# WIP: Per directory env-variables
|
||
For #86
|
||
|
||
Environment variables are added if you have created a file called .nu inside a whitelisted directory, formatted as shown below. (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.
