I am running labwc as Wayland compositor on Arch Linux. When I change the fonts, icons, mouse etc. and apply the application shows the correct preview but when I open it again I see the default settings again. Oddly, the gtk3 settings.ini file show the changes instead.

(...) is it possible to have a command-line option to export nwg-look preferences to files? i use nwg-look to set my themes, and on top of that, i have darkman for automatic dark mode toggling. i set my theme to a light one during the day, and a dark one when it's night time, and apps under XWayland reads the gtk settings files instead of directly reading from gsettings, so having a command-line option for nwg-look to automatically export to files would be really neat!

I want to change my Hyprland cursor and was redirected to this repo. There seems to not be any nixpkg of this, so I'm making an issue for it

On your github README the screen shows default font options to choose from, but on the actual software it is missing as well as in the screen that you have on your website
I don't know any other software which could work with font settings under wlroots, so It would be nice to see it back.

I thought it was a good app, but it turned out to be a copy of LXappearance, with the same disease, so I deleted it...

The question is - why are you violating the XDG specification?
Why are you polluting the HOME catalog?

Themes and icons should be here
~/.local/share/icons
~/.local/share/themes

and gtk files should be here
~/.config/gtk-2.0/gtkrc
~/.config/gtk-3.0/settings.ini

The icon folder can be on two locations:

~/.icons
$XDG_DATA_HOME/icons

Can you support both locations?

Hello,

can you support environment variables like the following one?

GTK2_RC_FILES=${XDG_CONFIG_HOME}/gtk-2.0/gtkrc-2.0

Problem

When I try to build nwg-look from source, I get the following

Info

I am on fedora 38. I have go installed (v.1.21.3), gtk3, and glib

Hey bro, first off, I love your projects.

I use mostly your nwg-look which is wayyyy better than any other gtk-settings / theming app in my opinion.

Question:

Do you have any plans on maintaining a COPR repo for our fedora users?

Building from source is kinda takes long tbh and would be nice if there is for Fedora

(oh and maybe Debian) :)

TIA

The code to load data files (en_US.json and main.glade) is hardwired to use /usr/share as the location. This prohibits alternate installation locations (e.g. /usr/local). The getDataDirs() function in tools.go can easily be leveraged to provide a "search path" for locating these files. I will submit a pull request that implements this change for your consideration.

I'd like to suggest xsettings support using xsettingsd, since some xwayland apps I've found, mostly using electron apps, only seem to follow some settings from xsettings. xsettingsd by default uses .xsettingsd. More info about configuring it on their wiki: https://github.com/derat/xsettingsd/wiki/Settings

There is also GNOME's xsettings daemon gsd-xsettings, but I haven't tried it and don't know how it works.

Many cursor themes (such as quintom) do not ship with a index.theme file. Instead, they ship with a cursor.theme file. The syntax is indentical. Some ship with both as well.
As of now, nwg-look seems to only look for the index.theme file, and since the theme didn't have it it didn't show up in the cursor list.

I assume I screwed something up, this used to work just fine.

nwg-look -d

I've tried to install both ngw-look and ngw-look-bin, same results. The en_US.json file seems to exist

sudo find / -iname en_US.json
                                                                                                                                                                                                                        
/home/xxx/.cache/paru/clone/nwg-look-bin/src/langs/en_US.json
/usr/share/nwg-look/langs/en_US.json

Let me know what I could have done to screw this up :(

There should a shortcut to apply sentings by Keyboard.
It could be implemented as when user press Alt Key highlight A for Apply and C for Close.
Hitting Alt+A will apply the settings.

Alt key is used as standard for this function in most other softwares (Firefox,xfce-apps,etc).
So It will be good to have it.

(Currently you need mouse for applying settings which is not so comfortable)

I went a bit too fast whilst installing nwg-look and got the error below. Of course after installing main.glade at the right location this problem went away.

I like to keep track of my config files with git so I would like to know what files nwg-look stores configurations in / is dependant on. Git is also not great at handling binary files so if possible I would like to exclude such files from being versioned (such as dconf files).

What I'm Requesting:

• Documentation for what files need to be versioned in order to be able to restore settings to a similar state with said files. I e I would like to be able to use git to restore my settings after for example a reinstallation.
• If the above mentioned files include binary files (such as dconf files) then I would ideally want a way to export/import those configs in a more human readable and git friendlier text format. But if that functionality is out of scope or hard to implement then I am would be very happy to just have documentation for which settings are stored in that way. That way users can determine for themselves if they want to save save those settings.

It would be awesome if nwg-look could handle gtk-4.

My icon theme is symlinked from one location to ~/.local/share/icons, but it fails to be recognized. If I manually copy it to ~/.local/share/icons, it functions correctly. However, I have specific reasons for preferring to use a symlink. Are there any solutions to this issue?

Hi,

Firstly I'd like to thank you for this project, it's been really helpful in my transition to Wayland.

I've noticed that currently when using nwg-look -a, the text scaling factor is not actually read from the file, and the default is instead used. I've had a go at creating a patch for it (see below), and it seems to work well on my end.

Cheers,
Grzegorz

Is there a way to get nwg-look to work with GTK-4 apps?

i 've installed the pkg so as to correct font issues with some gtk apps on endeavourOS (arch + plasma6) .
It does the job pretty well, but:

1. Why to block the app to create Desktop entry on the user desktop for GNOME;XFCE;MATE;KDE ?
2. in the console i get:

WARN[0000] Unsupported config key: gtk-decoration-layout 
WARN[0000] Unsupported config key: gtk-enable-animations 
WARN[0000] Unsupported config key: gtk-modules

WARN[0000] Unsupported config key: gtk-sound-theme-name 
WARN[0000] Unsupported config key: gtk-xft-dpi 
...
WARN[0018] Couldn't find icons folder ```

3) can you limit the production of GTK config files base on the default path of the major distros

Do you have any plans on getting nwg-look packaged on NixOS? Thanks.

First of all, I would like to thank you for your tireless efforts. I use nwg-shell components in yocto/openembedded build environment and I am really thankful for that tools that enrich wlroots/sway a lot.

Found two small issues:

And if wearing the distributors hat, i'd like to have a LICENSE file to ship with the package

Apart from this i did succeed in building nwg-look for x86-64 and aarch64.

Looks awesome. Great work!

Hello! When I run make build inside the cloned repository, the process gets stuck in github.com/gotk3/gotk3/gtk, and doesn't proceed. I initially tried it with makepkg from the AUR, and when I encountered this error, I tried to build from source by cloning the repository and building it. Both of the attempts resulted in the same thing.

Attempting to set a theme, running Hyprland WM setting WhiteSur theme. Everything applies correctly but the gtk2 file does not get saved. I do have GTK2_RC_FILES defined, idk if thats meant to break the app but it doesnt respect this env either. There are 0 traces of any gtk2 files created on the system.

By constrast, lxappearence did make them. I recently switched from lxappearance to this, because I was recommended it. Any ideas what might be happening?

Greetings. First of all, I'd like to thank you for this very useful software.

I am using nwg-look to change the look of gtk on hyprland. I was using breeze-dark icons and cursor, when I decided to change the cursor to Catppuccin-Mocha-Dark from the AUR. In selecting a different cursor, all icons changed to adwaita (i noticed this on thunar, which is the main gtk program i use), and all my attempts to set a different icon set were for naught, as I seem to be unable to change the icons using nwg-look. I have had to install kde-plasma and make the change there in order to be able to have my old icons with the new cursor.

I'm attaching a video showcasing the issue as well as a log file of the output of nwg-look.

nwg-look.log

Font displays as "None" if the specified font family is different from display name

So, let's say there's 'JetBrainsMono NF SemiBold 12', but there's also 'JetBrainsMono Nerd Font SemiBold 12'
Even though both variants properly change the displayed font in GTK, only first option works properly with Java Swing (If it's using GTK look and feel).
It seems to only fork if there's a font with exact family name in fc-list

Here are the lines where this issue originates from:

https://github.com/nwg-piotr/nwg-look/blob/main/uicomponents.go#L245
https://github.com/nwg-piotr/nwg-look/blob/main/uicomponents.go#L247

Attached screenshot with the demonstration of the issue:
Top screenshot: Swing properly changes font, but nwg-look's font selector displays it as "None"
Bottom screenshot: Swing fallsback to using another font, but the font in nwg-look is properly shown

If the fonts were set by family name (which is shown in fc-list) instead of display name, that would also fix fonts in java applications.

All theme settings are correctly applied, but after restarting Sway config all reset to default Adwaita theme. The only workaround for this is using import-gsettings script https://github.com/swaywm/sway/wiki/GTK-3-settings-on-Wayland

Hello, I tried this out on arch linux, sway 1.7 with a couple gnome apps.

I used Adapta before and used nwg-look to try and switch to Adwaita and/or Adwaita-dark:

At first it seemed to work: easyeffects and the keyring unlock dialogue both now use the theme as shown by nwg-look's preview.
But then I noticed that galculator and evince use a light theme version instead:

Am I doing something wrong?

hi when i set a size for the cursor it dosen't apply it.(it only applys it for google chrome)
i did get it working by setting the cursor in .Xresources
but i wanted to inform you with this problem

i'm using dwm on debian 12

I already have go 1.20, gtk+3-devel, xcur2png, glib-devel, and cairo installed all through xbps which I'm pretty sure covers everything. This might be a void specific thing, or I messed something up

The new settings and welcome even for those who are not using nwg-shell. It would be great to be able to install it as a standalone application. instead of lxappearence.

When i run nwg-look -a it's not change gtk2 theme

If you set a custom cursor theme without that folder, index.theme will never be created and the settings are not properly applied. For any updated setting file nwg-look should create the folder if it does not exist.

~/.icons/default/index.theme

Workaround:

mkdir -p ~/.icons/default

Hello is there or in plan to have possibility to change setting directly from command line?

Could be useful to quickly change let's say GTK theme between light and dark theme via keybinding.

Something like:
nwg-look -c gtk-theme="theme-name"

Thank you!

At least I think so and where vast majority user configs are, not in $XDG_DATA_HOME (~/.local/share)

Summary: https://wiki.archlinux.org/title/XDG_Base_Directory#User_directories

OS: Arch Linux
WM: wlroots-based
nwg-look: 0.1.1

First off, thanks for this great tool, it very much improves the user experience of theming!

Not sure whether this is a bug, but when picking a cursor theme I still have to set the theme manually in ~/.icons/default/index.theme to make it visible on the plain WM layer/background (on waybar and GUI apps it's working as expected), leaving it blank will make the theme fall back to the "system" cursor.

Any ideas are appreciated,
Thanks again
