hyprland/language active keymap does not update

[xadips]

The module fails to initialize with my keyboard and I can't seem to get it to work. Current module config.

"hyprland/language": {
        "format": "test {}",
        "format-us": "us",
        "format-lt": "lt",
        "keyboard-name": "duckychannel-international-co.,-ltd.-ducky-keyboard"
}

I'm not sure whether this is an issue with waybar module or hyprland handling keyboards, there's currently multiple keyboards detected probably because of my keyboard firmware hyprctl devices

But only a single one gets its keymap changed when I use the keymap toggle keybind, I've tried setting the keyboard name to all of the above restarting waybar but still got the same error with all of them.

[d4r1us-drk]

Mine gets initialized, but when I change the layout with the keybinding, the indicator doesn't change.

config:

  "hyprland/language": {
    "format": "{} \udb80\udf0c",
    "format-en": "US",
    "format-es": "ES",
    "keyboard-name": "at-translated-set-2-keyboard",
    "on-click": "hyprctl switchxkblayout at-translated-set-2-keyboard next"
  },

The logs don't show anything useful as far as I can see, it shows when I change the layout, but that's it:

Using waybar-hyprland version 0.9.17

[xadips]

After getting the newest commit I can see the indicator but have the same issue of the keymap not changing when I change it with my keybind grp:alt_shift_toggle

[xadips]

using version 0.9.17.r161.g757f20fc-1 The keymap only updates on waybar restart and stays the same no matter @d4r1us-drk try using the latest commit, for some people it helped, same as https://github.com/Alexays/Waybar/issues/1989

[d4r1us-drk]

I installed waybar-hyprland-git-0.9.17.r161.g757f20fc-1 from the AUR and now the indicator changes with the keybind, which is weird. I forgot to say that the previous behavior was the same as @xadips's situation, the indicator only updates on restart and then stays the same. But now weirdly enough I installed the latest commit and it's working fine.

Also when I first installed waybar-hyprland (last Saturday I think), I installed the git version from the AUR and the module failed to initialize, but when I changed the layout with the keybind, it fixed itself. So I installed the version 0.9.17 and the problem was gone, then the thing stopped updating the keymap and the rest is what I did right now.

[d4r1us-drk]

After further testing, I realized this has something to do with the "keyboard-name" variable, when I deleted it, the issue was fixed on version 0.9.17 (not the latest git), I guess now the module now picks whatever keyboard is set to default, which is better for me actually, because I use external keyboards on my laptop. Maybe this issue was all about we setting one specific keyboard with this variable, in which case it's obvious that the indicator will not change if another keyboard is connected and set by default by Hyprland.

[xadips]

Version 0.9.17 core dumps for me, can't really check, but it could be to hyprland setting the wrong main keyboard as my keyboard is detected as multiple keyboards currently.

Sadly still doesn't work just wrote myself a custom script to grep the current layout for my keyboard name as a band-aid workaround for now, will revisit if there's any updates to this module.

#!/bin/bash
LAYOUT=$(hyprctl devices | rg -A 2 'duckychannel-international-co.,-ltd.-ducky-keyboard-1' | grep keymap | awk '{ print $3 }')
[[ "$LAYOUT" == "English" ]] && echo "us" || echo "lt"

"custom/keymap": {
        "format": "{}",
        "exec": "bash ~/.config/waybar/scripts/keymap.sh",
        "interval": 1
    }

Bumping up, as I have the same situation with multiple keyboards. Perhaps, it has something to do with the module not accepting an array of values for a variable: if you pass it in brackets like in module lists (["keyboard 1", "keybopard2"]), you get:

[warning] module hyprland/language: Disabling module "hyprland/language", Type is not convertible to string

[xadips]

@Alexays #2424 only fixed capslock,numlock toggle issues in keyboard state module, hyprland/language still has issues when it finds multiple keyboards as in language doesn't change when switching, please re-open.

I have the same problem.. After diving in the hyprland language module source code and looking at my debug logs, I might found out that the dispatcher delimiter is , and in our keyboard name, there is a comma.. that means, that the event is parsed incorrectly:

my debug log:

[2023-12-19 11:03:31.793] [debug] hyprland IPC received activelayout>>hp,-inc-hyperx-alloy-origins,English (US)
#                                                                       ^ not delimiter           ^ the delimiter

language.cpp:

void Language::onEvent(const std::string& ev) {
  std::lock_guard<std::mutex> lg(mutex_);
  std::string kbName(begin(ev) + ev.find_last_of('>') + 1, begin(ev) + ev.find_first_of(','));
  //                                                                                     ^ this tries to find the delimiter
  // in my case, kbName will be 'hp' instead of 'hp,-inc-hyperx-alloy-origins
  auto layoutName = ev.substr(ev.find_first_of(',') + 1);

  if (config_.isMember("keyboard-name") && kbName != config_["keyboard-name"].asString())
    return;  // ignore

  layoutName = waybar::util::sanitize_string(layoutName);

  layout_ = getLayout(layoutName);

  spdlog::debug("hyprland language onevent with {}", layoutName);

  dp.emit();
}

Please note that i haven't really try to fix the code or really debug the source code, since i haven't pulled the wayland source code and mess with it. But I think that we need to adjust the delimiter to be ; instead of , to prevent this problem. I also haven't figured out how to adjust the format of the IPC..

[s1syph0s]

@Alexays I would like to fix this issue by changing the find_first_of method.. is there any reason why find_first_of method is used and not find_last_of?

[holisticode]

Sorry but I am not sure I understand how multiple keyboards need to be handled. The ticket is closed but I still have the issue that I have two keyboards, and only one seems to be supported by the widget.

That is, when I try to add both (comma-separated?), the widget doesn't work, and it never changes the content. So currently I have just one keyboard (the external one) enabled, but if I disconnect the laptop to use standalone, of course it doesn't work anymore.

Thanks for clarifying how to have the widget work for both keyboards.
