Support for vpk format

[darealshinji]

Is it possible to add support for extracting Valve Pak files using the vpk command line tool? https://pypi.org/project/vpk/

Listing content:

# vpk -l maps_dir.vpk
maps/bs_c0m0c.bsp
maps/bs_c0m0b.bsp
maps/bs_c0m0a.bsp

# vpk -la maps_dir.vpk
maps/bs_c0m0c.bsp CRC:611e2b87 Size:14320992
maps/bs_c0m0b.bsp CRC:2ef444a6 Size:20866336
maps/bs_c0m0a.bsp CRC:0ea73c93 Size:21933489

Extract all files: vpk -x outdir maps_dir.vpk

Extract single file without creating directories:
vpk -x outdir --filter maps/bs_c0m0a.bsp --no-directories maps_dir.vpk

On an error vpk returns a line beginning with either Error: or IOError:.

@darealshinji How to achieve vpk compression?

[darealshinji]

An archive is created with vpk -c DIR OUTFILE (vpk archives are not compressed).
The leading directory path is removed:

$ ls test_files
file1.dat  file2.dat
$ vpk -c $HOME/test_files out.vpk
$ vpk -l out.vpk 
file2.dat
file1.dat

Here's the help output:

usage: vpk [-h] [--version] [-l | -la | -t | -c DIR | -p | -x OUT_LOCATION] [-cv {1,2}] [-nd] [-pe ENC] [-f WILDCARD | -re REGEX | -name WILDCARD] [-v] file

Manage Valve Pak files

options:
  -h, --help            show this help message and exit
  --version             show program's version number and exit

Main:
  file                  Input VPK file
  -l, --list            List file paths
  -la                   List file paths, crc, size
  -t, --test            Verify contents
  -c DIR, --create DIR  Create VPK file from directory
  -p, --pipe            Write file contents to stdout
  -x OUT_LOCATION, --extract OUT_LOCATION
                        Extract files to directory
  -cv {1,2}, --create-version {1,2}
                        Create VPK with this version
  -nd, --no-directories
                        Don't create directries during extraction
  -pe ENC, --path-encoding ENC
                        File paths encoding

Filters:
  -f WILDCARD, --filter WILDCARD
                        Wildcard filter for file paths
  -re REGEX, --regex REGEX
                        Regular expression filter for file paths
  -name WILDCARD        Filename wildcard filter
  -v, --invert-match    Use filters for exclusion
