## 29.9 Chapter Exercises
|
||
|
|
|
||
|
|
### File I/O with Vigenère
|
||
|
|
|
||
|
|
see [src/Vigenere.hs](./src/Vigenere.hs)
|
||
|
|
|
||
|
|
```shell
|
||
|
|
> echo "this is a test!" | ./Vigenere -e blah | ./Vigenere -d blah
|
||
|
|
this is a test!
|
||
|
|
```
|
||
|
|
|
||
|
|
### Add timeouts to your utility
|
||
|
|
|
||
|
|
see [src/Vigenere.hs](./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](./src/IniDir.hs)
|
||
|
|
|
||
|
|
There are some bugs in my parser (e.g. comments after values), but the logic
|
||
|
|
of checking the dirctory works!
