A package that uses external configuration files to generate a static, standalone parser module.
Add parsers aside from toml, like json and configparser.
Allow import of third-party libraries, like toml, to fail-just remove that format from the valid list.
Given a configuration like:
# Quickly define '--help', '-h', and '-x'
[help]
number = 0
alternatives = ['h', 'x']
# Immediately raise an error if too few values given.
[range]
number = 2
# Take variable numbers of values, only raising an error at the minimum.
# Will greedily consume arguments up to the maximum.
[files]
minimum = 1
maximum = 9
You could include the following in your build process:
python -m gap my-project-cli.conf > cli.py
Your argument parser then is accessible in Python like:
import sys, cli
options, positionals = cli.main(sys.argv[1:])
if "help" in options.keys():
print_help_message()
# It's just a built-in dict, so use all the usual methods as you please.
for file in options.get("files", []):
read_input(file)
else:
for argument in positionals:
read_input(file)
