[jira] [Commented] (GROOVY-6453) groovysh in Windows 7/8/10 doesn't support arrow keys and Del

["Guy Rouillier (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GROOVY-6453?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16666760#comment-16666760 ] 

Guy Rouillier commented on GROOVY-6453:
---------------------------------------

Found this via search.  I'm on Windows 7 64-bit, and tried both groovy-2.6.0-alpha-3 and groovy-3.0.0-alpha-3.  Cursor keys are not working in either one.  I'm surprised to see this issue is now 5 years old.  Is there some basic restriction preventing this from being corrected in groovysh?

I tried creating a groovy.rc file containing the contents from the previous post by Dariusz Antoniuk, but don't know where to put it.  I tried in \groovy-3.0.0-alpha-3\bin, \groovy-3.0.0-alpha-3\conf, and C:\Users\<myusername>\.groovy, and it still didn't work.

>          Issue Type: Bug
>          Components: Groovysh
>    Affects Versions: 2.2.0
>         Environment: Windows 8, 64bit (v6.2, build 9200), java version "1.7.0_45" SE Runtime Environment (build 1.7.0_45-b18) HotSpot 64-Bit Server VM (build 24.45-b08, mixed mode), Russian locale (!)

> I have bare windows 8 with fresh JDK. I run Groovysh in cmd.exe.
> Groovysh 2.1.9 works as expected.
> Groovysh 2.2.0 doesn't react to arrow keys and Del, i.e. up key doesn't show previous command, left key doesn't shift cursor etc.
> After some investigation I found what is working:
> ctrl-a   go to beginning of line
> ctrl-e   go to End of line
> ctrl-f   go Forward one char
> ctrl-b   go Backward one char
> ctrl-d   delete the char
> ctrl-h   and backspace = delete left char
> ctrl-p   recall previous line
> ctrl-n   recall next line
> ctrl-s   search
> ctrl-r   reverse search 
> It's nice and feel myself like a Linux hacker, but I want arrow keys too ;-)
> I tried different options:
> - upgrade jline2.10 to 2.11 - no effect
> - --terminal=unix - it helps, but duplicate prompt (groovy:000>) and no more colors in console 
> Looks like problem lies in new jline v2 (groovysh 2.1.9 uses jline1.0)
