Re: source blocks mangled when edited

[Samuel Wales <samologist@gmail.com>]

idk if this will help as you probably know all of it already.  butg
you asked for any help so here goes.  i run maint, not master or any
emacs versions.  weird that you are missing 3 cols?

===

here are notes on my workaround which wfm in the meantime if you are
willing to do the same thing.  i was having trouble getting exported
indentation for example blocks.

;; fix default for source and example block indentation
;;
;; when you edit a source or data block, org will by default
;; remove some leading whitespace and then add 2 spaces, so the
;; whole block in org is indented by 2.
;;
;; (the deleted rectangle seems to be the maximum amount of
;; whitespace common to all lines in each block.)
;;
;; initial tabs get converted to spaces.  example blocks get
;; unindented during export incorrectly.  mistakes are possible.
;; this as non-nil prevents all that.  see led for more.
;;
;; we EITHER unindent all and set this non-nil, OR put up with
;; stripping of leading whitespace from blocks where we don't
;; want the indentation stripped.
;;
;; /i prefer t./ it is not possible in babel to indent without
;; having the special feature of removing the whitespace
;; rectangle.
;;
;; you can use -i to locally do t.  there isn't an arg that
;; locally does the reverse of -i.  i.e. to do nil.
;;
;; i have gotten comfortable with no indentation and imo it is a good
default for newcomers and does not surprise.
;;
;; source blocks might actually work without indentation even
;; with the default value, but then when you edit it indents.
(setq org-src-preserve-indentation t)
;; (setq org-src-preserve-indentation nil)
;;
;; only has effect if org-src-preserve-indentation is nil
;; (setq org-edit-src-content-indentation 0)
