A library for managing settings
Project description
Settngs
This library is an attempt to merge reading flags/options from the commandline (argparse) and settings from a file (json).
It is a modified argparse inspired by how flake8 loads their settings. Note that this does not attempt to be a drop-in replacement for argparse.
Install with pip
pip install settngs
A trivial example is included at the bottom of settngs.py with the output below (using bash). For a more complete example see ComicTagger.
$ python -m settngs
Hello world
$ python -m settngs --hello lordwelch
Hello lordwelch
$ python -m settngs --hello lordwelch -s
Hello lordwelch
Successfully saved settings to settings.json
$ python -m settngs
Hello lordwelch
$ python -m settngs -v
Hello lordwelch
merged_namespace.values.Example_Group__verbose=True
$ python -m settngs -v -s
Hello lordwelch
Successfully saved settings to settings.json
merged_namespace.values.Example_Group__verbose=True
$ python -m settngs
Hello lordwelch
merged_namespace.values.Example_Group__verbose=True
$ cat >settings.json << EOF
{
"example": {
"hello": "lordwelch",
"verbose": true
},
"persistent": {
"test": false,
"hello": "world"
}
}
EOF
$ python -m settngs --no-verbose
Hello lordwelch
$ python -m settngs --no-verbose -s
Hello lordwelch
Successfully saved settings to settings.json
$ python -m settngs --hello world --no-verbose -s
Hello world
Successfully saved settings to settings.json
$ python -m settngs
Hello world
settngs.json at the end:
{
"Example Group": {
"hello": "world",
"verbose": false
},
"persistent": false,
"hello": "world"
}
What happened to the 'i'?
PyPi wouldn't let me use 'settings'
