We do need no bloated gtk-redshift do we?

wow.

[ivanovnegro]

Just wow. That is so awesome Jules. One thing, how about adjusting it when you watch videos, I mean, to disable it. I am not a bash perfectionist.

[machinebacon]

start it again and press q - this resets it.

[ivanovnegro]

Ok, that sounds logical.

[rhowaldt]

that is cool! well done :)

[dkeg]

I saw this before work today. Really great. I love the direction we've been posing going. Very creative, smart, and fuck you'ish.

Edit-stupid auto correct typo

[ChefIronBelly]

Just what my eyes need thanks.

[GekkoP]

This will be useful, thanks!

Seems like a case statement would be a better choice.

Great idea though, I never thought it could be done

[machinebacon]

^ Originally I only wanted to shift red. Then I simply added the other colors. If you don't like it, please ignore :)

I modified this script to have limits to the gamma passed to xrandr, so that we won't get unexpected behaviour.

Also did some refactoring.

Note that the limits are exclusive (that means if you set MIN to 0, you can't set the gamma to 0 or below, and likewise for MAX).

Code: Select all

#!/bin/bash
RR=1
GG=1
BB=1
LL=1

NR=1
NG=1
NB=1
NL=1

MIN=0 # min gamma
MAX=200 # max gamma

CON=`xrandr -q | grep con | cut -d " " -f 1 | xargs`
echo "Detected connectors are: $CON"
echo "Which do you want to manipulate?"

inc_gamma() {
  let "VAL = $1 + 5"
  if (( "$VAL" < "$MAX" )); then
    set_val $2 $VAL
    echo "$2 increased to $VAL"
  else
    echo "$2 cannot be increased above or to $MAX."
  fi
}

dec_gamma() {
  let "VAL = $1 - 5"
  if (( "$VAL" > "$MIN" )); then
    set_val $2 $VAL

If possible it'd be great if we could eliminate the conversion from integers to floats and instead directly modify these values as floats.

[rhowaldt]

^ cool, thanks :)
