Data markup: layers that say what text is, kept by WithoutVisualMarkup() by HarryCordewener · Pull Request #67 · SharpMUSH/MarkupString

HarryCordewener · 2026-10-15T05:09:35Z

Requested by Grave · project thread

Before: every layer was visual. A layer that only records a fact about the text (that a character separates list items) had no place: stripping colour meant ToPlainText(), which dropped it too.

After: IDataMarkup marks such a layer. No format draws it, and MarkupText.WithoutVisualMarkup() returns the plain text with the data layers still on their characters.

SharpMUSH uses this for list separators (%*<|>): a separator that is an ordinary character plus a data layer, so a list function splits only on marked separators and never on a | inside a box border or typed text.

How: the renderer takes data layers off each run before points, set emitters or per-layer emitters see it; a run with nothing else is written as encoded plain text, and an emitter registered for a data type is never called. WithoutVisualMarkup() rebuilds the text from its runs, dropping points with their carriers as ToPlainText() does, and joins data runs that colour had split. Docs: custom-markup.md (Data markup), text-operations.md (Transforming). CHANGELOG opens 2.21.0.

Tests: DataMarkupTests (9). Full suite: 1357 passed.

Summary by CodeRabbit

New Features
- Added data markup for classifying text without changing its appearance. It travels with text through text operations and serialization, is ignored when comparing text, and is omitted from rendered output without invoking markup emitters.
- Added options to remove visual markup while keeping data markup, or remove data markup while preserving visual styling and point markup.
Documentation
- Added guidance on data markup and the options for removing visual or data markup.

IDataMarkup marks a layer that says what text is rather than how it looks, such as a list separator. The renderer takes data layers off each run before any emitter sees it; WithoutVisualMarkup() strips every other layer and keeps them.

Walkthrough

The change adds IDataMarkup for non-visual text layers and removes those layers before format emission. It adds MarkupText.WithoutVisualMarkup() to remove visual markup while preserving data markup. It also adds MarkupText.WithoutDataMarkup() to remove data markup while preserving visual markup and points.

Changes

Merge Risk: 🔵 Low · up to 02715

Data layers can still reach emitters despite the stated rendering contract. This is a bounded compatibility risk that should be addressed or explicitly accepted before merging.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Filter data before emitter selection and context construction.

For a run with data and visual layers, EmitContext.Markups still contains the data layer, even though markups is filtered here. Visual emitters can therefore observe data through the context. A layer that implements both IDataMarkup and IBlockMarkup can also reach TryRenderBlock before this filter. Filter the run and adjacent context sets before dispatch, and exclude data layers from block selection.

Leaving this as is for now. The PR is on hold while we decide whether the engine still needs data markup at all. If the PR goes ahead, the filter moves ahead of emitter selection and block dispatch in its next code push.

Closing this. SharpMUSH is solving list-separator collisions with a plain-text makedelim() function instead of marked separators, because a player could forge a mark in their own evaluated input. Nothing needs data markup now.

Reopened: marked separators are back on, with typed text unmarked by the consumer. This adds MarkupText.WithoutDataMarkup(), which takes the data layers off and keeps the colour and points. SharpMUSH's unmark(), secure() and escape() use it. SharpMUSH/SharpMUSH#1885 needs 2.21.0 from this PR.
