I want to view Java documentation like https://docs.oracle.com/en/java/ inside emacs.
I have tried lsp-java with lsp-ui but my setup wasn't enough.

Have you read the documentation for lsp-ui yet? When you do, you will find a quick summary of the features in the README file. This includes information about lsp-ui-doc, with nice screenshots of the several ways that it can show the documentation. It also includes a short list of variables that you can customize. First amongst these is lsp-ui-doc-enable, which does exactly what you think it does. Use M-x customize-variable to toggle it. You can use M-x customize-group to customize the lsp-ui-doc group, which will show you all of the variables it uses.

Yes I have read (default value of
lsp-ui-doc-enableis t). The problem is that for a a simpleSystem.out.println(...)onlyvoid java.io.PrintStream.println(...)is shown, not a full documentation of the behavior of the method.Francesco Cadei– Francesco Cadei2023-10-18 08:36:20 +00:00Commented Oct 18, 2023 at 8:36 -
