Weekly Tips, Tricks, &c. Thread

This is a thread for smaller, miscellaneous items that might not warrant a full post on their own. [See this search for previous "Weekly Tips, Tricks, &c." Threads.](https://www.reddit.com/r/emacs/search?q=Weekly+tips&restrict_sr=on&sort=new&t=all) Don't feel constrained in regards to what you post, just keep your post vaguely, generally on the topic of emacs.

Wrote this, so I could have a single unified tagging command, whatever I'm doing with org: (defun my/org-roam-add-current-tags (&optional arg) "Add tags to current headline or node, depending on location. If not in an org-roam node, behave exactly like `org-set-tags-command'. Otherwise (that is, in an org-roam node), if in a headline, set tags for that headline. If not in a headline, or with a prefix ARG, set tags for whole node." (interactive "P") (cond ;; Not in an org-roam node, revert to standard behaviour ((not (org-roam-file-p)) (org-set-tags-command arg)) ;; roam node and at a heading (and no arg) -- set heading tags ((and (not arg) (org-get-heading)) (org-set-tags-command)) ;; roam node, not in a headline (or with prefix arg) -- set ;; roam-node tags. (t (call-interactively #'org-roam-tag-add))))

If you are maintaining any package in Fedora, you probably often run `rpmdev-bumpspec /path/to/your/foo.spec` command. It annoyed me to always switch to a terminal because of that, so I wrote a very simple Emacs commands for it. (defun frostyx/rpmdev-bumpspec () (interactive) (shell-command (string-join (list "rpmdev-bumpspec" buffer-file-name) " "))) (defun frostyx/rpmdev-bumpspec-new-version (version) (interactive "sNew version: ") (shell-command (string-join (list "rpmdev-bumpspec" buffer-file-name "--new" version) " ")))

I finally got around to writing a small README for my Emacs config, highlighting some homegrown parts that I really like. I reckon most of these things are pretty standard, but maybe some people here still find it useful: https://gitlab.com/slotThe/dotfiles/-/tree/master/emacs/.config/emacs

Does anyone rebind the exit chord \`C-x C-c\` to something else? I've exited emacs on accident when I my finger falls between the `x` and `c` keys and I was curious what others rebind the exist chord to?

You can define a dumb lambda command and then bind the chord to it.

`ignore` is a command. No need for a lambda.

I just found out that you can enable imenu inside pdf-tools buffers really easily. I've been pressing 'o' for years to get a pdf outline, which works fine, but I like imenu more, since I've got it hooked into vertico and can do completing-read to get to the heading I want. I've also made it so that imenu completing-read opens up in a 'buffer indexed' type of vertico buffer. The effect is that imenu opens off to the side, like the original pdftools index. I'll post the snippets here: \+ vertico customisation for imenu: `(vertico-multiform-mode)` `;; Configure the display per command.` `;; Use a buffer with indices for imenu` `(setq vertico-multiform-commands` `'((consult-imenu buffer indexed)))` \+ enable imenu in pdftools buffers: `(add-hook 'pdf-tools-enabled-hook #'pdf-outline-imenu-enable)` Hope it makes someone's experience better. Thank you to the package creators and maintainers for this functionality.

FYI in the future, if a mode does not provide imenu support (or you want to customize it), it's pretty straightforward. It's basically just a list of regexes. See `imenu-generic-expression`: https://www.gnu.org/software/emacs/manual/html_node/elisp/Imenu.html

Could anyone please help me with the following Evil-mode issue? Somehow it stopped copying/pasting to/from system clipboard (MacOS) via \`+\` register. Pretty sure it used to work. But now when I copy something into system clipboard then do "+p in Emacs it says "+ register is empty"

You can keep the binding, while avoiding unwanted exits: `(setq confirm-kill-emacs 'y-or-n-p)`

Did firefox suddenly stop overriding C-n and opening a new window? Because C-n suddenly works. Is this a dream? Did I configure something that fixed it and forgot that I did it? Like in some kind of late night haze of trying to avoid real work? Was it an update?

IT IS AMAZING HOW MUCH BETTER THIS HAS MADE MY LIFE.

Does anyone know how to add a column of numbers having commas in a org-mode table? \`vsum\` does not work when the numbers have commas.

This is great, thank you!
