title: Move default config directory to ~/.config/machine state: OPEN author: dboreham labels: comments: 0 assignees: projects: milestone: number: 80 -- Modern custom is to use a subdirectory under ~/.confg/foo vs ~/.foo . Currently this project uses ~/.machine. It should use ~/.config/machine [result-id: r1] [rerun: b1]

[result-id: r5]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?
Let me implement this. I'll update constants.py to resolve the config directory with fallback logic, then update the references.

[result-id: r6]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.
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.
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.
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:
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.
