It is aimed at developers who want to work on QMK itself. + +## History + +Historically QMK has been configured through a combination of two mechanisms- `rules.mk` and `config.h`. While this worked well when QMK was only a handful of keyboards we've grown to encompass nearly 1500 supported keyboards. That extrapolates out to 6000 configuration files under `keyboards/` alone! The freeform nature of these files and the unique patterns people have used to avoid duplication have made ongoing maintenance a challenge, and a large number of our keyboards follow patterns that are outdated and sometimes harder to understand. + +We have also been working on bringing the power of QMK to people who aren't comformable with a CLI, and other projects such as VIA are working to make using QMK as easy as installing a program. These tools need information about how a keyboard is laid out or what pins and features are available so that users can take full advantage of QMK. We introduced `info.json` as a first step towards this. The QMK API is an effort to combine these 3 sources of information- `config.h`, `rules.mk`, and `info.json`- into a single source of truth that end-user tools can use. + +Now we have support for generating `rules.mk` and `config.h` values from `info.json`, allowing us to have a single source of truth. This will allow us to use automated tooling to maintain keyboards saving a lot of time and maintenance work. + +## Overview + +On the C side of things nothing changes. When you need to create a new rule or define you follow the same process: + +1. Add it to `docs/config_options.md` +1. Set a default in the appropriate core file +1. Add your ifdef statements as needed + +You will then need to add support for your new configuration to `info.json`. The basic process is: + +1. Add it to the schema in `data/schemas/keyboards.jsonschema` +1. Add a mapping in `data/maps` +1. (optional and discoraged) Add code to extract/generate it to: + * `lib/python/qmk/info.py` + * `lib/python/qmk/cli/generate/config_h.py` + * `lib/python/qmk/cli/generate/rules_mk.py` + +## Adding an option to info.json + +This section describes adding support for a `config.h`/`rules.mk` value to info.json. + +### Add it to the schema + +QMK maintains [jsonschema](https://json-schema.org/) files in `data/schemas`. The values that go into keyboard-specific `info.json` files are kept in `keyboard.jsonschema`. Any value you want to make available to end users to edit must go in here. + +In some cases you can simply add a new top-level key. Some examples to follow are `keyboard_name`, `maintainer`, `processor`, and `url`. This is appropriate when your option is self-contained and not directly related to other options. + +In other cases you should group like options together in an `object`. This is particularly true when adding support for a feature. Some examples to follow for this are `indicators`, `matrix_pins`, and `rgblight`. If you are not sure how to integrate your new option(s) [open an issue](https://github.com/qmk/qmk_firmware/issues/new?assignees=&labels=cli%2C+python&template=other_issues.md&title=) or [join #cli on Discord](https://discord.gg/heQPAgy) and start a conversation there. + +### Add a mapping + +In most cases you can add a simple mapping. These are maintained as JSON files in `data/mappings/info_config.json` and `data/mappings/info_rules.json`, and control mapping for `config.h` and `rules.mk`, respectively. Each mapping is keyed by the `config.h` or `rules.mk` variable, and the value is a hash with the following keys: + +* `info_key`: (required) The location within `info.json` for this value. See below. +* `value_type`: (optional) Default `str`. The format for this variable's value. See below. +* `to_json`: (optional) Default `true`. Set to `false` to exclude this mapping from info.json +* `to_c`: (optional) Default `true`. Set to `false` to exclude this mapping from config.h +* `warn_duplicate`: (optional) Default `true`. Set to `false` to turn off warning when a value exists in both places + +#### Info Key + +We use JSON dot notation to address variables within info.json. For example, to access `info_json["rgblight"]["split_count"]` I would specify `rgblight.split_count`. This allows you to address deeply nested keys with a simple string. + +Under the hood we use [Dotty Dict](https://dotty-dict.readthedocs.io/en/latest/), you can refer to that documentation for how these strings are converted to object access. + +#### Value Types + +By default we treat all values as simple strings. If your value is more complex you can use one of these types to intelligently parse the data: + +* `array`: A comma separated array of strings +* `array.int`: A comma separated array of integers +* `int`: An integer +* `hex`: A number formatted as hex +* `list`: A space separate array of strings +* `mapping`: A hash of key/value pairs + +### Add code to extract it + +Most use cases can be solved by the mapping files described above. If yours can't you can instead write code to extract your config values. + +Whenever QMK generates a complete `info.json` it extracts information from `config.h` and `rules.mk`. You will need to add code for your new config value to `lib/python/qmk/info.py`. Typically this means adding a new `_extract_<feature>()` function and then calling your function in either `_extract_config_h()` or `_extract_rules_mk()`. + +If you are not sure how to edit this file or are not comfortable with Python [open an issue](https://github.com/qmk/qmk_firmware/issues/new?assignees=&labels=cli%2C+python&template=other_issues.md&title=) or [join #cli on Discord](https://discord.gg/heQPAgy) and someone can help you with this part. + +### Add code to generate it + +The final piece of the puzzle is providing your new option to the build system. This is done by generating two files: + +* `.build/obj_<keyboard>/src/info_config.h` +* `.build/obj_<keyboard>/src/rules.mk` + +These two files are generated by the code here: + +* `lib/python/qmk/cli/generate/config_h.py` +* `lib/python/qmk/cli/generate/rules_mk.py` + +For `config.h` values you'll need to write a function for your rule(s) and call that function in `generate_config_h()`. + +If you have a new top-level `info.json` key for `rules.mk` you can simply add your keys to `info_to_rules` at the top of `lib/python/qmk/cli/generate/rules_mk.py`. Otherwise you'll need to create a new if block for your feature in `generate_rules_mk()`. diff --git a/docs/feature_audio.md b/docs/feature_audio.md index 5132dfe971..68ba4477a5 100644 --- a/docs/feature_audio.md +++ b/docs/feature_audio.md @@ -215,12 +215,6 @@ This is still a WIP, but check out `quantum/process_keycode/process_midi.c` to s AU_OFF, AU_TOG, - #ifdef FAUXCLICKY_ENABLE - FC_ON, - FC_OFF, - FC_TOG, - #endif - // Music mode on/off/toggle MU_ON, MU_OFF, diff --git a/docs/feature_backlight.md b/docs/feature_backlight.md index a558af64e1..2adb16e4a8 100644 --- a/docs/feature_backlight.md +++ b/docs/feature_backlight.md @@ -93,18 +93,18 @@ BACKLIGHT_DRIVER = pwm On AVR boards, QMK automatically decides which driver to use according to the following table: -|Backlight Pin|AT90USB64/128|ATmega16/32U4|ATmega16/32U2|ATmega32A|ATmega328/P| -|-------------|-------------|-------------|-------------|---------|-----------| -|`B1` | | | | |Timer 1 | -|`B2` | | | | |Timer 1 | -|`B5` |Timer 1 |Timer 1 | | | | -|`B6` |Timer 1 |Timer 1 | | | | -|`B7` |Timer 1 |Timer 1 |Timer 1 | | | -|`C4` |Timer 3 | | | | | -|`C5` |Timer 3 | |Timer 1 | | | -|`C6` |Timer 3 |Timer 3 |Timer 1 | | | -|`D4` | | | |Timer 1 | | -|`D5` | | | |Timer 1 | | +|Backlight Pin|AT90USB64/128|AT90USB162|ATmega16/32U4|ATmega16/32U2|ATmega32A|ATmega328/P| +|-------------|-------------|----------|-------------|-------------|---------|-----------| +|`B1` | | | | | |Timer 1 | +|`B2` | | | | | |Timer 1 | +|`B5` |Timer 1 | |Timer 1 | | | | +|`B6` |Timer 1 | |Timer 1 | | | | +|`B7` |Timer 1 |Timer 1 |Timer 1 |Timer 1 | | | +|`C4` |Timer 3 | | | | | | +|`C5` |Timer 3 |Timer 1 | |Timer 1 | | | +|`C6` |Timer 3 |Timer 1 |Timer 3 |Timer 1 | | | +|`D4` | | | | |Timer 1 | | +|`D5` | | | | |Timer 1 | | All other pins will use timer-assisted software PWM: diff --git a/docs/feature_macros.md b/docs/feature_macros.md index 36fa761d21..aa1ebc337a 100644 --- a/docs/feature_macros.md +++ b/docs/feature_macros.md @@ -4,7 +4,7 @@ Macros allow you to send multiple keystrokes when pressing just one key.
