SimpleCron

A dumbed down cron done in c#, no need to install
Works on Windows (x64 and x86) and Unix-like systems (x64).

Just run it. It will use any json or yaml(.yml & .yaml), except for commands_template.json commands_template.yml and commands_template.yaml, placed inside the folder the exe is placed in, or any of it's subfolders. You can rename, delete, add or modify files on the fly and the program will know what to do, no need to restart it.

A json file could be:

{
  "command_type":"timer",
  "repeat_after":{
    "days":1,
    "hours":5,
    "seconds":300
  },
  "commands": [
    "notepad hello_world.txt",
    "code"
    ]
}

Or

{
  "command_type":"cron",
  "cron_expression":"0 */3 * ? * *",
  "commands":[
    "code",
    "notepad"
  ]
}

The same examples in yaml would be:

---
command_type: timer
repeat_after:
  days: 1
  hours: 5
  seconds: 300
commands:
- notepad hello_world.txt
- code

And

---
command_type: cron
cron_expression: 0 */3 * ? * *
commands:
- code
- notepad

The file must have a commands list, as seen on the commands_template files.
By default, the task will be treated as if it's "command_type" was a timer. And as if the timer was set to repeat after 5 minutes have passed.

If you wish to use a cron expression, just use "command_type": "cron" and "cron_expression":$your_expression as seen in the example above. Should there be any problem with the expression, the file will be ignored.
