- Adds a per-library "Duplicate Items" virtual search to the source list -- shows up by default for "My Library" but can be added to and removed from all libraries
- Current matching algorithm is very basic: finds exact title matches (after normalizing case/diacritics/punctuation/spacing) and DOI/ISBN matches (untested)
- In duplicates view, sets are selected automatically; in other views, duplicate items can be selected manually and the merge interface can be brought up with "Merge Items" in the context menu
- Can select a master item and individual fields to merge from other versions
- Word processor integration code will automatically find mapped replacements and update documents with new item keys
Possible future improvements:
- Improved detection algorithms
- UI tweaks
- Currently if any items differ, all available versions will be shown as master item options, even if only one item is different; probably the earliest equivalent item should be shown for each distinct version
- Caching of results for performance
- Confidence scale
- Creator version selection (currently the creators from the chosen master item are kept)
- Merging of matching child items
- Better sorting of duplicates if not clustered together by the selected sort column
- Relation path compression when merging items that are already mapped to previously removed duplicates
Other changes in this commit:
- Don't show Trash in word processor integration windows
- Consider items in trash to be missing in word processor documents
- Selection of special views (Trash, Unfiled, Duplicates) is now restored properly in new windows
- Disabled field transform context menu when item isn't editable
- Left/right arrow now expands/collapses all selected items instead of just the last-selected row
- Relation deletions are now synced
- The same items row is now reselected after item deletion
- (dev) Zotero.Item.getNotes(), Zotero.Item.getAttachments(), and Zotero.Item.getTags() now return empty arrays rather than FALSE if no matches -- tests on those return values in third-party code will need to be changed
- (dev) New function Zotero.Utilities.removeDiacritics(str, lowercaseOnly) -- could be used to generate ASCII BibTeX keys
- (dev) New 'tempTable' search condition can take a table to join against -- useful for implementing virtual source lists
- (dev) Significant UI code cleanup
- (dev) Moved all item pane content into itemPane.xul
- Probably various other things
Needless to say, this needs testing.
