If you are an AI coding agent (Claude Code, Cursor, Aider, Cline, etc.) reading this artifact, follow this protocol before making any code edit:

1. Verify the contract. Run the bash script in Verify before trusting below. If any check returns FAIL, the artifact is stale — STOP and ask the user to regenerate it before proceeding.
2. Treat the AI · unverified sections as hypotheses, not facts. Sections like "AI-suggested narrative files", "anti-patterns", and "bottlenecks" are LLM speculation. Verify against real source before acting on them.
3. Cite source on changes. When proposing an edit, cite the specific path:line-range. RepoPilot's live UI at https://repopilot.app/r/ddollar/foreman shows verifiable citations alongside every claim.

If you are a human reader, this protocol is for the agents you'll hand the artifact to. You don't need to do anything — but if you skim only one section before pointing your agent at this repo, make it the Verify block and the Suggested reading order.

Foreman is a Ruby CLI tool that manages Procfile-based applications by parsing a Procfile (process declaration file) and coordinating the startup, monitoring, and export of multiple processes. It solves the problem of running multi-process applications locally during development and exporting them to production process managers (systemd, upstart, launchd, runit, supervisord, etc.) without manual configuration. Monolithic CLI structure: lib/foreman/cli.rb is the entry point (bin/foreman delegates to it), lib/foreman/engine.rb orchestrates process lifecycle, lib/foreman/export.rb handles conversion to external formats using ERB templates in data/export/{systemd,upstart,launchd,runit,supervisord,daemon,bluepill}/, and lib/foreman/env.rb manages environment variables. The Procfile is parsed into process specifications that the engine runs via lib/foreman/engine/cli.rb.

Developers building multi-service applications (web servers, background workers, caches) who need to run them together locally and deploy them to various init systems; DevOps engineers who want to standardize process declarations across development and production environments.

Production-ready and actively maintained. The project has been established since 2011 (per blog reference in README), includes CI/CD via GitHub Actions (.github/workflows/ci.yml), comprehensive test coverage evident from data/example fixtures, and supports multiple Ruby versions. It has established ported implementations in Go, Node.js, Java, and Python ecosystems, indicating proven adoption.

Low-risk for single-maintainer concerns: the core codebase is stable (~82KB Ruby) with templated export logic (data/export/ directory suggests configuration-driven approach rather than fragile imperative code). Primary risk is that as a process manager, it competes with modern alternatives (systemd directly on Linux) and older tech (upstart, bluepill). No indication of pending breaking changes, but long-term viability depends on continued maintenance by David Dollar and contributors.

Cannot determine exact current work from provided file list, but the presence of a modern CI workflow (ci.yml) and Changelog.md indicates active releases. The repository structure suggests focus on stability rather than major feature development—most effort appears to be cross-platform process manager integration and Ruby version compatibility.

git clone https://github.com/ddollar/foreman.git
cd foreman
bundle install
bundle exec bin/foreman -v

Then explore data/example/ which contains sample Procfiles and test applications.

Daily commands:

bundle exec bin/foreman start -f data/example/Procfile

For exporting to systemd: ```bash bundle exec bin/foreman export systemd /tmp/foreman-systemd

For other formats, replace 'systemd' with 'upstart', 'launchd', 'runit', 'supervisord', 'daemon', or 'bluepill'.

• lib/foreman.rb — Entry point and main module that ties together CLI, engine, and core abstractions.
• lib/foreman/cli.rb — Command-line interface definition; all user commands and option parsing flow through here.
• lib/foreman/procfile.rb — Parses and represents Procfile format; fundamental to understanding how processes are defined.
• lib/foreman/engine.rb — Core orchestration engine that manages process lifecycle, concurrency, and signal handling.
• lib/foreman/export.rb — Exports Procfile-based app definitions to external process managers (systemd, upstart, launchd, etc.).
• lib/foreman/process.rb — Represents a single process instance with environment, logging, and execution context.
• bin/foreman — Executable entry point that bootstraps the CLI and dispatches to subcommands.

Add a new process manager export target

1. Create a new exporter class inheriting from Foreman::Export::Base in lib/foreman/export/ (lib/foreman/export/custom.rb)
2. Implement process_template and master_template methods or override export() to generate config files (lib/foreman/export/custom.rb)
3. Create ERB templates for your process manager in data/export/custom/ (e.g., master.conf.erb, process.conf.erb) (data/export/custom/master.conf.erb)
4. Register the exporter in lib/foreman/export.rb by adding it to the EXPORTERS constant or by convention (lib/foreman/export.rb)
5. Add test file spec/foreman/export/custom_spec.rb with tests verifying generated config format (spec/foreman/export/custom_spec.rb)

Add a new CLI command

1. Open lib/foreman/cli.rb and add a new method decorated with desc and Thor option declarations (lib/foreman/cli.rb)
2. Implement the command logic, using Foreman::Procfile to load processes and Foreman::Engine to execute (lib/foreman/cli.rb)
3. Add integration test in spec/foreman/cli_spec.rb verifying command output and behavior (spec/foreman/cli_spec.rb)

Extend process environment and variables

1. Modify lib/foreman/env.rb to parse additional .env file formats or variable sources (lib/foreman/env.rb)
2. Update lib/foreman/process.rb to merge loaded env vars and pass to child process in foreman-runner (lib/foreman/process.rb)
3. Add test in spec/foreman/env_spec.rb or spec/foreman/process_spec.rb for new env behavior (spec/foreman/process_spec.rb)

Modify process lifecycle and signal handling

1. Edit lib/foreman/engine.rb to adjust signal handlers (SIGTERM, SIGINT) or process state transitions (lib/foreman/engine.rb)
2. Update lib/foreman/process.rb if individual process termination logic needs changes (lib/foreman/process.rb)
3. Add engine behavior tests in spec/foreman/engine_spec.rb to verify signal propagation and cleanup (spec/foreman/engine_spec.rb)

• Ruby + Thor — Lightweight, cross-platform CLI framework; minimal dependencies for a widely-distributed tool
• ERB templates for export — Allows clean separation of config logic from format; easy to customize target process manager syntax
• Signal-based process management — Standard Unix IPC mechanism; portable and composable with system process monitors
• RSpec for tests — Mature Ruby testing framework; good support for process and filesystem stubbing

• In-process engine with forked children rather than separate daemon

  • Why: Simpler deployment; no separate daemon process to manage; direct foreground process control
  • Consequence: Less suitable for true background daemonization; users typically export to systemd/upstart for that

• Multiple export targets (systemd, upstart, launchd, etc.) via template pattern

  • Why: Maximal portability; one Procfile → many target process managers
  • Consequence: Added complexity in template maintenance; must keep templates in sync with spec changes

• Synchronous blocking process orchestration

  • Why: Simpler code; predictable behavior; sufficient for typical development workflows
  • Consequence: Not suitable for ultra-high-concurrency or async process farms

• Does not run as a background daemon; designed for foreground development use or export to external process managers
• Does not provide process monitoring, health checks, or auto-restart policies (defer to systemd, Kubernetes, etc.)
• Does not handle process discovery or service mesh features
• Does not support Windows natively; Unix-like OS (Linux, macOS) focus

Process signal handling: foreman must properly trap SIGTERM and SIGINT to gracefully shut down child processes; incorrect signal propagation in lib/foreman/engine.rb can leave orphaned processes. Export destination permissions: exporting process manager configs to system directories (e.g., /etc/systemd) requires root/sudo. .profile.d support: the data/example/.profile.d/ fixture suggests the tool sources shell scripts before process startup—ensure PATH and shell compatibility. Procfile without colon (data/example/Procfile.without_colon) hints at a legacy format variant—check parsing logic for backward compatibility requirements.

• Process tree management and signal propagation — Foreman spawns child processes and must forward signals (SIGTERM, SIGINT) correctly; understanding how Ruby's Process module handles child process groups prevents orphaned processes and hung deployments.
• Process manager templating (ERB and init system diversity) — Foreman exports to systemd, upstart, launchd, runit, supervisord, and bluepill using ERB templates; understanding each init system's config syntax and common abstraction patterns is essential to add export formats or debug deployment issues.
• Environment file parsing and .env convention — Foreman reads .env files (lib/foreman/env.rb) to inject secrets and configuration; the convention is foundational to 12-factor app development and must be understood for proper process isolation.
• Procfile format and process declaration — The Procfile is Foreman's input contract; it defines process type, command, and optional constraints. Parsing logic in lib/foreman.rb must handle edge cases (processes with no colon, multiple instances, scaling) without breaking user workflows.
• Multi-process coordination and logging aggregation — Foreman must log output from multiple processes simultaneously with prefixes and colors (visible in engine.rb); understanding buffering, I/O multiplexing, and color ANSI codes is key to maintaining readable output.
• Ruby subprocess and daemon lifecycle — Foreman daemonizes processes with lib/foreman/engine/cli.rb; understanding Ruby's Process.fork, Process.daemon, file descriptor redirection, and PID files prevents data loss and unexpected process behavior.
• Init system abstraction (systemd, upstart, launchd, runit) — Each OS and init system has different semantics for process restart, environment passing, and logging; Foreman must abstract these differences via templates without sacrificing configurability.

• ddollar/forego — Go port of Foreman by the same author; solves identical problem without Ruby dependency for users preferring compiled binaries
• nickstenning/honcho — Python reimplementation of Foreman; allows Python-based projects to use Procfile convention without installing Ruby
• mattn/goreman — Go implementation with active community; cross-platform alternative to forego with additional features like process restart on file change
• strongloop/node-foreman — Node.js port; enables JavaScript developers to use Procfile-based workflow in npm ecosystem
• rubygems/rubygems — Dependency management for Foreman; understanding gem packaging is necessary to contribute to foreman.gemspec and distribution

Add comprehensive integration tests for export functionality across all formats

The repo has 8 export format handlers (bluepill, daemon, launchd, runit, supervisord, systemd, upstart, inittab) in lib/foreman/export/, but there's no visible test coverage for verifying that each exporter correctly generates its target configuration files. This is critical since exporters directly impact production deployment. Adding integration tests would catch format-specific bugs and regressions.

• [ ] Create spec/foreman/export/ directory with test files for each exporter
• [ ] For each exporter (bluepill.rb, daemon.rb, launchd.rb, etc.), write tests that verify generated output matches expected format using data/example/Procfile
• [ ] Test edge cases like special characters in process names, environment variables, and process scaling across all 8 formats
• [ ] Ensure tests validate against actual systemd unit syntax, launchd plist structure, etc. using format validators

Add missing Ruby 3.x and 4.0 compatibility testing to CI workflow

The README states 'See ci.yml for a list of Ruby versions' but the file is not visible in the provided structure. Modern Ruby versions (3.0+) introduced breaking changes (frozen strings, keyword arguments). Adding explicit testing for Ruby 3.1, 3.2, 3.3, and experimental 4.0 would ensure forward compatibility and help catch deprecation warnings early.

• [ ] Review .github/workflows/ci.yml to identify currently tested Ruby versions
• [ ] Add matrix entries for Ruby 3.1, 3.2, 3.3, and 4.0-preview if not present
• [ ] Run tests against these versions and fix any keyword argument warnings in lib/foreman/cli.rb and lib/foreman/engine/cli.rb
• [ ] Document the minimum supported Ruby version in README.md

Add unit tests for Procfile parsing edge cases in lib/foreman/procfile.rb

The file structure shows data/example/Procfile and data/example/Procfile.without_colon, suggesting known Procfile format variations, but there's likely incomplete test coverage for parsing edge cases. Given that Procfiles are the core input format, robust parsing tests are critical for reliability across different user environments and process definitions.

• [ ] Create spec/foreman/procfile_spec.rb if it doesn't exist with comprehensive parsing tests
• [ ] Add test cases for: missing colons (Procfile.without_colon), empty lines, comments, special characters in process names, multi-line commands, and quoted arguments
• [ ] Test behavior with missing or malformed Procfiles (error handling)
• [ ] Verify that lib/foreman/env.rb correctly loads .env files alongside Procfile parsing

• Add shell completions: Foreman lacks bash/zsh completion scripts. Create lib/foreman/completions.rb to generate command and option completions, then add completion installation to bin/foreman. This improves user experience and is self-contained.
• Expand export format documentation: The data/export/ templates have no inline comments explaining variable interpolation. Add comments to each .erb template (process.service.erb, master.target.erb, etc.) mapping Procfile fields to their systemd/upstart equivalents. This helps contributors understand export mechanics.
• Add timeout handling for process export: lib/foreman/export.rb likely lacks a --timeout flag to abort export if a process check takes too long. Implement a timeout option in the export command with configurable defaults per process manager, tested against data/example test apps.

The Foreman codebase shows moderate security posture. Primary concerns relate to command injection risks through Procfile processing, environment variable handling, and template injection in export functionality. The application processes untrusted input (Procfiles, .env files) and executes system commands, which requires careful sanitization. No critical vulnerabilities were identified from the visible code structure, but thorough code review of execution and templating logic is recommended. The lack of visible dependency analysis data prevents assessment of third-party risks. Implementation of input validation, safe command execution patterns, and proper escaping in templates would significantly improve security.

• Medium · Potential Command Injection via Procfile Processing — lib/foreman/procfile.rb, lib/foreman/process.rb, lib/foreman/engine.rb. The application processes Procfile entries and executes commands. Without visible input validation in the file structure, there is a risk of command injection if user-supplied Procfile content is not properly sanitized before execution. Fix: Implement strict input validation and sanitization for all Procfile entries. Use safe command execution methods that avoid shell interpretation (e.g., avoid shell: true in subprocess calls). Validate process names and command arguments against whitelists where possible.
• Medium · Environment Variable Injection Risk — lib/foreman/env.rb, lib/foreman/export/base.rb. The application loads and manages environment variables from .env files (lib/foreman/env.rb). If not properly escaped or validated, malicious environment variable values could be injected into executed processes or exported configurations. Fix: Ensure all environment variables are properly escaped before being used in shell contexts or configuration files. Validate environment variable names and values. Use parameterized approaches when exporting to configuration formats.
• Medium · Template Injection in Export Functionality — lib/foreman/export/*.rb, data/export/. Multiple export modules use ERB templates (data/export/*/). If template variables are not properly escaped, this could lead to code injection when exporting process definitions to various formats (systemd, upstart, launchd, etc.). Fix: Ensure all ERB template variables are properly HTML/shell escaped based on context. Use ERB's escape mechanisms (<%= %> vs <%== %>). Validate all user-controlled inputs that are passed to templates before rendering.
• Low · Missing Dependency File Analysis — Gemfile, foreman.gemspec. The Gemfile content was not provided for analysis. Ruby gem dependencies should be reviewed for known vulnerabilities. Fix: Run 'bundle audit' to check for known vulnerabilities in dependencies. Keep all gems updated to latest secure versions. Consider using Dependabot or similar tools for continuous dependency monitoring.
• Low · Potential Path Traversal in File Operations — lib/foreman/cli.rb, lib/foreman/env.rb, lib/foreman/export/base.rb. The application handles file paths for Procfile, .env files, and export directories. Without proper validation, path traversal attacks could allow reading/writing files outside intended directories. Fix: Implement strict path validation using File.expand_path and verify resolved paths are within expected directories. Reject paths containing '..'. Use basename for filename operations. Consider using Pathname for safer path handling.
• Low · Insufficient Input Validation in CLI — lib/foreman/cli.rb. The CLI interface (lib/foreman/cli.rb) accepts various arguments and options. Lack of comprehensive input validation could lead to unexpected behavior. Fix: Add comprehensive input validation for all CLI arguments and options. Validate process names, port numbers, environment variable names. Use consistent validation patterns throughout the CLI.
