Apache Felix Gogo

Apache Felix Gogo is a subproject of Apache Felix implementing a command line shell for OSGi. It is used in many OSGi runtimes and servers (Felix distro, Eclipse IDE, Apache Karaf, ...).

Overview

The Gogo subproject consists of three bundles:

Working with the sources

You can find the sources on apache svn there is also a mirror at github.

Clone git clone https://github.com/apache/felix

Using Gogo with the Felix Framework

Gogo is included as the default shell in the felix framework distribution. To use it, you just start the framework like normal:

$ java -jar bin/felix.jar

Changing shell colors

The colors of the command shell cane be adjusted by setting a property in an init script or directly on the shell.

HIGHLIGHTER_COLORS = "rs=35:st=32:nu=32:co=32:va=36:vn=36:fu=94:bf=91:re=90"

The property above forms a map from highlight type to ANSI color code.

These are the highlight types

The colors of the ls output can be adjusted using

LS_COLORS = "dr=1;91:ex=1;92:sl=1;96:ot=34;43"

The color types are these:

Last but not least grep can also be adjusted

GREP_COLORS = "mt=1;31:fn=35:ln=32:se=36"

Types:

Origin in RFC 147

Gogo is based on the OSGi RFC 147, which describes a standard shell for OSGi-based environments. See RFC 147 Overview for more information. Unfortunately this RFC was never made a standard.
