Comment Handling

This plugin attempts to find the original location of a comment and reattach it. If it cannot determine the correct location, it will add a section to the bottom of the page and place the comment there.

Comment Matching Process

No matches found

If no matches for the text the comment was attached to are found, the comment is moved to the unmatched comment section.

Exact Match

The plugin first tries to find an exact match for the comment by comparing the text before and after the comment. If an exact match is found, the comment is attached at that location.

Distance of whole before and after

If an exact match is not found, the plugin calculates the "distance" between the text before and after the comment in the original location and each potential new location. This distance is calculated using the Levenshtein distance algorithm, which measures the number of changes (insertions, deletions, or substitutions) required to transform one string into another. If there are more than 40 changes before and after the comment text the node is excluded from being a viable option. The potential matches are sorted based on the calculated distances, and the match with the smallest distance is chosen.

Distance of 2 words before and after

If there are still multiple matches with similar distances, the plugin narrows down the selection by comparing only the words immediately surrounding the comment. The Levenshtein distance is calculated again, and the best match is chosen based on the smallest distance.

No ability to match

If no suitable match is found, the function returns undefined.
