Simple DSL to define parser for flat files formats common in biofinformatics, such as Swissprot, Uniprot, KEGG, TREMBL, etc.
SwissParser API was changed in its version 1.0.0 to simplify parser definition. The code was tested on entire Uniprot and KEGG releases and functional testing guarantees that existing features will not break after an update.
The 1.x versions represent an API change which is not backward compatible. However, the rules definitions and helper need small changes. A wiki page will soon give instructions for updating your parsers.
-
Defines parsers with a clear and compact declarative syntax.
-
The whole parsing workflow is configurable.
-
Able to parse remote files accessible from a web or an FTP server.
-
Users can create new parsers by extending existing parsers.
-
Parser rules have access to user defined helper methods.
