Module render 

Doc → gpui elements.

Numbers drive layout (sizes, line heights, paddings — the constants here); colors are paint, read from Theme. Blocks are a flat list, so nesting is left padding rather than nested containers, and the gap between two blocks is decided by the pair: list items sit tight, everything else breathes.

Ported from zeronsh/comet (MIT) and rebuilt against the flat block model.

Structs

BlockLayouts

Where each block’s text landed, recorded as it painted.

Editing

What an editor paints over a document.

FenceHost

What an editor lends the blocks an installed crate::BlockRenderer paints — see Editing::fence.

Flat

Inline content flattened for shaping: one string, its runs, and the ranges that need painting underneath (link clicks, inline-code washes, mentions).

LeaveBlock

Return focus from inside a painted fence to the document around it.

Mention

A mention as it is shown: a favicon slot, then its label and title.

Shown

Where a mention’s range in a Text and its range in a Flat line up, in document order, as (text, flat) pairs.

Enums

Annotation

A range the caller wants washed, and which wash it gets.

Caption

What an image’s one authored string is doing on the page.

CopyButton

Whether a fence paints the button that copies its text.

ImageOverlayCorner

The picture corner holding an app’s hover control.

Toggle

Who answers a press on a task block’s checkbox.

Constants

PAINTED_CONTEXT

The key context around every painted fence. An editor’s bindings stop at it, so keys typed into a control the block paints stay that control’s.

PLAIN_LANGUAGE

What a fence with no info string calls itself, in its header and in a picker — one spelling, so the label and the menu row cannot disagree.

TABLE_CONTROL_SIZE

Reserved lane for editor table controls, inside the block bounds.

Functions

flatten

Marks are ranges, gpui wants consecutive runs — so cut the text at every mark boundary and ask which marks cover each piece.

flatten_with

flatten with the app’s own marks painted — see crate::MarkPaint — and each mention described by preview. A name the app does not paint reads as the text it wraps.

image_source

What gpui loads for an image URL as written in a document.

markdown

Parse and render in one step — the common case for read-only content.

render

Render a document.

render_source

Paint a document’s own markdown source: a fence’s caret, selection and hit testing, without a fence’s box, band or copy button.

render_with

Render a document with a caret and a selection in it.

Type Aliases

ImageOverlay

Builds a picture’s hover control from its block index and original URL.

OnImage

Handed the image block whose picture was clicked — see Editing::image.

OnLeave

Handed the block a painted fence is leaving — see FenceHost::leave.

OnRewrite

Handed a fence’s block index and its new code — see FenceHost::rewrite.

OnToggle

Handed the block whose checkbox was clicked — see Toggle::Handled.
