Introduce red test showing problems with multi-files with Interpolation when having NoClobber and NoEnvVars
Philipp-Binder
committed
change FakeEnvVars to EnvVarSnapshot and use it instead of direct access to EnvironmentVariables inside IValue;
Philipp-Binder
committed
make red tests from previous commit green by removing EnvironmentVariable dependencies in the tests where it is possible (check values differently, to be independent from EnvironmentVariables)
Philipp-Binder
committed
move transformations from Parsers to Env (removes the dependency of Parsers to EnvironmentVariables)
Philipp-Binder
committed
move EnvVarSnapshot to Parsers, take partial care of clobbering by prepending results with "not to be clobbered" EnvVars in Env.LoadContents
Philipp-Binder
committed
remove valueAction (former transform Function) from Parsers.ParseDotenvFile by solving the EnvVarSet-Logic completely into Env.LoadContents
Philipp-Binder
committed
introduce "additionalValues" to solve the multi-file problem; makes all tests green;
Philipp-Binder
committed
let Env return only the resulting keyValuePairs --> Env takes responsibility for "NoClobber", but if one needs raw values Parsers.ParseDotEnvFile has to be used directly
Philipp-Binder
committed
rename additionalValues to previousValues and hide them inside Env, making it just an implementationDetail for LoadMulti
Philipp-Binder
committed
rename EnvVarSnapshot to ActualValuesSnapshot; move direct usages from Env inside Parsers;
Philipp-Binder
committed
fix test-declaration and move misplaced comment
