Matterhorn.Types.RichText

Description

This module provides a set of data types to represent message text. The inline and block types in this module are designed to represent most of what is found in Markdown documents (particularly the Commonmark specification) in addition to other things we find in Mattermost messages, such as username or channel references.

To parse a Markdown document, use parseMarkdown. To actually render text in this representation, see the module RichText.

unBlocks :: Blocks -> Seq Block Source #

data Block Source #

A block in a rich text document.

NOTE: update sameBlockType when constructors are added to this type.

Constructors

Para Inlines	A paragraph.
Header Int Inlines	A section header with specified depth and contents.
Blockquote Blocks	A blockquote.
List ListType ListSpacing (Seq Blocks)	An itemized list.
CodeBlock CodeBlockInfo Text	A code block.
HTMLBlock Text	A fragment of raw HTML.
HRule	A horizontal rule.

Show Block Source #
Instance details Defined in Matterhorn.Types.RichText Methods showsPrec :: Int -> Block -> ShowS # show :: Block -> String # showList :: [Block] -> ShowS #

sameBlockType :: Block -> Block -> Bool Source #

Returns whether two blocks have the same type.

data CodeBlockInfo Source #

Information about a code block.

Constructors

CodeBlockInfo
Fields codeBlockLanguage :: Maybe Text The language of the source code in the code block, if any. This is encoded in Markdown as a sequence of non-whitespace characters following the fenced code block opening backticks. codeBlockInfo :: Maybe Text Any text that comes after the language token. This text is separated from the language token by whitespace.

data Inline Source #

The kinds of inline values that can appear in rich text blocks.

Constructors

EText Text	Plain text that SHOULD be a contiguous sequence of non-whitespace characters.
EEmph Inlines	Emphasized (usually italicized) content.
EStrikethrough Inlines	Strikethrough content.
EStrong Inlines	Boldface content.
ECode Inlines	A sequence of non-whitespace characters.
ESpace	A single space.
ESoftBreak	A soft line break.
ELineBreak	A hard line break.
ERawHtml Text	Raw HTML.
EEditSentinel Bool	A sentinel indicating that some text has been edited (used to indicate that mattermost messages have been edited by their authors). This has no parsable representation; it is only used to annotate a message prior to rendering to add a visual editing indicator. The boolean indicates whether the edit was "recent" (True) or not (False).
EUser Text	A user reference. The text here includes only the username, not the sigil.
EChannel Text	A channel reference. The text here includes only the channel name, not the sigil.
EHyperlink URL Inlines	A hyperlink to the specified URL. Optionally provides an element sequence indicating the URL's text label; if absent, the label is understood to be the URL itself.
EImage URL Inlines	An image at the specified URL. Optionally provides an element sequence indicating the image's "alt" text label; if absent, the label is understood to be the URL itself.
EEmoji Text	An emoji reference. The text here includes only the text portion, not the colons, e.g. "foo" instead of ":foo:".
ENonBreaking Inlines	A sequence of elements that must never be separated during line wrapping.
EPermalink TeamURLName PostId (Maybe Inlines)	A permalink to the specified team (name) and post ID with an optional label.

parseMarkdown Source #

Arguments

:: Maybe TeamBaseURL	If provided, perform post link detection whenever a hyperlink is parsed by checking to see if the post link is a post in this Mattermost team
-> Text	The markdown input text to parse
-> Blocks

Parse markdown input text to RichText.

Note that this always returns a block sequence even if the input cannot be parsed. It isn't yet clear just how permissive the commonmark parser is, but so far we have not encountered any issues. If the input document is so broken that commonmark cannot parse it, we return an empty block sequence.

findUsernames :: Blocks -> Set Text Source #

Obtain all username references in a rich text document.

blockGetURLs :: Block -> [(Either (TeamURLName, PostId) URL, Maybe Inlines)] Source #

Obtain all URLs (and optional labels) in a rich text block.

findVerbatimChunk :: Blocks -> Maybe Text Source #

Find the first code block in a sequence of rich text blocks.
