Per my take-home assignment's reviewer's comments, with which for the record I agree, I should generate the character->coordinate table from my existing qwerty keyboard definition. The best part is: by doing this I found a bug: Notice how the original '0' character was mapped to the Coordinate (0,0)... thus every subsequent digit key (i.e. the first row) is off-by-one. |

Transform QWERTY
Apply a series of transforms to a QWERTY keyboard then use the new keyboard to re-type a passage of text.
Usage
Here are some --help and usage examples:
$ runhaskell Main.hs --help
Usage: Main.hs (-t|--transforms ARG) (-p|--passage ARG)
Transform a QWERTY keyboard using a string of commands
Available options:
-t,--transforms ARG String of transforms where (e.g. "HHVS12VHVHS3")
-p,--passage ARG Input text to re-type
-h,--help Show this help text
Now a working example:
$ runhaskell Main.hs --transforms=HHVS12VHVHS3 --passage='Hello,Brilliant.'
Typing: "Hello,Brilliant."
On this keyboard:
[N][M][,][.][/][Z][X][C][V][B]
[H][J][K][L][;][A][S][D][F][G]
[Y][U][I][O][P][Q][W][E][R][T]
[6][7][8][9][0][1][2][3][4][5]
Result: QKRRF30LDRRDY1;4
...and an example with an erroneous input (i.e. !):
$ runhaskell Main.hs --transforms=HHVS12VHVHS3 --passage='Hello,Brilliant!'
Typing: "Hello,Brilliant!"
On this keyboard:
[N][M][,][.][/][Z][X][C][V][B]
[H][J][K][L][;][A][S][D][F][G]
[Y][U][I][O][P][Q][W][E][R][T]
[6][7][8][9][0][1][2][3][4][5]
Looks like at least one of the characters in your input passage doesn't fit on our QWERTY keyboard:
[1][2][3][4][5][6][7][8][9][0]
[Q][W][E][R][T][Y][U][I][O][P]
[A][S][D][F][G][H][J][K][L][;]
[Z][X][C][V][B][N][M][,][.][/]
Environment
You'll need runhaskell and a few other Haskell libraries, so call nix-shell
from this project's root directory.
Testing
To run the test suite:
$ runhaskell Spec.hs
