Thanks for your support João!


I'm gently and slowly tapping into it.


I noticed some recent changes on flymake and eglot though, It looks like
Eldoc started failing me when using it with Eglot.


To reproduce:


Create a =test.ts= file with the content:


#+BEGIN_SRC typescript
  const xxx = 1 ++ 2;
#+END_SRC


Start Emacs compiled from master with:


#+BEGIN_SRC bash
emacs -Q test.ts \
  --eval "(progn \
    (typescript-ts-mode) \
    (setq flymake-show-diagnostics-at-end-of-line t) \
    (eglot-ensure))"
#+END_SRC


Both 1 and 2 are correctly marked with errors, the flymake inline
diagnostic also correctly prints the error inside the buffer.


Problem is that when I position my cursor over the error, or try to run
=flymake-show-buffer-diagnostics=, I always get an error like:


#+BEGIN_SRC bash
flymake--tabulated-setup-1: Wrong type argument: listp, 2357
eldoc error: (wrong-type-argument sequencep 2357)
#+END_SRC


This wasn't the case with my last week build, where eldoc was properly
showing documentation.
