# 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 via fzf. Add the following to your ~/.{bash,zsh}rc:
|
|
|
|
```bash
|
|
rga-fzf() {
|
|
RG_PREFIX="rga --files-with-matches"
|
|
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"
|
|
}
|
|
```
|
|
|
|
And for your `~/.config/fish/config.fish`:
|
|
```
|
|
function rga-fzf
|
|
set RG_PREFIX 'rga --files-with-matches'
|
|
if test (count $argv) -gt 1
|
|
set RG_PREFIX "$RG_PREFIX $argv[1..-2]"
|
|
end
|
|
set -l file $file
|
|
set file (
|
|
FZF_DEFAULT_COMMAND="$RG_PREFIX '$argv[-1]'" \
|
|
fzf --sort \
|
|
--preview='test ! -z {} && \
|
|
rga --pretty --context 5 {q} {}' \
|
|
--phony -q "$argv[-1]" \
|
|
--bind "change:reload:$RG_PREFIX {q}" \
|
|
--preview-window='50%:wrap'
|
|
) && \
|
|
echo "opening $file" && \
|
|
open "$file"
|
|
end
|
|
```
|
|
|
|
## INSTALLATION
|
|
|
|
Linux x64, macOS and Windows binaries are available [in GitHub Releases][latestrelease].
|
|
|
|
[latestrelease]: https://github.com/phiresky/ripgrep-all/releases/latest
|
|
|
|
### Linux
|
|
|
|
#### Arch Linux
|
|
|
|
`pacman -S ripgrep-all`.
|
|
|
|
#### Nix
|
|
`nix-env -iA nixpkgs.ripgrep-all`
|
|
|
|
#### Debian-based
|
|
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
|
|
```
|
|
|
|
Note that installing via chocolatey or scoop is the only supported download method. If you download the binary from releases manually, you will not get the dependencies (for example pdftotext from poppler).
|
|
|
|
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 --locked ripgrep_all
|
|
~$ rga --version # this should work now
|
|
```
|
|
|
|

## 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.
