Hi
I would like to add the build count to the build_flags inside the platformio.ini.
this is a way to control the OTA update via webserver on the esp8266.
So far all my tries are failing.
I believe that I somehow miss the right syntax.
the command: git rev-list HEAD --count
is working on cli level inside the IDE.
platformio.ini
[global]
build_flags = -D VERBOSE
[exec_command]
build_flags = !echo $(git rev-list HEAD --count)
[env:trial]
platform = espressif8266
board = huzzah
build_flags = -D VERSION=${exec_command.build_flags}
framework = arduino
When starting the run I got this as the output:
cli output
pio run -e trial
[Sun Dec 18 17:33:40 2016] Processing trial (platform: espressif8266, board: huzzah, framework: arduino, build_flags: -D VERSION=!echo $(git rev-
list HEAD --count))
Verbose mode can be enabled via -v, --verbose
option
Collected 30 compatible libraries
Looking for dependencies…
