高效使用 Org-mode

简介

在我前篇关于 Emacs 的文章中我提到了 Org-mode，一个笔记管理工具和组织工具。文本，我将会描述一下我日常的 Org-mode 使用案例。

笔记和代办列表

首先而且最重要的是，Org-mode 是一个管理笔记和待办列表的工具，Org-mode 的所有工具都聚焦于使用纯文本文件记录笔记。我使用 Org-mode 管理多种笔记。

一般性笔记

Org-mode 最基本的应用场景就是以笔记的形式记录下你想记住的事情。比如，下面是我正在学习的笔记内容：

* Learn
** Emacs LISP
*** Plan

 - [ ] Read best practices
 - [ ] Finish reading Emacs Manual
 - [ ] Finish Exercism Exercises
 - [ ] Write a couple of simple plugins
 - Notification plugin

*** Resources

 [[http://batsov.com/articles/2011/11/30/the-ultimate-collection-of-emacs-resources/][The Ultimate Collection of Emacs Resources]]

** Rust gamedev
*** Study [[https://github.com/SergiusIW/gate][gate]] 2d game engine with web assembly support
*** [[ggez][https://github.com/ggez/ggez]]
*** [[https://www.amethyst.rs/blog/release-0-8/][Amethyst 0.8 Relesed]]

** Upgrade Elixir/Erlang Skills
*** Read Erlang in Anger

借助 org-bullets 它看起来是这样的：

在这个简单的例子中，你能看到 Org-mode 的一些功能：

笔记允许嵌套
链接
带复选框的列表

项目待办

我在工作时时常会发现一些能够改进或修复的事情。我并不会在代码文件中留下 TODO 注释 (坏味道)，相反我使用 org-projectile 来在另一个文件中记录一个 TODO 事项，并留下一个快捷方式。下面是一个该文件的例子：

* [[elisp:(org-projectile-open-project%20"mana")][mana]] [3/9]
 :PROPERTIES:
 :CATEGORY: mana
 :END:
** DONE [[file:~/Development/mana/apps/blockchain/lib/blockchain/contract/create_contract.ex::insufficient_gas_before_homestead%20=][fix this check using evm.configuration]]
 CLOSED: [2018-08-08 Ср 09:14]
 [[https://github.com/ethereum/EIPs/blob/master/EIPS/eip-2.md][eip2]]:
 If contract creation does not have enough gas to pay for the final gas fee for
 adding the contract code to the state, the contract creation fails (i.e. goes out-of-gas)
 rather than leaving an empty contract.
** DONE Upgrade Elixir to 1.7.
 CLOSED: [2018-08-08 Ср 09:14]
** TODO [#A] Difficulty tests
** TODO [#C] Upgrage to OTP 21
** DONE [#A] EIP150
 CLOSED: [2018-08-14 Вт 21:25]
*** DONE operation cost changes
 CLOSED: [2018-08-08 Ср 20:31]
*** DONE 1/64th for a call and create
 CLOSED: [2018-08-14 Вт 21:25]
** TODO [#C] Refactor interfaces
** TODO [#B] Caching for storage during execution
** TODO [#B] Removing old merkle trees
** TODO do not calculate cost twice
* [[elisp:(org-projectile-open-project%20".emacs.d")][.emacs.d]] [1/3]
 :PROPERTIES:
 :CATEGORY: .emacs.d
 :END:
** TODO fix flycheck issues (emacs config)
** TODO use-package for fetching dependencies
** DONE clean configuration
 CLOSED: [2018-08-26 Вс 11:48]

它看起来是这样的：

本例中你能看到更多的 Org mode 功能：

todo 列表具有 TODO，DONE 两个状态。你还可以定义自己的状态 (WAITING 等)
关闭的事项有 CLOSED 时间戳
有些事项有优先级 - A，B，C。
链接可以指向文件内部 ([[file:~/。..])

捕获模板

正如 Org-mode 的文档中所描述的，capture 可以在不怎么干扰你工作流的情况下让你快速存储笔记。

我配置了许多捕获模板，可以帮我快速记录想要记住的事情。

(setq org-capture-templates
'(("t" "Todo" entry (file+headline "~/Dropbox/org/todo.org" "Todo soon")
"* TODO %? \n %^t")
("i" "Idea" entry (file+headline "~/Dropbox/org/ideas.org" "Ideas")
"* %? \n %U")
("e" "Tweak" entry (file+headline "~/Dropbox/org/tweaks.org" "Tweaks")
"* %? \n %U")
("l" "Learn" entry (file+headline "~/Dropbox/org/learn.org" "Learn")
"* %? \n")
("w" "Work note" entry (file+headline "~/Dropbox/org/work.org" "Work")
"* %? \n")
("m" "Check movie" entry (file+headline "~/Dropbox/org/check.org" "Movies")
"* %? %^g")
("n" "Check book" entry (file+headline "~/Dropbox/org/check.org" "Books")
"* %^{book name} by %^{author} %^g")))

做书本记录时我需要记下它的名字和作者，做电影记录时我需要记下标签，等等。
