# Layouts: Using a Keymap with Multiple Keyboards
|
|
|
|
The `layouts/` folder contains different physical key layouts that can apply to different keyboards.
|
|
|
|
```
|
|
layouts/
|
|
+ default/
|
|
| + 60_ansi/
|
|
| | + readme.md
|
|
| | + layout.json
|
|
| | + a_good_keymap/
|
|
| | | + keymap.c
|
|
| | | + readme.md
|
|
| | | + config.h
|
|
| | | + rules.mk
|
|
| | + <keymap folder>/
|
|
| | + ...
|
|
| + <layout folder>/
|
|
+ community/
|
|
| + <layout folder>/
|
|
| + ...
|
|
```
|
|
|
|
The `layouts/default/` and `layouts/community/` are two examples of layout "repositories" - currently `default` will contain all of the information concerning the layout, and one default keymap named `default_<layout>`, for users to use as a reference. `community` contains all of the community keymaps, with the eventual goal of being split-off into a separate repo for users to clone into `layouts/`. QMK searches through all folders in `layouts/`, so it's possible to have multiple repositories here.
|
|
|
|
Each layout folder is named (`[a-z0-9_]`) after the physical aspects of the layout, in the most generic way possible, and contains a `readme.md` with the layout to be defined by the keyboard:
|
|
|
|
```markdown
|
|
# 60_ansi
|
|
|
|
LAYOUT_60_ansi
|
|
```
|
|
|
|
New names should try to stick to the standards set by existing layouts, and can be discussed in the PR/Issue.
|
|
|
|
## Supporting a Layout
|
|
|
|
For a keyboard to support a layout, the variable must be defined in it's `<keyboard>.h`, and match the number of arguments/keys (and preferably the physical layout):
|
|
|
|
```c
|
|
#define LAYOUT_60_ansi KEYMAP_ANSI
|
|
```
|
|
|
|
The name of the layout must match this regex: `[a-z0-9_]+`
|
|
|
|
The folder name must be added to the keyboard's `rules.mk`:
|
|
|
|
```
|
|
LAYOUTS = 60_ansi
|
|
```
|
|
|
|
`LAYOUTS` can be set in any keyboard folder level's `rules.mk`:
|
|
|
|
```
|
|
LAYOUTS = 60_iso
|
|
```
|
|
|
|
but the `LAYOUT_<layout>` variable must be defined in `<folder>.h` as well.
|
|
|
|
## Building a Keymap
|
|
|
|
You should be able to build the keyboard keymap with a command in this format:
|
|
|
|
```
|
|
make <keyboard>:<layout>
|
|
```
|
|
|
|
### Conflicting layouts
|
|
When a keyboard supports multiple layout options,
|
|
|
|
```
|
|
LAYOUTS = ortho_4x4 ortho_4x12
|
|
```
|
|
|
|
And a layout exists for both options,
|
|
```
|
|
layouts/
|
|
+ community/
|
|
| + ortho_4x4/
|
|
| | + <layout>/
|
|
| | | + ...
|
|
| + ortho_4x12/
|
|
| | + <layout>/
|
|
| | | + ...
|
|
| + ...
|
|
```
|
|
|
|
The FORCE_LAYOUT argument can be used to specify which layout to build
|
|
|
|
```
|
|
make <keyboard>:<layout> FORCE_LAYOUT=ortho_4x4
|
|
make <keyboard>:<layout> FORCE_LAYOUT=ortho_4x12
|
|
```
|
|
|
|
## Tips for Making Layouts Keyboard-Agnostic
|
|
|
|
### Includes
|
|
|
|
Instead of using `#include "planck.h"`, you can use this line to include whatever `<keyboard>.h` (`<folder>.h` should not be included here) file that is being compiled:
|
|
|
|
```c
|
|
#include QMK_KEYBOARD_H
|
|
```
|
|
|
|
If you want to keep some keyboard-specific code, you can use these variables to escape it with an `#ifdef` statement:
|
|
|
|
* `KEYBOARD_<folder1>_<folder2>`
|
|
|
|
For example:
|
|
|
|
```c
|
|
#ifdef KEYBOARD_planck
|
|
#ifdef KEYBOARD_planck_rev4
|
|
planck_rev4_function();
|
|
#endif
|
|
#endif
|
|
```
|
|
|
|
Note that the names are lowercase and match the folder/file names for the keyboard/revision exactly.
|
|
|
|
### Keymaps
|
|
|
|
In order to support both split and non-split keyboards with the same layout, you need to use the keyboard agnostic `LAYOUT_<layout name>` macro in your keymap. For instance, in order for a Let's Split and Planck to share the same layout file, you need to use `LAYOUT_ortho_4x12` instead of `LAYOUT_planck_grid` or just `{}` for a C array.
