# hs.tiling
Add tiling window management powers to your [hammerspoon][hammerspoon]. (Fork of nathankot's [mjolnir.tiling](https://github.com/nathankot/mjolnir.tiling).)
## Features
* Different layouts per space ([with this magic][magic])
* Multi-monitor supported
* Custom layouts
## Quick start
First up, install [Hammerspoon][hammerspoon] if you haven't already.
Then install `hs.tiling` by cloning into your hammerspoon configuration directory:
```
mkdir -p $HOME/.hammerspoon/hs
git clone https://github.com/dsanson/hs.tiling $HOME/.hammerspoon/hs/tiling
```
In your `~/.hammerspoon/init.lua`:
```lua
local tiling = require "hs.tiling"
local hotkey = require "hs.hotkey"
local mash = {"ctrl", "cmd"}
hotkey.bind(mash, "c", function() tiling.cycleLayout() end)
hotkey.bind(mash, "j", function() tiling.cycle(1) end)
hotkey.bind(mash, "k", function() tiling.cycle(-1) end)
hotkey.bind(mash, "space", function() tiling.promote() end)
hotkey.bind(mash, "f", function() tiling.goToLayout("fullscreen") end)
-- If you want to set the layouts that are enabled
tiling.set('layouts', {
'fullscreen', 'main-vertical'
})
```
## Updating
To update to the latest `hs.tiling`, pull the latest from git:
```
cd $HOME/.hammerspoon/hs/tiling
git pull
```
## Using custom layouts
You can define your own layouts like so (please see [layouts.lua](/layouts.lua) for definition examples:)
```lua
tiling.addLayout('custom', function(windows)
fnutils.each(windows, function(window)
window:maximize()
end)
end)
```
## Floating Windows
Using `tiling.toggleFloat` you can toggle whether or not a window that is on your desktop will be
included in your tiling calculations. You can optionally pass in a function as a callback to process
the window if it was tiled.
```lua
-- Push the window into the exact center of the screen
local function center(window)
frame = window:screen():frame()
frame.x = (frame.w / 2) - (frame.w / 4)
frame.y = (frame.h / 2) - (frame.h / 4)
frame.w = frame.w / 2
frame.h = frame.h / 2
window:setFrame(frame)
end
hotkey.bind(mash, "f", function() tiling.toggleFloat(center) end)
```
## Layouts
These are the layouts that come with `hs.tiling`:
Name | Screenshot
------------------------------------------- | ------------------------------------
`fullscreen` | ![fullscreen](https://raw.github.com/dsanson/hs.tiling/master/screenshots/fullscreen.png)
`main-vertical` | ![main-vertical](https://raw.github.com/dsanson/hs.tiling/master/screenshots/main-vertical.png)
`main-horizontal` | ![main-horizontal](https://raw.github.com/dsanson/hs.tiling/master/screenshots/main-horizontal.png)
`rows` | ![rows](https://raw.github.com/dsanson/hs.tiling/master/screenshots/rows.png)
`columns` | ![columns](https://raw.github.com/dsanson/hs.tiling/master/screenshots/columns.png)
`gp-vertical` | ![gp-vertical](https://raw.github.com/dsanson/hs.tiling/master/screenshots/gp-vertical.png)
`gp-horizontal` | ![gp-horizontal](https://raw.github.com/dsanson/hs.tiling/master/screenshots/gp-horizontal.png)
## Variable Layouts
I am experimenting with adding support for variable width layouts.
For now, I have added a variable width variant of `main-vertical`, called
`main-vertical-variable`. It it just like `main-vertical`, except the
proportion of the screen filled by the main window is determined by the value
of the global variable, `mainVertical`, which defaults to `0.5`. I've also
added two functions, `tiling.setMainVertical(val)`, which takes a value
between `0` and `1` (`0.25` means that the main window takes a quarter of the
screen, while the other windows take the remaining three quarters; `0.75`
means that the main window takes 3/4 of the screen, while the remaining
windows take 1/4, and so on) and `tiling.adjustMainVertical(factor)`, which
takes a negative or positive factor by which to adjust the value of
`mainVertical` (e.g., if `mainVertical` is `0.5`, then
`tiling.adjustMainVertical(-0.1)` sets it to `0.4`).
Here is how I use them in my `init.lua` (as
part of a "windows" mode using `hotkeys.modal`:
```
w:bind({},"left", function() tiling.adjustMainVertical(-0.05) end)
w:bind({},"right", function() tiling.adjustMainVertical(0.05) end)
w:bind({},"=", function() tiling.setMainVertical(0.5) end)
```
Once I have all the kinks worked out, I plan to enable this feature for
`main-vertical` and `gp-vertical`, as well as a corresponding feature for
`main-horizontal` and `gp-horizontal`.

## Contributors
This is a port of [nathankot's](https://github.com/nathankot) [mjolnir.tiling][mjolnir.tiling].
I replaced
references to mjolnir extensions (e.g., `mjolnir.window`) with references to
the corresponding hammerspoon extensions (e.g., `hs.window`). I rewrote
function calls in camelCase where necessary. I renamed `tiling.lua` to
`init.lua`. It seems to work.

Thanks to Nathan and all these contributors for making mjolnir.tiling, and making it so easy to port over to hammerspoon!
## To-do
* [x] Better documentation
* [x] More layouts
* [x] Allow globally enabling/disabling layouts
* [ ] Functions to move windows across spaces
* [ ] Event-based tiling, although requires [sdegutis/mjolnir#72][72]
