We had to fix a couple of compile errors that weren't showing while it
wasn't wired up (since I never just tried to compile TagOverlay.zig on
its own). We also changed the lifecycle to re-create/destroy the surface
to show/hide it, similar to the way that river-tag-overlay actually did
it.
Finally, I added @branchHint(.cold) to a few places in the event loop
where, if we're in the branch, the wm is definitely exiting, so it's
fine if they're cold (should almost never happen).
Now, I actually save the river-layer-shell-v1 and keep track of the
non-exclusive area. The layout calculation uses the usable area instead
of the entire output's geometry.
I removed boundary clamping for the floating windows because it was a
bit janky when hitting the edges. I'll probably add it back at some
point. I also made windows default to 75% of the usable area instead of
keeping their tiled size so that maximized windows look decent when
floating for the first time. Finally, since I removed the clamping, I
added a center_float keybind to center a floating window. If you're
cycling through focused windows and one isn't on the screen, you can use
the center_float bind to get the window visible again.
Replaced all divTrunc with divFloor to be consistent. I think they
should all be positive, anyways, so they'd be the same, but I like just
having one.
I was looking for places where it might have made sense to use something
like an arena or a fba instead of the C allocator, but almost all of the
allocations are for Wayland interfaces that are fairly long lived (and,
since they're using libwayland, need the C allocator).
Instead, I just found two places that could use buffers on the stack
instead. In Config.zig, we *were* allocating the config path with
fmt.AllocPrint, but std.fs.max_path_bytes exists, so we can just make
a buf of that size and save a heap allocation. This is only at start up
and on config reload so it doesn't do too much, but I'd like to remove
allocations when possible.
The other change is for utils.parseModifiers(). It was using
std.ascii.allocLowerString(), but we clamp the length of the string to
3-5 characters, so we can just make a 5 character buffer and then use
ascii.lowerString() instead. Again, not super helpful since the function
is (currently) only called when creating Configs, but it's still nice to
get rid of a heap alloc.
By default, each tag mask will use the default count and ratio. If the
mask gets modified by any of the commands, it gets added to a hash map.
When changing tag masks, the current count and ratio are stored, and
they're used again later if you switch back to that mask.
This commit also adds primary_count and primary_ratio to the general
settings for the config, so users can set a default count/ratio to use.
This uses KDL properties, i.e. "host=<hostname>" and can be applied to
any config type. An example is includes in examples/config.kdl.
```kdl
wallpaper_image_path "~/Pictures/desktop.png" host="desktop"
wallpaper_image_path "~/Pictures/laptop.png" host="laptop"
```
It's a new node "input" that, if taking a name, includes the specific
input device the block should apply to. If no name is supplied,
the block applies to all inputs. Order matters and later config blocks
can override previous ones.
The config isn't actually used yet.
Right now, the support is still incomplete (no way to set config) but
we get the devices and set them up and handle current/support events
for the river_libinput_device_v1 devices.
Load wallpaper_image_path from config with tilde expansion (environment
variables are not supported)
On the way for this commit, I also had to:
- Fix wallpaper not rendering on startup by triggering init from
the .wl_output handler, since wl_output.done is lost during the
initial roundtrip
- Re-render wallpapers on config reload when the path changes
- Fix crash in deinitWallpaperLayerSurface when wl_surface is null
This makes the WM run fine even if wallpaper_image fails to load for any
other reason. Right now, it's still just a black background. At some
point, I plan to add the ability to also just set a color as a
background but that's a fairly low priority.
Add interactive move/resize operations using configurable pointer bindings
(Mod4+BTN_LEFT to move, Mod4+BTN_RIGHT to resize). Tiled windows
automatically float when dragged or resized.
Add keyboard commands for floating windows:
- move_up/down/left/right: move by pixel amount
- resize_width/height: resize by pixel amount
- swap_next/swap_prev: swap position in window stack
Fix float dimension initialization when windows first become floating,
and fix clamp crash when resizing windows larger than output bounds.
Update example config with documented keybinds and new pointer_binds block.
As of this commit, there's not-yet a way to resize or move floating
windows, but it's possible to create one and focus through all windows.
Floating windows are always above tiled windows and, if floating window
is focused, that window is always above any another floating windows.
Windows have a separate float_{x, y, width, height} to remember their
floating location if they go from float=>tiled=>float again.
Primary ratio is per-output.
If an output is disconnected/disabled, its windows get sent to the
previous output in the output list. If all outputs are disconnected,
windows are added to an orphan list in the WM. Once an output is
re-added, the orphans are all given to that output.
When a window is sent to a new output, it keeps the same tags as it
had before. I may add an option to take the new output's tags.
- Rename focus_next/focus_prev to focus_next_window/focus_prev_window
- Add focus_next_output/focus_prev_output
- Add send_to_next_output/send_to_prev_output commands to move windows
between outputs
Split Seat.PendingManage.PendingFocus into separate pending output
and pending window structs
Fix window outputs when closing outputs
Keybinds go in a "keybinds" block and follow the format
<command> <modifiers> <keysym> <options>
But there's also a special "tag_bind" command that just takes modifiers
and one of set_output_tags, set_window_tags, toggle_output_tags, and
toggle_window_tags. It will automatically be used to loop through the
1-9 keys on tags 1<<0 to 1<<9, however, you can still implement those
commands individually if you want.
logWarnInvalidNodeArg() can be used for when a node has an invalid type
for its argument.
logDebugSettingNode() prints the configuration name and the value being
set.
Config goes in $XDG_CONFIG_HOME/beansprout/config.kdl or
$HOME/.config/beansprout/config.kdl
Config is in the kdl format. Right now, the supported options are
```zig
/// Width of window borders in pixels
border_width: u8 = 2,
/// Color of focused window's border in 0xRRGGBBAA or 0xRRGGBB form
border_color_focused: RiverColor = utils.parseRgbaComptime("0x89b4fa"),
/// Color of uffocused windows' borders in 0xRRGGBBAA or 0xRRGGBB form
border_color_unfocused: RiverColor = utils.parseRgbaComptime("0x1e1e2e"),
/// Where a new window should attach, top or bottom of the stack
attach_mode: AttachMode = .top,
/// Should focus change when the cursor moves onto a new window
focus_follows_pointer: bool = true,
/// Should the pointer warp to the center of newly-focused windows
pointer_warp_on_focus_change: bool = true,
```
I plan to add Keybinds shortly. If parsing the configuration fails,
the default config will be used and the WM will continue loading.
Right now, colors are hardcoded in the Config in main.zig.
This commit also adds a couple of new keybinds for navigating between
windows. All keybinds are hardcoded as well right now.
