing me to rlwrap.
I installed rlwrap via homebrew:
brew install rlwrap
Then I defined an alias in my .zshrc (would be the same for bash in .bashrc)
alias jjs='rlwrap /Library/Java/JavaVirtualMachines/jdk1.8.0.jdk/Contents/Home/bin/jjs'
Now I can use jjs
on the commandline and the <- and -> keys are working as expected.
