Hello Haikarainen,
Nice work there, but I am having some issues
1. The script needs root privileges now . ( is that what you intended ? if so i am ok with it )
2. When decreasing brightness, at some point when the script reaches to the lowest value , it again starts with the max brightness , this was not the case with the previous version of the script.

Apart from these little issues, your script works exactly the way it should.

Thanks for your feedback..

1. I'm working on it, currently trying to figure out how to create udev rules for permissions as an alternative to the auto-sudo thingy(which is harder now since its an executable).

2. Ah crap, I thought I had this fixed. I noticed it in development. It's an unsigned integer in C89 that underflows. I will look this up and make sure it cannot happen. It is actually the only FIXME in the source atm xD

Also it isnt a script anymore

I have a small suggestion for your program. I have noticed some weird behavior. Whenever I do light --help. it returns the current brightness. The expected behavior for both --help and -h should be the output when light is ran without arguments. You can easely do this with getops.
I also have the same problems with root.

Oh..my bad . It is a program now. You should consider changing the thread title too.
And about udev you may try

 MODE="666"

in udev rule, I am no expert but saw something like this a while back.

That is REALLY weird. I have custom code to parse arguments, of course --help and -h should show usage.. Will put this in the next commit.

Regarding root: Still working on this.

EDIT: It's not really that weird, since I havent implemented --args yet it basically parses is as tags: "-", "h", "e", "l", "p". p is the tag for precise current brightness. Fixing this now

Thanks, appreciate the feedback! I thought about that myself, but I found 3 different places to post this on the forum (1 was the contributions, 1 here, and 1 in the sticky for small programs). We'll see what the mods think, hopefully they have mercy upon my soul and doesn't delete the whole post.

*twiddles thumbs*

Better late than never.

Moving from Programming & Scripting to Community Contributions.

If you want to open a new thread for your C port, you know where to.
