* docs: clarify in "Keymap Overview" what LAYOUT is and isn't
It is not strictly necessary to use LAYOUT macros in keyboard.c, but it
is a convenient abstraction of hardware internals, allowing focus on the
physical keyboard layout.
From the C source point of view LAYOUT is macro with a parameter list,
which expands to a array of rows that each is an array with a keyboard
scancode for each column. A macro parameter list is not an array, and
even less a single array.
Perhaps no big deal, but also no reason to give incorrect hints.
* docs: update "Understanding QMK's Code" to current code structure introduced in 96e2b13d1de
This part of the documentation was no longer correct. I tried updating
it, mainly copy editing and using github links to latest release.
This is not trying to fix all problems, but just trying to fix some
problems while reusing much of the old phrases and structure.
* Update docs to use "qmk format-python"
* New feature: `DYNAMIC_TAPPING_TERM_ENABLE`
3 new quantum keys to configure the tapping term on the fly.
* Replace sprintf call in tapping_term_report by get_u16_str
* Replace tab with 4 spaces
* Improve process_record system
Code based on @colinta's
* Rename and better handle functions
* Fix incorrect function call to process_record_user
* Add documentation for post_process_record
* Add both get_event_keycode and get_record_keycode functions
And add some comments about these functions
* Update code format
* Cleanup merge artifacts
While this was historically a valid possibility, nowadays, it reads
kinda weird, and the [Oxford Dictionaries Online suggests to avoid it](https://english.stackexchange.com/a/56010).
Thus, I removed it everywhere I found it.
Many instances in the QMK Docs referenced KEYMAP macros, which is outdated terminology.
Replaced most instances of KEYMAP with LAYOUT, to reflect the desired usage.
* Remove unused UNICODE(n) macro, update docs
* Add note about max length of unicode_map to docs
* QK_UNICODE_MAP → QK_UNICODEMAP
* Refactor process_unicode_map
* process_unicode_map → process_unicodemap
This is done for consistency: UNICODEMAP is the method (hence UNICODEMAP_ENABLE, process_unicodemap), whereas unicode_map is the mapping table itself.
* Update references and ordering in docs/understanding_qmk
* Add additional note to docs/understanding_qmk
* &unicode_map[index] → unicode_map + index
This avoids the issue of the compiler sometimes complaining about the array index being out of range
* Update docs/getting_started_make_guide
* Update method sections in docs/feature_unicode
* Remove chording as it is not documented, not used, and needs work.
* Make Leader Key an optional feature.
* Switch from `PREVENT_STUCK_MODIFIERS` to `STRICT_LAYER_RELEASE`
* Remove `#define PREVENT_STUCK_MODIFIERS` from keymaps.
* add process_terminal() and update links to other functions
* convert links to permalinks and add a few missing process_* functions
* update links in main text as well
