`-mD` is not an option...
`-M -MF $file` can be used together with `-E` to generate a small
makefile-like generator (does not include any compiler flags!) for the
target file so we know which files it would use during compilation
cannot depend on checkprogsize, since it depends on .elf and not .bin
also, compare with the block-aligned size
add notes about reserved space
warning might become annoying, though :)
store objcopy of these extra symbols and .map from the linker
distribution will have an extra debug .zip file that could be used with
the exception decoder
also fixes relative paths in the build-and-copy
(although, yet again loses the pio target in the gui)
Generate resulting .cpp in the $BUILD_DIR, no need for atexit
Register middleware only once, there's no need to manually walk the
project directory since fnmatch.fnmatch(...) supports globs
Provide a SCons Action instead of simple function, so there's a way to
generate things on demand via command line
```
$ pio run -e $env -t .pio/build/$env/espurna_single_source/src/main.cpp
```
- just pass `-include ${cfg}` to the compiler instead of a
temporary custom.h. also do `-DDEVICE=...` and `-DMANUFACTURER=...`
- rework test_build to print using `logging` module
- report leftover configurations, after the failed one exits
- prettify the output and highlight relevant info instead of the whole lines
- provide a queue for the outgoing messages, don't depend on the MQTT
callback implementation details and always postpone the actual transfer.
- generate user input parsers using re2c, adds special PlatformIO build handlers
- add terminal command to show GPIO info and send a simple payload
- rework button<->action presets into value<->terminal command presets and custom ones
through the use of `irCmd<VALUE>` settings, where the VALUE is taken from the simple payload
(yet, it does not understand repeated codes, but that's something to add later *or* use rpnlib)
- add tx message integration for the relay module via `irRelayOn#` and `irRelayOff#`
- rework simple payload to include 'repeats' value for the 'IRsend::send()'
also adds internal 'series', 'delay' and includes full 64bit 'value'
(as uppercase HEX, instead of decimal)
- rework raw payload to use 'series' instead of 'repeats', and provide a
clear distinction between the usec time and the options of the message
by moving the required options to the front and separating them using ':'
(just like the simple variant)
- make RX and TX pin a runtime setting, make RX and TX support a build flag
- small test framework to check whether internal string encode<->decode works
Also updates the hexEncode & hexDecode implementations to use
'iterators' instead of just pointer + index.
