# 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:
|
|
|
|
```shell
|
|
$ 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:
|
|
|
|
```shell
|
|
$ 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. `!`):
|
|
|
|
```shell
|
|
$ 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:
|
|
|
|
```shell
|
|
$ runhaskell Spec.hs
|
|
```
