`init:get_plain_arguments()` returns `["console", "more_args"]` when started with `$APP_NAME console more_args`, but `["console"]` when started with `$APP_NAME start more_args`. This patch makes `start` behave like `console` in this respect. |

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
Coding style
Do not introduce trailing whitespace.
Do not introduce lines longer than 80 characters.
Indentation
To have consistent indentation we have vi modeline/emacs local variable
headers in rebar's source files. This works automatically with vi.
With Emacs you have to declare 'erlang-indent-level
set to 4
as a safe local variable value. If not configured Emacs will prompt
you to save this as part of custom-set-variables:
'(safe-local-variable-values (quote ((erlang-indent-level . 4))))
You can also tell Emacs to ignore file variables:
(setq enable-local-variables nil
enable-local-eval nil)
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:
$ cd rebar/ $ ./bootstrap debug $ dialyzer ebin -Wunmatched_returns -Werror_handling -Wrace_conditions -Wunderspecs
The following discrepancies are known and safe to ignore:
rebar_templater.erl:249: The call rebar_templater:consult(
Cont1::erl_scan:return_cont(),'eof',
Acc::[any()])
contains an opaque term as 1st argument when terms
of different types are expected in these positions
rebar_utils.erl:144: Call to missing or unexported function escript:foldl/3
rebar_utils.erl:165: The created fun has no local return
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.
