2 years ago FYI, I have made the following changes to my config to modify the HCL indentation behavior to only modify the buffer if it needs to. This seems to have addressed the issue. Happy to raise a PR if you like.
(use-package terraform-mode
:hook
(terraform-mode . (lambda () (setq-local indent-line-function 'my/hcl-indent-line))))
(defun my/hcl--maybe-indent-line (column)
"Indent current line to COLUMN if required."
(let ((curcol (- (point) (line-beginning-position))))
(unless (= curcol column)
(delete-region (line-beginning-position) (point))
(indent-to column))))
(defun my/hcl-indent-line ()
"Indent current line as HCL configuration."
(interactive)
(let* ((curpoint (point))
(pos (- (point-max) curpoint)))
(back-to-indentation)
(if (hcl--in-string-or-comment-p)
(goto-char curpoint)
(let ((block-indentation (hcl--block-indentation)))
(if block-indentation
(if (looking-at "[]}]")
(my/hcl--maybe-indent-line block-indentation)
(my/hcl--maybe-indent-line (+ block-indentation hcl-indent-level)))
(my/hcl--maybe-indent-line (hcl--previous-indentation)))
(when (> (- (point-max) pos) (point))
(goto-char (- (point-max) pos)))))))
Hi-Angel
The function
hcl-indent-lineis called when TAB is pressed via Emacs'indent-for-tab-command. Even when no indentation changes are required,hcl-indent-linemodifies the buffer by callingdelete-region(here) and then re-adding the indentation. This has the side-effect of modifying the buffer's tick count whichindent-for-tab-commandinspects (here) to determine whether or not to callcompletion-at-point. Becauseindent-for-tab-commandthinks that the buffer has changed every time TAB is pressed it never callscompletion-at-pointwhich has the effect of breaking the completion system.
