eglot sees the whole outer buffer content about polymode

[s-kostyaev]

Same problem with flymake, markdown and emacs lisp with both poly-markdown-mode and poly-gfm-mode without eglot.

As a workaround, I have to edit innermode content in another buffer by edit-indirect, here's my config:

(define-innermode poly-bash-innermode
  :mode 'bash-ts-mode
  :head-matcher "^ *#!/usr/bin/env \\(sh\\|bash\\)\n"
  :tail-matcher "^ *# </bash>$"
  :head-mode 'body
  :tail-mode 'body)

(define-hostmode poly-yaml-ts-hostmode
  :mode 'yaml-ts-mode)
(define-polymode poly-yaml-ts-mode
  :hostmode 'poly-yaml-ts-hostmode
  :innermodes '(poly-bash-innermode))
(add-hook 'yaml-ts-mode-hook 'poly-yaml-ts-mode)

(setq polymode-prefix-key (kbd "s-,"))

(defun my/polymode/edit-chunk ()
  (interactive)
  (call-interactively 'polymode-mark-or-extend-chunk)
  (call-interactively 'edit-indirect-region))
  
(define-key polymode-mode-map (kbd "s-, e") 'my/polymode/edit-chunk)          ; [e]dit by edit-indirect

;; eglot/lsp needs "workspace/file" view, so we set buffer-file-name to a fake path in the same dir as the visiting file
(defun edit-indirect-guess-mode (_parent-buffer _beg _end)
  (setq-local buffer-file-name (format "%s.-ei-" (buffer-file-name _parent-buffer)))
  (funcall (buffer-local-value 'major-mode _parent-buffer)))
(setq edit-indirect-guess-mode-function #'edit-indirect-guess-mode)

I see people are using polymode with lsp-mode in #305 – is this an issue with polymode or with eglot?
