banner-in-sed

A small utility for printing an "ASCII-art" banner for a given string. This sed-script essentially concatenates a predefined matrices corresponding to the characters of a string. Supports autokerning, i.e. automatic fitting of character matrices to optimize intercharacter distances.

(There is also support for the animation of the kerning process, just-for-fun.)

Possible uses:

• After-login banner,
• Popup message,
• CAPTCHA. :)

Limitations:

• No "smushing" (see documentation in figlet distribution for definitions); autokerning stops when the neighbor matrices touch,
• No multiple lines of text (may be fixed in the future),
• Many more limitations; it's hard even to list them :).

Closest analogs: banner (or sysvbanner), figlet (см. также репозиторий на GitHub).

Usage:

./generate.sh 3x5.flf
echo Hello | ./banner.sed

(Contains 3x5.flf font from the figlet distribution. See the file (as text) for copyright information.)

Read the code in banner.code.part, generate.sh, and import-font.sed for detailed information on the implementation.
