Create Parsers

The parsers folder should contain a pkgIndex.tcl with the package name and the list of .tcl files used to extract the metadata from the content. It should also contain a Tcl Script, which parses the content to extract the metadata.

create_parsers

A typical parser does the following:

•	Checks if the parsing is possible by verifying the file extension. Or, if the file is a ASCII solver deck, parses the related solver cards.

•	Parses the file and extracts the metadata.

•	Adds the extracted metadata to the content.

A typical parser is shown below.

typical_parser

Name	Description
Package name (1)	Should be the same in pkgIndex.tcl.
Procedure name (2)	Used to check if the file can be parsed. This procedure should be ::namespace::imp_canParse. The core application expects a return from the procedure with this name. A return value of 0 means the file cannot be parsed. The file will be treated as a generic file and listed the same in the Organize browser. A return value of 1 means that the file can be parsed.
Procedure name (3)	Used to parse the metadata and pass the extracted metadata to core. The name of this procedure should be ::namespace::imp_parse. A return value of 0 should be set to indicate the successful parsing.
