Today I have officially released Facets 2.0.0.
gem install facets
Facets 2.0.0 represent the project’s official push into “production
ready” status --a major departure from the 1.x series which was
focused on acquiring functionality. For more information about this
release see the README below.
As with any zero-point release, I expect some minor releases to
quickly follow. Please, let me know if you encounter any problems so I
can get them fixed right away.
Special thanks to everyone that helped me get this release together!
T.
= Ruby F.s
“ALL YOUR BASE ARE BELONG TO RUBY”
== Introduction
Ruby F.s is the single largest collection of general purpose method
extensions and system additions for the Ruby programming language.
The core extensions is a large collection of methods which extend the
core capabilities of Ruby’s built-in classes and modules. This
collection of extension methods are unique by virtue of their
atomicity. The methods are stored in relatively small groups of
tightly coupled methods so that each can be required independently.
This gives developers the potential for much finer control over which
extra methods to bring into their code.
The “more” additions are a collection of classes, modules and light
meta-systems which constitutes an ever improving source of reusable
components. Some very nice additions are provided, from the simple
Functor class to a full-blown annotations system.
== Installation
You can install either via RubyGems or manually:
% gem install facets
or
% tar -xzf facets-2.x.x.tar.gz
% cd facets-2.x.x
% sudo task/install
IMPORTANT! Note that setup.rb is no longer used due to Facets new
special layout.
== Compatibility with 1.x series.
Prior to 2.0, Facets was divided between CORE and MORE --standalone
extensions vs. classes and modules, respectively. With 2.0, the idea
of CORE has take only a slightly new meaning. Instead CORE now
represents the libraries that are considered essential and as such are
loaded automatically when using ++require “facets”++. While still
primarily made up of extension methods a few classes now belong to
core as well. In conjunction with this the extension methods are no
longer stored on a per-method basis, but rather in tight knit packs.
While dividing the extension methods up on a per-method basis had
certain advantages, not the least of which was a simple organization,
it proved too granular --rather than “atomic” it was “subatomic”. With
2.0 we have address this issue. All the extension methods have now
been organized into small tightly related groups.
However, being able to require on the basis of a method is still a
useful approach, so a compatibility layer for the 1.x series has been
created. It makes it possible to load Facets libraries on a per method
basis, just as before, via require redirection.
For example:
require ‘facets/core/string/underscore’
Will redirect according to the content of the underscore.rb file:
require ‘facets/string/stylize’
So the underscore method will be loaded just as before. But a few
other stylization methods will be loaded as well. This actually
proves a more useful approach b/c often one will want to use one of
the related methods as well.
== Mission
Facets holds to the notion that the more we can reasonably integrate
into a common foundation directed toward general needs, the better
that foundation will be able to serve everyone. There are a number of
advantages here:
* Better Code-reuse
* Collaborative Improvements
* Greater Name Consistency
* One-stop Shop and Installation
== Status
The current status is quite good. While some parts are still
considered beta, everything is relatively usable.
== Installation
The easiest way to install is via RubyGems. On the command line enter:
gem install facets
To manually install, unpack the .tar.bz2 package and use the included
setup.rb script. For example:
tar -xvzf facets-x.x.x.tar.gz
cd facets-x.x.x
sudo util/setup
On Window the last step will be:
ruby util/setup
== Usage
For detailed usage of any given method or module please refer to the
API RDocs. Most are well documented. Assistance in improving
documentation though is always appreciated.
If you plan to use more then a few of Facets core method it is
recommended that you require require the main facility.
require ‘facets’
This loads all the CORE functionality at once.
Of course you can use the CORE library piecemeal if you prefer. The
general require statement for a core extensions library is:
require ‘facets/<class|module>/’
For example:
require ‘facets/time/stamp’
Most “atoms” contain only a few methods, sometimes only one, but a few
exceptions provide quite a few method, such as ++string/indexable.rb+
+.
You can load per-class or per-module groups of core methods by
requiring the class or module by name. For example"
require ‘facets/time’
Will require all the Time method extensions.
Note that some methods that were part of CORE in 1.8 and earlier are
now part of MORE libraries. A good example is ‘random.rb’. There were
separated b/c they had more specialized usecases, where as CORE
extensions are intended as general purpose.
Using a Facets/MORE library of modules, classes or microframeworks is
essentially the same. For example:
require ‘facets/basicobject’
PLEASE IGNORE THIS FOR NOW
It is possible to eliminate the need for the ‘facets/’ prefix on
requires if the Facets libpaths are added to the LOAD_PATH. But this
isn’t as straight-forward as it is for most libraries b/c of the
layout of Facets library.
require ‘facets-topload’
require ‘basicobject’
Understand that on the off chance that another library has the same
name as one of Facets’ everything will still work fine. You will just
not be able to use the prefixless shortcut to require it.
END IGNORE.
Again, for details pertaining to the functionality of each feature,
please see the API Docs.
== Method File Names
Operator method redirect files are stored using English names. For
instance for Proc#* is ‘proc/op_mul’.
For reference, here is the chart.
+@ => op_plus_self
-@ => op_minus_self
+ => op_plus
- => op_minus
** => op_pow
* => op_mul
/ => op_div
% => op_mod
~ => op_tilde
<=> => op_cmp
<< => op_lshift
>> => op_rshift
< => op_lt
> => op_gt
=== => op_case_eq
== => op_equal
=~ => op_apply
<= => op_lt_eq
>= => op_gt_eq
| => op_or
& => op_and
^ => op_xor
[]= => op_store
[] => op_fetch
Facets simply takes the ‘*’ and translates it into a string acceptable
to all file systems. Also, if a method ends in ‘=’, ‘?’ or ‘!’ it is
simply removed.
== Contribute
This project thrives on contribution.
If you have any extension methods, classes, modules or small
frameworks that you think have general applicability and would like to
see them included in this project, don’t hesitiate to submit. There’s
a very good chance it will be included. Also, if you have better
versions of any thing already included or simply have a patch, they
too are more than welcome. We want Ruby F.s to be of the highest
quality.
