Overview

Package plugin implements functions and types for maintaining and running stash plugins.

Stash plugins are configured using yml files in the configured plugins directory. These yml files must follow the Config structure format.

The main entry into the plugin sub-system is via the Cache type.

Functions

func FindPythonExecutable

func FindPythonExecutable() (string, error)

Types

type Cache

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

Cache stores plugin details.

func NewCache

func NewCache(config *config.Instance) *Cache

NewCache returns a new Cache.

Plugins configurations are loaded from yml files in the plugin directory in the config and any subdirectories.

Does not load plugins. Plugins will need to be loaded explicitly using ReloadPlugins.

func (Cache) CreateTask

func (c Cache) CreateTask(ctx context.Context, pluginID string, operationName string, args []*models.PluginArgInput, progress chan float64) (Task, error)

CreateTask runs the plugin operation for the pluginID and operation name provided. Returns an error if the plugin or the operation could not be resolved.

func (Cache) ExecutePostHooks

func (c Cache) ExecutePostHooks(ctx context.Context, id int, hookType HookTriggerEnum, input interface{}, inputFields []string)

func (Cache) ExecuteSceneUpdatePostHooks

func (c Cache) ExecuteSceneUpdatePostHooks(ctx context.Context, input models.SceneUpdateInput, inputFields []string)

func (Cache) ListPluginTasks

func (c Cache) ListPluginTasks() []*models.PluginTask

ListPluginTasks returns all runnable plugin tasks in all loaded plugins.

func (Cache) ListPlugins

func (c Cache) ListPlugins() []*models.Plugin

ListPlugins returns plugin details for all of the loaded plugins.

func (*Cache) LoadPlugins

func (c *Cache) LoadPlugins() error

LoadPlugins clears the plugin cache and loads from the plugin path. In the event of an error during loading, the cache will be left empty.

func (*Cache) RegisterGQLHandler

func (c *Cache) RegisterGQLHandler(handler http.Handler)

func (*Cache) RegisterSessionStore

func (c *Cache) RegisterSessionStore(sessionStore *session.Store)

type Config

type Config struct {

	// The name of the plugin. This will be displayed in the UI.
	Name string `yaml:"name"`

	// An optional description of what the plugin does.
	Description *string `yaml:"description"`

	// An optional URL for the plugin.
	URL *string `yaml:"url"`

	// An optional version string.
	Version *string `yaml:"version"`

	// The communication interface used when communicating with the spawned
	// plugin process. Defaults to 'raw' if not provided.
	Interface interfaceEnum `yaml:"interface"`

	// The command to execute for the operations in this plugin. The first
	// element should be the program name, and subsequent elements are passed
	// as arguments.
	//
	// Note: the execution process will search the path for the program,
	// then will attempt to find the program in the plugins
	// directory. The exe extension is not necessary on Windows platforms.
	// The current working directory is set to that of the stash process.
	Exec []string `yaml:"exec,flow"`

	// The default log level to output the plugin process's stderr stream.
	// Only used if the plugin does not encode its output using log level
	// control characters.
	// See package common/log for valid values.
	// If left unset, defaults to log.ErrorLevel.
	PluginErrLogLevel string `yaml:"errLog"`

	// The task configurations for tasks provided by this plugin.
	Tasks []*OperationConfig `yaml:"tasks"`

	// The hooks configurations for hooks registered by this plugin.
	Hooks []*HookConfig `yaml:"hooks"`
	// contains filtered or unexported fields
}

Config describes the configuration for a single plugin.

type GalleryDestroyInput

type GalleryDestroyInput struct {
	models.GalleryDestroyInput
	Checksum string `json:"checksum"`
	Path     string `json:"path"`
}

type HookConfig

	// A list of stash operations that will be used to trigger this hook operation.
	TriggeredBy []HookTriggerEnum `yaml:"triggeredBy"`
}

type HookTriggerEnum

type HookTriggerEnum string

	// A short description of the operation. This description is shown below
	// the button in the UI.

	// A list of arguments that will be appended to the plugin's Exec arguments
	// when executing this operation.

type SceneDestroyInput struct {
	models.SceneDestroyInput
	Checksum string `json:"checksum"`
	OSHash   string `json:"oshash"`

type Task

type Task interface {
	// Start starts the plugin task. Returns an error if task could not be
	// started or the task has already been started.

	// Stop instructs a running plugin task to stop and returns immediately.
	// Use Wait to subsequently wait for the task to stop.
	Stop() error

	// Wait blocks until the plugin task is complete. Returns immediately if
	// task has not been started.
	Wait()

	// GetResult returns the output of the plugin task. Returns nil if the task
	// has not completed.
	GetResult() *common.PluginOutput
}

Task is the interface that handles management of a single plugin task.
