Compile-time verification of keymaps
by Gwern Branwen 28 Mar '10

28 Mar '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 So today I edited into my xmonad.hs a binding to the Isohunt.com XMonad.Actions.Search engine for convenience. I naturally chose xK_i for the bound key. When I reloaded, I was surprised to see that mod-i failed to do as it was supposed to. Trying it again, it brought up irssi. That was when I realized mod-i had already been bound in my xmonad.hs, to runOrRaise for irssi, and that the irssi binding happened to be later in the list and so it quietly overwrote the Isohunt binding. After picking a new & unused key, I began reflecting on this. Certainly, this is expected behavior if you're familiar with Data.Map. fromList will do that - a list may have multiple values for a single key (such as xK_i) and the last value wins. But I think in an xmonad.hs, the context is somewhat different. There the semantics are somewhat different. We use 'M.fromList [stuff, more stuff, and the rest]' syntax because Haskell supports list syntax, and it makes life easier on the user to use such a common method. But do we *really* mean to say that it is a sensible thing to bind the same key to multiple contradictory definitions? It just so happens that [xK_i isohunt, xK_i irssi] is equivalent to a destructive update style of 'i = isohunt; i = irssi' when fed through the Map functions. So I thought to myself that maybe there was some static way of specifying a list without duplicates we could use in xmonad.hs. It would be nice to know that one cannot run xmonad.hs with inconsistent sets of bindings*. This checking would, even better, be done at compile-time so one could verify this by simply loading in GHCi (good for everyone who routinely reloads in Emacs or Vim). How to do this? Someone in #haskell suggested extensible records, but that sounds quite difficult. Another approach would be to scrap the static requirement, and simply provide the user a redefined 'fromList' which runs something like 'let x = map fst list in nub x == x' and does something if there are duplicates (calls error, spawns xmessage, etc.) I decided to try a variant of the latter at compile-time, using Template Haskell. I got fairly far with the help of mmorrow, but I didn't actually succeed. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEAREKAAYFAkkgYvgACgkQvpDo5Pfl1oLE3gCgkuHMlUO1+YT4oEFLzhHqmeuB QA4An3X72j1z+StumSOmnTXlTJhHeTft =fBDz -----END PGP SIGNATURE----- The idea is that one should be able to do something like this in xmonad.hs > '{-# LANGUAGE TemplateHaskell #-} > import XMonad.Utils.VerifyKeys > .... > myKeys conf@(XConfig {modMask = m}) = M.fromList $(uniqueTupleListQ [ -- rebind standard actions > ((m .|. shiftMask,xK_p), shellPrompt greenXPConfig) > , ((m, xK_d), raiseBrowser) ] ) VerifyKeys looks something like this: > {-# LANGUAGE TemplateHaskell #-} > module XMonad.Utils.VerifyKeys where > > import Data.List(nub) > import qualified Data.Map > import Language.Haskell.TH.Lib > import Language.Haskell.TH.Syntax > > uniqueTupleListQ :: (Eq a, Lift a, Lift b) => [(a, b)] -> ExpQ > uniqueTupleListQ xs = let ys = map fst xs > ns = nub ys > in case ys == ns of > False -> fail "uniqueTupleListQ: List has conflicting entries." > True -> lift xs The idea is that since we know the keymap at compile-time, we pass it, before it gets turned into a Map (and the relevant information lost), we analyze the list. 'fail' aborts the compilation if the list is bad. You can easily test this out in a different module with some simple expressions: > keymap1, keymap2 :: [(Char, String)] > keymap1 = $(uniqueTupleListQ [('a', "foo"), ('b', "bar")] ) > keymap2 = $(uniqueTupleListQ [('a', "foo"), ('b', "bar"), ('c', "bar"), ('a', "quux")] ) Compiling, this gives us something like this: > [1 of 2] Compiling Tmp ( Tmp.hs, Tmp.o ) > [2 of 2] Compiling Main ( xmonad.hs, xmonad.o ) > Loading package base ... linking ... done. > Loading package array-0.1.0.0 ... linking ... done. > Loading package packedstring-0.1.0.0 ... linking ... done. > Loading package containers-0.1.0.1 ... linking ... done. > Loading package pretty-1.0.0.0 ... linking ... done. > Loading package template-haskell ... linking ... done. > > xmonad.hs:113:12: uniqueTupleListQ: List has conflicting entries. Line 133 is keymap2. If we remove '('a', "quux")', which conflicts with the very first entry, we get: > [1 of 2] Compiling Tmp ( Tmp.hs, Tmp.o ) > [2 of 2] Compiling Main ( xmonad.hs, xmonad.o ) > Loading package base ... linking ... done. > Loading package array-0.1.0.0 ... linking ... done. > Loading package packedstring-0.1.0.0 ... linking ... done. > Loading package containers-0.1.0.1 ... linking ... done. > Loading package pretty-1.0.0.0 ... linking ... done. > Loading package template-haskell ... linking ... done. > Linking foo ... Now, this seems to be exactly what we want, doesn't it? But ultimately I had to admit failure. Template Haskell has a number of restrictions and omissions that make it unfeasible to use. For starters: If we apply uniqueTupleList to an actual keymap (like mine), we discover that uniqueTupleList's constraints are unworkable. Per the type sig, we need 'Lift b', the second half of each tuple in the key list. But XMonad requires b to be a X (), and X () is not instantiated for Lift**. Were it, we would still need Lift instances for Word64 and also CUInt. Lift instances probably wouldn't be too hard to write. The real killer, from an xmonad.hs perspective, is the module restrictions. Fundamentally, one *cannot* use inside a $() anything defined in the same file. {modMask = m}? Nope. greenXPConfig? Nope. 'term = XMonad.terminal conf'? Nope. And so on. It is a minimal set of bindings indeed which only makes use of literals and imported functions. So until Template Haskell improves, that avenue seems to be out. I'm not sure where to go from here. Had Template Haskell worked out, the path would've been easy, a matter of having users make a relatively small modification to their xmonad.hs, and perhaps avoiding entirely TH syntax. Does anyone have a better approach, or is this a foolish thing to want static safety in? ksf suggested that Yi has a combinator approach to keybindings which could solve it, but I am unsure how that works or could be adapted for XMonad.*** * Obviously the consistency is only valuable _in_ a specific Map; if we insisted that all Maps be consistent, then we couldn't override the default Map with our own. ** I may be misinterpreting the type error; possibly we actually need Lift for (X()) *** I'm cc'ing yi-devel since I suspect the topic may be of interest. -- gwern

Call for xmonad.hs
by Gwern Branwen 16 Jan '10

16 Jan '10

Hi everyone. So a while ago we were discussing how to improve defaults and what sorts of types and functions XM and XMC could provide which encapsulate common behavior, when Devon asked me what exactly I saw being repeated (besides the 2 or 3 examples I provided), and it occurred to me that I really didn't know. There're ~30 xmonad.hs's here <http://haskell.org/haskellwiki/Xmonad/Config_archive>, but perhaps 1/3 to 1/2 are obsolete or don't compile with darcs XM/XMC (at a very rough guess). I'd like more. So here's what I would greatly appreciate everyone doing: 1) Upload your config 2) If you've uploaded your config, update it! 3) If you use someone else's config, why not mention it? I'd appreciate knowing who's using what, so I can count the popular configurations proportionately* 4) If you don't want to do any of 1-3, perhaps you could email me privately with your config? Thanks in advance all. * I think it's fair to say that if 10 people are using a particular xmonad.hs, and there's a simplification which could be made, that change should count 10x -- gwern ANZUS nuclear Lebed .ch Domination .tm top Amherst USSS Hugo

Extensible programs & defaults: the Gosling Emacs experience
by Gwern Branwen 21 Feb '09

21 Feb '09

So, I happened to be reading a PhD thesis on exokernels, when I came across a reference. The context was that an exokernel is a maximally minimalistic operating system kernel; the kernel solely divides up resources among running programs. The programs get all other abstractions and standard OS services by linking in customized libraries, 'libOSes' as the developers put it. The point was that while an exokernel is designed so that any program can customize the operating system as much as possible, the defaults are still profoundly important, and the authors mentioned an Emacs retrospective which covered that. "UNIX Emacs: A Retrospective. Lessons for Flexible System Design" (by Gosling & Borenstein). I managed to get a copy, and I found some of it very instructive reading. Indeed, I find it instructive to look at various xmonad.hses after reading some excerpts: "The one point on which nearly everyone seems to agree is that the best thing about UNIX Emacs is that mlisp exists. No one even suggested that Emacs would be better without the powerful facility for extension and customization, although it is clear that such facilities, if abused, can create an environment that changes so radically from day to day as to be unusable for most people." "The integration of powerful editing facilities with a full-fledged programming language seems unquestionably useful, though it remains a matter of some debate whether this combination is best achieved by an extension language for a text editor or by implementing the text editor as a subroutine library in an existing programming language." "The key principle is that there is *simple syntax for simple operations*. This does not mean that a more complex syntax should not be available for more complex operations, only that the complexity should not be forced on the programmer in a simple context." "It didn't have to be that way. In the development of Emacs, it was far too easy to say that, since the support for the kind of basic interface was entirely customizable, it wasn't important to devote a lot of attention to getting the default interface to be correct. After all, anyone who didn't like the interface could change it. What this attitude ignored, however, was the old rule our mothers used to teach us about the lasting value of first impressions. Many people tried Emacs, couldn't stand the basic interface, and went back to their old standard editors, such as the vi editor on UNIX." "It is worth noting that this happened despite the fact that several people, independently, implemented more or less complete vi emulation packages for Emacs in mlisp. It seems that even if a package existed that was an absolutely perfect simulation of vi, most of the people who prefer vi to Emacs would stick with the clearly less powerful vi. While this is in part due to the smaller size of vi, it is also attributable to the unacceptable difficulty, in the minds of such people, of having to learn how to turn the vi emulation package on in the first place." "The clear lesson to be learned from this is that, while flexibility in such a system is indeed essential, great care must be paid to get the default behaviours to be simple and natural, and to provide very clear and simple ways to use a carefully chosen small set of the most commonly desired customizations. It may be, organizationally, that the people who build the flexible tools are not necessarily the right people to figure out which are the correct defaults and 'standard options'. The process of making such choices probably requires serious observation of users, or even controlled experiments, to compare possible system configurations." ----- I'm not sure how well XMonad works on the above criteria. It seems to me that there are a number of things which could be improved. For example, one of the most common changes is to switch the modifier from Alt to Win, for the simple reason that stealing Alt renders many programs nearly unusable. The arguments I've seen is that we should follow dwm tradition, and that we have no guarantee that Win is mapped to a real key, but is it really impossible for us to, say, autodetect whether Win is usable and only fallback to Alt? Or perhaps on running XMonad the first time with a xmonad.hs, there could be a prompt. Or... there are many ways we could tackle this issue. Another example: some function usages are copied all over the place. How many configurations have a line that looks like: > , keys = \c -> myKeys c `M.union` keys defaultConfig c Yes, it's neat that we can use basic Data.Map functions to union the default and custom keymaps (with the implication we can be flexible and combine them any other way we like), but it strikes me as wrong to have a relatively opaque task repeated time and again. Why don't we have a helper function such that we could write instead: > , keys = overrideDefaultWith myKeys Or if one is setting ManageHooks. Sure, one *could* write > , className =? "Firefox" --> doF (W.shift "web") 2, 3, 4, 6, or however many different entries one has in one's ManageHooks. But wouldn't a helper function be warranted so one could write: > , shiftClassToWS "Firefox" "web" For that matter, am I the only one who wants to be able to unfloat windows in ManageHook? Leaving aside how there is no actual unfloat function, I was eventually able, thanks to #xmonad, to write in my xmonad.hs: > className =? "defcon.bin.x86" --> ask >>= doF . W.sink But heck, do I understand that? Would someone else have any idea what that means? I mean, we're got 4 operators in there, 3 unusual functions (ask isn't even an xmonad function, it's from the State monad. I think. It seems a little much to expect customizers to understand monads, and the State monad, just to do a basic thing like 'unfloat an application when it opens'). ------ In short, perhaps a goal for 0.9 could be to make customizing XMonad easier on the xmonad.hs level. I think a second goal would be to change defaults in the XMonad core, and to perhaps add in some extensions by default - but that's an entirely other discussion. I'm not sure how people would react if I suggested making SmartBorders the default for the fullscreen layout. :) -- gwern Echelon Herald Islamic VHF CTP BATF POCSAG MDA USCG burhop

[xmonad-contrib] darcs patch: FocusNth again
by Aleksey P. Artamonov 20 Feb '09

20 Feb '09

As you can see I sent patch to XMonad.Actions.FocusNth last week. There were some stupid mistakes I didn't notice although these were big mistakes. Now I hope they've gone. So it's my second attempt. Please provide me with information about "state of approving". Besides, I've got a question which appeared while I was fixing mistakes in this patch. The best way to understand it is simply to simulate it by yourself. So choose a workspace with fullscreen layout. Execute one full screen program. Then one floating. Then full screen again. It would be better if you could tell both full screen apps apart easily. Now focus the application you ran most recent (let's call it A). Then focus down to the floating application. Now this floating application is really in the focus but application A has gone from the background. Instead application you ran the first is in the background. So my question is about whether it is possible to by-pass this behavior. Thanks.

xmonad-contrib patch
by Lanny Ripple 06 Feb '09

06 Feb '09

Hi all, Just wanted to say Thanks! to everyone for XMonad. I've got it running with gnome for the panels but it blows the gnome WM out of the water. I did run across some functionality I wanted that didn't exist so I wrote it up (attached). On reflection I should have added a long patch message. I found WindowGo for runOrRaise but often I want to pull a window (browser, mail, etc) to my current workspace instead of going to the one it's in. copyOrRun (and underlying copyMaybe) do that. Cheers, -ljr New patches: [XMonad.Actions.CopyWindow runOrCopy lan3ny(a)gmail.com**20080602205742] { hunk ./XMonad/Actions/CopyWindow.hs 5 --- Copyright : (c) David Roundy <droundy(a)darcs.net>, Ivan Veselov <veselov(a)gmail.com> +-- Copyright : (c) David Roundy <droundy(a)darcs.net>, Ivan Veselov <veselov(a)gmail.com>, Lanny Ripple <lan3ny(a)gmail.com> hunk ./XMonad/Actions/CopyWindow.hs 20 - copy, copyToAll, copyWindow, killAllOtherCopies, kill1 + copy, copyToAll, copyWindow, runOrCopy + , killAllOtherCopies, kill1 hunk ./XMonad/Actions/CopyWindow.hs 25 +import Control.Monad (filterM) hunk ./XMonad/Actions/CopyWindow.hs 55 +-- Instead of copying a window from a workset to a workset maybe you don't +-- want to have to remember where you placed it.

29 Jan '09

Hey List, Here's another patch. It modifies the XSelection module so you can pass a string modifying function to the promptSelect functions. This lets you run your own escape routines for various reasons. -Yaakov
