Classes
- Global Functions -- Global functions for flex/bison scanner/parser for MSScanGram (full description)
Interface
- int msScanGramParseCommand (const MeasurementSet *ms, const String& command)
- void MSScanGramerror (char*)
- const TableExprNode *msScanGramParseNode()
- Int& msScanGramPosition()
- int msScanGramInput (char* buf, int max_size)
- String msScanGramRemoveEscapes (const String& in)
- String msScanGramRemoveQuotes (const String& in)
Prerequisite
- MSScanGram.l and .y (flex and bison grammar)
Synopsis
Global functions are needed to define the input of the flex scanner
and to start the bison parser.
The input is taken from a string.
Motivation
It is necessary to be able to give an image expression in ASCII.
This can be used in glish.
