#!/usr/bin/env python # coding=utf-8 # # This script helps installing tools required to use the ESP-IDF, and updating PATH # to use the installed tools. It can also create a Python virtual environment, # and install Python requirements into it. # It does not install OS dependencies. It does install tools such as the Xtensa # GCC toolchain and ESP32 ULP coprocessor toolchain. # # By default, downloaded tools will be installed under $HOME/.espressif directory # (%USERPROFILE%/.espressif on Windows). This path can be modified by setting # IDF_TOOLS_PATH variable prior to running this tool. # # Users do not need to interact with this script directly. In IDF root directory, # install.sh (.bat) and export.sh (.bat) scripts are provided to invoke this script. # # Usage: # # * To install the tools, run `idf_tools.py install`. # # * To install the Python environment, run `idf_tools.py install-python-env`. # # * To start using the tools, run `eval "$(idf_tools.py export)"` — this will update # the PATH to point to the installed tools and set up other environment variables # needed by the tools. # ### # # Copyright 2019 Espressif Systems (Shanghai) PTE LTD # # Licensed under the Apache License, Version 2.0 (the "License"); # you may not use this file except in compliance with the License. # You may obtain a copy of the License at # # http://www.apache.org/licenses/LICENSE-2.0 # # Unless required by applicable law or agreed to in writing, software # distributed under the License is distributed on an "AS IS" BASIS, # WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. # See the License for the specific language governing permissions and # limitations under the License. import json import os import subprocess import sys import argparse import re import platform import hashlib import tarfile import zipfile import errno import shutil import functools import copy from collections import OrderedDict, namedtuple try: import typing # noqa: F401 except ImportError: pass try: from urllib.request import urlretrieve except ImportError: from urllib import urlretrieve try: from exceptions import WindowsError except ImportError: class WindowsError(OSError): pass TOOLS_FILE = 'tools/tools.json' TOOLS_SCHEMA_FILE = 'tools/tools_schema.json' TOOLS_FILE_NEW = 'tools/tools.new.json' TOOLS_FILE_VERSION = 1 IDF_TOOLS_PATH_DEFAULT = os.path.join('~', '.espressif') UNKNOWN_VERSION = 'unknown' SUBST_TOOL_PATH_REGEX = re.compile(r'\${TOOL_PATH}') VERSION_REGEX_REPLACE_DEFAULT = r'\1' IDF_MAINTAINER = os.environ.get('IDF_MAINTAINER') or False TODO_MESSAGE = 'TODO' DOWNLOAD_RETRY_COUNT = 3 URL_PREFIX_MAP_SEPARATOR = ',' IDF_TOOLS_INSTALL_CMD = os.environ.get('IDF_TOOLS_INSTALL_CMD') IDF_TOOLS_EXPORT_CMD = os.environ.get('IDF_TOOLS_INSTALL_CMD') PYTHON_PLATFORM = platform.system() + '-' + platform.machine() # Identifiers used in tools.json for different platforms.
