This change makes it possible to type the beginning (the prefix) of a
command name and rebar will guess the full name of the command,
thereby saving the user precious keystrokes. As long as the prefix
matches only one command, rebar runs that command, otherwise rebar
prints a list of candidate command names. The "-" character is
considered to be a word separator and the prefix matching is done per
word.
Example prefix matches:
co ==> compile
cl ==> clean
create ==> create
create-a ==> create-app
c-a ==> create-app
c-app ==> create-app

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.
