The MMGen Project
c7adb56e38
This patch eliminates the global configuration variables `opt` and `g`, making all functions and class instances locally configurable. Configuration data is passed to functions and constructors via the `cfg` parameter and made available to methods in `self.cfg`. Local configuration free from dependence on the command line will enable the creation of multiple, independently configured instances of MMGen’s data objects within a single process. Potential applications include testing (tracking wallets configured to interact with spawned processes, for example) and the use of MMGen as a library for other projects. This patch completes most of the work required to enable the API. The full implementation will appear in a forthcoming commit.
