# btrtile — A Focus-Driven Tiling Layout
|
||
|
||
It provides a focus-driven, mouse- and keyboard-friendly tiling layout that grants you granular control over how clients are placed and resized.
|
||
|
||
|
||

|
||
# Why btrtile
|
||
|
||
While dwl’s patches folder is full of different layouts, I couldn't find suitable layout that would work well with my workflow and single ultrawide monitor setup. btrtile aims to solve that by introducing a layout strategy that splits clients according to user focus and pointer position.
|
||
|

|
||
|
||
# Features
|
||
|
||
- **Combined Tiling and Management**
|
||
Combines tiling layout and management of clients under one patchset.
|
||
|
||
- **Focus-Driven Splits**
|
||
When you add a new client, btrtile checks where your pointer is relative to the focused client’s geometry.
|
||
- If the pointer is on the left half (for a horizontally large client), the new client spawns on the left side, and vice versa.
|
||
- By default, new splits are 50/50.
|
||
|
||
- **Adaptive Splitting**
|
||
- If the area to be split is wider than its height, btrtile does a vertical split.
|
||
- Otherwise, it does a horizontal split.
|
||
|
||
- **Keyboard and Mouse Driven**
|
||
- Supports keyboard-based commands for quick ratio adjustments and client swapping.
|
||
- Mouse-based resizing and moving are integrated for more intuitive manipulation.
|
||

# How It Works
|
||
|
||
btrtile organizes clients using a binary tree data structure that represents splits either vertically or horizontally.
|
||
|
||
When a new client appears:
|
||
1. **Focused Client Detection**
|
||
btrtile checks your pointer location to find which client (if any) you’re interacting with.
|
||
2. **Split Creation**
|
||
- If there’s a focused client, btrtile creates a split node around it, placing the new client on the side where your pointer is.
|
||
|
||
3. **Ratio Management**
|
||
Each split node has a `split_ratio` (defaulting to 0.5). This ratio defines how much space is allocated to each child node. You can adjust this ratio using keyboard or mouse actions.

# What It Doesn’t Handle
|
||
|
||
- **Suckless philosophy**
|
||
- Yea, it's a bloat. I tried to hide the suck inside a single file as much I could. While this approach is not ideal, it's how it's at least for now.

||
# Configuring btrtile
|
||
|
||
btrtile adds couple variables to config.h to fine tune the mouse resizing of tiled clients.
|
||
|
||
1. **resize_factor**
|
||
- A multiplier to transfer pointer movement to client weight ratio. Depends heavily on mouse sensivity.
|
||
Defaults to 0.0002f.
|
||
|
||
2. **resize_interval_ms**
|
||
- A time based resize call limiter. Depends on framerate and screen refresh rate.
|
||
Defaults to 16ms. (~60 resize updates per second)
|
||
|
||
Fine tune these values to find the best values for your setup, smoother resizing can significally increase cpu overhead.
|
||
If mouse resizing feels sluggish, you can try compiling dwl with more aggressive optimization flags like -O2/-O3.

# Patch recommendations
|
||
|
||
1. **Patches that I use with my btrtile**
|
||
|
||
- [focusdir](https://codeberg.org/dwl/dwl-patches/src/branch/main/patches/focusdir)
|
||
Great patch to move focus between clients.
|
||
|
||
- [rotatetags](https://codeberg.org/dwl/dwl-patches/src/branch/main/patches/rotatetags)
|
||
Good patch to rotate the view or shift clients between tags.
|
||
|
||
- [warpcursor](https://codeberg.org/dwl/dwl-patches/src/branch/main/patches/warpcursor)
|
||
Moves cursor location to focused client.
|
||
|
||
- [pertag](https://codeberg.org/dwl/dwl-patches/src/branch/main/patches/pertag)
|
||
Allows each tag to have individual layout setups.
|
||
|
||
- [gaps](https://codeberg.org/dwl/dwl-patches/src/branch/main/patches/gaps)
|
||
Add gaps between clients.
