Description
Display token names or rules for specified expression parsers.
In the Lemon grammar, terminals (uppercase) are listed first.
Non-terminals (lowercase) are listed second.
The current OpenFOAM grammar short naming conventions:
- svalue : scalar value
- sfield : scalar field
- lfield : logic field
- vfield : vector field
- tfield : tensor field
- hfield : sphericalTensor field
- yfield : symmTensor field
.
Prefixes: 's' (surface) or 'p' (point).
For example, psfield for a point scalar field
Usage
\b foamExprParserInfo [OPTION]
Options:
- \par -rules
Print parser rules
- \par -tokens
Print token names (default)
- \par -all
Display information for all parsers
- \par -field
Field expression parser information
- \par -patch
Patch expression parser information
- \par -volume
Volume expression parser information
