_Subject_ and _mail body_ are parsed by [Golang's template engine](https://golang.org/pkg/text/template/) and
are provided with a _metadata context_ assembled for each notification. The context contains the following elements:

| Name | Type | Available | Usage |
|--------------------|----------------|---------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `.FallbackSubject` | string | Always | A default subject line. See Below. |
| `.Subject` | string | Only in body | The _subject_, once resolved. |
| `.Body` | string | Always | The message of the issue, pull request or comment, parsed from Markdown into HTML and sanitized. Do not confuse with the _mail body_ |
| `.Link` | string | Always | The address of the originating issue, pull request or comment. |
| `.Issue` | models.Issue | Always | The issue (or pull request) originating the notification. To get data specific to a pull request (e.g. `HasMerged`), `.Issue.PullRequest` can be used, but care should be taken as this field will be `nil` if the issue is *not* a pull request. |
| `.Comment` | models.Comment | If applicable | If the notification is from a comment added to an issue or pull request, this will contain the information about the comment. |
| `.IsPull` | bool | Always | `true` if the mail notification is associated with a pull request (i.e. `.Issue.PullRequest` is not `nil`). |
| `.Repo` | string | Always | Name of the repository, including owner name (e.g. `mike/stuff`) |
| `.User` | models.User | Always | Owner of the repository from which the event originated. To get the user name (e.g. `mike`),`.User.Name` can be used. |
| `.Doer` | models.User | Always | User that executed the action triggering the notification event. To get the user name (e.g. `rhonda`), `.Doer.Name` can be used. |
| `.IsMention` | bool | Always | `true` if this notification was only generated because the user was mentioned in the comment, while not being subscribed to the source. It will be `false` if the recipient was subscribed to the issue or repository. |
| `.SubjectPrefix` | string | Always | `Re: ` if the notification is about other than issue or pull request creation; otherwise an empty string. |
| `.ActionType` | string | Always | `"issue"` or `"pull"`. Will correspond to the actual _action type_ independently of which template was selected. |
| `.ActionName` | string | Always | It will be one of the action types described above (`new`, `comment`, etc.), and will correspond to the actual _action name_ independently of which template was selected. |

The template system contains several functions that can be used to further process and format
the messages. Here's a list of some of them:

| `AppUrl` | - | Any | Gitea's URL |
| `AppName` | - | Any | Set from `app.ini`, usually "Gitea" |
| `AppDomain` | - | Any | Gitea's host name |
| `EllipsisString` | string, int | Any | Truncates a string to the specified length; adds ellipsis as needed |
| `Str2html` | string | Body only | Sanitizes text by removing any HTML tags from it. |
