Macro fs_tree::tree

macro_rules! tree {
    ($($all:tt)+) => { ... };
}

Macro for declaring a FsTree literal.

Syntax:

• name is a regular file.
• name: { ... } is a directory.
• name -> name is a symlink.
• Commas are (unfortunately) not supported.
• Use quotes ("name") for spaces, dots, etc.

Examples:

use fs_tree::{FsTree, tree, TrieMap};

let result = tree! {
    file1
    outer_dir: {
        file2
        inner_dir: {
            file3
        }
        link1 -> target
        link2 -> "/home/username/.gitconfig"
    }
};

let expected = FsTree::Directory(TrieMap::from([
    ("file1".into(), FsTree::Regular),
    ("outer_dir".into(), FsTree::Directory(TrieMap::from([
        ("file2".into(), FsTree::Regular),
        ("inner_dir".into(), FsTree::Directory(TrieMap::from([
            ("file3".into(), FsTree::Regular),
        ]))),
        ("link1".into(), FsTree::Symlink("target".into())),
        ("link2".into(), FsTree::Symlink("/home/username/.gitconfig".into())),
    ]))),
]));

assert_eq!(result, expected);
