The Hebrew calendar is a lunisolar calendar following a Metonic cycle: every 19 years, the pattern of +//! leap years repeats. However, the precise month lengths vary from cycle to cycle: There are a handful of +//! corrections performed to ensure that: +//! +//! - The lunar conjunction happens on or before the first day of the month +//! - Yom Kippur is not before or after the Sabbath +//! - Hoshana Rabbah is not on the Sabbath +//! +//! These corrections can be done using systematic calculations, which this code attempts to efficiently perform. +//! +//! ## Molad +//! +//! A molad is the time of a conjunction, the moment when the new moon occurs. The "Molad Tishrei" is +//! the conjunction corresponding to the month Tishrei, the first month, so it is the molad that starts the new year. +//! In this file we'll typically use "molad" to refer to the molad Tishrei of a year. +//! +//! The Hebrew calendar does not always start on the day of the molad Tishrei: it may be postponed one or two days. +//! However, the time in the week that the molad occurs is sufficient to know when it gets postponed to. +//! +//! ## Keviyah +//! +//! See also: the [`Keviyah`] type. +//! +//! This is the core concept being used here. Everything you need to know about the characteristics +//! of a hebrew year can be boiled down to a notion called the "keviyah" of a year. This +//! encapsulates three bits of information: +//! +//! - What day of the week the year starts on +//! - What the month lengths are +//! - What day of the week Passover starts on. +//! +//! While this seems like many possible combinations, only fourteen of them are possible. +//! +//! Knowing the Keviyah of the year you can understand exactly what the lengths of each month are. +//! Furthermore, if you know the week the year falls in, you can additionally understand what +//! the precise day of the new year is. +//! +//! [`YearInfo`] encapsulates these two pieces of information: the [`Keviyah`] and the number of weeks +//! since the epoch of the Hebrew calendar. +//! +//! ## The Four Gates table +//! +//! This is an efficient lookup based way of calculating the [`Keviyah`] for a year. In the Metonic cycle, +//! there are four broad types of year: leap years, years preceding leap years, years succeeding leap years, +//! and years sandwiched between leap years. For each of these year types, there is a partitioning +//! of the week into seven segments, and the [`Keviyah`] of that year depends on which segment the molad falls +//! in. +//! +//! So to calculate the [`Keviyah`] of a year, we can calculate its molad, pick the right partitioning based on the +//! year type, and see where the molad falls in that table. + +use crate::helpers::i64_to_i32; +use crate::rata_die::RataDie; +use core::cmp::Ordering; + +// A note on time notation +// +// Hebrew timekeeping has some differences from standard timekeeping. A Hebrew day is split into 24 +// hours, each split into 1080 ḥalakim ("parts", abbreviated "ḥal" or "p"). Furthermore, the Hebrew +// day for calendrical purposes canonically starts at 6PM the previous evening, e.g. Hebrew Monday +// starts on Sunday 6PM. (For non-calendrical observational purposes this varies and is based on +// the sunset, but that is not too relevant for the algorithms here.) +// +// In this file an unqualified day of the week will refer to a standard weekday, and Hebrew weekdays +// will be referred to as "Hebrew Sunday" etc. Sometimes the term "regular" or "standard" will be used +// to refer to a standard weekday when we particularly wish to avoid ambiguity. +// +// Hebrew weeks start on Sunday. A common notation for times of the week looks like 2-5-204, which +// means "second Hebrew Day of the week, 5h 204 ḥal", which is 5h 204 ḥal after the start of Hebrew +// Monday (which is 23h:204ḥal on standard Sunday). +// +// Some resources will use ḥalakim notation when talking about time during a standard day. This +// document will use standard `:` notation for this, as used above with 23h:204ḥal being equal to +// 5h 204ḥal. In other words, if a time is notated using dashes or spaces, it is relative to the +// hebrew start of day, whereas if it is notated using a colon, it is relative to midnight. +// +// Finally, Adjler, the resource we are using, uses both inclusive and exclusive time notation. It +// is typical across resources using the 2-5-204 notation for the 2 to be "second day" as opposed +// to "two full days have passed" (i.e., on the first day). However *in the context of +// calculations* Adjler will use 1-5-204 to refer to stuff happening on Hebrew Monday, and clarify +// it as (2)-5-204. This is because zero-indexing works better in calculations. +// +// Comparing these algorithms with the source in Adjler should be careful about this. All other +// resources seem to universally 1-index in the dashes notation.

Build using nightly Rust and enable the [`-Zwasm-c-abi=spec`](https://doc.rust-lang.org/stable/unstable-book/compiler-flags/wasm-c-abi.html) flag. +1. Configure the JS backend to use legacy bindings. There is a [WASM ABI config option](https://github.com/rust-diplomat/diplomat/blob/main/tool/src/js/mod.rs) for this, please read [the guide on configuration in the book](https://rust-diplomat.github.io/diplomat/config) for more on how to configure. \ No newline at end of file diff --git a/deps/crates/vendor/diplomat/src/enum_convert.rs b/deps/crates/vendor/diplomat/src/enum_convert.rs new file mode 100644 index 00000000000000..0dbdad9c2f5905 --- /dev/null +++ b/deps/crates/vendor/diplomat/src/enum_convert.rs @@ -0,0 +1,87 @@ +use quote::{quote, ToTokens}; +use syn::parse::{Parse, ParseStream}; +use syn::*; + +// An attribute that is a list of idents +pub struct EnumConvertAttribute { + path: Path, + + needs_wildcard: bool, +} + +impl Parse for EnumConvertAttribute { + fn parse(input: ParseStream) -> Result { + let paths = input.parse_terminated(Path::parse, Token![,])?; + if paths.is_empty() { + return Err(input.error("#[diplomat::enum_convert] needs a path argument")); + } + let needs_wildcard = if paths.len() == 2 { + if let Some(ident) = paths[1].get_ident() { + if ident == "needs_wildcard" { + true + } else { + return Err(input.error( + "#[diplomat::enum_convert] only recognizes needs_wildcard keyword", + )); + } + } else { + return Err( + input.error("#[diplomat::enum_convert] only recognizes needs_wildcard keyword") + ); + } + } else if paths.len() > 1 { + return Err(input.error("#[diplomat::enum_convert] only supports up to two arguments")); + } else { + // no needs_wildcard marker + false + }; + Ok(EnumConvertAttribute { + path: paths[0].clone(), + needs_wildcard, + }) + } +} + +pub fn gen_enum_convert(attr: EnumConvertAttribute, input: ItemEnum) -> proc_macro2::TokenStream { + let mut from_arms = vec![]; + let mut into_arms = vec![]; + + let this_name = &input.ident; + let other_name = &attr.path; + for variant in &input.variants { + if variant.fields != Fields::Unit { + return Error::new(variant.ident.span(), "variant may not have fields") + .to_compile_error(); + } + + let variant_name = &variant.ident; + from_arms.push(quote!(#other_name::#variant_name => Self::#variant_name)); + into_arms.push(quote!(#this_name::#variant_name => Self::#variant_name)); + } + + if attr.needs_wildcard { + let error = format!( + "Encountered unknown field for {}", + other_name.to_token_stream() + ); + from_arms.push(quote!(_ => unreachable!(#error))) + } + quote! { + #[allow(deprecated)] + impl From<#other_name> for #this_name { + fn from(other: #other_name) -> Self { + match other { + #(#from_arms,)* + } + } + } + #[allow(deprecated)] + impl From<#this_name> for #other_name { + fn from(this: #this_name) -> Self { + match this { + #(#into_arms,)* + } + } + } + } +} diff --git a/deps/crates/vendor/diplomat/src/lib.rs b/deps/crates/vendor/diplomat/src/lib.rs new file mode 100644 index 00000000000000..eff4168d8b5e8a --- /dev/null +++ b/deps/crates/vendor/diplomat/src/lib.rs @@ -0,0 +1,1248 @@ +//!

With Diplomat, you can simply define Rust APIs to be exposed over FFI and get high-level C, C++, and JavaScript bindings automatically! + +Diplomat supports generating bindings from Rust to: +- C +- C++ +- Dart +- Javascript/Typescript +- Kotlin (using JNA) +- Python (using [nanobind](https://nanobind.readthedocs.io/en/latest/index.html)) + +Diplomat supports languages through a plugin interface that makes it easy to add support for your favourite language. See [the book to get started](https://rust-diplomat.github.io/diplomat/developer.html), and `tool/src/{c, cpp, js}` for examples of existing language plugins. + +## Installation +First, install the CLI tool for generating bindings: +```bash +$ cargo install diplomat-tool +``` + +Then, add the Diplomat macro and runtime as dependencies to your project: +```toml +diplomat = "0.10.0" +diplomat-runtime = "0.10.0" +``` + +## Getting Started + +Documentation on how to use Diplomat can be found [in the book](https://rust-diplomat.github.io/diplomat/). + +### Architecture +See the [design doc](docs/design_doc.md) for more details. + +### Building and Testing +Simply run `cargo build` to build all the libraries and compile an example.

This is not currently default for the `wasm32-unknown-unknown` target in the latest version of Rust, and so until the [new WASM ABI](https://blog.rust-lang.org/2025/04/04/c-abi-changes-for-wasm32-unknown-unknown/) is made stable, you have two options: + +1. Build using nightly Rust and enable the [`-Zwasm-c-abi=spec`](https://doc.rust-lang.org/stable/unstable-book/compiler-flags/wasm-c-abi.html) flag. +1. Configure the JS backend to use legacy bindings. There is a [WASM ABI config option](https://github.com/rust-diplomat/diplomat/blob/main/tool/src/js/mod.rs) for this, please read [the guide on configuration in the book](https://rust-diplomat.github.io/diplomat/config) for more on how to configure. \ No newline at end of file diff --git a/deps/crates/vendor/diplomat_core/src/ast/attrs.rs b/deps/crates/vendor/diplomat_core/src/ast/attrs.rs new file mode 100644 index 00000000000000..c44912962aa3e8 --- /dev/null +++ b/deps/crates/vendor/diplomat_core/src/ast/attrs.rs @@ -0,0 +1,519 @@ +//!

Check out the following code: +//! ```compile_fail +//! struct Foo<'a>(&'a str); +//! +//! impl<'a> Foo<'a> { +//! fn get(self) -> &str { self.0 } +//! } +//! ``` +//! This code will fail to compile because it doesn't look at the `'a` in the +//! `Foo<'a>`, which is what the type of `self` expands to. Therefore, it will +//! conclude that there's nothing for the output to borrow from. +//! This can be fixed by returning `&'a str` though. Many of the design +//! decisions in this module were made to be able to replicate this behavior. +//! +//! You may be asking "why would we care about rejecting code that rustc rejects +//! before it reaches us?" And the answer is this: +//! ```rust +//! # struct Foo<'a>(&'a str); +//! impl<'a> Foo<'a> { +//! fn get(self, s: &str) -> &str { s } +//! } +//! ``` +//! This code is accepted by rustc, since it only considers the lifetime of `s` +//! when searching for a lifetime that corresponds to output elision. If we were +//! to naively look at all the lifetimes, we would see the lifetime in the `self` +//! argument and the lifetime of `s`, making us reject this method. Therefore, we +//! have to be extremely careful when traversing lifetimes, and make sure that +//! lifetimes of `Self` are lowered but _not_ considered for elision, while other +//! lifetimes are lowered while also being considered for elision. +//! +//! # Lowering and Inference +//! +//! Lowering and elision inference is broken into three distinct stages: +//! 1. Lowering the borrow in `&self` or `&mut self`, if there is one. +//! 2. Lowering lifetimes of other params. +//! 3. Lowering lifetimes of the output. +//! +//! Although each stage fundementally lowers lifetimes, they behave differently +//! when lowering elided lifetimes. Naturally, this module represents each stage +//! as a state in a state machine. +//! +//! The first state is represented by the [`SelfParamLifetimeLowerer`] type. +//! Since there is either zero or one occurrences of `&self` or `&mut self`, it +//! exposes the `.no_self_ref()` and `.lower_self_ref(lt)` methods respectively, +//! which consume the `SelfParamLifetimeLowerer` and return the next state, +//! [`ParamLifetimeLowerer`], as well as the lowered lifetime. The reason these +//! are two distinct types is that the lifetime in `&self` and `&mut self` takes +//! precedence over any other lifetimes in the input, so `.lower_self_ref(lt)` +//! tells the next state that the candidate lifetime is already found, and to +//! generate fresh anonymous lifetimes for any elided lifetimes. +//! +//! The second state is represented by the [`ParamLifetimeLowerer`] type. +//! It implements a helper trait, [`LifetimeLowerer`], which abstracts the lowering +//! of references and generic lifetimes. Internally, it wraps an [`ElisionSource`], +//! which acts as a state machine for tracking candidate lifetimes to correspond +//! to elision in the output. When a lifetime that's not in the type of the `self` +//! argument or in the expanded generics of the `Self` type is visited, this +//! state machine is potentially updated to another state. If the lifetime is +//! anonymous, it's added to the internal list of nodes that go into the final +//! [`LifetimeEnv`] after lowering. Once all the lifetimes in the input are +//! lowered, the `into_return_ltl()` method is called to transition into the +//! final state. +//! +//! The third and final state is represented by the [`ReturnLifetimeLowerer`] type. +//! Similar to `ParamLifetimeLowerer`, it also implements the [`LifetimeLowerer`] +//! helper trait. However, it differs from `ParamLifetimeLowerer` since instead +//! of potentially updating the internal `ElisionSource` when visiting a lifetime, +//! it instead reads from it when an elided lifetime occurs. Once all the output +//! lifetimes are lowered, `.finish()` is called to return the finalized +//! [`LifetimeEnv`]. +//! +//!

Tools for traversing all borrows in method parameters and return types, shallowly +//! +//! This is useful for backends which wish to figure out the borrowing relationships between parameters +//! and return values, +//! and then delegate how lifetimes get mapped to fields to the codegen for those types respectively. +//! +//! +//! # Typical usage +//! +//! In managed languages, to ensure the GC doesn't prematurely clean up the borrowed-from object, +//! we use the technique of stashing a borrowed-from object as a field of a borrowed-to object. +//! This is called a "lifetime edge" (since it's an edge in the GC graph). An "edge array" is typically +//! a stash of all the edges on an object, or all the edges corresponding to a particular lifetime. +//! +//! This stashing is primarily driven by method codegen, which is where actual borrow relationships can be set up. +//! +//! Typically, codegen for a method should instantiate a [`BorrowedParamVisitor`] and uses it to [`BorrowedParamVisitor::visit_param()`] each input parameter to determine if it needs to be linked into an edge. +//! Whilst doing so, it may return useful [`ParamBorrowInfo`] which provides additional information on handling structs and slices. More on structs later. +//! At the end of the visiting, [`BorrowedLifetimeInfo::borrow_map()`] can be called to get a list of relevant input edges: each lifetime that participates in borrowing, +//! and a list of parameter names that it borrows from. +//! +//! This visitor will automatically handle transitive lifetime relationships as well. +//! +//! These edges should be put together into "edge arrays" which then get passed down to output types, handling transitive lifetimes as necessary. +//! +//! ## Method codegen for slices +//! +//! Slices are strange: in managed languages a host slice will not be a Rust slice, unlike other borrowed host values (a borrowed host opaque is just a borrowed Rust +//! opaque). We need to convert these across the boundary by allocating a temporary arena or something. +//! +//! If the slice doesn't participate in borrowing, this is easy: just allocate a temporary arena. However, if not, we need to allocate an arena with a finalizer (or something similar) +//! and add that arena to the edge instead. [`LifetimeEdgeKind`] has special handling for this. +//! +//! Whether or not the slice participates in borrowing is found out from the [`ParamBorrowInfo`] returned by [`BorrowedParamVisitor::visit_param()`]. +//! +//! # Method codegen for struct params +//! +//! Structs can contain many lifetimes and have relationships between them. Generally, a Diplomat struct is a "bag of stuff"; it is converted to a host value that is structlike, with fields +//! individually converted. +//! +//! Diplomat enforces that struct lifetime bounds never imply additional bounds on methods during HIR validation, so the relationships between struct +//! lifetimes are not relevant for code here (and as such you should hopefully never need to call [`LifetimeEnv::all_longer_lifetimes()`]) +//! for a struct env). +//! +//! The borrowing technique in this module allows a lot of things to be delegated to structs. As will be explained below, structs will have: +//! +//! - A `fields_for_lifetime_foo()` set of methods that returns all non-slice fields corresponding to a lifetime +//! - "append array" outparams for stashing edges when converting from host-to-Rust +//! - Some way of passing down edge arrays to individual borrowed fields when constructing Rust-to-host +//! +//! In methods, when constructing the edge arrays, `fields_for_lifetime_foo()` for every borrowed param can be appended to each +//! one whenever [`LifetimeEdgeKind::StructLifetime`] asks you to do so. The code needs to handle lifetime +//! transitivity, since the struct will not be doing so. Fortunately the edges produced by [`BorrowedParamVisitor`] already do so. +//! +//! Then, when converting structs host-to-Rust, every edge array relevant to a struct lifetime should be passed in for an append array. Append arrays +//! are nested arrays: they are an array of edge arrays. The struct will append further things to the edge array. +//! +//! Finally, when converting Rust-to-host, if producing a struct, make sure to pass in all the edge arrays. +//! +//! # Struct codegen +//! +//! At a high level, struct codegen needs to deal with lifetimes in three places: +//! +//! - A `fields_for_lifetime_foo()` set of methods that returns all non-slice fields corresponding to a lifetime +//! - "append array" outparams for stashing edges when converting from host-to-Rust +//! - Some way of passing down edge arrays to individual borrowed fields when constructing Rust-to-host +//! +//! The backend may choose to handle just slices via append arrays, or handle all borrowing there, in which case `fields_for_lifetime_foo()` isn't necessary. +//! +//! `fields_for_lifetime_foo()` should return an iterator/list/etc corresponding to each field that *directly* borrows from lifetime foo. +//! This may include calling `fields_for_lifetime_bar()` on fields that are themselves structs. As mentioned previously, lifetime relationships +//! are handled by methods and don't need to be dealt with here. There are no helpers for doing this but it's just a matter of +//! filtering for fields using the lifetime, except for handling nested structs ([`StructBorrowInfo::compute_for_struct_field()`]) +//! +//! Append arrays are similarly straightforward: for each lifetime on the struct, the host-to-Rust constructor should accept a list of edge arrays. For slice fields, +//! if the appropriate list is nonempty, the slice's arena edge should be appended to all of the edge arrays in it. These arrays should also be passed down to struct fields +//! appropriately: [`StructBorrowInfo::compute_for_struct_field()`] is super helpful for getting a list edges something should get passed down to. +//! +//! Finally, when converting Rust-to-host, the relevant lifetime edges should be proxied down to the final host type constructors who can stash them wherever needed. +//!

+ +### Details + +- A `fmt::Display` impl is generated for your enum if you provide + a docstring comment on each variant as shown above in the example. The + `Display` derive macro supports a shorthand for interpolating fields from + the error: + - `/// {var}` ⟶ `write!("{}", self.var)` + - `/// {0}` ⟶ `write!("{}", self.0)` + - `/// {var:?}` ⟶ `write!("{:?}", self.var)` + - `/// {0:?}` ⟶ `write!("{:?}", self.0)` +- This also works with structs and [generic types][crate::Display#generic-type-parameters]: +```rust +/// oh no, an error: {0} +#[derive(Display)] +pub struct Error(pub E); + +let error: Error<&str> = Error("muahaha i am an error"); +assert!("oh no, an error: muahaha i am an error" == &format!("{}", error)); +``` + +- Two optional attributes can be added to your types next to the derive: + + - `#[ignore_extra_doc_attributes]` makes the macro ignore any doc + comment attributes (or `///` lines) after the first. Multi-line + comments using `///` are otherwise treated as an error, so use this + attribute or consider switching to block doc comments (`/** */`). + + - `#[prefix_enum_doc_attributes]` combines the doc comment message on + your enum itself with the messages for each variant, in the format + “enum: variant”. When added to an enum, the doc comment on the enum + becomes mandatory. When added to any other type, it has no effect. + +- In case you want to have an independent doc comment, the + `#[displaydoc("...")` atrribute may be used on the variant or struct to + override it. + +
+ +### FAQ + +1. **Is this crate `no_std` compatible?** + * Yes! This crate implements the [`core::fmt::Display`] trait, not the [`std::fmt::Display`] trait, so it should work in `std` and `no_std` environments. Just add `default-features = false`. + +2. **Does this crate work with `Path` and `PathBuf` via the `Display` trait?** + * Yuuup. This crate uses @dtolnay's [autoref specialization technique](https://github.com/dtolnay/case-studies/blob/master/autoref-specialization/README.md) to add a special trait for types to get the display impl. It then specializes for `Path` and `PathBuf`, and when either of these types are found, it calls `self.display()` to get a `std::path::Display<'_>` type which can be used with the `Display` format specifier! + + +#### License + + +Licensed under either of Apache License, Version +2.0 or MIT license at your option. + + +

+//! +//! ## Details +//! +//! - A `fmt::Display` impl is generated for your enum if you provide +//! a docstring comment on each variant as shown above in the example. The +//! `Display` derive macro supports a shorthand for interpolating fields from +//! the error: +//! - `/// {var}` ⟶ `write!("{}", self.var)` +//! - `/// {0}` ⟶ `write!("{}", self.0)` +//! - `/// {var:?}` ⟶ `write!("{:?}", self.var)` +//! - `/// {0:?}` ⟶ `write!("{:?}", self.0)` +//! - This also works with structs and [generic types][crate::Display#generic-type-parameters]: +//! ```rust +//! # use displaydoc::Display; +//! /// oh no, an error: {0} +//! #[derive(Display)] +//! pub struct Error(pub E); +//! +//! let error: Error<&str> = Error("muahaha i am an error"); +//! assert!("oh no, an error: muahaha i am an error" == &format!("{}", error)); +//! ``` +//! +//! - Two optional attributes can be added to your types next to the derive: +//! +//! - `#[ignore_extra_doc_attributes]` makes the macro ignore any doc +//! comment attributes (or `///` lines) after the first. Multi-line +//! comments using `///` are otherwise treated as an error, so use this +//! attribute or consider switching to block doc comments (`/** */`). +//! +//! - `#[prefix_enum_doc_attributes]` combines the doc comment message on +//! your enum itself with the messages for each variant, in the format +//! “enum: variant”. When added to an enum, the doc comment on the enum +//! becomes mandatory. When added to any other type, it has no effect. +//! +//! - In case you want to have an independent doc comment, the +//! `#[displaydoc("...")` atrribute may be used on the variant or struct to +//! override it. +//! +//!
+//! +//! ## FAQ +//! +//! 1. **Is this crate `no_std` compatible?** +//! * Yes! This crate implements the [`core::fmt::Display`] trait, not the [`std::fmt::Display`] trait, so it should work in `std` and `no_std` environments. Just add `default-features = false`. +//! +//! 2. **Does this crate work with `Path` and `PathBuf` via the `Display` trait?** +//! * Yuuup. This crate uses @dtolnay's [autoref specialization technique](https://github.com/dtolnay/case-studies/blob/master/autoref-specialization/README.md) to add a special trait for types to get the display impl. It then specializes for `Path` and `PathBuf`, and when either of these types are found, it calls `self.display()` to get a `std::path::Display<'_>` type which can be used with the `Display` format specifier! +#![doc(html_root_url = "https://docs.rs/displaydoc/0.2.3")] +#![cfg_attr(docsrs, feature(doc_cfg))] +#![warn( + rust_2018_idioms, + unreachable_pub, + bad_style, + dead_code, + improper_ctypes, + non_shorthand_field_patterns, + no_mangle_generic_items, + overflowing_literals, + path_statements, + patterns_in_fns_without_body, + unconditional_recursion, + unused, + unused_allocation, + unused_comparisons, + unused_parens, + while_true +)] +#![allow(clippy::try_err)] + +#[allow(unused_extern_crates)] +extern crate proc_macro; + +mod attr; +mod expand; +mod fmt; + +use proc_macro::TokenStream; +use syn::{parse_macro_input, DeriveInput}; + +/// [Custom `#[derive(...)]` macro](https://doc.rust-lang.org/edition-guide/rust-2018/macros/custom-derive.html) +/// for implementing [`fmt::Display`][core::fmt::Display] via doc comment attributes. +/// +/// ### Generic Type Parameters +/// +/// Type parameters to an enum or struct using this macro should *not* need to +/// have an explicit `Display` constraint at the struct or enum definition +/// site.

It is often used today to track important +/// cultural events and holidays like the Chinese Lunar New Year. +/// +/// This type can be used with [`Date`] to represent dates in the Chinese calendar. +/// +/// # Months +/// +/// The Chinese calendar is an astronomical calendar which uses the phases of the moon to track months. +/// Each month starts on the date of the new moon as observed from China, meaning that months last 29 +/// or 30 days. +/// +/// One year in the Chinese calendar is typically 12 lunar months; however, because 12 lunar months does +/// not line up to one solar year, the Chinese calendar will add an intercalary leap month approximately +/// every three years to keep Chinese calendar months in line with the solar year. +/// +/// Leap months can happen after any month; the month in which a leap month occurs is based on the alignment +/// of months with 24 solar terms into which the solar year is divided. +/// +/// # Year and Era codes +/// +/// Unlike the Gregorian calendar, the Chinese calendar does not traditionally count years in an infinitely +/// increasing sequence. Instead, 10 "celestial stems" and 12 "terrestrial branches" are combined to form a +/// cycle of year names which repeats every 60 years. However, for the purposes of calendar calculations and +/// conversions, this calendar also counts years based on the ISO (Gregorian) calendar. This "related ISO year" +/// marks the ISO year in which a Chinese year begins. +/// +/// Because the Chinese calendar does not traditionally count years, era codes are not used in this calendar. +/// +/// For more information, suggested reading materials include: +/// * _Calendrical Calculations_ by Reingold & Dershowitz +/// * _The Mathematics of the Chinese Calendar_ by Helmer Aslaksen +/// * Wikipedia: +/// +/// # Month codes +/// +/// This calendar is a lunisolar calendar.
