rga is a CLI search tool that wraps ripgrep to search text across 40+ file formats (PDFs, DOCX, EPUB, SQLite, archives like ZIP/TAR/BZ2, images with OCR, video subtitles, email attachments). It recursively descends into nested archives and extracts searchable text using external tools (pandoc, pdftotext, ffmpeg, etc.) before passing results to ripgrep's regex engine. Monolithic Rust binary (Cargo.toml at root, edition 2024) with no separate crate breakdown. Core logic likely in src/ (inferred), adapters for file types handled via trait-based architecture (async-trait 0.1.68, dyn-clonable 0.9.0 suggest polymorphic handler design), external tool calls orchestrated via tokio runtime, results piped to ripgrep subprocess.

Software engineers, data analysts, and researchers who need to grep across document collections and archives without manually unpacking files—people working with mixed-format datasets, archived project files, or document repositories who want ripgrep's speed and regex power without format barriers.

Actively developed and production-ready: version 0.10.10 with established distribution channels (Homebrew, Chocolatey, Scoop, Arch Linux, Gentoo, Nix), comprehensive CI/CD pipelines (.github/workflows/ci.yml and release.yml), and example test directories (exampledir/ with 50+ format samples). Single active maintainer (phiresky) but stable release cadence suggests maturity.

Moderate risk: 40+ external tool dependencies (pandoc, poppler, ffmpeg, sqlite3) create installation complexity and platform-specific fragility—Windows users must use package managers (Chocolatey/Scoop) or manually resolve VCRUNTIME. Heavy async/tokio usage (0.1.28.1 with full feature set) and tree_magic_mini MIME detection add complexity. Single maintainer with no visible co-maintainers increases bus factor risk.

No specific PR/milestone data visible in provided files, but .github/workflows/ci.yml and release.yml indicate active CI/CD. CHANGELOG.md and version 0.10.10 suggest recent maintenance. No breaking changes noted, pointing toward incremental feature additions or stability work.

git clone https://github.com/phiresky/ripgrep-all.git
cd ripgrep-all
cargo build --release
./target/release/rga --help

Then install dependencies: on Linux apt install pandoc poppler-utils ffmpeg, on macOS brew install pandoc poppler ffmpeg, on Windows use choco install ripgrep-all (single-command wrapper).

Daily commands:

cargo run -- 'search_pattern' exampledir/

Or use pre-built binary: rga 'search_pattern' /path/to/files. See README and doc/config.default.jsonc for configuration. Example test data in exampledir/ with nested archives and format samples.

• src/bin/rga.rs — Main entry point for the rga CLI tool; handles command-line argument parsing and orchestrates the search pipeline.
• src/adapters.rs — Core adapter registry and trait definitions; every file format support depends on adapters registered here.
• src/adapters/decompress.rs — Handles decompression of archives (tar, gz, zip, etc.); critical path for nested archive recursion.
• src/preproc.rs — Preprocessing pipeline that routes files to appropriate adapters and manages text extraction workflow.
• src/preproc_cache.rs — Caching layer for preprocessed output to avoid re-extracting the same file multiple times.
• Cargo.toml — Dependency management and feature flags (perf-literal); defines which compression and file format libraries are available.
• src/lib.rs — Library root exposing public API for embedded use; defines module structure and shared types.

• Adapter System (adapters.rs + adapters/*) (Trait objects, async/await, format-specific crates (pdfium, calamine, rusqlite, ffmpeg-next, etc.)) — Detects file format and extracts searchable text; each adapter implements Adapter trait with lines() iterator
  • Failure mode: Unsupported format silently skipped or malformed extraction produces garbage matches; error handling varies by adapter
• Preprocessing Pipeline (preproc.rs) (Async streams, tokio channels, custom iterators) — Routes files through adapters, manages extraction workflow, handles encoding and line normalization
  • Failure mode: Extraction failure stops processing of that file; error logged but search continues on other files
• Recursion Engine (recurse.rs) (Recursive algorithms, DFS traversal, custom file iterators) — Descends into nested archives and filesystem; maintains depth tracking and file enumeration
  • Failure mode: Infinite loop in circular symlinks or pathological nesting; mitigated by depth/size limits
• Caching Layer (preproc_cache.rs, caching_writer.rs) (HashMap-based cache, LRU) — Stores extracted text in memory to avoid redundant extraction on repeated searches

Add Support for a New File Format

1. Create a new adapter file in src/adapters/{format}.rs implementing the Adapter trait with an as_any() method and lines() iterator (src/adapters/{format}.rs)
2. Register the adapter in the get_adapters() function or custom adapter loader in src/adapters.rs (src/adapters.rs)
3. Add format-specific dependencies to Cargo.toml if needed (Cargo.toml)
4. Test with exampledir/ test files and verify output via rga-preproc.rs binary (src/bin/rga-preproc.rs)

Add a New Compression Format

1. Extend the match statement in src/adapters/decompress.rs to detect the new format by extension (src/adapters/decompress.rs)
2. Add async decompression logic using async-compression or equivalent library (src/adapters/decompress.rs)
3. Add test files to exampledir/decompress/ with the new extension (exampledir/decompress/)

Modify Caching Behavior

1. Review cache key generation and TTL logic in src/preproc_cache.rs (src/preproc_cache.rs)
2. Update cache invalidation or expiration rules as needed (src/preproc_cache.rs)
3. Adjust max cache size or invalidation strategy in src/config.rs if user-configurable (src/config.rs)

• Rust + Tokio async — Fearless concurrency for processing multiple large files; async handles I/O-bound decompression and extraction without blocking
• Ripgrep (regex engine) — Battle-tested, fast line-oriented regex matching; rga wraps it rather than reimplementing to leverage existing performance
• async-compression + async_zip — Non-blocking decompression of multiple archive formats; critical for searching large compressed files
• FFmpeg integration — Extracts text from video files (subtitles, metadata) without reimplementing video codec support

• Adapter-based plugin system instead of monolithic format handler

  • Why: Allows independent format support without rebuilding core; each adapter can have different dependencies
  • Consequence: Requires registration boilerplate; adding format support involves creating new file + modifying adapters.rs

• Preprocess and cache extracted text before passing to ripgrep

  • Why: Archives and complex formats require extraction once; caching amortizes cost across repeated searches
  • Consequence: Higher memory usage for large files; added latency on first search but massive speedup on repeated patterns

• Recursive descent into nested archives

  • Why: User expectation: search 'inside everything' including zip-within-tar
  • Consequence: Potential for pathologically nested archives to cause stack depth or performance issues; mitigation via depth limits

• No built-in support for custom adapters in binary (config-based only)

  • Why: Simplifies distribution and security; users don't need to compile custom Rust code
  • Consequence: Limited extensibility for proprietary formats; would require fork or patch

• Real-time indexing or daemon mode (each invocation is stateless search)
• Supporting all possible file formats (scope limited to common document/archive types)
• Providing a graphical user interface (CLI + shell integration via rga-fzf.rs)

External tool dependency version constraints—older pdftotext or ffmpeg versions may produce different output formats, breaking tests (see ci/ubuntu-install-packages and ci/macos-install-packages for pinned versions). Config file location searched in XDG_CONFIG_HOME (via directories-next 2.0.0)—if unset, rga may fail silently. tokio-rusqlite 0.5.0 requires Tokio 1.x runtime, incompatible with sync code. AGPL-3.0-or-later license (LICENSE.md) means any modifications must be open-sourced. Archive nesting depth affects memory usage—very deep TAR-in-ZIP-in-TAR structures may exhaust RAM on older systems.

• Polymorphic file adapters via trait objects (dyn-clonable, async-trait) — rga handles 40+ file types by delegating extraction to trait-based handlers; understanding how Rust's dyn Trait and async-trait enable runtime dispatch of format-specific extractors is key to modifying or extending the adapter system
• Streaming archive extraction (async_zip, tokio-tar, async-compression) — rga recursively descends nested TAR/ZIP/BZ2/XZ/ZSTD archives without unzipping to disk; understanding async streaming prevents memory exhaustion on large archives and is critical for performance tuning
• MIME type detection and file type routing (tree_magic_mini) — rga identifies file formats by magic bytes (not extensions), routing each to the correct adapter; tree_magic_mini's detection logic is central to format support and contributes to robustness against misnamed files
• Subprocess piping and ripgrep integration (tokio process spawning) — rga extracts searchable text to stdout, then pipes it to ripgrep as a subprocess; understanding process lifecycle, stdin/stdout buffering, and exit code handling is crucial for debugging search failures or performance bottlenecks
• External tool dependency resolution and fallback (PATH environment variable wrapping) — rga searches for pandoc, pdftotext, ffmpeg in $PATH and the binary's directory; understanding this resolution strategy explains cross-platform fragility and why package manager installation is required on Windows
• Character encoding detection and transcoding (encoding_rs, encoding_rs_io) — rga handles text in UTF-16, Latin-1, and other charsets (exampledir/encoding/ has samples); encoding_rs prevents mangled search results on non-UTF-8 files and is vital for international document support
• Configuration schema versioning and JSON comments (schemars, json_comments) — rga reads config from doc/config.default.jsonc with comments; schemars generates JSON schema for validation, enabling IDE autocomplete and static config validation—important for users managing large adapter registries

• BurntSushi/ripgrep — The core regex engine that rga wraps; understanding ripgrep's invocation, output format, and flags is essential for debugging search behavior
• ugrep/ugrep — Alternative regex search tool with built-in support for some compressed formats (bz2, xz, gzip), solves overlapping problem without wrapping external tools
• sharkdp/fd — Companion tool from same ecosystem (blazing-fast Rust CLI replacements); rga users often combine fd for file discovery before piping to rga
• junegunn/fzf — Fuzzy finder that integrates with rga via rga-fzf wrapper (mentioned in README wiki); ecosystem integration point for interactive search workflows
• xalanq/cf-tool — Examples of async Rust CLI architecture similar to rga's tokio-based design; useful reference for understanding async file I/O patterns

Add integration tests for archive extraction and nested file searching

The repo has extensive example files in exampledir/ (PDFs, ZIPs, TARs, nested archives like droste.zip, mail with attachments, etc.) but there's no visible test suite validating that these files are correctly extracted and searched. This is critical for a tool that prides itself on handling multiple archive formats. New contributors could create a test suite using the existing exampledir/ fixtures.

• [ ] Create tests/integration_tests.rs or similar
• [ ] Add tests for each archive type in exampledir/ (zip, tar.gz, tar.bz2, tar.xz, etc.)
• [ ] Add tests for nested archives (exampledir/droste.zip)
• [ ] Add tests for mail attachments (exampledir/test/mail_with_attachment.mbox, exampledir/mail_pdf_attach.eml)
• [ ] Add tests for encoding edge cases (exampledir/encoding/utf16le.txt, utf8.txt)
• [ ] Run tests in CI to catch regressions (see .github/workflows/ci.yml)

Add GitHub Actions workflow for testing multiple archive format support

While .github/workflows/ci.yml and release.yml exist, there's no dedicated workflow explicitly testing archive extraction (zip, tar, tar.gz, etc.) and file type detection (tree_magic_mini dependency). Given the core value prop is multi-format support, a dedicated workflow would catch regressions early and demonstrate the tool's capabilities.

• [ ] Review existing .github/workflows/ci.yml to understand current test setup
• [ ] Create .github/workflows/archive-formats.yml that runs on push/PR
• [ ] Add test matrix for different archive formats using exampledir/ files
• [ ] Include tests for file type detection using tree_magic_mini
• [ ] Verify searches work across nested archives and compressed files
• [ ] Document in README or CONTRIBUTING.md how to run tests locally

Document configuration schema with examples for doc/config.default.jsonc

doc/config.default.jsonc exists but has no accompanying documentation explaining each configuration option. The repo uses schemars for JSON schema generation but users have no guide. Create a comprehensive config documentation guide with examples for common use cases.

• [ ] Review Cargo.toml to understand schemars setup and how config schema is generated
• [ ] Create doc/CONFIG.md with detailed explanations for each option in config.default.jsonc
• [ ] Add examples for: custom adapters, archive extraction settings, performance tuning, encoding handling
• [ ] Document how to generate and validate JSON schema (schemars integration)
• [ ] Link doc/CONFIG.md from README.md in relevant section
• [ ] Include troubleshooting section for common config issues (e.g., missing dependencies for PDF extraction)

• Add integration tests for each file type in exampledir/: currently exampledir has demo data (demo/hello.odt, short.pdf, test.zip) but no visible test suite validating extraction + regex matching for each format (DOCX, EPUB, SQLite, DJVU). Start by writing tests in tests/ that call rga on exampledir samples and assert output.
• Document adapter architecture in README or CONTRIBUTING.md: Cargo.toml shows tree_magic_mini MIME detection and async-trait polymorphism, but new contributors can't identify where file type handlers live or how to add one. Map file types (MIME ranges) to adapter module names with code examples.
• Add Windows dependency installer CI step: currently ci/ubuntu-install-packages and ci/macos-install-packages exist but no ci/windows-install-packages, and README warns users to use Chocolatey/Scoop instead of providing direct binary downloads. Create a PowerShell script or batch file that auto-installs pandoc, poppler, ffmpeg, and ripgrep via package managers.

• High · Incomplete Package Manifest — Cargo.toml (dev-dependencies section). The Cargo.toml file contains an incomplete dev-dependency entry 'pretty_a' with no version specified. This will cause build failures and prevents proper dependency resolution and security auditing. Fix: Complete the dependency declaration with a valid version string, e.g., 'pretty_assertions = "1.4.0"' or remove it if unused.
• High · Unsafe Recursive File Extraction — src/adapters/zip.rs, src/adapters/tar.rs, src/adapters/decompress.rs. The codebase recursively extracts and processes archives (zip, tar, tar.gz, etc.). Without proper validation, this could be vulnerable to zip bombs, tar bombs, and path traversal attacks (e.g., ../../../etc/passwd in archived file paths). Fix: Implement strict validation: (1) Enforce archive depth limits, (2) Validate extracted file paths to prevent traversal, (3) Set memory/size limits for decompression, (4) Timeout long-running extractions, (5) Use sandboxing for untrusted archives.
• High · SQLite Database Processing Without Input Validation — src/adapters/sqlite.rs. The SQLite adapter (src/adapters/sqlite.rs) processes untrusted database files. Malicious SQLite files could trigger vulnerabilities in the SQLite parser or cause denial of service through crafted queries or corrupted structures. Fix: Run SQLite processing in isolated processes/containers, implement resource limits (timeouts, memory), validate database integrity before processing, and consider using restrictive SQLite compile-time options.
• Medium · Use of Deprecated Crate: lazy_static — Cargo.toml (dependencies). The project uses 'lazy_static' which is deprecated in favor of 'std::sync::OnceLock' (stable in Rust 1.70+) or 'once_cell'. While not a direct vulnerability, it indicates potential code maintenance debt. Fix: Migrate from lazy_static to std::sync::OnceLock or once_cell crate to use actively maintained patterns.
• Medium · Potential Command Injection via FFmpeg Adapter — src/adapters/ffmpeg.rs. The ffmpeg adapter (src/adapters/ffmpeg.rs) may execute external processes. If user-controlled data reaches FFmpeg command construction without proper escaping, it could enable command injection attacks. Fix: Ensure all FFmpeg invocations use properly parameterized command execution (avoid shell interpretation), validate and sanitize all file paths and arguments, and run FFmpeg in restricted security contexts.
• Medium · Encoding Detection Without Validation — src/adapters/postproc.rs, encoding-related dependencies. The codebase uses 'encoding_rs' to handle multiple character encodings. Malicious files claiming specific encodings could cause parsing errors, information leaks, or crashes if encoding errors aren't properly handled. Fix: Implement proper error handling for encoding conversion failures, set strict encoding validation rules, and consider fuzzing with malformed encoded files.
• Medium · Temporary File Management — tempfile dependency usage across src/adapters/. The codebase uses 'tempfile' crate for temporary file creation. Race conditions or improper cleanup could lead to information disclosure or privilege escalation if temporary files contain sensitive data. Fix: Ensure all temporary files are created with restrictive permissions (0600), cleaned up immediately after use, and consider using ramdisks for sensitive temporary data.
• Low · Unspecified Edition Warning — Cargo.toml. The Cargo.toml specifies edition = "2024" which does not exist. The latest stable edition is 2021. This will cause build failures. Fix: Update to edition = "2021" (or 2024 once officially released by Rust team).
• Low · Missing Dependency Audit Configuration — .cargo/audit.toml, .. While .cargo/audit.toml exists, there's no evidence of regular dependency auditing in CI/CD or documented security update procedures. Fix: undefined

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/phiresky/ripgrep-all 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.
