KeyboardLayout show all layouts instead of current

[Jofsey]

KeyboardLayout widget uses setxkbmap -query to get current layout, but in my case this command prints all layouts instead of current:

$ setxkbmap -query
rules:      evdev
model:      pc104
layout:     us,ru
options:    grp:caps_toggle,grp_led:scroll

This situation is also described here

Can use skb? http://plhk.ru/static/skb/skb-0.4.tar.gz
On python:

import subprocess

keyboard = subprocess.check_output(['skb', '-now']).strip()
print(unicode(keyboard))

As a variant, yes. This code is suitable. But I still hope to find solution which uses no external tools (only default X environment).

Looking at the code for setxkbmap, it looks pretty dumb (i.e. it just takes whatever string the X server gives it and prints that). Are these in any particular order?

[Jofsey]

The order doesn't depend on current layout. Guess it is the same as in /etc/X11/xorg.conf.d/N-keyboard-layout.conf

This solution requeres no external tools, but works only for one or two layouts. Not ideal, but cover ~98% cases. I'll write the fix if noone will propose a better solution.

Another method. Using kbdd(https://github.com/qnikst/kbdd).

import dbus

languages = {
    '0': 'EN',
    '1': 'RU',
}

def main():
    remote_bus = dbus.SessionBus()

    # Check if kbdd is running.
    system_service_list = remote_bus.get_object('org.freedesktop.DBus', '/org/freedesktop/DBus').ListNames()

    kbdd_api_found = 0
    for service in system_service_list:
        if service == 'ru.gentoo.KbddService':
            kbdd_api_found = 1
            break
    if not kbdd_api_found:
        return -1

    # Get kbdd dbus api
    kbdd_service = remote_bus.get_object('ru.gentoo.KbddService', '/ru/gentoo/KbddService')

    # Connect to kdbb.
    answer = kbdd_service.getCurrentLayout()
    return answer

if __name__ == "__main__":
    result = main()
    print(languages[unicode(result)])

import subprocess
import re

languages = {
    'first': 'EN',
    'second': 'RU',
}

regular_strings = {
    'hexadecimal': {
        'first': """\w{4}e\w{3}""",
        'second': """\w{4}f\w{3}""",
    },
    'binary': {
        'first': """\w{4}0\w{3}""",
        'second': """\w{4}1\w{3}""",
    },
    "inetger": "\d{8}",
    "led_mask": """LED mask:\s\s\w{8}""",
}

data = subprocess.check_output(['xset', '-q'])
raw_list = []

for item in data.strip().splitlines():
    if re.search(regular_strings['led_mask'], item):
        raw_led_mask = re.search(regular_strings['led_mask'], item).group()
        raw_list = raw_led_mask.split(':')
        led_mask = raw_list[1].strip()
        break

print("led_mask", led_mask)

if not re.search(regular_strings['inetger'], led_mask):
    cur_regular_strings = regular_strings['hexadecimal']
else:
    cur_regular_strings = regular_strings['binary']

if re.search(cur_regular_strings['first'], led_mask):
    print languages['first']
elif re.search(cur_regular_strings['second'], led_mask):
    print languages['second']
else:
    print(None)

I did some tests for this case.

• if layout is set from console like setxkbmap -layout us,lt,cn -option grp:alt_shift_toggle,compose:menu,grp_led:scroll the query output will have all 'us,lt,cn' layouts.
• with good qtile config, ex. widget.KeyboardLayout(configured_keyboards=['us', 'lt', 'ru phonetic']) query gives current layout as expected
• but if I run setxkbmap and reload Qtile - widget works a little bit strange

I suggest to close this issue
