+# Userspace: Sharing Code Between Keymaps
If you use more than one keyboard with a similar keymap, you might see the benefit in being able to share code between them. Create your own folder in `users/` named the same as your keymap (ideally your github username, `<name>`) with the following structure:
* `/users/<name>/` (added to the path automatically)
- * `readme.md`
+ * `readme.md` (optional, recommended)
* `rules.mk` (included automatically)
* `<name>.h` (optional)
* `<name>.c` (optional)
+ * `config.h` (optional)
`<name>.c` will need to be added to the SRC in `rules.mk` like this:
make planck:<name>
-For example,
+For example,
make planck:jack
Will include the `/users/jack/` folder in the path, along with `/users/jack/rules.mk`.
+Additionally, `config.h` here will be processed like the same file in your keymap folder. This is handled separately from the `<name>.h` file.
+
+The reason for this, is that `<name>.h` won't be added in time to add settings (such as `#define TAPPING_TERM 100`), and including the `<name.h>` file in any `config.h` files will result in compile issues.
+
+So you should use the `config.h` for QMK settings, and the `<name>.h` file for user or keymap specific settings.
+
+`/users/<name>/rules.mk` will be included in the build _after_ the `rules.mk` from your keymap. This allows you to have features in your userspace `rules.mk` that depend on individual QMK features that may or may not be available on a specific keyboard. For example, if you have RGB control features shared between all your keyboards that support RGB lighting, you can `define RGB_ENABLE` in your keymap `rules.mk` and then check for the variable in your userspace `rules.mk` like this:
+```make
+ifdef RGB_ENABLE
+ # Include my fancy rgb functions source here
+endif
+```
+Because of this, any time you turn on QMK features in your `users/<name>/rules.mk`, you should conditionally enable them only if the flag isn't already defined, like this:
+```make
+ifndef TAP_DANCE_ENABLE
+ TAP_DANCE_ENABLE = yes
+endif
+```
+This will ensure that you can explicitly turn off features for an individual keymap.

+## `Config.h`
+
+If you do add a `config,h` file, you want to make sure that it only gets processed once. So you may want to start off with something like this:
+
+```c
+#ifndef USERSPACE_CONFIG_H
+#define USERSPACE_CONFIG_H
+
+// Put normal config.h settings here:
+
+#endif // !USERSPACE_CONFIG_H
+```
+
+You can use any option hre that you could use in your keymap's `config.h` file. You can find a list of vales [here](config_options.md).

## Example
For a brief example, checkout `/users/_example/` , or for a more detailed examples check out [`template.h`](https://github.com/qmk/qmk_firmware/blob/master/users/drashna/template.h) and [`template.c`](https://github.com/qmk/qmk_firmware/blob/master/users/drashna/template.c) in `/users/drashna/` .
-### Consolidated Macros
+### Consolidated Macros
-If you wanted to consoludate macros and other functions into your userspace for all of your keymaps, you can do that. The issue is that you then cannot call any function defined in your userspace, or it gets complicated. To better handle this, you can call the functions here and create new functions to use in individual keymaps.

-First, you'd want to go through all of your `keymap.c` files and replace `process_record_user` with `process_record_keymap` instead. This way, you can still use keyboard specific codes on those boards, and use your custom "global" keycodes as well. You'll also want to replace `SAFE_RANGE` with `NEW_SAFE_RANGE` so that you wont have any overlappind keycodes

You'll also want to replace `SAFE_RANGE` with `NEW_SAFE_RANGE` so that you wont have any overlapping keycodes
Then add `#include <name.h>` to all of your keymap.c files. This allows you to use these new keycodes without having to redefine them in each keymap.
#include "quantum.h"
-// Define all of
+// Define all of
enum custom_keycodes {
KC_MAKE = SAFE_RANGE,
NEW_SAFE_RANGE //use "NEW_SAFE_RANGE" for keymap specific codes
SEND_STRING("make " QMK_KEYBOARD ":" QMK_KEYMAP
#if (defined(BOOTLOADER_DFU) || defined(BOOTLOADER_LUFA_DFU) || defined(BOOTLOADER_QMK_DFU))
":dfu "
-#elif defined(BOOTLOADER_HALFKEY)
+#elif defined(BOOTLOADER_HALFKAY)
":teensy "
#elif defined(BOOTLOADER_CATERINA)
":avrdude "
}
```
-This will add a new `KC_MAKE` keycode that can be used in any of your keymaps. And this keycode will output `make <keyboard>:<keymap">`, making frequent compiling easier. And this will work with any keyboard and any keymap as it will output the current boards info, so that you don't have to type this out every time.

-Additionally, this should flash the newly compiled firmware automatically, using the correct utility, based on the bootloader settings (or default to just generating the HEX file). However, it should be noted that this may not work on all systems (AVRDUDE doesn't work on WSL, namely).

+## Override default userspace
+
+By default the userspace used will be the same as the keymap name. In some situations this isn't desirable. For instance, if you use the [layout](feature_layouts.md) feature you can't use the same name for different keymaps (e.g. ANSI and ISO). You can name your layouts `mylayout-ansi` and `mylayout-iso` and add the following line to your layout's `rules.mk`:
+
+```
+USER_NAME := mylayout
+```
