tools-golang Examples

The examples/ directory contains examples for how to use the various tools-golang sub-packages. Sample commands below should be run from within the example's subdirectory.

1-load/

tvloader, spdx

This example demonstrates loading an SPDX tag-value file from disk into memory, and printing some of its contents to standard output.

Run project: go run example_load.go ../sample-docs/tv/hello.spdx

2-load-save/

tvloader, tvsaver

This example demonstrates loading an SPDX tag-value file from disk into memory, and re-saving it to a different file on disk.

Run project: go run example_load_save.go ../sample-docs/tv/hello.spdx test.spdx

3-build/

builder, tvsaver

This example demonstrates building an 'empty' SPDX document in memory that corresponds to a given directory's contents, including all files with their hashes and the package's verification code, and saving the document to disk.

Run project: go run example_build.go project2 ../../testdata/project2 test.spdx

4-search/

idsearcher, tvsaver

This example demonstrates building an SPDX document for a directory's contents (implicitly using builder); searching through that directory for SPDX short-form IDs; filling those IDs into the document's Package and File license fields; and saving the resulting document to disk.

Run project: go run example_search.go project2 ../../testdata/project2/folder test.spdx

5-report/

reporter, tvloader

This example demonstrates loading an SPDX tag-value file from disk into memory, generating a basic report listing counts of the concluded licenses for its files, and printing the report to standard output.

Run project: go run example_report.go ../sample-docs/tv/hello.spdx

6-licensediff

licensediff, tvloader

This example demonstrates loading two SPDX tag-value files from disk into memory, and generating a diff of the concluded licenses for Files in Packages with matching IDs in each document.

This is generally only useful when run with two SPDX documents that describe licenses for subsequent versions of the same set of files, AND if they have the same identifier in both documents.

Run project: go run example_licensediff.go ../sample-docs/tv/hello.spdx ../sample-docs/tv/hello-modified.spdx

7-rdfloader

rdfloader, spdx

This example demonstrates loading an SPDX rdf file from disk into memory and then printing the corresponding spdx struct for the document.

Run project: go run exampleRDFLoader.go ../sample-docs/rdf/SPDXRdfExample-v2.2.spdx.rdf

8-jsontotv

json, tvsaver

This example demonstrates loading an SPDX json from disk into memory and then re-saving it to a different file on disk in tag-value format.

Run project: go run examplejsontotv.go ../sample-docs/json/SPDXJSONExample-v2.2.spdx.json example.spdx

9-tvtojson

json, tvloader

This example demonstrates loading an SPDX tag-value from disk into memory and then re-saving it to a different file on disk in json format.

Run project: go run exampletvtojson.go ../sample-docs/tv/hello.spdx example.json

10-jsonloader

json

This example demonstrates loading an SPDX json from disk into memory and then logging some of the attributes to the console.

Run project: go run example_json_loader.go ../sample-docs/json/SPDXJSONExample-v2.2.spdx.json

11-yamltotv

yaml tvsaver

This example demonstrates loading an SPDX yaml from disk into memory and then re-saving it to a different file on disk in tag-value format.

Run project: go run exampleyamltotv.go ../sample-docs/yaml/SPDXYAMLExample-2.2.spdx.yaml test.spdx

12-tvtoyaml

yaml tvloader

This example demonstrates loading an SPDX tag-value from disk into memory and then re-saving it to a different file on disk in yaml format.

Run project: go run exampletvtoyaml.go ../sample-docs/tv/hello.spdx example.yaml

13-yamlloader

yaml

This example demonstrates loading an SPDX yaml from disk into memory and then logging some of the attributes to the console.

Run project: go run exampleYAMLLoader.go ../sample-docs/yaml/SPDXYAMLExample-2.2.spdx.yaml
