Using Emacs 72 - Customizing Elfeed
I made this video write after I made the openwith one so even though I don't mention anything in this video, I wanted to share some updates on dired and openwith.
I got a lot of suggestions on alternate ways to achieve the workflow I
was seeking - being able to open a file using an external viewer. One
person noted that under newer versions of Emacs, the
W key is bound
to the command
(browse-url-of-dired-file) which does exactly what I
wanted. Problem solved with no customizing or extra packages.
It's a good thing I got a solution when I did - I needed it. I've been
reviewing applications for my new Teacher Certification program. It's
a 21 credit graduate program that results in participants receiving a
brand spanking new New York State Computer Science teaching
license. The applications consist of a bunch of files incuding PDFs,
images (photos), doc and text files and source code samples. I've got
all the applications in a Google drive which I've downloaded and now I
can just drop into dired and go through each directory, hit
source code and it's loaded in an Emacs buffer and
W for everything
Now for today's video. It's about a small customization I made to the elfeed RSS reader. It's also about the advantages and limitations of Emacs built in documentation. I'm not particularly strong in elisp - I'm a dabbler at best but even so, using Emac's built in help I was able to get to elisp code that was very close to what I wanted to do and then customize it. It also looks at the limitations - there still some code that I looked at that I have no clue as to what it does.
Specifically, elfeed lets you open a link in an external brower by
b. That's how I like reading most of my feeds. I'll scroll
up and down and hit
b for what I want to read. The trouble is that
when you hit
b focus goes to the browser and at the same time,
elfeed marks the entry as read and advances. I want it not to mark as
read. After I made the video, I decided I also didn't want elfeed to
advance to the next story.
Here's what I did.
I went in to elfeed and instead of typing
b on an entry, I ran
(describe-key)~ which is bound to
C-h k. I then typed
revealed that it ran
elfeed-search-browse-url. I followed the
hyperlinks in the help to open
elfeed-search.el and found the
function. From there I just copied it over to my Emacs config, tweaked
it and voila, problem solved.
The video has all the details. Enjoy.
