412-422: Consider creating a dedicated FLEX Function Reference index page.

The PR adds a parent field parent: FLEX Function Reference to all 40+ FLEX function documentation files, but this index page (udfs/index.md) does not contain or reference a dedicated "FLEX Function Reference" page. This suggests a missing intermediate navigation layer that should be created.

Recommendation: Create udfs/flex/index.md (or similar) with:

  • YAML front matter: layout: default, title: FLEX Function Reference, parent: UDFs - User Defined Functions, has_children: true
  • Content describing the FLEX library and its function categories
🔎 Proposed FLEX Function Reference index structure

You should create a file at udfs/flex/index.md with:

---
layout: default
title: FLEX Function Reference
parent: UDFs - User Defined Functions
has_children: true
---

# FLEX Function Reference

FLEX is FalkorDB's open source community UDF package providing:

1. String and set similarity metrics for fuzzy matching
2. Date and time manipulation, formatting, and parsing
3. Low-level bitwise operations
4. Collections and list operations
5. JSON parsing and serialization
6. Map operations

[Learn more about FLEX](https://github.com/FalkorDB/flex)

This creates the hierarchy: UDFs → FLEX Function Reference → Individual Functions


412-422: Update FLEX section to reference the dedicated FLEX Function Reference page.

Once the FLEX Function Reference index is created, update the FLEX section to link to it for more comprehensive documentation and navigation.

The table output in Example 2 uses pipes, which is good. However, the alignment might not render correctly depending on the markdown renderer. This is a minor observation.

🔇 Additional comments (46)
udfs/flex/text/replace.md (1)

1-6: YAML front matter is correctly configured.

The parent page "FLEX Function Reference" (udfs/flex/index.md) and grand_parent page "UDFs - User Defined Functions" (udfs/index.md) exist with matching titles. The three-level navigation hierarchy aligns with the PR objective and is consistent across all 41 files in this navigation restructuring.

udfs/flex/text/repeat.md (3)

1-7: Verify the H1 heading matches the page title metadata.

Line 8 contains the H1 heading # text.repeat, which should match the title field in the YAML front matter (line 3: title: text.repeat). While this currently aligns, confirm that the title casing convention is consistent with other UDF files in the PR and reflects the canonical function name.


8-92: Original documentation content preserved correctly.

The functional documentation (lines 8–92) remains unchanged. The structure is clear with proper sections (Description, Syntax, Parameters, Returns, Examples, Notes, See Also), and the examples are well-illustrated.


1-6: Parent navigation structure is properly configured.

The YAML front matter establishes a correct navigation hierarchy. Both parent pages exist with matching titles: udfs/flex/index.md has title: FLEX Function Reference, and udfs/index.md has title: UDFs - User Defined Functions. Both parent pages are configured with has_children: true for proper Just the Docs navigation. All relative links in the "See Also" section resolve correctly.

udfs/flex/text/indexesOf.md (1)

1-6: YAML front matter correctly establishes navigation structure for Just the Docs.

The metadata hierarchy (grand_parent → parent → child) is properly configured. The parent page "FLEX Function Reference" and grand_parent page "UDFs - User Defined Functions" both exist with the required has_children: true configuration in their front matter, and all title references match correctly.

udfs/flex/collections/union.md (1)

1-6: Navigation metadata correctly structured.

udfs/flex/index.md (1)

1-6: Index page properly configured as navigation parent.

The front matter correctly designates this page as the parent ("FLEX Function Reference") with has_children: true, enabling Just the Docs to render child pages. The two-level hierarchy (UDFs → FLEX Function Reference → individual functions) is properly established.

udfs/flex/map/fromPairs.md (1)

1-6: Navigation hierarchy correctly configured.

The YAML front matter positions this function page in the proper Just the Docs navigation tree. Consistent with the broader pattern across all individual function pages.

1-6: Navigation structure completeness verified.

All verification points confirm proper setup:

  • 41 FLEX function pages have consistent parent/grand_parent hierarchy
  • "FLEX Function Reference" parent page exists at udfs/flex/index.md with correct configuration and has_children: true
  • "UDFs - User Defined Functions" grand_parent page exists at udfs/index.md with has_children: true

The Just the Docs navigation tree is properly configured.

udfs/flex/json/fromJsonMap.md (3)

10-11: Clarify whether the description change is a documentation update or behavior change.

The description now explicitly states "Safely handles malformed JSON by returning an empty map on parse errors." Verify this is a documentation clarification of existing behavior rather than a new feature, and ensure consistency with related functions (e.g., fromJsonList).


78-80: Relative path references are correctly configured.

Both referenced files (fromJsonList.md and toJson.md) exist in the same directory as expected. The "See Also" references are properly discoverable.


1-6: No action required. The parent page "FLEX Function Reference" exists at udfs/flex/index.md with proper Just the Docs configuration including layout: default, has_children: true, and correct parent reference.

udfs/flex/text/levenshtein.md (2)

1-6: YAML front matter is consistent and properly configured.

The metadata structure (layout, title, parent, grand_parent) aligns with the PR's navigation standardization. No issues identified.


73-75: No changes required. The cross-category reference paths are correct. Both ../similarity/jaccard.md and ./jaroWinkler.md exist in the expected locations relative to levenshtein.md, and the directory structure properly supports these references.

udfs/flex/date/toTimeZone.md (1)

1-6: YAML front matter is correctly configured.

The metadata follows the standardized pattern. No issues identified.

udfs/flex/text/camelCase.md (1)

1-6: YAML front matter is correctly configured.

The metadata follows the standardized pattern with proper parent-child hierarchy for Just the Docs navigation.

udfs/flex/collections/intersection.md (2)

1-6: YAML front matter is correctly configured.

The metadata establishes proper navigation hierarchy within the FLEX Function Reference.


76-78: Cross-category "See Also" reference path is correct.

The reference to ../similarity/jaccard.md resolves properly from the collections/ directory. Both the union.md and jaccard.md files exist at their expected locations.

udfs/flex/bitwise/shiftLeft.md (2)

1-6: YAML front matter is correctly configured.

The metadata properly establishes this function's place in the FLEX Function Reference navigation hierarchy.


74-79: Document JavaScript 32-bit limitation clearly for users.

The Notes section correctly mentions "Operates on 32-bit signed integers in JavaScript," which is important context. This is well-documented and appropriate.

udfs/flex/text/rpad.md (1)

1-6: YAML front matter is correctly configured.

The metadata follows the established pattern and properly positions this function in the navigation hierarchy.

udfs/index.md (1)

1-5: YAML front matter structure is appropriate for a parent/index page.

The has_children: true field correctly indicates this is a parent page. The absence of a grand_parent field is correct for a top-level section.

udfs/flex/json/fromJsonList.md (3)

8-79: Documentation content is well-structured and comprehensive.

The file follows a clear organizational pattern with all essential sections. Examples effectively cover basic usage, complex scenarios, real-world data processing, and error handling. The Notes section provides practical guidance for developers.


80-82: Cross-reference links are valid. Both ./fromJsonMap.md and ./toJson.md exist in the udfs/flex/json/ directory and contain proper documentation structure with Jekyll front matter.


1-6: YAML front matter correctly establishes navigation hierarchy for Just the Docs.

The metadata is properly configured with valid parent and grand_parent pages:

  • FLEX Function Reference (udfs/flex/index.md) has has_children: true
  • UDFs - User Defined Functions (udfs/index.md) exists at the hierarchy root with has_children: true

Cross-referenced files (fromJsonMap.md, toJson.md) are present in the same directory.
