Wow, just running GUI Emacs is so much easier.

Did you mean counsel-compile?

I should try that!

I use it in all buffers whose major mode is derived from text-mode.

By default undo does work in the scratch buffer so it is something in your configuration that is keeping this from working. As a quick way to check, try running emacs -q, which skips loading your configuration, and see if you have undo in the scratch buffer there; if so, it’s definitely something you have in you configuration.

You can bisect your configuration to figure out how you are deactivating undo. You can do this manually or with the help of the bug-hunter package.

What’s with all the occurrences of \n?

Acme doesn’t stand for some generic editor! It’s the famous acme text editor by Rob Pike. It’s an interesting editor, very different from Emacs or Vim, and yes, very mousey. In this video Russ Cox gives a great overview: https://youtu.be/dP1xVpMPn8M

I tried logging into codeberg to create some issues, but apparently I don’t know my password anymore and codeberg’s “Forgot password?” link is broken (it says it sent me an email but those are lies). So instead I’ll just mention the issues I’ve found here (sorry to monopolize this thread so much), for @[email protected]:

1. It seems like my GPG troubles were all solved by (setq epg-pinentry-mode 'loopback), maybe this should be mentioned in the documentation.

2. I don’t think lem.el needs to depend on an external program to render markdown. Instead I suggest just using markdown-mode’s fontification, which is a dependency anyway!

3. I’m not too fond of the emojify dependency either. I have a font with very nice emojis, why do I also need emojfiy downloading tons of images of emojis? Just use the unicode emoji characters directly.

4. So many useful lem commands are unbound! There isn’t even a keybinding to reply to post or comments! It seems like all the commands I would want exist, they just aren’t bound in lem-mode-map.

5. With the code I first cloned from codeberg, the command lem-ui-jump-to-subscribed showed all my communities as options, then I updated and now it seems that if several communities have the same name (I’m subscribed to emacs both on communick.news and on lemmy.ml, for example), only one gets shown as an option.

I think that’s it. All in all I’m really enjoying the package, these are really minor complaints.

I looked at the macro expansion of the form you wrote and it looks like gibberish, so I don’t think the :hook keyword allows expressions to be used as hooks, you need to define a function and use the function name:

(use-package pascal ; presumably
  :init
  (defun remove-pascal-completions ()
    (remove-hook 'completion-at-point-functions
                 'pascal-completions-at-point t))
  :hook (pascal-mode . remove-pascal-completions))

Also, the weird single quote character you used probably doesn’t work in Emacs (but maybe you have normal single quotes in your file and it’s just lemmy’s markdown messing things up).

Oh, found a new bug: if you are subscribed to communities with the same name on different lemmy instances, lem-ui-jump-to-subscribed will only show you one of them. It used to show all of them before I pulled the latest changes today. (I’m subscribed to communities named emacs on communick.news and on lemmy.ml)

I think the entire problem is that I had epg-pinentry-mode set to nil, I changed it to 'loopback and now things seem to be working properly. I don’t understand why lem.el uses a passphrase with GPG while it seems like mastodon.el doesn’t. Let’s see if posting this via lem.el works!

EDIT: Yep, it worked and editing comments works too! By the way, tons of unbound commands like lem-ui-edit-comment deserve key bindings.

I’ll post a back trace later. I understand the dependence on markdown-mode, but why also an external markdown executable? You could just let markdown-mode fontify the text and people can hide the markup symbols if they like. I use markdown-mode a lot and it never once occurred to me that I needed a markdown converter.

EDIT: Things seem to be working now that I have epg-pinentry-mode set to 'loopback, so I won’t post the backtrace after all.

I can see posts in lem! I guessed correctly that issue with GPG was that it really, really wanted a tty, so I tried logging in from emacs -nw and that worked. Once the credentials are stored I can use lem from GUI Emacs! Apparently I need to install some markdown executable… I faked it with ln -s /bin/cat ~/bin/markdown and everything is hideous but useable! 😛

I tried posting this comment from lem and it seemed to work but I can’t seem to see it here, so I’m posting again from the browser. I’m getting closer and closer to lem working and am very excited.

EDIT: spoke too soon, now I get DEcryption errors even in emacs -nw. Maybe I’m out of my depth here.

I get that EXWM is not the minimalist experience Howard is going for here, but I do wonder if he’s tried it.

Does that ioctl error in my sibling comment sound like GPG is expecting me to type the password at a tty instead of Emacs or something like that?

Does this help? With debug on error I get two hidden buffers:

*epg* contains:

Process epg exited abnormally with code 2
[GNUPG:] NEED_PASSPHRASE_SYM 9 3 2
[GNUPG:] PINENTRY_LAUNCHED 10719 curses 1.1.0 - dumb :0
[GNUPG:] ERROR get_passphrase 32870
[GNUPG:] CANCELED_BY_USER
[GNUPG:] FAILURE symencrypt 33554531

And *epg-error* contains:

gpg: problem with the agent: Inappropriate ioctl for device
gpg: error creating passphrase: Operation cancelled
gpg: symmetric encryption of '[stdin]' failed: Operation cancelled

It’s a little weird that the default theme is technically not a theme. Maybe Emacs should just ditch the code that goes into setting up the default “theme” and use these actual themes instead.

Well, I keeping getting an error message that says: plstore–insert-buffer: GPG error: “Encrypt failed”, “Exit”.

Do I need to install a GPG executable or a GPG library? What is it even trying to Encrypt, can I turn that off? Why doesn’t mastodon.el give me the same error?

Blatant advertising for one of my packages: Embark has convenient key bindings for all of the commands discussed in this article. If point is on active region and you call embark-act, the s prefix has all of the sort commands there, reverse-region is on r, and delete-duplicate-lines is on d. I tend to forget all the sort commands, so I often call embark-act on a region, press s, and then C-h to get a list of them.

I couldn’t quickly get this to work, but I’ll try harder later. I love mastodon.el by the same person.
