Branded string for keeping track of when we've turned an ambiguous path specified like "./blah" to an absolute path to an actual tsconfig file, e.g. "/root/blah/tsconfig.json"
SymbolTable based on ES6 Map interface.
A function that transforms a node.
A function that is used to initialize and return a Transformer callback, which in turn
will be used to transform one or more nodes.
A function that accepts and possibly transforms a node.
This represents a string whose leading underscore have been escaped by adding extra leading underscores. The shape of this brand is rather unique compared to others we've used. Instead of just an intersection of a string and an object, it is that union-ed with an intersection of void and an object. This makes it wholly incompatible with a normal string (which is good, it cannot be misused on assignment or on usage), while still being comparable with a normal string via === (also good) and castable from a string.

Adds an EmitHelper to a node.
Add EmitHelpers to a node.
Called to merge all the changes that occurred across several versions of a script snapshot into a single change. i.e. if a user keeps making successive edits to a script we will have a text change from V1 to V2, V2 to V3, ..., Vn.
This function will then merge those changes into a single change range valid between V1 and Vn.

The classifier is used for syntactic highlighting in editors via the TSServer
Create the builder that can handle the changes in program and iterate through changed files to emit the those files and manage semantic diagnostics cache as well
Create a new 'Program' instance. A Program is an immutable collection of 'SourceFile's and a 'CompilerOptions' that represent a compilation unit.
Creating a program proceeds from a set of root files, expanding the set of inputs by following imports and triple-slash-reference-path directives transitively. '@types' and triple-slash-reference-types are also pulled in.
The options for creating a program.

Iterates through the parent chain of a node and performs the callback on each parent until the callback returns a truthy value, then returns that value. If no such value is found, it applies the callback until the parent pointer is undefined or the callback returns "quit" At that point findAncestor returns undefined.
Invokes a callback for each child of the given node. The 'cbNode' callback is invoked for all child nodes stored in properties. If a 'cbNodes' callback is specified, it is invoked for embedded arrays; otherwise, embedded arrays are flattened and the 'cbNode' callback is invoked for each element. If a callback returns a truthy value, iteration stops and that value is returned. Otherwise, undefined is returned.

a callback to be invoked for all child nodes

Gets all JSDoc tags of a specified kind
Given a set of options, returns the set of type directive names that should be included for this program automatically. This list could either come from the config file, or from enumerating the types root + initial secondary types lookup location. More type directives might appear in the program later as a result of loading actual source files; this list is only the set of defaults that are implicitly included.
Gets the constant value to emit for an expression representing an enum.
Get the path of the default library files (lib.d.ts) as distributed with the typescript node package. The functionality is not supported if the ts module is consumed outside of a node module.

JavaScript file, gets the type parameters from the @template tag from JSDoc.

Gets the JSDoc type parameter tags for the node if present.
Gets the JSDoc type tag for the node if present and valid
Creates a shallow, memberwise clone of a node for mutation with its pos, end, and parent set.
NOTE: It is unsafe to change any properties of a Node that relate to its AST children, as those changes won't be
captured with respect to transformations.
Gets the original parse tree node for a node.
The original node.
The original parse tree node if found; otherwise, undefined.
Gets the original parse tree node for a node.
The original node.
A callback used to ensure the correct type of parse tree node is returned.

Return true if the node has JSDoc parameter tags.
True if has initializer node attached to it.
True if node is of a kind that may contain comment text.
Gets a value indicating whether a node originated in the parse tree.
The node to test.
True if node is of some token syntax kind. For example, this is true for an IfKeyword but not for an IfStatement. Literals are considered tokens, except TemplateLiteral, but does include TemplateHead/Middle/Tail.
True if kind is of some token syntax kind. For example, this is true for an IfKeyword but not for an IfStatement. Literals are considered tokens, except TemplateLiteral, but does include TemplateHead/Middle/Tail.
