# 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
```

## Integration with fzf

![rga-fzf](doc/rga-fzf.gif)

You can use rga interactively via fzf. Add the following to your ~/.{bash,zsh}rc:

```bash
rga-fzf() {
	RG_PREFIX="rga --files-with-matches --rga-cache-max-blob-len=10M"
	local file
	file="$(
		FZF_DEFAULT_COMMAND="$RG_PREFIX '$1'" \
			fzf --sort --preview="[[ ! -z {} ]] && rga --pretty --context 5 {q} {}" \
				--phony -q "$1" \
				--bind "change:reload:$RG_PREFIX {q}" \
				--preview-window="70%:wrap"
	)" &&
	echo "opening $file" &&
	xdg-open "$file"
}
```

## INSTALLATION

Linux x64, macOS and Windows binaries are available [in GitHub Releases][latestrelease].

[latestrelease]: https://github.com/phiresky/ripgrep-all/releases/latest

### Linux

On Arch Linux, you can simply install from AUR: `yay -S ripgrep-all`.

On Debian-based distributions you can download the [rga binary][latestrelease] and get the dependencies like this:

`apt install ripgrep pandoc poppler-utils ffmpeg`

If ripgrep is not included in your package sources, get it from [here](https://github.com/BurntSushi/ripgrep/releases).

rga will search for all binaries it calls in \$PATH and the directory itself is in.

### Windows

Install ripgrep-all via [Chocolatey](https://chocolatey.org/packages/ripgrep-all):

```
choco install ripgrep-all
```

If you get an error like `VCRUNTIME140.DLL could not be found`, you need to install [vc_redist.x64.exe](https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads).

### Homebrew/Linuxbrew

`rga` can be installed with [Homebrew](https://formulae.brew.sh/formula/ripgrep-all#default):

`brew install rga`

To install the dependencies that are each not strictly necessary but very useful:

`brew install pandoc poppler tesseract ffmpeg`

### Compile from source

rga should compile with stable Rust (v1.36.0+, check with `rustc --version`). To build it, run the following (or the equivalent in your OS):

```
   ~$ apt install build-essential pandoc poppler-utils ffmpeg ripgrep cargo
   ~$ cargo install ripgrep_all
   ~$ rga --version    # this should work now
```

## Available Adapters

```
rga --rga-list-adapters
```

<!-- this part generated by update-readme.sh -->

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  
     Mime Types: application/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 its individual pages as png files. Only useful in combination with tesseract  
     Extensions: .pdf  
     Mime Types: application/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 \[RGA OPTIONS\] \[RG OPTIONS\] 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, if it is small enough, to a
> database in \~/.cache/rga on Linux, _\~/Library/Caches/rga_ on macOS,
> or C:\\Users\\username\\AppData\\Local\\rga on Windows. 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\>

> ZSTD compression level to apply to adapter outputs before storing in
> cache db
>
> Ranges from 1 - 22 \[default: 12\]

**\--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. Allowed
> suffixes: k M G \[default: 2000000\]

**\--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 remember to disable caching with `--rga-no-cache` or clear the cache
(`~/Library/Caches/rga` on macOS, `~/.cache/rga` on other Unixes,
or `C:\Users\username\AppData\Local\rga` on Windows)
to debug the adapters.
