Re: Interactive commands in the Karaf shell

No, the getKeyboard() gives you the InputStream, so, you read from there 
directly in the command.

Hi Damien,

mask defines if you want the output or not, and the kind of output (*, '

readLine() is fine if you just want a single line typed by the users.
getKeyboard() gives your the full keyboard input (multiline, including
breaking characters), it's what I'm using in the vi/edit command.

Hi Patrique,

I have been able to achieve it using session.readLine() :
final String userInput = session.readLine("Do you want to proceed with

the

deletion? (y/n)\n", null);
if (!StringUtils.equalsIgnoreCase(userInput, "y")) return;

I don't know what the "mask" parameter is for, but just setting it to

null

did the job.

I assume that session.getKeyboard() is useful when you want to listen the
keyboard while the command is running, whereas with readLine() it pauses
the execution and waits for the input.

Hi Damien,

Yes, sure.

You can get the session by reference (for instance @Reference Session).

Then session gives you access to getKeyboard() which is a input stream
with what the user input.

I can improve the example with the required code if you want.

Re: Pax Web 8.0.0 is just one click away

[Jean-Baptiste Onofré]

Hi Greg,

thanks for the update !

I'm ready to push the change on Karaf to "promote" main as 4.4.0 and 
have karaf-4.3.x.


Just waiting for Pax Web 8.0.0 to directly update and trigger a build on 
Jenkins ;)


Regards
JB

Hello!

I've just prepared Pax Web 8.0.0 release and the staging repository URL 
is https://oss.sonatype.org/content/repositories/orgops4j-1524/ 



How to test it in Karaf? Start fresh (with Karaf 4.3.3 for example), 
uncomment "karaf" user in etc/users.properties and:


|karaf@root()> repo-remove 
mvn:org.ops4j.pax.web/pax-web-features/7.3.19/xml/features karaf@root()> 
feature:install maven karaf@root()> maven:repository-add -id pax-web-8 
https://oss.sonatype.org/content/repositories/orgops4j-1524/ 
 
karaf@root()> repo-add 
mvn:org.ops4j.pax.web/pax-web-features/8.0.0/xml/features karaf@root()> 
feature:install pax-web-http-jetty pax-web-war karaf@root()> 
bundle:install -s 
'webbundle:mvn:io.hawt/hawtio-war/2.13.6/war?Web-ContextPath=/hawtio' |



Now you can navigate to http://localhost:8181/hawtio 
 and see for example:

Now, I can click "Release" button any time soon and Pax Web 8 will be 
available in Maven Central. I just hope for a little feedback about the 
above steps ;)


kind regards
