2021-03-20 r/2295 fix(gs/achilles): Get rid of universalization stepGriffin Smith2-30/+67
The step of "universalizing" function expressions was conflicting with top-level ascriptions for polymorphic function declarations: universalization generates universal type variables, and top-level polymorphic ascription *also* generates universal type variables, and the two were conflicting with each other when unifying. Let's just get rid of this now, and we can bring it back in a more principled manner once we do actual let-generalization (which there's still an ignored test case for) Change-Id: Idc08c8cb5ac92d1e6e1e63c9b8729176cab73f44 Reviewed-on: https://cl.tvl.fyi/c/depot/+/2616 Tested-by: BuildkiteCI Reviewed-by: glittershark <grfn@gws.fyi>

2021-03-19 r/2289 fix(gs/xanthous): update xanthous.cabal, make CI catch such errorssterni3-13/+140
Since xanthous has a checked-in package.yaml and cabal file, the haskellPackages build infrastructure will use the package.yaml file for all builds. The resulting problem is that our CI won't actually catch build failures that would be observable with cabal or when building from the sdist. We fix that by filtering out the package.yaml file in pkg.nix additionally to the filters specified in .gitignore. For this we need gitignoreFilter from gitignore.nix which we expose as part of a functor set from third_party.gitignoreSource to maintain interface compatibility.

2021-03-19 r/2286 fix(gs/xanthous): fix build failures caused by dependency updatessterni7-11/+50
The following changes in dependencies of xanthous broke the build and have been fixed in this CL. Thus we can reenable CI for xanthous. * random 1.2.0 removed the Read instance for StdGen, so we need use System.Random.Internal to un-newtype StdGen into an SMGen in the appropriate places as that type still has a Show and Read instance. Requires a new direct dependency on splitmix as well. * witherable 4.0 renamed Data.Witherable into Witherable and no longer exports Filter. * random 1.2.0 probably also broke the Function instance for GameState which contains a StdGen. I'm not exactly sure which change exactly triggered this, but the fix is easy enough: We implement a Function instance for SMGen using functionShow allowing us to write a Function instance for StdGen using functionMap. I've put these instances into Xanthous.Orphans. * hgeometry 0.12.0.0 removes the triangulationEdges function (which is also not mentioned in the changelog, so I'm not sure if there's a replacement yet). Fix by pinning to 0.11.0.0 for now. * hedgehog-classes: relax bounds on semirings Change-Id: I3617d8916d753b386c9fa80062be6bcbdfee0131 Reviewed-on: https://cl.tvl.fyi/c/depot/+/2607 Tested-by: BuildkiteCI Reviewed-by: glittershark <grfn@gws.fyi>

2021-03-11 r/2277 feat(users/sterni/htmlman): hyperlink .Xr macro in outputsterni1-2/+32
We make use of the -O man=… option of mandoc(1) which allows to convert cross references via the .Xr macro into actual hyperlinks in the output. This can be disabled (by passing "none") or done in two modes: * all: links all .Xr cross references as if they were in $out/%N.%S.html. This will lead to broken links of course. * inManDir: only link to files in $out if the man page is found in manDir, use the template defined in linkXrFallback if not. all is the default, since we don't require all man pages to be in manDir, so it would be potentially confusing if the path attribute was used in the pages list. linkXrFallback uses the debian online man viewer by default currently, since it can be decently hyperlinked and debian has a lot of packages. Other options would be: * https://manpages.ubuntu.com/manpages/latest/en/man%S/%N.%S.html * https://man.archlinux.org/man/%N.%S.en * https://man.openbsd.org/%N.%S * https://www.man7.org/linux/man-pages/man%S/%N.%S.html Change-Id: I1363b9dfdda25cb7383c7310b8115c335444bd3d Reviewed-on: https://cl.tvl.fyi/c/depot/+/2597 Tested-by: BuildkiteCI Reviewed-by: sterni <sternenseemann@systemli.org>

htmlman is a very simple nix based static site generator which is intended for rendering HTML representations for man pages plus an index page listing all available pages. For the sake of simplicity (and unlike previous iterations of this piece of code) other documentation artifacts and formats are not supported. Usually web services like GitHub and depot's web interface are pretty good at displaying "normal" documentation artifacts like markdown files, but man pages are usually not rendered — with the additional problem that it's source is virtually unreadable. htmlman should provide a simple static site generator which can be plugged into GitHub actions or the like to automatically generate rendered version of man pages tracked in version control.

users.sterni.nix.utf8 implements UTF-8 decoding in pure nix. We implement the decoding as a simple state machine which is fed one byte at a time. Decoding whole strings is possible by subsequently calling step. This is done in decode which uses builtins.foldl' to get around recursion restrictions and a neat trick using builtins.deepSeq puck showed me limiting the size of the thunks in a foldl' (which can also cause a stack overflow). This makes decoding arbitrarily large UTF-8 files into codepoints using nix theoretically possible, but it is not really practical: Decoding a 36KB LaTeX file I had lying around takes ~160s on my laptop.
