feat(CopySnippet, PrismCode): add an isWrapped prop to soft-wrap long content - #1335
Merged
Conversation
By default CopySnippet keeps each line on one line and scrolls horizontally, which pushes long error messages and logs off to the right. `wrap` lays the content out on multiple lines instead: the block grows vertically to fit (so even a single very long line is fully readable rather than clamped to the collapsed height), and unbreakable runs like URLs, tokens and identifiers wrap too (overflow-wrap: anywhere), not just spaces. It reuses the existing multiline block layout and only adds white-space handling on the inner <code>, so behaviour is unchanged when the prop is unused. `nowrap` still wins. `wrap` is omitted from the inherited Card container styles (it maps to flex-wrap, meaningless on this grid-based component) so the name can carry the boolean prop. Also fixes the docs, which showed a non-existent `multiline` prop. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

What
Adds an
isWrappedprop toPrismCodeandCopySnippetthat soft-wraps long content onto multiple lines instead of scrolling it horizontally.By default both components keep each line on one line and scroll sideways, which buries long error messages and logs off to the right.
isWrappedlays the content out on multiple lines: unbreakable runs like URLs, tokens and identifiers break too (overflow-wrap: anywhere), not just spaces. OnCopySnippetthe block additionally grows vertically to fit — so even a single very long line is fully readable rather than clamped to the collapsed single-line height.Why
Cube Cloud CUB-4032 — long error messages shown in
PrismCode/CopySnippetforce horizontal scrolling. The wrap belongs in the components: the global Prism CSS pinswhite-space: preoncode[class*="language-"], so it cannot be reliably overridden from outside, andCopySnippetadditionally clamps the single-line height.Design
PrismCodeowns the wrapping (white-space: pre-wrap+overflow-wrap: anywhereon itsCodesub-element, keyed on awrappedmod).CopySnippetforwards the prop to its innerPrismCodeand only adds its own layout switch (auto height, multiline button placement).isWrappedfollows the library'sis*boolean convention (isDisabled,isLoading,isClearable, …) and avoids reading as the opposite ofCopySnippet'snowrap— the two are different axes:nowrapcollapses real newlines into one scrolling line,isWrappedbreaks long lines.nowrapwins when both are set.Wrappedstories for both components, a unit test for thewrappedmod, and a changeset (minor).Verified in a real browser (Storybook) across corner cases: short/empty code,
