Dynamic build_flags in platformio.ini / UNIX_TIME

[livello]

Have this bash file to set up build flags:

#! /bin/bash

usage:

first make your own copy of template

cp build_flags_template.sh my_build_flags.sh

then edit, change or comment something

nano my_build_flags.sh

and source it

source my_build_flags.sh

echo “==============================================Custom build flags are:=====================================================”
export FLAGS=“-DMY_CONFIG_SERVER=lazyhome.ru”
export FLAGS=“$FLAGS -DWATCH_DOG_TICKER_DISABLE”
export FLAGS=“$FLAGS -DUSE_1W_PIN=12”
export FLAGS=“$FLAGS -DSD_CARD_INSERTED”
export FLAGS=“$FLAGS -DSERIAL_BAUD=115200”
export FLAGS=“$FLAGS -DWiz5500”
export FLAGS=“$FLAGS -DDISABLE_FREERAM_PRINT”
export FLAGS=“$FLAGS -DCUSTOM_FIRMWARE_MAC=de:ad:be:ef:fe:00”
export FLAGS=“$FLAGS -DDMX_DISABLE”
export FLAGS=“$FLAGS -DMODBUS_DISABLE”
export FLAGS=“$FLAGS -DOWIRE_DISABLE”
export FLAGS=“$FLAGS -DAVR_DMXOUT_PIN=18”
export FLAGS=“$FLAGS -DLAN_INIT_DELAY=2000”
export FLAGS=“$FLAGS -DCONTROLLINO”
export FLAGS=“$FLAGS -DESP_WIFI_AP=MYAP”
export FLAGS=“$FLAGS -DESP_WIFI_PWD=MYPWD”
export PLATFORMIO_BUILD_FLAGS=“$FLAGS”
echo PLATFORMIO_BUILD_FLAGS=$PLATFORMIO_BUILD_FLAGS
echo “==============================================Custom build flags END=====================================================”
unset FLAGS

Can we replace this with python script?
I tried your code, with this directiive in my platformio.ini
extra_scripts = pre:my_build_flags.py
but it does not change build flags.

The reason is to build project from IDE, deal with errors there, having python scripts for every set of build flags.
