lfe-utils

Deprecated

This project has been deprecated in favor of lutil (which has 100% inherited from lfe-utils).

Introduction

Convenience functions that can be included in a rebar deps declaration instead of reimplementing across multiple projects.

Dependencies

This project assumes that you have rebar installed somwhere in your $PATH.

This project depends upon the following, which installed to the deps directory of this project when you run make deps:

• LFE (Lisp Flavored Erlang; needed only to compile)
• lfeunit (needed only to run the unit tests)

Installation

In your rebar.config file, update your deps section to include lfe-utils:

{deps, [
  {lfe, ".*", {git, "git://github.com/rvirding/lfe.git", "develop"}},
  {'lfe-utils', ".*", {git, "git://github.com/lfe/lfe-utils.git"}},
  {lfeunit, ".*", {git, "git://github.com/lfe/lfeunit.git"}}
]}

Usage

Usage is the same as any other Erlang or LFE library :-)
