extra_configs

Type: String (Pattern) | Multiple: Yes

This option allows extending a base “platformio.ini” (Project Configuration File) with extra configuration files. The format and rules are the same as for the “platformio.ini” (Project Configuration File). A name of the configuration file can be any.

extra_configs can be a single path to an extra configuration file or a list of them. Please note that you can use Unix shell-style wildcards:

Pattern	Meaning
*	matches everything
?	matches any single character
[seq]	matches any character in seq
[!seq]	matches any character not in seq

Note

If you declare the same pair of “group” + “option” in an extra configuration file which was previously declared in a base “platformio.ini” (Project Configuration File), it will be overwritten with a value from extra configuration.

Example

Base “platformio.ini”

[platformio]
extra_configs =
  extra_envs.ini
  extra_debug.ini

; Global data for all [env:***]
[env]
platform = espressif32
framework = espidf

; Custom data group
; can be use in [env:***] via ${common.***}
[common]
debug_flags = -D RELEASE
lib_flags = -lc -lm

[env:esp-wrover-kit]
board = esp-wrover-kit
build_flags = ${common.debug_flags}

“extra_envs.ini”

[env:esp32dev]
board = esp32dev
build_flags = ${common.lib_flags} ${common.debug_flags}

[env:lolin32]
platform = espressif32
framework = espidf
board = lolin32
build_flags = ${common.debug_flags}

“extra_debug.ini”

# Override base "common.debug_flags"
[common]
debug_flags = -D DEBUG=1

[env:lolin32]
build_flags = -Og

After a parsing process, configuration state will be the next:

[common]
debug_flags = -D DEBUG=1
lib_flags = -lc -lm

[env:esp-wrover-kit]
platform = espressif32
framework = espidf
board = esp-wrover-kit
build_flags = ${common.debug_flags}

[env:esp32dev]
platform = espressif32
framework = espidf
board = esp32dev
build_flags = ${common.lib_flags} ${common.debug_flags}

[env:lolin32]
platform = espressif32
framework = espidf
board = lolin32
build_flags = -Og
