Figlet.Parser.FontFileParser (figlet v0.2.0) View Source
This module parses figlet font files identified by the path to the file.
A FIGlet file has 3 main parts:
- Headerline
- Comments
- Character Data
FIGcharacter Data
The FIGcharacter data begins on the next line after the comments and continues to the end of the file.
Basic Data Structure
The sub-characters in the file are given exactly as they should be output, with two exceptions:
- Hardblanks should be the hardblank character specified in the header line, not a blank (space).
- Every line has one or two endmark characters, whose column locations define the width of each FIGcharacter.
In most FIGfonts, the endmark character is either "@" or "#". The FIGdriver will eliminate the last block of consecutive equal characters from each line of sub-characters when the font is read in. By convention, the last line of a FIGcharacter has two endmarks, while all the rest have one. This makes it easy to see where FIGcharacters begin and end. No line should have more than two endmarks.
