Handle compressed files

[vincentbernat]

Hey!

It would be nice to transparently handle compressed files, like json.gz or json.zstd. Either by guessing file type (with magic bytes?) or just by relying on the extension.

Thanks!

i just came across jless today and i haven't been this happy about finding a new util in a long time... awesome.

i'll second this request with a slight tweak. i don't need built-in support for compression as long as i could do something like this:

gunzip -c /path/to/enormous/file.gz | jless
# results in:
# gunzip: /path/to/enormous/file.gz: unexpected end of file
# gunzip: /path/to/enormous/file.gz: uncompress failed
# Unable to parse input: "Parse error"

my workaround is this, which is GoodEnough for my current usage: gunzip -c /path/to/enormous/file.gz | head -n 10 | jless
