Types

type DryRunAPI 

type DryRunAPI = cmdutil.DryRunAPI

Type aliases so all existing shortcut code continues to use common.DryRunAPI without any changes. The real implementation lives in internal/cmdutil.

type DryRunAPICall 

type DryRunAPICall = cmdutil.DryRunAPICall

type Flag 

type Flag struct {
	Name     string // flag name (e.g. "calendar-id")
	Type     string // "string" (default) | "bool" | "int" | "string_array"
	Default  string // default value as string
	Desc     string // help text
	Hidden   bool   // hidden from --help, still readable at runtime
	Required bool
	Enum     []string // allowed values (e.g. ["asc", "desc"]); empty means no constraint
}

Flag describes a CLI flag for a shortcut.

type MultipartWriter 

type MultipartWriter struct {
	*multipart.Writer
}

MultipartWriter wraps multipart.Writer for file uploads.

func NewMultipartWriter 

func NewMultipartWriter(w io.Writer) *MultipartWriter

NewMultipartWriter creates a new MultipartWriter.

func (*MultipartWriter) CreateFormFile 

func (mw *MultipartWriter) CreateFormFile(fieldname, filename string) (io.Writer, error)

CreateFormFile creates a form file with the given field name and file name.

type RuntimeContext 

type RuntimeContext struct {
	Config *core.CliConfig
	Cmd    *cobra.Command
	Format string

	Factory *cmdutil.Factory // injected by framework
	// contains filtered or unexported fields
}

RuntimeContext provides helpers for shortcut execution.

func TestNewRuntimeContext 

func TestNewRuntimeContext(cmd *cobra.Command, cfg *core.CliConfig) *RuntimeContext

TestNewRuntimeContext creates a RuntimeContext for testing purposes. Only Cmd and Config are set; other fields (Factory, larkSDK, etc.) are nil.

func TestNewRuntimeContextWithCtx 

func TestNewRuntimeContextWithCtx(ctx context.Context, cmd *cobra.Command, cfg *core.CliConfig) *RuntimeContext

TestNewRuntimeContextWithCtx creates a RuntimeContext with an explicit context for tests that invoke functions which call Ctx() (e.g. HTTP request helpers).

func (*RuntimeContext) AccessToken 

func (ctx *RuntimeContext) AccessToken() (string, error)

AccessToken returns a valid access token for the current identity. For user: returns user access token (with auto-refresh). For bot: returns tenant access token.

func (*RuntimeContext) As 

func (ctx *RuntimeContext) As() core.Identity

As returns the current identity. For bot-only shortcuts, always returns AsBot. For dual-auth shortcuts, uses the resolved identity (respects default-as config).

func (*RuntimeContext) Bool 

func (ctx *RuntimeContext) Bool(name string) bool

Bool returns a bool flag value.

func (*RuntimeContext) CallAPI 

func (ctx *RuntimeContext) CallAPI(method, url string, params map[string]interface{}, data interface{}) (map[string]interface{}, error)
CallAPI uses an internal HTTP wrapper with limited control over request/response.

Prefer DoAPI for new code — it calls the Lark SDK directly and supports file upload/download options.

CallAPI calls the Lark API using the current identity (ctx.As()) and auto-handles errors.

func (*RuntimeContext) Ctx 

func (ctx *RuntimeContext) Ctx() context.Context

Ctx returns the context.Context propagated from cmd.Context().

func (*RuntimeContext) DoAPI 

func (ctx *RuntimeContext) DoAPI(req *larkcore.ApiReq, opts ...larkcore.RequestOptionFunc) (*larkcore.ApiResp, error)

DoAPI executes a raw Lark SDK request with automatic auth handling. Unlike CallAPI which parses JSON and extracts the "data" field, DoAPI returns the raw *larkcore.ApiResp — suitable for file downloads (WithFileDownload) and uploads (WithFileUpload).

Auth resolution is delegated to APIClient.DoSDKRequest to avoid duplicating the identity → token logic across the generic and shortcut API paths.

func (*RuntimeContext) DoAPIJSON 

func (ctx *RuntimeContext) DoAPIJSON(method, apiPath string, query larkcore.QueryParams, body any) (map[string]any, error)

DoAPIJSON calls the Lark API via DoAPI, parses the JSON response envelope, and returns the "data" field. Suitable for standard JSON APIs (non-file).

func (*RuntimeContext) DoAPIStream 

func (ctx *RuntimeContext) DoAPIStream(callCtx context.Context, req *larkcore.ApiReq, timeout time.Duration, opts ...larkcore.RequestOptionFunc) (*http.Response, error)

DoAPIStream executes a streaming HTTP request against the Lark OpenAPI endpoint while preserving the framework's auth resolution, shortcut headers, and security headers.

func (*RuntimeContext) IO 

func (ctx *RuntimeContext) IO() *cmdutil.IOStreams

IO returns the IOStreams from the Factory.

func (*RuntimeContext) Int 

func (ctx *RuntimeContext) Int(name string) int

Int returns an int flag value.

func (*RuntimeContext) IsBot 

func (ctx *RuntimeContext) IsBot() bool

IsBot returns true if current identity is bot.

func (*RuntimeContext) LarkSDK 

func (ctx *RuntimeContext) LarkSDK() *lark.Client

LarkSDK returns the eagerly-initialized Lark SDK client.

func (*RuntimeContext) Out 

func (ctx *RuntimeContext) Out(data interface{}, meta *output.Meta)

Out prints a success JSON envelope to stdout.

func (*RuntimeContext) OutFormat 

func (ctx *RuntimeContext) OutFormat(data interface{}, meta *output.Meta, prettyFn func(w io.Writer))

OutFormat prints output based on --format flag. "json" (default) outputs JSON envelope; "pretty" calls prettyFn; others delegate to FormatValue.

func (*RuntimeContext) PaginateAll 

func (ctx *RuntimeContext) PaginateAll(method, url string, params map[string]interface{}, data interface{}, opts client.PaginationOptions) (interface{}, error)

PaginateAll fetches all pages and returns a single merged result.

func (*RuntimeContext) RawAPI deprecated 

func (ctx *RuntimeContext) RawAPI(method, url string, params map[string]interface{}, data interface{}) (interface{}, error)

Deprecated: RawAPI uses an internal HTTP wrapper with limited control over request/response. Prefer DoAPI for new code — it calls the Lark SDK directly and supports file upload/download options.

RawAPI calls the Lark API using the current identity (ctx.As()) and returns raw result for manual error handling.

func (*RuntimeContext) Str 

func (ctx *RuntimeContext) Str(name string) string

Str returns a string flag value.

func (*RuntimeContext) StrArray 

func (ctx *RuntimeContext) StrArray(name string) []string

StrArray returns a string-array flag value (repeated flag, no CSV splitting).

func (*RuntimeContext) StreamPages 

func (ctx *RuntimeContext) StreamPages(method, url string, params map[string]interface{}, data interface{}, onItems func([]interface{}), opts client.PaginationOptions) (interface{}, bool, error)

StreamPages fetches all pages and streams each page's items via onItems. Returns the last result (for error checking) and whether any list items were found.

func (*RuntimeContext) UserOpenId 

func (ctx *RuntimeContext) UserOpenId() string

UserOpenId returns the current user's open_id from config.

type Shortcut 

type Shortcut struct {
	Service     string
	Command     string
	Description string
	Risk        string   // "read" | "write" | "high-risk-write" (empty defaults to "read")
	Scopes      []string // default scopes (fallback when UserScopes/BotScopes are empty)
	UserScopes  []string // optional: user-identity scopes (overrides Scopes when non-empty)
	BotScopes   []string // optional: bot-identity scopes (overrides Scopes when non-empty)

	// Declarative fields (new framework).
	AuthTypes []string // supported identities: "user", "bot" (default: ["user"])
	Flags     []Flag   // flag definitions; --dry-run is auto-injected
	HasFormat bool     // auto-inject --format flag (json|pretty|table|ndjson|csv)
	Tips      []string // optional tips shown in --help output

	// Business logic hooks.
	DryRun   func(ctx context.Context, runtime *RuntimeContext) *DryRunAPI // optional: framework prints & returns when --dry-run is set
	Validate func(ctx context.Context, runtime *RuntimeContext) error      // optional pre-execution validation
	Execute  func(ctx context.Context, runtime *RuntimeContext) error      // main logic
}

Shortcut represents a high-level CLI command.

func (Shortcut) Mount 

func (s Shortcut) Mount(parent *cobra.Command, f *cmdutil.Factory)

Mount registers the shortcut on a parent command.

func (*Shortcut) ScopesForIdentity 

func (s *Shortcut) ScopesForIdentity(identity string) []string

ScopesForIdentity returns the scopes applicable for the given identity. If identity-specific scopes (UserScopes/BotScopes) are set, they take precedence over the default Scopes.
