RSS all the things!

ratt is a tool for converting websites to rss/atom feeds. It uses config files which define the extraction of the feed data by using css selectors, or Lua script.

Config files are in yaml format:

#for automatic extraction, ratt checks all config files and matches the regex
regex: https://videoportal.joj.sk/.*
    #settings for all http requests for the website
        cookie: {}
        header: {}
        useragent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.72 Safari/537.36
    #css selectors to get the feed data
        title: .title.my-2
        desctription: .description
    #css selectors to get item data
        #the item container
        container: article.b-article.title-xs.article-lp
        #all subsequent attributes of the item are selected from the subtree of the item container
        title: div.content > h3
        link: a
        linkattr: href
        created: .date
        createdformat: 2.1.2006
        description: div.col > .date
        image: img.img-fluid
        imageattr: data-original


Config files are yaml files. ratt has some confs embedded. When calling eg: ratt auto https://1337x.to/top-100 ratt will try to find the config for the website url, it searches the embedded config files, the current directory and in ~/.config/ratt/*.yml.


Install latest with go:

go get git.sr.ht/~ghost08/ratt@latest

Install on Arch Linux from AUR with your favorite helper:

yay -S ratt-git


File bugs and TODOs through the issue tracker or send an email to ~ghost08/ratt@todo.sr.ht. For general discussion, use the mailing list: ~ghost08/ratt@lists.sr.ht.


ratt has three commands:

auto - automatically searches for the config that will be used.

extract - with other arguments, ratt will scrap the website to generate the RSS/Atom feed.

save - when you have the correct css selectors/lua scripts, save the config to a yaml file

ratt save --feed-title=".featured-heading strong" --item-container=".table-list-wrap tbody tr" --item-title="a:nth-child(2)" --item-link='a = sel:find("a:nth-child(2)")
itemURL = "https://1337x.to" .. a:attr("href")
doc, err = goquery.newDocFromURL(itemURL)
if err ~= nil then
link = doc:find("ul li a[onclick]"):first():attr("href")
link = link:gsub("%s+", "")
print(link)' --item-created=".coll-date" --item-created-format="" "https://1337x.to/.*" 1337x.yml

What will I do with this RSS feed?

That's a very good question. I'm happy you asked :)

You might feed the feed directly to photon, which is a modern RSS/Atom reader. photon will play you the media from your feed. It uses mpv and youtube-dl to automaticaly play videos, download torrents, view images and much more :)

So try this out:

ratt auto https://1337x.to/top-100 | photon -

If a css selector isn't enough to select the needed data, every feed and item attribute can be written as a multiline value and ratt will interpret it as Lua script.

The Lua script will get some global variables, to help with the extraction:

goquery is a module imported by default and it is a subset of the famous goquery library

sel is the selection object of the feed/item container on which it can be queried for the selectors

gojq is a module imported by default, it is the gojq) library

setGlobal sets a global variable that will be visible in other lua scripts. eg. in feed title setGlobal("myvar", 1) is called and than in every subsequent item title, item link, ..., item image the variable will be visible print(myvar)

index number of the item processed

ratt will take the stdout of the Lua script and insert it as the data of the feed/item. When a error has occured, just use the error function.


Calling another link, parsing it to a goquery.Document and querying the new doc:

  #select the item container html element
  container: .table-list-wrap tbody tr
  #select the title element in the item container
  title: a:nth-child(2)
  #lua script
  link: |-
    --sel is the item container element, find <a/>
    a = sel:find("a:nth-child(2)")
	--get the href attribute of <a/> and make a item url link from it
    itemURL = "https://1337x.to" .. a:attr("href")
	--request and parse the document
    doc, err = goquery.newDocFromURL(itemURL)
    if err ~= nil then
	  --return error if the request was unsuccesfull
	--find the item link you want
    link = doc:find("ul li a[onclick]"):first():attr("href")
	--trim space characters
    link = link:gsub("%s+", "")
	--and finally print the link out so ratt can include it in the item.link

You can also parse and query json data, with the help of the awesome gojq) library:

    title: .title
    description: |-
        --find the <script> element where the json data is
        script = sel:find("script"):first():text()
        index = script::find("var myJsonData =")
        --cut of the "var myJsonData =" prefix
        jsonData = script:sub(index+16)
        --parse a gojq query, that will find the obj["description'] value
        query, err = gojq.parse(".description")
        if err ~= nil then
        --expecting that the input data is a map/object (otherwise if it's a array use runArray)
        desc, err = query.runMap(jsonData)
        if err ~= nil then

Check the confs dir for other examples.


ratt needs config files for it to run. I really rely on the community to create configs for all the sites!

So please create config files, push it here, than everybody can make the world RSS again!
