From 37a2725da41e363fcdca12d0374b192cd03905d0 Mon Sep 17 00:00:00 2001 From: BossCode45 Date: Wed, 28 Jun 2023 21:24:59 +1200 Subject: feat: Added key chording Probably a hacky mess but oh well. Key chords can be done by seperating binds in string with ` `. You can set the quit bind with `quitkey`, default mod+g. (Chords also exited when pressing unbound keys). --- keybinds.cpp | 144 +++++++++++++++++++++++++++++++++++++++++++++++++---------- keybinds.h | 24 +++++++++- main.cpp | 2 +- readme.html | 87 +++++++++++++++++++----------------- readme.org | 5 ++- util.cpp | 7 +++ util.h | 3 +- 7 files changed, 203 insertions(+), 69 deletions(-) diff --git a/keybinds.cpp b/keybinds.cpp index 8448eed..b51bf6e 100644 --- a/keybinds.cpp +++ b/keybinds.cpp @@ -2,53 +2,98 @@ #include #include #include +#include #include +#include "commands.h" #include "error.h" #include "keybinds.h" #include "util.h" using std::string, std::cout, std::endl;

This only just works, multiple monitors aren't supported and floating windows cannot move and there is no resizing. Many features are just hacked together and are likely to break. However, it is just about usable so if you really want to try then go for it! (feel free to make an issue if you have any questions).

3.2. Config

You can configure YATwm with the config file in $HOME/.config/YATwm/config or $XDG_CONFIG_HOME/YATwm/config if you have that set. I have provided an example config file in the project dir that has all the variables set to their defaults (this will also be installed to /etc/YATwm/config.
It should alert you with a notification if you have an error, and put the error your log file. If the whole file is missing then it will use the default in /etc/YATwm/config.

3.2.1. Syntax

3.2.1. Syntax

The config file is a list of commands. Each command should be on a new line. For example, to set the gaps you would use the gaps command like this gaps 10 (make sure this is all there is on that line). This says to call the command gaps with the arguments of 10. Commands can have multiple arguments and these should be separated with a space, if you want a space in one of the arguments then wrap the arg in quotes, e.g. addWorkspace "1: A" 1, here the arguments are 1: A and 1. If you want to have a quote in your argument then make sure that arg is wrapped in quotes or escape it with \ (e.g. \'), to insert \ then use \\. If you want to have multiple commands on the same line, e.g. binding a key to multiple commands, then use ; as an argument on its own to separate them (tip: if you are using this for keybinds then enclose all the keybind commands in quotes, e.g. bind mod+l "spawn i3lock ; spawn systemctl suspend").
