-# Boilerplate in Mycorrhiza codebase
-
-Being programmed by Go, mostly by Bouncepaw, the codebase contains a lot of boilerplate. This document is an attempt to describe how it is done.
-
-## Modules
-
-Mycorrhiza is arranged in quite many packages. They are thematic. For example, package `backlinks` has all things backlinks, including the storage, the views, and exported functions (not many, ideally). Such packages can be called modules, if you want.
-
-## Views
-
-Views are the biggest source of similar code. Before the transition from QTPL to Go's standard templates, this boilerplate energy was split differently, but was not instantly obvious. The current approach does not really introduce new boilerplate energy, but it does focus it, resulting in actual boilerplate. I hope you get the idea.
-
-All related views are part of one module.
-
-Views come in multiple parts.
-
-The first part is the template itself. Call template files like that: `view_user_list.html`, prefixed with `view_`. The boilerplate is as follows.
-
-```html
-{{define "title"}}{{end}}
-{{define "body"}}
-{{end}}
-```
-
-More often than not, you will want to make template `title` a different template in the same file. See existing files for inspiration.
-
-The code that makes those templates runnable lies in one file. This is the second part. It contains the following:.
-
-The Russian translation is a `string` variable called `ruTranslation`; we currently have no other translations, but they are to be called like `frTranslation`, `eoTranslation`, et cetera.
-
-
-```go
-var (
-	ruTranslation = `
-{{define "one thing"}}...{{end}}
-{{define "other thing"}}...{{end}}
-`
-	...
-)
-```
-
-Chains are collection of different language variants of the same template. Declare them and then assign them in a function, which you call somewhere (not just `init`!).
-
-```go
-var (
-	ruTranslation              = `...`
-	chainStuff, chainAddStuff viewutil.Chain
-)
-
-func initViews() {
-	chainStuff = viewutil.CopyEnRuWith(fs, "view_stuff.html", ruTranslation)
-	chainAddStuff = viewutil.CopyEnRuWith(fs, "view_add_stuff.html", ruTranslation)
-}
-```
-
-Then every view has a runner and its own datatype.
-
-```go
-//...
-
-type dataStuff struct {
-	*viewutil.BaseData
-	StuffName string
-}
-
-func viewStuff(meta viewutil.Meta, stuffName string) {
-	viewutil.ExecutePage(meta, chainStuff, dataUserList{
-		BaseData: &viewutil.BaseData{},
-		StuffName: stuffName,
-	})
-}
-```
-
-Sometimes, two datatypes of different views are the same, it is ok to just share one, but name it so that it mentions both.
-
-Avoid any logic in those runners. Keep them as boilerplate as they are. You rarely need to fill the `BaseData` field. Do it if you need to. If you don't, `viewutil.ExecutePage` will do its best to guess. We name the fields with capital letters.
-
-### Troubleshooting
-
-* Declared the chains?
-* Assigned the chains?
-* Assigned the chains, sure?
-* Used the correct data type?
-* `*viewutil.BaseData` is there?
-* Used the correct chain?

-* `wiki.git/` is the Git repository of the wiki, it has all hyphae in it. You can edit it directly, but do not forget to make Git commits with your changes and [[/reindex]] you wiki afterwards.
-* `static` holds static data. You can access data there from your wiki with addresses like `/static/image.png`.
-** `static/favicon.ico` is your wiki's favicon, accessed at [[/favicon.ico]] by browsers.
-** `static/default.css` redefines the engine's default style, if exists. You probably don't need to use it.
-** `static/custom.css` is loaded after the main style. If you want to make visual changes to your wiki, this is probably where you should do that.
-** `static/robots.txt` redefines default `robots.txt` file.
-* `categories.json` contains the information about all categories in your wiki.
-* `users.json` stores users' information. The passwords are not stored, only their hashes are, this is safe. Their tokens are stored in `cache/tokens.json`.
-* `interwiki.json` holds the interwiki configuration.
-* `cache/` holds cached data. If you back up your wiki, you can omit this directory.
-** `cache/tokens.json` holds users' tokens. By deleting specific tokens, you can log out users remotely.
-* Mycomarkup migration markers are hidden files prefixed with `.mycomarkup-`. You should probably not touch them.

-= Interwiki
-**Interwiki** is a means of bringing wikis together, making a federation of them. In Mycorrhiza, one aspect of interwiki is supported: the interwiki links, or the **interlinks**. Most other wiki systems support them too. Interwiki links are shown in green.
-
-In Mycomarkup, you can address a different wiki by prefixing the link target with a name and a `>` character. For example:
-```myco
-[[Wikipedia>Wiki]]
-=> Mycorrhiza>deployment
-```
-
-The interwiki prefixes obey the same naming rules as hyphae. In particular, they are case-insensitive, among other things. Every interwiki entry has one main name and it might have any number of aliases, which can be used interchangeably.
-
-See [[/interwiki]] for the list of configured interwiki entries. Unlike the WWW, there is no distributed list of wikis similar to DNS, so each wiki administrator has to maintain their own list.
-
-== Mycorrhiza interwiki
-Intermycorrhizal interwiki works the best, due to the nature of hyphae. Unlike with some other systems, you can address images from the other wikis reliably.
-
-```myco
-img {
-   melanocarpa>quadrat 12
-}
-```
-
-== Setting the intermap
-//This section is meant for wiki administrators.//
-**Intermap**, or interwiki map, is the collection of all configured interwiki entries. To configure it, an administrator has to visit [[/interwiki]] and change the existing entries or add a new one.
-
-Entries have the following fields:
-*. {
-   **Name.** This is the canonical name of the wiki and one of the prefixes you can use for interlinks.
-}
-*. {
-   **Aliases.** They are separated with commas. You don't have to set them up.
-
-   A good idea is to have the full name in the //name// field (such as `wikipedia`), and shorter names in //aliases// (such as `pedia` and `wp`).
-}
-*. {
-   **URL.** The URL of the index/home/main page of the wiki. It should not end on trailing slash.
-}
-*. {
-   **Engine.** This is the software the target wiki runs.
-
-   There are two engines supported explicitly:
-   * Mycorrhiza
-   * [[https://anagora.org | Agora]]
-
-   Choose the //Generic// option for sites running different software.
-}
-*. {
-   **Formats.** Because interlinks are supported for two cases (hyperlinks and images), there has to be a way to convert a resource name to an URL of the resource. Format strings are a way to do that.
-
-   There are two format strings: one for hyperlinks, one for images. They directly correspond to HTML's `href` and `src` attributes of the `a` and `img` tags.
-
-   For Mycorrhiza wikis, you don't have to set them, they are set automatically to the following values (replace `https\:/\/example.org` with the URL of the target wiki):
-   * Link: `https\:/\/example.org/hypha/{NAME}`
-   * Image: `https\:/\/example.org/binary/{NAME}`
-
-   For Agora, they are set to:
-   * Link: `https\:/\/example.org/node/{NAME}`
-   * Image: `https\:/\/example.org/{NAME}`, which doesn't make a lot of sense
-
-   For generic sites, you will have to think of something by yourself. If you do not set it, it will default to `https\:/\/example.org/{NAME}`.
-
-   `{NAME}` is substituted. For example, from link `[\[Melanocarpa\>uxn]]`, `{NAME}` is replaced with `uxn`.

-You can also change `interwiki.json` directly. Reload the wiki after editing it.

-= Renaming
-You can **rename** existing hyphae. On the bottom of the hyphae, there is a //Rename// link. Follow it to open the renaming dialog.
-
-> You can also access the dialog by pressing `r` or visiting URL `/rename/<hypha name>`.
-
-Set the new name there. If you don't change it, submitting the form does nothing. Two options are set by default.
-
-*. **Rename subhyphae too.** If on, subhyphae will remain subhyphae after the renaming. {
-For example, if you had hyphae //Apple// and //Apple/red// and renamed //Apple// to //Malum//, //Apple/red// would also be renamed to //Malum/red//.
-}
-*. **Leave redirections.** If on, the old name will not remain empty. Rather than that, a hypha with a link to the new name is left. This hypha is called a **redirection hypha**. This option also combines with the other option, i/e subhyphae will receive their corresponding redirection hyphae.
-
-== Redirection hyphae category
-All redirection hyphae are added to a specific category. By default, the category is [[/category/redirection | Redirection]]. This way, you can find all redirections and modify them.
-
-=== How to change the category
-//This section is for wiki administrators only.//
-
-*. Edit `config.ini`
-*. Change the `RedirectionCategory` value in the `[Hyphae]` section.
-*. Save the file, restart the wiki.

+= Sibling hyphae section
+On the right (or below on smaller devices) of hypha pages there is a special section that lists **sibling hyphae**.
+
+> **Sibling hyphae** are hyphae that are subhyphae of the same hypha. For example, //Fruit/Apple// and //Fruit/Pear// are sibling hyphae to each other.
+
+The sibling hyphae are listed alphabetically. The name of the hypha you are currently viewing is also part of the list. The rest are links that lead you to the hyphae.
+
+Sometimes, there are numbers beside the links:
+* **No number.** The hypha has no subhyphae.
+* **One number.** The number indicates how many direct subhyphae it has.
+* **Two numbers.** The first number is the number of direct subhyphae. The second number in parentheses is the number of indirect subhyphae.
+
+For hypha //Fruit//, hyphae //Fruit/Apple// and //Fruit/Pear// would be direct subhyphae, and hyphae //Fruit/Apple/Red// and //Fruit/Apple/Green// would be indirect subhyphae.

-= Today links
-Some people use Mycorrhiza to keep their diaries. They put each day's notes into separate hyphae, usually named in the ISO format, for example, `2024-06-01` for the 1st of June, 2024. This date format is especially handy because it aligns with the way Mycorrhiza sorts hyphae, so the days are in order.
-
-Links [[/today]] and [[/edit-today]] are special links that redirect to or edit the “today” hypha. Put them on your home hypha or on [[/help/en/top_bar | the top bar]].
