Algumas tarefas básicas muitas vezes servem para memorizarmos conceitos fundamentais.
Some basic tasks often serve to memorize fundamental concepts.
So, in this article today we will see how to get the current directory in 10 different programming languages. Among them: C++, C, Lua, Java, Bash, JavaScript, Python, PHP, Golang e Ruby.
All were used as simply as possible and in a modern way. It will also serve to review how to concatenate and basic syntax.
In each code there will also be a comment according to the language to compile and/or interpret via the command line.
C++
#include <iostream>
#include <filesystem>
int main(){
std::cout << "The current directory is: "
<< std::filesystem::current_path() << '\n';
return 0;
}
// g++ -std=c++17 current.cpp && ./a.outC
#include <stdio.h>
#include <unistd.h>
#include <limits.h>
int main() {
char cwd[PATH_MAX];
getcwd(cwd, sizeof(cwd));
printf("The current directory is: %s\n", cwd);
return 0;
}
// gcc current.c && ./a.outLua
print("The current directory is: " .. os.getenv("PWD"))
--lua current.luaJava
public class current {
public static void main(String[] args) {
System.out.println("The current directory is: " + System.getProperty("user.dir"));
}
}
// javac current.java && java current Bash
echo "The current directory is: ${PWD}"
# bash current.shJavaScript
console.log("The current directory is: " + process.cwd() )
// node current.jsPython
import os
print("The current directory is: " + os.getcwd())
# python current.pyPHP
<?php echo "The current directory is: " . getcwd() . "\n";
# php current.phpGolang
package main
import (
"fmt"
"os"
)
func main(){
dir,err := os.Getwd() ; _ = err
fmt.Println("The current directory is: " + dir)
}
// go build current.go && ./current Ruby
puts "The current directory is: " + Dir.pwd
