Functions ¶
func FlattenStringExprAST ¶
FlattenStringExprAST recursively extracts string content from an expression tree consisting of string literals and binary '+' operations. This is the AST version that takes an already-parsed expression.
func HasNestedCall ¶
HasNestedCall returns true if any argument of the call expression is itself a call expression or contains a call expression in parentheses.
func IsCallExpr ¶
IsCallExpr returns true if s parses as a function call expression. Also matches parenthesized call expressions like (fn()).
func IsCompositeLit ¶
IsCompositeLit returns true if s parses as a composite literal. Also matches parenthesized composite literals like (T{}).
Types ¶
type OffsetSpan ¶
OffsetSpan is a half-open interval [Start, End) in byte offsets.
type OffsetSpanSet ¶
type OffsetSpanSet struct {
// contains filtered or unexported fields
}
OffsetSpanSet is a sorted, non-overlapping set of spans.
func NewOffsetSpanSet ¶
func NewOffsetSpanSet(spans []OffsetSpan) OffsetSpanSet
func OwnedSpansFromAST ¶
func OwnedSpansFromAST(file *ast.File, fset *token.FileSet, src []byte, opts OwnedSpanOptions) OffsetSpanSet
func OwnedSpansFromSource ¶
func OwnedSpansFromSource(src []byte, opts OwnedSpanOptions) OffsetSpanSet
func (OffsetSpanSet) Contains ¶
func (s OffsetSpanSet) Contains(off int) bool
Contains returns true if off falls inside any span in the set.
func (OffsetSpanSet) Overlaps ¶
func (s OffsetSpanSet) Overlaps(start, end int) bool
Overlaps reports whether any span in the set intersects the half-open interval [start, end). Intervals where end <= start are treated as empty and never overlap.
func (OffsetSpanSet) Union ¶
func (s OffsetSpanSet) Union(other OffsetSpanSet) OffsetSpanSet
Union returns a new set that contains all spans from s and other.
