⏱️ Scheduler

An easy to use c++ library for scheduling tasks.

Summary

• Installation
• Example

Installation

• Getting the library from source:

git clone https://github.com/joaovictorjs/scheduler

• Setup and compile (meson required):

cd scheduler &&
meson setup --prefix=/usr --buildtype=release build &&
meson compile -C build

• Test the code (optional):

meson test -C build

• Finally, install the library:

meson install -C build

Example

Purpose: create a software that will print each 5 seconds to console "Hello, i'm a scheduled task. Now is [actual datetime]" until 2100-01-01 00:00:00.

• File: meson.build

project('scheduler-example', 'cpp')

executable(
	'scheduler-example', 
	sources: 'main.cpp', 
	dependencies: dependency('scheduler')
)

• File: main.cpp

#include <iomanip>
#include <iostream>
#include <scheduler.hpp>

void print_hello();

int main() {
	Scheduler::Task task;
	
 task.set_interval(5)
		.set_datetime_start("2000-01-01 00:00:00")
		.set_datetime_end("2100-01-01 00:00:00")
		.run(print_hello);
 
 return 0;
}

void print_hello() {
	std::time_t now {std::time(nullptr)};
	std::tm* now_tm {std::localtime(&now)};
	std::cout<<"Hello, i'm a scheduled task. Now is "<<std::put_time(now_tm, "%Y-%m-%d %H:%M:%S")<<'\n';
}

• Setup and compile (meson required):

meson setup build && meson compile -C build

• Running:

./build/scheduler-example
