App icons in spaces?

[shajra]

First off, thanks for putting all this work into this project. Some of it is just a slick look-and-feel. But there are nice little things like getting app icon summaries in spaces that are very useful when leaning heavily on spaces. That's implemented in the shell example. I noticed it's not in the Lua example.

With the INFO environment variable, I think this is technically possible now. But I need help converting this JSON string to a Lua data structure. I could find something third-party or write my own. But it's probably easier to just popen a call to jq.

What is more likely to happen in the future is that you would give me this information directly as a Lua data structure. Or did I miss something in the code, and is this already possible?

I got it working... everything I needed was there in env. No need to mess with jq. This is wonderful. Thanks!

This is the script I am using for app icons:

local app_icons = require("app_icons")

local space_windows = sbar.add("item", {
  padding_left=10,
  padding_right=8,
  icon = {
    string = "􀆊",
    font = {
      style = "Heavy",
      size = 16.0,
    },
  },
  label = { drawing = false },
  display = "active",
})

space_windows:subscribe("space_windows_change", function(env)
  local icon_line = ""
  local no_app = true
  for app, count in pairs(env.INFO.apps) do
    no_app = false
    local lookup = app_icons[app]
    local icon = ((lookup == nil) and app_icons["default"] or lookup)
    icon_line = icon_line .. " " .. icon
  end
  if (no_app) then
    icon_line = " —"
  end
  sbar.animate("tanh", 10, function()
    spaces[env.INFO.space]:set({ label = icon_line })
  end)
end)

Thanks. My Lua isn't the strongest. What I remember from Ion3WM days supplemented with ChatGPT. Here's the function I got that does something pretty similar:

local function space_windows_change(env)
  local app_emojis = {}
  for name, _ in pairs(env.INFO.apps) do
    table.insert(app_emojis, emojis[name] or ":default:")
  end
  icon_strip = "—"
  if next(app_emojis) ~= nil
  then
    icon_strip = table.concat(app_emojis, " ")
  end
  sbar.set(spaces[env.INFO.space], {
    label = icon_strip
  })
end

I think I'll put in the animation.

Hi. Just continuing to chat here because it's convenient and relevant to the thread. You posted your code here, but is it in a repo anywhere? That would be easier to follow. I found your dotfiles repo, but it still seems to be on the shell-style configuration (including the experimental branch).

For now, I'm getting all my latest best ideas for Lua configuration from the example in SbarLua. I actually kind of prefer that. Do you have a plan to push some more features to the example repo here?

I don't yet have much to add beyond what's already there and the small amount I've figured out in this thread.

[FelixKratz]

My personal lua setup is not finalized yet, I work on it on and off but once it is ready I will create a branch in my dotfiles.

[FelixKratz]

I have added a first dotfile version to this branch: https://github.com/FelixKratz/dotfiles/tree/lua
