Walkthrough

Switches ESP-IDF venv and dependency handling to use the penv "uv" executable via penv_setup.get_executable_path; adds PLATFORMIO_DIR constant; locates LIB_SOURCE via platform.get_dir(); changes venv location to PLATFORMIO_DIR/penv/.espidf-{version} and verifies venv by resolving its Python executable.

Poem

I hopped through PLATFORMIO's turf so spry,
Found uv and penv beneath the sky.
A venv grew with a gentle shove,
Python answered — snug as a glove.
I wiggle my nose — the build says hi. 🐇✨

1609-1642: Harden venv creation & unify uv resolution across ESP-IDF builder

I’ve confirmed two distinct ways of locating the uv executable in builder/frameworks/espidf.py:

  • In install_python_deps() (around line 1490), UV_EXE is built from env.subst("$PYTHONEXE") + os.path.dirname()
  • In _create_venv() (lines 1614–1642), uv_path comes from get_executable_path(penv_dir, "uv")

To avoid silent failures and ensure consistent behavior:

  1. In _create_venv():

    • Immediately verify uv_path exists before invoking it.
    • Replace the assert on the Python executable with an explicit env.Exit(1) and stderr message.
     def _create_venv(venv_dir):
         penv_setup_path = os.path.join(platform.get_dir(), "builder")
         sys.path.insert(0, penv_setup_path)
    
         from penv_setup import get_executable_path
    
         penv_dir = os.path.join(PLATFORMIO_DIR, "penv")
         uv_path = get_executable_path(penv_dir, "uv")
  •   if not uv_path or not os.path.isfile(uv_path):
    
  •       sys.stderr.write(
    
  •           "Error: 'uv' executable not found in PlatformIO penv. "
    
  •           "Ensure penv_setup has installed uv or reinstall the platform.\n"
    
  •       )
    
  •       env.Exit(1)
    
      if os.path.isdir(venv_dir):
          …
      env.Execute(
          env.VerboseAction(
              '"%s" venv --clear --quiet "%s"' % (uv_path, venv_dir),
              "Creating a new virtual environment for IDF Python dependencies using uv",
          )
      )
    
      python_path = get_executable_path(venv_dir, "python")
    
  •   assert os.path.isfile(python_path), \
    
  •       "Error: Failed to create a proper virtual environment. Missing the Python executable!"
    
  •   if not python_path or not os.path.isfile(python_path):
    
  •       sys.stderr.write(
    
  •           "Error: Failed to create a proper virtual environment "
    
  •           "(Python executable missing).\n"
    
  •       )
    
  •       env.Exit(1)
    
    
    
  1. In install_python_deps():

    • Replace the custom UV_EXE derivation with the same get_executable_path() approach.
    • Import get_executable_path from penv_setup and point it at the shared penv directory.
     def install_python_deps():
  •   PYTHON_EXE = env.subst("$PYTHONEXE")
    
  •   UV_EXE = os.path.join(
    
  •       os.path.dirname(PYTHON_EXE),
    
  •       "uv" + (".exe" if IS_WINDOWS else "")
    
  •   )
    
  •   from penv_setup import get_executable_path
    
  •   PYTHON_EXE = env.subst("$PYTHONEXE")
    
  •   penv_dir = os.path.join(PLATFORMIO_DIR, "penv")
    
  •   UV_EXE = get_executable_path(penv_dir, "uv")
    
      def _get_installed_uv_packages(python_exe_path):
          …
    
    
    

By unifying both call sites on get_executable_path() you eliminate path drift, and by adding explicit existence checks plus consistent error exits you prevent opaque failures in CI or user environments.

85-85: Use PLATFORMIO_DIR consistently throughout the file

Good addition. For consistency and to avoid duplicate env lookups, reuse PLATFORMIO_DIR (introduced here) when computing the IDF venv path in get_idf_venv_dir() instead of calling env.subst("$PROJECT_CORE_DIR") again.

Proposed change outside this range (for get_idf_venv_dir):

def get_idf_venv_dir():
    idf_version = get_framework_version()
    return os.path.join(PLATFORMIO_DIR, "penv", f".espidf-{idf_version}")

1491-1523: Drop “uv” from the IDF venv dependencies

The PyPI “uv” package isn’t needed inside the IDF virtual environment—uv is a standalone CLI and is provided alongside the python executable rather than installed via pip in the target venv. You can remove it from the deps dict without impacting functionality.

• In builder/frameworks/espidf.py (around lines 1513–1516), update the deps block:

deps = {
-   "uv": ">=0.1.0",  # not needed inside the IDF venv
    "urllib3": "<2",
    "cryptography": "~=44.0.0",
    "pyparsing": ">=3.1.0,<4",
    "idf-component-manager": "~=2.2",
    "esp-idf-kconfig": "~=2.5.0"
}

• To confirm no other uv entries remain in the deps list, run:

rg -nP "^[ \t]*['\"]uv['\"][ \t]*:" builder/frameworks/espidf.py

351-366: LIB_SOURCE resolution via platform.get_dir() looks correct

Switching to platform.get_dir() for builder/build_lib resolves the path deterministically from the platform package root and decouples it from ProjectConfig. The flow that reshapes the environment for Arduino-only builds remains intact.

Refactor Python dependency installation to use a virtual environment and update UV executable path retrieval.

85-85: Rename PLATFORMIO_DIR to PIO_CORE_DIR to avoid confusion with PlatformIO’s own “PLATFORMIO_DIR” concept

This variable actually holds $PROJECT_CORE_DIR (PlatformIO core dir). Naming it PLATFORMIO_DIR is easy to conflate with PlatformIO’s “home” dir in docs and other code. Rename for clarity and update references.

Apply these focused diffs:

-PLATFORMIO_DIR = env.subst("$PROJECT_CORE_DIR")
+PIO_CORE_DIR = env.subst("$PROJECT_CORE_DIR")
-    penv_dir = os.path.join(PLATFORMIO_DIR, "penv")
+    penv_dir = os.path.join(PIO_CORE_DIR, "penv")
-    return os.path.join(PLATFORMIO_DIR, "penv", f".espidf-{idf_version}")
+    return os.path.join(PIO_CORE_DIR, "penv", f".espidf-{idf_version}")
-        penv_dir = os.path.join(PLATFORMIO_DIR, "penv")
+        penv_dir = os.path.join(PIO_CORE_DIR, "penv")

Also applies to: 1495-1495, 1568-1568, 1615-1615


1491-1496: Centralize uv resolution; avoid duplicating sys.path mutations

You resolve uv here and again in _create_venv by pushing builder/ onto sys.path and importing penv_setup each time. Centralizing this avoids path pollution and repetition. Also guarantees a single place to tweak bootstrap logic later.

Apply this minimal diff in-place:

-    penv_setup_path = os.path.join(platform.get_dir(), "builder")
-    sys.path.insert(0, penv_setup_path)
-    from penv_setup import get_executable_path
-
-    penv_dir = os.path.join(PLATFORMIO_DIR, "penv")
-    UV_EXE = get_executable_path(penv_dir, "uv")
+    UV_EXE = _get_uv_exe()

And add this helper once (outside this hunk), which safely avoids duplicate sys.path entries:

def _get_uv_exe():
    penv_setup_path = os.path.join(platform.get_dir(), "builder")
    if penv_setup_path not in sys.path:
        sys.path.insert(0, penv_setup_path)
    from penv_setup import get_executable_path
    penv_dir = os.path.join(PIO_CORE_DIR if 'PIO_CORE_DIR' in globals() else PLATFORMIO_DIR, "penv")
    return get_executable_path(penv_dir, "uv")

1610-1617: Use the centralized uv resolver and prefer explicit error handling over assert for venv verification

  • Reuse the _get_uv_exe() helper here.
  • Replace assert with a proper error path; asserts can be stripped with -O and don’t print stderr context in SCons.

Apply this diff:

-        penv_setup_path = os.path.join(platform.get_dir(), "builder")
-        sys.path.insert(0, penv_setup_path)
-
-        from penv_setup import get_executable_path
-
-        penv_dir = os.path.join(PLATFORMIO_DIR, "penv")
-        uv_path = get_executable_path(penv_dir, "uv")
+        uv_path = _get_uv_exe()
-        env.Execute(
+        env.Execute(
             env.VerboseAction(
                 '"%s" venv --clear --quiet --python "%s" "%s"' % (uv_path, env.subst("$PYTHONEXE"), venv_dir),
                 "Creating a new virtual environment for IDF Python dependencies using uv",
             )
         )
-        python_path = get_executable_path(venv_dir, "python")
-        
-        assert os.path.isfile(
-            python_path
-        ), "Error: Failed to create a proper virtual environment. Missing the Python executable!"
+        python_path = get_executable_path(venv_dir, "python")
+        if not os.path.isfile(python_path):
+            sys.stderr.write("Error: Failed to create a proper IDF virtual environment; Python not found at %s\n" % python_path)
+            env.Exit(1)

1497-1512: Compatibility of uv pip list JSON parsing is acceptable; guard for future format deviation

Parsing name/version from uv pip list --format=json is fine. You already catch JSONDecodeError/OSError. Optional: log UV_EXE version when the parse fails to make debugging easier if uv changes output format.


1568-1568: New venv location under core penv is fine; add optional detection/cleanup for legacy venvs

The change to install IDF’s Python virtualenv under
$PROJECT_CORE_DIR/penv/.espidf‐<version>
is safe and will be recreated on first use. As a small quality-of-life improvement, you can add a one-time check for legacy venvs (which were previously created directly under the core dir) and log a hint so users can delete them and reclaim disk space.

Here’s an example you could drop into your penv_setup logic:

import os, glob, logging

core_dir = PLATFORMIO_DIR  # env.subst("$PROJECT_CORE_DIR")
# Find any “.espidf-…” dirs not under the new penv folder
legacy = [
    d for d in glob.glob(os.path.join(core_dir, ".espidf-*"))
    if not d.startswith(os.path.join(core_dir, "penv"))
]
if legacy:
    logging.info(
        "Found legacy IDF venv(s): %s; consider removing them to reclaim disk space",
        legacy
    )

Or from the shell (adjust CORE_DIR as needed for your setup):

#!/usr/bin/env bash
# Replace with your actual core dir if not ~/.platformio
CORE_DIR="${PLATFORMIO_DIR:-$(platformio settings get project_core_dir)}"
# List any hidden .espidf-* dirs outside of penv/
fd -HI '^\.espidf-' "$CORE_DIR" -t d \
   ! -path "$CORE_DIR/penv/*" \
   -x echo {}

This will accurately locate any leftover .espidf-* venvs outside the new penv directory so users can clean them up.

Learning: In PlatformIO ESP32 platform builds, `semantic_version` is a dependency provided by PlatformIO itself and is guaranteed to be available when the build scripts run. The module is already imported at the top level in existing files like `builder/frameworks/espidf.py`, so lazy-loading it is unnecessary.

353-365: LIB_SOURCE via platform.get_dir() is a good move

Switching to platform.get_dir() to resolve builder/build_lib removes reliance on ProjectConfig and is more robust. The copy-tree guard looks sane.


1541-1551: Nice: installing missing packages only; quotes/constraints look correct

Selective install using uv pip --python and quoting each "pkg{spec}" looks good and OS-safe. This aligns with the repo’s pattern of executing Python via explicit paths (per past learnings).


1552-1559: Windows-only windows-curses install via uv is correct

Good conditional and reuse of uv pip to keep all installs within the IDF venv.

24-60: Dynamic import of penv_setup: add defensive checks to fail fast if the module file/spec/loader is missing

Good call switching to importlib and centralizing get_executable_path. Add explicit checks so failures surface with actionable messages instead of AttributeError later.

 _penv_setup_file = os.path.join(platform.get_dir(), "builder", "penv_setup.py")
-_spec = importlib.util.spec_from_file_location("penv_setup", _penv_setup_file)
-_penv_setup = importlib.util.module_from_spec(_spec)
-_spec.loader.exec_module(_penv_setup)  # type: ignore[attr-defined]
-get_executable_path = _penv_setup.get_executable_path
+if not os.path.isfile(_penv_setup_file):
+    sys.stderr.write(f"Error: Missing penv_setup.py at {_penv_setup_file}\n")
+    env.Exit(1)
+_spec = importlib.util.spec_from_file_location("penv_setup", _penv_setup_file)
+if _spec is None or _spec.loader is None:
+    sys.stderr.write("Error: Failed to load spec for penv_setup module\n")
+    env.Exit(1)
+_penv_setup = importlib.util.module_from_spec(_spec)
+_spec.loader.exec_module(_penv_setup)  # type: ignore[attr-defined]
+get_executable_path = _penv_setup.get_executable_path

1498-1500: Fail fast if uv executable is not resolvable

Since subsequent steps rely on uv, surface a clear error early rather than failing deeper in subprocess calls.

-def _get_uv_exe():
-    return get_executable_path(os.path.join(PLATFORMIO_DIR, "penv"), "uv")
+def _get_uv_exe():
+    uv_path = get_executable_path(os.path.join(PLATFORMIO_DIR, "penv"), "uv")
+    if not uv_path or not os.path.isfile(uv_path):
+        sys.stderr.write(
+            "Error: 'uv' executable not found in PlatformIO penv. "
+            "Ensure builder/penv_setup.py installed it correctly.\n"
+        )
+        env.Exit(1)
+    return uv_path

1503-1568: Normalize package-name keys to avoid case-sensitivity mismatches

uv pip list can return names with varying case. Normalize to lower-case once to make membership checks robust (especially for windows-curses).

-        for p in packages:
-            result[p["name"]] = pepver_to_semver(p["version"])
+        for p in packages:
+            result[p["name"].lower()] = pepver_to_semver(p["version"])

1618-1645: Venv creation and verification: prefer explicit error handling over assert

Asserts can be stripped with Python -O. Use an explicit check and env.Exit to guarantee the error is raised. Also, the user-facing message already mentions uv; good clarity.

-        # Verify that the venv was created successfully by checking for Python executable
-        python_path = get_executable_path(venv_dir, "python")
-        
-        assert os.path.isfile(
-            python_path
-        ), "Error: Failed to create a proper virtual environment. Missing the Python executable!"
+        # Verify that the venv was created successfully by checking for Python executable
+        python_path = get_executable_path(venv_dir, "python")
+        if not python_path or not os.path.isfile(python_path):
+            sys.stderr.write(
+                "Error: Failed to create a proper virtual environment. "
+                "Missing the Python executable!\n"
+            )
+            env.Exit(1)

92-92: PLATFORMIO_DIR constant: LGTM

Centralizing the core dir via env.subst("$PROJECT_CORE_DIR") improves readability and reuse downstream.


1575-1577: Venv location under PLATFORMIO_DIR/penv/.espidf-{version}: LGTM

Keeps IDF envs co-located with PlatformIO penv. Matches prior conventions and avoids user-global pollution.


1503-1519: uv-based deps install: approach looks solid

  • Single-shot install per batch is efficient.
  • Constraints for urllib3/cryptography/pyparsing/idf-component-manager/esp-idf-kconfig are explicit and reproducible.
  • Windows-specific windows-curses handled.

No blockers from me here.

Also applies to: 1550-1567


513-528: IDF_TOOLS_PATH sanitization aligns with prior preference

Unsetting IDF_TOOLS_PATH in the IDF env avoids leakage of user overrides, matching the project preference captured in prior PRs.


361-374: Verified: builder/build_lib directory exists; LIB_SOURCE resolution is correct

Confirmed that builder/build_lib/ is present under the platform root, so the switch to platform.get_dir() for locating build_lib is valid and robust against varying install layouts.

env.Replace uses this path appropriately—no further changes needed.
