I have a script which I use to toggle between dark/light mode a few times a day using I'd like to avoid using subprocess to listen on events from gsettings in lite-xl. I looked at some of the code for lite-xl but I'm not a programmer and I'm guaranteed to miss something. |

Why? That would probably be the simplest way.
Not really. But you could use the If the script is purely time-based, you could replicate it as a Lite XL plugin. If this is about the same toggle that directs https://wiki.libsdl.org/SDL3/SDL_GetSystemTheme, when we port to SDL3 we'll add a listener for that. |

For anyone interested, here is my solution. -- mod-version:3
local core = require "core"
local gsettings = process.start({
"sh", "-c",
"gsettings get org.gnome.desktop.interface color-scheme;" ..
"gsettings monitor org.gnome.desktop.interface color-scheme"
})
core.add_thread(function()
while gsettings:running() do
local color_scheme = gsettings:read_stdout()
if string.find(color_scheme, "default") then
core.reload_module("colors.summer")
elseif string.find(color_scheme, "dark") then
core.reload_module("colors.default")
end
coroutine.yield(1)
end
end) |

Oh this looks great! A little warning: -- mod-version:3
local core = require "core"
local gsettings = process.start({
"sh", "-c",
"gsettings get org.gnome.desktop.interface color-scheme;" ..
"gsettings monitor org.gnome.desktop.interface color-scheme"
})
if not gsettings then
-- Not really correct, as we're directly running sh, not gsettings
error("Could not start gsettings. Is it installed?")
end
local function parse_output(s)
if string.find(s, "default") then
core.reload_module("colors.summer")
elseif string.find(s, "dark") then
core.reload_module("colors.default")
end
end
core.add_thread(function()
local output = ""
while true do
local buf = gsettings:read_stdout()
if not buf then break end
if #buf > 0 then
output = output .. buf
repeat
local line, remainder = string.match(output, "(.-)\n(.*)")
if line then
output = remainder
parse_output(line)
end
until not line
end
coroutine.yield(.250)
end
core.warn("gsettings process died")
end)which will deal with partial outputs and quick theme changes (for example by double clicking the theme button). This could become a proper plugin! Feel free to PR it in the plugins repo. |

Thank you for your input!! Yes, this solves the problem of consecutive theme changes. Better leave this feature for SDL3 to handle. |

For those on macOS, here's a (less efficient) version of the plugin quickly adapted to work on the platform: -- mod-version:3
local core = require "core"
local defaults = process.start({
"sh", "-c",
"while true; do defaults read -g AppleInterfaceStyle > /dev/null; echo $?; sleep 1; done"
})
if not defaults then
error("Could not start defaults loop")
end
local function parse_output(s)
if string.find(s, "1") then
core.reload_module("colors.everforest_light")
elseif string.find(s, "0") then
core.reload_module("colors.everforest")
end
end
core.add_thread(function()
local output = ""
local prev_line = ""
while true do
local buf = defaults:read_stdout()
if not buf then break end
if #buf > 0 then
output = output .. buf
repeat
local line, remainder = string.match(output, "(.-)\n(.*)")
if line then
output = remainder
if line ~= prev_line then
prev_line = line
parse_output(line)
end
end
until not line
end
coroutine.yield(.250)
end
core.warn("defaults loop died")
end) |

Not really. But you could use the
dirmonitorfunctionality to check if a file has been modified, and act accordingly.If the script is purely time-based, you could replicate it as a Lite XL plugin.
If this is about the same toggle that directs https://wiki.libsdl.org/SDL3/SDL_GetSystemTheme, when we port to SDL3 we'll add a listener for that.
