dgamelaunch-config

This is a collection of scripts to manage a dgamelaunch (http://nethackwiki.com/wiki/Dgamelaunch) install, all run from an umbrella dgl script.

These are still very incomplete, WIP.

Currently available commands:

1. Update your dgamelaunch config from the repository:

   $ sudo dgl publish --confirm
   

2. Change a dgl user's password:

   $ sudo dgl passwd johndoe
   

3. Update Crawl alpha build from git master:

   $ dgl update-trunk
   

4. Remove stale Crawl alpha versions:

   $ dgl remove-trunks
   

5. Run dgl-whereis inotify daemon:

   $ sudo dgl crawl-inotify-dglwhere
   

   This inotify daemon monitors the dgamelaunch in-progress dirs to keep track of active players, and monitors their morgue directories for changes to their .where files. When a .where changes, the daemon reads it and writes a human-readable .dglwhere file in the same directory.

   You may configure dgamelaunch to show this .dglwhere information using the dgamelaunch extra_info_file option.

   You may also run the crawl-inotify-dglwhere script standalone (without the rest of the dgamelaunch-config setup) by starting it as:

   sudo -u dgl perl crawl-inotify-dglwhere.pl

Note: Some of these commands will probably change names soon.

The ultimate goal for this project is to become a one-stop shop for all your dgamelaunch+Crawl needs, starting from installing dgamelaunch itself

TODO

1. dgl install-dgl command to fetch and install the latest dgamelaunch.

2. dgl create-chroot command to set up a basic chroot jail with all the fixtures dgamelaunch wants (dgamelaunch already has a skeleton script that can serve as a basis, although this is unfortunately NetHack-biased).

3. Support for installing different games, including fetching their sources from their respective source repositories, compiling, installing into the chroot, etc.

   dgl install crawl master`
   dgl install nethack 3.4.3`
   

   Etc.

   Installing a game should also (eventually) add a suitable entry to the various menu files and update the dgamelaunch config appropriately.

4. Support for tracking development versions of games (such as Crawl master) using a system similar to CDO's for creating versioned directories, migrating saves to newer versions, and deleting old versions with no remaining save games.

5. Module system so that management of say, crawl-git is a self-contained module. Each module should be able to contribute dgl commands and provide files that will be installed to the chroot or root filesystem.

6. Each dgl command that affects the machine or chroot should update a manifest. The manifest could be a file or a directory containing multiple manifest files.

   Given a manifest, I should be able to install dgamelaunch-config on a brand new machine and use one dgl command to recreate the manifest.

   For instance, something like: dgl replicate-manifest <path-to-manifest>

   The manifest should include information like this:

   • What dgamelaunch version is installed, and from where (install-dgl module)
   • chroot configuration: what binaries and libraries have been installed into the chroot, with the exception of game binaries, i.e. the state of the chroot minus games (chroot module)
   • Game configuration (handled by the various game modules)
