eslint-flymake VS dap-mode

> Why wouldn't you want the lint error to be highlighted right as you type the code?

Why do you think you need to involve an LSP for that?. ESLint, as most linters, can take their input from stdin. That is exactly how the eslint-flymake[0] works. Lint on buffer contents, not file on disk. No JSON RPC involved.

Why would there be a canonical list given the fact that anyone can publish a package outside of Emacs core? Who would be in charge of maintaining it? From what I've seen there isn't many backends for the new API but writing your own is straightforward https://github.com/emacs-pe/eslint-flymake. Which languages/linters do you care about?

GDB with gdb -i dap allows you to debug any language that GDB can debug from within Emacs' dap-mode: https://github.com/emacs-lsp/dap-mode

lsp's brother. One search away. https://github.com/emacs-lsp/dap-mode

Debug template for go subtest was just added: https://github.com/emacs-lsp/dap-mode/pull/704/

Debugging (kind of an IDE feature) is a little harder. Out of the box, Emacs can at least debug emacs-lisp (with built-in features) and C (via gdb integration). Beyond that, take a look at dap-mode for other language options. Similarly, take a look at lsp-mode or eglot for code completion, more advanced linting, etc.

At least for web development I believe eglot is strictly worse. It does not support running multiple servers (e.g. tsserver and eslint-ls) (https://github.com/joaotavora/eglot/issues/976) which is supported by lsp-mode and neovim's built-in lsp client. Also, it does not have any equivalent to dap-mode which is lsp-mode only. Although worth noting dap-mode is currently useless for js (https://github.com/emacs-lsp/dap-mode/issues/369).

Hi, as it seems EGlot will receive the blessing of inclusion into vanilla Emacs. That makes me wonder how I am supposed to use dap-mode at it swaps in lsp-mode as a dependency.

We will use dap-mode with the dap-gdb-lldb option here. Under the hood, it uses the debug adapter from the Native Debug VSCode extension. Configuring it is described on the dap-mode webpages. After we have configured dap-mode, we could in theory reuse the launch.json configurations from the VSCode related articles above. That will require that you also use lsp-mode, as dap-launch depends on the lsp-workspace-root function and will not resolve when lsp-mode is not used. I don't use lsp-mode with C (company-clang and company-c-headers provide what I need), so the next logical solution would be to create a debug template ourselves:

Hmm it does seem like Emacs is growing support for the Debug Adapter Protocol (DAP), the LSP-alike convention that allows language developers to build language-specific debuggers that tie into the VSCode UI: https://github.com/emacs-lsp/dap-mode

So, what do you need: - Language server for Python (lsp and lsp-ui) Use lsp-mode it's more reach with features at the moment https://emacs-lsp.github.io/lsp-mode/page/installation/ - Real-time program debugging (dap-mode) https://github.com/emacs-lsp/dap-mode

Seems like too much work and the issue has been closed and not reopened since 2018 sadly. It looks like it won't be happening any time soon. https://github.com/emacs-lsp/dap-mode/issues/2
