Core MrDocs support utilities.

== Description

The public `mrdocs` namespace here centralizes assert/assume hooks so we can swap behavior (terminate, throw, debugbreak) in one place without leaking platform specifics into the rest of the codebase.

Doc‐comment enums and helpers that describe admonition kinds.

Reporting utilities (messages, statistics, sinks).

The `report` namespace owns severity enums, message structs, and output sinks so tooling and libraries emit diagnostics in a uniform, testable format regardless of UI.

== Description

This array type is used to define a dom&colon;&colon;Array whose members are evaluated on demand as they are accessed&period;

Each member can goes through a transform function before being returned as a Value so that all types can be converted to dom&colon;&colon;Value&period;

The underlying representation of the array is a range from where the elements are extracted&period; Elements in this range should be convertible to dom&colon;&colon;Value&period;

This class is typically useful for implementing arrays that are expensive and have recursive dependencies, as these recursive dependencies can also be deferred&period;

Unlike a LazyObjectImpl, which contains an overlay object, this implementation is read&hyphen;only&period; The `set` and `emplace&lowbar;back` methods are not implemented&period;

== Description

This interface is used to define objects whose members are evaluated on demand as they are accessed&period;

When any of the object properties are accessed, the object link:#mrdocs-dom-Value[`dom&colon;&colon;Value`] is constructed&period; In practice, the object never takes any memory besides the pointer to the underlying object&period;

The keys and values in the underlying object should be mapped using `tag&lowbar;invoke`&period;

This class is typically useful for implementing objects that are expensive and have recursive dependencies, as these recursive dependencies can also be deferred&period;

A context can also be stored in the object as a form to customize how the object is mapped&period; This context should be copyable and is propagated to other objects that support an overload with the same context&period;

The context can be simply a tag identifying how to map the object, or a more complex object carrying data to customize the mapping process&period;

In the latter case, because the context should be a copyable, the user might want to use a type with reference semantics&period;

== Description

This interface is used to define objects whose members are evaluated on demand as they are accessed&period;

When any of the object properties are accessed, the object link:#mrdocs-dom-Value[`dom&colon;&colon;Value`] is constructed&period; In practice, the object never takes any memory besides the pointer to the underlying object&period;

The keys and values in the underlying object should be mapped using `tag&lowbar;invoke`&period;

This class is typically useful for implementing objects that are expensive and have recursive dependencies, as these recursive dependencies can also be deferred&period;

A context can also be stored in the object as a form to customize how the object is mapped&period; This context should be copyable and is propagated to other objects that support an overload with the same context&period;

The context can be simply a tag identifying how to map the object, or a more complex object carrying data to customize the mapping process&period;

In the latter case, because the context should be a copyable, the user might want to use a type with reference semantics&period;

class Object final
----

== Description

Objects are a collection of properties, which are equivalent to key&hyphen;value pairs&period; Property values can be any type, including other Objects, allowing for the creation of arbitrarily complex data structures&period;

An Object is a non&hyphen;primitive (or reference) type, meaning that they are not copied when assigned or passed as a parameter&period; Instead, the reference is copied, and the original value is shared&period;

These reference types are modeled after JavaScript &quot;Objects&quot;&period; All non&hyphen;primitive types (Object types) are derived from Object in JavaScript&period; This means types such as Array and Function represent a relevant selection of built&hyphen;in types that would derive from Object in JavaScript&period;

== Properties

[,cpp]
----
Objects are a collection of properties, which are
equivalent to key-value pairs. There are two
kinds of properties:

@li Data properties: Associates a key with a value.
@li Accessor properties: Associates a key with
    one of two accessor functions (`get` and `set`),
    which are used to retrieve or set the value.

The internal representation of objects can determine
how properties are stored and the type of properties
being represented.

Properties can also be enumerable or non-enumerable.
An enumerable property is one that is iterated by
the `visit` function. Non-enumerable properties can
only be accessed by name with the `get` and `set`
functions.

== Description

This is the type of data stored in a Value&period; These types are loosely modeled after the JavaScript types and data structures&period;

Primitive values are Undefined, Null, Boolean, Integer, and String&period;

Undefined and Null are inhabited by a single value each&period; The difference between Undefined and Null is that Undefined is the default value for a Value, while Null represents a value that is explicitly set&period; Undefined is used to represent things such as&colon;

* An uninitialized Value
* The Value returned from a function that failed to return a value
* The result of accessing a nonexistent object property
* The result of a `find` algorithm when no element is found

This distinction is semantically important as algorithms frequently need to distinguish between these two cases&period;

Booleans, Integers, and Strings are also primitive values&period; This means they are deeply copied when assigned or passed as a parameter&period;

Other value types, such as Array, Object, and Function are reference types, meaning that they are not copied when assigned or passed as a parameter&period; Instead, the reference is copied, and the original value is shared&period;

These reference types are modeled after JavaScript &quot;Objects&quot;&period; All non&hyphen;primitive types (Object types) are derived from Object in JavaScript&period; This means types such as Array and Function represent a relevant selection of built&hyphen;in types that would derive from Object in JavaScript&period;

Objects are a collection of properties, which are equivalent to key&hyphen;value pairs&period; Property values can be any type, including other Objects, allowing for the creation of arbitrarily complex data structures&period;

== Description

This operator uses strict equality, meaning that the types must match exactly, and for objects and arrays the children must match exactly&period;

The `&equals;&equals;` operator behaves differently for objects compared to primitive data types like numbers and strings&period; When comparing objects using `&equals;&equals;`, it checks for reference equality, not structural equality&period;

This means that two objects are considered equal with `&equals;&equals;&equals;` only if they reference the exact same object in memory&period;

[NOTE]
====
In JavaScript, this is equivalent to the `&equals;&equals;&equals;` operator, which does not perform type conversions&period;

JavaScript interop helpers for the embedded runtime&period;

== Description

These functions abstract over the embedded JavaScript engine so that scripts and helpers can be bound, invoked, and marshalled without leaking engine&hyphen;specific types into the rest of the codebase&period;

&num;&num; Implementation Notes (for Python&sol;Lua integrations)

The current implementation uses JerryScript with the following design choices&colon;

&num;&num;&num; Context Isolation Each link:#mrdocs-js-Context[`Context`] owns an independent JerryScript interpreter with its own 512KB heap&period; This allows multiple threads to execute JavaScript in parallel by giving each thread its own Context&period; The `JERRY&lowbar;EXTERNAL&lowbar;CONTEXT` build flag enables this multi&hyphen;context support&period;

&num;&num;&num; Scope and Value Lifetime JerryScript uses heap&hyphen;based reference counting (not a stack like Lua&sol;Duktape)&period; To provide deterministic cleanup similar to stack&hyphen;based engines&colon;

* *Scope* tracks values created within it and releases one reference to each when the scope ends&period; Values that were copied elsewhere survive&semi; values that remained local are freed&period;
* *Value* holds its own reference via jerry&lowbar;value&lowbar;copy&sol;jerry&lowbar;value&lowbar;free&period; Values can safely outlive their creating Scope if copied&period;

&num;&num;&num; Integer Limitations JerryScript only guarantees 32&hyphen;bit integer precision&period; Values outside the int32 range (approximately &plus;&sol;&hyphen;2 billion) are converted to strings when passed to JavaScript to avoid wraparound bugs&period; When reading values back, integers that fit in int64 are returned as integers&semi; others remain as doubles&period;

&num;&num;&num; DOM to JS Conversion Strategy

* *Objects*&colon; Use lazy Proxy wrappers to avoid infinite recursion from circular references (e&period;g&period;, Handlebars symbol contexts that reference parent symbols)&period; Properties are converted on&hyphen;demand when accessed&period;
* *Arrays*&colon; Converted eagerly (snapshot semantics) because they rarely contain circular references&period; This means JS mutations don&apos;t affect the original C&plus;&plus; array and vice versa&period;
* *Functions*&colon; Wrapped bidirectionally so JS can call C&plus;&plus; functions and C&plus;&plus; can invoke JS functions through dom&colon;&colon;Function&period;

&num;&num;&num; Thread Safety Each Context has its own mutex serializing operations on that context&period; Different Contexts can execute in parallel on different threads&period; Values hold a shared&lowbar;ptr to their Context, keeping it alive and using the mutex for all JerryScript operations&period;

&num;&num;&num; Port Functions JerryScript requires &quot;port functions&quot; for platform&hyphen;specific operations&period; We use the default jerry&hyphen;port library (JERRY&lowbar;PORT&equals;ON) for most functions (logging, time, fatal errors, etc&period;), but provide custom implementations of the context management functions&colon;

* `jerry&lowbar;port&lowbar;context&lowbar;alloc`&colon; Allocates context &plus; heap memory
* `jerry&lowbar;port&lowbar;context&lowbar;free`&colon; Frees context memory
* `jerry&lowbar;port&lowbar;context&lowbar;get`&colon; Returns current thread&apos;s active context

The default jerry&hyphen;port context functions use a static global pointer, limiting all threads to a single shared context&period; When building with JERRY&lowbar;EXTERNAL&lowbar;CONTEXT&equals;ON, these functions are excluded from jerry&hyphen;port (see third&hyphen;party&sol;patches&sol;jerryscript&sol;CMakeLists&period;txt), and mrdocs provides TLS&hyphen;based implementations that allow each thread to have its own active context, enabling parallel JavaScript execution&period;

== Description

Scope serves two purposes&colon;

1&period; *Value batch tracking*&colon; Tracks JavaScript values created within the scope and releases one reference to each when the scope ends&period; Values that were copied elsewhere (e&period;g&period;, returned from functions, stored in containers) survive because they hold their own references&period; Values that remained local to the scope are freed&period;

2&period; *Thread safety*&colon; Each Scope operation briefly locks the Context&apos;s mutex and activates the context (sets TLS)&period; This allows multiple threads to share a Context while serializing access to the interpreter&period; Values obtained from a Scope can be used from other threads&semi; they will acquire the lock as needed&period;

This provides deterministic cleanup similar to stack&hyphen;based engines (Lua, Duktape) while working with JerryScript&apos;s reference&hyphen;counted heap&period;

[NOTE]
====
Multiple Scopes can exist for the same Context (even in different threads), but operations are serialized by the Context&apos;s mutex&period;

== Description

This operator uses strict equality, meaning that the types must match exactly, and for objects and arrays the children must match exactly&period;

The `&equals;&equals;` operator behaves differently for objects compared to primitive data types like numbers and strings&period; When comparing objects using `&equals;&equals;`, it checks for reference equality, not structural equality&period;

This means that two objects are considered equal with `&equals;&equals;&equals;` only if they reference the exact same object in memory&period;

[NOTE]
====
In JavaScript, this is equivalent to the `&equals;&equals;&equals;` operator, which does not perform type conversions&period;

A handlebars environment

== Synopsis

Declared in `&lt;mrdocs&sol;Support&sol;Handlebars&period;hpp&gt;`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
class Handlebars;
----

== Description

This class implements a handlebars template environment&period;

It is analogous to the complete state held by the handlebars&period;js module, including registered helpers and partials&period;

In the general case, handlebars&period;js provides a global `Handlebars` environment where helpers and partials are registered&colon;

[,cpp]
----
{.js}
      let template = Handlebars.compile("{{foo}}");
      let result = template({foo: "bar"});
----
but also provides a way to create a new isolated environment with its own helpers and partials&colon;

[,cpp]
----
{.js}
      let OtherHandlebars = Handlebars.create();
      let template = OtherHandlebars.compile("{{foo}}");
      let result = template({foo: "bar"});
----
In this implementation, however, there&apos;s no global environment&period; A new environment needs to be created explicitly be instantiating this class&colon;

[,cpp]
----
{.cpp}
      Handlebars env;
      dom::Object context;
      context["foo"] = "bar";
      std::string result = env.render("{{ foo }}", context);
      assert(result == "bar");
----
A handlebars template can be rendered using the context data provided as a `dom&colon;&colon;Value`, which is usually a `dom&colon;&colon;Object` at the first level when calling `render`&period;

In the most general case, the result can returned as a string or rendered directly to a buffer or stream&period; The render function provides an overload that allows the caller to provide an output stream where the template will be rendered directly without allocating a string&colon;

[,cpp]
----
{.cpp}
      Handlebars env;
      dom::Object context;
      context["foo"] = "bar";
      env.render_to(std::cout, "{{ foo }}", context);
      // prints "bar" to stdout
----
[,cpp]
----
{.cpp}
      Handlebars env;
      dom::Object context;
      context["foo"] = "bar";
      std::string result;
      env.render_to(result, "{{ foo }}", context);
      assert(result == "bar");
----
Design considerations&colon;

The following notes include some design considerations for the current implementation of this class&period; These are intended to describe the current state of the class rather than to provide the final specification of the class behavior&period;

Compiled templates&colon;

Unlike handlebars&period;js, this implementation renders the template directly to the output stream, without requiring an intermediary object to store a representation of the compiled template (`Handlebars&period;precompile`) or an intermediary callable object required to ultimately render the template (`Handlebars&period;precompile`)&period;

The rationale is that there is not much benefit in pre&hyphen;compiling templates in C&plus;&plus;, since both iterating the input string and a pre&hyphen;compiled template would have very similar costs even in optimal implementations of the compiled template&period;

The most significant benefit of pre&hyphen;compiling templates in C&plus;&plus; would be the faster identification of the ends of blocks, which would allow the engine iterate the block only once&period; For this reason, compiled templates will still be considered in a future version of this sub&hyphen;library&period;

Also note that compiled templates cannot avoid exceptions, because a compiled template can still invoke a helper that throws exceptions and evaluate dynamic expressions that cannot be identified during the first pass&period;

Incremental rendering and compilation&colon;

Although this is not supported by handlebars&period;js, it&apos;s common for C&plus;&plus; template engines to support incremental rendering, where the template is compiled or rendered in chunks as it is parsed&period; This implementation does not yet support this feature&period;

This is useful for streaming templates, where the template is rendered to a stream as it is parsed, without requiring the entire template to be parsed and compiled before rendering starts&period;

There are two types of incremental rendering and compilation supported by this implementation&colon;

* Incremental rendering of a partial template input to a stream
* Incremental rendering into an output buffer of fixed size

In each of these cases, the template is rendered in chunks until the end of the partial template is reached or the output buffer is full&period;

In a scenario with compiled templates, the complexity of incremental rendering needs to be implemented for both compilation and rendering&period;

The main difficulty to implement incremental rendering for handlebars&period;js is that helpers can be invoked from anywhere in the template, and most content is actually rendered by helpers&period; This means that helpers would need to be able to interoperate with whatever mechanism is designed to support suspension in this recursive&hyphen;coroutine&hyphen;like interface&period;

Error propagation&colon;

The main logic to render a template is implemented in the `render` function, does not throws by itself&period; How identifying the next tag in a template string, the algorithms uses a loose implementation where unclosed tags are rendered as&hyphen;is instead of throwing errors&period;

However, helpers are allowed to throw exceptions to propagate errors, so the `render` function is not `noexcept`&period;

For this reason, exceptions thrown by helpers are in fact exceptional conditions that should be handled by the caller&period; In general, exceptions can be avoided completely by not throwing exceptions from helpers&period;

The helper type is a type erased function of type link:#mrdocs-dom-Function[`dom&colon;&colon;Function`], which receives the resolved template arguments as parameters as a link:#mrdocs-dom-Value[`dom&colon;&colon;Value`] for each parameter&period;

The helper function also receives an object populated with variables that are accessible in the current context as its N&plus;1&hyphen;th parameter&period; This object contains information about the current context and is useful for helpers that want to change the current context or render internal blocks&period;

As all instances of link:#mrdocs-dom-Function[`dom&colon;&colon;Function`], the helper should also return a link:#mrdocs-dom-Value[`dom&colon;&colon;Value`]&period; If the function semantics does not require a return value, the function should return a link:#mrdocs-dom-Value[`dom&colon;&colon;Value`] of type link:#mrdocs-dom-Kind[`dom&colon;&colon;Kind&colon;&colon;Undefined`]&period;

== Description

Design

* If nullable&lowbar;traits&lt;T&gt; exists, the null state is encoded inside T (via sentinel or clearable&hyphen;empty semantics)&period; Storage is exactly one T&period;
* Otherwise, this falls back to std&colon;&colon;optional&lt;T&gt; and uses its discriminator&period;

This single implementation uses a conditional storage type plus if constexpr on has&lowbar;nullable&lowbar;traits&lowbar;v&lt;T&gt; to select the appropriate behavior at compile time&period;

== Description

Semantics

* The “null” (sentinel) state is any Location whose ShortPath is empty&period;
* Creating a null value produces a Location with all fields defaulted and ShortPath empty&period;
* Making an existing value null clears ShortPath and resets the other fields to their defaults&period;

Rationale

* This mirrors the old LocationEmptyPredicate, which treated an empty ShortPath as “empty&sol;null&period;”

----

== Description

This function can be used by block helpers to create child data objects&period;

The child data object is an overlay frame object implementation that will first look for a value in the child object and if not found will look in the parent object&period;

Helpers that modify the data state should create a new frame object when doing so, to isolate themselves and avoid corrupting the state of any parents&period;

Generally, only one frame needs to be created per helper execution&period; For example, the each iterator creates a single frame which is reused for all child execution&period;

parse(std::string&lowbar;view sv);
----

== Description

Parse a string view `sv` as an object of type `T`&period; If parsing fails, the function returns an error&period;

This overload does not return the `ParseResult` object containing the pointer to the first character not parsed&period; Instead, the position of the error is calculated and the error message is formatted with the error position&period;

This function parses a string view `sv` into a value of type `T`&period; The function calls the `parse` function for the type `T` with the `sv&period;data()` and `sv&period;data() &plus; sv&period;size()` as the first and last pointers, respectively&period;

If the parse function returns an error, then the function returns the error&period;

If the parse function returns success, but there are characters left in the string view, then the function returns an error with the message &quot;trailing characters&quot;&period;

Otherwise, it returns the value&period;

== Return Value

A container holding an error or a value&period;
