bzr bash-completion plugin

==========================

This plugin generates a shell function which can be used by bash to

automatically complete the currently typed command when the user

presses the completion key (usually tab).

It is intended as a bzr plugin, but can be used to some extend as a

standalone python script as well.

-------------------------------

Bundled and standalone versions

-------------------------------

This plugin has been merged_ into the main source tree of Bazaar.

Starting with the bzr 2.3 series, a common bzr installation will

include this plugin.

There is still a standalone version available. It makes the plugin

available for users of older bzr versions. When using both versions,

local configuration might determine which version actually gets used,

and some installations might even overwrite one another, so don't use

the standalone version if you have the bundled one, unless you know

what you are doing. Some effort will be made to keep the two versions

reasonably in sync for some time yet.

This text here documents the bundled version.

Using

-----

Using as a plugin

-----------------

This is the preferred method of generating the completion function, as

it will ensure proper bzr initialization.

::

  eval "`bzr bash-completion`"

Lazy initialization

-------------------

Running the above command automatically from your ``~/.bashrc`` file

or similar can cause annoying delays in the startup of your shell.

To avoid this problem, you can delay the generation of the completion

function until you actually need it.

To do so, source the file ``contrib/bash/bzr`` shipped with the bzr

source distribution from your ``~/.bashrc`` file

or add it to your ``~/.bash_completion`` if

your setup uses such a file. On a system-wide installation, the

directory ``/usr/share/bash-completion/`` might contain such bash

completion scripts.

Note that the full completion function is generated only once per

shell session. If you update your bzr installation or change the set

of installed plugins, then you might wish to regenerate the completion

function manually as described above in order for completion to take

these changes into account.

--------------

Design concept

--------------

The plugin is designed to generate a completion function

containing all the required information about the possible

completions. This is usually only done once when bash

initializes. After that, no more invocations of bzr are required. This

makes the function much faster than a possible implementation talking

to bzr for each and every completion. On the other hand, this has the

effect that updates to bzr or its plugins won't show up in the

completions immediately, but only after the completion function has

been regenerated.

-------

License

-------

As this is built upon a bash completion script originally included in

the bzr source tree, and as the bzr sources are covered by the GPL 2,

this plugin here is licensed under these same terms.

If you require a more liberal license, you'll have to contact all

those who contributed code to this plugin, be it for bash or for

python.

-------

History

-------

The plugin was created by Martin von Gagern in 2009, building on a

static completion function of very limited scope distributed together

with bzr.

A version of it was merged into the bzr source tree in May 2010.
