lsp-java VS dumb-jump

lsp-java mode should handle most of that: https://emacs-lsp.github.io/lsp-java/

Speed of Emacs on Java codebases can be faster than IDEA? With features of lsp-java ? How could it possible~~

I dunno about the netbeans LSP server but I use eclipse JDT language server from Emacs and it works pretty well https://github.com/emacs-lsp/lsp-java

According to lsp-java, variable lsp-java-format-settings-url specifies the url or file path to the eclipse formatter xml settings. This file eclipse-java-google-style.xml works fine in vscode and eclipse. The expected behavior is line longer than 100 is splited to a new line. In spacemacs, split length is still the default 120.

I see that I can configure DAP mode for a new server. This references "java", which I assume points it to dap-java.el within lsp-java.

You should check out emacs-lsp/lsp-java, it's exactly what you want.

Unfortunately I don't use snippets for the settings, but this must be configurable by the client LSP I've already seen people who can do this kind of thing with lsp-java, I wouldn't be surprised if you can also do it with lsp-python.

TLDW It describes the dumb-jump emacs package: https://github.com/jacktasia/dumb-jump

I use lsp for C++, but for jump to definition I like dumb jump, because it works.

Oh, I forgot to mention, I have also found dumb-jump to work pretty well for Xcode projects, with no configuration.

I don't really have any trouble using Emacs on the "modern" C++ codebases that I'm working on. I've tried lsp-mode and eglot with clangd but found that really all I need is a little bit of elisp to call clang-format, dumb-jump (<https://github.com/jacktasia/dumb-jump>) to jump to definition, and project-compile to build the project and collect warnings/errors into a buffer.

> 2. No language server (apparently it's just impossible due to the way the language works). Tbh, I'd be happy with just "Go to definition" but alas, no-can-do!

Emacs' dumb-jump appears to have some basic support for go to definition: https://github.com/jacktasia/dumb-jump/blob/master/dumb-jump...

But out of curiosity, what is the issue from a technical point of view?

For jumping between function definitions I use dumb-jump, which usually just works. I configure dumb-jump to use ag for its searching which makes it work very quickly.

Mark ring may be what you want. If you want to jump around a code base, Dumb Jump is great: https://github.com/jacktasia/dumb-jump

dumb-jump: another tool based on ripgrep, this one defines regexes for what definitions look like in a bunch of languages. This gives you a primitive jump-to-def functionality without any setup (except installing ripgrep). The pros and cons are roughly the same as rg.el and deadgrep: you might not jump to exactly the thing you want (if there are multiple choices, you can select the definition you prefer), but it requires no setup and is pretty fast.

I recommend https://github.com/jacktasia/dumb-jump

While I have no idea about tags, I want to say that you may find something as simple as dumb-jump[1] does what you want most of the time.
