compile_pip_requirements(name, extra_args, visibility, requirements_in, requirements_txt, tags, kwargs)
Generates targets for managing pip dependencies with pip-compile.
By default this rules generates a filegroup named "[name]" which can be included in the data
of some other compile_pip_requirements rule that references these requirements
(e.g. with -r ../other/requirements.txt).
It also generates two targets for running pip-compile:
- validate with
bazel test <name>_test - update with
bazel run <name>.update
PARAMETERS
| Name | Description | Default Value |
|---|---|---|
| name | base name for generated targets, typically "requirements" | none |
| extra_args | passed to pip-compile | [] |
| visibility | passed to both the _test and .update rules | ["//visibility:private"] |
| requirements_in | file expressing desired dependencies | None |
| requirements_txt | result of "compiling" the requirements.in file | None |
| tags | tagging attribute common to all build rules, passed to both the _test and .update rules | None |
| kwargs | other bazel attributes passed to the "_test" rule | none |
package_annotation(additive_build_content, copy_files, copy_executables, data, data_exclude_glob, srcs_exclude_glob)
Annotations to apply to the BUILD file content from package generated from a pip_repository rule.
PARAMETERS
| Name | Description | Default Value |
|---|---|---|
| additive_build_content | Raw text to add to the generated BUILD file of a package. |
None |
| copy_files | A mapping of src and out files for @bazel_skylib//rules:copy_file.bzl |
{} |
| copy_executables | A mapping of src and out files for @bazel_skylib//rules:copy_file.bzl. Targets generated here will also be flagged as executable. |
{} |
| data | A list of labels to add as data dependencies to the generated py_library target. |
[] |
| data_exclude_glob | A list of exclude glob patterns to add as data to the generated py_library target. |
[] |
| srcs_exclude_glob | A list of labels to add as srcs to the generated py_library target. |
[] |
pip_install(requirements, name, kwargs)
Accepts a requirements.txt file and installs the dependencies listed within.
Those dependencies become available in a generated requirements.bzl file.
This macro runs a repository rule that invokes pip. In your WORKSPACE file:
pip_install(
requirements = ":requirements.txt",
)You can then reference installed dependencies from a BUILD file with:
load("@pip//:requirements.bzl", "requirement")
py_library(
name = "bar",
...
deps = [
"//my/other:dep",
requirement("requests"),
requirement("numpy"),
],
)Note that this convenience comes with a cost. Analysis of any BUILD file which loads the requirements helper in this way will cause an eager-fetch of all the pip dependencies, even if no python targets are requested to be built. In a multi-language repo, this may cause developers to fetch dependencies they don't need, so consider using the long form for dependencies if this happens.
In addition to the requirement macro, which is used to access the py_library
target generated from a package's wheel, the generated requirements.bzl file contains
functionality for exposing entry points as py_binary targets.
load("@pip_deps//:requirements.bzl", "entry_point")
alias(
name = "pip-compile",
actual = entry_point(
pkg = "pip-tools",
script = "pip-compile",
),
)Note that for packages whose name and script are the same, only the name of the package
is needed when calling the entry_point macro.
load("@pip_deps//:requirements.bzl", "entry_point")
alias(
name = "flake8",
actual = entry_point("flake8"),
)PARAMETERS
| Name | Description | Default Value |
|---|---|---|
| requirements | A 'requirements.txt' pip requirements file. | none |
| name | A unique name for the created external repository (default 'pip'). | "pip" |
| kwargs | Keyword arguments passed directly to the pip_repository repository rule. |
none |
pip_parse(requirements_lock, name, kwargs)
Accepts a locked/compiled requirements file and installs the dependencies listed within.
Those dependencies become available in a generated requirements.bzl file.
This macro runs a repository rule that invokes pip. In your WORKSPACE file:
load("@rules_python//python:pip.bzl", "pip_parse")
pip_parse(
name = "pip_deps",
requirements_lock = ":requirements.txt",
)
load("@pip_deps//:requirements.bzl", "install_deps")
install_deps()You can then reference installed dependencies from a BUILD file with:
load("@pip_deps//:requirements.bzl", "requirement")
py_library(
name = "bar",
...
deps = [
"//my/other:dep",
requirement("requests"),
requirement("numpy"),
],
)In addition to the requirement macro, which is used to access the generated py_library
target generated from a package's wheel, The generated requirements.bzl file contains
functionality for exposing entry points as py_binary targets as well.
load("@pip_deps//:requirements.bzl", "entry_point")
alias(
name = "pip-compile",
actual = entry_point(
pkg = "pip-tools",
script = "pip-compile",
),
)Note that for packages whose name and script are the same, only the name of the package
is needed when calling the entry_point macro.
load("@pip_deps//:requirements.bzl", "entry_point")
alias(
name = "flake8",
actual = entry_point("flake8"),
)PARAMETERS
| Name | Description | Default Value |
|---|---|---|
| requirements_lock | A fully resolved 'requirements.txt' pip requirement file containing the transitive set of your dependencies. If this file is passed instead of 'requirements' no resolve will take place and pip_repository will create individual repositories for each of your dependencies so that wheels are fetched/built only for the targets specified by 'build/run/test'. | none |
| name | The name of the generated repository. The generated repositories containing each requirement will be of the form <name>_<requirement-name>. | "pip_parsed_deps" |
| kwargs | Additional keyword arguments for the underlying pip_repository rule. |
none |
pip_repositories()
Obsolete macro to pull in dependencies needed to use the pip_import rule.
