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>
2021-03-11 r/2276 feat(users/sterni/htmlman): static site generator for manual pagessterni5-0/+291
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.

2021-03-06 r/2273 feat(tazjin/rlox): Implement global variable definitionVincent Ambo5-15/+80
identifier_str might look a bit overengineered, but we want to reuse this bit of code and it needs a reference to the token from which to pick the identifier. The problem with this is that the token would be owned by self, but the function needs to mutate (the interner), so this implementation is the most straightforward way of acquiring and working with an immutable reference to the token before interning the identifier.

2021-03-05 r/2270 feat(users/sterni/nix/utf8): pure nix utf-8 decodersterni3-0/+332
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.

switch would probably otherwise be called match, but has been renamed so it isn't confused with string.match and the enum matching capabilities yants has. It implements the closest to pattern matching nix can come which is still flexible enough to not be painful: Syntactically it works like cond, but is given a value. Instead of booleans it checks passed predicates or equality if simple values are passed. Both types of checks can be mixed.

These aren't particularly useful without side effects, but one step at a time. This diverges slightly from the book, in that OpPop retains the last value it "forgot" from the stack in a special field on the interpreter. This makes it possible to return values from expression statements, which helps in cases where Lox is embedded as a scripting language (please don't do this ever) or in tests.

2021-03-01 r/2257 feat(users/sterni/nix): add sternis nix libsterni12-0/+811
What you see here is mostly the fallout of me implementing a correct urlencode implementation in nix for Profpatsch's blog implementation (although they'll probably keep it at arm's length). Where I want to go from here: * Extend this library towards general purpose nix™, mainly by implementing missing interfaces which you'd still have to use <nixpkgs/lib> for right now. Reexposing parts of <nixpkgs/lib> with better naming is fine for now, at some point I'd contemplate making this depend on nothing outside of depot, maybe even itself (should be easy we only use yants for an easily replaceable check). * Improve error messages possibly by carefully reintroducing yants. I originally typed essentially everything using yants, but turns out this can a) be dangerous when stuff you are handling throws because type checking means evaluating and b) has a incredible performance cost in some cases. * Reexpose builtins with better naming and slightly wrapped so they don't unrecoverably throw in cases where a null or something would suffice.
