muted red would be reasonable. Even better would be an automatic weighted average of borderNormal and borderFocussed (as the default). This would require something like:
data WNConfig = WNC { showNavigable :: Bool , averageFocusAndNormal :: Double [...]
Note that this average idea could be tricky. If both colors are of the form "#00ff00", then it's easy, we convert to three Ints and back. Otherwise, I think we'd have to involve X to compute the color values, and I'm not sure how to do that.
I don't thin I've already understood this weighted average stuff but it sounds cool and I'll try to implement it. Actually I'm going to put it on my TODO list... the best I can do right now.
My idea is that if we can write functions like redComponent :: Color -> Double -- ranges from zero to one greenComponent :: Color -> Double -- ranges from zero to one blueComponent :: Color -> Double -- ranges from zero to one newColor :: Double -> Double -> Double -> X Color -- rgb then we could do something like: do fc <- asks focusedBorder nc <- asks normalBorder let f = max 1 $ min 0 $ frac n = 1 - f combine comp = f*(comp fc) + n*(comp nc) defaultBorder <- newColor (combine redComponent) (combine greenComponent) (combine blueComponent) But I'm not sure how to extract the components of a color. Constructing a new color with given components seems relatively easy, just by printing the values out as a hex string.
I was also thinking that a couple of exported WNConfigs would be handy:
The rest of you requests seem very useful to me to and I'm going to send a patch soon.
That'd be great! -- David Roundy Department of Physics Oregon State University
