PathBuf Macro

A macro for ergonomic and safe construction of file and directory paths in Rust, with context-aware resolution.

• Supports both string literals and formatted paths with arguments.
• Automatically determines whether to allow a path relative to the current working directory, the executable directory, or the user data directory.

P.S. More useful macros are available in the macron package.

Features:

• Empty call: path!() returns PathBuf::new().
• Executable prefix $: path!("$") → std::env::current_exe().
• Executable directory $/: path!("$/foo/bar") → current_exe().parent().join("foo/bar").
• Home directory ~/: path!("~/foo/bar") → $HOME/foo/bar (USERPROFILE on Windows).
• User data directory %/:

  OS	Default Directory
  Windows	C:/Users/User/AppData/Roaming/
  macOS	~/Library/Application Support/
  Linux	~/.local/share

• Formatting: path!("foo/{arg1}/{}", arg2).
• Expressions: path!(some_path_var).
• Plain paths: path!("foo/bar").

Examples:

use macron_path::path;

// empty PathBuf:
let empty = path!();

// plain path (relative to CWD):
let relative = path!("foo/bar");

// executable path:
let exe_path = path!("$");

// executable directory:
let exe_dir_path = path!("$/config.toml");

// home directory:
let home_path = path!("~/Documents/file.txt");

// user data directory:
let data_path = path!("%/myapp/settings.json");

// formatting:
let user_path = path!("users/{}/docs", "alice");
let dynamic = path!("dir/{}", some_var.to_string());
