OK,
so besides fixing the problem with the real multi-mode command (I had to
introduce remote session handling - feels quite awful), I also embedded
jline classes (
https://github.com/jline/jline2) inside the local command
HK2-Jar to support some features I always wanted to work on inside asadmin:
* command completion (still static for now and very basic)
* command history
* user shell behavior (e.g. CTRL + ALT + BACK_SPACE deletes a word)
* no more weird control characters printed on the terminal
* no additional new-lines
So now this works:
gogo$ x=y
gogo$ echo $x
y
gogo$
I did a first release for this (as it also requires an updated felix
remote command):
Local:
https://oss.sonatype.org/content/repositories/releases/org/ancoron/glassfish/asadmin/org.ancoron.glassfish.asadmin.felix.shell.interactive/1.0.6/org.ancoron.glassfish.asadmin.felix.shell.interactive-1.0.6.jar
Remote:
https://oss.sonatype.org/content/repositories/releases/org/ancoron/glassfish/asadmin/org.ancoron.glassfish.asadmin.felix.shell/1.0.6/org.ancoron.glassfish.asadmin.felix.shell-1.0.6.jar
However, for the pure felix shell there are no sessions available and so
sessions are only supported for gogo.
What do you think?
Cheers,
Ancoron
