* Enforce the U+0000 to U+10FFFF range in `count` and throw an error if the given codepoint exceeds the range (encoding U+0000 won't work of course, but this is Nix's fault…). * Check if the produced bytes are well formed and output an error if not. This indicates that the codepoint can't be encoded as UTF-8, like U+D800 which is reserved for UTF-16. Change-Id: I18336e527484580f28cbfe784d51718ee15c5477

Previously we would check the first byte only when trying to figure out the predicate for the second byte. If the first byte was invalid, we'd then throw with a helpful error message. However this made wellFormedByte a very weird function. At the expense of doing the same check twice, we now check the first byte, when it is first passed, and always return a boolean.

2021-11-23 r/3085 refactor(sterni/nix/utf8): use genericClosure for decoding iterationsterni1-23/+46
builtins.genericClosure is a quite powerful (and undocumented) Nix primop: It repeatedly applies a function to values it produces and collects them into a list. Additionally individual results can be identified via a key attribute. Since genericClosure only ever creates a single list value internally, we can eliminate a huge performance bottleneck when building a list in a recursive algorithm: list concatenation. Because Nix needs to copy the entire chunk of memory used internally to represent the list, building big lists one element at a time grinds Nix to a halt. After rewriting decode using genericClosure decoding the LaTeX source of my 20 page term paper now takes 2s instead of 14min. Change-Id: I33847e4e7dd95d7f4d78ac83eb0d74a9867bfe80

2021-09-12 r/2854 feat(sterni/mblog): convert apple note mime msgs to htmlsterni5-0/+250
For now mblog only contains the mnote-html executable which takes a mime message from a maildir and prints the equivalent HTML fragment to stdout. It is intended to work with the mblaze(7) utilities, i. e. mnote-html resolves all `object` tags to proper `img` inclusions with the correct filename, so mshow(1)'s -x version can supply the needed image files. A note created using Apple's Notes app (tested with the iOS version) can be converted in a viewable HTML file like this: $ mnote-html path/to/msg > fragment.html $ mshow -x path/to/msg $ cat <(echo "<!DOCTYPE html>") fragment.html > document.html $ xdg-open document.html Note that only the limited feature set of Apple Notes when using the IMAP backend is supported. The iCloud-based one has more (quite neat) features, but its notes can only accessed via an internal API as far as I know. This CLI is a bit impractical due to the big startup overhead of loading the lisp image. mblog should be become a fully fletched static site generator in the future, but this is a good starting point and providing the mnote-html tool is certainly useful.

2021-08-24 r/2771 feat(nix/buildLisp): add eclsterni1-1/+4
Adds ECL as a second supported implementation, specifically a statically linked ECL. This is interesting because we can create statically linked binaries, but has a few drawbacks which doesn't make it generally useful: * Loading things is very slow: The statically linked ECL only has byte compilation available, so when we do load things or use the REPL it is significantly worse than with e. g. SBCL. * We can't load shared objects via the FFI since ECL's dffi is not available when linked statically. This means that as it stands, we can't build a statically linked //web/panettone for example. Since ECL is quite slow anyways, I think these drawbacks are worth it since the biggest reason for using ECL would be to get a statically linked binary. If we change our minds, it shouldn't be too hard to provide ecl-static and ecl-dynamic as separate implementations. ECL is LGPL and some libraries it uses as part of its runtime are as well. I've outlined in the ecl-static overlay why this should be of no concern in the context of depot even though we are statically linking. Currently everything is building except projects that are using cffi to load shared libaries which have gotten an appropriate `badImplementations` entry. To get the rest building the following changes were made: * Anywhere a dependency on UIOP is expressed as `bundled "uiop"` we now use `bundled "asdf"` for all implementations except SBCL. From my testing, SBCL seems to be the only implementation to support using `(require 'uiop)` to only load the UIOP package. Where both a dependency on ASDF and UIOP exists, we just delete the UIOP one. `(require 'asdf)` always causes UIOP to be available. * Where appropriate only conditionally compile SBCL-specific code and if any build the corresponding files for ECL. * //lisp/klatre: Use the standard condition parse-error for all implementations except SBCL in try-parse-integer. * //3p/lisp/ironclad: disable SBCL assembly optimization hack for all other platforms as it may interfere with compilation. * //3p/lisp/trivial-mimes: prevent call to asdf function by substituting it out of the source since it always errors out in ECL and we hardcode the correct path elsewhere anyways. As it stands ECL still suffers from a very weird problem which happens when compiling postmodern and moptilities: https://gitlab.com/embeddable-common-lisp/ecl/-/issues/651 Change-Id: I0285924f92ac154126b4c42145073c3fb33702ed Reviewed-on: https://cl.tvl.fyi/c/depot/+/3297 Tested-by: BuildkiteCI Reviewed-by: tazjin <mail@tazj.in> Reviewed-by: eta <tvl@eta.st>

2021-04-01 r/2393 feat(sterni/nint): shebang interpreter for nix scriptssterni3-0/+244
nint (short for nix interpreter) is a tiny wrapper around nix-instantiate which allows to run nix scripts, i. e. nix expressions that conform to a certain calling convention. A nix script runnable using nint must conform to the following constraints: * It must evaluate to a function which has a set pattern with an ellipsis as the single argument. * It must produce a string as a return value or fail. When invoked, a the expression receives the following arguments: * `currentDir`: the current working directory as a nix path * `argv`: a list of strings containing `argv` including `argv[0]` * extra arguments which are manually specified which allows for passing along dependencies or libraries, for example: nint --arg depot '(import /depot {})' my-prog.nix [ argv[1] … ] would pass along depot to be used in `my-prog.nix`. Such nix scripts are purely functional in a sense: The way inputs can be taken is very limited and causing effects is also only possible in a very limited sense (using builtins.fetchurl if TARBALL_TTL is 0, adding files and directories to the nix store, realising derivations). As an approximation, a program executed using nint can be thought of as a function with the following signature: λ :: environment → working directory → argv → stdout where environment includes: * the time at the start of the program (`builtins.currentTime`) * other information about the machine (`builtins.currentSystem` …) * environment variables (`builtins.getEnv`) * the file system (`builtins.readDir`, `builtins.readFile`, …) which is the biggest input impurity as it may change during evaluation Additionally import from derivation and builtin fetchers are available which introduce further impurities to be utilized. Future work: * Streaming I/O via lazy lists. This would allow usage of stdin and output before the program terminates. However this would require using libexpr directly or writing a custom nix interpreter. A description of how this would work can be found on the website of the esoteric programming language Lazy K: https://tromp.github.io/cl/lazy-k.html * An effect system beyond stdin / stdout. * Better error handling, support setting exit codes etc. These features would require either using an alternative or custom interpreter for nix (tvix or hnix) or to link against libexpr directly to have more control over evaluation.

We use builtins.split directly as it should be a bit more efficient as lib.splitStrings. Also its returning of a list for every regex match is useful to update the state while parsing the tokens: * The tokens are obtained by splitting the string at every '%' * Everytime we see a boundary (that is a list in the returned list of builtins.split), we know that the first two chars of the next string are a percent encoded character. One implementation flaw is that it will currently crash if it encounters mal-formed URLs (since int.fromHex chrashes if it encounters any non hex digit characters) and accepts some malformed urlencoding like "foo %A".

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 pagessterni3-0/+289
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.

2021-03-05 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.

2021-03-05 r/2269 feat(users/sterni/nix/flow): add switch conditionalsterni1-23/+53
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.

Since nix ends the substring at the end of the string anyways we can just statically use the largest nix integer as the length of the string. According to my testing this it ever so slightly faster as well.

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.

This way ci should pick up on clhs-lookup since only a single derivation is exposed with the default.nix and it is less cumbersome to type the attribute path (users.sterni.clhs.clhs-lookup → users.sterni.clhs-lookup). The exposed CLHS wasn't used for anything anyways and I can always expose it again using passthru or extra if it's ever merged.
