21:44:54 <haskellbridge> <iqubic (she/her)> I'm looking to set up some Named Scratchpads. I'm not sure what "Query Bool" as the query parameter of the NS constructor? How do I know if I want to use "className" or "appName" and how do I get those values?
21:47:13 <haskellbridge> <iqubic (she/her)> I'm wanting to make an Emacs window into a scratchpad. According to what I've read online using "emacsclient -c --frame-parameters='(quote (name . "scratchmacs"))'" as the way to launch Emacs sets either the "className" or the "appName" and I'm not sure which.
21:49:43 <geekosaur> a Query Bool is what goes on the left side of `-->` in a ManageHook
21:49:46 <haskellbridge> <iqubic (she/her)> Using "xprop" gives this piece of info: "WM_CLASS(STRING) = "scratchmacs", "Emacs"". I think that means I want to use something like "appName =? scratchmacs" right?
21:50:02 <geekosaur> (NamedScratchpads in effect build custom ManageHooks)
21:50:19 <geekosaur> with quotes around "scratchmacs", yes
21:50:32 <haskellbridge> <iqubic (she/her)> Right. Because that has to be a string.
21:51:09 <geekosaur> https://github.com/geekosaur/xmonad.hs/blob/hilfy-2023/xmonad.hs#L94-L132
21:51:39 <geekosaur> (and `remoteCrawl` is just above it)
21:51:58 <haskellbridge> <iqubic (she/her)> So, appName is the first string returned by WM_CLASS? Got it.
21:52:09 <geekosaur> yes, and className is the second
21:52:56 <haskellbridge> <iqubic (she/her)> I don't see any way to change the class name of a new emacs window, but I don't have a way to change the appName
21:53:14 <geekosaur> there's a utility script in xmonad-contrib (that sadly doesn't get installed) that outputs properties in ManageHook format: https://github.com/xmonad/xmonad-contrib/blob/master/scripts/window-properties.sh
21:53:41 <geekosaur> in general you don't change className, it's supposed to apply to all instances
21:55:28 <haskellbridge> <iqubic (she/her)> Right. What's going on here is that I have Emacs running as a daemon in the background, and then I'm just firing up a client so that I can do some edits and things. And then I can close that window without losing all of the Emacs state.
21:56:31 <haskellbridge> <iqubic (she/her)> What does "(noTaskbar <> doFloatPlace)" mean
21:58:33 <geekosaur> doFloatPlace just composes a PlaceHook with doFloat (https://github.com/geekosaur/xmonad.hs/blob/hilfy-2023/xmonad.hs#L298-L299)
21:59:09 <geekosaur> noTaskBar is from XMonad.Util.NoTaskbar and hides windows from EWMH compliant taskbars
21:59:16 <haskellbridge> <iqubic (she/her)> Why are you doing that? What benefits does that give you?
21:59:19 <geekosaur> (I use xmonad as WM for Mate)
21:59:38 <haskellbridge> <iqubic (she/her)> I see. I didn't know you could use that.
21:59:42 <haskellbridge> <iqubic (she/her)> +do
22:00:07 <haskellbridge> <iqubic (she/her)> I'm running XMonad without any sort of DE
22:00:27 <geekosaur> because I open like 8 `sxiv` windows (still trying to reproduce https://github.com/xmonad/xmonad-contrib/issues/753) and I don't want them clogging my taskbar
22:02:28 <geekosaur> the XMonad.Desktop hierarchy provides support for xmonad as WM for a number of desktops. read the wiki because you generally need to reconfigure the DE to use xmonad; for example https://wiki.haskell.org/Xmonad/Using_xmonad_in_MATE
22:02:30 <haskellbridge> <iqubic (she/her)> Do you know if XMobar is EWMH compliant? I don't want named scratchpads to show up in the list of workspaces that XMobar reports.
22:02:39 <geekosaur> it's not
22:04:11 <haskellbridge> <iqubic (she/her)> Got it. So I'd probably have to modify my Pretty Printer to explicitly exclude those.
22:04:14 <geekosaur> to hide the NSP workspace from the information that xmobar gets, you want https://hackage.haskell.org/package/xmonad-contrib-0.18.0/docs/XMonad-Hooks-StatusBar-PP.html#v:filterOutWsPP
22:04:56 <haskellbridge> <iqubic (she/her)> Yeah. I can totally use that!
22:06:07 <haskellbridge> <iqubic (she/her)> What is "myPlaceHook" doing for you? (noTaskbar <> doFloatPlace)
22:06:07 <haskellbridge> <iqubic (she/her)> -(noTaskbar <> doFloatPlace)
22:06:13 <haskellbridge> <iqubic (she/her)> https://github.com/geekosaur/xmonad.hs/blob/hilfy-2023/xmonad.hs#L296C1-L296C42
22:07:29 <geekosaur> places floating windows near the center of the screen, not allowing them to go outside the screen unless they're straight-up too big to fit, and trying to keep them from overlapping each other
22:09:39 <haskellbridge> <iqubic (she/her)> If I want to do something simple, can't I just use "customFloating"?
22:10:02 <geekosaur> yes
22:10:50 <haskellbridge> <iqubic (she/her)> What do the 4 parameters to "W.RationalRect" even specify? The docs don't explain it. It just shows it as 4 strict Rationals with no explanation.
22:11:40 <geekosaur> it's an X112 Rectangle rephrased as a proportion of the screen, since it can be applied to screens with different sizes
22:12:40 <haskellbridge> <iqubic (she/her)> Ah. I see.
22:13:11 <geekosaur> https://github.com/geekosaur/xmonad.hs/blob/hilfy-2023/xmonad.hs#L112
22:14:26 <geekosaur> start a quarter of the way across the screen horizontally and right at the top vertically, width is half the screen, height is 35/100 of the screen
22:14:57 <haskellbridge> <iqubic (she/her)> Right. I see.
22:15:05 <haskellbridge> <iqubic (she/her)> "myPlaceHook = inBounds $ smart (0.5, 0.5)"
22:15:17 <haskellbridge> <iqubic (she/her)> What do the two 0.5s there mean?
22:15:34 <geekosaur> https://imgur.com/CtdtqU0.png
22:15:54 <geekosaur> indicates the center of the screen (halfway across in both X and Y dimensions)
22:16:49 <haskellbridge> <iqubic (she/her)> Right. Got it. I'll have a play with this and see what I can get setup.
22:16:53 <haskellbridge> <iqubic (she/her)> * set up.
22:17:33 <haskellbridge> <iqubic (she/her)> I assume your most recent image is wide because you have a dual-head setup. Is that right?
22:17:39 <geekosaur> yes
22:17:59 <haskellbridge> <iqubic (she/her)> Cool. Thanks for helping me understand this.
22:19:09 <haskellbridge> <iqubic (she/her)> I've been using XMonad for a while, but I've only just now decided to make major changes to my config.
22:19:56 <haskellbridge> <iqubic (she/her)> It's actually really easy to use XMonad with NixOS.
22:21:00 <haskellbridge> <iqubic (she/her)> I had a few ideas for making my own layouts, but then found out that all of them could be found in contrib already.
22:29:20 <haskellbridge> <iqubic (she/her)> As a woman in tech spaces, people sometimes don't want to help me. Thank you for helping me understand XMonad.
22:29:44 <haskellbridge> <iqubic (she/her)> And to make matters worse, I'm a trans woman!
