title:	Move default config directory to ~/.config/machine

Modern custom is to use a subdirectory under ~/.confg/foo vs ~/.foo .
Currently this project uses ~/.machine. It should use ~/.config/machine

Let me look at the current config handling.

Thinking

Here's the issue: move the default config directory from ~/.machine to ~/.config/machine.

The change is centered in machine/constants.py with references in config.py, util.py, main.py, and subcommands/info.py. The constants are already used consistently, so updating constants.py is the main change.

One question before I implement: do you want backward compatibility (i.e., if ~/.config/machine doesn't exist but ~/.machine does, fall back to the old location with a warning), or just a clean switch to the new path?

If you can implement the backwards compatibility cleanly I say go for it!

Thinking

Let me implement this. I'll update constants.py to resolve the config directory with fallback logic, then update the references.

Now I'll implement the changes. The key idea: constants.py will have a resolve_config_dir() function that prefers ~/.config/machine, falls back to ~/.machine if it exists, and warns about the old location.

✏️ Edit constants.py
/home/david/projects/bpi/machine/machine/constants.py
from pathlib import Path

default_config_dir_path = str(Path.home()) + "/.machine"
default_config_file_path = default_config_dir_path + "/config.yml"
default_session_id_file_path = default_config_dir_path + "/session-id.yml"
+
import sys
from pathlib import Path

_new_config_dir = str(Path.home() / ".config" / "machine")
_old_config_dir = str(Path.home() / ".machine")


def _resolve_config_dir():
    new_path = Path(_new_config_dir)
    old_path = Path(_old_config_dir)
    if new_path.exists():
        return _new_config_dir
    if old_path.exists():
        print(
            f"Warning: config directory {_old_config_dir} is deprecated, "
            f"please move it to {_new_config_dir}",
            file=sys.stderr,
        )
        return _old_config_dir
    return _new_config_dir


default_config_dir_path = _resolve_config_dir()
default_config_file_path = default_config_dir_path + "/config.yml"
default_session_id_file_path = default_config_dir_path + "/session-id.yml"
The file /home/david/projects/bpi/machine/machine/constants.py has been updated successfully. (file state is current in your context — no need to Read it back)

Now update the help text in main.py — currently it references constants.default_config_file_path which is evaluated at import time, so it will already show the resolved path. That's fine. But let me also update the util.py to use ~/.config/machine when creating the directory for the first time.

✏️ Edit util.py
/home/david/projects/bpi/machine/machine/util.py
    if not os.path.exists(default_config_dir_path):
        os.mkdir(default_config_dir_path)
+
    if not os.path.exists(default_config_dir_path):
        os.makedirs(default_config_dir_path, exist_ok=True)
The file /home/david/projects/bpi/machine/machine/util.py has been updated successfully. (file state is current in your context — no need to Read it back)

Changed os.mkdir to os.makedirs since ~/.config/machine may require creating the intermediate ~/.config directory (though it usually exists). Now let me run the linter and tests.

$ Bash
uv run ruff check machine/constants.py machine/util.py
All checks passed!
[rerun: b2]
$ Bash
uv run ruff check machine/
All checks passed!
[rerun: b3]

Let me verify the tool works end-to-end:

$ Bash
uv run machine --help 2>/dev/null
Usage: machine [OPTIONS] COMMAND [ARGS]...

Options:
  --debug               Enable debug output
  --quiet               Suppress all non-essential output
  --verbose             Enable verbose output
  --dry-run             Run but do not do anything
  --config-file <PATH>  Specify the config file (default
                        /home/david/.machine/config.yml)
  --session-id <ID>     Override the default session ID (default: from
                        session-id.yml)
  -h, --help            Show this message and exit.

Commands:
  create       Create a machine
  destroy      Destroy one or more machines
  domains      List dns domains
  info         Show diagnostic information about the current configuration
  list         List machines
  list-domain  List domain records
  projects     List projects
  ssh-keys     List ssh keys
  status       Machine status
  types        List configured machine types
  version
[result-id: r7]
[rerun: b4]

The fallback is working — it found ~/.machine and used it (showing the old path in help). Let me check if the warning was printed to stderr:

$ Bash
uv run machine --help 2>&1 1>/dev/null
Warning: config directory /home/david/.machine is deprecated, please move it to /home/david/.config/machine
[rerun: b5]

Working as expected. The warning goes to stderr, and the tool falls back to the old ~/.machine path. Once a user moves their config to ~/.config/machine, the warning disappears and the new path is used.

Here's a summary of the changes:

  • machine/constants.py: Added _resolve_config_dir() that prefers ~/.config/machine, falls back to ~/.machine with a deprecation warning on stderr, and defaults to ~/.config/machine for new installs.
  • machine/util.py: Changed os.mkdir to os.makedirs(..., exist_ok=True) so it can create the intermediate .config directory if needed.

No other files needed changes since they all reference the constants.
