Functions

func LoadCachedContent 

func LoadCachedContent(dataDir string, book Book, chapter Chapter) (string, error)

func MatchAlternativeChapter 

func MatchAlternativeChapter(chapters []Chapter, previousTitle string, previousIndex int) (index int, matched bool)

MatchAlternativeChapter uses only unique matches. When no reliable title or chapter number exists, the caller must disclose that the clamped index is an approximation rather than an identified chapter.

func NormalizeContent 

func NormalizeContent(text string) string

NormalizeContent converts common HTML fragments to readable chapter text. Unknown angle-bracket words are preserved; this is not an HTML sanitizer. Entity decoding is bounded to three layers for escaped source responses.

func SaveCachedChapters 

func SaveCachedChapters(dataDir string, book Book, chapters []Chapter) error

func SaveCachedContent 

func SaveCachedContent(dataDir string, book Book, chapter Chapter, content string) error

func SaveSources 

func SaveSources(dataDir string, sources []Source) error

func ValidateSource 

func ValidateSource(source Source) error

Types

type AlternativeResult 

type AlternativeResult struct {

}

func LoadCachedChapters 

func LoadCachedChapters(dataDir string, book Book) ([]Chapter, error)

type Client 

type Client struct {
	HTTPClient       *http.Client
	MaxResponseBytes int64
	MaxPages         int
	// contains filtered or unexported fields
}

func NewClient 

func NewClient() *Client

func (*Client) BookInfo 

func (c *Client) BookInfo(ctx context.Context, source Source, book Book) (Book, error)

func (*Client) Chapters 

func (c *Client) Chapters(ctx context.Context, source Source, book Book) ([]Chapter, error)

func (*Client) Content 

func (c *Client) Content(ctx context.Context, source Source, book Book, chapter Chapter) (string, error)

func (*Client) FindAlternatives 

func (c *Client) FindAlternatives(ctx context.Context, sources []Source, current Book, page int) (AlternativeResult, error)

FindAlternatives searches every enabled, searchable text source. Candidate order follows the source order, then the order returned by each source.

func (*Client) Import 

func (c *Client) Import(ctx context.Context, location string) ([]Source, error)

func (*Client) IsLoggedIn 

func (c *Client) IsLoggedIn(src Source) bool

func (*Client) LoadSessions 

func (c *Client) LoadSessions(dir string) error

func (*Client) Login 

func (c *Client) Login(ctx context.Context, src Source, fields map[string]string) error

Login supports the declared 大灰狼 API profile and manual website cookies. Credentials are scoped to one explicitly declared API origin, are never passed to source JavaScript and are never written to the session file.

func (*Client) LoginStatus 

func (c *Client) LoginStatus(src Source) bool

func (*Client) Logout 

func (c *Client) Logout(src Source) error

func (*Client) SaveSessions 

func (c *Client) SaveSessions(dir string) error

func (*Client) Search 

func (c *Client) Search(ctx context.Context, source Source, keyword string, page int) ([]Book, error)

type ContentRule 

type ContentRule struct {
	Content        string `json:"content"`
	NextContentURL string `json:"nextContentUrl,omitempty"`
	ReplaceRegex   string `json:"replaceRegex,omitempty"`
}

type Evaluator 

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

Evaluator implements the portable subset of Legado's source rule language. Each JavaScript invocation has its own VM; put/get variables are shared by this evaluator. Selectors return detached values or HTML nodes for chaining.

func NewEvaluator 

func NewEvaluator(baseURL string, variables map[string]any) *Evaluator

func (*Evaluator) Elements 

func (e *Evaluator) Elements(input any, rule string) ([]any, error)

func (*Evaluator) EvalJS 

func (e *Evaluator) EvalJS(code string, result any) (output any, evalErr error)

EvalJS exposes only portable helpers and explicitly granted JS bindings. Android/Rhino-specific APIs fail at the point of use with a named error.

func (*Evaluator) SetJSBindings 

func (e *Evaluator) SetJSBindings(bindings map[string]any) *Evaluator

SetJSBindings explicitly grants scripts trusted application capabilities. A java map augments the built-in helpers. Callers must bound any blocking native function (for example with HTTP context deadlines); VM interruption cannot preempt a Go function. Treat the supplied maps as immutable.

func (*Evaluator) SetJSContext 

func (e *Evaluator) SetJSContext(ctx context.Context) *Evaluator

SetJSContext binds script execution to the request lifetime. Native bindings must use this same request context for their own blocking operations.

func (*Evaluator) SetJSLib 

func (e *Evaluator) SetJSLib(code string) *Evaluator

func (*Evaluator) SetJSTimeout 

func (e *Evaluator) SetJSTimeout(timeout time.Duration) *Evaluator

func (*Evaluator) String 

func (e *Evaluator) String(input any, rule string) (string, error)

func (*Evaluator) Strings 

func (e *Evaluator) Strings(input any, rule string) ([]string, error)

type LoginField 

type LoginField struct {
	Name   string
	Secret bool
}

LoginField describes an input supported by this client. Script buttons that register accounts, purchase content or change server settings are not run.

func LoginFields 

func LoginFields(src Source) []LoginField

func LoginUIFields 

func LoginUIFields(src Source) []LoginField

type Source 

type Source struct {
	LoginURL     string                     `json:"loginUrl,omitempty"`
	LoginUI      json.RawMessage            `json:"loginUi,omitempty"`
	LoginCheckJS string                     `json:"loginCheckJs,omitempty"`
	Extra        map[string]json.RawMessage `json:"-"`
	URL          string                     `json:"bookSourceUrl"`
	Name         string                     `json:"bookSourceName"`
	Group        string                     `json:"bookSourceGroup,omitempty"`
	Type         int                        `json:"bookSourceType"`
	Enabled      *bool                      `json:"enabled,omitempty"`
	Header       json.RawMessage            `json:"header,omitempty"`
	JSLib        string                     `json:"jsLib,omitempty"`
	SearchURL    string                     `json:"searchUrl"`
	Search       BookRule                   `json:"ruleSearch"`
	BookInfo     BookRule                   `json:"ruleBookInfo"`
	TOC          TOCRule                    `json:"ruleToc"`
	Content      ContentRule                `json:"ruleContent"`
}

func Import 

func Import(ctx context.Context, location string) ([]Source, error)

Import accepts a UTF-8 JSON file or HTTP(S) URL. Malformed entries are reported with their array position. Valid unsupported sources are retained disabled so an imported collection can round-trip without losing entries.

func LoadSources 

func LoadSources(dataDir string) ([]Source, error)

func MergeSources 

func MergeSources(existing, incoming []Source) []Source

func (Source) IsEnabled 

func (s Source) IsEnabled() bool

func (Source) MarshalJSON 

func (s Source) MarshalJSON() ([]byte, error)

func (*Source) UnmarshalJSON 

func (s *Source) UnmarshalJSON(data []byte) error

Some source exports serialize individual rule objects as JSON strings.

type TOCRule 

type TOCRule struct {
	ChapterList string `json:"chapterList"`
	ChapterName string `json:"chapterName"`
	ChapterURL  string `json:"chapterUrl"`
	NextTOCURL  string `json:"nextTocUrl,omitempty"`
	IsVolume    string `json:"isVolume,omitempty"`
}
