Nix Generator Functions for Sway

A short & sweet post on using the Nix language to generate Sway config 🥝
I don't tend to use Linux on the desktop at the moment and figured it'd be a shame not to share these
functions I wrote to generate input & output blocks.
toSwayInputs
Convert a set representing Sway input expressions to valid sway config.
Usage
toSwayinputs inputs
Expression
toSwayInputs = inputs:
concatStringsSep "\n" (
mapAttrsToList (device: config: ''
input "${device}" {
${concatStringsSep "\n " (
mapAttrsToList (p: v: "${p} ${v}") config
)}
}
'') inputs
);Example input
inputs = {
"1:1:AT_Translated_Set_2_keyboard" = {
xkb_layout = "gb";
xkb_options = "ctrl:nocaps";
};
"1739:0:Synaptics_TM3381-002" = {
pointer_accel = "0.7";
tap = "enabled";
dwt = "enabled";
natural_scroll = "enabled";
};
};
toSwayOutputs
Convert a list of sets representing Sway output expressions to valid kanshi config.
Usage
toSwayOutputs outputs
Expression
toSwayOutputs = outputs:
concatStringsSep "\n" (
forEach outputs (block: ''
{
${concatStringsSep "\n " (
mapAttrsToList (display: config:
"output ${display} ${concatStringsSep " "
(mapAttrsToList (p: v: "${p} ${v}") config)}"
) block)
}
}'' )
);Example input
outputs = [
{ eDP1 = {};}
{
"DP-1" = {
position = "0,0";
transform = "270";
};
"HDMI-A-2" = { position = "1440,470"; };
"eDP-1" = { position = "1440,1910"; };
}
