xopen
import "github.com/shenwei356/xopen"
xopen makes it easy to get buffered (possibly gzip-, xz-, or zstd- compressed) readers and writers. and
close all of the associated files. Ropen opens a file for reading. Wopen opens a
file for writing.
This packages is forked from https://github.com/brentp/xopen , but I have modified too much :(
Usage
Here's how to get a buffered reader:
// gzipped
rdr, err := xopen.Ropen("some.gz")
// xz compressed
rdr, err := xopen.Ropen("some.xz")
// zstd compressed
rdr, err := xopen.Ropen("some.zst")
// normal
rdr, err := xopen.Ropen("some.txt")
// stdin (possibly gzip-, xz-, or zstd-compressed)
rdr, err := xopen.Ropen("-")
// https://
rdr, err := xopen.Ropen("http://example.com/some-file.txt")
// Cmd
rdr, err := xopen.Ropen("| ls -lh somefile.gz")
// User directory:
rdr, err := xopen.Ropen("~/shenwei356/somefile")
checkError(err)
defer checkError(rdr.Close())Writter
wtr, err := xopen.Wopen("some.gz")
defer checkError(wtr.Close())
outfh.Flush()
