README

# RailRoady

[![Build Status](https://travis-ci.org/preston/railroady.svg?branch=master)](https://travis-ci.org/preston/railroady)

RailRoady generates Rails model (ActiveRecord, Mongoid, Datamapper) and controller UML diagrams as cross-platform .svg files, as well as in the DOT language.

Code is based on the original "railroad" gem, patched and maintained over the years. Lineage can be traced via GitHub.

I (Preston Lee) am not trying to hijack Peter Hoeg or Javier's project, but rather create a dedicated, lean gem that can be used without major issue on Rails projects.

# System Requirements

You MUST have the the following utilities available at the command line.
* `dot` and `neato`.

* `sed`, which should already be available on all sane UNIX systems.

## Mac users

Brew users can install via:

brew install graphviz

MacPorts users can install in via

sudo port install graphviz

## Ubuntu users

Ubuntu users can install in via

sudo apt-get install graphviz

# Usage

The easiest (and recommend) usage is to include railroady as a development dependency with your Rails 3 Gemfile, like so...

group :development, :test do
gem 'railroady'
end

...and then run the master rake task...

rake diagram:all

This should generate four doc/\*.svg files that can be opened in (most) web browsers as well as dedicated document viewers supporting the Scalable Vector Graphics format.

## Support for Engines

Generate diagram for models and controllers including those in the engines.

rake diagram:all_with_engines

## Alternate Usage

Alternatively, you may run the 'railroady' command-line program at the Rails application's root directory. You can redirect its output to a .dot file or pipe it to the dot or neato utilities to produce a graphic. Model diagrams are intended to be processed using dot and controller diagrams are best processed using neato.

railroady [options] command

## Options

Common options:
-b, --brief Generate compact diagram
(no attributes nor methods)
-s, --specify file1[,fileN] Specify only given files
-e, --exclude file1[,fileN] Exclude given files
-i, --inheritance Include inheritance relations
-l, --label Add a label with diagram information
(type, date, migration, version)
-o, --output FILE Write diagram to file FILE
-r, --root PATH Set PATH as the application root
-v, --verbose Enable verbose output
(produce messages to STDOUT)
-x, --xmi Produce XMI instead of DOT
(for UML tools)
--alphabetize Sort methods alphabetically

Models diagram options:
-a, --all Include all models
(not only ActiveRecord::Base derived)
--show-belongs_to Show belongs_to associations
--hide-through Hide through associations
--all-columns Show all columns (not just content columns)
--hide-magic Hide magic field names
--hide-types Hide attributes type
-j, --join Concentrate edges
-m, --modules Include modules
-p, --plugins-models Include plugins models
-z, --engine-models Include engine models
--include-concerns Include models in concerns subdirectory
-t, --transitive Include transitive associations
(through inheritance)

Controllers diagram options:
--hide-public Hide public methods
--hide-protected Hide protected methods
--hide-private Hide private methods
--engine-controllers Include engine controllers

Other options:
-h, --help Show this message
--version Show version and copyright

-c, --config FILE File to load environment (defaults to config/environment)

## Commands

You must supply one of these:

-M, --models Generate models diagram
-C, --controllers Generate controllers diagram
-A, --aasm Generate "acts as state machine" diagram

## Examples

railroady -o models.dot -M
Produces a models diagram to the file 'models.dot'
railroady -a -i -o full_models.dot -M
Models diagram with all classes showing inheritance relations
railroady -M | dot -Tsvg > models.svg
Model diagram in SVG format
railroady -C | neato -Tpng > controllers.png
Controller diagram in PNG format
railroady -h
Shows usage help

# Processing DOT files

To produce a PNG image from model diagram generated by RailRoady you can
issue the following command:

dot -Tpng models.dot > models.png

If you want to do the same with a controller diagram, use neato instead of
dot:

neato -Tpng controllers.dot > controllers.png

If you want to produce SVG (vectorial, scalable, editable) files, you can do
the following:

dot -Tsvg models.dot > models.svg
neato -Tsvg controllers.dot > controllers.svg

Important: There is a bug in Graphviz tools when generating SVG files that
cause a text overflow. You can solve this problem editing (with a text
editor, not a graphical SVG editor) the file and replacing around line 12
"font-size:14.00;" by "font-size:11.00;", or by issuing the following command
(see "man sed"):

sed -i 's/font-size:14.00/font-size:11.00/g' file.svg

Note: For viewing and editing SVG there is an excellent opensource tool
called Inkscape (similar to Adobe Illustrator. For DOT processing you can
also use Omnigraffle (on Mac OS X).

= Rake Tasks

As of Preston Lee's Rails 3/4/5 modifications, including RailRoady as a project development dependency will automatically add a set of rake tasks to your project. Sweet! (Run `rake -T` to check them out.)

# Requirements

RailRoady has been tested with the following Ruby and Rails versions

## Ruby
* 1.9.2+
* 2.0.0+

## Rails
* 3.0.3+
* 4.0.0+
* 5.0.0+

There are no additional requirements (nevertheless, all your Rails application
requirements must be installed).

In order to view/export the DOT diagrams, you'll need the processing tools
from Graphviz.
