Emacs ABCs: A is for Apropos

Sometimes one gets the strangest ideas. I’ve had this kicking around in my brain for a few weeks. Since you read and re-read books to kids endless times anyway, why not learn more yourself along the way? For example, Emacs is something that is worth repeated learning. You forget commands, you rediscover them, you dig into them more. I think it might be interesting to have kid’s books with technical subtext. While you’re saying the letters and helping kids learn to read, you can silently (or not-so-silently!) read the notes, and pick one command to try later. In this case: M-x apropos?

A is for apropos

Here’s a list of interesting possibilities:

  • apropos

  • customize / compile / calc
  • dired, debug-on-entry
  • edebug-defun, eshell
  • fastnav, ffap, fixup-whitespace
  • grep-find, gnus
  • help-with-help, helm
  • ielm
  • just-one-space
  • keyboard macros, kmacro-start-macro, kbd-macro-query
  • load-library, locate-library, list-packages
  • magit, make-indirect-buffer
  • name-last-kbd-macro
  • occur (and occur-edit-mode); org
  • package-list-packages, picture-mode
  • quick-url, query-replace-regexp-eval
  • regexp-builder, recursive-edit, recover-this-file,
  • savehist-mode, server-start, smartparens

Crazy? Neat? =) What do you think?

Emacs beginner resources

Sometimes it’s hard to remember what it’s like to be a beginner, so I’m experimenting with asking other people to help me with this. =) I asked one of my assistants to look for beginner tutorials for Emacs and evaluate them based on whether they were interesting and easy to understand. Here’s what she put together! – Sacha

Emacs #1 – Getting Started and Playing Games by jekor
Probably the most helpful Emacs tutorial series on YouTube. Goes beyond the “what to type” how-tos that other tutorials seem bent on explaining over and over. Emphasizes games and how they help users familiarize themselves with the all-keyboard controls. 5/5 stars

Org-mode beginning at the basics
What it says on the tin. Essential resource for those who are new to Emacs and org-mode. Provides steps on how to organize workflow using org-mode written in a simple, nontechnical, writing style. 5/5 stars

Xah Emacs Tutorial
Though the landing page says that the tutorial is for scientists and programmers, beginners need not be intimidated! Xah Emacs Tutorial is very noob-friendly. Topics are grouped under categories (e.g. Quick Tips, Productivity, Editing Tricks, etc.) Presentation is a bit wonky though. 4.5/5 stars

RT 2011: Screencast 01 – emacs keyboard introduction by Kurt Scwehr
Keyboard instruction on Emacs from the University of New Hampshire. Very informative and also presents some of the essential keystrokes that beginners need to memorize to make the most out of the program. But at 25 mins, I think that the video might be too long for some people. 4/5 stars

Emacs Wiki
Nothing beats the original- or in this case, the official- wiki. Covers all aspects of Emacs operation. My only gripe with this wiki is that the groupings and presentation are not exactly user-friendly (links are all over the place!), and it might take a bit of time for visitors to find what they are looking for. 4/5 stars

Mastering Emacs: Beginner’s Guide to Emacs
The whole website itself is one big tutorial. Topics can be wide-ranging but it has a specific category for beginners.
whole website itself is one big tutorial. Looks, feels, and reads more like a personal blog rather than a straightforward wiki/tutorial. 4/5 stars

Jessica Hamrick’s Absolute Beginner’s Guide to Emacs
Clear and concise. Primarily focused on providing knowledge to people who are not used to text-based coding environments. It covers a lot of basic stuff, but does not really go in-depth into the topics. Perfect for “absolute beginners” but not much else. 3/5 stars

Jim Menard’s Emacs Tips and Tricks
Personal tips and tricks from a dedicated Emacs user since 1981. Not exactly beginner level, but there’s a helpful trove of knowledge here. Some chapters are incomplete. 3/5 stars

Emacs Redux
Not a tutorial, but still an excellent resource for those who want to be on the Emacs update loop. Constantly updated and maintained by an Emacs buff who is currently working on a few Emacs related projects. 3/5 stars

Jeremy Zawodny’s Emacs Beginner’s HOWTO
Lots of helpful information, but is woefully not updated for the past decade or so. 2/5 stars

This list was put together by Marie Alexis Miravite. In addition, you might want to check out how Bernt Hansen uses Org, which is also pretty cool.

Emacs Basics: Customizing Emacs

This entry is part 3 of 3 in the series Emacs Basics

Hello, I’m Sacha Chua, and this is an Emacs Basics video on customizing Emacs. Emacs is incredibly flexible. You can tweak it to do much more than you might expect from a text editor. This week, we’re going to focus on learning how to tweak Emacs with M-x customize and by editing ~/.emacs.d/init.el.


You can download the MP3 from Archive.org

Customize

You can change tons of options through the built-in customization interface. Explore the options by typing M-x customize. Remember, that’s Alt-x if you’re using a PC keyboard and Option-x if you’re on a Mac. So for me, that’s Alt-x customize <Enter>. In the future, I’ll just refer to this as the Meta key, so remember which key is equivalent to Meta on your keyboard. (Review – Emacs Basics: Call commands by name with M-x)

After you run M-x customize, you’ll see different groups of options. Click on the links to explore a group.

For example, people often want to change the backup directory setting. This is the setting that controls where the backup files (the files ending in ~) are created. You’ve probably noticed that they clutter your current directory by default. To change this setting, select the Files > Backup group. Look for the entry that says Backup Directory Alist. Click on the arrow, or move your point to the arrow and press <Enter>. Click on INS, or move your point to INS and press <Enter>. Fill it in as follows:

  • Regexp matching filename: .
  • Backup directory name: ~/.emacs.d/backups

Click on State and choose Save for future sessions. This will save your changes to ~/.emacs.d/init.el. When you’re done, type q to close the screen.

You can also jump straight to customizing a specific variable. For example, if you want to change the way Emacs handles case-sensitive search, you can use M-x customize-variable to set the case-fold-search variable. By default, case fold search is on, which means that searching for a lower-case “hello” will match an upper-case “HELLO” as well. If you would like to change this so that lowercase only matches lowercase and uppercase matches only uppercase, you can toggle this variable. I like leaving case fold search on because it’s more convenient for me. If you make lots of changes, you can use the Apply and Save button to save all the changes on your current screen.

Not sure what to customize? You can learn about options by browsing through M-x customize or reading the manual (Help > Read the Emacs Manual or M-x info-emacs-manual). You can also search for keywords using M-x customize-apropos.

~/.emacs.d/init.el

The Customize interface lets you change lots of options, but not everything can be changed through Customize. That’s where your Emacs configuration file comes in. This used to be a file called ~/.emacs in your home directory, and you’ll still come across lots of pages that refer to a .emacs file (or “dot emacs”). The new standard is to put configuration code in your ~/.emacs.d/init.el file, which you can create if it does not yet exist.

What goes into your ~/.emacs.d/init.el file? If you open it now, you’ll probably find the settings you saved using M-x customize. You can also call functions, set variables, and even override the way Emacs works. As you learn more about Emacs, you’ll probably find Emacs Lisp snippets on web pages and in manuals. For example, the Org manual includes the following lines:

(global-set-key "\C-cl" 'org-store-link)
(global-set-key "\C-cc" 'org-capture)
(global-set-key "\C-ca" 'org-agenda)
(global-set-key "\C-cb" 'org-iswitchb)

This code sets C-c l (that’s Control-c l) to run org-store-link, C-c c to run org-capture, C-c a to run org-agenda, and C-c b to run org-iswitchb. You can add those to the end of your ~/.emacs.d/init.el file. They’ll be loaded the next time you start Emacs. If you want to reload your ~/.emacs.d/init.el without restarting, use M-x eval-buffer.

Emacs Lisp may look strange. Don’t worry, you can get the hang of it even if you don’t think of yourself as a programmer. You can start by copying interesting snippets from other people’s configuration files. Start with small chunks instead of large ones, so you can test if things work the way you want them to. If you need help, StackOverflow and other Q&A resources may be useful.

As you experiment with configuring Emacs, you may run into mistakes or errors. You can find out whether it’s a problem with Emacs or with your configuration by loading Emacs with emacs -Q, which skips your configuration. If Emacs works fine with your configuration, check your ~/.emacs.d/init.el to see which code messed things up. You can comment out regions by selecting them and using M-x comment-region. That way, they won’t be evaluated when you start Emacs. You can uncomment them with M-x uncomment-region.

Emacs gets even awesomer when you tailor it to the way you want to work. Enjoy customizing it!
