FOSSLight Scanner

Analyze at once for Open Source Compliance.

FOSSLight Scanner performs open source analysis after downloading the source by passing a link that can be cloned by wget or git. Instead, open source analysis can be performed for the local source path. The output result is generated in FOSSLight Report format.

• FOSSLight Prechecker Check whether the source code's copyright and license writing rules are complied with.
• FOSSLight Source Scanner Extract license and copyright in the source code using ScanCode.
• FOSSLight Dependency Scanner Extract dependency and OSS information from the package manager's manifest file.
• FOSSLight Binary Scanner Find binary and print OSS information.

        source                  Run FOSSLight Source
        dependency              Run FOSSLight Dependency
        binary                  Run FOSSLight Binary
        prechecker              Run FOSSLight Prechecker
        compare                 Compare two FOSSLight reports

Options:

        -h                      Print help message
        -p <path>               Path to analyze (ex, -p {input_path})
                                 * Compare mode input file: Two FOSSLight reports (supports excel, yaml)
                                   (ex, -p {before_name}.xlsx {after_name}.xlsx)
        -w <link>               Link to be analyzed can be downloaded by wget or git clone
        -f <format>             FOSSLight Report file format (excel, yaml)
                                 * Compare mode result file: supports excel, json, yaml, html
        -o <output>             Output directory or file
        -c <number>             Number of processes to analyze source
        -e <path>               Path to exclude from analysis (ex, -e {dir} {file})
        -r                      Keep raw data
        -t                      Hide the progress bar
        -v                      Print FOSSLight Scanner version
        -s <path>               Path to apply setting from json file (check format with 'setting.json' in this repository)
                                 * Direct cli flags have higher priority than setting file
                                   (ex, '-f yaml -s setting.json' - result file extension is .yaml)

• Refs.
  • Additional arguments for running dependency analysis. See the FOSSLight Dependency Guide for instructions.
  • In the case of DB URL, it is the DB connection information to be used in FOSSLight Binary.

Ex 1. Local Source Analysis

$ fosslight all -p /home/source_path -d "-a 'source /test/Projects/venv/bin/activate' -d 'deactivate'"

Ex 2. Local Source Analysis with Path to Exclude

$ fosslight all -p /home/source_path -e temp_dir src/temp.py

Ex 3. Download Link and analyze

$ fosslight all -o test_result_wget -w "https://github.com/LGE-OSS/example.git"

If you want to analyze private repository, set your github token like below.

$ fosslight all -w "https://[e-mail]/Foo/private_repo

Ex 4. Compare the BOM of two FOSSLight reports with yaml or excel format and check the oss status (change/add/delete)

$ fosslight compare -p FOSSLight_before_proj.yaml FOSSLight_after_proj.yaml -f excel
