[BUG] Tool bar, menu bar and scroll bar are not disabled in emacs 27 (macOS)

[howsiwei]

What did you expect to happen?
Tool bar, menu bar and scroll bar are disabled.

What actually happened?
Tool bar, menu bar and scroll bar are not disabled.

Additional details:
According to the documentation of variable tool-bar-mode,

Setting this variable directly does not take effect;
either customize it (see the info node (emacs)Easy Customization)
or call the function tool-bar-mode.

So I changed

(setq tool-bar-mode nil)

to

(tool-bar-mode 0)

However, it still doesn't work until I move the code from early-init.el to init.el. (Using the setq method in init.el doesn't work.)

Similarly, I removed

(setq menu-bar-mode nil)

in early-init.el
and add

(menu-bar-mode 0)

in init.el.
Finally, I moved

 (when (fboundp 'set-scroll-bar-mode)
   (set-scroll-bar-mode nil))

from early-init.el to init.el to remove the scroll bar.

Is it possible that you installed a version of Emacs 27 before it early-init.el was implemented? These lines are disabled in Emacs 27 because they're redundant with the work done in early-init.el.

Is it possible that you installed a version of Emacs 27 before it early-init.el was implemented?

I don't think so. I installed Emasc 27 with

brew install emacs-plus --with-emacs-27-branch --HEAD --with-jansson --with-modern-icon

and the resulting Emacs is built using commit f0ebd919c16c71d1010f2625425932e46b58f8b4, which is the latest commit on emacs-27 branch with the latest commit committed 13 hours ago.

Also note that the documentation of early init file says that

   We do not recommend that you move into ‘early-init.el’ customizations
that can be left in the normal init files.  That is because the early
init file is read before the GUI is initialized, so customizations
related to GUI features will not work reliably in ‘early-init.el’.  By
contrast, the normal init files are read after the GUI is initialized.
If you must have customizations in the early init file that rely on GUI
features, make them run off hooks provided by the Emacs startup, such as
‘window-setup-hook’ or ‘tty-setup-hook’.  *Note Hooks::.

I understand that. The purpose of those settings were to set them early enough that Emacs won't initialize them when they eventually load. tool-bar-mode is enabled by default, but hasn't been loaded yet in early-init.el. By setting the variable to nil ahead of time, the mode should not be auto-enabled when it is loaded. So unless tool-bar.el.gz is loaded earlier on macOS than it is on Linux (where these lines work properly), it should behave as expected.

I don't have a mac to test on atm. I'll investigate when I get a chance.

[hlissner]

I can't reproduce this. I loaded up two VMs, one in Mojave, one in Catalina. I installed Emacs with:

brew install emacs-plus --with-emacs-27-branch --HEAD --with-jansson --with-modern-icon
git clone https://github.com/hlissner/doom-emacs ~/.emacs.d
~/.emacs.d/bin/doom install
emacs

Emacs opened with the menu bar, tool bar and scroll bars disabled, as intended.

[howsiwei]

@hlissner you're right. After investigation I found out that the bars were not disabled because I was using chemacs which doesn't load the early-init.el file. Without chemacs tool bar and scroll bars are correctly disabled. Menu bar is still enabled but that's the expected behavior in macOS [1].

Just in case anyone else finds this like I did: Chemacs 2 solves the issue as it has support for early_init.el. Works very nicely with Doom.
