Writing compressed files

[dhimmel]

Is there currently any way to write to a compressed text file?

Ideally, compression would be automatically detected from the path (ending in .gz, .bz2, or .xz) argument of readr::write_tsv().

The best way to do this is probably to use the C-level connection API (which I think will require a dependency on R 3.3.0), and then create the connection in R code.

What does ready label imply here? Next release?

IMHO, it would be ideal for path to accept R connection (like write.csv does), including gzfile() or bzfile().

It would be nice to have both functionalities:

write_csv(df, bzfile("x.csv.bz2"))

and

read_csv(bzfile("x.csv.bz2"))

instead of replacing the former with:

write.csv(df, bzfile("x.csv.bz2"), row.names = F)
