ESPIDF v3.3 requires "pyparsing"

Using latest develop branch the following is observed while building:

generate_project_ld_script([".pio\build\pcb_oled_sh1106\esp32.project.ld"], ....... 
Traceback (most recent call last):
  File ".....platformio\packages\framework-espidf\tools\ldgen\ldgen.py", line 22, in <module>
    from fragments import FragmentFileModel
  File "......platformio\packages\framework-espidf\tools\ldgen\fragments.py", line 20, in <module>
    from sdkconfig import SDKConfig
  File ".....platformio\packages\framework-espidf\tools\ldgen\sdkconfig.py", line 18, in <module>
    from pyparsing import Word, printables, Combine, Literal, hexnums, quotedString, Optional, nums, removeQuotes, oneOf, Group, infixNotation, opAssoc
ImportError: No module named pyparsing

(above has been pruned to show only the required pieces)

After resolving the above by running “pip install pyparsing” in the penv/Scripts directory the following is observed:

IOError:.....platformio\packages\framework-espidf\Kconfig:59: Could not open '.......platformio\packages\framework-espidf\components\app_update\Kconfig.projbuild#......platformio\packages\framework-espidf\components\bootloader\Kconfig.projbuild#......platformio\packages\framework-espidf\components\esptool_py\Kconfig.projbuild#.....platformio\packages\framework-espidf\components\partition_table\Kconfig.projbuild' (ENOENT: No such file or directory). Perhaps the $srctree environment variable (which was unset) is set incorrectly. Note that the current value of $srctree is saved when the Kconfig instance
is created (for consistency and to cleanly separate instances). Also note that e.g. $FOO in a 'source' statement does not refer to the environment variable FOO, but rather to the Kconfig Symbol FOO (which would commonly have
'option env="FOO"' in its definition).

The above is due to Windows not defining IFS in the env and the default setting being " \t\n" (space, tab, newline) inside kconfiglib.py.

Using space instead of # resolves this issue and building is successful.

@valeros FYI…

Has the kconfiglib.py update been sent to ESP-IDF? If not, please do so. In the meantime, can we switch from # to tab (\t)? A local test using the GIT version with tab instead of # works from my tests.

pyparsing is now part of the framework package. In case you want to use framework directly from the repository please install this module in the IDE manually using pip.
