rga: ripgrep, but also search in PDFs, E-Books, Office documents, zip, tar.gz, etc.

rga is a line-oriented search tool that allows you to look for a regex in a multitude of file types. rga wraps the awesome ripgrep and enables it to search in pdf, docx, sqlite, jpg, movie subtitles (mkv, mp4), etc.

For more detail, see this introductory blogpost: https://phiresky.github.io/blog/2019/rga--ripgrep-for-zip-targz-docx-odt-epub-jpg/

rga will recursively descend into archives and match text in every file type it knows.

Here is an example directory with different file types:

demo/
├── greeting.mkv
├── hello.odt
├── hello.sqlite3
└── somearchive.zip
├── dir
│ ├── greeting.docx
│ └── inner.tar.gz
│ └── greeting.pdf
└── greeting.epub

Available Adapters

rga --rga-list-adapters

Adapters:

Adapters:

• ffmpeg

  Uses ffmpeg to extract video metadata/chapters and subtitles

  Extensions: .mkv, .mp4, .avi

• pandoc

  Uses pandoc to convert binary/unreadable text documents to plain markdown-like text

  Extensions: .epub, .odt, .docx, .fb2, .ipynb

• poppler

  Uses pdftotext (from poppler-utils) to extract plain text from PDF files

  Extensions: .pdf

• zip

  Reads a zip file as a stream and recurses down into its contents

  Extensions: .zip

  Mime Types: application/zip

• decompress

  Reads compressed file as a stream and runs a different extractor on the contents.

  Extensions: .tgz, .tbz, .tbz2, .gz, .bz2, .xz, .zst

  Mime Types: application/gzip, application/x-bzip, application/x-xz, application/zstd

• tar

  Reads a tar file as a stream and recurses down into its contents

  Extensions: .tar

• sqlite

  Uses sqlite bindings to convert sqlite databases into a simple plain text format

  Extensions: .db, .db3, .sqlite, .sqlite3

  Mime Types: application/x-sqlite3

The following adapters are disabled by default, and can be enabled using '--rga-adapters=+pdfpages,tesseract':

• pdfpages

  Converts a pdf to it's individual pages as png files. Only useful in combination with tesseract

  Extensions: .pdf

• tesseract

  Uses tesseract to run OCR on images to make them searchable. May need -j1 to prevent overloading the system. Make sure you have tesseract installed.

  Extensions: .jpg, .png

USAGE:

rga [FLAGS] [OPTIONS] PATTERN [PATH ...]

FLAGS:

--rga-accurate

Use more accurate but slower matching by mime type

By default, rga will match files using file extensions. Some programs, such as sqlite3, don't care about the file extension at all, so users sometimes use any or no extension at all. With this flag, rga will try to detect the mime type of input files using the magic bytes (similar to the `file` utility), and use that to choose the adapter. Detection is only done on the first 8KiB of the file, since we can't always seek on the input (in archives).

-h, --help

Prints help information

--rga-list-adapters

List all known adapters

--rga-no-cache

Disable caching of results

By default, rga caches the extracted text to a database in ~/.cache/rga if it is small enough. This way, repeated searches on the same set of files will be much faster. If you pass this flag, all caching will be disabled.

--rg-help

Show help for ripgrep itself

--rg-version

Show version of ripgrep itself

-V, --version

Prints version information

OPTIONS:

--rga-adapters=<adapters>...

Change which adapters to use and in which priority order (descending)

"foo,bar" means use only adapters foo and bar. "-bar,baz" means use all default adapters except for bar and baz. "+bar,baz" means use all default adapters and also bar and baz.

--rga-cache-compression-level=<cache-compression-level>

[default: 12]

--rga-cache-max-blob-len <cache-max-blob-len>

Max compressed size to cache

Longest byte length (after compression) to store in cache. Longer adapter outputs will not be cached and recomputed every time. [default: 2000000]

--rga-max-archive-recursion=<max-archive-recursion>

Maximum nestedness of archives to recurse into [default: 4]

-h shows a concise overview, --help shows more detail and advanced options.

All other options not shown here are passed directly to rg, especially [PATTERN] and [PATH ...]

Development

To enable debug logging:

export RUST_LOG=debug
export RUST_BACKTRACE=1

Also rember to disable caching with --rga-no-cache or clear the cache in ~/.cache/rga to debug the adapters.
