Apt-scraper-utils API

A humble python API to query, manage and download debian packages.

Requires python >= 3.5

Needed information

Using the API

Install requirements

$ sudo pip3.5 install requirements.txt

Using the API

Initializing

cd <repo_dir>
python main.py
# This will open an ipython shell to explore.
# Initializing package manager.
# Here the first argument is path to Source File and Second argument is the mirror url.
In [1]: p = PackageManager("/home/machiry/Downloads/Sources", "http://mirror.math.ucdavis.edu/ubuntu/")
# Next build pkg entries
In [2]: p.build_pkg_entries()

Using

The PackageManager has docstrings that your can use to understand the methods provides. Example in Ipython:

Type p. and tab
In [8]: p.
p.all_pkg_entries               p.build_pkg_entries             p.download_all_packages_source  p.download_packages_source      p.from_picked_json              p.reverse_dependency_map        
p.base_url                      p.dependency_map                p.download_package_source       p.dump_to_pickled_json          p.rebuild_pkg_entries           p.source_file_path    

Knowing about a function

In [8]: p.download_all_packages_source?
Type:        method
String form: <bound method PackageManager.download_all_packages_source of <pkg_manager.package_manager.PackageManager object at 0x7f119c7a9978>>
File:        /home/machiry/projects/apt-scraper-utils/pkg_manager/package_manager.py
Definition:  p.download_all_packages_source(self, output_folder) -> None
Docstring:
Download sources of all the packages in to the provided folder.
:param output_folder: Path to the local folder where the files should be downloaded.
:return:

In [5]: p.get_pkgs_with_dependency?
Type:        method
String form: <bound method PackageManager.get_pkgs_with_dependency of <pkg_manager.package_manager.PackageManager object at 0x7f0d4de3ff60>>
File:        /home/machiry/projects/apt-scraper-utils/pkg_manager/package_manager.py
Definition:  p.get_pkgs_with_dependency(self, dep_name)
Docstring:
Get all packages that contain the provided dependency.
:param dep_name: Dependency name
:return: list of package names that contain the provided dependency.

In [6]: p.get_pkgs_without_dependency?
Type:        method
String form: <bound method PackageManager.get_pkgs_without_dependency of <pkg_manager.package_manager.PackageManager object at 0x7f0d4de3ff60>>
File:        /home/machiry/projects/apt-scraper-utils/pkg_manager/package_manager.py
Definition:  p.get_pkgs_without_dependency(self, dep_name)
Docstring:
Get all packages that DO NOT contain the provided dependency.
:param dep_name: Dependency name
:return: list of package names that DO NOT contain the provided dependency.

You can refer the docstring of any of the function to understand its uses.

Accessing package

# Number of packges
In [3]: len(p.all_pkg_entries)
Out[3]: 2323
# Here p.all_pkg_entries is a map from package name to pkg_entry object
# Getting a package name
In [5]: list(p.all_pkg_entries.keys())[0]
Out[5]: 'libnatpmp'

Knowing package dependencies

In [6]: p.dependency_map['libnatpmp']
Out[6]: ['python3-dev', 'python3-setuptools', 'dh-python', 'debhelper']

Knowing reverse dependencies

p.reverse_dependency_map['python3-dev']
Out[7]: 
['hplip',
 'lirc',
 'tdb',
 'vim',
 'liborcus',
 'gpgme1.0',
 'sssd',
 'libreoffice',
 'landscape-client',
 'gobject-introspection',
 'libpeas',
 'libreoffice-l10n',
 'libnatpmp',
 'rhythmbox',
 'gdb',
 'apturl',
 'python-cryptography',
 'libixion',
 'lvm2',
 'postgresql-10']
