Emacs #2: Introducing org-mode
|
||||
======
|
||||
|
||||
In [my first post in my series on Emacs][1], I described returning to Emacs after over a decade of vim, and org-mode being the reason why.
|
||||
|
||||
I really am astounded at the usefulness, and simplicity, of org-mode. It is really a killer app.
|
||||
|
||||
**So what exactly is org-mode?**
|
||||
|
||||
I wrote yesterday:
|
||||
|
||||
> It’s an information organization platform. Its website says “Your life in plain text: Org mode is for keeping notes, maintaining TODO lists, planning projects, and authoring documents with a fast and effective plain-text system.”
|
||||
|
||||
That’s true, but doesn’t quite capture it. org-mode is a toolkit for you to organize things. It has reasonable out-of-the-box defaults, but it’s designed throughout for you to customize.
|
||||
|
||||
To highlight a few things:
|
||||
|
||||
* **Maintaining TODO lists** : items can be scattered across org-mode files, contain attachments, have tags, deadlines, schedules. There is a convenient “agenda” view to show you what needs to be done. Items can repeat.
|
||||
* **Authoring documents** : org-mode has special features for generating HTML, LaTeX, slides (with LaTeX beamer), and all sorts of other formats. It also supports direct evaluation of code in-buffer and literate programming in virtually any Emacs-supported language. If you want to bend your mind on this stuff, read [this article on literate devops][2]. The [entire Worg website][3]
|
||||
is made with org-mode.
|
||||
* **Keeping notes** : yep, it can do that too. With full-text search, cross-referencing by file (as a wiki), by UUID, and even into other systems (into mu4e by Message-ID, into ERC logs, etc, etc.)
|
||||
|
||||
|
||||
|
||||
**Getting started**
|
||||
|
||||
I highly recommend watching [Carsten Dominik’s excellent Google Talk on org-mode][4]. It is an excellent introduction.
|
||||
|
||||
org-mode is included with Emacs, but you’ll often want a more recent version. Debian users can `apt-get install org-mode`, or it comes with the Emacs packaging system; `M-x package-install RET org-mode RET` may do it for you.
|
||||
|
||||
Now, you’ll probably want to start with the org-mode compact guide’s [introduction section][5], noting in particular to set the keybindings mentioned in the [activation section][6].
|
||||
|
||||
**A good tutorial…**
|
||||
|
||||
I’ve linked to a number of excellent tutorials and introductory items; this post is not going to serve as a tutorial. There are two good videos linked at the end of this post, in particular.
|
||||
|
||||
**Some of my configuration**
|
||||
|
||||
I’ll document some of my configuration here, and go into a bit of what it does. This isn’t necessarily because you’ll want to copy all of this verbatim — but just to give you a bit of an idea of some of what can be configured, an idea of what to look up in the manual, and maybe a reference for “now how do I do that?”
|
||||
|
||||
First, I set up Emacs to work in UTF-8 by default.
|
||||
```
|
||||
(prefer-coding-system 'utf-8) (set-language-environment "UTF-8")
|
||||
```
|
||||
|
||||
org-mode can follow URLs. By default, it opens in Firefox, but I use Chromium.
|
||||
```
|
||||
(setq browse-url-browser-function 'browse-url-chromium)
|
||||
```
|
||||
|
||||
I set the basic key bindings as documented in the Guide, plus configure the M-RET behavior.
|
||||
|
||||
```
|
||||
(global-set-key "\C-cl" 'org-store-link)
|
||||
(global-set-key "\C-ca" 'org-agenda)
|
||||
(global-set-key "\C-cc" 'org-capture)
|
||||
(global-set-key "\C-cb" 'org-iswitchb)
|
||||
|
||||
(setq org-M-RET-may-split-line nil)
|
||||
```
|
||||
|
||||
|
||||
**Configuration: Capturing**
|
||||
|
||||
I can press `C-c c` from anywhere in Emacs. It will [capture something for me][7], and include a link back to whatever I was working on.
|
||||
|
||||
You can define [capture templates][8] to set how this will work. I am going to keep two journal files for general notes about meetings, phone calls, etc. One for personal, one for work items. If I press `C-c c j`, then it will capture a personal item. The %a in all of these includes the link to where I was (or a link I had stored with `C-c l`).
|
||||
|
||||
```
|
||||
(setq org-default-notes-file "~/org/tasks.org")
|
||||
(setq org-capture-templates
|
||||
'(
|
||||
("t" "Todo" entry (file+headline "inbox.org" "Tasks")
|
||||
"* TODO %?\n %i\n %u\n %a")
|
||||
("n" "Note/Data" entry (file+headline "inbox.org" "Notes/Data")
|
||||
"* %? \n %i\n %u\n %a")
|
||||
("j" "Journal" entry (file+datetree "~/org/journal.org")
|
||||
"* %?\nEntered on %U\n %i\n %a")
|
||||
("J" "Work-Journal" entry (file+datetree "~/org/wjournal.org")
|
||||
"* %?\nEntered on %U\n %i\n %a")
|
||||
))
|
||||
(setq org-irc-link-to-logs t)
|
||||
```
|
||||
|
||||
I like to link by UUIDs, which lets me move things between files without breaking locations. This helps generate UUIDs when I ask Org to store a link target for future insertion.
|
||||
|
||||
```
|
||||
(require 'org-id)
|
||||
(setq org-id-link-to-org-use-id 'create-if-interactive)
|
||||
```
|
||||
|
||||
**Configuration: agenda views**
|
||||
|
||||
I like my week to start on a Sunday, and for org to note the time when I mark something as done.
|
||||
|
||||
```
|
||||
(setq org-log-done 'time)
|
||||
(setq org-agenda-start-on-weekday 0)
|
||||
```
|
||||
|
||||
**Configuration: files and refiling**
|
||||
|
||||
Here I tell it what files to use in the agenda, and to add a few more to the plain text search. I like to keep a general inbox (from which I can move, or “refile”, content), and then separate tasks, journal, and knowledge base for personal and work items.
|
||||
|
||||
```
|
||||
(setq org-agenda-files (list "~/org/inbox.org"
|
||||
"~/org/email.org"
|
||||
"~/org/tasks.org"
|
||||
"~/org/wtasks.org"
|
||||
"~/org/journal.org"
|
||||
"~/org/wjournal.org"
|
||||
"~/org/kb.org"
|
||||
"~/org/wkb.org"
|
||||
))
|
||||
(setq org-agenda-text-search-extra-files
|
||||
(list "~/org/someday.org"
|
||||
"~/org/config.org"
|
||||
))
|
||||
|
||||
(setq org-refile-targets '((nil :maxlevel . 2)
|
||||
(org-agenda-files :maxlevel . 2)
|
||||
("~/org/someday.org" :maxlevel . 2)
|
||||
("~/org/templates.org" :maxlevel . 2)
|
||||
)
|
||||
)
|
||||
(setq org-outline-path-complete-in-steps nil) ; Refile in a single go
|
||||
(setq org-refile-use-outline-path 'file)
|
||||
```
|
||||
|
||||
**Configuration: Appearance**
|
||||
|
||||
I like a pretty screen. After you’ve gotten used to org a bit, you might try this.
|
||||
|
||||
```
|
||||
(require 'org-bullets)
|
||||
(add-hook 'org-mode-hook
|
||||
(lambda ()
|
||||
(org-bullets-mode t)))
|
||||
(setq org-ellipsis "⤵")
|
||||
```
|
||||
|
||||
**Coming up next…**
|
||||
|
||||
This hopefully showed a few things that org-mode can do. Coming up next, I’ll cover how to customize TODO keywords and tags, archiving old tasks, forwarding emails to org-mode, and using git to synchronize between machines.
