Second argument of substr is the length of the substring, _not_ the position. With positions, it's better to do like this.
Example:
```sh
[2023-01-29 13:08:00.927] [debug] hyprland IPC received activelayout>>ITE Tech. Inc. ITE Device(8910) Keyboard,Russian (with Ukrainian-Belorussian layout)
[2023-01-29 13:08:00.927] [debug] kbName is ITE Tech. Inc. ITE Device(8910) Keyboard,Russian (with
```
After the fix it's correct:
```sh
[2023-01-29 13:11:11.408] [debug] hyprland IPC received activelayout>>ITE Tech. Inc. ITE Device(8910) Keyboard,Russian (with Ukrainian-Belorussian layout)
[2023-01-29 13:11:11.408] [debug] kbName is ITE Tech. Inc. ITE Device(8910) Keyboard
```
There were two main issues with fmtlib and C++20 mode:
- `fmt::format` defaults to compile-time argument checking and requires
using `fmt::runtime(format_string)` to bypass that.
- `std::format` implementation introduces conflicting declarations and
we have to specify the namespace for all `format`/`format_to` calls.
The current output form of `hyprctl devices` is like this:
```
Keyboard at 6f80ad70:
ITE Tech. Inc. ITE Device(8910) Keyboard
rules: r "", m "", l "us,ru", v "", o "grp:alt_shift_toggle"
active keymap: Russian
main: no
```
That is, `Keyboard at` goes _before_ the keyboard name, so looking for `Keyboard at` only makes it skip to the keyboard _after_ the one that the user specified.
The first crash occurs when trying to parse the
ID of a workspace as an uint, since named
workspaces has negative IDs. This is fixed by
using ints for workspace IDs instead of uints.
The second crash occurs when converting a
workspace name that isn't a number to an integer.
This is fixed by wrapping std::stoi in a try
block and only sorting by number, when both names
can successfully be converted to integers.
The hyprland/window widget had an assertion ensuring that the output
from hyprctl matched the currently selected workspace id. However this
assertion fails if workspaces are switched too quickly, causing the
selected workspace to differ in id from the one in hyprctl, failing this
assertion which then crashes the entire program.
This fix simply changes this assertion into an if statement, and if a
mismatch is found, empty string is returned as the window name.
