# Canoe 🛶 - River Window Manager

A stacking window manager for the River Wayland compositor, written in Rust.
## Features
- Stacking window management
- Server-side decorations with classic window borders & titlebars
- Titlebar/edge window movement and resizing (Super+Drag anywhere)
- Multihead support (focus/send windows across outputs)
- Window switcher (keyboard cycle + desktop right-click menu)
- Window focus follows click
- Optional forcing server-side decorations via per-window rules
- Optional "swallowing" of client-side decoration via per-window rules
## Installation

cargo install canoe
```
## Running

river -c canoe
```

## Configuration
Canoe reads `~/.config/canoe/canoe.toml`.
The main modifier defaults to `super`, but you can change it:
```toml
main_modifier = "alt"
```
The launcher defaults to `fuzzel`. You can override it with a command or argv:
```toml
launcher_cmd = "fuzzel"
# Or with arguments:
launcher_cmd = ["fuzzel", "--dmenu"]
```
### UI Settings
UI options live under the `[ui]` table and let you tune borders, titlebars, and menu colors.
Colors accept `#RGB`, `#RRGGBB`, or `#RRGGBBAA`.
```toml
[ui]
border_width = 10
border_active = { outer = "#FFD000", mid = "#000000", inner = "#FFD000" }
border_inactive = { outer = "#000000", mid = "#000000", inner = "#000000" }
titlebar_text_active = "#000000"
titlebar_text_inactive = "#808080"
titlebar_bg_active = "#FFD000"
titlebar_bg_inactive = "#202020"
menu_bg = "#000000"
menu_text = "#FFFFFF"
menu_highlight_bg = "#FFD000"
menu_highlight_text = "#000000"
button_bg = "#202020"
button_highlight = "#FFD000"
button_shadow = "#000000"
font_name = "Sans"
font_size = 12.0
desktop_background = "#101010"
```
### Rule Matching
Rules live under `[[rules]]` in `canoe.toml`. App ID matching uses OR across the
app-id fields, and property matching uses AND across the listed properties.
```toml
[[rules]]
match_app_id = ["foot", "kitty"] # exact match, any value matches
match_app_id_prefix = "mate-" # prefix match (e.g. mate-calc)
match_props = ["toplevel", "csd_only"] # all props must match
```
Supported `match_props` values:
- `toplevel` (window has no parent)
- `csd_only` (client does not support SSD)
The matching windows can have parts of their content "swallowed". This removes
the client-side decoration on my Firefox, for instance:
```toml
match_app_id = "firefox-esr"
match_props = "toplevel"
force_ssd = true
swallow_top = 48
```
