Specifically, +-- check the subprograms Append, Delete, Index, Insert , Length, +-- Overwrite, Replace_Slice, Slice, "&", To_Bounded_Wide_String, +-- To_Wide_String, Translate, and Trim. +-- +-- TEST DESCRIPTION: +-- This test demonstrates the uses of a variety of the Wide_String +-- functions found in the package Ada.Strings.Wide_Bounded, simulating +-- the operations found in a text processing environment. +-- With bounded wide strings, the length of each "line" of text can vary +-- up to the instantiated maximum, allowing one to view a page of text as +-- a series of expandable lines. This provides flexibility in text +-- formatting of individual lines (wide strings). +-- Several subprograms are defined, all of which attempt to take +-- advantage of as many different bounded wide string utilities as +-- possible. Often, an operation that is being performed in a subprogram +-- using a certain bounded wide string utility could more efficiently be +-- performed using a different utility. However, in the interest of +-- including as broad coverage as possible, a mixture of utilities is +-- invoked in this test. +-- A simulated page of text is provided as a parameter to the test +-- defined subprograms, and the appropriate processing performed. The +-- processed page of text is then compared to a predefined "finished" +-- page, and test passage/failure is based on the results of this +-- comparison. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- 06 Nov 95 SAIC Corrected initialization error for ACVC 2.0.1. +-- +--! + +with Ada.Strings; +with Ada.Strings.Wide_Bounded; +with Ada.Strings.Wide_Maps; +with Report; + +procedure CXA4017 is + +begin + + Report.Test ("CXA4017", "Check that the subprograms defined in package " & + "Ada.Strings.Wide_Bounded are available, and " & + "that they produce correct results"); + + Test_Block: + declare + + Characters_Per_Line : constant Positive := 40; + Lines_Per_Page : constant Natural := 4; + + + package BS_40 is new + Ada.Strings.Wide_Bounded.Generic_Bounded_Length(Characters_Per_Line); + + use type BS_40.Bounded_Wide_String; + + type Page_Type is array (1..Lines_Per_Page) of + BS_40.Bounded_Wide_String; + + -- Note: Misspellings below are intentional. + + Line1 : BS_40.Bounded_Wide_String := + BS_40.To_Bounded_Wide_String + ("ada is a progrraming language designed"); + Line2 : BS_40.Bounded_Wide_String := + BS_40.To_Bounded_Wide_String("to support the construction of long-"); + Line3 : BS_40.Bounded_Wide_String := + BS_40.To_Bounded_Wide_String("lived, highly reliabel software "); + Line4 : BS_40.Bounded_Wide_String := + BS_40.To_Bounded_Wide_String("systems"); + + Page : Page_Type := (1 => Line1, 2 => Line2, 3 => Line3, 4 => Line4); + + Finished_Page : Page_Type := + (BS_40.To_Bounded_Wide_String + ("Ada is a programming language designed"), + BS_40.To_Bounded_Wide_String("to support the construction of long-"), + BS_40.To_Bounded_Wide_String + ("lived, HIGHLY RELIABLE software systems."), + BS_40.To_Bounded_Wide_String("")); + + --- + + procedure Compress (Page : in out Page_Type) is + Clear_Line : Natural := Lines_Per_Page; + begin + -- If two consecutive lines on the page are together less than the + -- maximum line length, then append those two lines, move up all + -- lower lines on the page, and blank out the last line. + -- This algorithm works one time through the page, does not perform + -- repetitive compression, and is designed for use with this test + -- program only. + for i in 1..Lines_Per_Page - 1 loop + if BS_40.Length(Page(i)) + BS_40.Length(Page(i+1)) <= + BS_40.Max_Length + then + Page(i) := BS_40."&"(Page(i), + Page(i+1)); -- "&" (wd bnd, wd bnd) + + for j in i+1..Lines_Per_Page - 1 loop + Page(j) := + BS_40.To_Bounded_Wide_String + (BS_40.Slice(Page(j+1), + 1, + BS_40.Length(Page(j+1)))); + Clear_Line := j + 1; + end loop; + Page(Clear_Line) := BS_40.Null_Bounded_Wide_String; + end if; + end loop; + end Compress; + + --- + + procedure Format (Page : in out Page_Type) is + Sm_Ada : BS_40.Bounded_Wide_String := + BS_40.To_Bounded_Wide_String("ada"); + Cap_Ada : constant Wide_String := "Ada"; + Char_Pos : Natural := 0; + Finished : Boolean := False; + Line : Natural := Page_Type'Last; + begin + + -- Add a period to the end of the last line. + while Line >= Page_Type'First and not Finished loop + if Page(Line) /= BS_40.Null_Bounded_Wide_String and + BS_40.Length(Page(Line)) <= BS_40.Max_Length + then + Page(Line) := BS_40.Append(Page(Line), '.'); + Finished := True; + end if; + Line := Line - 1; + end loop; + + -- Replace all occurrences of "ada" with "Ada". + for Line in Page_Type'First ..
