Subject [jira] Commented: (KARAF-374) Clean up commands and remove System.out from them, simplify JANSI usage.
Date Tue, 11 Jan 2011 10:57:46 GMT

    [ https://issues.apache.org/jira/browse/KARAF-374?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12980056#action_12980056

Łukasz Dywicki commented on KARAF-374:
--------------------------------------

I just found AnsiRenderer in Jansi. The syntax is following:
@|bold,red Some text|@

@|fg_red,bold Some text on red background|@

> Currently we have two bad things in our commands. First is System.out.println() mix with
getConsole().println()
> Second thing is jansi usage. It is really cool to have colour output under Windows/Unix
shell but printing something with this library is a little hard. Fluent api in this case is
not the best choice:
> String str = Ansi.ansi()
>     .fg(Ansi.Color.RED)
>     .a("Command not found: ")
>     .a(Ansi.Attribute.INTENSITY_BOLD)
>     .a(((CommandNotFoundException) t).getCommand())
>     .a(Ansi.Attribute.INTENSITY_BOLD_OFF)
>     .fg(Ansi.Color.DEFAULT).toString();
> Instead of simple string tags:
> String str = new Ansi("[red]Command not found: [bold]" + ((CommandNotFoundException)
t).getCommand() +  "[/bold][/red]).toString(); 
> These two things are releated because we can simply wrap getConsole().println() with
jansi but System.out.println not.
