Howerpoint - forget about Powerpoint!!

• ghci terminal-based slide-show presentations that you can control from the REPL and execute code on slides
• idea (no code) stolen from REPLesent

It's only a single Haskell file!

To run presentation create presentation as a text file. Run stack ghci and have in the in the root of the project

$ stack ghci
Howerpoint> :loadPresentation PATH-TO-PRESENTATION

Good stating poitn is test presentations

$ stack ghci
Howerpoint> :loadTestPresentation

Navigation commands

Command	Description
:loadTestPresentation	Load test presentation
:loadPresentation <PATH-TO-YOUR-PRESENTATION>	Load your presentation
help	Help
n	Go to next slide
p	Go to previous slide
nn i	Advance i slides
pp i	Go back i slides
g i	Go to slide i
:rr	Run code from slide
:rrr	Run code from current and all previous slides
resetSize	Set the slide size to current terminal size
setSize x y	Set the slide size to x y
showSize	Show current slide size

ANSI colors

Escape code	Result
\x	Foreground color, where x is one of: black, red, green, yellow, blue, magenta, cyan, white
\X	Background color, where capital X is one of the same as above
\0	Resets foreground and background colors to terminal default

Code

All code is run in ghci so don't forget lets and :m + as imports etc.

>>> show code on a slide and also the same code will be run

>>>putStrLn . show $ double 5

L>> show code on a slide and when the code is run it prepends let

L>>double x = x + x

H>> doesn't show code on a slide but the code is run. It's useful for imports

H>>:m +Data.Char
