fix(css): split @value imports on the from keyword - #22306
Conversation
parseValueAtRuleParams located the `from` separator in
`@value <names> from <source>` with `str.lastIndexOf("from")`. When the
source path or an import name contained the substring `from` (e.g.
`./from-colors.module.css`), the split landed inside the path, so names
and source were mis-parsed and the import never resolved.
Split on the first whitespace-delimited `from` keyword instead, matching
postcss-modules-values semantics. Comments are already replaced with
spaces before the split, so the keyword is reliably whitespace-delimited.

In `@lib/css/CssParser.js`:
- Line 570: Update the `fromMatch` separator in the CSS `@value` import parser
to use only CSS whitespace characters (space, tab, newline, form feed, and
carriage return) on both sides of `from`, so non-breaking spaces remain part of
the import name.

JS \s also matches U+00A0 and other spaces that are valid inside an import name, which could select a from inside the name; limit both separator boundaries to the CSS whitespace set (space, tab, LF, FF, CR). Signed-off-by: Eshiv Pandey <[email protected]>

Summary
CssParser.parseValueAtRuleParamslocates thefromseparator in@value <names> from <source>withstr.lastIndexOf("from"). When the source path (or an import name) contains the substringfrom(e.g.@value primary from "./from-colors.module.css"),lastIndexOfmatches inside the path, so the names and source are mis-split: the request never resolves and the values are left unsubstituted. This splits on the first whitespace-delimitedfromkeyword instead, matchingpostcss-modules-valuessemantics. Comments are already replaced with spaces before the split, so the keyword stays reliably whitespace-delimited. Same small-fix shape as #22280, #22281 and #22303.What kind of change does this PR introduce?
fix
Did you add tests for your changes?
Yes.
test/configCases/css/css-modules-value-from-in-pathimports two@values from./from-colors.module.css(one import name also containsfrom) and asserts the emitted CSS substitutes the imported values (rebeccapurple,10px) rather than leaving the identifiers in place. It fails without the fix (thefrom-containing request never resolves) and passes with it.Does this PR introduce a breaking change?
No. Existing
@value ... fromimports whose paths contain nofromsubstring split identically under both the oldlastIndexOfand the new keyword match; only the previously-broken case now resolves.If relevant, what needs to be documented once your changes are merged or what have you already documented?
n/a
Use of AI
AI (Claude Code) was used to help locate the substring mis-split, draft the fix, and write the integration test; all changes were reviewed and verified locally by me.
Summary by CodeRabbit
@valueimports so paths containing “from” are parsed correctly, and CSS whitespace—not non-breaking spaces—separates thefromkeyword from the path. Imported values are applied to styles.
