63
-- this procedure is intended to correct the Sloc field in
64
-- the first line from a line list covering a given Span.
65
-- This means, that all the fields of the Line to be corrected
66
-- have been already set as pointing to the beginning of
67
-- a given line. Together with setting the Sloc field, this
68

procedure Set_Lines (LList : in out Line_List; El : Element);
71
-- This procedure creates LList as a list of lines
72
-- accessable through El. It gets LList as a list
73
-- of Nil_Lines and makes the proper settings for
74
-- the components of each line, making them non-nil
75
-- It takes all the characteristics of these lines from El,
76
-- that is, from the tree on which El is based. This is
77
-- "tree-swapping-safe" procedure.
78
-- The only call to this procedure is in the third
79
-- Asis.Text.Lines function, which explicitly specifies
80
-- the bounds of the Line_List to be returned (that is, LList).
81
-- The caller makes all the checks needed to make sure, that
82
-- the compilation enclosing El really contains lines with numbers
83
