I'm looking for a way to automatically handle decompression of files within JS but I'm not seeing any such methods. I was wonder if maybe Archive could be extend to just uncompress .gz .zip .lzh or whatever files or maybe a new method for (de)compression of files.

Maybe something exists already but I'm not seeing it.

Thanks,

Archive has a method called extract().

That extracts from archives or containers. It does not uncompress .gz files.

Right, .gz files aren't archives. No plan to support them directly in SBBS. .tgz / .tar.gz files *are* supported however.

it doesn't really make a lot of sense.. gzip isn't really used that way except for edge cases

.tar.gz
^ ^---- compression - supports only one file
`-------- archive of files, uncompressed

the edge case being generally like:

derp.log.gz
^---- compressing one file, a log

so for SBBS what would be the purpose? so you can view gzipped log files?

well a .gz file is a single compressed file, right?
so why are you saying it's not an archive format?

No, it's a block of compressed data which may not have originally been a file.

so why are you saying it's not an archive format?

Becaue it's not. An archive file/format contains one or more files, their data/contents and metadata about those files (e.g. file name, date/time, size, checksum) - a .gz file doesn't contain any of that.

A .tar file is an archive.
A .gz file is compressed data.
A .tar.gz (or .tgz) is a compressed archive.

well i only worked with .gz files long ago. but only when i HAD to, so i'm a bit confused about why you think that it's not an archive format.

so i used gzip and created an archive

root@linux:~# gzip -l shit.rar.gz
compressed uncompressed ratio uncompressed_name
12861660 12860366 -0.0% shit.rar
root@linux:~# gzip -l -v shit.rar.gz
method crc date time compressed uncompressed ratio uncompressed_name
defla d61855b3 Sep 7 12:47 12861660 12860366 -0.0% shit.rar

as you can see, the archive i created shows crc, date time the compressed and uncompressed size, the ratio and the uncompressed filename
https://i.imgur.com/EwYcPym.png

so it meets the criteria you mentioned for archives, right?
so yes, it's one file but it's a compressed archive.

No.

I listed all the criteria you mentioned and met it with a gzip archive. furthermore, gzip refers to them as archives. https://www.gnu.org/software/gzip/manual/gzip.html

Usage: gzip [OPTION]... [FILE]...
Compress or uncompress FILEs (by default, compress FILES in-place).

Mandatory arguments to long options are mandatory for short options too.

-c, --stdout write on standard output, keep original files unchanged
-d, --decompress decompress
-f, --force force overwrite of output file and compress links
-h, --help give this help
-k, --keep keep (don't delete) input files
-l, --list list compressed file contents
-L, --license display software license
-n, --no-name do not save or restore the original name and timestamp
-N, --name save or restore the original name and timestamp
-q, --quiet suppress all warnings
-r, --recursive operate recursively on directories
--rsyncable make rsync-friendly archive ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

That's for when using gzip along with an archiver (e.g. tar) to create an archive file that have single files extracted even when the parent archive is changed. Read the man page on that option. That option provides no feature/function when not used in combination with an archive program (e.g. tar). gzip is not an archive format or program.

so yes, it's one file but it's a compressed archive.

If a library can only store one book, is it still a library? No, it's not.

if it only had ONE, very good book it would be called the library of [good book].

Per Wikipedia:

Compressed archives are typically created by assembling collections of files into a single tar archive (also called tarball),[7] and then compressing that archive with gzip. The final compressed file usually has the extension .tar.gz or .tgz.

Okay, I'll reference the same man page that you did:

"If you wish to create a single archive file with multiple members so that members can later be extracted independently, use an archiver such as tar or zip. GNU tar supports the -z option to invoke gzip transparently. gzip is designed as a complement to tar, not as a replacement."

They're both correct: gzip is not an archiver tool or an archive file format. --
