Overview

Facilities to help caching the example generation. Generating examples is expensive, especially when using the convert_cli.go method that interacts with an external process. Typically provider builds first generate the schema, and then generate concrete language SDKs for Python, TypeScript and so on; these processes start from scratch as they do not easily decompose into passes, and naively they perform the conversion work multiple times. Using a file-based cache speeds up the process by avoiding repeat conversion.

Pulling out some of the repeated strings tokens into constants would harm readability, so we just ignore the goconst linter's warning.

Functions

func GenerateSchema

func GenerateSchema(info tfbridge.ProviderInfo, sink diag.Sink) (pschema.PackageSpec, error)

func LoadGoMod

func LoadGoMod() (*modfile.File, error)

func Main

func Main(pkg string, version string, prov tfbridge.ProviderInfo)

Main executes the TFGen process for the given package pkg and provider prov.

func MainWithCustomGenerate added in v3.34.0

func MainWithCustomGenerate(pkg string, version string, prov tfbridge.ProviderInfo,
	gen func(GeneratorOptions) error)

Like Main but allows to customize the generation logic past the parsing of cmd-line arguments.

Types

type ConversionError added in v3.34.0

type ConversionError struct {
	// contains filtered or unexported fields
}

A ConversionError occurs when convert.Convert yields a panic. This can be removed when https://github.com/pulumi/pulumi-terraform-bridge/issues/477 is resolved. ConversionError exposes the stacktrace of the panic so callers can choose to pass the trace along to the user or swallow it.

func (*ConversionError) Error added in v3.34.0

func (err *ConversionError) Error() string

Return the err-representation of this struct.

func (*ConversionError) StackTrace added in v3.34.0

func (err *ConversionError) StackTrace() string

StackTrace returns the stacktrace of the error.

func (*ConversionError) Unwrap added in v3.34.0

func (err *ConversionError) Unwrap() error

Unwrap provides error as returned by the conversion panic.

type CoverageTracker added in v3.6.0

type CoverageTracker struct {
	ProviderName     string                        // Name of the provider
	ProviderVersion  string                        // Version of the provider
	EncounteredPages map[string]*DocumentationPage // Map linking page IDs to their data
}

Main overarching structure for storing coverage data on how many examples were processed, how many failed, and for what reason. At different stages, the code translator notifies the tracker of what is going on. Notifications are treated as an ordered sequence of events.

NOTIFICATION INTERFACE:

example := getOrCreateExample(pageName, hcl)

languageConversionSuccess(example, targetLanguage)

languageConversionWarning(example, targetLanguage, warningDiagnostics)

languageConversionFailure(example, targetLanguage, failureDiagnostics)

languageConversionPanic(example, targetLanguage, panicInfo)

type DocFile added in v3.61.0

type DocFile struct {
	Content  []byte
	FileName string
}

type DocKind

type DocKind string

DocKind indicates what kind of entity's documentation is being requested.

const (
	// ResourceDocs indicates documentation pertaining to resource entities.
	ResourceDocs DocKind = "resources"
	// DataSourceDocs indicates documentation pertaining to data source entities.
	DataSourceDocs DocKind = "data-sources"
)

func (DocKind) String added in v3.19.2

func (k DocKind) String() string

type DocsSource added in v3.61.0

type DocsSource interface {
	// contains filtered or unexported methods
}

A source of documentation bytes.

func NewGitRepoDocsSource added in v3.61.0

func NewGitRepoDocsSource(g *Generator) DocsSource

type DocumentationPage added in v3.12.0

type DocumentationPage struct {
	Name     string    // The unique ID of this documentation page
	Examples []Example // This page's examples, stored in the order they were found
}

A structure encompassing a single page, which contains one or more examples. This closely resembles the web pages seen in Pulumi/Terraform documentation.

type Example added in v3.12.0

type Example struct {
	OriginalHCL       string                               // Original HCL code that the example was found with
	ConversionResults map[string]*LanguageConversionResult // Mapping language names to their conversion results
}

Contains information about a single example, consisting of a block of HCL and one or more language conversion results.

type GenerateOptions

type GenerateOptions struct {
	ModuleFormat string
}

type GenerateSchemaOptions added in v3.34.0

type GenerateSchemaOptions struct {
	ProviderInfo    tfbridge.ProviderInfo
	DiagnosticsSink diag.Sink
}

type GenerateSchemaResult added in v3.34.0

type GenerateSchemaResult struct {
	PackageSpec pschema.PackageSpec
}

func GenerateSchemaWithOptions added in v3.34.0

func GenerateSchemaWithOptions(opts GenerateSchemaOptions) (*GenerateSchemaResult, error)

type Generator

type Generator struct {
	// contains filtered or unexported fields
}

func NewGenerator

func NewGenerator(opts GeneratorOptions) (*Generator, error)

NewGenerator returns a code-generator for the given language runtime and package info.

func (*Generator) Generate

func (g *Generator) Generate() error

Generate creates Pulumi packages from the information it was initialized with.

func (*Generator) Sink added in v3.71.0

func (g *Generator) Sink() diag.Sink

func (*Generator) UnstableGenerateFromSchema added in v3.44.0

func (g *Generator) UnstableGenerateFromSchema(genSchemaResult *GenerateSchemaResult) error

GenerateFromSchema creates Pulumi packages from a pulumi schema and the information the generator was initialized with.

This is an unstable API. We have exposed it so other packages within pulumi-terraform-bridge can consume it. We do not recommend other packages consume this API.

type GeneratorOptions

type GeneratorOptions struct {
	Package            string
	Version            string
	Language           Language
