Change the underlying command line handling:
- switch to a custom parser, inspired by redis / sds
- update terminalRegisterCommand signature, pass only bare minimum
- clean-up `help` & `commands`. update settings `set`, `get` and `del`
- allow our custom test suite to run command-line tests
- clean-up Stream IO to allow us to print large things into debug stream (for example, `eeprom.dump`)
- send parsing errors to the debug log
As a proof of concept, introduce `TERMINAL_MQTT_SUPPORT` and `TERMINAL_WEB_API_SUPPORT`
- MQTT subscribes to the `<root>/cmd/set` and sends response to the `<root>/cmd`. We can't output too much, as we don't have any large-send API.
- Web API listens to the `/api/cmd?apikey=...&line=...` (or PUT, params inside the body). This one is intended as a possible replacement of the `API_SUPPORT`. Internals introduce a 'task' around the AsyncWebServerRequest object that will simulate what WiFiClient does and push data into it continuously, switching between CONT and SYS.
Both are experimental. We only accept a single command and not every command is updated to use Print `ctx.output` object. We are also somewhat limited by the Print / Stream overall, perhaps I am overestimating the usefulness of Arduino compatibility to such an extent :)
Web API handler can also sometimes show only part of the result, whenever the command tries to yield() by itself waiting for something. Perhaps we would need to create a custom request handler for that specific use-case.
* emon: configure ratios without reboot
* settings: serialize() support
* debug: use vsnprintf from newlib, not from sdk
* settings/experimental: show defaults via `get`
* emon: override base methods, fix defaults
* sensor/emon: expose internal index calculation
- refactor configuration to use the correct index when accessing indexed
sensor methods. store index value on magnitude, refactor loops to
accomodate this new functionality
- rename slot(index) -> description(index), since we use 'slot' as
numeric value
- general conversion from .ino modules into a separate .cpp files
- clean-up internal headers, place libraries into .h. guard .cpp with _SUPPORT flags
- fix some instances of shared variables instead of public methods
- tweak build system to still build a single source file via os environment variable ESPURNA_BUILD_SINGLE_SOURCE
* debug: store boot log
* order
* roll single header
* hide when not implemented
* fix capacity check
* dependencies
* refactor names, can just use malloc
* settings formatting
* dbgBuf prefix
* show size
* release memory after buffer is displayed
* fix uptime unused warning, combine printer
* comments
* use arg flag instead of static to handle boot
* ci test fix
* Hide whole info() without debug
* typo
* cleanup setDebugOutput condition
- update every dynamicjsonbuffer with fixed size constructor argument
- change to ws callback registration to use a class builder (just cosmetic)
- test multiple ws data callbacks for each module
- remove some of the static strings in favour of ws data callback
- improve sensor ws callback data size, remove duplicated strings
- use static buffer in wsDebugSend
- postpone wsSend until loop, implement wsPost to allow other modules to queue message callbacks. remove Ticker based ws callbacks for data
- update WebUI files
- chain debugSend_P into basic _debugSend instead of duplicating code, pass va_list between them
- check if new[] call was successful
- when possible, use stack buffer and fallback to heap buffer only when it is more that 64 chars
* send all ws config at once on start
* reduce ws json overhead by creating message buffer manually
* use k:[values] instead of k1:value1, k2:value2 etc. for lists
