File Path 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

• Relative to current working directory: If the path does not start with / or , it is resolved relative to the current working directory (std::env::current_dir()).
• Relative to executable's directory: If the path starts with / or , it is resolved relative to the directory where the executable resides (std::env::current_exe()).
• Supports formatting: You can use string formatting just like with the standard format! macro.

Examples:

use macron_path::path;

// Path relative to the current working directory
let relative_path = path!("foo/bar");

// Path relative to the executable's directory
let root_path = path!("/foo/bar");

// Path relative to the user data directory for saving applications data
let root_path = path!("$/foo/bar");

// Supports string formatting
let fmt_path = path!("foo/{}", "bar");

Notes:

• Windows: Both / and \ are supported as path separators.

• Linux/macOS: Only / is treated as a directory separator. For best results, use / or build paths using the macro or standard library methods.

• Always use the path!: macro to avoid issues with separators and path resolution differences across platforms.
