dpkg facts

class reemote.facts.dpkg.get_packages.Get_packages

Bases: object

Retrieves a list of installed Debian packages.

This operation executes dpkg-query -W on the remote host and parses the output. The result is a structured list of installed packages, which replaces the stdout in the final result object.

Each package is represented as a dictionary with ‘name’ and ‘version’ keys.

Examples:

# In a reemote task function, get a list of all installed packages
packages_result = yield Get_packages()

# The parsed list is in the stdout attribute of the result
print(packages_result.stdout)
# Outputs: [{'name': 'wget', 'version': '1.20.3-1ubuntu1'}, ...]

reemote.facts.dpkg.get_packages.parse_dpkg_list_installed(output)

Parses the raw string output of dpkg-query -W.

This function processes the multiline string returned by the dpkg-query -W command, which lists installed Debian packages. It converts this raw text into a structured list of dictionaries.

Each line of the input is expected to contain the package name followed by its version, separated by whitespace. Lines that are empty or malformed are skipped.

Parameters:

output (str) – The raw standard output from the dpkg-query -W command.

Returns:

A list of dictionaries, where each dictionary

represents an installed package and contains ‘name’ and ‘version’ keys.

Return type:

list[dict]
