# rrip - Bulk-download images from subreddits



Program to bulk-download image from reddit subreddits.



## Features



* Set max size of file, max total size, minimum score etc..



* Download images from Reddit preview links instead of source, saving some space.



* If the image / GIF is already downloaded in same folder, skip it.



* Log final download URLs to a file using a custom format string.



* Filter by post title or link using regular expression.



* Use Go template syntax to do custom filtering over post properties, or change file name format.



* Single static binary written in Golang



(Note: I have not tested all combinations of features, you might encounter some bugs!)



## Install

### Using `go` command

Assuming you have Go toolchain installed



```

go install github.com/mahesh-hegde/rrip@latest

```



### From Release section

Download from Release section and unpack the binary executable somewhere in your `PATH`.



### Using Docker / Podman

`rrip` is also available as a lightweight (distroless) [Docker image](https://ghcr.io/mahesh-hegde/rrip) from ghcr.io.



Running from docker image obviously requires a bind mount and setting the user. So you can use an alias like this.



```bash

alias rrip='docker run --rm -v $PWD:/app/ -u $(id -u):$(id -g) ghcr.io/mahesh-hegde/rrip:latest'

```



Then invoke it as `rrip`.



In case of rootless `podman`, specifying user & group is not required due to uid remapping. So alias will be:



```bash

alias rrip='podman run --rm -v $PWD:/app/ ghcr.io/mahesh-hegde/rrip:v0.5'

```



## Options

Invoke `rrip` without arguments for up-to-date usage output.



## TL;DR



```sh

## Download only <200KB files from r/Wallpaper

rrip --max-size=200 r/Wallpaper



## Download all time top from r/WildLifePhotography, without exceeding 20MB storage or 50 files

rrip --max-storage=20 --max-files=50 --sort=top-all r/WildlifePhotography



## Search "Neon" on r/AMOLEDBackgrounds and download top 20, sorted by top voted in past one year

rrip --search="Neon" --max-files=20 --sort=top-year r/AMOLEDBackgrounds



## Download memes from r/LogicGateMemes, download reddit previews (640p)

## instead of original image, for space savings.

## Also log all image links to file called meme.txt along with title



## Note that -preview-res cannot be arbitrary

## Ones that generally work are 1080, 960, 640, 360, 216, 108

## If no suitable preview is found, image won't be downloaded



## use -prefer-preview instead of -download-preview 

## to download original URL if no preview could be found



rrip --download-preview --preview-res=640 --data-output-file=meme.txt --data-output-format="{{.final_url}} {{.title}}" r/LogicGateMemes



## Log all image links from r/ImaginaryLandscape

## without downloading files, using -d (dry run) option.

## (Reddit shows last 600 or so.., not really "all")

rrip -d --data-output-file=imaginary_landscapes.txt --data-output-format="{{.score}} {{.final_url}} {{.quoted_title}} {{.author}}" r/ImaginaryLandscapes

```



### Using template options

Go `text/template` syntax can be used to do versatile filtering. It can also be used to do formatting of logged links.



```sh

## Inspect the JSON of post using --print-post-data

rrip --print-post-data --max-files=1 r/AMOLEDBackgrounds



## After inspecting the JSON, you can use the field values in `-template-filter` to filter based on any attribute.

## If the template evaluates to "false", "", or "0", the post will be skipped by rrip



## Example: only download gilded posts

rrip --template-filter='{{gt .gilded 0.0}}' --max-files=20 --sort=top-year r/AMOLEDBackgrounds



## Example: only download posts by a given author, say u/temporary_08

rrip --template-filter='{{eq .author "temporary_08"}}' --max-files=20  r/AMOLEDBackgrounds



## Example: skip potentially unsafe content

rrip --template-filter='{{not .over_18}}' --max-files=20  r/AMOLEDBackgrounds



## Example: Log links to a file with author, upvote ratio, and quoted title.

## Use dry run (-d) to skip download

rrip -d --data-output-file=amoled.txt --data-output-format='{{.upvote_ratio}} {{.author}} {{.quoted_title}}' r/AMOLEDBackgrounds



## Example: Change file name format using Go templates.

rrip --filename-format='{{.author}} {{.title}} {{.score}}' r/AMOLEDBackgrounds

```



## Caveats

* Can't handle crossposts when downloading preview image.

* No support for downloading albums.

* Some options don't work together

* Many other caveats I don't remember.
