I haven't looked at the commits but in general I'm a fan of the idea of switching to C++. It doesn't look like upstream is willing to switch, so this would have to be done in a permanent fork. |

I don't really see any reason against. Maybe I was too rude after all. If it's memory usage on some embedded system, dynamic allocations in C++ only work in favor on C++. I have already significantly reduced static memory usage. Because with dynamic alloc you only pay more memory as your config grows bigger. |
Also optimize `chord` struct size a bit. Looping over small array should be easily unrolled/vectorized.
Also allow includes to have non-.conf extensions.
Also split table to reduce memory size.
Use RTTI on listener socket.
Improve indicator on Wayland (resist forced changes). Optimize layer_indicator performance. Fix previous unnecessary LED setting. Compatible with previous settings because CAPS_LOCK equals 1. Based on pull-request initially proposed by @plague-spreader
Macro no longer allowes "words" (char sequences without delimiters). In order to write "Hello" it must be written as macro(H e l l o). Alternatively, it can be t(Hello) or type(Hello). Shell commands can't execute via `keyd do`. Example: macro(cmd(echo 1))
Also allow implicit layer creation on bindings.
Add leftctrl/leftsuper-alike key aliases. Allow ctrl as layer name equal to control. Allow multiname aliases in alias section.

Refactor config_backup class. Also use C++20 'using enum class'.
`keyd do` or `keyd bind` will copy user's credentials. Loaded .conf file will use keyd process credentials. Don't kill child processes in systemd config. Allow a train of IPC messages for optimization.
Remove full `*` wildcard support. Initially `m:*` was proposed by @jyn514 Additional wildcard `a:` to include abs pointer devices. When using `m:` those devices are excluded.

These commands may be useful to execute at user session startup. User bindings are loaded by explicit calling `keyd reload` from user. User bindings are located at `~/.config/keyd/bindings.conf`.

Implement file_reader class (simple fd->container). Some options allow significantly reduce executable size. Static part of libstdc++ now is only 130~150 Kb.

Not for merge.
Fixes issues with capslock indicator being reset (in Wayland, for example) (feel free to cherry-pick).
Fixes cursed issues with C fixed arrays by using C++ (partially).
The fact these issues exist is infuriating. Fixing this in pure C will only waste a lot of time.
