Installation

pip install maplocal

Configuration

to configure maplocal the following env vars must be set:

MAPLOCAL_OS_FROM: str = "linux"  #  TODO make enum
MAPLOCAL_OS_TO: str = "windows"  #  TODO make enum
MAPLOCAL_FROM: ty.Optional[pathlib.PurePath] = None  # the rootdir to be removed from path
MAPLOCAL_TO: ty.Optional[pathlib.PurePath] = None  # the rootdir to be added to path
MAPLOCAL_SCRIPT_PATH: ty.Optional[pathlib.Path] = None  # script with `openpath` and `runcmd` functions

in the MAPLOCAL_SCRIPT_PATH dir is a python file that must contain functions named openpath and runcmd.

Use Case

You manage a cloud-hosted service that is attached to file-server storing user data. Users have access to your service, but also separately have access to file-directory through their computers. The way that the file-server is mounted is different for the user and for the cloud hosted service. This provides a way to map the root directory of the users machine and the file server. It also provides a hacky, potentially unsafe[1][1] hook that allows a locally saved script file to inject the functions openfile and runcmd that are intended to provide ways for the server to open a file from the users machine and run a shell command on the users machine.

[1]: a script file placed in a known directory allows users to inject code into the program. Not inherently unsafe but could be used as a way to inject malicious code by bad-actors.

Examples

1. running WSL, Ubuntu. Opening files saved in the Ubuntu file system with Windows Programs.
2. running WSL, Ubuntu. Opening files on the windows files system (mounted C:\drive).
