New version of Light (control your laptops backlight easily).

Haikarainen · 2014-07-05 21:17:42

This is a complete rewrite of my old pet project, as I felt the need to severely clean up the code. See the old thread here: https://bbs.archlinux.org/viewtopic.php?id=153210

Anyway, new version, completely new command line usage -- sorry, it was pretty much inevitable. More complete functionality as well: no more hacking when you want to set minimal brightness or specify a controller, it's all done in command line now. It's also installed with root capabilities directly, so no more hacking with that either. Just makepkg -si and off you go!

If you face any problems, don't forget to run it with the verbosity flag, -v 3, to get all the errors! You will probably get a lot of errors (if you get one), they are there to make it easier to trace the problem in code (you pretty much get a stack).

I want to make it clear that the changes to the command line usage was done for several good reasons, including the fact that it wasn't very intuitive before.

Github: https://github.com/haikarainen/light

UPDATE:

* The AUR package has been split up in 2, https://aur.archlinux.org/packages/light/ and https://aur.archlinux.org/packages/light-git/ .
* It also has an official website now (thanks to github): http://haikarainen.github.io/light/
* Even more functionality
* There are deb packages available.

Any feedback appreciated!

Here is an updated version (for pacman 4.1) of your PKGBUILD:

pkgname=light
pkgver=20140705
pkgrel=2
pkgdesc='Program to easily change brightness on backlight-controllers.'
arch=('any')
url="https://github.com/haikarainen/$pkgname"
license=('GPL3')
makedepends=('git')
conflicts=('lightscript')
provides=('lightscript')
replaces=('lightscript')
source=('git+https://github.com/haikarainen/light.git')
md5sums=('SKIP')

build() {
  cd "$srcdir/$pkgname"
  make
}

package() {
  install -d "$pkgdir/etc/light/mincap"

  install -Dm755 "$srcdir/$pkgname/light" "$pkgdir/usr/bin/light"
  install -Dm644 "$srcdir/$pkgname/LICENSE" "$pkgdir/etc/light/LICENSE"
  install -Dm644 "$srcdir/$pkgname/README" "$pkgdir/etc/light/README"
  install -Dm644 "$srcdir/$pkgname/CHANGELOG" "$pkgdir/etc/light/CHANGELOG"

  chmod a+s "$pkgdir/usr/bin/light"
}

I also believe it would be a good idea to move the doc files (LICENSE, etc) to /usr/share/light, or even /usr/share/doc/light, but I haven't changed this.

Thanks a ton for your response! Will take a look at the PKGBUILD (and AUR package process) when I have time and modernize it / make it proper!

mariojuniorjp · 2014-07-07 15:34:59

Thank you very much for this application. \o/

The PKGBUILD needs more help than that. It's pulling from git master, so it should be called light-git and include a pkgver function.

If you don't want a -git package, than release a new version, e.g. create a version number tag v0.9.2 and add #tag=v0.9.2 to the git url.
You could also reference a certain git commit with commit=COMMITID, but that feels a bit unnatural when you are the owner of the git repository. This is something I'd only do if there were important bugfixes without a new version tag in the repo.

Ah thanks for this, I just tagged versions on git 15 mins ago (or something), this seems like the best bet.

Sorry about the PKGBUILD, I haven't made one in almost 2 years and that one was the first I ever did so.. I appreciate all your feedback and help!

No need to be sorry, all tips here are meant to improve your application. Keep up the good work

Haikarainen · 2014-07-10 20:05:26

Thanks a ton for your feedback and help, I have now created 2 packages instead;

light-git for latest master: https://aur.archlinux.org/packages/light-git/

light for latest tagged version: https://aur.archlinux.org/packages/light/

Also don't miss out on my latest commits; tons of small improvements(including proper makefile) and 2 added features; List controllers with -L, and save/restore your brightness (for reboots etc) with -I and -O

Haikarainen · 2014-07-11 11:06:12

Just gave the wiki a well needed update as well; https://wiki.archlinux.org/index.php/Light

Haikarainen · 2014-07-14 21:35:26

UPDATE: There are now debian packages available, more functionality and fixes, better documentation etc.

Nordic89 · 2014-08-05 21:02:59

Did you think about the possibility of automatically changing the brightness depending on an ambient light sensor?

erno · 2014-08-15 12:30:02

have you considered adding some colour temperature adjustments? atm redshift does that for me but it isn't very good at setting the backlight...would be great not having to use 2 programs for this.

When I try to install(with pacaur), this error appears:

Any ideas?

Edit:Not light problem. Apparently my gcc install is having some problems. Disregard this.
