Jan Kloetzke b10224be62 Fix rebar_utils:expand_env_variable/3 
The function may fail with a badarg exception because the first regex
returns an iolist() which is allowed to be a improper list. In this case
'++' cannot append to the iolist. The correct way to append something to
an iolist() is

  [iolist(), "tail"]

because iolist's are allowed to be arbitrarily deep lists.

README.md

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 in the INSTALL.md document.

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 discrepancies with Dialyzer:

$ make check

The following discrepancies are known and safe to ignore:

rebar_utils.erl:147: Call to missing or unexported function escript:foldl/3

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.
