ascii-art

Objectives

Ascii-art is a program which consists in receiving a string as an argument and outputting the string in a graphic representation using ASCII. Time to write big.

What we mean by a graphic representation using ASCII, is to write the string received using ASCII characters, as you can see in the example below:

@@@@@@BB@@@@``^^``^^``@@BB$$@@BB$$
@@%%$$$$^^^^WW&&8888&&^^""BBBB@@@@
@@@@@@""WW8888&&WW888888WW``@@@@$$

  • This project should handle an input with numbers, letters, spaces, special characters and \n.
  • Take a look at the ASCII manual.

Instructions

  • Your project must be written in Go.

  • The code must respect the good practices.

  • It is recommended that the code present a test file.

  • Some banner files with a specific graphical template representation using ASCII will be given. The files are formatted in a way that is not necessary to change them.

Banner Format

  • Each character has a height of 8 lines.
  • Characters are separated by a new line \n.
  • Here is an example of ' ', '!' and '"'(one dot represents one space) :
