[SOLVED]: Two issues : when invoking `treemacs` and icon display

[zenny]

Bonjour @abougouffa,

I came across this repo from your reddit reply in https://www.reddit.com/r/emacs/comments/12byp43/testing_different_emacs_distros_easy_way_in_emacs/. Excellent configs!

However, I came across two issues:

1. The icons on the right of the modeline are garbled characters.

2. When I run treemacs I get the following error:

Debugger entered--Lisp error: (error "Invalid image type ‘svg’")
  signal(error ("Invalid image type ‘svg’"))
  error("Invalid image type `%s'" svg)
  image-type("/home/zenny/Downloads/..." svg nil)

Merçi beaucoup!

Hello @zenny , thank you for the feedback!

1. The icons on the right of the modeline are garbled characters.

For the icons, you need to run M-x nerd-icons-install-fonts for the first time. This should fix the icons.

2. When I run treemacs I get the following error:

What version of Emacs you are using?

Yes, indeed. Thanks!

2. When I run treemacs I get the following error:

What version of Emacs you are using?

Emacs 30.0.50 from master (from https://github.com/emacs-ng/emacs-ng)

Compiled with:

./configure --with-native-compilation=aot --with-rsvg

Thanks!

I've never tested Emacs-NG! I have no idea what can cause this!

Can you launch Emacs with:

MINEMACS_DEBUG=1 emacs

And share the errors' backtrace?

[zenny]

I've never tested Emacs-NG! I have no idea what can cause this!

Tried with normal emacs 29 as well as emacs 30.0.50 compiled from gnu source, and the output is the same (see below), fyi.

Can you launch Emacs with:

MINEMACS_DEBUG=1 emacs

And share the errors' backtrace?

There is no difference between the error output from emacs --debug-init and MINEMACS_DEBUG=1 emacs, yet I am sharing the output with the latter:

Thanks for looking into. Cheers,

Thank you for the feedback,

There is no difference between the error output from emacs --debug-init and MINEMACS_DEBUG=1 emacs, yet I am sharing the output with the latter:

Yep, it is practically the same, adding --debug-init to Emacs is equivalent to using the MINEMACS_DEBUG environment variable.

Can you share your minemacs-modules ?

Everything is verbatim as yours, no changes, fyi. Yet I list here:

$ ls modules
extras        me-calendar.el  me-debug.el   me-email.el     me-fun.el        me-lisp.el   me-modeling.el       me-org.el      me-rss.el    me-undo.el

No, not the content of modules directory. You need to evaluate the minemacs-modules variable and see the content of that list. I want to verify that the me-files module is enabled, as it is the module which contains the treemacs configuration.

I evaluated the region:

;; Load the default list of enabled modules (`minemacs-modules' and `minemacs-core-modules')
  (+load minemacs-core-dir "me-modules.el")

which gave the following output in the Messages:

Loading /home/zenny/Downloads/emacs-configs/ihsec/minemacs/core/me-modules.el (source)...done
pixel-scroll-precision-scroll-up: Beginning of bufferWarning: setting attribute ‘:background’ of face ‘font-lock-comment-face’: nil value is invalid, use ‘unspecified’ instead.
Warning: setting attribute ‘:background’ of face ‘font-lock-comment-face’: nil value is invalid, use ‘unspecified’ instead. [9 times]

There is no need to evaluate any region. I want just to see the content of the minemacs-modules variable. So you need just to type SPC ; then type minemacs-modules then RET. It should print the content of the list to the *Messages* buffer. That's what I want!

The output of SPC ; minemacs-modules is:

The me-files module is active. I didn't manage to reproduce this on Emacs 29 and 28 error on any of my machines!

Maybe it is emacs 30 specific!

[abougouffa]

I stopped testing the config on Emacs 30, it is unstable and I faced several issues on Emacs 30 builds. I prefer staying on 29 as there is no significant features in 30 compared to 29.

You are absolutely right. I recompiled emacs 29 from upstream and treemacs works with your configuration. Thanks for sharing an interesting config.

Au revoir!
