Functions ¶

func AllowedFieldByType ¶

func AllowedFieldByType(expr ast.Expr, pkgAlias string, imports []Import, filePath string) bool

AllowedFieldByType returns true if the field type should be treated as a simple, allowed column type. Rules: - Primitive numbers, bool, string - time.Time, []byte - Any named type that implements one of the allowed interfaces

func ImplementsAllowedInterfaces ¶

func ImplementsAllowedInterfaces(typ types.Type) bool

ImplementsAllowedInterfaces reports whether typ or *typ implements any allowed interface.

func New ¶

func New() *cobra.Command

func RenderSQLTemplate ¶

func RenderSQLTemplate(tmpl string) (string, error)

RenderSQLTemplate parses the template string and returns Go code or an error.

func ResolveTypeFromExpr ¶

func ResolveTypeFromExpr(expr ast.Expr, imports []Import, filePath string, preferAlias string) types.Type

ResolveTypeFromExpr attempts to resolve a types.Type for a field's AST expression. - Supports selector expressions (pkg.Type) - Supports identifiers from the current package (exported) - Ignores basic built-in types (lowercase idents) - Follows one level of pointers

Types ¶

type ExtractedSQL ¶

type ExtractedSQL struct {
	Raw    string
	Where  string
	Select string
}

type Field ¶

type Field struct {
	Name        string
	DBName      string
	GoType      string
	GoTypeAlias string
	Tag         string
	// contains filtered or unexported fields
}

func (Field) Type ¶

func (f Field) Type() string

Type returns the field type string for template generation

func (Field) Value ¶

func (f Field) Value() string

Value returns the field value string with column name for template generation

type File ¶

type File struct {
	Package    string
	Imports    []Import
	Interfaces []Interface
	Structs    []Struct
	Config     *genconfig.Config
	// contains filtered or unexported fields
}

func (*File) Visit ¶

func (p *File) Visit(n ast.Node) (w ast.Visitor)

Visit implements ast.Visitor to traverse AST nodes and extract imports, interfaces, and structs

type ForNode ¶

type ForNode struct {
	Expr string
	Body []Node
}

ForNode for {{for expr}}.

func (*ForNode) Emit ¶

func (fn *ForNode) Emit(indent, target string, withPrefix bool) string

type FuncNode ¶

type FuncNode struct {
	Name string
	Body []Node
}

FuncNode for {{where}} / {{set}} blocks.

func (*FuncNode) Emit ¶

func (f *FuncNode) Emit(indent, target string, withPrefix bool) string

type Generator ¶

type Generator struct {
	Files map[string]*File
	// contains filtered or unexported fields
}

func (*Generator) Gen ¶

func (g *Generator) Gen() error

Gen generates code files from processed AST data

func (*Generator) Process ¶

func (g *Generator) Process(input string) error

Process processes input files or directories and generates code

type IfBranch ¶

type IfBranch struct {
	Cond string
	Body []Node
}

IfBranch holds one condition + body.

type IfNode ¶

type IfNode struct {
	Branches []IfBranch
	ElseBody []Node
}

IfNode can have multiple branches (if, else if, else if, ...), plus an optional else.

func (*IfNode) Emit ¶

func (in *IfNode) Emit(indent, target string, withPrefix bool) string

type Import ¶

type Import struct {
	Name string
	Path string
}

func (Import) ImportPath ¶

	Interface Interface
}

func (Method) Body ¶

func (m Method) Body() string

Body generates the method body code for templates

func (Method) ParamsString ¶

func (m Method) ParamsString() string

ParamsString formats method parameters as a string for code generation

func (Method) ResultString ¶

func (m Method) ResultString() string

ResultString formats method return values as a string for code generation

type Node ¶
