Bazaar is a distributed version control system that makes it easier for
9
people to work together on software projects.
11
Over the next five minutes, you'll learn how to put your files under
12
version control, how to record changes to them, examine your work, publish
13
it and send your work for merger into a project's trunk.
15
If you'd prefer a more detailed introduction, take a look at
10
This is a very brief 5-minute tutorial, covering only what a first time user
11
needs to start a project or start contributing to a project using Bazaar.
12
For a more detailed look, see `Learning More`_.
22
This guide doesn't describe how to install Bazaar but it's usually very
23
easy. You can find installation instructions at:
25
- **GNU/Linux:** Bazaar is probably in your GNU/Linux distribution already.
26
- **Windows:** `installation instructions for Windows`_.
27
- **Mac OS X:** `installation instructions for Mac OS X`_.
29
For other platforms and to install from source code, see the Download_
30
and Installation_ pages.

18
See http://bazaar-vcs.org/Download. Bazaar is probably in your GNU/Linux
19
distribution already. If not, it's trivial to install on any platform that
20
runs Python 2.4, including Windows. Installation should take at most a few

25
====================
41
Before you start working, it is good to tell Bazaar who you are. That
42
way your work is properly identified in revision logs.
44
Using your name and email address, instead of John Doe's, type::
46
$ bzr whoami "John Doe <john.doe@gmail.com>"
48
Bazaar will now create or modify a configuration file, including your
49
name and email address.
51
Now, check that your name and email address are correctly registered::
27
You want Bazaar to correctly identify you in revision logs. Using your name
28
and email instead of Joe Doe's, type::
30
$ bzr whoami "Joe Doe <joe.doe@gmail.com>"
54
John Doe <john.doe@gmail.com>
57
Putting files under version control
58
===================================
60
Let's create a directory and some files to use with Bazaar::
65
$ touch test1.txt test2.txt test3.txt subdirectory/test4.txt
67
**Note for Windows users:** use Windows Explorer to create your
68
directories, then right-click in those directories and select
69
``New file`` to create your files.
71
Now get Bazaar to initialize itself in your project directory::
75
If it looks like nothing happened, don't worry. Bazaar has created a
76
branch_ where it will store your files and their revision histories.
78
.. _branch: http://bazaar-vcs.org/Branch
80
The next step is to tell Bazaar which files you want to track. Running
81
``bzr add`` will recursively add everything in the project::
88
added subdirectory/test4.txt
90
Next, take a snapshot of your files by committing them to your branch. Add
91
a message to explain why you made the commit::
35
Joe Doe <joe.doe@gmail.com>
38
Putting Existing Files Under Version Control
39
============================================
41
It is very easy to put an existing set of files under version control using
93
47
$ bzr commit -m "Initial import"
95
As Bazaar is a distributed version control system, it doesn't need to
96
connect to a central server to make the commit. Instead, Bazaar stores your
97
branch and all its commits inside the directory you're working with; look
98
for the ``.bzr`` sub-directory.
101
Making changes to your files
102
============================
104
Let's change a file and commit that change to your branch.
106
Edit ``test1.txt`` in your favourite editor, then check what have you done::
109
=== modified file 'test1.txt'
110
--- test1.txt 2007-10-08 17:56:14 +0000
111
+++ test1.txt 2007-10-08 17:46:22 +0000
115
Commit your work to the Bazaar branch::
117
$ bzr commit -m "Added first line of text"
49
You can now make changes, track them, publish your branch and so on as
53
Creating A Personal Branch
54
==========================
56
Rather than starting a new project, you may wish to work on an existing
57
project either you or someone else has published.
59
Create a branch of an existing project::
61
$ bzr branch http://example.com/code/foobar.dev foobar.joe
62
Branched 1 revision(s).
64
Note that after you create a personal branch, you don't need web access to
76
Check what have you done::
79
=== modified file 'foo.c'
88
_pyfribidi_log2vis (PyObject * self, PyObject * args, PyObject * kw)
91
Commit your hard work::
93
$ bzr commit -m 'added some whitespace'
118
94
Committed revision 2.

143
Publishing your branch with sftp
144
================================
146
There are a couple of ways to publish your branch. If you already have
147
an SFTP server or are comfortable setting one up, you can publish your
150
Otherwise, skip to the next section to publish with Launchpad_, a free
151
hosting service for Bazaar.
153
.. _Launchpad: https://launchpad.net/
155
Let's assume you want to publish your branch at ``www.example.com/myproject``::
157
$ bzr push --create-prefix sftp://your.name@example.com/~/public_html/myproject
158
2 revision(s) pushed.
160
Bazaar will create a ``myproject`` directory on the remote server and
161
push your branch to it.
163
Now anyone can create their own copy of your branch by typing::
165
$ bzr branch http://www.example.com/myproject
167
**Note:** to use sftp, you may need to install ``paramiko`` and
168
``pyCrypto``. See http://bazaar-vcs.org/InstallationFaq for details.
171
Publishing your branch with Launchpad
172
=====================================
174
Launchpad is a suite of development and hosting tools for free
175
software projects. You can use it to publish your branch.
177
If you don't have a Launchpad account, follow the `account signup guide`_
178
and `register an SSH key`_ in your new Launchpad account.
180
.. _account signup guide: https://help.launchpad.net/CreatingYourLaunchpadAccount
181
.. _register an SSH key: https://launchpad.net/people/+me/+editsshkeys
183
Replacing ``john.doe`` with your own Launchpad username, type [#]_::
185
$ bzr push lp:~john.doe/+junk/myproject
187
.. [#] Use of the ``lp:`` URL scheme requires bzr 0.92 or later.
189
**Note:** ``+junk`` means that this branch isn't associated with any particular
190
project in Launchpad.
192
Now, anyone can create their own copy of your branch by typing::
194
$ bzr branch lp:~john.doe/+junk/myproject
196
You can also see information about your branch, including its revision
197
history, at https://code.launchpad.net/people/+me/+junk/myproject
200
Creating your own copy of another branch
201
========================================
203
To work with someone else's code, you can make your own copy of their
204
branch. Let's take a real-world example, Bazaar's GTK interface::
206
$ bzr branch lp:~bzr/bzr-gtk/trunk bzr-gtk.john
207
Branched 292 revision(s).
209
Bazaar will download all the files and complete revision history from the
210
bzr-gtk project's trunk branch and create a copy called bzr-gtk.john.
212
Now, you have your own copy of the branch and can commit changes with
213
or without a net connection. You can share your branch at any time by
214
publishing it and, if the bzr-gtk team want to use your work, Bazaar
215
makes it easy for them to merge your branch back into their trunk branch.
218
Updating your branch from the main branch
119
Updating Your Branch from the Main Branch
219
120
=========================================
221
While you commit changes to your branch, it's likely that other people will
222
also continue to commit code to the parent branch.
224
To make sure your branch stays up to date, you should merge changes from
225
the parent into your personal branch::
122
While you work hard on your branch, others may have committed new code to the
123
main branch. From time to time, you want to merge changes from the main
124
branch into your branch::
228
Merging from saved parent location: http://bazaar.launchpad.net/~bzr/bzr-gtk/trunk
127
Using saved location: http://example.com/code/foobar.dev
229
128
All changes applied successfully.
130
What was changed locally by merging the main branch?
231
Check what has changed::
235
If you're happy with the changes, you can commit them to your personal
238
$ bzr commit -m "Merge from main branch"
239
Committed revision 295.
242
Merging your work into the parent branch
243
========================================
245
After you've worked on your personal branch of bzr-gtk, you may want to
246
send your changes back upstream to the project. The easiest way is to
247
use a merge directive.
249
A merge directive is a machine-readable request to perform a
250
particular merge. It usually contains a patch preview of the merge
251
and either contains the necessary revisions, or provides a branch
252
where they can be found.
254
Replacing ``mycode.patch``, create your merge directive::
256
$ bzr send -o mycode.patch
257
Using saved parent location: http://bazaar.launchpad.net/~bzr/bzr-gtk/trunk
259
You can now email the merge directive to the bzr-gtk project who, if
260
they choose, can use it merge your work back into the parent branch.
135
=== modified file 'pyfribidi.c'
146
Commit the changes from the main branch::
148
$ bzr commit -m 'merge from main branch'
149
Committed revision 6.
151
Note that you may occasionally need to resolve conflicts or make other minor
152
changes (so tests pass say) before committing. For these reasons, merge does
153
not implicitly commit.
156
Publishing Your Branch
157
======================
159
You can simply use rsync to copy your branch to a web server, but using
160
``bzr push`` is the easiest way. Let's assume you want to publish your
161
branch in jod.example.com/foobar.joe and you have sftp access to the server::
163
$ bzr push sftp://jod@jod.example.com/public_html/foobar.joe/
164
2 revision(s) pushed.
166
Note that to use sftp, your may need to install ''paramiko'' and ''pyCrypto''.
167
See http://bazaar-vcs.org/InstallationFaq for details.
169
Now anyone can get your branch with (try it yourself!)::
171
bzr branch http://jod.example.com/foobar.joe/
