Data.GraphViz.PreProcessing

"Real life" Dot code contains various items that are not directly parseable by this library. This module defines the preProcess function to remove these components, which include:

• Comments (both /* ... */ style and // ... style);
• Pre-processor lines (lines starting with a #);
• Split lines (by inserting a \ the rest of that "line" is continued on the next line).
• Strings concatenated together using "..." + "..."; these are concatenated into one big string.
