Box It!

boxit is a small script written in awk and shell that puts text centered in a little ascii box.

This is placed under the unlicense.

#!/bin/sh

NROWS=58 # NROWS - 2

boxit() {
    read -r -d '' SCRIPT <<EOF
BEGIN {
    NROWS=58
    printf "+"
    for (i = 0; i < NROWS; i++) {
        printf "-"
    }
    printf "+\n"
}

{
    lsize = length(\$0)
    lspace = (NROWS - lsize) / 2
    rspace = lspace

    if (lsize % 2 != 0) rspace--;

    printf "|"

    for (i = 0; i < lspace; i++) {
        printf " "
    }

    printf \$0

    for (i = 0; i < rspace; i++) {
        printf " "
    }

    printf "|\n"
}

END {
    printf "+"
    for (i = 0; i < NROWS; i++) {
        printf "-"
    }
    printf "+\n"
}
EOF

awk "$SCRIPT"
}

fold -s -w $NROWS | boxit

Use it like so:

$ printf "do\nall\nthings\nwith\nartlessness" | ./boxit
