+# HCL Dynamic Blocks Extension
+
+This HCL extension implements a special block type named "dynamic" that can
+be used to dynamically generate blocks of other types by iterating over
+collection values.
+
+Normally the block structure in an HCL configuration file is rigid, even
+though dynamic expressions can be used within attribute values. This is
+convenient for most applications since it allows the overall structure of
+the document to be decoded easily, but in some applications it is desirable
+to allow dynamic block generation within certain portions of the configuration.
+
+Dynamic block generation is performed using the `dynamic` block type:
+
+```hcl
+toplevel {
+  nested {
+    foo = "static block 1"
+  }
+
+  dynamic "nested" {
+    for_each = ["a", "b", "c"]
+    iterator = nested
+    content {
+      foo = "dynamic block ${nested.value}"
+    }
+  }
+
+  nested {
+    foo = "static block 2"
+  }
+}
+```
+
+The above is interpreted as if it were written as follows:
+
+```hcl
+toplevel {
+  nested {
+    foo = "static block 1"
+  }
+
+  nested {
+    foo = "dynamic block a"
+  }
+
+  nested {
+    foo = "dynamic block b"
+  }
+
+  nested {
+    foo = "dynamic block c"
+  }
+
+  nested {
+    foo = "static block 2"
+  }
+}
+```
+
+Since HCL block syntax is not normally exposed to the possibility of unknown
+values, this extension must make some compromises when asked to iterate over
+an unknown collection. If the length of the collection cannot be statically
+recognized (because it is an unknown value of list, map, or set type) then
+the `dynamic` construct will generate a _single_ dynamic block whose iterator
+key and value are both unknown values of the dynamic pseudo-type, thus causing
+any attribute values derived from iteration to appear as unknown values. There
+is no explicit representation of the fact that the length of the collection may
+eventually be different than one.
+
+## Usage
+
+Pass a body to function `Expand` to obtain a new body that will, on access
+to its content, evaluate and expand any nested `dynamic` blocks.
+Dynamic block processing is also automatically propagated into any nested
+blocks that are returned, allowing users to nest dynamic blocks inside
+one another and to nest dynamic blocks inside other static blocks.
+
+HCL structural decoding does not normally have access to an `EvalContext`, so
+any variables and functions that should be available to the `for_each`
+and `labels` expressions must be passed in when calling `Expand`. Expressions
+within the `content` block are evaluated separately and so can be passed a
+separate `EvalContext` if desired, during normal attribute expression
+evaluation.
+
+## Detecting Variables
+
+Some applications dynamically generate an `EvalContext` by analyzing which
+variables are referenced by an expression before evaluating it.
+
+This unfortunately requires some extra effort when this analysis is required
+for the context passed to `Expand`: the HCL API requires a schema to be
+provided in order to do any analysis of the blocks in a body, but the low-level
+schema model provides a description of only one level of nested blocks at
+a time, and thus a new schema must be provided for each additional level of
+nesting.
+
+To make this arduous process as convenient as possbile, this package provides
+a helper function `WalkForEachVariables`, which returns a `WalkVariablesNode`
+instance that can be used to find variables directly in a given body and also
+determine which nested blocks require recursive calls. Using this mechanism
+requires that the caller be able to look up a schema given a nested block type.
+For _simple_ formats where a specific block type name always has the same schema
+regardless of context, a walk can be implemented as follows:
+
+```go
+func walkVariables(node dynblock.WalkVariablesNode, schema *hcl.BodySchema) []hcl.Traversal {
+        vars, children := node.Visit(schema)
+
+        for _, child := range children {
+                var childSchema *hcl.BodySchema
+                switch child.BlockTypeName {
+                case "a":
+                        childSchema = &hcl.BodySchema{
+                                Blocks: []hcl.BlockHeaderSchema{
+                                        {
+                                                Type:       "b",
+                                                LabelNames: []string{"key"},
+                                        },
+                                },
+                        }
+                case "b":
+                        childSchema = &hcl.BodySchema{
+                                Attributes: []hcl.AttributeSchema{
+                                        {
+                                                Name:     "val",
+                                                Required: true,
+                                        },
+                                },
+                        }
+                default:
+                        // Should never happen, because the above cases should be exhaustive
+                        // for the application's configuration format.
+                        panic(fmt.Errorf("can't find schema for unknown block type %q", child.BlockTypeName))
+                }
+
+                vars = append(vars, testWalkAndAccumVars(child.Node, childSchema)...)
+        }
+}
+```
+
+### Detecting Variables with `hcldec` Specifications
+
+For applications that use the higher-level `hcldec` package to decode nested
+configuration structures into `cty` values, the same specification can be used
+to automatically drive the recursive variable-detection walk described above.
+
+The helper function `ForEachVariablesHCLDec` allows an entire recursive
+configuration structure to be analyzed in a single call given a `hcldec.Spec`
+that describes the nested block structure. This means a `hcldec`-based
+application can support dynamic blocks with only a little additional effort:
+
+```go
+func decodeBody(body hcl.Body, spec hcldec.Spec) (cty.Value, hcl.Diagnostics) {
+        // Determine which variables are needed to expand dynamic blocks
+        neededForDynamic := dynblock.ForEachVariablesHCLDec(body, spec)
+
+        // Build a suitable EvalContext and expand dynamic blocks
+        dynCtx := buildEvalContext(neededForDynamic)
+        dynBody := dynblock.Expand(body, dynCtx)
+
+        // Determine which variables are needed to fully decode the expanded body
+        // This will analyze expressions that came both from static blocks in the
+        // original body and from blocks that were dynamically added by Expand.
+        neededForDecode := hcldec.Variables(dynBody, spec)
+
+        // Build a suitable EvalContext and then fully decode the body as per the
+        // hcldec specification.
+        decCtx := buildEvalContext(neededForDecode)
+        return hcldec.Decode(dynBody, spec, decCtx)
+}
+
+func buildEvalContext(needed []hcl.Traversal) *hcl.EvalContext {
+        // (to be implemented by your application)
+}
+```
+
+# Performance
+
+This extension is going quite harshly against the grain of the HCL API, and
+so it uses lots of wrapping objects and temporary data structures to get its
+work done. HCL in general is not suitable for use in high-performance situations
+or situations sensitive to memory pressure, but that is _especially_ true for
+this extension.

+# HCL Type Expressions Extension
+
+This HCL extension defines a convention for describing HCL types using function
+call and variable reference syntax, allowing configuration formats to include
+type information provided by users.
+
+The type syntax is processed statically from a hcl.Expression, so it cannot
+use any of the usual language operators. This is similar to type expressions
+in statically-typed programming languages.
+
+```hcl
+variable "example" {
+  type = list(string)
+}
+```
+
+The extension is built using the `hcl.ExprAsKeyword` and `hcl.ExprCall`
+functions, and so it relies on the underlying syntax to define how "keyword"
+and "call" are interpreted. The above shows how they are interpreted in
+the HCL native syntax, while the following shows the same information
+expressed in JSON:
+
+```json
+{
+  "variable": {
+    "example": {
+      "type": "list(string)"
+    }
+  }
+}
+```
+
+Notice that since we have additional contextual information that we intend
+to allow only calls and keywords the JSON syntax is able to parse the given
+string directly as an expression, rather than as a template as would be
+the case for normal expression evaluation.
+
+For more information, see [the godoc reference](http://godoc.org/github.com/hashicorp/hcl2/ext/typeexpr).
+
+## Type Expression Syntax
+
+When expressed in the native syntax, the following expressions are permitted
+in a type expression:
+
+* `string` - string
+* `bool` - boolean
+* `number` - number
+* `any` - `cty.DynamicPseudoType` (in function `TypeConstraint` only)
+* `list(<type_expr>)` - list of the type given as an argument
+* `set(<type_expr>)` - set of the type given as an argument
+* `map(<type_expr>)` - map of the type given as an argument
+* `tuple([<type_exprs...>])` - tuple with the element types given in the single list argument
+* `object({<attr_name>=<type_expr>, ...}` - object with the attributes and corresponding types given in the single map argument
+
+For example:
+
+* `list(string)`
+* `object({name=string,age=number})`
+* `map(object({name=string,age=number}))`
+
+Note that the object constructor syntax is not fully-general for all possible
+object types because it requires the attribute names to be valid identifiers.
+In practice it is expected that any time an object type is being fixed for
+type checking it will be one that has identifiers as its attributes; object
+types with weird attributes generally show up only from arbitrary object
+constructors in configuration files, which are usually treated either as maps
+or as the dynamic pseudo-type.
