Inject file into package

[dustekin]

Is there a command line sequence to allow me to inject files in a hpk package giving the path within the package?

Example Jagged Alliance 3 -

Say we have a folder C:\something\UI\Mercs unpacked from UI.hpk. I modify the files in \Mercs. I then have a couple of files, and I know their paths. Can I skip repacking the folder?

Down the line I want to create a bat to inject a selection of files into UI.hpk and distribute it with the modified files, but only the modified files. Is there a way to inject files with the .bat or do I have to run commands to unpack, overwrite and repack.

I looked through your documentation but I'm stuck.

Editing files is currently not possible. You can only recreate them.

I could think of a merge or concat command that is doing the unpacking, overwriting and repack steps.
Editing would be nice but is more complicated than combining the existing code for a merge command.

[dustekin]

A merge function would be really useful.

Just to be clear, I want to distribute a zip with only the modified files and a bat inside it, plus maybe your hpk package as a mod package so a user can just put the zip content into the same folder as the .hpk file and run it. I don't want to provide the 1GB sized asset package with a couple of change megabytes of files.

If you can compile it then you can test the new hpk merge command from the merge-command branch.

hpk merge --dont-compress-files a.hpk b.hpk c.hpk output.hpk

Merge a new hpk archive

Usage: hpk merge [OPTIONS] <input>... <output>

Arguments:
  <input>...  input files
  <output>    hpk output file

Options:
      --compress
          Compress the whole hpk file
      --chunk-size <SIZE>
          Default chunk size: 32768
      --with-filedates
          Stores the last modification times in a _filedates file
      --filedate-fmt <FORMAT>
          Specifies the format of the stored filedates.

          default: 'Windows file time' used by Tropico 3 and Grand Ages: Rome
          short: 'Windows file time / 2000' used by Tropico 4 and Omerta
      --dont-compress-files
          No files are compressed. Overrides `--extensions`
      --extensions <EXT>...

Or you can find the build artifacts from the branch in the actions runs https://github.com/nickelc/hpk/actions/runs/5596777024.

Cool! I'm working on modding the files and will test when I can. You rock!
