[Bioperl-l] Re: entrezgene binary ASN

[Hilmar Lapp]

I've tried to listen in on the exchange but I'm not sure I understand 
what the issue is.

I.e., does the parser need to seek in the stream? If yes, then piping 
won't do any good if it works at all. If no, then the parser should be 
perfectly fine with the filename being output from a pipe, and possibly 
accept a file handle in substitution too. In that case, the caller can 
pipe the actual input through any commands he/she wishes by simply 
passing the piped command(s) (e.g. as in "gzip -d -c 
file.asn.gz|gene2xml|").

The parser doing this auto-magically isn't necessary and doesn't save a 
caller that much. Instead, it exposes the parser to liabilities like 
path of gzip, path of gene2xml and similar stuff which may not be 
identical on all platforms.

What am I missing?
