Interactive mode should have persistent command line history

Please persist the history per project not globally.
IMO that would produce a better user experience.

Hi Konstantinos,

I've started off with the simple implementation first. If I see others asking for history per project, I will most certainly look at implementing this.

Anybody else have this requirement? How would it enhance the user experience?

Just think of stuff like commands you want to call more then once like

• test-app :unit foo.bar.*

Where the package foo.bar is unique to a project and doesn't make sense to another one. If you switch from project to project it just messes up your history and the commands you would want to use specific to a project.

Or for a different more simple example u might be using something like

• create-app foo.bar.Baz

and then later on at some point you might want to continue with something like

• create-app foo.bar.Qux

you could recall the last commands and just change the ending. (As package names are often similar in a project, but not for different projects) etc. etc.

Don't get me wrong I'm happy with the simple implementation already, just thought of making it even more user friendly.

By the way is it possible to implement something like bash's reverse search Ctrl+R in JLine ?

Thanks for the pull request.

Is this broken in 2.2.2? I had to "touch ~/.grails_history" to get it working, so it seems the file is not created properly.
