to. So in some cases `POWERLEVEL9K_SHORTEN_DIR_LENGTH` means characters, in
others whole directories.
The `truncate_with_package_name` strategy gives your directory path relative to the root of your project. For example, if you have a project inside `$HOME/projects/my-project` with a `package.json` that looks like:
```json
{
"name": "my-cool-project"
}
```
the path shown would be `my-cool-project`. If you navigate to `$HOME/projects/my-project/src`, then the path shown would be `my-cool-project/src`. Please note that this currently looks for `.git` directory to determine the root of the project.
