Multiple Cursors keybinds

The Multiple Cursors package has been given much praise throughout the Emacsphere. It has a smaller use-case than keyboard macros, but it is usually quicker and just plain looks awesome. To make full use of its commands, I combine two of the concepts I've explained here before, rebinding M-number and intuitive keymaps. [...]

Better time-stamps in org-export

org-mode has a very useful command, org-time-stamp, which helps you insert dates from a calendar. So you can quickly type C-c . RET to insert <2015-10-05 Mon>, for instance. These time-stamps are used by Org in a variety of ways, so they are wrapped in <> to make them easy to parse. The downside being that they look less than optimal when exported. [...]

Predicting the future with M-n

This is one of those small functionalities that makes your life considerably easier, and yet a surprising number of people don’t know about it. When Emacs prompts you for something in the minibuffer, you might be aware that you can navigate back and forth in the prompt’s history with M-p and M-n, but did you know you can even step into the future? [...]

Flycheck a directory and report the results

This weekend I found myself doing some heavy-weight refactoring in CIDER. This is the kind of situation where Flycheck helps a lot, but I still needed it to do a bit more. Every time I made a significant change to a file, I had to visit 3 or 5 other files and trigger Flycheck on each one of them. It wasn’t long before I decide there had to be a way to just Flycheck a whole directory. [...]

Improving page (section) navigation

If you’ve taken the time to browse some Elisp source files, you’ve no doubt run into that odd little ^L, a.k.a. the form feed character. Emacs uses these white space characters as page delimiters. This makes for a very convenient way to split a file into sections, and quickly navigate between them. I won’t go too deep into them, as Eric James has already written a great crash course on pages that you should go check out. [...]

Donations, donations, donations

Every computer user, to some extend, is a user of Open Source Software (even if most of them are oblivious to that). This is only possible because the developers of these pieces of software have donated their time to us, who are nothing short of complete strangers to them. These are regular people, with just as much free time as you or I—sometimes a bit more, sometimes even less. [...]

Nameless, less is more

Nameless is an Emacs package for hiding namespace prefixes in elisp code. It is a short and simple minor-mode that changes the display, without changing the contents of the buffer. Using it is as simple as turning it on, there’s no need to change your package in any way. [...]

Org-mode subtrees and file-local variables

As you grow accustomed to fine-tuning your Emacs experience, it’s not unusual to start using local variables in your files. These are specified as comment lines at the end of the file, and are extremely practical in a number of scenarios. Here’s a very simple org file. [...]

Making Ispell work with org-mode

If you’ve every tried to do some spell-checking in org-mode you know how finicky that can be. Ispell is happy to check absolutely anything, even code blocks and property drawers! When you’re blogging about code-snippets from an org file this annoyance quickly turns into irritation. Here’s how you fix it. [...]

A comment-or-uncomment-sexp command

Commenting is a very frequent piece of a programmer’s workflow, and it’s important to make it seamless and simple. For the more statemental languages, that’s as easy as writing a custom comment-line command. However, when you’re writing in Lisp languages, that just won’t do. Trying to comment out lines in a sexp-oriented structure, feels a lot like trying to hit a nail with a heavy screwdriver—it sometimes gets the job done, but it mostly just leads to frustration. [...]

Markdown style link IDs in org-mode

Link handling and exporting is one of the most versatile aspects of org-mode. Did you know you can make org-mode understand Markdown style link IDs? [some-id]: http://example.com/ [...]

Transposing keybinds in Emacs

Transposing is another of those features that I really miss when not in Emacs. It took me several months of actively reminding myself in order to finally incorporate it into my regular arsenal. Now, not a day goes by that I don’t transpose a few lines, and usually some words and sexps as well, but the usefulness of transpose-char still seems to elude me. [...]

Embedding Youtube videos with org-mode links

If you’re a frequent reader, no doubt you noticed an embedded Youtube video on a post a couple of weeks ago. Youtube makes it pretty simple to embed videos, they give you the entire iframe HTML code to use, but this wouldn’t really be Emacs if we couldn’t make things just a little bit easier. Just add the snippet below to your init file, and you’re good to go. [...]

Fixing DOuble CApitals as you type

This is something that’s bothered me for a very long time. My pinky is slow when it comes to releasing the Shift key, and frequently leads to typos. MOst typos (hitting letters in the wrong order) are already covered by auto-correction, but there’s another common typo that it doesn’t fix. EVery now and then, I’ll start a sentence with two uppercase letters. [...]

You won’t believe this simple trick for using Emacs with Java!

Install JDEE! Ok, maybe that’s an overstatement. JDEE is far from simple, and it hasn’t been able to keep up very well since Java 1.4. However, thanks to Stephen Leake & folks, that might be starting to change. JDEE is now on Github, and it could definitely use your help. [...]
