Zero Install

Copyright Thomas Leonard, 2010


The 0launch command can be used to run a program, by giving it the program's
full name (a web address or "URL"). It does not need to be installed or run as
root. It does not write to any shared directories (like /usr/bin or /usr/lib).
It stores downloads in a cache directory so that you don't need to download
anything twice, and programs can still be used when you are off-line.

A complete program is made up of many different components, typically written
by different groups of people. Each component is available in multiple
versions. 0launch is used when starting a program. Its job is to decide
which implementation of each required component to use.

An interface describes what a component does. Zero Install starts with the
interface for the program you want to run (like 'The Gimp') and chooses an
implementation (like 'The Gimp 2.2.0'). However, this implementation will in
turn depend on other interfaces, such as 'GTK' (which draws the menus and
buttons). Thus, Zero Install must choose implementations of each dependancy
(each of which may require further interfaces, and so on).

See for details.


Zero Install uses the normal Python distutils method of installation. To
install system-wide, run like this:

  $ sudo python install

You can also install just to your home directory (this doesn't require root

  $ python install --home ~ --install-data ~/.local
  $ export PATH=$HOME/bin:$PATH

Logging out and back in again will ensure $PATH and the Applications menu get
updated correctly, on Ubuntu at least.


To run a program by its URI:

  $ 0launch

To create a short-cut:

  $ 0alias rox-edit

For more information, see the man-pages for 0launch, 0alias and 0store.
