This will run from tty, in case you are X/wayland broken, or running without GUI.

Only needs python3, urllib and xml.etree

Code:

#!/usr/bin/python

#Get the Arch Latest News

from xml.etree import ElementTree
from urllib import request
import re

#Make a user agent string for urllib to use
agent = ('Mozilla/5.0 (Windows NT 10.1; Win64; x64; rv:82.0) '
        'Gecko/20100101 Firefox/82.0')
        
user_agent = {'User-Agent': agent}

class MakeList():
    def __init__(self, url, fname):
    
        #Get the xml to parse
        req = request.Request(url, data=None, headers=user_agent)
        html = request.urlopen(req)
        tree = ElementTree.parse(html)
        root = tree.getroot()
        
        #Get tag data
        tagA = root.findall('./channel/item/title')
        tagB = root.findall('./channel/item/link')
        tagC = root.findall('./channel/item/description')
        tagD = []
        
        #Append lines with separator
        for a,b,c in zip(tagA,tagB,tagC):
            tagD.extend([a.text, b.text, c.text, '_' * 70])
       
        #Print and Write list to file
        with open(fname, 'a') as f:
           for line in tagD:
                print('%s\n' % re.sub('<[^>]*>', '', line))
                f.write('%s\n\n' % re.sub('<[^>]*>', '', line))
                
if __name__ == "__main__":
    
    #Urls, log names
    A = ('https://archlinux.org/feeds/news/', 'Arch_RSS.log')
        
    B = ('file:///local/file/archfeed.xml', 'test.log')
    
    #Choose RSS feed here
    url, fname = A

    MakeList(url, fname)

I'd replace that line with this:

Code:

try:
    from lxml import etree
    print('Running with lxml.etree')
except:
    try:
        import xml.etree.ElementTree as etree
        print('Running with ElementTree')
    except:
        print('Failed to import ElementTree')

...

Code:

        tree = etree.parse(html)

But actually, I'd rather parse an RSS feed with Xidel:

Code:

#!/bin/bash

url='https://archlinux.org/feeds/news'
cols=${COLUMNS:-70}

line(){ l={1..$cols};eval printf -- $1%.0s $l;echo;}

eval $(xidel --output-format=bash -s "$url" 2>/dev/null \
  -e 'title:=//title' -e 'link:=//link' -e 'desc:=//description')

for (( i=0; i<${#title[@]}; i++ ))
do
  line '='
  echo "${title[$i]}"
  echo "${link[$i]}"
  line '-'
  echo "${desc[$i]}"|html2text -b$cols
done

or just read it in something like Newsboat or Canto.

Or use informant as a pacman hook.
Or one of those AUR/pacman helpers that also check the news for you.

This alias works for me, for now:

Code:

alias syu='w3m -dump https://www.archlinux.org/news/ | grep -A1 Published && sudo pacman -Syu'
