# 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
|
|
|
|
|
|
|
|
You can use rga interactively. Add the following to your ~/.{bash,zsh}rc:
|
|
|
|
```bash
|
|
rga-fzf() {
|
|
RG_PREFIX="rga --files-with-matches --rga-cache-max-blob-len=10M $RGA_ARGS"
|
|
local file
|
|
file="$(
|
|
FZF_DEFAULT_COMMAND="$RG_PREFIX '$1'" \
|
|
fzf --sort --preview="rga --pretty --context 5 {q} {}" \
|
|
--phony -q "$1" \
|
|
--bind "change:reload:$RG_PREFIX {q}" \
|
|
--preview-window=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 cargo`
|
|
|
|
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
|
|
```
|
|
|
|

## 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**

**\--rga-list-adapters**

|
|
|
**\--rga-no-cache**

> 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.

## 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.
