(I am, of course, open to change everything about this) +``` +#inside a .nu-file in a whitelisted directory +[env] +var = "value" +anothervar = "anothervalue" +``` + +In order for a .nu-file to be read, the directory it is in must be listed in the `nu_env_dirs` variable in nushell's `config.toml`. +``` +nu_env_dirs = ["/home/sam", "/home/sam/github", "/home/sam/github/test"] +``` + +# The way it works now is that whenever you run the function `maintain_nurc_environment_vars`, the current directory is checked for a `.nu` file and if it exists the variables in it are added. This works. +# Of course, when you leave a directory the variables should be unset. I track this by having a map between directory and a vector of environment variables. If the user is not in the directory or one of its subdirectories, its environment variables are removed... And then for some reason they are re-added again? + +Behavior: +- If you are in a subdirectory to a directory with a .nu-file, the vars in that .nu-file are applied. +- If you leave a directory which set some variables, the variables are unset. +- If a directory contains a .nu with an environment variable already set, the old value will be overwritten with the value from the .nu. This holds even if the old value was set by a .nu in a parent directory. + - The overwritten value is restored when you leave the directory. + - TODO: What happens if you overwrite twice? + +Questions: +- ´add_env´ does not overwrite variables. Need ´add_env_force´? +- `ctx.get_env()` in `cli.rs` lacks access to the config, which is required. Is it ok to do it through the sync call instead? + +TODO: take care of situation where a directory overwrites an existing .nu conf. + +---- + +# \ No newline at end of file
