Subject [jira] [Commented] (CAMEL-4931) Improve column display in camel:route-list and similar Karaf commands
Date Fri, 06 Jul 2012 11:55:34 GMT

    [ https://issues.apache.org/jira/browse/CAMEL-4931?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13407924#comment-13407924
] 

Claus Ibsen commented on CAMEL-4931:
------------------------------------

Reuben, I have applied your 1st patch. Maybe you want to work on the other Camel Karaf commands,
and maybe refactor the compute column length logic into a util class to be reused among the
commands.

Then when Karaf has some util JAR we can use, then we can switch to that in the future.

> Camel's shell extensions for Karaf print poorly-formatted results in some cases (particularly
camel:route-list), impeding legibility and ease of use.  It appears that the fields are right-padded
with spaces to 18 columns regardless of maximum actual column length.  
> I understand there's ultimately a limit to the width of the console.  However, if the
width of the console can be determined, it should be filled appropriately; middle truncation
might be an option for excessively long fields (e.g.: "thisIsAVeryLongField...ThatHadToBePartiallyTruncated").
 
> If the console width cannot be determined, it may still be acceptable to scan for the
longest field and set the entire column to its width in the interest of uniform appearance.
