"""Run a PlatformIO ``extraScript`` against a captured SCons-env stand-in.
"""Run a PlatformIO library ``extraScript`` against a fake SCons env.
PlatformIO libraries occasionally configure per-target link/build state
via a Python ``extraScript`` declared in ``library.json``'s ``build``
section instead of static fields. The script runs under SCons during
PIO's build and mutates the active ``Environment`` (``env.Append``,
``env.Replace``, …) — chiefly to set ``LIBPATH``/``LIBS`` per chip MCU.
ESPHome's PIO→IDF converter doesn't run SCons, so these scripts were
previously ignored and any library
relying on them failed to link under ``toolchain: esp-idf``. This
module provides a small shim that ``exec``s an extra-script with a
fake ``env`` object, captures the common ``env.Append(...)`` calls,
and returns the captured vars so the caller can fold them back into
the library's generated CMakeLists.
Caveats
-------
* Only the ``env.Append`` API is captured. ``env.Replace``,
``env.Prepend``, ``env.AddPreAction``, SCons file generators, and any
arbitrary I/O are no-ops, logged once per method. Scripts that depend
on those will produce incomplete output.
* Running arbitrary Python from third-party libraries is a non-trivial
trust decision. The shim does no sandboxing — anything in the
script's process can run. Use only with libraries whose source you
trust.
The shim execs the script with a stand-in ``env``, captures ``env.Append``
calls (everything else is a logged no-op), and folds the result into the
library's build flags. No sandboxing: the script runs with full process
access, so it carries the same trust as the library's own source.
