). It's acceptable to use
HTML in C calls, especially for bold and emphasis. However, you
should limit the amount of HTML that translators must keep exactly
correct, which means avoid including tags that wrap the entire
translatable string, especially C<< >>.
<&|/l, $button &>Do not click [_1]
# ok
<&|/l, $button &>Do not click [_1]
# not ok
In a few places in RT we also pass HTML as parameters to C
so that translators do not have to reproduce it exactly, and we can
also change it more freely. For example:
<&|/l,
'',
'',
&>Distributed under [_1]version 2 of the GNU GPL[_2].
F looks for C and
C<< <&|/l&>... >> in our source code to pick out translatable
strings, clean them up, and put them into F files. We use
our C<.po> files not only to populate L's lexicons,
but also to sync new translatable strings and translations with
Launchpad. This Launchpad sync is typically done early during the
freeze of RC releases to give our volunteer translators time to
translate all the new strings which, because of the RC freeze, won't
continue changing.
Because C and C are used to generate strings for human
eyes, they generally must be used "close to the browser". These are
directly in Mason templates, or in functions that return text that
will be passed through Mason. However, in many places in RT we have
hardcoded strings which need translations. For example, the C<$RIGHTS>
hash in F maps rights' names (which must be
translatable) to their descriptions (which also must be translatable).
However, when we're declaring such structures, we do not want to
translate them straight away. RT uses English internally, including
in its web forms, so we do not want to localize rights' names except
for display, otherwise things might break weirdly when you check
if a user has the "Superusuario" right. Furthermore, when we're
declaring such data structures at compile time, there is no current
user to select which language to use for localization. Thus, we
cannot call C when declaring C<$RIGHTS> and other similar
places.
For this reason, F lets you
denote translatable strings with comments. That's what the C<#loc_pair>
comments in the C<$RIGHTS> hash in F indicate.
Since we have those comments, our toolchain will put the rights'
names and descriptions into F files, which enables
translation by our lovely volunteers. Later on, when RT displays
information about rights in the web UI, we'll pass the right's name
through C, and L will then be able to find
our "Superusuario". So although we never used a literal
C, we still get its effects thanks to the
C<#loc_pair> comments and using C.
C<#loc_pair> is used for declaring that the both the key and value
of a particular C<< key => value >> pair are translatable. There
are other markers that you can use.
C<#loc> is used for declaring that a particular string is translatable.
Its parsing is pretty strict so you can use it to declare that only
the value of a particular C<< key => value >> pair is translatable.
C<#loc_left_pair> is used for declaring that the I of a
particular C<< key => value >> pair is translatable. This is of
very limited usefulness.
C<#loc_right_pair> does NOT exist. C<#loc> works in such cases since its
parser does not extend beyond the string at the end of a line. However,
if the string is I at the end of the line, C<#loc{word}> declares
that the value associated with the key I (earlier on the same
line) is to be loc'd. This is useful for inline hashes:
# Note the string "baz" is to be loc'd
foo => { bar => "baz", troz => "zort" }, # loc{bar}

=head2 Test suite
RT also comes with a fairly complete test suite. To run it, you will
need to set environment variables to a database user and password which
can create and drop databases:
export RT_DBA_USER=root
export RT_DBA_PASSWORD=
You'll need to configure RT and make sure you have all the dependencies
before running tests. To do this in place without installing:
./configure.ac --with-my-user-group --enable-layout=inplace --enable-developer
make testdeps
make fixdeps
Adjust the relevant database options as necessary if you want to test on
Postgres, Oracle, or SQLite. The default is MySQL.
To run the test suite:
make test
If you have multiple processors, you can run the test suite in parallel,
which will be significantly faster:
make test-parallel
The C<*-trunk> and C branches are expected to always be passing
all tests. While it is acceptable to break tests in an intermediate
commit, a branch which does not pass tests will not be merged. Ideally,
commits which fix a bug should also include a testcase which fails
before the fix and succeeds after.
=head1 git quickstart
The process below describes how to get a copy of an RT repo,
modify it, and submit your changes as a patch. You can also create
an account on GitHub, fork RT, and submit a PR. GitHub has documentation
on this process: L.
=over
=item 1.
You will first need to obtain a copy of git; this is accomplished via
C in RedHat and derivatives, or C for Debian or Ubuntu.
=item 2.
Next, obtain a copy of the RT source from git:
git clone git://github.com/bestpractical/rt.git
cd rt
=item 3.
Configure git to know your name and email address; git uses these when
it makes commits.
git config user.email your.email@example.com
git config user.name Examp L. Name
=item 4.
Switch to the appropriate point to base your work on; this is generally
C followed by the major version, followed by C<-trunk>. For
example, if your bug was observed in version 3.8.9, you would choose
C; if it was in 4.0.0, you would choose
C. New features should be based on C.
git checkout --track origin/4.0-trunk
=item 5.
Give your branch a name based on what you are attempting to accomplish.
We suggest that branch names be lower-case and separate words with
dashes, but this branch name is purely for your own reference.
git branch -m gnupg-encryption
=item 6.
Edit the source tree to make your changes. A few commands you may find
useful in doing so are listed below.
To see what files you have changed:
git status
To see a line-by-line list of changes:
git diff
To revert a file to the original version:
git checkout path/to/file
To revert only individual parts of a file:
git checkout -p path/to/file
See L for more tips for working with the RT codebase.
=item 7.
Check that you have no extraneous changes using C, then commit
your changes:
git commit -a
You will be prompted to type your commit message. The first line should
be a short (E 80 character) summary of the changes, followed by a
blank line, followed by a longer description, if necessary. The commit
message should not simply restate the diff of which lines were added and
subtracted, but should rather explain B those changes accomplish,
and B they are desired.
If your changes are easily split into multiple components, you may wish
to split your changes into more than one commit; simply return to step 6
and repeat the with the next related change. If your changes are B
related to each other, you should submit them separately; finish step 9,
then start over from step 4.
=item 8.
Save your commits to patch files:
git format-patch @{u}
This will print out the names of the files as it creates them.
=item 9.
Attach these files to an email using your standard email client, and
send it to C. This will create a ticket in
our public RT instance at L.
=back
If you have another bug or feature to implement, simply restart the
process at step 4.
