Make a plugin to change server.properties ingame

Hi bukkit,
Can someone make me a plugin which gives the possibility to change server.properties values ingame without reboot. something as:
/properties <property> <value>
and a permission named: properties.<property>.
Example: Admin1 wants to change the value pvp to true he needs to type /properties pvp true and he needs the permission node properties.pvp

and a command: /properties view to view the server.properties file ingame (permission name: properties.view)
Thanks Tzzzt123

Hi bukkit,
me again. And if someone wants he can make an addon that can change the values of standard .yml files (bukkit.yml, commands.yml, help.yml, permissions.yml [Not permissions plugin], [And for spigot users spigot.yml]). The command could be /yml <file_without.yml> <part_of_yml> <add_under/remove_under/change> <value>
and permission node: yml.<file_without.yml>.<part_of_yml>
Example:
If Admin1 is online again and types: /yml commands command-block-overrides add_under heal he would need this permission node: yml.commands.command-block-overrides and then it changes this:

YML (open) YML (close)

command-block-overrides:
- heal

If you need additional information write it in this thread!
Thanks Tzzzt123

@timtower that is just an idea for plugin developers who want to make a plugin. if anyone wants, he can make this plugin.

Prety sure it is not possible to edit this file using a plugin. The plugin has no access to the server properties file since it is a read-only file. Also, your plugin doesn't have access to that folder. Would be very vulnurable tough if it was possible.

 

@MrGeneralQ
I am able to write to it. Might be because it is on my Computer though. Crude example code would be this:

Code:

        Path path = Paths.get(getDataFolder().getParentFile().getAbsolutePath()).getParent().resolve("server.properties");
        try {
            List<String> lines = Files.readAllLines(path);
            lines.add("test:test");
            Files.write(path, lines, StandardOpenOption.TRUNCATE_EXISTING);
        } catch (IOException e) {
            e.printStackTrace();
        }

Just put it in the onEnable, and it will append "test:test" to the file.

But the point is what timtower already mentioned. You would need to reload the server "Bukkit#reload" and if you do this, you can cause problems with other plugins. I also don't know if just reloading is enough to refresh the settings or if you need to restart it.
