For quite some time I didn’t understand why the console in sbt, the scala built tool, is using up arrow for activating reverse-i-search (normally used in terminal with keyboard shortcut CTRL+R). This was one of those small bugs that are not annoying enough for you start searching for a solution straight away. After some time I got fed up and did some googling. Turns out it is not a bug within sbt, but a common side-effect caused by
Some time ago I had configured a sweet bash productivity feature that completes partial commands from history with the up arrow. I wrote about this and other bash productivity tips a few weeks ago.
Luckily this feature can be kept in bash, but disabled everywhere else. The inputrc fix provided was originally posted by Paul Phillips on sbt google group. Just wrap the conflicting part of inputrc with a simple conditional.
Best of both worlds. Up arrow still works its magic in bash and the standard way in sbt console. Also CTRL-R can be used for history searching in sbt.
