Does your Window Manager Swallow? 

I'm not like those other window managers, you know...

I click the file and VLC shows up without any issues What is this boomer talking about

"Babe! It's 4PM, time to edit your dotfiles!"

I see you have your Steve t-shirt on, Minecraft let's play when?

2:22 Weird boomer tries to attempt zoomer clap-cut

I am going to have you rename this video sir

He didn't say "based" in this video, if you're curious.

I am guessing the clap at 2:28 was to help with editing so you know where to cut. I wonder if you get a dog whistle and use that instead and have an FFMPEG script that auto cuts when it hears a certain frequency.

You have been very productive recently

0:51 Luke used his mouse, jesus christ what a normie

2:27 The slap and the quick key press with the face was hilarious! You made my day luke! Laughing my ass off, for real!

So what's the proper etiquette? Do I leave my window manager a tip on the dresser now or...

Ha I learned something new again! Thank you for always coming up with new stuff! I've used DWM since like a month before you started using it (I've been following you on RU-vid since a month after I started with i3) and the possibilities are amazing! I'm getting a "new" Lenovo flex 14 with touchscreen soon, which I'm putting a Manjaro KDE on just to see what that's like (Blender doesn't like DWM, it doesn't let me close the Preference window without crashing) but I'm gonna miss the simplicity, low overhead and the ability to customize it that DWM has. Although I'm contemplating hacking DWM into KDE as a substitute for Kwin just to have the best of both... I love Linux!

OK I was quite happy with bspwm and despite all your dwm praises I was not convinced to switch but now I am finally sold compiling dwm right now

This is similar to plan9's rio window manager, where an application can take over the terminal window, but the implementation is much simpler. Thank you for showing this, now I have no reason to ever use any other wm.

That's awesome! It reminds me of DOS games when you start it from the terminal and it covers the whole screen! It makes the terminal and the tiling paradigm much more user friendly and useful! Weird that it was not more widespread let's say 10 years ago...

Well I dont have this problem because my iq is so high I don't even have to use bloat like a terminal. I just manipulate individual bits using my bare hands

I like it but I think there should be a function to unswallow with a shortcut key. Just in case you happen to need to see the output live in a such a program that you probably will remove after one time use as you only need it for some rare occasion in which case you don't want to bother to change the config and compile dwm just for the single run of a program.

This is just sending the terminal automatically to the scratchpad. i3 or sway have a scratchpad. You could script this outside your wm config file or make use of a tabbed windows style. Bloated feature.

Luke Smith watching Mental Outlaw's RU-vid video. This is some epic chad elite crossover right here.

dwm is suckless, AND it swallows? I'm impressed.

Eh, seems kinda cool but I prefer the flexibility of using & I think. Also I forget I can always use ctrl+z + bg to send it to the background. Bonus is: if you use `setopt nohup` in your zshrc it won't kill those background processes if you kill the window. Otherwise you'd need to use `disown` every time Note: I already use dwm

2:26 I find that transition so hilarious for some reason.

My 269 IQ solution for this problem was "mpv greenFrog.mp4 && exit"

mux on the blit terminal by Rob Pike had this in 1982

another 'problem' in linux that was elegantly solved in plan9 some 30 years ago.

this comment helps with the algorithm

Thanks, now I'll use Rio from Plan9

You can just also push it to bg and then disassociate it with the main process or w/e...it’s usually the first solution you find if you’re looking to solve this problem. Swallowing is always better though! 😛

1:57 *SOY* he was thinking about i3 users that's why he typed that

When Luke messing with his beard, It means he says something he does not like it deeply or supporting it or does not care about existence of that shit. I can feel it.

This feature alone made me switch from i3 to DWM. Now I have patched my DWM to be exactly how I like it and I will probably never leave DWM

My window manager spits and get's mad I didn't warn it in advance.

Man, I’ve really wanted this patch. Thanks for sharing.

what's wrong with "& disown"

Hey Luke, nice video! I thought about how you said up your webcam on your dwm setup?

Pretty sure in a floating window manager you can just minimize your terminal, or launch a dedicated app like gwenview. Another solution would be to use utilities like dtach and dvtm, to respectively detach from the process and maintain use of your terminal. I'm not really sold on tiling window managers even though I used to use dwm, but I will say that certain suckless programs are excellent . BTW, if you *really* want to watch a video in your terminal, output it with libcaca.

For the record, if no one is paying attention, I'm learning git difftool (just set nvim to my difftool), and dwm is going to be the program that I learn it with - l'll need the difftool for other things as well, but the suckless suite will be great practice). For those not leaving i3, i3ipc has a swallow script (not as efficient as patching source code).

DWM swallows?! I'm sold! 💦

Dang this is perfect. I installed DWM in FreeBSD a bit ago and it’s been an annoyance to sent the terminal to another tag whenever I open my browser

When will Mocrosoft release this windows manager on my Windows 10?

good point. you can still switch to tabbed mode. but if you are a game dev, and want console log, you have to do this for every app you want that. still. No hate. I respect every DEs and WMs in linux, just like every Distro.

Confirmed, Luke and Mental Outlaw are associates

Who would win, a "suckless" dwm with bloated patches or github/salman-abedin/devour with 4 lines of pure posix shell?

i used to do something like evince x.pdf & disown (maybe add an && exit to it ) but seeing this vid ill probably alias some commands to something like alias evince="evince $1 & disown " to make a workaround but i see your point dwm seems more intuitive planning to switch on it soon. Btw this was a great video

Hmm, had my eye on this patch for a while.. It would be nice to be able to hotkey switch between the spawned window and the spawning terminal. Haven't looked into it yet though.. Thanks again for another informative video!

Noticed this a couple hours ago when I was using anki - pretty cool

I didn't know I need this. Time to do that in awesome. Edit: I made my WM swallow

The only thing holding me back from testing dwm is that it's for X only (instead of Wayland). That's why I use sway.

For i3... In sequence, Split v and layout stacking do kind of that, did you know?

Can someone tell me which shortcuts did he use there? 2:27 I'm confused.

Why cant just use '&' symbol at the end.

You can just add '&' after a command to run it independently of the terminal.

Does anyone know how to make it work in Flatpak? The patch works for me but I don't know why it doesn't work in flatpak applications.

You should show more in detail how to patch dwm. I mean, we all know how to install ONE patch automatically. But I’ve always wondered how you install the next patches: once you installed the first patch, all the code gets shifted and line numbers don’t correspond anymore to the ones the author of the patch originally thinked and inserted in the diff file. So once you run the patch command you get a bunch of errors and nothing else works, until you manually find the appropriate lines and modify them. At least that’s what I’ve always did but that literally sucks and takes ages

A blue shirt?!? Like steve's from Minecraft? Glad you're repping the merch too, unlike fake fans.

doesn't "&" at the end of any command work????

isn't this what happens in plan9 too?

>he needs to patch his window manager to get it to swallow virgin "needs to patch it to be functional" dwm vs. chad "script it however you want it" bspwm

I'm liking dwm but my one gripe is that tag numbers are unique for each monitor. This isn't much of a problem until I detach my thinkpad from its dock: then the tags with the same number get smooshed together. I'd prefer to keep them separate but I have no idea how to do that.

What a bloat. You can put "&" after your command to run it in background. And there is zero point in covering your shell with that new window

You could also suspend the process with Ctrl+z then "bg" to send job to background and "disown" to detach process from terminal.

instantly patched my dwm i was thinking about a feature like this recently and this is so cool

I usually have a local tmux session with a bunch of shells and will use the same one for opening up videos in mpv, or I'll launch a video in mpv from rofi/wofi. I also have super-p bound to open my clipboard contents in mpv which works well if I've just copied the url of a RU-vid video or something. This is still cool, though. It reminds me of launching stuff on Plan 9.

the other way to run another app without tying up your terminal is to issue your command, but put & afterwards. example: mupdf document.pdf & and now the pdf will open and you can close the terminal or so something else in it. the terminal won't get swallowed though.

Is there a benefit to this versus a monocle window mode?

Hi, Luke! Very funny clap, little delay with screwed face and then cut. Lol.

I just use lf, and open multiple things to spawn into another video, I use the nohup command. But yeah this is badass, I'll incorporate it in thanks.

In i3: Run program Press meta+w

“Oh it’s one of those cute little retarded Pepe things”

It seems cool, but I wouldn't really patch my build of dwm. I like to see the output of my programs.

In i3, just put your windows in stacked mode () and add the & at the end. That way you have the flexibility to run things how you want. With Luke's method in dwm, when I open OBS and want to look at the logs (i.e. the default that this boomer is complaining about), it happens automatically. Switching your wm because you don't know keybindings or you don't know why defaults are the way they are is just dumb. Seriously, adding each program individually to a config file to make it just do the i3 default is dumb. Bad video is bad

If there will be v-split and h-split like in i3, I will move to DWM. For now it's inconvenient for me to switch to master-slave behavior, I just like to manually arrange my windows the way I want.

Window managers are bloat. Let me do all that in the TTY, without X, with the option of using a terminal multiplexer, and then I will be happy.

Doesn't seem to work in Ranger. If I open some video file from the terminal using mpv for example, dwm does swallow it, but it doesn't when I do the same thing in Ranger

Vim Diesel is at it again.

I wondered how it worked so I had a quick look at the source code. When a window gets swallowed, it actually gets both Withdrawn (which is one of the states a window can have in X besides Normal and Iconic) and then explicitely Unmaps the window (removes it from the screen), which is weird because the Window manager should already be doing that to withdrawn windows in the first place. Then the new window gets resized and moved to where the old window was.I use a stacking WM (openbox), so terminal windows staying open don't really bother me that much, since the window I opened is in front of them and I can always Iconify (minimize) the terminal, but I wondered if that could be done automatically. You'd pretty much do the same thing this patch does to detect whether a window is opened from the terminal and then set the WM_STATE property to Iconic. Then when the new Window is closed the property is reset to Normal. This would also give the user the option to bring up the terminal manually (which wouldn't be the case for a withdrawn window).The Wm should do all the heavy lifting af actually mapping and unmapping windows (which I don't kow if that is the case for dwm and other tiling WMs since they don't know what to do with iconified windows,

I think this should be just turned on/off on the fly instead of giving flags like "noswallow". Like win+S should toggle swallowing on/off and thus you can tell your window manager to swallow or not. Maybe will create a patch for this as sounds simple to do.

for_window [class="mpv"] floating enable solved the same problem for me

Cool patch, but why doesn't just running ink the background achieve this? IIRC that lets you quit from and resume using the terminal

What if you want to read program output for debugging? Can you override?

Nice feature

Thank you uncle Luke, very cool

I just add an '&' at the end of my commands for same behavior. What's the problem with that ?!

no one has ever been as sold as i am right now

Interesting, but as others have pointed out you can & or ctrl-z (zombie) and bg programs.

This precisely the problem I had with running software from cli.

super + w luke. like wtf this isn’t even an issue

Have you heard about the recent Brave fiasco? They autocomplete/replace (not sure which) certain URLs with their own affiliate links. What's your take on this?

mpv --fs Non-issue 🤔

So it doesn't suck. But it does swallow. 🤔

is there an option to not have it swallow the terminal, or bring it back up, when I need the stdout fromt the program I'm running? I mean without editing the config and recompiling just to run something I might only run once or twice.

Where did you get that wallpaper?? I like it :D

Wouldn't exec partially do the trick, expect closing the program and going back to the terminal?

I mean you could always just run it as a background job by appending an an & to your command

What if you want to suppress the swallow behavior just one time?

I always redirect to /dev/null and run in background. 2:27 LOL

Alright, this is why I'll try dwm.

Ratpoison has been able to do this since 20 years ago.

But i3 can do that... There's and ipc script called swallow, and you just use For_window ["instance" ="fuzz"] exec no-startup-id swallow Most window managers can swallow with an extension or patch. Even Windows 10 and MacOS can do that shit. Heck, you can just use the monocle layout in just one axis and achieve basically the same in dwm.
