And we know that in past people were indenting by using TAB instead of SPACE what is today common. My proposal is that Emacs detects the type of a newly opened file and warns user, similarly to how editor Notepadqq does it: Such detection could trigger following warning and choice dialogue, and this represents possible proposal: 1) This file is indented with spaces, but your current settings specify to use tabs [USE SPACES] [CONTINUE USING TABS] 2) This file is indented with tabs, but your current settings specify to use spaces [USE TABS] [CONTINUE USING SPACES] 3) This file has not been indented by standard Emacs style [IGNORE AND CONTINUE] [USE EMACS INDENTATION STYLE] In GNU Emacs 29.0.50 (build 7, x86_64-pc-linux-gnu, X toolkit, cairo version 1.17.6, Xaw3d scroll bars) of 2022-06-02 built on protected.rcdrun.com Repository revision: 2244dc5ce9f78ecab7232323e8dfeb9e79835b2b Repository branch: master Windowing system distributor 'The X.Org Foundation', version 11.0.12101003 System Description: Parabola GNU/Linux-libre Configured using: 'configure --with-x-toolkit=lucid' Configured features: ACL CAIRO DBUS FREETYPE GIF GLIB GMP GNUTLS GPM GSETTINGS HARFBUZZ JPEG JSON LCMS2 LIBOTF LIBSYSTEMD LIBXML2 M17N_FLT MODULES NOTIFY INOTIFY PDUMPER PNG RSVG SECCOMP SOUND SQLITE3 THREADS TIFF TOOLKIT_SCROLL_BARS WEBP X11 XAW3D XDBE XIM XINPUT2 XPM LUCID ZLIB Important settings: value of $LC_ALL: en_US.UTF-8 value of $LANG: de_DE.UTF-8 value of $XMODIFIERS: @im=exwm-xim locale-coding-system: utf-8-unix Major mode: Lisp Interaction Minor modes in effect: tooltip-mode: t global-eldoc-mode: t eldoc-mode: t show-paren-mode: t electric-indent-mode: t mouse-wheel-mode: t tool-bar-mode: t menu-bar-mode: t file-name-shadow-mode: t global-font-lock-mode: t font-lock-mode: t blink-cursor-mode: t line-number-mode: t indent-tabs-mode: t transient-mark-mode: t auto-composition-mode: t auto-encryption-mode: t auto-compression-mode: t Load-path shadows: /home/data1/protected/Programming/Software/emacs/lisp/vc/vc-mtn hides /home/data1/protected/Programming/Software/emacs/lisp/obsolete/vc-mtn Features: (shadow sort mail-extr emacsbug message mailcap yank-media rmc puny dired dired-loaddefs rfc822 mml mml-sec password-cache epa derived epg rfc6068 epg-config gnus-util text-property-search time-date seq gv subr-x byte-opt bytecomp byte-compile cconv mm-decode mm-bodies mm-encode mail-parse rfc2231 mailabbrev gmm-utils mailheader cl-loaddefs cl-lib sendmail rfc2047 rfc2045 ietf-drums mm-util mail-prsvr mail-utils iso-transl tooltip eldoc paren electric uniquify ediff-hook vc-hooks lisp-float-type elisp-mode mwheel term/x-win x-win term/common-win x-dnd tool-bar dnd fontset image regexp-opt fringe tabulated-list replace newcomment text-mode lisp-mode prog-mode register page tab-bar menu-bar rfn-eshadow isearch easymenu timer select scroll-bar mouse jit-lock font-lock syntax font-core term/tty-colors frame minibuffer nadvice simple cl-generic indonesian philippine cham georgian utf-8-lang misc-lang vietnamese tibetan thai tai-viet lao korean japanese eucjp-ms cp51932 hebrew greek romanian slovak czech european ethiopic indian cyrillic chinese composite emoji-zwj charscript charprop case-table epa-hook jka-cmpr-hook help abbrev obarray oclosure cl-preloaded button loaddefs faces cus-face macroexp files window text-properties overlay sha1 md5 base64 format env code-pages mule custom widget keymap hashtable-print-readable backquote threads dbusbind inotify lcms2 dynamic-setting system-font-setting font-render-setting cairo x-toolkit xinput2 x multi-tty make-network-process emacs) Memory information: ((conses 16 45983 10741) (symbols 48 6254 1) (strings 32 17745 1661) (string-bytes 1 557813) (vectors 16 11212) (vector-slots 8 165045 12405) (floats 8 22 50) (intervals 56 236 5) (buffers 992 11)) -- Thanks, Jean Louis Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns From unknown Sat Jun 14 14:28:11 2025 X-Loop: help-debbugs@gnu.org Subject: bug#55991: 29.0.50;

"new style" -- it is relevant only to such old source files, as Emacs will automatically impose indentation However, old source files shall sometimes remain how they are when opened. There may cultural and habitual reason for the files to remain not indented. When user opens such old file, various modes in Emacs are going to start enforcing the indentation on user. Users should be warned if they should allow Emacs to change even those invisible characters or if they should adopt the new indentation or not when editing such files. For example, instead of TABS, an Emacs mode may start enforcing spaces without asking user. Other editor notepadqq asks user if that change should take place. 1) It is possible to make function to recognize that file had tabs instead of spaces, and user should be asked about it. 2) It is possible to recognize that file was not indented by the mode's standard, and to ask user if new indentation should be adopted.
