# Util

The `Scar::Util` module provides some useful methods.

### File Handling

These methods are supposed to help writing files to a local user directory.

Before using any of them, set the subdirectory inside the user directory (windows: `%appdata%\<subdir>` | linux: `~/.local/share/<dir>`) by calling `Scar::Util.dir = <dir>`.

After that, you can write and read files with the following methods:

* `write_file(name : String, content : String)`
* `write_file_bytes(name : String, content : Bytes)`
* `read_file(name) => String`
* `read_file_bytes(name) => Bytes`
