The custom queries are configured in rebar.config via the tuple {xref_queries, [{query(), query_result()},...]}. The implementation passes the query() string to xref:q and compares the return value with query_result(). It will result in an error if they do not match. The following configuration, for example, is the same as running the xref check undefined_function_calls. It additionally filters ejabberd_logger:*_msg/4 from the result as these functions are generated on execution by ejabberd and not available at compile time. {xref_queries, [{"(XC - UC) || (XU - X - B - (\"ejabberd_logger\":\".*_msg\"/\"4\"))",[]}]}. This patch also modifies the build process of this package by running a custom query instead of doing a diff against a static xref_warning file. |

rebar
rebar is an Erlang build tool that makes it easy to compile and
test Erlang applications, port drivers and releases.
rebar is a self-contained Erlang script, so it's easy to distribute or even
embed directly in a project. Where possible, rebar uses standard Erlang/OTP
conventions for project structures, thus minimizing the amount of build
configuration work. rebar also provides dependency management, enabling
application writers to easily re-use common libraries from a variety of
locations (git, hg, etc).
Building
Information on building and installing Erlang/OTP can be found here (more info).
Dependencies
To build rebar you will need a working installation of Erlang R13B03 (or later).
Should you want to clone the rebar repository, you will also require git.
Downloading
Clone the git repository:
$ git clone git://github.com/basho/rebar.git
Building rebar
$ cd rebar
$ ./bootstrap
Recompile: src/getopt
...
Recompile: src/rebar_utils
==> rebar (compile)
Congratulations! You now have a self-contained script called "rebar" in
your current working directory. Place this script anywhere in your path
and you can use rebar to build OTP-compliant apps.
Contributing to rebar
Pull requests and branching
Use one topic branch per pull request.
Do not commit to master in your fork.
Provide a clean branch without any merge commits from upstream.
Usually you should squash any intermediate commits into the original single commit.
Code style
Do not introduce trailing whitespace.
Do not mix spaces and tabs.
Do not introduce lines longer than 80 characters.
erlang-mode (emacs) indentation is preferred. vi-only users are encouraged to give Vim emulation (more info) a try.
Writing Commit Messages
Structure your commit message like this:
One line summary (less than 50 characters) Longer description (wrap at 72 characters)
Summary
- Less than 50 characters
- What was changed
- Imperative present tense (fix, add, change)
Fix bug 123
Add 'foobar' command
Change default timeout to 123
- No period
Description
- Wrap at 72 characters
- Why, explain intention and implementation approach
- Present tense
Atomicity
- Break up logical changes
- Make whitespace changes separately
Dialyzer and Tidier
Before you submit a patch check for xref and Dialyzer warnings.
A successful run of make check
looks like:
$ make check
Recompile: src/rebar_core
==> rebar (compile)
Command 'debug' not understood or not applicable
Congratulations! You now have a self-contained script called "rebar" in
your current working directory. Place this script anywhere in your path
and you can use rebar to build OTP-compliant apps.
make: [xref_warnings] Error 1 (ignored)
make: [dialyzer_warnings] Error 2 (ignored)
xref and
Dialyzer warnings are compared
against a set of safe-to-ignore warnings
found in
dialyzer_reference
and
xref_reference.
It is strongly recommended to check the code with
Tidier.
Select all transformation options and enable automatic
transformation.
If Tidier suggests a transformation apply the changes manually
to the source code.
Do not use the code from the tarball (out.tgz) as it will have
white-space changes
applied by Erlang's pretty-printer.
