Rethoth 0.4.2 (2017)

Rehoth is a simple to understand, run and maintain Ruby blogging engine

Rethoth (previously known as Thoth) is written in Ruby and is based on the Ramaze web framework and the Sequel database toolkit. Rethoth 0.4.x is a modern port, to 2017, of the original Thoth created by @ryangrove.

Try Rethoth now!

For a quick start using SQLite3 as a database:

    gem install rethoth
    gem install sqlite3
	thoth --create test_project
	cd test_project
	thoth --migrate

Then, point your browser to http://localhost:7000/admin and use 'thoth' as your username and password.

If you want to run or migrate in development mode use the --devel switch e.g.,

	thoth --devel --migrate
	thoth --devel

Note that the name of the executable is still thoth.

Thoth was resurrected, updated and brought to 2017 by John Pagonis (@pagojo). It was originally developed between 2008 and 2012 by Ryan Grove (@rgrove). Thank you Ryan! Steven Bedrick (@stevenbedrick) has also contributed.

We had to rename the project to Rethoth due to project name clashes on the Rubygems site.
