I got the following minimal example working but presumably my solution
isn't the best way.
xtoml.py:
class Xtoml:
def __init__(self, which='rtoml'):
self.which = which
def parse_toml(self, toml_string):
if self.which == 'rtoml':
import rtoml as toml
elif self.which == 'tomlkit':
import tomlkit as toml
else:
import toml
return toml.loads(toml_string)
test_xtoml.py:
from xtoml import Xtoml
toml_string = """
[default]
basedir = "/myproject"
"""
def main():
xtoml = Xtoml('toml')
parsed_toml = xtoml.parse_toml(toml_string)
print(parsed_toml)
xtoml = Xtoml()
parsed_toml = xtoml.parse_toml(toml_string)
print(parsed_toml)
if __name__ == "__main__":
main()
