Summary
Fixes the convert command's link style conversion functionality by implementing the previously empty
convertLinkStylemethod. This resolves the issue wheremarkmv convert --link-style combinedwould report "No changes needed" even when there were standard markdown links that should be converted.Problem
The
convertLinkStylemethod inLinkConverterwas just a placeholder that always returnedfalse, meaning no link style conversions were ever performed. This caused the convert command to incorrectly report "No changes needed" for all link style conversion requests.Solution
Key Changes
Implemented full
convertLinkStylemethod with support for all link formats:markdown: Standard[text](url)formatcombined: Combined[@url](url)formatclaude: Claude import@urlformatwikilink: Obsidian[[url]]formatAdded link style detection to determine current format and avoid double-conversion
Added proper AST manipulation for each conversion type with appropriate node transformations
Added conversion validation to only convert internal links and prevent unnecessary changes
Implementation Details
detectCurrentLinkStyle(): Identifies current link format based on text content and node structureconvertToCombined(): Converts standard markdown to combined format[@url](url)convertToClaude(): Converts to Claude import format@urlconvertToWikilink(): Converts to Obsidian wikilink format[[url]]convertToMarkdown(): Converts back to standard markdown formatTesting
✅ Before Fix:
$ markmv convert test.md --link-style combined --verbose No changes needed in test.md Files modified: 0✅ After Fix:
$ markmv convert test.md --link-style combined --verbose Converted 4 links in test.md Files modified: 1✅ Conversion Example:
✅ No Double-Conversion:
Running the same command twice correctly reports "No changes needed" on the second run.
Breaking Changes
None - this fixes existing functionality without changing the API.
