The IDF Component Manager is a tool that ensures the correct versions of all components required for a successful build are present in your ESP-IDF project.
- The Component Manager downloads the dependencies for your project automatically during a
CMakerun. - The components can be sourced either from the ESP Component Registry or from a Git repository.
- A list of components can be found at https://components.espressif.com/
See CONTRIBUTING.md
- Offical Documentation at docs.espressif.com
- The Python Package Index project page https://pypi.org/project/idf-component-manager/
- The Component Manager section in the ESP-IDF Programming Guide
You can install the development version of the Component Manager from the main branch of this repository:
On Linux/macOS:
Go to the directory with your ESP-IDF installation and run:
# activate ESP-IDF environment
source ./export.sh # or . ./export.fish, if you use fish shell
# remove old version of the Component Manager
python -m pip uninstall -y idf-component-manager
# install the development version (from the main branch)
python -m pip install git+https://github.com/espressif/idf-component-manager.git@mainOn Windows:
Run ESP-IDF PowerShell Environment or ESP-IDF Command Prompt (cmd.exe) from the Start menu and run the following command:
# remove old version of the Component Manager
python -m pip uninstall -y idf-component-manager
# install the development version (from the main branch)
python -m pip install git+https://github.com/espressif/idf-component-manager.git@mainThe Component Manager can be explicitly disabled by setting IDF_COMPONENT_MANAGER environment variable to 0.
You can add idf_component.yml manifest files with the list of dependencies to any component in your project.
IDF Component Manager will download dependencies automatically during the project build process.
When CMake configures the project (e.g. idf.py reconfigure) Component Manager does a few things:
- Processes
idf_component.ymlmanifests for every component in the project - Creates a
dependencies.lockfile in the root of the project with a full list of dependencies - Downloads all dependencies to the
managed_componentsdirectory
The Component Manager won't try to regenerate dependencies.lock or download any components if manifests, lock file, and content of managed_component directory weren't modified since the last successful build.
All dependencies are defined in the manifest file.
dependencies:
# Required IDF version
idf: ">=4.1"
# For components maintained by Espressif only name can be used.
# Same as `espressif/component`
component:
version: "~2.0.0"
# Or in a shorter form
component2: ">=1.0.0"
# For 3rd party components :
username/component:
version: "~1.0.0"
# For transient dependencies `public` flag can be set.
public: true
anotheruser/component: "<3.2.20"
# For components hosted on non-default registry:
company_user/component:
version: "~1.0.0"
registry_url: "https://componentregistry.company.com"
# For components in git repository:
test_component:
path: test_component
git: ssh://git@gitlab.com/user/components.git
# For test projects during component development
# components can be used from a local directory
# with relative or absolute path
some_local_component:
path: ../../projects/component
# For optional dependencies
optional_component:
version: "~1.0.0"
rules: # will add "optional_component" only when all if clauses are True
- if: "idf_version >=3.3,<5.0" # supports all SimpleSpec grammars (https://python-semanticversion.readthedocs.io/en/latest/reference.html#semantic_version.SimpleSpec)
- if: "target in [esp32, esp32c3]" # supports boolean operator ==, !=, in, not in.
# For example of the component
namespace/component_with_example:
version: "~1.0.0" # if there is no `override_path` field, use component from registry
override_path: "../../" # use component in a local directory, not from registry
namespace/no_required_component:
version: "*"
require: no # Download component but don't add it as a requirement
namespace/pre_release_component:
version: "*"
pre_release: true # Allow downloading of pre-release versionsBy default, information about available versions of components not cached. If you make many requests to the registry from one machine, you can enable caching by setting IDF_COMPONENT_API_CACHE_EXPIRATION_MINUTES environment variable to the number of minutes to cache the data.
You can add links to the idf_component.yml file to the root of the manifest:
url: "https://example.com/homepage" # URL of the component homepage
repository: "https://gitexample.com/test_project" # URL of the public repository with component source code, i.e GitHub, GitLab, etc.
documentation: "https://example.com/documentation" # URL of the component documentation
issues: "https://git.example.com/test_project/tracker" # URL of the issue tracker
discussion: "https://discord.example.com/test_project" # URL of the component discussion, i.e. Discord, Gitter, forum, etc.A link should be a correct HTTP(S) URL like https://example.com/path except the repository field,
it is expected to be a valid Git remote URL.
To add examples to your component, place them in the examples directory inside your component.
Examples are discovered recursively in subdirectories at this path.
A directory with CMakeLists.txt that registers a project is considered as an example.
You can specify custom example paths for uploading them to the component registry.
For that, add examples field to the root of the manifest:
examples:
- path: ../some/path
- path: ../some/other_path
# - path: examples/some_example # this example will be discovered automatically| Variable | Default value (or example for required) | Description |
|---|---|---|
| IDF_COMPONENT_API_TOKEN | API token to access the component registry | |
| IDF_COMPONENT_REGISTRY_URL | https://components.espressif.com/ | URL of the default component registry |
| IDF_COMPONENT_STORAGE_URL | https://components-file.espressif.com/ | URL of the default file storage server |
| IDF_COMPONENT_PROFILE | default | Profile in the config file to use |
| IDF_COMPONENT_CACHE_PATH | * Depends on OS | Cache directory for Component Manager |
| IDF_COMPONENT_VERSION_PROCESS_TIMEOUT | 300 | Timeout in seconds to wait for component processing |
| IDF_COMPONENT_OVERWRITE_MANAGED_COMPONENTS | 0 | Overwrite files in the managed_component directory, even if they have been modified by the user |
| IDF_COMPONENT_SUPPRESS_UNKNOWN_FILE_WARNINGS | 0 | Ignore unknown files in managed_components directory |
| IDF_COMPONENT_CHECK_NEW_VERSION | 1 | Check for new versions of components |
| IDF_COMPONENT_VERIFY_SSL | 1 | Verify SSL certificates when making requests to the registry, set it 0 to disable or provide a CA bundle path |
| IDF_COMPONENT_CACHE_HTTP_REQUESTS | 1 | Cache HTTP requests to the registry during runtime, set it 0 to disable |
