Refactor pathbind-gen from a monolithic structure into a clean modular
architecture that supports multiple generation modes (cobra CLI, terraform
provider, and future extensions) without cyclic imports or code duplication.
## Summary
This refactoring breaks up a 1291-line monolithic codebase into focused,
reusable packages:
- **pkg/types.go** (574 lines): Shared types, constants, and helper functions
used by all generation modes. Eliminates cyclic imports by having zero
reverse dependencies.
- **cobra/gen.go** (236 lines): Self-contained cobra mode generation logic,
previously mixed into main.go and cobra.go.
- **cobra/templates/**: Mode-specific templates moved from root templates/
directory, enabling each mode to have its own template namespace.
- **init.go** (144 lines): Refactored --mode=init to use shared pkg.* helpers.
- **init_openapi.go** (208 lines): OpenAPI schema walker extracted for reuse.
- **main.go** (85 lines): Pure entry point and mode dispatcher, greatly
simplified from the previous 800+ lines.
## Architecture Benefits
- **Zero cyclic imports**: pkg/ has no mode dependencies; all modes depend on pkg/
- **Unified behavior**: Types, merging logic, and utilities defined once, used
by both cobra and tf modes
- **Mode isolation**: cobra/ and [future] tf/ are completely independent packages
- **Template scalability**: Each mode has its own templates/ subdirectory
- **Bug fixes during refactoring**:
- MergedAlias now properly propagates Required and TF-specific fields
(Immutable, Computed, Sensitive, JSONEncoded) from overrides
- SortedKeys() generalized to work with any map type
## File Changes
Deleted (consolidated):
- cobra.go (713 lines → cobra/gen.go + pkg/types.go)
- types.go (70 lines → pkg/types.go)
- templates.go (12 lines → cobra/templates.go)
- templates directory structure
Modified:
- main.go: Reduced to 85-line dispatcher
- init.go: Refactored to use pkg.* types
Created:
- pkg/types.go (574 lines): All shared types and helpers
- cobra/gen.go (236 lines): Cobra generation orchestration
- cobra/templates.go (12 lines): Embed directives
- cobra/templates/ (3 templates: create, update, helpers)
- init_openapi.go (208 lines): OpenAPI schema walker
## Ready for Phase 2
TF mode implementation can now reuse:
- All pkg/types.go helpers
- Shared merge and categorization logic
- TFTemplateData struct (already defined)
## Compilation
✓ go build ./clientset/cmd/pathbind-gen succeeds
✓ No errors, warnings, or unused variables
✓ Acyclic import graph maintained

Keep cycle detection for references within the same chain while allowing

In `@clientset/cmd/pathbind-gen/pkg/types.go`:
- Around line 219-224: The mergeDraftField logic must not default unsupported or
empty consumer types to "string". Update mergeDraftField to validate the result
of goTypeToConsumer using IsSupportedConsumerType, and fail generation for
unsupported array, number, or internal "map" values unless explicit
representations are implemented; ensure Cobra does not emit "map" as a field
type while preserving Terraform’s existing map handling.
- Around line 155-165: Update LoadDraft to propagate wrapped errors from
os.ReadFile and yaml.Unmarshal instead of returning nil, using the draft path in
read and parse error messages. Preserve empty draftPath handling for
override-only Cobra mode, while ensuring supplied missing, unreadable, or
malformed paths return errors consumed by cobra.Run and tf.Run.
In `@clientset/cmd/pathbind-gen/tf/gen.go`:
- Around line 171-172: Update the type-mapping logic in the generator to use one
shared supported-type mapping for all relevant conversion paths, including the
defaults near the referenced mappings, and return a generation error when no
supported type matches instead of falling back to types.StringType. Ensure
resource.go.tmpl consumes the same mapping so unsupported or aliased Go types
cannot invoke string-specific Terraform APIs.
- Line 139: Handle the error returned by os.WriteFile in the debug-output path
instead of discarding it; only report that the unformatted output was written
after a successful write, and otherwise propagate or combine the write error
with the existing error in the surrounding generator flow.
In `@clientset/cmd/pathbind-gen/tf/templates/input.go.tmpl`:
- Line 15: Update the type selection in the input template to handle .Type equal
to "map" by emitting types.Map, matching the state templates and preserving the
existing mappings for other types.
In `@clientset/cmd/pathbind-gen/tf/templates/resource.go.tmpl`:
- Around line 179-180: Update the Sensitive handling in the resource schema
template to emit the attribute’s Sensitive boolean field set to true instead of
calling listplanmodifier.Sensitive(), mapplanmodifier.Sensitive(), or
stringplanmodifier.Sensitive(). Apply the same change to all corresponding list,
map, and string attribute branches.
- Around line 384-386: Update the resource update flow around pathbind.Expand to
fetch the current live API object first, then expand the Terraform plan into
that populated object before calling Update. Replace the empty
v1alpha1.<SDKShortType> initialization with the fetched object while preserving
existing error handling and update behavior.
- Around line 199-205: Update the resource template’s type branches to generate
PlanModifiers for Bool and Int64 attributes when planModifiers is present and
the field is Immutable, Computed, or Sensitive, using the matching
boolplanmodifier and int64planmodifier packages. Also ensure stringplanmodifier
is imported only when a String field actually emits modifiers, avoiding unused
conditional imports.
- Line 541: Update the generated assignments around native.{{.GoName}} to
validate each Terraform Int64 value is within the int32 range before converting
it; when out of range, add a diagnostic and avoid emitting the wrapped
conversion. Apply the same handling to both affected conversion sites while
preserving valid-value behavior.
- Around line 488-504: Update ImportState to invoke the handler’s PostFlatten
method on the converted state before persisting it with resp.State.Set. Keep
PostResponse immediately after pathbind.Flatten and preserve the existing
diagnostics flow, passing ctx, state, and obj to PostFlatten.
In `@clientset/cmd/pathbind-gen/tf/templates/utils_gen.go.tmpl`:
- Line 4: Update the package declaration in the utils template to use the
configured Package value, matching the resource templates, instead of hardcoding
hyperfleet.
- Around line 53-54: Update the collection conversion logic around the
len(items) checks to distinguish nil from non-nil empty slices or maps: return
the existing Terraform null value only when the collection itself is nil, and
return a known empty types.List or types.Map for non-nil empty collections.
Apply the same change to both collection-handling branches.
- Around line 151-152: Update the optional-number helper functions around the
nil checks to return nil only when the input pointer is nil; preserve non-nil
pointers even when their int32 or int64 value is zero. Apply the same behavior
to all corresponding helpers identified near the affected checks.
- Around line 70-80: The list and map conversion helpers currently discard
ElementsAs diagnostics, allowing incomplete collections to reach
pathbind.Expand. Update terraformListToStringList and terraformMapToStringMap to
return diagnostics, propagate them through the corresponding
terraform...ToNative functions, append them to resp.Diagnostics, and return
before pathbind.Expand when diagnostics are present; leave the existing
StringValue conversion paths unchanged.

Handle *string before the default branch.
When a.Type is *string, this branch generates f.StringVar(&input.Field, ...). The argument then has type **string, but StringVar requires *string. Generated code for a pointer string field will not compile.

Scope visited to the current $ref chain.
effectiveWithVisited shares visited across allOf siblings. When siblings reuse the same $ref, the first call marks it and the second call emits a false schema cycle detected warning and returns nil. The repeated reference contributes no unique leaves, so this does not cause the claimed data loss. Copy the map for each reference chain to avoid the false warning.

Propagate draft read and parse errors.
LoadDraft has an error return, but it returns nil for every os.ReadFile error and every yaml.Unmarshal error. Both cobra.Run and tf.Run already check this return, so preserve that API and return wrapped errors from LoadDraft.
An empty draftPath must remain valid for override-only Cobra mode. A supplied missing, unreadable, or malformed path must return an error.

Reject unsupported draft types instead of defaulting to string. goTypeToConsumer maps array and number to an empty type, and mergeDraftField silently changes them to string. The Cobra and Terraform generators then emit array fields such as spec.hostedCluster.networking.clusterNetwork as scalar strings.
goTypeToConsumer also returns the internal marker "map". Cobra emits that marker directly in generated input structs, producing invalid declarations such as Field map. IsSupportedConsumerType rejects "map", but neither generator calls it. Terraform has explicit map handling, so this invalid-code consequence applies to Cobra.
Fail generation when the draft type has no supported representation, or add explicit array/map representations before accepting those types. Do not use the "string" fallback.

Bounds-check Int64 values before converting them to int32.
A Terraform value outside the int32 range wraps during this conversion. The generated request can contain a different or negative value.
Validate the range before conversion and add a diagnostic when it is invalid.
As per path instructions: “Integer overflow: bounds-check user-supplied sizes.”

Use the configured package name.
tf.Run writes this file and all resource files into the same output directory. This template emits package hyperfleet, while the resource templates emit package {{.Package}}.
If config.package is not hyperfleet, Go rejects the generated directory because it contains multiple packages. Emit package {{.Package}}.

Preserve known empty collections.
An empty slice or map is distinct from a nil collection. This code converts both states to Terraform null.
If configuration contains an explicit empty list or map, refresh can write null into state and cause a perpetual diff. Return null only for nil collections. Generate a known empty types.List or types.Map for non-nil empty collections.

official Terraform Plugin Framework types List ElementsAs unknown element diagnostics behavior ListValue MapValue
💡 Result:
<search_synthesis>
In the Terraform Plugin Framework, both types.List and types.Map provide the ElementsAs method to convert their contents into standard Go types [1][2]. When dealing with potentially unknown or null elements, the framework's behavior and recommendations are as follows: Conversion Behavior and Unknown Elements The ElementsAs method converts known values into the target Go type [1][2]. If an element within a List or Map is unknown (or null), and you attempt to convert it into a standard Go primitive type (e.g., string, int, bool), the conversion will fail, resulting in diagnostics that indicate an error [3]. This occurs because standard Go primitives cannot represent the unknown or null states defined in the Terraform type system [3]. Recommended Approach To safely handle elements that may be unknown or null, HashiCorp recommends using a slice or map of framework types (such as types.String, types.Int64, etc.) as the target for the ElementsAs method instead of standard Go primitives [1][2]. For example, when extracting elements from a types.List: - Use a slice of framework types, such as []types.String, rather than []string [1]. - This allows each individual element in the collection to maintain its own IsUnknown and IsNull state, which you can then check individually after the conversion [1][2]. If you use standard Go types and encounter an unknown value, the framework will return diagnostics reflecting the inability to map that unknown value to the Go type [3]. These diagnostics can be appended to your resource or data source response to correctly report the issue to the practitioner [4]. Summary of Methods - types.ListValue and types.MapValue: Used to create known values, which are guaranteed to be fully initialized [1][2][5]. - ElementsAs: The primary method for extracting data, which handles the conversion process [1][2][3]. - IsUnknown/IsNull: Methods available on both the container (List/Map) and the individual element types (when using framework types) to check for unknown or null states [1][2][6].

Propagate ElementsAs diagnostics.
A known Terraform list or map can contain an unknown element. ElementsAs cannot represent that element in []string or map[string]string and returns an error diagnostic. These helpers discard the diagnostic, then terraform...ToNative passes the incomplete native collection to pathbind.Expand; Create or Update can therefore send an incorrect collection to the API.
Return diagnostics from these two helpers. Propagate them through terraform...ToNative, append them to resp.Diagnostics, and stop before pathbind.Expand. The ListValue and MapValue calls use only types.StringValue elements, so their diagnostics are not the reachable failure here.

Preserve explicit zero values for optional numbers.
A non-nil *int32 or *int64 already distinguishes an explicit 0 from an absent value. These helpers convert explicit zero to nil.
If a Terraform configuration sets an optional numeric field to 0, generated request or state code will omit that value. Return nil only when the pointer is nil.
