Features

In v1.0.0 and above, the code has been divided into features due to growing functionality. The features are listed below:

• Creation: This feature is kind of a default feature as this allows users to create a RPath struct from these -> [String, &str, Path, PathBuf].
• Management: This feature will be enabled by default and contains methods to manage/manipulate paths.
• Conversion: This feature contains all conversion methods from RPath to different path types.
• Boolean: This feature contains all boolean type methods for checks.
• pyo3-bindings: This feature is by default disabled. It can be used to return RPath to python which will be automatically converted to string. Full Details here.

Usage

• Importing

  use rustypath::RPath; // for all basic functionalities.

  Note: Implementation includes -> [Clone, Debug, PartialEq, Eq, PartialOrd, Ord, Hash] and a custom trait for printing RPath.

  // for printing the path as it is, `Display` trait can be imported.
  use rustypath::Display;

• Creating RPath

  • From &str, Path and PathBuf

    // to create a RPath
    let rpath_str = RPath::from(value);
    
    // NOTE: value can be of type &str, Path (std::path::Path) or PathBuf (std::path::PathBuf)
    
    // Examples:
    let rpath = RPath::from("/temp");
    let rpath_ = RPath::from(std::path::Path::new("/temp"));
    let rpath__ = RPath::from(std::path::PathBuf::from("/temp"));

  • Allocate an empty RPath

    let rpath_empty_or_new = RPath::new();
    // this will allocate an empty RPath

• Path Manipulation

  • Join

    // make a RPath
    let rpath = RPath::from("/temp");
    
    // add childs to it,
    let new = rpath.join("abc.txt");
    new.print();
    // this will print "/temp/abc.txt"

  • Join Multiple

    // make a RPath
    let mut rpath = RPath::from("/temp");
    
    // suppose you want to add multiple components to the path
    rpath.join_multiple(vec![value1, value2, ...]);
    // here value1, value2 can be any of these types => [&str, Path, or PathBuf]
    rpath.print();
    // this will print -> "/temp/value1/value2/..."

  • Basename/Filename

    // to get the basename or filename of the path:
    let rpath: Rpath = RPath::from("/temp/abc.txt");
    let basename: &str = rpath.basename();

  • Replace Basename

    // suppose there's a RPath -> "/temp/abc.txt" and
    // you want to just replace "abc.txt" with "xyz.txt" without
    // typing whole new full paths or rel paths, and just update using
    // the existing one.
    
    let rpath = RPath::from("/temp/abc.txt");
    let rpath_ = rpath.with_basename("xyz.txt"); // this will be "/temp/xyz.txt" 

  • Dirname/Parent

    let rpath: RPath = RPath::from("/temp/abc.txt");
    
    // to get the parent
    let parent: RPath = rpath.dirname(); // this will be "/temp"

  • Replace Dirname/Parent

    // suppose there's a RPath -> "/temp/abc.txt" and
    // you want to replace "/temp" with something else
    
    let rpath: RPath = RPath::from("/temp/abc.txt");
    let new = rpath.with_dirname("/temp/temp2"); // this will make it -> "/temp/temp2/abc.txt"

  • Extention

    // to get the extension of a file from the RPath
    let rpath = RPath::from("/temp/abc.txt");
    
    let extension: &str = rpath.extension();
    // NOTE: this will return either extension (if present) or the basename.
    // if path is invalid it will print error and exit.

  • Expand

    let rpath = RPath::from("./temp");
    let expanded = rpath.expand(); // this will expand if not full path, else it wont throw error.
    // remeber that it will only expand the path if the path exits
    // if "./temp" directory doesnt exist it will return "./temp"

  • Read_Dir (return an iterator with DirEntry)

    let rpath = RPath::from("/temp");
    
    for entry in rpath.read_dir().expect("Failed to call read_dir") {
        if let Ok(entry) = entry {
            println!("{:?}", entry.path());
        }
    }

  • Get Current Working Directory

    let current_dr: RPath = RPath::pwd();

  • Get Home dir of your OS

    let home: RPath = RPath::gethomedir();

  • Clear the current RPath buffer

    let rpath = RPath::from("/temp");
    rpath.clear(); // this will be equivalent to RPath::new();

• Conversion

  • Convert to string

    let rpath = RPath::from("/abc");
    let rpath_string = rpath.convert_to_string();

  • Convert to PathBuf

    let rpath = RPath::from("/abc");
    let rpath_in_pathbuf = rpath.convert_to_pathbuf();

• Boolean

  • exists

    let rpath = RPath::from("/abc");
    if rpath.exists() {
        // do something
    }

  • is_dir/is_file

    let rpath = RPath::from("/abc");
    
    if rpath.is_dir() {
        // do something
    } else if rpath.is_file() {
        // do something
    }

  Similarly, the following will work:

  • is_absolute

  • is_symlink

  • is_relative

  Extras:

  • if_extension

    let rpath = RPath::from("/abc.txt");
    
    if rpath.if_extension("txt") {
      println!("The file is a text file!");
    }

• Printing

  RPath supports printing as a single string.

  To use the .print() function, import Display trait

  use rustypath::Display;

  Printing using .print() method.

  let rpath = RPath::gethomedir();
  rpath.print();
  // this will print `homedir` path in a single line.

  To print with other strings:

  let rpath = RPath::gethomedir();
  
  println!("Homedir: {}", rpath.convert_to_string());
  println!("{:?}", rpath);

• Operators

  • Supports == and != operators

    let rpath = RPath::pwd();
    let rpath_ = RPath::gethomedir();
    
    if rpath == rpath_ {
        // do something
    } else {
        // do something else
    }

• Supports Hash

pyo3-bindings

Lets understand by an example.

You are using rustypath::RPath to manage all your paths but when creating Python/Rust Mix projects, you also want it to be easier to return RPath to python? right?. Say No more!

use pyo3::prelude::*;
use rustypath::RPath;

#[pyfunction]
fn demo(dir: &str) -> PyResult<RPath> { // see that I am returning RPath, which is not supported by python.
  let new = RPath::from(dir);

  Ok(new) // this will work fine and will return a string.
}

// similarly while returning Vec<RPath>, it will return a list of strings.
