"until programmers stop acting like obfuscation is morally hazardous,
they’re not artists, just kids who don’t want their food to touch." - _why

A Sinatra implementation in less than 10 lines. Dependencies: Tilt and Rack (like Sinatra). Only works on Ruby 1.9.

Features:

• all template engines Sinatra supports
• get/post/put/delete
• before filters
• configure/set/enable/disable/...
• session/params
• support for helpers
• stand alone usage
• inline templates
• thread safe
• works with Padrino

It is considered fully compatible with Sinatra. If your app does not run with Almost Sinatra, please open a Sinatra issue.

Copy the contents of almost_sinatra.rb into your app file (at the top), that way you also avoid running the wrong version by accident.

When pasting the Almost Sinatra code into your file, replace Application=$a with Base=$a (second line atm, but don't expect me to update the readme if I move stuff around).

It's just amazing. No code is faster than no code.

As you can see Sinatra is 1000000% more expensive than Almost Sinatra!

Generated using David A. Wheeler's 'SLOCCount'.

• keep code under ten lines, this includes require and whatnot

• avoid spaces and newlines if possible

• wrap at 200 characters to make it readable on a terminal

• newlines may be used instead of ; to improve readability

• use map instead of each, it's shorter

• store constants in global variables to dry up your code (like $f = File)

• if you have one loop, reuse it. instead of this:

    ['a','b'].map{|e|...}
    [Rack::Something].map{|e|...}
  

  do this:

    ['a','b',Rack::Something].map{|e|(e==e.to_s)?(...):(...)}
  

  Saves a line!

• e=="#{e}" is shorter than e.is_a? String or String===e

• use ->{} instead of proc or lambda (this is why it depends on 1.9)

• add methods for class scope to $o and for instance scope to $a (or $o), see Scopes And Binding

• don't include tests. tests just bloat the code base. just commit, the users will complain if you break anything.
