The PR to GR Converter
General
The PR to GR Converter performs a conversion from SDL/PR files into SDL/GR diagrams. (It is also possible to input SDL/GR diagrams, which transforms them to new SDL/GR diagrams, applying default layouting algorithms.)
Conversion is done on a one-diagram-per-file basis, meaning that each generated GR diagram will be stored on one file. However, entering a PR file may generate multiple GR diagrams, depending on the contents of the PR file.
Conversion Principles
The Analyzer passes which are performed are:
- Macro expansion (if the PR input contains macro definitions).
- Syntax analysis.
- PR to GR conversion.
- Then, graphical layouting is done by the SDL Editor.
Resulting files
The result from the PR to GR conversion is a number of SDL/GR binary files. Each diagram will be stored on one file.
To reconstruct the SDL diagram structure, the Organizer's command Import SDL should be used (see Import SDL).
