TasksScheduler

TasksScheduler is a system which runs scheduled tasks by using a cron-like pattern

Description

TasksScheduler automatically executes scheduled tasks. The system loads tasks from a CSV file and executes them automatically when scheduled. The tasks are executed sequentially and also supports simultaneous executions by using a multithreaded architecture.

Task -

struct Task {
    std::string command;
    cron::cronexpr cron_expression;
    std::time_t next_execution;
};

The CSV file has 4 columns which represent the command and the time in which it needs to be executed.

CSV file structure:

minute	hour	day_of_week	command
24	4	2	task1
57	17	5	task2
11	20	0	task3

Example
