(feat): Hide drawer content when capturing

`string-blank-p` returns a non-nil value if the string is blank, and
nil (which you can't compare to 0) otherwise.

+- [#1252](https://github.com/org-roam/org-roam/issues/1252) respect original link type during automatic replacement
+
+## 1.2.2 (06-10-2020)
+
+In this release we support fuzzy links of the form `[[roam:Title]]`, `[[roam:*Headline]]` and `[[roam:Title*Headline]]`. Completion for these fuzzy links is supported via `completion-at-point`.
+
+Org-roam now does not resolve symlinks. This significantly speeds up cache builds, but may result in some workflows breaking. In particular, Org-roam now cannot figure out if two distinct file paths in the Org-roam directory are the same file, and both files will be processed as if they were different files. This error seems to be unavoidable now that symlinks are not resolved, but this workflow is rare and should not affect most users.
+
+This change requires you to set `org-roam-directory` to the resolved path of a folder. That is:
+
+```elisp
+(setq org-roam-directory (file-truename "/path/to/directory/"))
+```
+
+### Breaking Changes
+
+- [#1164](https://github.com/org-roam/org-roam/pull/1164) Org-roam now stores the database in the user's Emacs directory by default
+- [#910](https://github.com/org-roam/org-roam/pull/910) Deprecate `company-org-roam`, using `completion-at-point` instead. To use this with company, add the `company-capf` backend instead.
+- [#1109](https://github.com/org-roam/org-roam/pull/1109) Org-roam now does not resolve symlinks.
+
+### Features

+- [#1079](https://github.com/org-roam/org-roam/pull/1079) Add `org-roam-tag-face` to customize appearance of tags in interactive commands
+- [#1073](https://github.com/org-roam/org-roam/pull/1073) Rename file on title change, when `org-roam-rename-file-on-title-change` is non-nil.
+- [#1071](https://github.com/org-roam/org-roam/pull/1071) Update link descriptions on title changes, and clean-up rename file advice

+
+### Bugfixes
+
+- [#1057](https://github.com/org-roam/org-roam/pull/1057) Improve performance of database builds by preventing generation of LaTeX and image previews.
+- [#1103](https://github.com/org-roam/org-roam/pull/1103) Fix long build-times for Windows on files with URL links
+
+## 1.2.1 (27-07-2020)
+
+This release consisted of a big deal of refactoring and bug fixes. Notably, we fixed several catastrophic failures on db builds with bad setups (#854), and modularized tag and title extractions.
+
+We also added some new features that had been a long time coming:
+
+1. We made the backlinks more outline-friendly by also showing the outline hierarchy for a backlink (#863)
+2. We now support nested captures, which is crucial for `org-roam-protocol` (#966)
+
+### Breaking Changes
+
+- [#908](https://github.com/org-roam/org-roam/pull/908) Normalized titles in database. May break external packages that rely on unnormalized titles.
+
+### Features
+
+- [#814](https://github.com/org-roam/org-roam/pull/814) Implement `org-roam-insert-immediate`

+- [#847](https://github.com/org-roam/org-roam/pull/847) Use sqlite3 transactions instead of storing the values to be inserted.
+- [#851](https://github.com/org-roam/org-roam/pull/851) Add `'first-directory'` option for `org-roam-tag-sources`
+- [#863](https://github.com/org-roam/org-roam/pull/863) Display outline hierarchy in backlinks buffer
+- [#898](https://github.com/org-roam/org-roam/pull/898) Add `org-roam-random-note` to browse a random note.
+- [#900](https://github.com/org-roam/org-roam/pull/900) Support and index all valid org links
+- [#966](https://github.com/org-roam/org-roam/pull/966) Enable nested captures
+
+### Bugfixes
+
+- [#854](https://github.com/org-roam/org-roam/pull/854) Warn instead of fail when duplicate refs and IDs exist.
+- [#857](https://github.com/org-roam/org-roam/pull/857) Fix tag extraction for symlinked directories.
+- [#894](https://github.com/org-roam/org-roam/pull/894) Perform link fixes on all Org-roam files
+- [#952](https://github.com/org-roam/org-roam/pull/952) Cache `${foo}` template variables so they do not need to be re-entered twice
+
+## 1.2.0 (12-06-2020)
+
+In this release, we improved the linking process by achieving feature parity between links to files and links to headlines. Before, we used the `file:foo::*bar` format to link to the headline `bar` in file `foo`, but this was prone to breakage upon renaming the file or modifying the headline. This is not the case anymore. Now, we use `org-id` to create IDs for those headlines, which are then stored in our database to compute the relationships and jump around. Note that this will work even if you’re not using `org-id` in your global configuration for Org-mode.
+
+This is a major step forward. Supporting the in-file structure of Org-mode files means that we can interface with many of its core-features like TODOs, properties, priorities, etc. UX will have to be figured out, but this release ushers in a new age in terms of functionalities.
+
+We also add `org-roam-unlinked-references`, which naively finds text that could be references to the current Org-roam file.
+
+### Breaking Changes
+
+- [#701](https://github.com/org-roam/org-roam/pull/701) Use `emacsql-sqlite3` instead of `emacsql-sqlite` for better Windows compatibility. This requires the presence of the standard `sqlite3` binary on your machine.
+- [#750](https://github.com/org-roam/org-roam/pull/750) Deprecate `org-roam-buffer-no-delete-other-windows` in favour of `org-roam-buffer-window-parameters`.
+
+### Features
+
+- [#787](https://github.com/org-roam/org-roam/pull/787) Add `org-roam-unlinked-references`
+- [#783](https://github.com/org-roam/org-roam/pull/783) Add support for headlines
+- [#757](https://github.com/org-roam/org-roam/pull/757) Roam global properties are now case-insensitive
+- [#680](https://github.com/org-roam/org-roam/pull/680) , [#703](https://github.com/org-roam/org-roam/pull/703), [#708](https://github.com/org-roam/org-roam/pull/708) Add `org-roam-doctor` checkers for `ROAM_*` properties
+- [#664](https://github.com/org-roam/org-roam/pull/664) Add support for shelling out to `rg` and `find` in `org-roam--list-files`
+- [#679](https://github.com/org-roam/org-roam/pull/679), [#683](https://github.com/org-roam/org-roam/pull/683) Building of the graph now happens in a separate process
+
+### Bugfixes
+
+- [#714](https://github.com/org-roam/org-roam/pull/714) No longer print citelinks in backlinks buffer if there is no `ROAM_KEY` property or `org-ref` is not installed
+- [#759](https://github.com/org-roam/org-roam/pull/759), [#760](https://github.com/org-roam/org-roam/pull/760) Tags are only added to the tags table if there are actually tags present
+- [#700](https://github.com/org-roam/org-roam/pull/700), [#733](https://github.com/org-roam/org-roam/pull/733) Allow symlinks within the `org-roam` directory
+
+## 1.1.1 (18-05-2020)
+
+In this release, we added two new features:
+
+1. `org-roam-doctor`: a linting system that helps you discover possible problems with your Org-roam files. This is in the spirit of keeping notes in top quality.
+2. A tagging system: one can now use sub-directories, and the `#+roam_tags` key add additional meta data to notes. For more information, see [here](https://www.orgroam.com/manual/Tags.html#Tags).
+
+As usual, this release comes with a multitude of bug-fixes and refactorings.
+
+### Breaking Changes

+- [#523](https://github.com/org-roam/org-roam/pull/523) remove `org-roam-completion-fuzzy-match` in favor of using completion mechanism's configuration options directly
+- [#547](https://github.com/org-roam/org-roam/pull/547) Deprecate `org-roam-db--maybe-update`, in favour of `org-roam-db--update-maybe`

-## Synopsis
+<img src="https://www.orgroam.com/img/logo.svg" align="right" alt="Org-roam Logo" width="240">
 
-Org-roam is a [Roam][roamresearch] replica built on top of the
-all-powerful [Org-mode][org].
+Org-roam is a plain-text knowledge management system. It brings some of
+[Roam's][roamresearch] more powerful features into the [Org-mode][org]
+ecosystem.
 
-Org-roam is a solution for effortless non-hierarchical note-taking
-with Org-mode. With Org-roam, notes flow naturally, making note-taking
-fun and easy. Org-roam should also work as a plug-and-play solution
-for anyone already using Org-mode for their personal wiki.
+Org-roam borrows principles from the Zettelkasten method, providing a solution
+for non-hierarchical note-taking. It should also work as a plug-and-play
+solution for anyone already using Org-mode for their personal wiki.
 
-Org-roam aims to implement the core features of Roam, leveraging the
-mature ecosystem around Org-mode where possible. Eventually, we hope
-to further introduce features enabled by the Emacs ecosystem.
+- **Private and Secure**: Edit your personal wiki completely offline, entirely
+  in your control. Encrypt your notes with GPG. Take lasting notes in
+  plain-text.
+- **Networked Thought**: Connect notes and thoughts together with ease using
+  backlinks. Discover surprising and previously unseen connections in your notes
+  with the built-in graph visualization.
+- **Extensible and Powerful**: Leverage Emacs' fantastic text-editing interface,
+  and the mature Emacs and Org-mode ecosystem of packages.
+- **Free and Open Source**: Org-roam is licensed under the GNU General Public
+  License version 3 or later.

-## A Preview
-
-Here's a screenshot of `org-roam`. The `org-roam` buffer shows
-backlinks for the active org buffer in the left window, as well as the
-surrounding content in the backlink file. The database is built once,
-and updated incrementally. The graph is generated from the link
-structure, and can be used to navigate to the respective files.

-For more detailed installation and configuration instructions (including for
-Doom and Spacemacs users), please see [the
-documentation](https://org-roam.readthedocs.io/en/master/installation/).
+The `file-truename` function is only necessary when you use symbolic links
+inside `org-roam-directory`: Org-roam does not resolve symbolic links.
+
+Org-roam requires sqlite to function. Org-roam optionally uses Graphviz for
+graph-related functionality. It is recommended to install PCRE-enabled ripgrep
+for better performance and extended functionality.

-The bulk of Org-roam's functionality is built on top of vanilla
-Org-mode. However, to support additional functionality, Org-roam adds
-several Org-roam-specific keywords. These functionality are not
-crucial to effective use of Org-roam.
-
-## File Aliases
-
-Suppose you want a note to be referred to by different names (e.g.
-"World War 2", "WWII"). You may specify such aliases using the
-`#+ROAM_ALIAS` attribute:
-
-```org
-#+TITLE: World War 2
-#+ROAM_ALIAS: "WWII" "World War II"
-```
-
-
-## File Refs
-
-Refs are unique identifiers for files. Each note can only have 1 ref.
-For example, a note for a website may contain a ref:
-
-```org
-#+TITLE: Google
-#+ROAM_KEY: https://www.google.com/
-```
-
-These keys come in useful for when taking website notes, using the
-`roam-ref` protocol (see [Roam Protocol](roam_protocol.md)).
-
-Alternatively, add a ref for notes for a specific paper, using its
-[org-ref](https://github.com/jkitchin/org-ref) citation key:
-
-```org
-#+TITLE: Neural Ordinary Differential Equations
-#+ROAM_KEY: cite:chen18_neural_ordin_differ_equat
-```
-
-The backlinks buffer will show any cites of this key: e.g.

-The number of configuration options is deliberately kept small, to
-keep the Org-roam codebase manageable. However, we attempt to
-accommodate as many usage styles as possible.
-
-All of Org-roam's customization options can be viewed via `M-x
-customize-group org-roam`.
-
-## Setting the Org-roam Directory
-
-Set `org-roam-directory` to the folder containing all your Org files:
-
-```emacs-lisp
-(setq org-roam-directory "/path/to/org/")
-```
-
-Every Org file, at any level of nesting, within `/path/to/org/` is
-considered part of the Org-roam ecosystem.
-
-### Having More Than One Org-roam Directory
-
-Emacs supports directory-local variables, allowing the value of
-`org-roam-directory` to be different in different directories. It does
-this by checking for a file named `.dir-locals.el`. 
-
-To add support for multiple directories, override the
-`org-roam-directory` variable using directory-local variables. This is
-what `.dir-locals.el` may contain:
-
-```emacs-lisp
-((nil . ((org-roam-directory . "/path/to/here/"))))
-```
-
-All files within that directory will be treated as their own separate
-set of Org-roam files. Remember to run `org-roam-db-build-cache` from a
-file within that directory, at least once.
-
-## Org-roam Buffer
-
-The Org-roam buffer defaults to popping up from the right. You may
-choose to set it to pop up from the left with `(setq
-org-roam-buffer-position 'left)`.
-
-The Org-roam buffer name can also be renamed: e.g. `(setq
-org-roam-buffer "*my-buffer-name*")`.
-
-The Org-roam buffer width is adjustable via `org-roam-buffer-width`.
-The value of `org-roam-buffer-width` set as a percentage of the total
-frame width. For example:
-
-```emacs-lisp
-(setq org-roam-buffer-width 0.4)
-```
-
-Will result in the Org-roam buffer taking up 40% of the screen width.
-
-You can change backlinks appearance in the buffer by customizing
-`org-roam-backlink` face (`M-x customize-face org-roam-backlink`).
-
-## Org-roam Links
-
-By default, links are inserted with the title as the link description.
-This can make them hard to distinguish from external links. You may
-choose add special indicators for Org-roam links by tweaking
-`org-roam-link-title-format`, for example:
-
-```emacs-lisp
-(setq org-roam-link-title-format "R:%s")
-```
-
-If your version of Org is at least `9.2`, you may also choose to
-simply style the link differently, by customizing `org-roam-link` face
-(`M-x customize-face org-roam-link`).
-
-## Org-roam Files
-
-Org-roam files are created and prefilled using Org-roam's templating
-system. The templating system is customizable, and the system is
-described in detail in the [Org-roam Template](templating.md) page.
-
-### Encryption
-
-Encryption (via GPG) can be enabled for all new files by setting
-`org-roam-encrypt-files` to `t`. When enabled, new files are created
-with the `.org.gpg` extension and decryption are handled automatically
-by EasyPG. 
-
-Note that Emacs will prompt for a password for encrypted files during
-cache updates if it requires reading the encrypted file. To reduce the
-number of password prompts, you may wish to cache the password.
-
-## Org-roam Graph Viewer
-
-Org-roam generates an SVG image using
-[Graphviz](https://graphviz.org/). To setup graph navigation, see the
-[Graph Setup](graph_setup.md) page.
-
-Org-roam tries its best to locate the Graphviz executable from your
-`PATH`, but if it fails to do so, you may set it manually:
-
-```
-(setq org-roam-graph-executable "/path/to/dot")
-```
-
-You may also choose to use `neato` in place of `dot`, which generates a more compact graph layout.
-
-```
-(setq org-roam-graph-executable "/path/to/neato")
-(setq org-roam-graph-extra-config '(("overlap" . "false")))
-```
-
-Org-roam also attempts to use Firefox (located on `PATH`) to view the
-SVG, you may choose to set it to any compatible program:
-
-```
-(setq org-roam-graph-viewer "/path/to/image-viewer")
-```
-
-### Excluding Nodes and Edges
-One may want to exclude certain files to declutter the graph. You can do so by setting `org-roam-graph-exclude-matcher`.
-
-```
-(setq org-roam-graph-exclude-matcher '("private" "dailies"))
-```
-
-This setting excludes all files whose path contain "private" or "dailies".
-
-## Org-roam Completion System
-
-Org-roam offers completion when choosing note titles etc.
-The completion system is configurable. The default setting,
-
-```
-(setq org-roam-completion-system 'default)
-```
-
-uses Emacs' standard `completing-read`. If you prefer [Helm](https://emacs-helm.github.io/helm/), use
-
-```
-(setq org-roam-completion-system 'helm)
-```
-
-Other options included `'ido`, and `'ivy'`.

-A number of packages work well combined with Org-Roam:
-
-## Deft
-
-[Deft][deft] provides a nice interface for browsing and filtering
-org-roam notes.
-
-```emacs-lisp
-(use-package deft
-  :after org
-  :bind
-  ("C-c n d" . deft)
-  :custom
-  (deft-recursive t)
-  (deft-use-filter-string-for-filename t)
-  (deft-default-extension "org")
-  (deft-directory "/path/to/org-roam-files/"))
-```
-
-If the title of the Org file is not the first line, you might not get
-nice titles. You may choose to patch this to use `org-roam`'s
-functionality. Here I'm using [el-patch](https://github.com/raxod502/el-patch):
-
-```emacs-lisp
-(use-package el-patch
-  :straight (:host github
-                   :repo "raxod502/el-patch"
-                   :branch "develop"))
-
-(eval-when-compile
-  (require 'el-patch))
-
-(use-package deft
-  ;; same as above...
-  :config/el-patch
-  (defun deft-parse-title (file contents)
-    "Parse the given FILE and CONTENTS and determine the title.
-If `deft-use-filename-as-title' is nil, the title is taken to
-be the first non-empty line of the FILE.  Else the base name of the FILE is
-used as title."
-    (el-patch-swap (if deft-use-filename-as-title
-                       (deft-base-filename file)
-                     (let ((begin (string-match "^.+$" contents)))
-                       (if begin
-                           (funcall deft-parse-title-function
-                                    (substring contents begin (match-end 0))))))
-                   (org-roam--get-title-or-slug file))))
-```
-
-The Deft interface can slow down quickly when the number of files get
-huge. [Notdeft][notdeft] is a fork of Deft that uses an external
-search engine and indexer.
-
-## Org-journal
-
-[Org-journal](https://github.com/bastibe/org-journal) is a more powerful
-alternative to the simple function `org-roam-dailies-today`. It provides better
-journaling capabilities, and a nice calendar interface to see all dated entries.
-
-```emacs-lisp
-(use-package org-journal
-  :bind
-  ("C-c n j" . org-journal-new-entry)
-  :custom
-  (org-journal-date-prefix "#+TITLE: ")
-  (org-journal-file-format "%Y-%m-%d.org")
-  (org-journal-dir "/path/to/org-roam-files/")
-  (org-journal-date-format "%A, %d %B %Y"))
-```
-
-## Note-taking Add-ons
-
-These are some plugins that make note-taking in Org-mode more
-enjoyable.
-
-### Org-download
-
-[Org-download][org-download] lets you screenshot and yank images from
-the web into your notes:
-
-![org-download](images/org-download.gif)
-
-```emacs-lisp
-(use-package org-download
-  :after org
-  :bind
-  (:map org-mode-map
-        (("s-Y" . org-download-screenshot)
-         ("s-y" . org-download-yank))))
-```
-
-### mathpix.el
-
-[mathpix.el][mathpix-el] uses [Mathpix's](https://mathpix.com/) API to convert clips into
-latex equations:
-
-![mathpix](images/mathpix.gif)
-
-```emacs-lisp
-(use-package mathpix.el
-  :straight (:host github :repo "jethrokuan/mathpix.el")
-  :custom ((mathpix-app-id "app-id")
-           (mathpix-app-key "app-key"))
-  :bind
-  ("C-x m" . mathpix-screenshot))
-```
-
-### Org-noter / Interleave
-
-[Org-noter][org-noter] and [Interleave][interleave] are both projects
-that allow synchronised annotation of documents (PDF, EPUB etc.)
-within Org-mode.
-
-### Org-ref
-
-[Org-ref][org-ref] does citation and bibliography management in
-Org-mode, and a great tool for scientific notes.
-
-### Spaced Repetition
-
-[Org-fc][org-fc] is a spaced repetition system that scales well with a
-large number of files. Other alternatives include
-[org-drill][org-drill], and [pamparam][pamparam].

-## What is Org-roam?
-
-Org-roam is a [Roam][roamresearch] replica built around the
-all-powerful [Org-mode][org].
-
-Org-roam is a solution for effortless non-hierarchical note-taking
-with Org-mode. With Org-roam, notes flow naturally, making note-taking
-fun and easy. Org-roam should also work as a plug-and-play solution
-for anyone already using Org-mode for their personal wiki.
-
-To understand more about Roam, a collection of links are available in
-[the appendix](notetaking_workflow.md).
-
-Org-roam aims to implement the core features of Roam, leveraging the
-mature ecosystem around Org-mode where possible. Eventually, we hope
-to further introduce features enabled by the Emacs ecosystem.
-
-## Why use Org-roam?
-
-##### Private and Secure
-
-Edit your personal wiki completely offline, entirely in your control.
-Encrypt your notes with GPG.
-
-##### Longevity
-
-Unlike web solutions like Roam research, the notes are first and
-foremost plain Org-mode files -- Org-roam simply builds up an
-auxilliary database to give the personal wiki superpowers. Having your
-notes in plain-text is crucial for the longevity of your wiki. Never
-have to worry about proprietary web solutions being taken down. Edit
-your plain-text notes in notepad if all other editors cease to exist.
-
-##### Free and Open-source
-
-Org-roam is free and open-source, which means that if you feel unhappy
-with any part of Org-roam, you may choose to extend Org-roam, or open
-a PR.
-
-##### Leverage the Org-mode Ecosystem
-
-Over the years, Emacs and Org-mode has developed into a mature system
-for plain-text organization. Building upon Org-mode already puts
-Org-roam light-years ahead of many other solutions.
-
-Emacs is also a fantastic interface for editing text, and we can
-inherit many of the powerful text-navigation and editing packages
-available to Emacs.
-
-There are several packages that are similar to Org-roam, see the
-[Comparison](comparison.md) page for a detailed comparison.
-
-## Project Status
-
-As of March 2020, most of the core functionality and interfaces have
-stabilized, and a stable release is near.

-## Basic Install and Configuration
-
-Org-roam is now available on MELPA, so you can install it via the following
-command:
-
-```
-M-x package-install RET org-roam RET
-```
-
-Alternatively, you may use package managers such as [straight][straight] or
-[quelpa][quelpa] to install the package.
-
-The recommended method of configuration is to use [use-package][use-package].
-
-```emacs-lisp
-(use-package org-roam
-      :hook
-      (after-init . org-roam-mode)
-      :custom
-      (org-roam-directory "/path/to/org-files/")
-      :bind (:map org-roam-mode-map
-              (("C-c n l" . org-roam)
-               ("C-c n f" . org-roam-find-file)
-               ("C-c n b" . org-roam-switch-to-buffer)
-               ("C-c n g" . org-roam-graph))
-              :map org-mode-map
-              (("C-c n i" . org-roam-insert))))
-```
-
-Or without `use-package`:
-
-```emacs-lisp
-(require 'org-roam)
-(define-key org-roam-mode-map (kbd "C-c n l") #'org-roam)
-(define-key org-roam-mode-map (kbd "C-c n f") #'org-roam-find-file)
-(define-key org-roam-mode-map (kbd "C-c n b") #'org-roam-switch-to-buffer)
-(define-key org-roam-mode-map (kbd "C-c n g") #'org-roam-graph)
-(define-key org-mode-map (kbd "C-c n i") #'org-roam-insert)
-(org-roam-mode +1)
-```
-
-The [Configuration](configuration.md) page details some of the common
-configuration options available.
-
-### Completion
-
-Link auto-completion is offered via
-[company-org-roam](https://github.com/jethrokuan/company-org-roam/), refer to
-the documentation there for further details.
-
-## Spacemacs
-
-If you are using Spacemacs, install org-roam by creating a simple layer that
-wraps Org-roam. Paste the following into a new file

-
-Next, append `org-roam` to the `dotspacemacs-configuration-layers`
-list in your `.spacemacs` configuration file. Reload (`SPC f e R`) or
-restart Emacs to load `org-roam`. It's functions are available under
-the prefix `SPC a r` and `, r` when visiting an org-mode buffer.
-
-If you also have the ranger layer installed, the prefix 'ar' conflict
-with that of the ranger layer. You might want to change it to 'aor'
-(also change the 'ar' to 'aor' in the other key-binding declarations)

-## Doom Emacs
-
-[Doom Emacs][doom] has a `+roam` flag on its `org` module for easy
-installation and configuration. Simply add the flag to the `org` section
-of your `~/.doom.d/init.el` and run `~/.emacs.d/bin/doom sync`.

-
-## Windows
-
-On Windows, if you follow the installation instructions above, you will likely get the error message: **"No EmacSQL SQLite binary available, aborting"**, and `org-roam` won't start properly.
-
-You need to do some additional steps to get `org-roam` to work.
-
-Essentially, you will need to have a binary file for `emacsql-sqlite` so that your Emacs can work with `sqlite` database -- `org-roam` uses it to track backlinks. The following options have been reported to work by Windows users in the community.
-
-Option 1. **Windows Subsystem for Linux (WSL)**
-: This option lets you use Linux on your Windows machine. It's Linux, so you don't need to do anything specific for Windows.
-
-Option 2. **mingw-x64**
-: Use mingw-x64. You would spend a bit of time to download it, and get familiar with how it works. You should be able to use Linux tools within your Windows [more contribution welcome].
-
-Option 3. **scoop**
-: Use [scoop](https://scoop.sh/) to install a couple of software tools (make and gcc) and manually compile a binary (`.exe`) file yourself. Find a short step-by-step guide below.
-
-Option 4. **emacsql-sqlite3**
-: Use another Emacs package called [`emacsql-sqlite3`](https://github.com/cireu/emacsql-sqlite3). You can download an [official binary](https://sqlite.org/download.html) for `sqlite3`. `emacsql-sqlite3` lets you use it. For this option to work, you need to adjust the `org-roam` source code, and get your modified version to work in your Emacs environment. Find a suggestion below.
-
-### scoop
-**Step 1.** In PowerShell, install `scoop` ([instruction here](https://scoop.sh/)).
-
-```powershell
-iwr -useb get.scoop.sh | iex
-```
-
-**Step 2.** In PowerShell, install `make` and `gcc` via scoop
-
-```powershell
-scoop install make gcc
-```
-
-**Step 3.** In Emacs, install the `emacsql-sqlite` package for your Emacs if it is not done yet.
-
-**Step 4.** In PowerShell, move to the directory where `emacsql.c` is stored.
-
-With MELPA, it is likely to be under your ELPA folder:
-
-```
-~\AppData\Roaming\.emacs.d\elpa\emacsql-sqlite-20190727.1710\sqlite
-```
-
-With Doom Emacs, it should be under your `.emacs\.local`:
-
-```
-~\.emacs.d\.local\straight\build\emacsql-sqlite\sqlite
-```
-
-Check the files via `dir` command. You should see these files:
-
-```powershell
-Mode                LastWriteTime         Length Name
-----                -------------         ------ ----
--a----       22/03/2020  12:10 PM           5170 emacsql.c
--a----       22/03/2020  12:10 PM            439 Makefile
--a----       22/03/2020  12:10 PM        7516138 sqlite3.c
--a----       22/03/2020  12:10 PM         526684 sqlite3.h
-```
-
-**Step 5.** Compile the `.exe` file with `make`
-
-```powershell
-make emacsql-sqlite CC=gcc LDLIBS=
-```
-
-You will see the process triggered with lots of text automatically scrolling down; it may take a couple of minutes for compilation to finish.
-
-Once compilation is done, check that `emacsql-sqlite.exe` has been added to the directory.
-
-**Step 6.** Relaunch Emacs, use `org-roam`
-
-When you start `org-roam` (e.g. via `org-roam-mode`), now you should no longer see the "No EmacSQL SQLite binary available, aborting" error. You are good to go.
-
-
-### emacsql-sqlite3
-
-1. In Emacs, install the `emacsql-sqlite3` package
-
-2. Using your text editor, etc. modify `org-roam-db.el`:
-
-    1. Replace `(require 'emacsql-sqlite)` with `(require 'emacsql-sqlite3)`
-
-    2. Comment/deactivate the complete `(defconst org-roam-db--sqlite-available-p ... )`
-
-    3. In `(defun org-roam-db ...`, replace `emacsql-sqlite`
-with `emacsql-sqlite3`
-
-3. If you compile `.el` files, ensure to replace `org-roam-db.elc` with the new source you modified.

-While exporting your documents to another format such as HTML -- whether using Org's in-built export or ox-hugo -- you can add a backlinks section which would display the backlinks to the current file. This is done via org-export's preprocessing hooks. See more at [Advanced Export Configuration (The Org Manual)](https://orgmode.org/manual/Advanced-Export-Configuration.html#Advanced-Export-Configuration).
-
-Following are two different configs that might be suitable for different use-cases. Add one of these snippets in your Emacs init file.
-
-### Only Backlinks
-
-This will display only the backlinks and not the contents.
-
-```emacs-lisp

-## What is Roam protocol?
-
-Org-roam extending `org-protocol` with 2 protocols: the `roam-file`
-and `roam-ref` protocol.
-
-## The `roam-file` protocol
-
-This is a simple protocol that opens the path specified by the `file`
-key (e.g. `org-protocol://roam-file?file=/tmp/file.org`). This is used
-in the generated graph.
-
-## The `roam-ref` Protocol
-
-This protocol finds or creates a new note with a given `ROAM_KEY` (see
-[Anatomy](anatomy.md)):
-
-![roam-ref](images/roam-ref.gif)
-
-To use this, create a Firefox bookmarklet as follows:
-
-```javascript
-javascript:location.href =
-'org-protocol:/roam-ref?template=r&ref='
-+ encodeURIComponent(location.href)
-+ '&title='
-+ encodeURIComponent(document.title)
-```
-
-where `template` is the template key for a template in
-`org-roam-capture-ref-templates`. More documentation on the templating
-system can be found [here](templating.md).
-
-These templates should contain a `#+ROAM_KEY: ${ref}` in it.
-
-## Setting up Org-roam protocol
-
-To enable org-roam's protocol extensions, you have to add the
-following to your init file:
-
-```emacs-lisp
-(require 'org-roam-protocol)
-```
-
-The instructions for setting up `org-protocol` can be found
-[here][org-protocol-inst], but they are reproduced below.
-
-We will also need to create a desktop application for `emacsclient`.
-The instructions for various platforms are shown below:
-
-## Linux
-
-Create a desktop application. I place mine in
-`~/.local/share/applications/org-protocol.desktop`:
-
-```
-[Desktop Entry]
-Name=Org-Protocol
-Exec=emacsclient %u
-Icon=emacs-icon
-Type=Application
-Terminal=false
-MimeType=x-scheme-handler/org-protocol
-```
-
-Associate `org-protocol://` links with the desktop application by
-running in your shell:
-
-```bash
-xdg-mime default org-protocol.desktop x-scheme-handler/org-protocol
-```
-
-To disable the "confirm" prompt in Chrome, you can also make Chrome
-show a checkbox to tick, so that the `Org-Protocol Client` app will be used
-without confirmation. To do this, run in a shell:
-
-```sh
-sudo mkdir -p /etc/opt/chrome/policies/managed/
-sudo tee /etc/opt/chrome/policies/managed/external_protocol_dialog.json >/dev/null <<'EOF'
-{
-  "ExternalProtocolDialogShowAlwaysOpenCheckbox": true
-}
-EOF
-sudo chmod 644 /etc/opt/chrome/policies/managed/external_protocol_dialog.json
-```
-
-and then restart Chrome (for example, by navigating to <chrome://restart>) to
-make the new policy take effect.
-
-See [here](https://www.chromium.org/administrators/linux-quick-start)
-for more info on the `/etc/opt/chrome/policies/managed` directory and
-[here](https://cloud.google.com/docs/chrome-enterprise/policies/?policy=ExternalProtocolDialogShowAlwaysOpenCheckbox)
-for information on the `ExternalProtocolDialogShowAlwaysOpenCheckbox`
-policy.
-
-
-## Mac OS
-
-One solution is to use
-[Platypus](https://github.com/sveinbjornt/Platypus). Here are the
-instructions for setting up with Platypus and Chrome:
-
-1. Install and launch Platypus (with [Homebrew](https://brew.sh/)):
-
-```sh
-brew cask install platypus
-```
-2. Create a script `launch_emacs.sh`:
-
-```
-#!/usr/bin/env bash
-/usr/local/bin/emacsclient --no-wait $1
-```
-
-3. Create a Platypus app with the following settings:
-
-```
-| Setting                        | Value                     |
-|--------------------------------+---------------------------|
-| App Name                       | "OrgProtocol"             |
-| Script Type                    | "env" · "/usr/bin/env"    |
-| Script Path                    | "path/to/launch-emacs.sh" |
-| Interface                      | None                      |
-| Accept dropped items           | true                      |
-| Remain running after execution | false                     |
-```
-
-Inside `Settings`:
-
-```
-| Setting                        | Value          |
-|--------------------------------+----------------|
-| Accept dropped files           | true           |
-| Register as URI scheme handler | true           |
-| Protocol                       | "org-protocol" |
-```
-
-To disable the "confirm" prompt in Chrome, you can also make Chrome
-show a checkbox to tick, so that the `OrgProtocol` app will be used
-without confirmation. To do this, run in a shell:
-
-```sh
-defaults write com.google.Chrome ExternalProtocolDialogShowAlwaysOpenCheckbox -bool true
-```
-
-
-##### Note for Emacs Mac Port
-
-If you're using [Emacs Mac Port](https://github.com/railwaycat/homebrew-emacsmacport), it
-registered its `Emacs.app` as the default handler for the URL scheme
-`org-protocol`. We have to make our `OrgProtocol.app` the default
-handler instead (replace `org.yourusername.OrgProtocol` with your app
-identifier):
-
-```
-$ defaults write com.apple.LaunchServices/com.apple.launchservices.secure LSHandlers -array-add \
-'{"LSHandlerPreferredVersions" = { "LSHandlerRoleAll" = "-"; }; LSHandlerRoleAll = "org.yourusername.OrgProtocol"; LSHandlerURLScheme = "org-protocol";}'
-```
-
-Then restart your computer.

doc/templating.md

@@ -1,119 +0,0 @@
-Rather than creating blank files on `org-roam-insert` and
-`org-roam-find-file`, it is may be desirable to prefill the file with
-content. This may include:
-
-- Time of creation
-- File it was created from
-- Clipboard content
-- Any other data you may want to input manually
-
-This requires a complex template insertion system, but fortunately,
-Org ships with a powerful one: `org-capture`. However, org-capture was
-not designed for such use. Org-roam abuses `org-capture` to some
-extent, extending its syntax. To first understand how org-roam's
-templating system works, it may be useful to look into org-capture.
-
-## Org-roam Templates
-
-The org-roam capture template extends org-capture's template with 2
-additional properties:
-
-1. `:file-name`: This is the file name template used when a new note
-   is created.
-2. `:head`: This is the template that is inserted on initial note
-   creation.
-
-### Org-roam Template Expansion
-
-Org-roam's template definitions also extend org-capture's template
-syntax, to allow prefilling of strings. In many scenarios,
-`org-roam--capture` is passed a mapping between variables and strings.
-For example, during `org-roam-insert`, a title is prompted for. If the
-title doesn't already exist, we would like to create a new file,
-without prompting for the title again.
-
-Variables passed are expanded with the `${var}` syntax. For example,
-during `org-roam-insert`, `${title}` is prefilled for expansion. Any
-variables that do not contain strings, are prompted for values using
-`completing-read`.
-
-After doing this expansion, the org-capture's template expansion
-system is used to fill up the rest of the template. You may read up
-more on this on [org-capture's documentation
-page](https://orgmode.org/manual/Template-expansion.html#Template-expansion).
-
-For example, take the template: `"%<%Y%m%d%H%M%S>-${title}"`, with the title
-`"Foo"`. The template is first expanded into `%<%Y%m%d%H%M%S>-Foo`. Then
-org-capture expands `%<%Y%m%d%H%M%S>` with timestamp: e.g.
-`20200213032037-Foo`.
-
-All of the flexibility afforded by emacs and org-mode are
-available. For example, if you want to encode a UTC timestamp in the
-filename, you can take advantage of org-mode's `%(EXP)` template
-expansion to call `format-time-string` directly to provide its third
-argument to specify UTC.
-
-``` emacs-lisp
-("d" "default" plain (function org-roam--capture-get-point)
-     "%?"
-     :file-name "%(format-time-string \"%Y-%m-%d--%H-%M-%SZ--${slug}\" (current-time) t)"
-     :head "#+TITLE: ${title}\n"
-     :unnarrowed t)
-```
-
-Similarly, if you want to change how titles are transformed into
-slugs, you can override `org-roam--title-to-slug`. For example, to use
-hyphens instead of underscores:
-
-
-``` emacs-lisp
-  (defun org-roam--title-to-slug (title)
-    "Convert TITLE to a filename-suitable slug. Uses hyphens rather than underscores."
-    (cl-flet* ((nonspacing-mark-p (char)
-                                  (eq 'Mn (get-char-code-property char 'general-category)))
-               (strip-nonspacing-marks (s)
-                                       (apply #'string (seq-remove #'nonspacing-mark-p
-                                                                   (ucs-normalize-NFD-string s))))
-               (cl-replace (title pair)
-                           (replace-regexp-in-string (car pair) (cdr pair) title)))
-      (let* ((pairs `(("[^[:alnum:][:digit:]]" . "-")  ;; convert anything not alphanumeric
-                      ("--*" . "-")  ;; remove sequential underscores
-                      ("^-" . "")  ;; remove starting underscore
-                      ("-$" . "")))  ;; remove ending underscore
-             (slug (-reduce-from #'cl-replace (strip-nonspacing-marks title) pairs)))
-        (s-downcase slug))))
-```
-
-This templating system is used throughout org-roam templates.
-
-### Template examples
-
-Here I walkthrough the default template, reproduced below.
-
-```
-("d" "default" plain (function org-roam--capture-get-point)
-     "%?"
-     :file-name "%<%Y%m%d%H%M%S>-${slug}"
-     :head "#+TITLE: ${title}\n"
-     :unnarrowed t)
-```
-
-1. The template has short key `"d"`. If you have only one template,
-   org-roam automatically chooses this template for you.
-2. The template is given a description of `"default"`.
-3. `plain` text is inserted. Other options include Org headings via
-   `entry`.
-4. `(function org-roam--capture-get-point)` should not be changed.
-5. `"%?"` is the template inserted on each call to `org-roam--capture`.
-   This template means don't insert any content, but place the cursor

-6. `:file-name` is the file-name template for a new note, if it
-doesn't yet exist. This creates a file at path that looks like
-   `/path/to/org-roam-directory/20200213032037-foo.org`.
-7. `:head` contains the initial template to be inserted (once only),
-   at the beginning of the file. Here, the title global attribute is
-   inserted.
-8. `:unnarrowed t` tells org-capture to show the contents for the
-   whole file, rather than narrowing to just the entry.

-Org-roam was built to support a workflow that was not possible with
-vanilla Org-mode. This flow is modelled after the [Zettelkasten
-method][zettelkasten], and many of [Roam Research][roam]'s workflows.
-It is crucial to understand that Org-roam does not auto-magically make
-note-taking better -- it's changing the note-taking workflow that
-does.
-
-To understand more about the methods and madness, the [Note-Taking
-Workflow][appendix:ntw] page contains a page of useful references. The
-author has also written [a post][jethro-blog-post] about how he uses
-Org-roam.
-
-## Activating Org-roam
-
-Org-roam's entry point is the global minor `org-roam-mode`. This sets
-up Emacs with several hooks, for keeping the org-roam cache
-consistently updated, as well as showing the backlinks buffer. 
-
-The cache is a sqlite database named `org-roam.db`, which resides at
-the root of the `org-roam-directory`. Activating `org-roam-mode`
-builds the cache, which may take a while the first time, but is
-generally instantaneous in subsequent runs. To build the cache
-manually again, run `M-x org-roam-db-build-cache`.
-
-## Finding a Note
-
-`org-roam-find-file` shows the list of titles for notes that reside in
-`org-roam-directory`. Selecting a note title will bring you to the
-corresponding note. Entering a title of a note that does not yet exist
-will create a new note with that title.
-
-![org-roam-find-file](images/org-roam-find-file.gif)
-
-Note that in the above image, the [ivy](https://github.com/abo-abo/swiper)
-completion frontend is used. The default frontend has some usability issues with
-non-matching candidates (e.g. when you want to enter a title of a new note,
-there is no completion candidate), so either `ivy` or `helm` is recommended.
-
-## Inserting Links
-
-`org-roam-insert` insert links to existing (or new) notes. Entering a
-non-existent title will also create a new note with that title.
-
-![org-roam-insert](images/org-roam-insert-filetag.gif)
-
-Good usage of Org-roam requires liberally linking files. This allows
-the build-up of a dense knowledge graph.
-
-## The Org-roam Buffer
-
-The Org-roam buffer is often displayed in the side window. It shows
-backlinks for the currently active Org-roam note, along with some
-surrounding context.
-
-![org-roam-buffer](images/org-roam-buffer.gif)
-
-## Exporting the Graph
-
-Org-roam also uses Graphviz to generate a graph, with notes as nodes,
-and links between them as edges. The generated graph can be used to
-navigate to the files, but this requires some additional setup
-described in the [Roam Protocol][appendix:roam-protocol] page.

+;;; Commentary:
+;;
+;; This library provides `org-roam-doctor', a utility for diagnosing and fixing
+;; Org-roam files. Running `org-roam-doctor' launches a list of checks defined
+;; by `org-roam-doctor--checkers'. Every checker is an instance of
+;; `org-roam-doctor-checker'.
+;;
+;; Each checker is given the Org parse tree (AST), and is expected to return a
+;; list of errors. The checker can also provide "actions" for auto-fixing errors
+;; (see `org-roam-doctor--remove-link' for an example).
+;;
+;; The UX experience is inspired by both org-lint and checkdoc, and their code
+;; is heavily referenced.
