[GSOC22] - B - Implement merging fields in the three way merge UI #9022

HoussemNasri · 2022-08-03T21:48:15Z

Closes #8024
Depends on #8945
Contributes to #6190

It appears that every time a field changes, an event bus marks the library as edited. The library will remain marked as edited even after I undo groups merging and cancel the merge dialog. Right now, I can't think of a way to fix this.

Edit
Keywords and Comments can be merged too.

Tests created for changes (if applicable)
Manually tested changed features in running JabRef (always required)
Screenshots added in PR description (for UI changes)
Checked developer's documentation: Is the information available and up to date? If not, I outlined it in this pull request.

- Thus commands can be moved to the view model

- Removed FieldNameCellFactory.java and MergeableFieldCell.java - Made it easier to add more side buttons in the future

- Initialized the change name column - Commented out 'getDialogPane().setContent(pane)' because it will be removed later

- Changes are applied only when all changes are resolved (changes table is empty). Like a transaction

Why don't you use the JabRefAction together with the ActionFactory ? It should already cover the cases

I'm not sure how that would work. The idea behind the builder and ActionImpl is to create instances of org.jabref.gui.actions.Action without implementing it; which can be very verbose.

Well, you could either use them as anonymous classes or as separate classes. The latter is probably useful if you are reusing them in multiple placess.

Use a switch here?

And also some parts use == other use equal

I couldn't use a switch expression because Field is an interface. When I changed the type of the parameter to StandardField, it compiled fine but other parts of the codebase broke.

Ah okay, yeah I see. Then field is the correct approach

Not sure, but maybe you should use KeywordList ? This is relevant for keyword groups

You can test if you can inject it as field here or in the caller component and pass it to this component in the constructor
@Inject private PreferencesService preferencesService

It throws a null pointer exception. I think this is happening because the injection is handled by mvvmfx but ThreeWayMergeView doesn't use a view loader. I thought that because @Inject is used in other classes and all of them also use view loader.

You need to inject it into DuplicateResolverDialog

And also pass it from the ChangeScanner -> EntryChangeViewModel -> ThreeWayMergeView via constructor

Here you can use things with @Inject e.g @Inject PreferencesService preferencesService; and pass that to other

Injection doesn't work here either

overall looks good to me just a few minor improvements

We are thinking of merging this so the early bird users can the new feature, Can PR A and B be merged?

PR A is complete. This one still needs some nitpicks, but it should be ready today or tomorrow.
