# 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](https://github.com/phiresky/ripgrep-all/tree/master/exampledir/demo) 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:

```bash
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.
