Re: store file handles in a hash

in reply to store file handles in a hash

From print:

If you're storing handles in an array or hash, or in general whenever you're using any expression more complex than a bareword handle or a plain, unsubscripted scalar variable to retrieve it, you will have to use a block returning the filehandle value instead...

So, just change the last line in the while loop to:

say { $handles{$file_out} } join "\t", @some_data;

Hope that helps,

[Corion]: erix: Yes, but that's mostly for skipping characters you'll never read, but this approach skips the problem of needing to load more data while looking at a half-match
[Corion]: I mostly wonder how I can add this "reversal" to my toolchest, and if it's worth it or just clever
[choroba]: It should greatly simplify the parsing code, no flags or additional reading of the next buffer needed
