* lisp/startup.el (normal-top-level): Do not put "." after "/";
it’s not needed and with current file-name-as-directory it does
the wrong thing if PWD is a symlink.
* lisp/startup.el (normal-top-level): Also delete PWD if
file-attributes fails for either $PWD or default-directory,
instead of failing out of the top level.
This fixes a regression from Emacs 26 (Bug#42903).
* doc/emacs/custom.texi (Find Init): Update description of how Emacs
finds its init file directory and the interaction with
$XDG_CONFIG_HOME
(Early Init File): Correct XDG location of early-init.el
* etc/NEWS: Update description to make it clear the ~/.emacs.d is
preferred, even if the XDG location exists.
* lisp/startup.el: Prefer ~/.emacs.d even if the XDG location exists.
* lib-src/emacsclient.c (open_config): Prefer home directory the XDG
location.
* lisp/progmodes/elisp-mode.el (lisp-interaction-mode):
Set lexical-binding.
* lisp/startup.el (command-line, startup--get-buffer-create-scratch):
Don't set lexical-binding here.
* doc/lispref/variables.texi:
* etc/NEWS:
Make it clear that lisp-interaction-mode uses lexical-binding.
* lisp/emacs-lisp/package.el (package--activated): New variable to
avoid changing value of defcustom 'package-enable-at-startup'.
(package-initialize): Don't set 'package-enable-at-startup'.
(package-initialize, package-activate-all): Set 'package--activated'
instead of 'package-enable-at-startup'.
(package--initialized): Add doc string.
* lisp/startup.el (command-line): Check if 'package--activated' is
non-nil before activating packages.
* doc/lispref/package.texi (Packaging Basics): Update docs.
* lisp/startup.el (x-apply-session-resources): Enable tab-bar-mode
when X resource "tabBar" class "TabBar" is "on", "yes" or "1".
* doc/man/emacs.1.in:
* doc/emacs/xresources.texi (Table of Resources):
Document X resource "tabBar" (class "TabBar").
* lisp/startup.el (fancy-about-text, normal-about-screen): Clarify
that "Contribute" also describes how to report bugs. Add new link
"Emacs Manual". (Bug#20697)
Problem reported by Katsumi Yamaoka (Bug#37456).
* lisp/startup.el (startup--xdg-or-homedot): Also
prefer .emacs.d if a traditional .emacs file exists.
Problem reported by Glenn Morris (Bug#583#56).
* lisp/startup.el (startup--xdg-config-default): New constant.
(startup--xdg-config-home-emacs): New var.
(startup--xdg-or-homedot): New function.
(normal-top-level): Use it to set user-emacs-directory early on.
(command-line): Also use it to determine the startup init directory.
* lisp/subr.el (user-emacs-directory): Just initialize to nil.
That way, when Emacs starts in a fresh home directory,
it prefers the new (XDG) convention rather than the old one.
* lisp/files.el (locate-user-emacs-file): Make the parent
directories of user-emacs-directory if needed. This is useful
if user-emacs-directory is "~/.config/emacs" and "~/.config"
does not yet exist.
* lisp/startup.el (command-line):
* lisp/subr.el (user-emacs-directory):
Prefer XDG_CONFIG_HOME to ~/.emacs.d if neither exists.
Fit in better with the XDG conventions.
Something like this was suggested in 2008 (Bug#583)
and the XDG conventions seem to have settled down by now.
* doc/emacs/custom.texi (Init File, Init Syntax, Find Init):
* doc/lispref/files.texi (Standard File Names):
* doc/lispref/os.texi (Init File):
* doc/misc/url.texi (Customization):
* etc/NEWS:
Adjust accordingly.
* lisp/startup.el (startup--load-user-init-file):
If init-file-name is nil, do not load from it; instead
just use the alt-file.
(find-init-path): Remove; no longer used.
(command-line): Don't check twice for XDG.
Look at XDG_CONFIG_HOME instead of assuming it's ~/.config.
Prefer XDG configuration if it exists; the user can disable
this by setting XDG_CONFIG_HOME to some other place.
* lisp/subr.el (user-emacs-directory):
Prefer XDG configuration if it exists.
Say that pdumping cannot redump unless -batch is used. Say that
the traditional unexec dumping method is by default not available,
and is deprecated. Don't call dump files "portable", as dump files
are not any more portable than the Emacs executables themselves.
Just call them "dump files". Similar, prefer "portable dumper"
(since the dumper code is portable) to "portable dumping" (since
the dump file is not). Be more systematic about calling them
"dump files" instead of "dumped images" or whatnot.
Restore lines saying "Maintainer: emacs-devel@gnu.org" when there is
no special maintainer for a file. Although this wasn't documented
it was common practice and removing the lines didn't have consensus.
* lisp/startup.el (command-line): Default to lexical-binding in *scratch*.
(normal-no-mouse-startup-screen, command-line-1):
Use startup--get-buffer-create-scratch.
(command-line-1):
* lisp/simple.el (eval-expression):
* lisp/server.el (server-eval-and-print): Use lexical-binding to
evaluate the expression.
