Cross Package Manager

Introduction

CrossPM (Cross Package Manager) is a universal extensible package manager. It lets you download and as a next step - manage packages of different types from different repositories.

Out-of-the-box modules:

• Adapters

  • Artifactory

• Package file formats

  • zip

  • tar.gz

  • nupkg (treats like simple zip archive for now)

Modules planned to implement:

• Adapters

  • filesystem

  • git

  • smb

  • sftp/ftp

• Package file formats

  • nupkg (nupkg dependencies support)

  • 7z

We also need your feedback to let us know which repositories and package formats do you need, so we could plan its implementation.

The biggest feature of CrossPM is flexibility. It is fully customizable, i.e. repository structure, package formats, packages version templates, etc.

To handle all the power it have, you need to write configuration file (crosspm.yaml) and manifest file with the list of packages you need to download.

Configuration file format is YAML, as you could see from its filename, so you free to use yaml hints and tricks, as long, as main configuration parameters remains on their levels :)

Documentation

We just started to write documentation for this project, but we’ll try to cover all usage topics ASAP.

Here is direct link to it: https://crosspm.readthedocs.io

Installation

To install CrossPM, simply:

pip install crosspm

Usage

To see commandline parameters help, run:

crosspm --help

You’ll see something like this:

CrossPM (Cross Package Manager) version: *** The MIT License (MIT)

    --output=FILE                   Output file name (required if --out_format is not stdout)
    --out-prefix=PREFIX             Prefix for output variable name [default: ] (no prefix at all)
    --no-fails                      Ignore fails config if possible.

Full description for each parameter will be added here some day before NY 2017 :)

We’ll add some more examples soon. Here is one of configuration file examples for now:

Config file description:

Let’s keep in mind that any value we use in path, properties and columns description, called column in CrossPM.

import	If defined, imports yaml config parts from other files. Must be the first parameter in config file.
cpm	Main configuration such as manifest file name and cache path. description Short description of your configuration file. dependencies Manifest file name (not path - just filename) dependencies-lock Manifest with locked dependencies (without masks and conditions) file name (not path - just filename). Equals to dependencies if not set. cache Path for CrossPM temporary files, downloaded package archives and unpacked packages. Ignored if cache folder is configured in top cache item.
cache	Parameters for cache handling. cmdline Command line option name with path to cache folder. env Environment variable name with path to cache folder. Used if command line option is not set. default Default path to cache folder. Used if command line option and environment variable are not set. path Path to cache folder. cmdline, env and default are ignored if path set. clear Parameters for cleaning cache. days Delete files or folders older than days. size Delete older files and folders if cache size is bigger than size. Could be in b, Kb, Mb, Gb. Bytes (b) is a default. auto Call cache check and clear before download.
columns	Manifest file columns definition. Asterisk here points to name column (column of manifest file with package name). CrossPM uses it for building list with unique packages (i.e. by package name)
values	Lists or dicts of available values for some columns (if we need it).
options	Here we can define commandline options and environment variable names from which we will get some of columns values. We can define default values for those columns here too. Each option must be configured with this parameters: cmdline Command line option name with option’s value. env Environment variable name with option’s value. Used if command line option is not set. default Default option’s value. Used if command line option and environment variable are not set.
parsers	Rules for parsing columns, paths, properties, etc. columns Dictionary with column name as a key and template as a value. Example: version: "{int}.{int}.{int}[.{int}][-{str}]" means that version column contains three numeric parts divided by a dot, followed by numeric or string or numeric and string parts with dividers or nothing at all. sort List of column names in sorting order. Used for sorting packages if more than one version found for defined parameters. Asterisk can be one of values of a list representing all columns not mentioned here. index Used for picking one element from sorted list. It’s just a list index as in python. path Path template for searching packages in repository. Here {} is column, [|] is variation. Example: path: "{server}/{repo}/{package}/{compiler|any}/{osname}/{package}.{version}[.zip|.tar.gz]" these paths will be searched: https://repo.some.org/artifactory/libs-release.snapshot/boost/gcc4/linux/boost.1.60.204.zip https://repo.some.org/artifactory/libs-release.snapshot/boost/gcc4/linux/boost.1.60.204.tar.gz https://repo.some.org/artifactory/libs-release.snapshot/boost/any/linux/boost.1.60.204.zip https://repo.some.org/artifactory/libs-release.snapshot/boost/any/linux/boost.1.60.204.tar.gz properties Extra properties. i.e. object properties in Artifactory
defaults	Default values for columns not defined in options.
solid	Set of rules pointing to packages which doesn’t need to be unpacked. ext File name extension (i.e. “.tgz”, “.tar.gz”, or more real example “.deb”)
fails	Here we can define some rules for failing CrossPM jobs. unique List of columns for generating unique index.
common	Common parameters for all or several of sources.
sources	Sources definition. Here we define parameters for repositories access. type Source type. Available types list depends on existing adapter modules. parser Available parsers defined in parsers. server Root URL of repository server. repo Subpath to specific part of repository on server. auth_type Authorization type. For example simple. auth Authorization data. For simple here we define login and password.
output	Report output format definition. tree columns and widths for tree output, printed in the end of CrossPM job.
