29 IO

29.9 Chapter Exercises

File I/O with Vigenère

see src/Vigenere.hs

> echo "this is a test!" | ./Vigenere -e blah | ./Vigenere -d blah
this is a test!

Add timeouts to your utility

see src/Vigenere.hs

The hWaitForInput does not work so well though. It needs a newline to not timeout. Or, of course, an EOF.

Config Directories

see src/IniDir.hs

There are some bugs in my parser (e.g. comments after values), but the logic of checking the dirctory works!
