type ExpressionGenerator ¶
type ExpressionGenerator interface {
// GetPrecedence returns the precedence for the indicated expression. Lower numbers bind more tightly than higher
// numbers.
GetPrecedence(expr model.Expression) int
// GenAnonymousFunctionExpression generates code for an AnonymousFunctionExpression.
GenAnonymousFunctionExpression(w io.Writer, expr *model.AnonymousFunctionExpression)
// GenBinaryOpExpression generates code for a BinaryOpExpression.
GenBinaryOpExpression(w io.Writer, expr *model.BinaryOpExpression)
// GenConditionalExpression generates code for a ConditionalExpression.
GenConditionalExpression(w io.Writer, expr *model.ConditionalExpression)
// GenForExpression generates code for a ForExpression.
GenForExpression(w io.Writer, expr *model.ForExpression)
// GenFunctionCallExpression generates code for a FunctionCallExpression.
GenFunctionCallExpression(w io.Writer, expr *model.FunctionCallExpression)
// GenIndexExpression generates code for an IndexExpression.
GenIndexExpression(w io.Writer, expr *model.IndexExpression)
// GenLiteralValueExpression generates code for a LiteralValueExpression.
GenLiteralValueExpression(w io.Writer, expr *model.LiteralValueExpression)
// GenObjectConsExpression generates code for an ObjectConsExpression.
GenObjectConsExpression(w io.Writer, expr *model.ObjectConsExpression)
// GenRelativeTraversalExpression generates code for a RelativeTraversalExpression.
GenRelativeTraversalExpression(w io.Writer, expr *model.RelativeTraversalExpression)
// GenScopeTraversalExpression generates code for a ScopeTraversalExpression.
GenScopeTraversalExpression(w io.Writer, expr *model.ScopeTraversalExpression)
// GenSplatExpression generates code for a SplatExpression.
GenSplatExpression(w io.Writer, expr *model.SplatExpression)
// GenTemplateExpression generates code for a TemplateExpression.
GenTemplateExpression(w io.Writer, expr *model.TemplateExpression)
// GenTemplateJoinExpression generates code for a TemplateJoinExpression.
GenTemplateJoinExpression(w io.Writer, expr *model.TemplateJoinExpression)
// GenTupleConsExpression generates code for a TupleConsExpression.
GenTupleConsExpression(w io.Writer, expr *model.TupleConsExpression)
// GenUnaryOpExpression generates code for a UnaryOpExpression.
GenUnaryOpExpression(w io.Writer, expr *model.UnaryOpExpression)
}
ExpressionGenerator is an interface that can be implemented in order to generate code for semantically-analyzed HCL2 expressions using a Formatter.
type Formatter ¶
type Formatter struct {
// The current indent level as a string.
Indent string
// contains filtered or unexported fields
}
Formatter is a convenience type that implements a number of common utilities used to emit source code. It implements the io.Writer interface.
func NewFormatter ¶
func NewFormatter(g ExpressionGenerator) *Formatter
NewFormatter creates a new emitter targeting the given io.Writer that will use the given ExpressionGenerator when generating code.
func (*Formatter) Fgen ¶
Fgen generates code for a list of strings and expression trees. The former are written directly to the destination; the latter are recursively generated using the appropriate gen* functions.
func (*Formatter) Fgenf ¶
Fgenf generates code using a format string and its arguments. Any arguments that are BoundNode values are wrapped in a Func that calls the appropriate recursive generation function. This allows for the composition of standard format strings with expression/property code gen (e.e. `e.genf(w, ".apply(__arg0 => %v)", then)`, where `then` is an expression tree).
