Added CiteFormatter and BibLatexFormatter for CAYW feature #13704

Tushar2604 · 2025-08-16T13:43:41Z

This PR extends the Cite-As-You-Write (CAYW) feature in JabRef to fully comply with the formats supported by Better BibTeX.

New supported formats:

natbib
latex
citep
mmd
pandoc
typst

Steps to test

Start JabRef with the server enabled: "./gradlew clean run"
Run the tests : "./gradlew :jabsrv:test"
verify that the following formats are now supported in addition to the existing ones:

natbib → should return \citep{key} style output

latex → should return \cite{key} style output

citep → explicitly handled citation with \citep{key}

mmd (MultiMarkdown) → should return [#key] style citations

pandoc → should return [key] style citations

typst → should return [key] style citations

Confirm all tests pass and JabRef doesn’t throw any errors when these formats are requested

PR description? steps to test?

subhramit · 2025-08-16T14:31:03Z

Why is this not a draft pr if the build is failing?

Tushar2604 · 2025-08-16T15:20:32Z

Sorry it was mistake. I will be redoing this .Sorry for the inconvenience.

jabsrv/src/main/java/org/jabref/http/server/cayw/format/CiteFormatter.java

+    public String format(CAYWQueryParams queryParams, List<CAYWEntry> cawEntries) {
+        String command = queryParams.getCommand();
+        if (command == null || command.isBlank()) {
+            command = "citep"; // default for citep


The comment 'default for citep' is redundant and does not provide any additional information beyond what is clearly visible in the code itself.

jabref-machine · 2025-08-16T15:23:38Z

Your code currently does not meet JabRef's code guidelines. We use Checkstyle to identify issues. 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 / Checkstyle (pull_request)" and click on it.

In case of issues with the import order, double check that you activated Auto Import. You can trigger fixing imports by pressing Ctrl+Alt+O to trigger Optimize Imports.

Please carefully follow the setup guide for the codestyle. Afterwards, please run checkstyle locally and fix the issues, commit, and push.

Sorry it was mistake. I will be redoing this .Sorry for the inconvenience.

No need for re-do. Just edit PR description and push new commits. You can also change to draft at GitHub's UI.

jabref-machine · 2025-08-19T14:56:59Z

Note that your PR will not be reviewed/accepted until you have gone through the mandatory checks in the description and marked each of them them exactly in the format of [x] (done), [ ] (not done yet) or [/] (not applicable).

JUnit tests of jabsrv 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.

Empty string is used as a fallback for missing citation keys, which could lead to invalid LaTeX syntax. Should handle this case more explicitly or throw an exception.

+                                               .toList();


This intermediate list creation is unnecessary since the stream is used immediately after. The operations can be chained directly for better performance.

The comment is trivial and only restates what is obvious from the code itself. Comments should add new information or reasoning that cannot be derived directly from the code.

+        } else {
+            // Default: bare @key format with semicolon separator


The comment merely describes what the code does without providing additional context or reasoning. Such trivial comments should be removed as they don't add value beyond what's visible in the code.

Variable name 'qp' is too short and doesn't convey meaning. Variable names should be descriptive and include intention in their naming.

Using assertFalse to check collection emptiness is less specific than directly asserting the contents. Use assertions that provide better failure messages and more precise validation.

Using assertTrue for size comparison is less descriptive than assertThat or assertEquals. The test should assert the actual contents of the collection rather than a boolean condition.

From what can be gathered from your code, the impression is that you do not know what these formats are, what JabRef is or even what a Bibtex entry is.
The code is heavily AI-generated.

Furthermore, due to insincerity in marking the mandatory checks:

(None of the commits so far have a passing build check - so I don't know how you manually tested)
I am inclined to close the PR.
Please gather some context about the project you are contributing to, read the devdocs on setting up a local workspace, look at some existing tests and maybe then take up an issue.

Siedlerchr · 2025-08-25T17:51:17Z

You don't seem to have any idea and just rely on AI. Thus closing
