style/prose-space ​

Collapses repeated ASCII spaces between prose words without moving line breaks: a. b c becomes a. b c. It normalizes spacing in documents that keep their authored line breaks, without the reflow of style/wrap.

Style rule, fixed by format. Presets: none. Dialects: all. Options: none.

Before:

markdown
a.  b   c
next  line

After:

markdown
a. b c
next line

To keep line breaks as written and collapse spaces only:

json
{ "rules": { "style/wrap": "off", "style/prose-space": "warn" } }

Edge cases and advanced usage ​

Details: link text counts as prose. This rule and style/wrap agree on one space between prose words. It is opt-in because sentence spacing can be an intentional source convention.

Left as written: leading indentation, trailing spaces (including hard breaks), non-breaking spaces, code, math, images, link destinations and titles, and table cells. A block containing inline HTML stays whole, since HTML can make whitespace significant; HTML blocks and front matter stay literal too. Renderer and semantic checks keep the source wherever changing spaces would change meaning.

Reported without a fix: spaces in # and underlined headings, in every dialect, because changing heading text can change anchors and heading links.

Dialect notes ​

In VitePress: projection syntax and Vue {{ }} interpolations keep their spaces without a finding: expressions can contain whitespace-sensitive JavaScript strings.
