Types

type BreakConfig 

type BreakConfig struct {
	// Include beta packages in breaking change detection.
	IncludeBeta bool
	// Allow stable packages to depend on beta packages.
	// This is implicitly set if IncludeBeta is set.
	AllowBetaDeps bool
}

BreakConfig is the break config.

type CompileConfig 

type CompileConfig struct {
	// The Protobuf version to use from https://github.com/protocolbuffers/protobuf/releases.
	// Must have a valid protoc zip file asset, so for example 3.5.0 is a valid version
	// but 3.5.0.1 is not.
	ProtobufVersion string
	// IncludePaths are the additional paths to include with -I to protoc.
	// Expected to be absolute paths.
	// Expected to be unique.
	IncludePaths []string
	// IncludeWellKnownTypes says to add the Google well-known types with -I to protoc.
	IncludeWellKnownTypes bool
	// AllowUnusedImports says to not error when an import is not used.
	AllowUnusedImports bool
}

CompileConfig is the compile config.

type Config 

type Config struct {
	// The directory path of the config file, or the working directory path.
	// if no config file exists.
	// Expected to be absolute path.
	DirPath string
	// The prefixes to exclude.
	// Expected to be absolute paths.
	// Expected to be unique.
	ExcludePrefixes []string
	// The compile config.
	Compile CompileConfig
	// The create config.
	Create CreateConfig
	// Lint is a special case. If nothing is set, the defaults are used. Either IDs,
	// or Group/IncludeIDs/ExcludeIDs can be set, but not both. There can be no overlap
	// between IncludeIDs and ExcludeIDs.
	Lint LintConfig
	// The break config.
	Break BreakConfig
	// The gen config.
	Gen GenConfig
}

Config is the main config.

Configs are derived from ExternalConfigs, which represent the Config in a more palpable format for configuration via a config file or flags.

String slices will be deduped and sorted if returned from this package. Configs will be validated if returned from this package.

All paths returned should be absolute paths. Outside of this package, all other internal packages should verify that all given paths are absolute, except for the internal/text package.

type ConfigProvider 

type ConfigProvider interface {
	// GetForDir tries to find a file named by one of the ConfigFilenames starting in the
	// given directory, and going up a directory until hitting root.
	//
	// The directory must be an absolute path.
	//
	// If such a file is found, it is read as an ExternalConfig and converted to a Config.
	// If no such file is found, the default config is returned.
	// If multiple files named by one of the ConfigFilenames are found in the same
	// directory, error is returned.
	GetForDir(dirPath string) (Config, error)
	// Get tries to find a file named filePath with a config.
	//
	// The path must be an absolute path.
	// The file must have either the extension .yaml or .json.
	//
	// If such a file is found, it is read as an ExternalConfig and converted to a Config.
	// If no such file is found, error is returned.
	Get(filePath string) (Config, error)
	// GetFilePathForDir tries to find a file named by one of the ConfigFilenames starting in the
	// given directory, and going up a directory until hitting root.
	//
	// The directory must be an absolute path.
	//
	// If such a file is found, it is returned.
	// If no such file is found, "" is returned.
	// If multiple files named by one of the ConfigFilenames are found in the same
	// directory, error is returned.
	GetFilePathForDir(dirPath string) (string, error)
	// GetForData returns a Config for the given ExternalConfigData in JSON format.
	// The Config will be as if there was a configuration file at the given dirPath.
	GetForData(dirPath string, externalConfigData string) (Config, error)

	// GetExcludePrefixesForDir tries to find a file named by one of the ConfigFilenames in the given
	// directory and returns the cleaned absolute exclude prefixes. Unlike other functions
	// on ConfigProvider, this has no recursive functionality - if there is no
	// config file, nothing is returned.
	// If multiple files named by one of the ConfigFilenames are found in the same
	// directory, error is returned.
	GetExcludePrefixesForDir(dirPath string) ([]string, error)
	// GetExcludePrefixesForData gets the exclude prefixes for the given ExternalConfigData in JSON format.
	// The logic will act is if there was a configuration file at the given dirPath.
	GetExcludePrefixesForData(dirPath string, externalConfigData string) ([]string, error)
}

ExternalConfig is the external representation of Config.

It is meant to be set by a YAML or JSON config file, or flags.

type GenConfig 

type GenConfig struct {
	// The go plugin options.

	// The path to the executable. For example, if the name is "grpc-cpp"
	// but the path to the executable "protoc-gen-grpc-cpp" is "/usr/local/bin/grpc_cpp_plugin",
	// then this will be "/usr/local/bin/grpc_cpp_plugin".
	// This is a function so that we defer path lookups, there is functionality where we could
	// e.g. have this point to an absolute path on the system but we don't want it for all
	// calls, for example if you have a plugin installed in a Docker image but want to run
	// prototool grpc locally.
	// We could have made this a private field and attached a function to it but this keeps
	// the style of all config structs only having public fields.
	// https://github.com/uber/prototool/issues/325
	GetPath func() (string, error) `json:"-"`
	// The type, if any. This will be GenPluginTypeNone if
	// there is no specific type.

	// Extra flags to pass.
	// If there is an associated type, some flags may be generated,
	// for example plugins=grpc or Mfile=package modifiers.
	Flags string
	// The path to output to.
	// Must be relative in a config file.
	OutputPath OutputPath
	// If set, the output path will be set to "$OUTPUT_PATH/$(basename $OUTPUT_PATH).$FILE_SUFFIX"
	// Used for e.g. JAR generation for java or descriptor_set file name.
	FileSuffix string
	// Add the --include_imports flags to protoc.
	// Only valid if Name is descriptor_set.
	IncludeImports bool

	GenPluginTypeNone GenPluginType = iota
	// GenPluginTypeGo says the plugin is a Golang plugin that
	// is or uses github.com/golang/protobuf.
	// This will use GenGoPluginOptions.
	GenPluginTypeGo
	// GenPluginTypeGogo says the plugin is a Golang plugin that

type LintConfig 

type LintConfig struct {
	// Group is the specific group of linters to use.
	// The default group is the "default" lint group, which is equal
	// to the "uber1" lint group.
	// Setting this value will result in NoDefault being ignored.
	Group string
	// NoDefault is set to exclude the default set of linters.
	// This value is ignored if Group is set.
	// Deprecated: Use group "empty" instead.

	// File paths expected to be absolute paths.
	IgnoreIDToFilePaths map[string][]string
	// FileHeader is contents of the file that contains the header for all
	// Protobuf files, typically a license header. If this is set and the
	// FILE_HEADER linter is turned on, files will be checked to begin
	// with the contents of this file, and format --fix will place this
	// header before the syntax declaration. Note that format --fix will delete
	// anything before the syntax declaration if this is set.
	FileHeader string
	// JavaPackagePrefix is the prefix for java packages. This only has an
	// effect if the linter FILE_OPTIONS_EQUAL_JAVA_PACKAGE_PREFIX is turned on.
	// This also affects create and format --fix.

}

LintConfig is the lint config.

type OutputPath 

type OutputPath struct {
	// Must be relative.
