Refine 'Update with bibliographic information' logic (Fixes #14185)

[kammari-ashritha]

Closes #14185

I implemented the logic to update bibliographic information using entry data (Title/Author) via the MultiMergeEntriesView. This adds a new action to the "Lookup" menu and renames the existing identifier-based action for clarity.

Steps to test

1. Create a new entry with only a Title and Author (e.g., Title: Attention is All You Need, Author: Vaswani).
2. Select the entry in the main table.
3. Go to Lookup -> Update with bibliographic information from the web via entry data.
4. The merge dialog should appear with fetched data.

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
Possible issue	✅ Disable action for multiple selections Suggestion Impact: The commit directly implements the suggestion by adding the import for ActionHelper (line 5) and binding the executable property to needsEntriesSelected(1, stateManager) in the constructor (line 14). This ensures the action is only enabled when exactly one entry is selected. code diff: +import org.jabref.gui.actions.ActionHelper; import org.jabref.gui.actions.SimpleCommand; import org.jabref.gui.mergeentries.multiwaymerge.MultiMergeEntriesView; import org.jabref.gui.preferences.GuiPreferences; @@ -25,6 +26,8 @@ this.dialogService = dialogService; this.preferences = preferences; this.taskExecutor = taskExecutor; + + this.executableProperty().bind(ActionHelper.needsEntriesSelected(1, stateManager)); Disable the action if more than one entry is selected. This can be done by binding the executable property in the constructor to only allow execution when exactly one entry is selected. jabgui/src/main/java/org/jabref/gui/importer/actions/UpdateWithWebInfoAction.java [13-36] + import org.jabref.gui.actions.ActionHelper; + public class UpdateWithWebInfoAction extends SimpleCommand { private final StateManager stateManager; private final DialogService dialogService; private final GuiPreferences preferences; private final TaskExecutor taskExecutor; public UpdateWithWebInfoAction(StateManager stateManager, DialogService dialogService, GuiPreferences preferences, TaskExecutor taskExecutor) { this.stateManager = stateManager; this.dialogService = dialogService; this.preferences = preferences; this.taskExecutor = taskExecutor; + + this.executable.bind(ActionHelper.needsEntriesSelected(1, stateManager)); } @Override public void execute() { - if (stateManager.getActiveDatabase().isEmpty() || stateManager.getSelectedEntries().isEmpty()) { + // The check for isEmpty() is still useful as a safeguard, even with the executable binding. + if (stateManager.getSelectedEntries().isEmpty()) { return; } BibEntry selectedEntry = stateManager.getSelectedEntries().get(0); ... -``` [To ensure code accuracy, apply this suggestion manually] Suggestion importance[1-10]: 7 __ Why: The suggestion correctly identifies that the action silently operates on only the first of multiple selected entries, which is poor usability. Binding the action's executability to a single selection is a significant improvement for user experience.	Medium
General	Log exceptions from web fetchers Log the FetcherException instead of silently ignoring it. This will aid in debugging when a web fetcher fails to retrieve information. jabgui/src/main/java/org/jabref/gui/importer/actions/UpdateWithWebInfoAction.java [51-59] + private static final org.slf4j.Logger LOGGER = org.slf4j.LoggerFactory.getLogger(UpdateWithWebInfoAction.class); + + ... + for (var fetcher : fetchers) { mergeView.addSource(fetcher.getName(), () -> { try { return fetcher.performSearch(selectedEntry).stream().findFirst().orElse(null); } catch (FetcherException e) { + LOGGER.warn("Failed to fetch information for entry {} using fetcher {}", selectedEntry.getCitationKey().orElse("<no key>"), fetcher.getName(), e); return null; } }); } -``` [To ensure code accuracy, apply this suggestion manually] Suggestion importance[1-10]: 6 __ Why: The suggestion correctly points out that silently catching the FetcherException is bad practice. Logging the exception improves maintainability and debuggability by providing insights into why a fetcher might have failed.	Low

Please go through the checklist and either finish the TODO or mark it as n/a. See the temple.

Nice. Next time do it straight from the beginning!

[kammari-ashritha]

Understood. I will ensure to follow the guidelines strictly from the start in future contributions. Thanks for your patience.

[kammari-ashritha]

@koppor I have updated the code to use the executableProperty binding as requested.

The Unit Tests and Binaries are all passing (Green). The JBang failures seem unrelated to my changes in UpdateWithWebInfoAction.java.

Ready for final review!

[kammari-ashritha]

@koppor Thank you for the review. I have refactored the code to use getFirst() and wrapped the source name in Localization.lang("Original") to ensure proper translation support. Ready for merge.

PR was more than 800 commits behind main. WHY?

[kammari-ashritha]

@koppor I have removed var and used explicit types (Set). I also added the missing Original=Original key to JabRef_en.properties to fix the localization test.

I am fully committed to completing this task correctly. Ready for review.

[jabref-machine]

You committed your code on the main brach of your fork. This is a bad practice. The right way is to branch out from main, work on your patch/feature in that new branch, and then get that branch merged via the pull request (see GitHub flow).

For this pull request, this is OK. For subsequent pull requests, please start with a different branch with a proper branch name. See CONTRIBUTING.md for more details.

[ZiadAbdElFatah]

@koppor I tried the application using this pr, and found that the logic is ok. Some comments in the code seem suspicious, and you commented on them here #14947 (comment).
It's the first time for me to know that there is no var in JabRef.
I can see now that this issue is about to be closed so should I look for a new one or you want me to do anything in this issue before moving on to a new one ?

[jabref-machine]

Hey, we noticed that you force-pushed your changes. Force pushing is a bad practice when working together on a project (mainly because it is not supported well by GitHub itself). Commits are lost and comments on commits lose their context, thus making it harder to review changes.

When the pull request is getting integrated into main, all commits will be squashed anyway. Thus, your individual commit history will not be visible in main.

In future, please avoid that. For now, you can continue working.

[jabref-machine]

JUnit tests of jablib are failing. You can see which checks are failing by locating the box "Some checks were not successful" on the pull request page. To see the test output, locate "Source Code Tests / Unit tests (pull_request)" and click on it.

You can then run these tests in IntelliJ to reproduce the failing tests locally. We offer a quick test running howto in the section Final build system checks in our setup guide.

[koppor]

It's the first time for me to know that there is no var in JabRef.

Comes with more code reading.

What you could have seen that a CHANGELOG.md is missing.

[ZiadAbdElFatah]

Yeah that is true.
I am glad that you gave me the opportunity to review some code, and hope to get better in reviewing codes in the future.

[koppor]

@ZiadAbdElFatah Can you re-create the PR? I think, you are using AI more properly than @kammari-ashritha . I am not patient enough to comment again.

[koppor]

@kammari-ashritha At first, your PR looked promising, but then it lost quality.

• Menu item not available in JabRef
• No CHANGELOG.md entry

I cannot work on that basis. The PR makes the impression, you are guiding an AI, but not checking its result.

[ZiadAbdElFatah]

@ZiadAbdElFatah Can you re-create the PR? I think, you are using AI more properly than @kammari-ashritha . I am not patient enough to comment again.

Ok sure.

[koppor]

@kammari-ashritha You can try another issue if you want.
