What it is

Pronto is a Ruby gem that runs automated code analysis on only the changed lines in a git diff, not the entire codebase. It integrates with GitHub, GitLab, and Bitbucket pull requests to provide quick code review feedback using pluggable linter runners (like pronto-rubocop, pronto-flay, pronto-brakeman). The core capability is fast, targeted code quality checking that reports violations directly to pull request comments. Pronto is a monolithic Ruby gem with two main layers: lib/pronto/runner.rb and lib/pronto/runners.rb orchestrate plugin execution, while lib/pronto/formatter/ (15+ formatter classes) handle output to different VCS platforms (GitHub, GitLab, Bitbucket, text, JSON,…

Start here

Open these first:

• lib/pronto.rb — Main entry point that coordinates the core architecture and loads all submodules for code review analysis.
• lib/pronto/runner.rb — Central orchestrator that executes code review runners against git patches and aggregates findings.
• lib/pronto/cli.rb — Command-line interface that parses arguments and triggers the review workflow for different platforms.
• lib/pronto/git/patches.rb — Extracts and represents git diffs as analyzable patches, the core data structure for targeted reviews.
• lib/pronto/message.rb — Standardized review finding representation that all formatters and backends consume.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone the repository, verify the Gemfile for dependencies (not shown in provided data), then install: gem install pronto or add to Gemfile and run bundle install. The README shows no complex setup beyond installing…

Daily commands:

Primary usage: pronto run (diffs HEAD against master), pronto run --staged (analyzes git staging area), pronto run --unstaged (uncommitted changes), pronto run -c=<commit> (diffs HEAD against specified commit).…

…shortened for this brief.

Key cautions & unknowns

• Scorecard: marked unmaintained (0/10)
• Key gotchas: (1) Default branch assumption — pronto defaults to comparing against 'master', but many repos now use 'main'; the README explicitly warns to use -c=<branch> or set default_commit if your default is not…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
