That would be cool, but it will need a rewrite of the package. Alternatively, you can try replace the open
with your own, which returns in-memory files. Keep in mind that most VPK for games, have 100s thousands of files, and even storing the file tree is very memory wasteful.
Providing different fopen
function is used in steamctl
to files from inside a VPK directly from the Steam CDN. https://github.com/ValvePython/steamctl/blob/4d6b19a921a4db521ed6e0d05a1dae2458441a9a/steamctl/commands/depot/gcmds.py#L79-L86
In order to create a VPK archive using this project, the files must first exist in the OS's file system. If I read a file and perform some simple string transformations on it in-memory, I would currently need to write the file back to the OS's file system in order to create a VPK archive using this package.
It would be nice if we could create a VPK archive without depending on the OS's file system. This would allow for more flexibility with the project, especially if we could dependency inject a mock file system for unit tests.
One possible proposal is to change the
NewVPK
constructor API of this package to accept a file system object rather than a path to a directory. An example using PyFilesystem could look likePyFilesystem supports in-memory file systems, which could be used in place of
open_fs('./some/directory')
to enable unit tests that do not need to access the OS's file system. Support for creating VPK archives from ZIP and TAR archives for free seems like a neat bonus.
