package-auto-assembler 0.5.17

A tool to automate package creation within ci based on just .py and optionally .ipynb file.

Package auto assembler

package-auto-assembler is a tool that meant to streamline creation of single module packages. Its primary goal is to automate as many aspects of python package creation as possible, thereby shortening the development cycle of reusable components and maintaining a high standard of quality for reusable code.

With package-auto-assembler, you can simplify the package creation process to the point where it can be seamlessly triggered within CI/CD pipelines, requiring minimal setup and preparation for new modules.

Key features

• Set up new Python packaging repositories for Github and Azure DevOps.
• Create new packages dynamically, reducing manual effort.
• Check module dependencies for vulnerabilities and unexpected licenses.
• Run FastAPI and Streamlit apps directly from packages created with this tool.
• Extract artifacts and files packaged alongside code.
• Show detailed information about installed packages made with the tool.
• Automatically assemble release notes based on commit messages.
• Extract requirements automatically from .py files without maintaining separate requirements.txt.

The following includes additional details to how some features of the packages work with examples that involve internal components. Even though using the package this way is very much possible, cli interface is recomended.

    ImportMappingHandler, RequirementsHandler, MetadataHandler, \
        LocalDependaciesHandler, LongDocHandler, SetupDirHandler, \
            ReleaseNotesHandler, MkDocsHandler, PackageAutoAssembler, \

1. Package versioning

Package versioning within paa is done based on semantic versioning.

major.minor.patch

By default, patch is updated, but the minor and major could also be update based on, for example, commit messages or manually from the log file.

Package auto assembler does try to pull latest version from package storage, but in case of failure uses version logs stored in .paa/tracking.

Initialize VersionHandler

pv = VersionHandler(
    # required
    versions_filepath = '../tests/package_auto_assembler/other/lsts_package_versions.yml',
    log_filepath = '../tests/package_auto_assembler/other/version_logs.csv',
    # optional
    default_version = "0.0.1")

Add new package

pv.add_package(
    package_name = "new_package",
    # optional
    version = "0.0.1"
)

Update package version

pv.increment_patch(
    package_name = "new_package"
)
## for not tracked package
pv.increment_patch(
    package_name = "another_new_package",
    # optional
    default_version = "0.0.1"
)

There are no known versions of 'another_new_package', 0.0.1 will be used!

Display current versions and logs

pv.get_versions(
    # optional
    versions_filepath = '../tests/package_auto_assembler/other/lsts_package_versions.yml'
)

{'another_new_package': '0.0.1', 'new_package': '0.0.2'}

pv.get_version(
    package_name='new_package'
)

'0.0.2'

pv.get_logs(
    # optional
    log_filepath = '../tests/package_auto_assembler/other/version_logs.csv'
)

<style scoped> .dataframe tbody tr th:only-of-type { vertical-align: middle; }

.dataframe tbody tr th {
    vertical-align: top;
}

.dataframe thead th {
    text-align: right;
}

</style>

	Timestamp	Package	Version
0	2024-07-29 03:26:39	new_package	0.0.1
1	2024-07-29 03:26:40	new_package	0.0.2
2	2024-07-29 03:26:40	another_new_package	0.0.1

Flush versions and logs

pv.flush_versions()
pv.flush_logs()

Get latest available version with pip

pv.get_latest_pip_version(package_name = 'package-auto-assembler')

'0.3.1'

2. Import mapping

Install and import names of dependencies may vary. The mapping files maps import names to install names so that requirements extraction from .py files is possible. Some of the mapping are packaged and would not need to provided, but in case a dependency used within new package was not inluded, it is possible to augment default mapping through .paa/package_mapping.json

Initialize ImportMappingHandler

im = ImportMappingHandler(
    # required
    mapping_filepath = "../env_spec/package_mapping.json"
)

Load package mappings

im.load_package_mappings(
    # optional
    mapping_filepath = "../env_spec/package_mapping.json"
)

{'PIL': 'Pillow',
 'bs4': 'beautifulsoup4',
 'fitz': 'PyMuPDF',
 'attr': 'attrs',
 'dotenv': 'python-dotenv',
 'googleapiclient': 'google-api-python-client',
 'google_auth_oauthlib': 'google-auth-oauthlib',
 'sentence_transformers': 'sentence-transformers',
 'flask': 'Flask',
 'stdlib_list': 'stdlib-list',
 'sklearn': 'scikit-learn',
 'yaml': 'pyyaml',
 'package_auto_assembler': 'package-auto-assembler',
 'git': 'gitpython'}

3. Extracting and merging requirements

Maintaining requirements is much simpler, when done automatically based on the .py files.

The actual requirements files is still constructed. Standard libraries are not added, others are added with their versions, if specified. Local files are also used as dependencies, from which imports are extracted as well.

For example:

import os
import pandas
import attr #>=22.2.0
from .components.local_dep import *

produces

pandas
attrs >=22.2.0
yaml

as requirements file, where yaml is extracted from local_dep.py file.

Checking dependecies for vulnerabilities is usefull and it is done with pip audit which is integrated into the paa package and is used by default.

Optional requirements for extras_require could be probided the same way normal requirements are, but each like that contains an import like that should be commented out in a special way, starting with #!, for example:

import os
import pandas
import attr #>=22.2.0
#! import hnswlib #==0.8.0

produces

pandas
attrs >=22.2.0
hnswlib==0.8.0; extra == "hnswlib"

Sometimes automatic translation of import names to install names via package_mapping.json, for packages where these names differ, may not be enough. A manual overwrite can be done with exlusion of some dependencies from automatic extraction pipeline with #- comment next to import and #@ prefix before text that is intended to end up in an equivalent requirements file, for example:

import os
import pandas
import attr #>=22.2.0
import tensorflow #-
#@ tensorflow-gpu

produces

pandas
attrs >=22.2.0
tensorflow-gpu

Initialize RequirementsHandler

rh = RequirementsHandler(
    # optional/required later
    module_filepath = "../tests/package_auto_assembler/other/example_module.py",
    package_mappings = {'PIL': 'Pillow',

Read requirements

rh.read_requirements_file(
    # required
    requirements_filepath = "../tests/package_auto_assembler/other/requirements_example_module.txt"
)

['attrs>=22.2.0']

4. Preparing metadata

Since all of the necessary information for building a package needs to be contained within main component .py file, basic metadata is provided with the use of __package_metadata__ dictionary object, defined within that .py file. It is also used as a trigger for package building within paa pipeline.

Even though some general information shared between packages could be provided through general config, but package specific info should be provided through __package_metadata__. It should support most text fields from setup file, but for others the following fields are available:

• classifiers: adds classifiers to the general ones from config, unless it's Development Status :: then module level definition will overwrite the one from config
• extras_require: a dictionary of optional package that wouldn't be installed during normal installation. The key could be used during installation and the value would be a list of dependencies.
• install_requires : adds requirements to the list read from imports

* Note that providing dependencies this way does not check them through pip-audit or translate them through package mapping

Initializing MetadataHandler

mh = MetadataHandler(
    # optional/required later
    module_filepath = "../tests/package_auto_assembler/other/example_module.py"
)

Check if metadata is available

mh.is_metadata_available(
    # optional
    module_filepath = "../tests/package_auto_assembler/other/example_module.py"
)

True

Extract metadata from module

mh.get_package_metadata(
    # optional
    module_filepath = "../tests/package_auto_assembler/other/example_module.py"
)

{'author': 'Kyrylo Mordan',
 'author_email': '[e-mail]',
 'version': '0.0.1',
 'description': 'A mock handler for simulating a vector database.',
 'keywords': ['python', 'vector database', 'similarity search']}

5. Merging local dependacies into single module

Package auto assembler creates single module packages, meaning that once package is built all of the object are imported from a single place. The packaging tool does allow for local dependecies which are .py files imported from specified dependencies directory and its subfolders. Packaging structure may look like the following:

packaging repo/
└src/
  ├ <package names>.py
  └ components
    ├local_dependecy.py
    └subdir_1
      └local_dependency_2.py 

During packaging process paa merges main module with its local dependies into a single file.

Initializing LocalDependaciesHandler

ldh = LocalDependaciesHandler(
    # required
    main_module_filepath = "../tests/package_auto_assembler/other/example_module.py",
    dependencies_dir = "../tests/package_auto_assembler/dependancies/",
    # optional
    save_filepath = "./combined_example_module.py"
)

Combine main module with dependacies

print(ldh.combine_modules(
    # optional
    main_module_filepath = "../tests/package_auto_assembler/other/example_module.py",
    dependencies_dir = "../tests/package_auto_assembler/dependancies/",
    add_empty_design_choices = False
)[0:1000])

Save combined module

ldh.save_combined_modules(
    # optional
    combined_module = ldh.combine_modules(),
    save_filepath = "./combined_example_module.py"
)

6. Prepare README

Package description is based on .ipynb with same name as the .py. By default it is converted to markdown as is, but there is also an option to execute it.

import logging
ldh = LongDocHandler(
    # optional/required later
    notebook_path = "../tests/package_auto_assembler/other/example_module.ipynb",
    markdown_filepath = "../example_module.md",
    timeout = 600,
    kernel_name = 'python3',
    # logger
    loggerLvl = logging.DEBUG
)

Convert notebook to md without executing

ldh.convert_notebook_to_md(
    # optional
    notebook_path = "../tests/package_auto_assembler/other/example_module.ipynb",
    output_path = "../example_module.md"
)

Converted ../tests/package_auto_assembler/example_module.ipynb to ../example_module.md

Convert notebook to md with executing

ldh.convert_and_execute_notebook_to_md(
    # optional
    notebook_path = "../tests/package_auto_assembler/other/example_module.ipynb",
    output_path = "../example_module.md",
    timeout = 600,
    kernel_name = 'python3'
)

Converted and executed ../tests/package_auto_assembler/example_module.ipynb to ../example_module.md

Return long description

long_description = ldh.return_long_description(
    # optional
    markdown_filepath = "../example_module.md"
)

7. Assembling setup directory

Packages are created following rather simple sequence of steps. At some point of the process a temporary directory is created to store the following files:

• __init__.py is a simple import from a single module
• <package name>.py is a single module with all of the local dependecies
• cli.py is optional packaged cli tool
• routes.py is optional packaged file with fastapi routes
• streamlit.py is optional packaged streamlit app
• setup.py is a setup file for making a package
• README.md is a package description file based on .ipynb file
• LICENSE is optional license file
• MANIFEST.in is a list of additional files to be included with the package
• mkdocs is a folder with built mkdocs site based on optional extra_docs for the module, module docstring and README.md
• artifacts contains optional files that would be packaged with the module
• tests contains files needed to run tests with pytest
• .paa.tracking contains tracking files from .paa dir to make each release of the package independent of PPR that released it

Initializing SetupDirHandler

sdh = SetupDirHandler(
    # required
    module_filepath = "../tests/package_auto_assembler/other/example_module.py",
    # optional/ required
    module_name = "example_module",
    metadata = {'author': 'Kyrylo Mordan',
                'version': '0.0.1',
                'description': 'Example module.',
                'long_description' : long_description,
                'keywords': ['python']},
    license_path = "../LICENSE",
    requirements = ['attrs>=22.2.0'],
    classifiers = ['Development Status :: 3 - Alpha',
                   'Intended Audience :: Developers',
                   'Intended Audience :: Science/Research',
                   'Programming Language :: Python :: 3',
                   'Programming Language :: Python :: 3.9',
                   'Programming Language :: Python :: 3.10',
                   'Programming Language :: Python :: 3.11',
                   'License :: OSI Approved :: MIT License',
                   'Topic :: Scientific/Engineering'],
    setup_directory = "./example_setup_dir"
)

Create empty setup dir

sdh.flush_n_make_setup_dir(
    # optional
    setup_directory = "./example_setup_dir"
)

Copy module to setup dir

sdh.copy_module_to_setup_dir(
    # optional

sdh.copy_module_to_setup_dir(
    # optional
    license_path = "../LICENSE",
    setup_directory = "./example_setup_dir"
)

Create init file

sdh.create_init_file(
    # optional
    module_name = "example_module",
    setup_directory = "./example_setup_dir"
)

Create setup file

sdh.write_setup_file(
    # optional
    module_name = "example_module",
    metadata = {'author': 'Kyrylo Mordan',
                'version': '0.0.1',
                'description': 'Example Module',
                'keywords': ['python']},
    requirements = ['attrs>=22.2.0'],
    classifiers = ['Development Status :: 3 - Alpha',
                   'Intended Audience :: Developers',
                   'Intended Audience :: Science/Research',

                   'Topic :: Scientific/Engineering'],
    setup_directory = "./example_setup_dir"
)

8. Creating release notes from commit messages

Package versioning could be enhanced with release notes. Since the tool is mainly meant for ci/cd, it takes advantage of commit messages to construct a release note for every version.

Commit history is analysed from the last merge, if nothiong found then the next and the next, until at least one of [<package name>] labels are found within commit messages. They are bundled together to for a note, where each commit message or messages deliminated with ; are turned in a list element. Previos notes are used to establish which part of commit history to use as a starting point.

Commit messages could also be used to increment version by something other then a default patch.

• [<package name>][..+] increments patch (default behavior)
• [<package name>][.+.] increments minor
• [<package name>][+..] increments major
• [<package name>][0.1.2] forces specific version 0.1.2

* First release within new packaging repo may struggle to extract release note since commit messages are only analysed from merges in the commit history.

rnh = ReleaseNotesHandler(
    # path to existing or new release notes file
    filepath = '../tests/package_auto_assembler/other/release_notes.md',
    # name of label in commit message [example_module] for filter
    label_name = 'example_module',
    # new version to be used in release notes
    version = '0.0.1'
)

No relevant commit messages found!

No relevant commit messages found!
No messages to clean were provided

9. Analysing package dependencies

Extracting info from installed dependencies can provide important insight into inner workings of a package and help avoid some of the licenses.

Licenses are extracted from package metadata and normalized for analysis. Missing labels are marked with - and not recognized licenses with unknown.

Information about unrecognized license labels could be provided through .paa/package_licenses json file that would contain install package name and corresponding license label.

da = DependenciesAnalyser(
    # optional
    package_name = 'mocker-db',
    package_licenses_filepath = '../tests/package_auto_assembler/other/package_licenses.json',
    allowed_licenses = ['mit', 'apache-2.0', 'lgpl-3.0', 'bsd-3-clause', 'bsd-2-clause', '-', 'mpl-2.0']
)

Finding installed packages with a list of tags

[('comparisonframe', '0.0.0'),
 ('mocker-db', '0.0.1'),
 ('package-auto-assembler', '0.0.0'),
 ('proompter', '0.0.0')]

Extracting some metadata from the installed package

package_metadata = da.get_package_metadata(
    package_name = 'mocker-db'
)

 "sentence-transformers ; extra == 'sentence_transformers'"]

Extracting tree of dependencies

extracted_dependencies_tree = da.extract_dependencies_tree(
    package_name = 'mocker-db'
)
extracted_dependencies_tree

{'requests': {'charset-normalizer': [],

10. Adding cli interfaces

The tool allows to make a package with optional cli interfaces. These could be sometimes preferable when a package contains a standalone tool that would be called from script anyway.

All of the cli logic would need to be included within a .py file which should be stored within cli_dir provided in .paa.config. Dependencies from these files are extracted in the similar manner to the main module.

Tools from main .py file could still be imported like the following:

from package_name.package_name import ToBeImported

The code is wired in setup.py via the following automatically assuming that appropriate file with the same name as the package exists within cli_dir location.

...,
entry_points = {'console_scripts': [
    '<package_alias> = package_name.cli:cli']} ,
...

Alias for name could be provided via the following piece of code, defined after imports, otherwise package name would be used.

__cli_metadata__ = {
    "name" : <package_alias>
}

Package-auto-assembler tool itself uses click dependency to build that file, use its cli definition as example.

11. Adding routes and running FastAPI application

The tool allows to make a package with optional routes for FastAPI application and run them. Each packages can have one routes file where its logic should be defined. Package-auto-assembler itself can combine multiple routes from packages and filepaths into one application.

A .py file with the same name of the package should be stored within api_routes_dir provided in .paa.config.

Dependencies from these files are extracted in the similar manner to the main module.

Tools from main .py file could still be imported like the following:

from package_name.package_name import ToBeImported

Api description, middleware and run parameters could be provided via optional .paa.api.config file, which for example would look like:

DESCRIPTION : {
    'version' : 0.0.0
}
MIDDLEWARE : {
    allow_origins : ['*']
}
RUN : {
 host : 0.0.0.0
}

where DESCRIPTION contains parameters for FastAPI, MIDDLEWARE for CORSMiddleware and RUN for uvicorn.run

12. Adding ui and running streamlit application

The tools allows to make a package with optional streamlit application as interface to the packaged code. Each package can have one streamlit file. Package-auto-assembler itself would then be used to run packaged applications from the package.

A .py file with the same name of the package should be stored within streamlit_dir provided in .paa.config.

Dependencies from these files are extracted in the similar manner to the main module.

Tools from main .py file could still be imported like the following:

from package_name.package_name import ToBeImported

Config file with server, theme and other settings can be provided via optional .paa.streamlit.config.

13 Adding artifacts to packages

The tool allows to add files to packages that could be accessed from the package or extracted into selected directory.

There are different types of artifacts with a package like this:

• .paa.tracking : includes some tracking files for the purposes of the tool, added to every package
• mkdocs : optional static mkdocs site
• artifacts contains directories, files and links to files

Tracking files are added automatically of artifacts adding was not turned off. At the moment contains:

• .paa.config : config file that specifies how paa show work
• .paa.version: version of package-auto-assembler that was used for packaging
• release_notes.md : latest release notes for the package
• version_logs.csv : logs for version updates for all packages in the packaging repo
• lsts_package_versions.yml : latests versions of all packages in the packaging repo
• package_mapping.json : additional user-provided remapping of package import names to install names
• package_licenses.json : additional user-provided license labels to overwrite detected ones
• notebook.ipynb : optional jupyter notebook that was used for package description

User provided artifacts could be provided in two ways:

• adding directory, file or link to the file under artifacts/<package_name>

These files would be packaged with the packages, and files from links would be downloaded and packaged as well.

• adding artifact_urls dictionary to __package_metadata__ within module .py file

Example of __package_metadata__ with these additional dictionary would be:

__package_metadata__ = {
    "author": "Kyrylo Mordan",
    "author_email": "[e-mail]",
    "description": "A tool to automate package creation within ci based on just .py and optionally .ipynb file.",
    "keywords" : ['python', 'packaging'],
    'license' : 'mit',
    "url" : 'https://kiril-mordan.github.io/reusables/package_auto_assembler/',
    "artifact_urls" : {
        'downloaded.md' : 'https://raw.githubusercontent.com/Kiril-Mordan/reusables/refs/heads/main/docs/module_from_raw_file.md',
        'downloaded.png' : 'https://raw.githubusercontent.com/Kiril-Mordan/reusables/refs/heads/main/docs/reuse_logo.png'
    }
}

where key would contain name of the artifact and value its link.

These files would not be downloaded and only links would be packaged. After package installation both kinds of links could be refreshed/donwloaded using cli interface from package-auto-assembler.

14. Making a package

Main wrapper for the package integrates described above components into a class that could be used to build package building pipelines within python scripts.

To simplify usage cli interface is recomended instead.

15. Making simple MkDocs site

Package documentation can be presented in a form of mkdocs static site, which could be either served or deployed to something like github packages.

Main module docstring is used as intro package that contains something like optional pypi and license badges. Package description and realease notes are turned into separate tabs. Png with diagrams for example could be provided and displayed as their own separate tabs as well.

The one for this package can be seen here

It can be packaged with the package and be displayed in webrowser like documentation for api via {package_name}\docs when using included api handling capabilities.

- preparing inputs

package_name = "example_module"

module_content = LongDocHandler().read_module_content(filepath=f"../tests/package_auto_assembler/{package_name}.py")

docstring = LongDocHandler().extract_module_docstring(module_content=module_content)
pypi_link = LongDocHandler().get_pypi_badge(module_name=package_name)


docs_file_paths = {
    "../example_module.md" : "usage-examples.md",
    '../tests/package_auto_assembler/release_notes.md' : 'release_notes.md'
}

mdh = MkDocsHandler(
    # required
    ## name of the package to be displayed
    package_name = package_name,

    docs_file_paths = docs_file_paths,
    # optional
    ## module docstring to be displayed in the index
    module_docstring = docstring,
    ## pypi badge to be displayed in the index
