Re: OK to use GPLed class libraries in DNA sequencers ( was Re: [dna-dev] Required headers on all files)

I would like us to seriously consider Smooks. I've not had any time to take a look (other than reading some documentation), but it seems very powerful and worth us understanding and leveraging. Like you said, it could provide a consistent solution for a number of sequencers. Great idea, Stefano! BTW, another pattern several sequencers will follow are those that need to parse a grammar-based file, and I'd like those to use ANTLR. We're still investigating the first one (DNA-73), but the goal is that we can use ANTLR grammar to create an abstract syntax tree (AST) of the file, then an ANTLR tree grammar to transform the AST into another AST that has the same structure as the sequencer output graph. Then, a common library would do the work of writing that second AST into the SequencerOutput. If we can do this, then a sequencer would consist almost entirely of two ANTLR grammar files in a Maven project. (We could even create a Maven archetype that would allow Maven to generate the stub of that project.) Best regards, Randall On Jun 13, 2008, at 9:46 AM, Gregory Haber wrote: > That is a great idea!
