Question

When I run jdb in bash the arrow keys produce weird garbage:

up: ^[[A
down: ^[[B
left: ^[[D
right: ^[[C

So I can’t use the command history, or correct a spelling mistake, because I can’t navigate the text at all, which is very annoying. Is there a solution to this?

Java version info:

"1.6.0_24"                                                                             
OpenJDK Runtime Environment (IcedTea6 1.11.5) (fedora-68.1.11.5.fc16-x86_64)                        
OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)

Bash version info:

GNU bash, version 4.2.28(1)-release (x86_64-redhat-linux-gnu)

Answer 1

Have you tried running JLine with JDB ?

Can I use JLine as the input handler for jdb (the java debugger)?

Yes. Try running:

java jline.ConsoleRunner com.sun.tools.example.debug.tty.TTY args

JLine gives you cursor interaction and command line history.
