if ci_badges.map(&:color).detect { it != "green"} ☝️ let me know, as I may have missed the discord notification.

if ci_badges.map(&:color).all? { it == "green"} 👇️ send money so I can do more of this. FLOSS maintenance is now my full-time job.

Binary::Merge provides shared binary-family report helpers. It does not pretend arbitrary bytes are structurally mergeable; instead, it records byte ranges, render policies, preservation decisions, and unsafe mutation diagnostics for callers that understand a binary schema.

• Binary feature profile for fixture runners.
• Render policy helpers for schema-aware binary renderers.
• Unsafe mutation diagnostics with byte ranges.
• Preservation reports for callers that can safely retain raw byte ranges.

Compatible with MRI Ruby 4.0.0+, and concordant releases of JRuby, and TruffleRuby. CI workflows and Appraisals are generated for MRI Ruby 4.0.0+. This test floor is configured by ruby.test_minimum in .kettle-jem.yml and may be higher than the gem's runtime compatibility floor when legacy Rubies are not practical for the current toolchain.

The amazing test matrix is powered by the kettle-dev stack.

Install the gem and add to the application's Gemfile by executing:

bundle add binary-merge

If bundler is not being used to manage dependencies, install the gem by executing:

gem install binary-merge

Binary::Merge has no global parser configuration. Callers pass schema paths, byte ranges, operations, dispositions, and reasons into the helper methods they need.

Use this package as a substrate for schema-specific binary families such as zip-merge.

require "binary/merge"

report = Binary::Merge.preservation_report(
  format: "custom-binary",
  schema: "custom.ksy",
  matched_schema_paths: ["/header"],
  preserved_ranges: [TreeHaver::ByteRange.new(start_byte: 0, end_byte: 16)],
)

puts report.format

See SECURITY.md.

If you need some ideas of where to help, you could work on adding more code coverage, or if it is already 💯 (see below) check issues or PRs, or use the gem and think about how it could be better.

We so if you make changes, remember to update it.

See CONTRIBUTING.md for more detailed instructions.

This library follows for its public API where practical. For most applications, prefer the Pessimistic Version Constraint with two digits of precision.

For example:

spec.add_dependency("binary-merge", "~> 7.0")

See CHANGELOG.md for a list of releases.
