parsing.ts uses YAML.parse() which fails on multi-document YAML (frontmatter)

[cioinside]

Summary

packages/ragmir-core/src/parsing.ts (compiled to dist/parsing.js:86-88) uses YAML.parse() to handle .yaml/.yml files. This rejects any file containing multiple YAML documents — including the widely-used pattern of YAML frontmatter (Hugo, Jekyll, Eleventy, Hexo, Pelican, etc.).

# Title

This is the body of the YAML document.

import YAML from "yaml";
import fs from "node:fs";
const text = fs.readFileSync("test.yaml", "utf8");
YAML.parse(text);
// throws:
//   Source contains multiple documents; please use YAML.parseAllDocuments()
//   at line 5, column 1

Run rgr ingest against a project that contains such a file → the file is rejected at parse time and is not indexed. There is no warning to the user beyond the bare error message.

Expected

Multi-document YAML files parse successfully. All documents are concatenated into indexable text.

Root cause

packages/ragmir-core/src/parsing.ts (compiled dist/parsing.js):

case ".yaml":
case ".yml": {
    text = YAML.stringify(YAML.parse(await readFile(file.absolutePath, "utf8")));
    break;
}

YAML.parse() from the yaml npm package (v2.9.0) refuses multi-document sources. The package exposes YAML.parseAllDocuments() specifically for this case.

Proposed fix

 case ".yaml":
 case ".yml": {
-    text = YAML.stringify(YAML.parse(await readFile(file.absolutePath, "utf8")));
+    const docs = YAML.parseAllDocuments(await readFile(file.absolutePath, "utf8"));
+    text = docs.map((d) => YAML.stringify(d)).join("\n");
     break;
 }

Concatenate all documents as indexable text. Empty / frontmatter-only documents stringify to null; the downstream pipeline already treats null text as a no-op.

Environment

• @jcode.labs/ragmir 4.4.0
• yaml 2.9.0 (matches package.json dependency)
• Node 22.23.1

Tested workaround

Applied a one-line patch to the installed dist/parsing.js:

-    text = YAML.stringify(YAML.parse(await readFile(file.absolutePath, "utf8")));
+    const docs = YAML.parseAllDocuments(await readFile(file.absolutePath, "utf8"));
+    text = docs.map((d) => YAML.stringify(d)).join("\n");

After the patch, rgr ingest processes multi-document YAML files cleanly.
