There are two execution orders for extra scripts:
PRE - executes before the main script of Development Platforms
POST - executes after the main script of Development Platforms
Multiple extra scripts are allowed. Please split them via “, ” (comma + space) in the same line or use multi-line values.
For example, in “platformio.ini” (Project Configuration File):
[env:my_env_1]
platform = ...
; Defaults to POST script since no prefix is used
extra_scripts = post_extra_script.py
[env:my_env_2]
platform = ...
extra_scripts =
pre:pre_extra_script.py
post:post_extra_script1.py
post_extra_script2.py
This option can also be set by the global environment variable PLATFORMIO_EXTRA_SCRIPTS.
