std/path

std/path provides portable path manipulation. Use it with std/fs for file operations.

API

pub ext fun parent(path: String) String;
pub ext fun basename(path: String) String;

pub fun join(a: String, b: String) String;

Function	Description
join(a, b)	Joins two path segments with the correct separator
basename(path)	Returns the last component of the path (filename)
parent(path)	Returns the directory containing the path

Examples

Basic path operations

import "std/path";
import "std/io" { println };

fun main() Int {
    var file: String = path.join("/home/user", "docs/notes.txt");
    println(file);                   // "/home/user/docs/notes.txt"
    println(path.basename(file));    // "notes.txt"
    println(path.parent(file));      // "/home/user/docs"
    return 0;
}

Building paths dynamically

import "std/path";
import "std/fs";
import "std/io" { println };

fun main() Int {
    var base: String = "/tmp";
    var project: String = path.join(base, "myproject");
    var src: String = path.join(project, "main.zp");
    var out: String = path.join(project, "build");

    println(src);   // "/tmp/myproject/main.zp"
    println(out);   // "/tmp/myproject/build"

    println(path.basename(src));  // "main.zp"
    println(path.parent(src));    // "/tmp/myproject"

    return 0;
}
