OpenBook

OpenBook is a command line application to assist with open book exams.

Install

You will need to have cabal and GHC installed. You simply navigate to the clones directory and simply type

cabal v2-build
./copyExec.sh [Install dir]

The script will not work on windows

Demo

Input multiple file and fast search (gif play-back is ironically slow)

Mouse and Unicode Support

Picture support on Mac OS (and linux if you change a line of code)

Usage

When it is completed, you will simply run OpenBook [filename] where the file is a store of all the data you might want to look up in the exam.

• When the app is running, 'ESC' closes the app, type to search and arrow keys to select a hit.
• Clicking on "See also" or "related" section will jump there
• On MacOS Only, clicking on a "File : " section will open the file in QuickLook

Inputing data

Data is input in .ob files. Here is an example file:

#title Monad
A Monad is a type constructor, M, together with an instance of return and bind

#def Monad Laws
The monad laws are the following:
Associativity:
  (xm $> f) $> g = xm $> (\x -> f x $> g)
Identity:
  (result x) $> f = f x
  xm $> result = xm

#eqn monad-eqn
result :: a -> M a
($>) :: M a -> (a -> M b) -> M b

#title Continuation Monad
The continuation monad encapsulates continuations

#def ContMonadDef
type M a = (a -> Ans) -> Ans

#is Monad
-

#eqn contMonadEq
result x k = k x 

(x $> f) k = x (\x -> f x k)

Getting file support working on linux

In src/Main.hs (as of writing line 72) there is a line that looks like this:

handleEvent entries s (MouseDown (Extern path) button mods coords) = (liftIO $ spawnCommand ("qlmanage -p " ++ path ++ " >& /dev/null")) >> continue s

swap out qlmanage -p with whatever file opening command you want!

TODO List

• Build UI
• Design file format and parser for text
• Implement search utility
• Implement more focuses search
