[jira] [Commented] (GROOVY-6453) groovysh in Windows 7/8/10 doesn't support arrow keys and Del
[ https://issues.apache.org/jira/browse/GROOVY-6453?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=1760#comment-1760 ] 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\\.groovy, and it still didn't work. > groovysh in Windows 7/8/10 doesn't support arrow keys and Del > - > > Key: GROOVY-6453 > URL: https://issues.apache.org/jira/browse/GROOVY-6453 > Project: Groovy > 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 (!) >Reporter: Andrew P Fink >Priority: Major > Labels: console, jline > > I have bare windows 8 with fresh JDK.

You can add the following code to your groovy.rc as a workaround:
{noformat}
@groovy.transform.InheritConstructors
class WindowsTerminalControlCharFix extends jline.WindowsTerminal {
@Override
protected boolean isSystemIn(java.io.InputStream i) throws IOException {
// groovysh wraps the input stream in
WrappedInputStream, need to handle this case properly to enable windows
controll character handling
if (i instanceof
org.codehaus.groovy.tools.shell.util.WrappedInputStream) {
return
super.isSystemIn(((org.codehaus.groovy.tools.shell.util.WrappedInputStream)i).wrapped);
}
return super.isSystemIn(i);
}
}
// if no terminal specified use a version of windows terminal class that
handles windows control characters properly - see
https://issues.apache.org/jira/browse/GROOVY-6453
if (!System.getProperty("jline.terminal")) {
jline.TerminalFactory.registerFlavor(jline.TerminalFactory.Flavor.WINDOWS,
WindowsTerminalControlCharFix.class);
System.setProperty("jline.terminal","win");
}

> 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)
