#+title:    :lang org
#+subtitle: Organize your plain life in plain text
#+created:  February 20, 2017
#+since:    2.0.0

* Description :unfold:
This module adds org-mode support to Doom Emacs, along with a number of
adjustments, extensions and reasonable defaults to make it more performant and
intuitive out of the box:

- A custom, centralized attachment system that stores files in one place, rather
  than in the same directory as the input file(s) (only applies to attachments
  from files in/under var:org-directory).
- Executable code blocks with support for a variety of languages and tools
  (depending on what :lang modules are enabled).
- Supports an external org-capture workflow through the =bin/org-capture= shell
  script and fn:+org-capture/open-frame.
- A configuration for using org-mode for slide-show presentations or exporting
  org files to reveal.js slideshows.
- Drag-and-drop support for images (with inline preview) and media files (drops
  a file icon and a short link) (requires [[doom-module:+dragndrop]] flag).
- Integration with pandoc, ipython, jupyter, reveal.js, beamer, and others
  (requires flags).
- Export-to-clipboard functionality, for copying text into formatted html,
  markdown or rich text to the clipboard (see fn:+org/export-to-clipboard and
  fn:+org/export-to-clipboard-as-rich-text).

#+begin_quote
Org is a system for writing plain text notes with syntax highlighting, code
execution, task scheduling, agenda management, and many more. The whole idea is
that you can write notes and mix them with references to things like articles,
images, and example code combined with the output of that code after it is
executed.

** Hacks
- Adds support for a ~:sync~ parameter for org src blocks. This overrides
  ~:async~.
- Gracefully degrades ~:async~ babel blocks to ~:sync~ when [[doom-package:ob-async]] would cause
  errors or issues (such as with a ~:session~ parameter, which [[doom-package:ob-async]] does not
  support, or when exporting org documents).
- The window is recentered when following links.
- The breadcrumbs displayed in eldoc when hovering over an org headline has been
  reworked to strip out link syntax and normalize font-size disparities.
- If [[doom-module::ui workspaces]] is enabled, persp-mode won't register org agenda buffers
  that are temporarily opened in the background.
- Temporary org agenda files aren't added to recentf.
- =file:= links are highlighted with the [[face:error]] face if they are broken.
- TAB was changed to toggle only the visibility state of the current subtree,
  rather than cycle through it recursively. This can be reversed with:

  #+begin_src emacs-lisp
  (after! evil-org
    (remove-hook 'org-tab-first-hook #'+org-cycle-only-current-subtree-h))
  #+end_src
- (Evil users) Nearby tables are formatted when exiting insert or replace mode
  (see [[fn:+org-enable-auto-reformat-tables-h]]).
- Statistics cookies are updated when saving the buffer of exiting insert mode
  (see [[fn:+org-enable-auto-update-cookies-h]]).
- Org-protocol has been lazy loaded (see [[fn:+org-init-protocol-lazy-loader-h]]);
  loaded when the server receives a request for an =org-protocol://= url.
- Babel and babel plugins are now lazy loaded (see
  [[fn:+org-init-babel-lazy-loader-h]]); loaded when a src block is executed. No need
  to use [[var:org-babel-do-load-languages]] in your config, just install your babel
  packages to extend language support (and ensure its ~org-babel-execute:*~
  function is autoloaded).
- If a variable is used as a file path in [[var:org-capture-template]], it will be
  resolved relative to [[var:org-directory]], instead of [[var:default-directory]] (see
  [[fn:+org--capture-expand-variable-file-a]]).

* Installation
[[id:01cffea4-3329-45e2-a892-95a384ab2338][Enable this module in your ~doom!~ block.]]

This module has no hard requirements, but these soft requirements are needed to
use Org's more esoteric features:
- For inline LaTeX previews, [[doom-executable:latex]] and [[doom-executable:dvipng]] is needed.
- To render GNUPlot images (with [[doom-module:+gnuplot]] flag) the [[doom-executable:gnuplot]] program is needed.
- To execute babel code blocks, you need whatever dependencies those languages
  need. It is recommended you enable the associated [[doom-module::lang]] module and ensure its
  dependencies are met, e.g. install the [[doom-executable:ruby]] executable for ruby support. To
  use ~jupyter kernels~ you need the [[doom-module:+jupyter]] flag, the associated kernel as
  well as the [[doom-executable:jupyter]] program.
- [[doom-package:org-roam]] (with [[doom-module:+roam]] or [[doom-module:+roam2]] flag) requires [[doom-executable:sqlite3]] to be installed.

* TODO Usage
#+begin_quote
 󱌣 /This module's usage documentation is incomplete./ [[doom-contrib-module:][Complete it?]]
#+end_quote

** Invoking the org-capture frame from outside Emacs
The simplest way to use the org-capture frame is through the ~bin/org-capture~
script. I'd recommend binding a shortcut key to it. If Emacs isn't running, it
will spawn a temporary daemon for you.

Alternatively, you can call ~+org-capture/open-frame~ directly, e.g.
#+begin_src sh
emacsclient --eval '(+org-capture/open-frame INITIAL-INPUT KEY)'
#+end_src

** Built-in custom link types
This module defines a number of custom link types in ~+org-init-custom-links-h~.
They are (with examples):

- ~doom-docs:index.org~ -> =~/.emacs.d/docs/%s=
- ~doom-modules:editor/evil/README.org~ -> =~/.emacs.d/modules/%s=
- ~doom-repo:issues~ -> =https://github.com/hlissner/doom-emacs/%s=
- ~doom:core/core.el~ -> =~/.emacs.d/%s=
- ~duckduckgo:search terms~
- ~gimages:search terms~ (Google Images)
- ~github:hlissner/doom-emacs~
- ~gmap:Toronto, Ontario~ (Google Maps)
- ~google:search terms~
- ~kagi:search terms~
- ~org:todo.org~ -> ={org-directory}/%s=
- ~wolfram:sin(x^3)~
- ~wikipedia:Emacs~
- ~youtube:P196hEuA_Xc~ (link only)
- ~yt:P196hEuA_Xc~ (like =youtube=, but includes an inline preview of the video)

** evil-mode keybindings

#+begin_src emacs-lisp
;; in $DOOMDIR/config.el
(setq org-directory "~/new/org/location/")
#+end_src

** Changing ~org-noter-notes-search-path~

#+end_src

* Troubleshooting
[[doom-report:][Report an issue?]]

** =org-roam=
*** Should I go with =+roam= (v1) or =+roam2= (v2)?
Long story short: if you're new to [[doom-package:org-roam]] and haven't used it, then you should
go with [[doom-module:+roam2]]; if you already have an ~org-roam-directory~ with the v1 files in
it, then you can keep use [[doom-module:+roam]] for the time being, but it will eventually be
removed, so you should [[https://www.orgroam.com/manual.html#How-to-migrate-from-Org_002droam-v1_003f][migrate]] at your earliest convenience.

V1 isn't actively maintained anymore and is now basically EOL. This means that
the feature disparity between the both will continue to grow, while its existing
bugs and problems won't be addressed, at least by the main maintainers. V2 can
be considered as a complete rewrite of the package so it comes with a lot of
breaking changes.

To learn more about v2 you can use the next resources:
- [[https://github.com/org-roam/org-roam/blob/master/doc/org-roam.org][Org-roam v2 Official Manual]]
- [[https://github.com/org-roam/org-roam/wiki/Hitchhiker's-Rough-Guide-to-Org-roam-V2][Hitchhiker's Rough Guide to Org roam V2]]
- [[https://blog.jethro.dev/posts/org_roam_v2/][Releasing Org-roam v2 - Jethro Kuan's blog]]
- [[https://org-roam.discourse.group/t/org-roam-major-redesign/1198][Thread about the redesign from Org-Roam Discourse]]

*** Migrating your existing files from v1 (=+roam=) to v2 (=+roam2=)
V2 comes with a migration wizard for v1 users. It's new, which means issues can
appear during the migration process. Because of that, *don't forget to backup*
your ~org-roam-directory~ before attempting to migrate.

In order to migrate from v1 to v2 using Doom follow the next steps:
1. Enable [[doom-module:+roam2]] flag (and disable [[doom-module:+roam]] if it was previously enabled) in your
   =init.el=.
2. Ensure your ~org-roam-directory~ points to a directory with your v1 files.
3. Run ~$ doom sync -u~ in your shell.
4. Restart Emacs (if it was previously opened) and run ~org-roam-migrate-wizard~
   command (~M-x org-roam-migrate-wizard RET~). The wizard will automatically
   attempt to backup your previous ~org-roam-directory~ to =org-roam.bak=, but
   just in case backup it yourself too.
4. After the wizard is done you should be good to go. Verify the integrity of
   your data and whether it did everything as expected. In case of failure
   [[https://github.com/org-roam/org-roam/issues][report]] your issue.
