# sfeed show mastodon toot title
2024-02-20T14:03:20Z

I use sfeed to read feeds, and I love it.
=> https://codemadness.org/sfeed.html

I also prefer to follow people on mastodon with the associated rss feed, I mean https://instance.tld/@username.rss.

However, this rss feed don't have a title, resulting of the publication date displayed in sfeed_curses.
Even if I can read the toot when pressing enter, I'd like to see a preview of the toot.

sfeed is so good that you can write you own filter() function.
So now, in my sfeedrc, I have:

```
filter() {
	case "$1" in
	masto*:*)
		# don't insert date in title, just first line
		awk -F '\t' 'BEGIN { OFS = "\t"; }
		{
			# turn description into title
			$2 = gensub("<[^>]+>", " ", "G", $4)
			print $0
		}
		'
		;;
```

It isn't perfect, but give a nice preview:

Of course, I have to name mastodon feeds with "masto<someting>:otherthing" like this:

```
feed 'masto:drewdevault@fosstodon.org' 'https://fosstodon.org/@drewdevault.rss'
feed 'masto:fredg@pouet.chapril.org' 'https://pouet.chapril.org/@fredg.rss'
feed 'masto:ploum@mamot.fr' 'https://mamot.fr/@ploum.rss'
feed 'masto:noroanka@im-in.space' 'https://im-in.space/@noroanka.rss'
feed 'masto:solene@bsd.network' 'https://bsd.network/@solene.rss' "" "iso-8859-1"
feed 'mastotag:solarpunk' 'https://im-in.space/tags/solarpunk.rss'
feed 'mastotag:openbsd' 'https://im-in.space/tags/openbsd.rss'
```

You you're interesed, here is the full filter() I use now:

```
filter() {
	case "$1" in
	masto*:*)
		# don't insert date in title, just first line
		awk -F '\t' 'BEGIN { OFS = "\t"; }
		{
			# turn description into title
			$2 = gensub("<[^>]+>", "", "G", $4)
			print $0
		}
		'
		;;
	"xkcd.com")
		# do not turn html with w3m/lynx -dump to get img url
		awk -F '\t' 'BEGIN { OFS = "\t"; }
		{
			$5 = "plain";
			# extract img url
			match($4, "src=\"(.+)");
			imglink = substr($4, RSTART,RLENGTH);
			split(imglink , a, "\"");
			imglink = a[2];
			# same with alt
			match($4, "alt=\"(.+)");
			alt = substr($4, RSTART,RLENGTH);
			split(alt , a, "\"");
			alt = a[2]
			# append img link at the end
			$4 = sprintf("%s \\n=> %s", alt,  imglink);
			print $0
			# download the img
			#cmd = sprintf("cd /home/prx/lessernet/box/; curl -O -s -L -H 'User-Agent:' '%s'", imglink)
			#system(cmd)
		}
		'

	*)
		cat

	function filterlink(s) {
		# protocol must start with http, https or gopher.
		if (match(s, /^(http|https|gopher):\/\//) == 0) {
			return "";
		}

		# shorten feedburner links.

		return s
	}
	{
		$3 = filterlink($3); # link
		$8 = filterlink($8); # enclosure

		# try to remove tracking pixels: <img/> tags with 1px width or height.
		gsub("<img[^>]*(width|height)[[:space:]]*=[[:space:]]*[\"'"'"' ]?1[\"'"'"' ]?[^0-9>]+[^>]*>", "", $4);

		print $0;
	}'
}
```
