duat-filetype

Filetypes for the Duat text editor

This Plugin is included by default, as it is considered a core utility of duat. It adds the two following traits:

• FileType: This trait grants the filetype method, which lets you access the filetype directly. Its implementors are the File widget, String and &str and PathBuf and Path.
• PassFileType: This trait also has a filetype method, but it requires a Pass, bypassing the need to, for example, read a Handle<File<Ui>, Ui>. Its implementors are RwData<File<Ui>>, Handle<File<Ui>, Ui>, FileHandle<Ui> and FileBuilder<Ui>, from the OnFileOpen hook.

Both of these traits are included by default in Duat’s prelude, but if you want to use them in a plugin, first, add duat-filetype to the dependencies:

cargo add duat-filetype

Or, for latest git version:

cargo add --git https://github.com/AhoyISki/duat-filetype

Then, just use it in the file:

use duat_filetype::FileType;

fn is_toml(file_name: &str) -> bool {
    file_name.filetype() == Some("toml")
}
