# runtime.path

When using `require`, how to find the file based on the input name.
Setting this config to `?/init.lua` means that when you enter `require 'myfile'`, `${workspace}/myfile/init.lua` will be searched from the loaded files.
if `runtime.pathStrict` is `false`, `${workspace}/**/myfile/init.lua` will also be searched.
If you want to load files outside the workspace, you need to set `Lua.workspace.library` first.


## type

```ts
Array<string>
```

## default

```jsonc
["?.lua","?/init.lua"]
```

When enabled, `runtime.path` will only search the first level of directories, see the description of `runtime.path`.
