The embedded 40250 script layer needs its own interpreter on five platforms. 2.7 is end-of-life, so nothing can be fetched from the target SDKs and the source is vendored (official 2.7.18 tarball, trimmed to 25MB; Lib/ stays for step 3's python27.zip). cpython-2.7.18/CMakeLists.txt builds one `mtpython` static library from exactly the 133 objects the reference libpython2.7.a contains, off by default behind -DMTGODOT_EMBED_PYTHON=ON. The source list and the built-in module table (config/config.c, 39 entries) are shared; pyconfig.h is a probe result and is not, so each platform keeps its own under config/<platform>/, regenerated by tools/py_embed/gen_pyconfig.sh and checked against the shared table. Three vendor patches, documented in docs/THIRD-PARTY.md: configure/configure.ac learn arm64 on macOS, and posixmodule.c undefines the process-control calls it hard-defines past pyconfig.h when building for iOS. macOS (ctest python.embed: every builtin imports, codecs and pickle work off the vendored Lib/), Android arm64 and iOS arm64 build. Linux needs a Linux host and Windows needs a MinGW-vs-MSVC decision; both are noted for step 4. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

bits shared by the stringobject and unicodeobject implementations (and

possibly other modules, in a not too distant future).

--------------------------------------------------------------------
|
|
the following defines used by the different modules:
|
|
|
|
STRINGLIB_CHAR
|
|
|
|
the type used to hold a character (char or Py_UNICODE)
|
|
|
|
STRINGLIB_EMPTY
|
|
|
|
a PyObject representing the empty string, only to be used if
|
|
STRINGLIB_MUTABLE is 0
|
|
|
|
Py_ssize_t STRINGLIB_LEN(PyObject*)
|
|
|
|
returns the length of the given string object (which must be of the
|
|
right type)
|
|
|
|
PyObject* STRINGLIB_NEW(STRINGLIB_CHAR*, Py_ssize_t)
|
|
|
|
creates a new string object
|
|
|
|
STRINGLIB_CHAR* STRINGLIB_STR(PyObject*)
|
|
|
|
returns the pointer to the character data for the given string
|
|
object (which must be of the right type)
|
|
|
|
int STRINGLIB_CHECK_EXACT(PyObject *)
|
|
|
|
returns true if the object is an instance of our type, not a subclass
|
|
|
|
STRINGLIB_MUTABLE
|
|
|
|
must be 0 or 1 to tell the cpp macros in stringlib code if the object
|
|
being operated on is mutable or not
