Application drawer for wlroots-based Wayland compositors

Hi, I’m Piotr - a middle-aged clerk and after-hours FOSS developer. I’m interested in Linux, Wayland & GTK.

• I use sway and Hyprland on Arch Linux;
• I have been working on the GTK shell for sway and Hyprland called nwg-shell;
• I prefer python to shell scripting and golang to C.

How to reach me:

• Join the nwg-shell Discussions, or
• submit an issue on GitHub on the appropriate project page, or
• find me in the nwg-shell Matrix space, or
• drop me a line by email.

Do not invite me to a live chat, unless you have diction like sir John Vincent Hurt. I'm quite useless at listening to English.

If you'd like to buy me a coffee, you may use GitHub Sponsors (link in the left column) or Liberapay:

nwg-drawer's Issues

Newest update doesnt respect NoDisplay=true

For some reason the applications I have hidden by copying the .desktop files to ~/.local/share/applications and appending NoDisplay=true are not hidden anymore in the newest update.

[performance] speeding up initialization.

as a result of the conversation in #19 I did an investigation into where time was spent during initialization.

turns out around ~80% of the time is spent on these lines.

I implemented a POC to speed up the total initialization time by around 4x. reducing the time from 520ms -> 100ish ms.

unfortunately it introduced a seg fault issue that seems related to the gtk bindings being used. (I'm assuming its due to the finalizer bugs that the binding library has in its issue tracker)

but wanted to bring this work to your attention just in case its useful.

Dead icons in nwg-drawer

Hello,

I'm finally coming back around to try and finish configuring and styling my launcher after a bit. I've been reading through the documentation on the entire set of nwg-launchers, as well as just nwg-drawer and -grid and am failing to see anything about how to at least identify the broken apps. Unlike most apps (even if the icon isn't right) where I can hover over the icon and at the bottom of the screen it will tell me what it is, these simply do nothing and say nothing, and I'd really like to get rid of them. I guess they were things pinned to favorites in the past. I'll include a screenshot below so you can see what I am talking about. Aside from going through the entire list of packages and seeing what matches up and what doesn't for .desktop entries vs. pacman -Q output, is there another more efficient way to figure this out specific to this package? Honestly even just resetting the entire thing and starting over would be fine too, but I am also having issues getting pacman to uninstall the packages as well, as it does not list those particular ones. It's been like a year since I started using it and I use your panel and bar too, so I think what I ended up doing was installing the entire launchers or shell package, because I also have nwg-grid and nwg-dmenu installed, along with Azote, nwg-look, and some other packages. Honestly I cannot claim to remember for sure. Any ideas to help me figure this out would be much appreciated, especially regarding where the best place to modify both the style specifically the drawer and if there is a config file that I cannot find that will let me toggle favorites, etc. I know I enabled favorites at some point, but I think I only had the packages individually installed at that point, so I'm afraid I do not remember where I did that. And no, simply right-clicking those does not make them unpin, I manually unpinned all of the favorites just to see if that would clear the field as well. This has been going on for a long time so it doesn't appear to be caused by any other app updates, etc., but I am finally trying to get around to fine tuning the launcher.

It's Monday morning and my coffee hasn't hit the back of my brain yet, so if I left something out sorry, please let me know. I probably did or am confused about how it's packaged. All help is appreciated.

Machine:
Surface 6 Pro
Arch Linux / Swayfx (all packages updated to latest a few minutes ago via pacman and yay)
Swayfx should be a fully up-to-date fork of normal Sway, swaymsg -v shows:
swaymsg version 0.3.2-19414f6 (Jul 11 2023, branch 'master')

Here is a screenshot of what the broken icons look like when the launcher is pulled up:

Here are the apps that pacman shows under nwg:

Neofetch in case it has more helpful information:

Please let me know if you need any sort of dump or whatever, and how to pull it for you if you don't mind.

Thank you for your help!

run in terminal does not work if nwg-drawer started from a key binding

The defaultStringIfBlank function added in #20 expects the os.Getenv("TERM") to be blank in order to return the fallback value. However, if we start the drawer from a key binding, the returned value is "linux", so this won't work.

I hide the apps without icons and It does not detect `~/.local/share/applications/*.desktop` files

Hello,

I want to hide these apps without icon:

And it does not detect the desktop configuration files from ~/.local/share/applications where VSCode desktop files are located and are not found in the nwg-drawer.

Launching thunar from nwg-drawer opens in sway config directory

Issue is fairly straight forward but im not finding anything I could be doing to cause this. I checked my desktop entry for thunar and nothing is out of the ordinary. If I launch from my hotkey it opens in homedir by default, which is expected behavior. Not sure how I can change this problem.

Keep up the great work, loving everything still!

Drawer becomes unresponsive for some inputs

I'm using nwg-drawer 0.2.8 on NxOS 22.05.

How to reproduce

1. Use NixOS?
2. Install Tor Browser.
3. Launch nwg-drawer, start typing tor-

In my setup, the program just freezes and freezes my entire Sway desktop. If I hit Escape, the nwg-drawer exits and my desktop is back to normal after some time (around 10 s).

I don't know why Tor Browser in particular triggers this behavior. I have also noticed that nwg-drawer is not very responsive in general. Response to keypresses takes always takes at least half a second.

nwg-drawer output:

Feature Request: Support for OnlyShowIn and NotShowIn

It would be cool if nwg-drawer would support the OnlyShowIn and NotShowIn from the XDG Desktop Entry specification. This would remove some unnecessary applications from the users view, making the application overall a bit more cleaner.

-nofs command doesn't disable filesearch

In my terminal i ran nwg-drawer -nofs
I then proceeded to type in firefox, which has alot of files in cache.
When i type the r in firefox nwg-drawer slows to a hault trying to get all the files to list, even though I gave the -nofs argument

Searching by typing misses keypresses after 0810250b3ad27a850033fd57d1519008f0828cd7

As per title, this commit seems to introduce some regression on the search-by-typing functionality.

Sometimes keypresses are not registered at all, some other times, after typing one letter, the focus is grabbed by the first available entry.
This causes the second letter to be lost. A third letter is again appended to the input. Rinse and repeat.

I specified the first entry 'cause if there is no entry, the input field doesn't lose focus.

Add Filter / Source Selection

Is it possible to add filters to nwg-drawer?

Example: I would like to create a key bind to open a menu that only displays Games application.

In nwggrid I do this by a different feature. There I can select the source folder for the .desktop files. To be honest this is not always exactly what I am looking for since I have to manually maintain all the desktop files. But it is also a good feature to have, for example using it I can not display some useless shortcut that is automatically create under /usr/share/applications.

How to add icons to categories?

I love this new launcher, a huge improvement to nwggrid! I love the fact that it works with my GTK theme, so I don't need to use hacks to make it work in light mode :)

I see in your screenshots that you have icons for the categories, how do I add those? I'm guessing they should be provided by the GTK theme?

Panic when run `pkill -USR1 nwg-drawer`

Description

Actual result

• Run the command nwg-drawer -fm nautilus -nocats -nofs -o 1 -ovl -r in a first terminal
• In another terminal run pkill -USR1 nwg-drawer
• See nwg-drawer panic.

Categories not showing

First thank you for making so many great tools. I am using SwayWM on Arch and nwg-drawer is exactly what I am looking for.

I have installed nwg-drawer on two of my machines, both have same set up (Arch+Sway). However, on my laptop (thinkpad), nwg-drawer does not have any categories, other than "All". On the other machine (thinkcentre), all categories (including icons) showed up correctly.

I checked /usr/share/nwg-drawer and I do have all the necessary files in the desktop-directories directory. On both machines, I use default settings without any modification.

I also noticed that on thinkcentre, nwg-drawer automatically copies drawer.css to my local config folder, even after I try to delete it. This was not the case on my thinkpad.

All packages are latest., installed from official repo.

The only difference I can think of is that Thinkcentre used to have Gnome installed, and then I uninstalled it to switch to Sway. On Thinkpad, I started fresh with Sway. I wonder if there is any on Gnome that made nwg-drawer categories working properly?

Thank you!

Add an option to select the first application by default when pressing ENTER or the direction arrows after a search

Description

Add an option to select the first application by default when pressing ENTER or the direction arrows after a search. Currently this scenario occurs only when launching nwg-drawer and without having done a search.

Actual result

Without search

• Launch nwg-drawer
• Press ENTER
• It launches the first application in the list

And

• Launch nwg-drawer
• Press an arrow key
• It moves the selection in the direction chosen from the first application in the list

With search

• Launch nwg-drawer
• Enter the beginning of the name of an application.
• Press ENTER
• This has no effect

And

• Launch nwg-drawer
• Enter the beginning of the name of an application.
• Press an arrow key
• It moves the selection in the direction chosen from the searchbar

Expected result

Without search

Keep the current scenario.

With search

• Launch nwg-drawer
• Enter the beginning of the name of an application.
• Press ENTER
• Run the first application in the list

And

• Launch nwg-drawer
• Enter the beginning of the name of an application.
• Press an arrow key
• Move the selection in the direction chosen from the first application in the list

Dotted lines not in drawer.css

Hi Piotr, sorry if this is kind of a silly issue but I'm trying to figure out how to change these dotted lines to solid lines:

The default drawer.css (https://github.com/nwg-piotr/nwg-drawer/blob/main/drawer.css) has dotted line values for pinned-box and files-box, but it seems these two lines in the screenshot are something else not in the file.

I poked around a bit to try and find any other version of the drawer.css which describe more of the options that are being set, but I'll be honest I'm not really sure what I'm looking for. If they can't be changed it's no big deal, I just thought I'd ask before giving up. 😄

Thanks for taking a look,
-Jeremy

Add CI

it would be nice to have linting and testing enabled

[CHANGED BEHAVIOR] New installation opens default list differently, can't fix

This is less a glitch or bug I believe but my hard drive recently failed and I was without nwg for around a month. Instead of copying a snapshot over I decided to just throw together a whole fresh install. I'm still back with nwg of course lol. But now when I open the drawer, it selects the first icon in the alphabetical list is selected, where previously it selected the first application in my favorited list at the top. Is there a setting I am missing somewhere? I have been looking for any positional options but I haven't seen any yet.

New option --config

Could you add the --config option to point to a different folder/file?

I like to keep everything in one folder like sway or hyprland.

Then we can have different wayland desktops next to each other.

Close nwg-drawer if the command `pkill -USR1 nwg-drawer` is called and nwg-drawer is open

Description

Add a pattern to close nwg-drawer if the command pkill -USR1 nwg-drawer is called and nwg-drawer is open.

Actual result

In background:

• Launch nwg-drawer -r

In foreground

• Press the shortcut for run pkill -USR1 nwg-drawer
• nwg-drawer is displayed
• Press the shortcut for run pkill -USR1 nwg-drawer
• This has no effect

Expected result

In background:

• Launch nwg-drawer -r

In foreground

• Press the shortcut for run pkill -USR1 nwg-drawer
• open nwg-drawer
• Press the shortcut for run pkill -USR1 nwg-drawer
• close nwg-drawer

[REQUEST] add window margin

I would like to configure nwg-drawer to look like it's coming out of the top of my screen. However, I see no way to change the margin of the window. Just as an example of implementation, swaync solved this by adding "control-center-margin-bottom" and others to an additional config.json.

Also, If this is not a feature of interest, how would I allow nwg-drawer to cover my bar (waybar)?

Touch swiping results in a mouse click at the end of the action

Describe the bug

When swiping up/down on a touchscreen enabled device the drawer does scroll down while the scrolling action is in progress but immediately exits upon lifting the finger from the touchscreen.
Essentially, at the point where the pointer is at the end of the touch action a mouse click is done, which either opens the app the pointer is on or quits the drawer.

To Repoduce

Steps to reproduce the behavior:

• Install package from AUR
• Run nwg-drawer

Expected behavior

A swiping action should not result in a mouse click.
I realize this might be difficult to reproduce without a touch device so i'd happily help to debug this if you are interested in making this work on a touchscreen.

Incidentally, the nwggrid works as expected

Desktop (please complete the following information):

• Device: Acer Switch Alpha 12 (2in1)
• Arch Linux

feature: prefer most used applications

I most likely start the same application. e.g when I want to run nautilus I search for files. As I also have FileZilla installed it's sorted before nautilus.
I wonder if it makes sense to count how often an application was launched and prefer sorting the applications this way. So you don't need to do additional navigation in case there are multiple matches.

Blank Icon on Pinned bar, Can't be Removed What-so-ever

There is a blank app on my pinned bar. I do not see this app in my "All applications". This happend when I installed Terraria twice by accident the other day. I pinned both of the Tarraria's .desktop icons to the pinned bar, then I noticed that there was two. So I uninstalled 1 of the apps, and their .desktop file, but for some reason, the pinned icon was still there, I tried right clicking it to unpin, it doesn't work. I tried reinstalling nwg-drawer, doesn't work. I also tried completly removing the /usr/share/application folder, all my icons were gone except the pinned blank icon.

Also installed nwg-menu, the blank icon is there.

Here are my Specs

nwg-drawer send string to search from command line

anyway to send a string to search from command line? would be good having a way to nwg-drawer -string-search SomeApp, then the app starts with string filled in the search already

/tmp/nwg-drawer.lock was owned by other user

Wish everyone a Merry Christmas :-)

Spaces in command are not being processed correctly.

Commands with spaces (in file names for example) won't run no matter what.

Suppose I want to run the following command

retroarch Chrono Trigger.smc

In which "Chrono Trigger.smc" is the name of the file. In standard bash we can express the middle space by two different ways (that I know of):

• Backslashs: retroarch Chrono\ Trigger.smc
• Double Quotes: retroarch "Chrono Trigger.smc"

Ideally they would both work in nwg-drawer but it seems that none of these does.

I tried to go through the source code but couldn't find a clear path to fix it.

Entry description is updated only on mouse hover

I noticed that the desktop file description shown at the bottom only seems to update when the mouse hovers on an entry.
It doesn't follow the selection when navigating with keys nor when filtering with the search bar.

nwg-drawer does not start when running a second wayfire session under same user

While running some tests I started a second wayfire session under my regular id from a linux console/tty.

In that second session I try to launch the drawer via the usual key combo and nothing happens.

So I fire up a terminal and I see this message:

INFO[0000] Showing resident instance (PID 2200)

Now I have made nwg-drawer resident so that there is no delay when I invoke it in the course of my wayfire session and It looks like a side-effect of this approach is that I can no longer invoke in it in a second wayfire session.

Is this to be expected... or is it a case of my not doing it right?

Among my wayfire session 'autostart commands' I have:

nwg-drawer -r

As to my wayfire bindings I have:

<Ctrl> <Alt> KEY_Y nwg-drawer

Not really relevant but the reason I'm doing this is that I'm trying to hunt down the applications that are not 'native-wayland-enabled' and have disabled XWayland before launching the second session (and I'm too lazy to clone my setup to another id :)

Some icons appear smaller and are offset when searching

Some apps cause the search results to have smaller icons that are offset. The ones I identified for now are Code - OSS and simplenote.

normal result:

Styling issue.

Hi! Nice project. My first install on FreeBSD 13, Sway, default css file. What`s wrong?

Change term overriding variable and improve error handling?

I was troubled by an stupid issue where I can launch other desktop entries but not the Looking Glass Client. Today I decided to investigate it.

Initially I though the desktop entry was bad but it worked with gkk-launch. I then launch nwg-drawer in terminal and found that it is trying to run xterm-kitty to launch a console program (which looking-glass-client is). I then realized that nwg-drawer uses $TERM as the default terminal, which is almost never going to give you a executable file name, since this variable denotes the terminal capabilities, not the binary itself.

Unfortunately there is no standard way to indicate the preferred default terminal, but whatever that would be, it is not gonna be $TERM, and such silent failure is confusing, as there is no error in main menu, and no graphical error message when the terminal failed to launch.

I think we could use $TERMINAL as overriding variable instead (used by i3 and suggested in another post, and actually check if this is a valid terminal and tell the user. Or show a graphical error message when the terminal failed to launch.

Uninstalled apps impossible to unpin

High CPU utilization

Currently nwg-drawer uses a lot of cpu cycles for polling the USR1 signal and file change trigger variables at a high interval: https://github.com/nwg-piotr/nwg-drawer/blob/main/main.go#L494-L529. This can be avoided by using channels and a goroutine to only execute tasks in the event loop if necessary. For example, by changing showWindowTrigger into a channel and replacing the linked function with the following goroutine, the cpu utilization drops to 0 while not affecting the responsiveness.

go func() {
    for { 
      	< -showWindowChannel;
        glib.TimeoutAdd(uint(0), func() bool {
            // Insert code to show window
            return false;
        });
    }
}()

nwg-drawer upgrade from 0.2.8 to 0.3.0 broke

The numbers mentioned in the panic aren't in my drawer.css file. I can also try using nwg-drawer with an empty css file and no arguments but I get the same error. I believe whatever change from 0.2.8 to 0.3.0 broke nwg-drawer. A fix would be appreciated as I don't have an easy way to open applications now.

Do not include binaries in the repo

Unless they are needed for some reason, build files should not be checked in the git repo so the .gitignore file should include a directive to ignore the bin folder.

After that, the already tracked bin directory shoud be removed from the repo, by using git rm.

I already added the changes in nightly-brew@7f18eee, if you would like to take a look.

Drawer not following CSS with newest update

Morning Piotr,

Unironically loving the updates we've been getting on this, but on the latest drawer update. I believe I still have default colors for it, black but slightly transparent. Its a sleek look ngl. But now it appears blue-ish and slightly transparent. I have confirmed it is selected to use preset-0, and the following is the code for that file and a screenshot of what it looks like now.

  window {
      background-color: rgba (20, 20, 20, 0.95);
      color: #eeeeee
  }
  
  /* search entry */
  entry {
      background-color: rgba (0, 0, 0, 0.2)
  }
  
  button, image {
      background: none;
      border: none
  }
  
  button:hover {
      background-color: rgba (255, 255, 255, 0.1)
  }
  
  /* in case you wanted to give category buttons a different look */
  #category-button {
      margin: 0 10px 0 10px
  }
  
  #pinned-box {
      padding-bottom: 5px;
      border-bottom: 1px dotted gray
  }
  
  #files-box {
      padding: 5px;
      border: 1px dotted gray;
      border-radius: 15px
  }

Not sure if this is caused by something I did but it shouldn't be as I haven't been making any changes in this area at all lately. Thanks for providing this great suite!

Launched applications are not detached from the launcher process when resident

As per the title, applications are not detached from the launcher process when the drawer instance is resident.

Normally this goes unnoticed, but if SIGKILL is sent to the launcher, all child processes are terminated as well.
Probably related, in the screenshot it's also possible to notice gimp as a zombie process; this happened after quitting gimp.

It would be better instead if processes were left to the init system to handle, similarly as it happens when a standalone instance of the drawer executes an app, then quits.

Launching certain apps

When lauching certain apps the the app doesnt launch for excample if I launch gnome-chess it will not launch if loading from sway config use either alt+f1 or the icon on the panel. If I kill all nwg-drawer applications and launch nwg-drawer from terminal it works as expected.

Setting -nofs causes nwg-drawer to crash when clicking category buttons

On Arch Linux, nwg-drawer version 0.1.7 installed through the AUR. Using Sway WM.

When bound to the $menu variable in Sway's config with set $menu nwg-drawer -ovl -nofs, launching via a Sway keybind and left-clicking any category button causes nwg-drawer to crash immediately. Removing the -nofs argument allowed categories to work without issue, leading me to think the issue is related to this argument.

Catergory Buttons Styling Does Not Work

The styling for category buttons does not work. The buttons continue to take the styling from the buttons.
nwg-drawer version 0.1.3

DRAWER.CSS

window {
    background-color: rgba (36, 47, 79, 0.95);
    color: #eeeeee
}

entry {
   box-shadow: 0 0 6 5 #2e3440;
   background-color: #3b4252;
   border: none;
   border-radius:10px;
}

button {
    box-shadow: 0 0 6 5 #2e3440;
    background-color: #3b4252;
    border: none;
    border-radius:5px;
    margin: 4px;
}

category-button {
    background-color: transparent;
    padding: 1px;
}    
    

button:hover {
    background-color: rgba(129,161,193,0.7);
}

button:focus {
    background-color: #5e81ac;
}

#pinned-box {
    padding-bottom: 10px;
    border-bottom: 1px dotted gray
}

#files-box {
    padding: 10px;
    border: 1px dotted gray;
}    

Zombie children

When using the nwg-drawer in resident mode (starting the application with the -r flag), the drawer should collect the exit status codes of all children, which is not the case and leads to a lot of zombies in the process tree. An easy fix would be to just insert a cmd.Wait() after https://github.com/nwg-piotr/nwg-drawer/blob/main/tools.go#L586, like shown in the snipped below. But that is certainly not the optimal way to solve this problem.

cmd.Start()
go func() {
    cmd.Wait()
}()

Allow specifying settings in a config file

Hi, would it be possible to specify launch settings in a config file as well?
I think it would be of help in standardizing systemd user units and xdg autostart desktop files.

Ideally, nwg-drawer could try to read something like "$XDG_CONFIG_DIR/nwg-drawer/settings" at startup.
For those use-cases where "-r" is specified, the launched instance could first try to trigger the background one, if it exists (kind of like it already does).
If no background instance is running instead, it just starts as that.

Of course, cli arguments should still have precedence over the config file, to allow overriding the default behaviour when needed.

Cannot run on Raspberry Pi (arm64)

Hello. Running nwg-drawer on Ubuntu Arm 64 (on Raspberry Pi) gives an error:

cannot execute binary file: Exec format error

Is nwg-drawer x86-only?
