package go/token
MergeLine merges a line(1st parameter) with the following line. It is akin to replacing the newline character at the end of the line with a space (to not change the remaining offsets). To obtain the line number, consult e.g. Position.Line. MergeLine will panic if given an invalid line number.
Golang go/token.File.MergeLine function examples
Example 1:
if len(d.Specs) > 0 {
lastSpec := d.Specs[len(d.Specs)-1]
lastLine := fset.Position(lastSpec.Pos()).Line
if rParenLine := fset.Position(d.Rparen).Line; rParenLine > lastLine+1 {
fset.File(d.Rparen).MergeLine(rParenLine - 1) // <-- here
}
}
Example 2:
p := s.Pos()
fset.File(p).MergeLine(fset.Position(p).Line)
