Svgbob specification

Svgbob is a diagramming model which uses common typing characters to approximate the shape

Principle

The rendered shape should closely resembles to that of the ascii drawing / formation.

Non-goals

The goal is NOT to be able to make graphs and diagrams with less effort.

Default sizes

Text height is 2 times the text width, both should be a multiple of 4.

Default values: - text width = 8px; - text height = 16px;

Vertical line |

• if next to an alphanumeric character it will be rendered as text.
• if next to another drawing character it will be rendered as vertical line.
• if alone it will be rendered as vertical line

Example 1:

|
|

use as or expression
Example 2: 
    a||b   <text>a||b</text>

Forward slash /

• if next to an alphanumeric character it will be rendered as text.
• if at least one if its 8 neighbors: (top,bottom,left,right, topleft, topright, bottomleft, bottomright) is a drawing character then it will be rendered as a slanted line to the right
• if used as text but next to a drawing element at the same time, rendering to drawing element takes precedence.

Example 1:

 /
/

Example 2:

Example 3: Aligned next to a drawing element

Backward slash \

• if next to an alphanumeric character, then it will be rendered as text
• if connects to a drawing element, then it will be rendered as a slanted line to the left
• if alone then it will be rendered as slanted line to the left

Example 1:

 \
  \

Example 2:

Cross +

• If the left side is horizontal, then this will become a horizontal line connecting midway to the left
• If the right side is horizontal, then this will come a horizontal line connecting midway to the right
• If top of this character is a vertical line, then this will become a vertical line connecting midway to the the top
• If bottom of this is a vertical line, then this will become a vertical line connecting miday to bottom
