Usage

CLI Tool

char-code-at can be used as a CLI tool. Most simply:

λ char-code-at Hi

CHAR: "H"               CHAR CODE: 72
CHAR: "i"               CHAR CODE: 105

You can also pass in whitespace:

λ char-code-at "Hi, world"

CHAR: "H"               CHAR CODE: 72
CHAR: "i"               CHAR CODE: 105
CHAR: ","               CHAR CODE: 44
CHAR: " "               CHAR CODE: 32
CHAR: "w"               CHAR CODE: 119
CHAR: "o"               CHAR CODE: 111
CHAR: "r"               CHAR CODE: 114
CHAR: "l"               CHAR CODE: 108
CHAR: "d"               CHAR CODE: 100

The --start or -s flag indicates the first index that will be analyzed:

λ char-code-at Hello -s 2

CHAR: "l"               CHAR CODE: 108
CHAR: "l"               CHAR CODE: 108
CHAR: "o"               CHAR CODE: 111

Conversely, the --end or -e flag indicates the last index that will be analyzed:

λ char-code-at Hello -e 2

CHAR: "H"               CHAR CODE: 72
CHAR: "e"               CHAR CODE: 101
CHAR: "l"               CHAR CODE: 108

Use both flags together to narrow your results even further:

λ char-code-at "Hi, world" -s 4 -e 5

CHAR: "w"               CHAR CODE: 119
CHAR: "o"               CHAR CODE: 111
