== Description

Augment is a framework for gathering metadata from code and displaying it. This metadata would include test failures, test coverage levels, complexity metrics, and others. Display frontends will be pluggable so as to interface with many editors.

== Usage

The +augment+ executable gathers metadata in the form of layers for a given file via a backend. Some backends gather data for a file other than the original one passed in. (The test backend will store data for the test if you pass in the implementation.)

Example:

$ augment test lib/foo.rb # will store metadata for test/test_foo.rb

You can also use the +augment+ executable to display stored metadata. The simplest frontend is +color+ which outputs the layers via ANSI color codes to the shell:

$ augment color test/test_foo.rb

Most other frontends are editor-specific.

== Design

Augment is designed to be generalized; if you want to collect different kinds of data you can just write a new backend. If you want to display the data in an unsupported editor or output format, you can write a new frontend.

=== Backends

Each backend takes a filename or glob and outputs the metadata about that file into the .augment directory, created in the project root. Metadata is stored as layer information in JSON. Each backend also needs an initiator command to kick off the process that gathers the metadata, with the exception of auto-initiating backends like autotest.

=== Frontends

Most frontends are implemented within an editor or IDE. They watch the .augment directory for changes and apply them to the open buffers when they happen. The user can choose what augmentations he wants displayed either globally or on a per-file basis. He can also control when backend initiators should be started, though usually these will be kicked off automatically upon saving a file.

=== Layers

A layer consists of a single piece of metadata about a file. This is expressed in terms of the range it applies to in the file, its color, and the message associated with it.

== Support

Backends:

• Tests (miniunit)
• Rspec (planned)
• Heckle (planned)
• Rcov (planned)
• Flog (planned)
• Performance (planned)

Frontends:

• ANSI color codes (for shells)
• HTML
• Emacs
• Textmate (planned)
• Vim (planned, need help)

== Issues

• A bit short on frontends and backends.
