Dynamic variables/templates for use in platformio.ini

[sticilface]

I'd like to define some variables that are constant between about 6 [env]. is this possible...

something like

[platformio]
src_dir = ./MyMelvanimate ; keeps arduino happy :)
data_dir = ./MyMelvanimate/data
env_default = esp12e-debug
test_var='-lstdc++ -Wl,-Tesp8266.flash.4m.ld -lc -I"/Users/amelvin/Arduino/esp8266/tools/sdk/libc/xtensa-lx106-elf/include" -L"/Users/amelvin/Arduino/esp8266/tools/sdk/libc/xtensa-lx106-elf/lib"'

then later

[env:debug]
platform = espressif
framework = arduino
board = esp12e
;build_flags = -lstdc++ -Wl,-Tesp8266.flash.4m.ld -lc -I"/Users/amelvin/Arduino/esp8266/tools/sdk/libc/xtensa-lx106-elf/include" -L"/Users/amelvin/Arduino/esp8266/tools/sdk/libc/xtensa-lx106-elf/lib" ;   -DDebug_ESPManager -DDEBUG_ESP_PORT=Serial -DDebugUDP ; -DDebugMelvanimate ;-DDEBUG_ESP_CORE -DDEBUG_ESP_WIFI
build_flags = $test_var; -lstdc++ -Wl,-Tesp8266.flash.4m.ld
board_flash_mode = qio
board_f_cpu = 160000000L
board_f_flash = 80000000L
lib_install = 13, 547, 89 ; 64 = arduinojson
upload_port = 192.168.1.70 ; nodemcu

thats great cheers. Was a question so moved it to the forum.

Why did you close this issue? That is a great feature for PaltformIO 3.0. I had the same idea 👍

Now, it should be 100% implemented.

[ivankravets]

I propose a next format of dynamic variables:

[common]
build_flags = -DHELLO -Icustom/inc

[env:uno_debug]
build_flags = -DDEBUG ${common.build_flags}

[env:uno_release]
build_flags = -DRELEASE ${common.build_flags}

[sticilface]

This looks great:)

[itsjustvenky]

Yes.. this is really a nice idea.a great feature indeed

Please re-test it with the latest development version http://docs.platformio.org/en/latest/installation.html#development-version
