The AboutCode tool and ABOUT files provide a simple way to document the (origin and license) and other important or interesting information about third-party software components that you use in your project.
You start by storing ABOUT files (a small text file with field/value pairs) side-by-side with each of the third-party software components you use. Each ABOUT file documents one software component origin and license. For more information on the ABOUT file format, visit http://www.dejacode.org There are many examples of ABOUT files (valid or invalid) in the testdata/ directory of the whole repository.
The current version of AboutCode can read these ABOUT files so that you can collect and validate the inventory of third-party components that you use.
This version of AboutCode follows the ABOUT specification version 1.0.0 at: https://github.com/dejacode/about-code-tool/blob/master/SPEC
AboutCode is released under the Apache 2.0 license. See (of course) the about.ABOUT file for details.
The AboutCode tool requires an installation Python 2.7 on Linux, Mac and Windows. You need to install Python if you do not have one already installed.
On Linux and Mac, Python is typically pre-installed. To verify which version may be pre-installed, open a terminal and type:
python --version python2.7 --version
On Linux, Python2.7 may be available from your distro package manager.
On Windows and Mac if version 2.7 is not installed, you can download the latest Python 2.7.x here https://www.python.org/downloads/ :
- Download the .msi installer for Windows or the .dmg archive for Mac.
- Open and run the installer using all the default options.
- On Windows, make sure you install Python in the default c:\Python27 and not on another drive.
- Download the AboutCode tool from a released version at:
Extract the archive to a directory and open a command prompt or shell in this directory. Then on Linux or Mac run:
And on Windows:
For instance on Linux the whole installation would be like this:
$ wget https://github.com/dejacode/about-code-tool/archive/v2.0.2.zip $ unzip v2.0.2.zip $ cd about-code-tool-2.0.2/ $ source configure
On Windows, the whole installation would be like this:
- Download and extract https://github.com/dejacode/about-code-tool/archive/v2.0.2.zip
- open a command prompt and cd to the directory where the zip extraction directory
- run configure
Later on, if opening a new shell or command prompt on an already installed AboutCode you need to activate this installation.
On Linux or Mac, run this:
On Windows, run this:
Once installed, the AboutCode tool is used from the command line. There are three scripts: about.py, genabout.py and genattrib.py. Once you have installed or activated AboutCode, the scripts are invoked from a shell or command prompt in this way:
$ python about_code_tool/about.py <options ....>
See docs/UsingAboutCodetoDocumentYourSoftwareAssets.pdf for a detailed documentation and tutorial or read on the quick instructions below.
Using the about.py script
The about.py script is used to collect existing ABOUT files, validate that they are correct and collect inventories of the documented components in a CSV file.
Usage: about.py [options] input_path output_path input_path can be a file or directory containing .ABOUT files. output_path is a file with a .csv extension. Options: -h, --help Display help --version Display current version, license notice, and copyright notice --overwrite Overwrites the output file if it exists --verbosity=VERBOSITY Print more or fewer verbose messages while processing ABOUT files 0 - Do not print any warning or error messages, just a total count (default) 1 - Print error messages 2 - Print error and warning messages
$ python about_code_tool/about.py ./thirdparty/ thirdparty_about.csv
In this example, the .ABOUT files in the directory thirdparty/ will be parsed and validated to collect the data they contain. The collected information will be saved to the CSV file named "thirdparty_about.csv".
Using the genabout.py script
The genabout.py script is used to generate new ABOUT files by using a CSV file as an input.
Usage: genabout.py [options] input_path output_path input_path is a CSV file using the same format as the CSV created with about.py output_path is a directory where the new .ABOUT files are generated Options: -h, --help Display help --version Display current version, license notice, and copyright notice --verbosity=VERBOSITY Print more or fewer verbose messages while processing ABOUT files 0 - Do not print any warning or error messages, just a total count (default) 1 - Print error messages 2 - Print error and warning messages --action=ACTION Handle different behaviors if ABOUT files already existed 0 - Do nothing if ABOUT file existed (default) 1 - Overwrites the current ABOUT field value if existed 2 - Keep the current field value and only add the "new" field and field value 3 - Replace the ABOUT file with the current generation --copy_files=COPY_FILES Copy the '*_file' from the project to the generated location Project path - Project path --license_text_location=LICENSE_TEXT_LOCATION Copy the 'license_text_file' from the directory to the generated location License path - License text files path --mapping Use the mapping between columns names in your CSV and the ABOUT field names as defined in the MAPPING.CONFIG mapping configuration file. --extract_license Extract License text and create <license_key>.LICENSE side-by-side with the generated .ABOUT file using data fetched from a DejaCode License Library. The following additional options are required: --api_url - URL to the DejaCode License Library API endpoint --api_username - DejaCode username --api_key - DejaCode API key for this username Example syntax: python about_code_tool/genabout.py --extract_license --api_url='api_url' --api_username='api_username' --api_key='api_key'
$ mkdir tmp $ python about_code_tool/genabout.py thirdparty_code.csv tmp/thirdparty_about
In this example, the tool will use the list in the "thirdparty_code.csv" file and generate .ABOUT files in a directory tmp/thirdparty_about/
Using the genattrib.py script
The genattrib.py script is used to generate a credit and license attribution documentation in HTML from a directory containing .ABOUT files.
Usage: genattrib.py [options] input_path output_path component_list input can be a file or directory. output of rendered template must be a file (e.g. .html). component_list is an optional .csv file with an "about_file" column. It is used to limit the attribution generation to the subset of ABOUT files listed here. Options: -h, --help Display help -v, --version Display current version, license notice, and copyright notice --overwrite Overwrites the output file if it exists --verbosity=VERBOSITY Print more or fewer verbose messages while processing ABOUT files 0 - Do not print any warning or error messages, just a total count (default) 1 - Print error messages 2 - Print error and warning messages --template_location=TEMPLATE_LOCATION Use the custom template for the Attribution Generation --mapping Configure the mapping key from the MAPPING.CONFIG
$ python about_code_tool/genattrib.py tmp/thirdparty_about/ tmp/attribution.html thirdparty_code.csv
In this example, the tool will look at the .ABOUT files listed in the "thirdparty_code.csv" from the /tmp/thirdparty_about/ and then generate the attribution output to /tmp/thirdparty_attribution/attribution.html
(See USAGE for a details explaining of each scripts and options.)
