A directory --- can be treated as a file, using open and close routines, and a scanning --- routine is provided for iterating through the entries in a directory. - --- See also child package GNAT.Directory_Operations.Iteration - -with Ada.Strings.Maps; - -package GNAT.Directory_Operations is - - subtype Dir_Name_Str is String; - -- A subtype used in this package to represent string values that are - -- directory names. A directory name is a prefix for files that appear - -- with in the directory. This means that for UNIX systems, the string - -- includes a final '/', and for DOS-like systems, it includes a final - -- '\' character. It can also include drive letters if the operating - -- system provides for this. The final '/' or '\' in a Dir_Name_Str is - -- optional when passed as a procedure or function in parameter. - - type Dir_Type is limited private; - -- A value used to reference a directory. Conceptually this value includes - -- the identity of the directory, and a sequential position within it. - - Null_Dir : constant Dir_Type; - -- Represent the value for an uninitialized or closed directory - - Directory_Error : exception; - -- Exception raised if the directory cannot be opened, read, closed, - -- created or if it is not possible to change the current execution - -- environment directory. - - Dir_Separator : constant Character; - -- Running system default directory separator - - -------------------------------- - -- Basic Directory operations -- - -------------------------------- - - procedure Change_Dir (Dir_Name : Dir_Name_Str); - -- Changes the working directory of the current execution environment - -- to the directory named by Dir_Name. Raises Directory_Error if Dir_Name - -- does not exist. - - procedure Make_Dir (Dir_Name : Dir_Name_Str); - -- Create a new directory named Dir_Name. Raises Directory_Error if - -- Dir_Name cannot be created. - - procedure Remove_Dir (Dir_Name : Dir_Name_Str); - -- Remove the directory named Dir_Name. Raises Directory_Error if Dir_Name - -- cannot be removed. - - function Get_Current_Dir return Dir_Name_Str; - -- Returns the current working directory for the execution environment. - - procedure Get_Current_Dir (Dir : out Dir_Name_Str; Last : out Natural); - -- Returns the current working directory for the execution environment - -- The name is returned in Dir_Name. Last is the index in Dir_Name such - -- that Dir_Name (Last) is the last character written. If Dir_Name is - -- too small for the directory name, the name will be truncated before - -- being copied to Dir_Name. - - ------------------------- - -- Pathname Operations -- - ------------------------- - - subtype Path_Name is String; - -- All routines using Path_Name handle both styles (UNIX and DOS) of - -- directory separators (either slash or back slash). - - function Dir_Name (Path : Path_Name) return Dir_Name_Str; - -- Returns directory name for Path. This is similar to the UNIX dirname - -- command. Everything after the last directory separator is removed. If - -- there is no directory separator the current working directory is - -- returned. - - function Base_Name - (Path : Path_Name; - Suffix : String := "") - return String; - -- Any directory prefix is removed. If Suffix is non-empty and is a - -- suffix of Path, it is removed. This is equivalent to the UNIX basename - -- command. The following rule is always true: - -- - -- 'Path' and 'Dir_Name (Path) & Directory_Separator & Base_Name (Path)' - -- represent the same file. - -- - -- This function is not case-sensitive on systems that have a non - -- case-sensitive file system like Windows, OS/2 and VMS. - - function File_Extension (Path : Path_Name) return String; - -- Return the file extension. This is the string after the last dot - -- character in File_Name (Path). It returns the empty string if no - -- extension is found. The returned value does contains the file - -- extension separator (dot character). - - function File_Name (Path : Path_Name) return String; - -- Returns the file name and the file extension if present. It removes all - -- path information. This is equivalent to Base_Name with default Extension - -- value. - - type Path_Style is (UNIX, DOS, System_Default); - - function Normalize_Pathname - (Path : Path_Name; - Style : Path_Style := System_Default) - return Path_Name; - -- Removes all double directory separator and converts all '\' to '/' if - -- Style is UNIX and converts all '/' to '\' if Style is set to DOS. This - -- function will help to provide a consistent naming scheme running for - -- different environments. If style is set to System_Default the routine - -- will use the default directory separator on the running environment. - - function Expand_Path (Path : Path_Name) return Path_Name; - -- Returns Path with environment variables (string preceded by a dollar - -- sign) replaced by the current environment variable value. For example, - -- $HOME/mydir will be replaced by /home/joe/mydir if $HOME environment - -- variable is set to /home/joe. The variable can be surrounded by the - -- characters '{' and '}' (curly bracket) if needed as in ${HOME}/mydir. - -- If an environment variable does not exists the variable will be replaced - -- by the empty string. Two dollar signs are replaced by a single dollar - -- sign. Note that a variable must start with a letter. If there is no - -- closing curly bracket for an opening one there is no translation done, - -- so for example ${VAR/toto is returned as ${VAR/toto. - - --------------- - -- Iterators -- - --------------- - - procedure Open (Dir : out Dir_Type; Dir_Name : Dir_Name_Str); - -- Opens the directory named by Dir_Name and returns a Dir_Type value - -- that refers to this directory, and is positioned at the first entry. - -- Raises Directory_Error if Dir_Name cannot be accessed. In that case - -- Dir will be set to Null_Dir. - - procedure Close (Dir : in out Dir_Type); - -- Closes the directory stream refered to by Dir. After calling Close - -- Is_Open will return False. Dir will be set to Null_Dir. - -- Raises Directory_Error if Dir has not be opened (Dir = Null_Dir). - - function Is_Open (Dir : Dir_Type) return Boolean; - -- Returns True if Dir is open, or False otherwise. - - procedure Read - (Dir : in out Dir_Type; - Str : out String; - Last : out Natural); - -- Reads the next entry from the directory and sets Str to the name - -- of that entry. Last is the index in Str such that Str (Last) is the - -- last character written. Last is 0 when there are no more files in the - -- directory. If Str is too small for the file name, the file name will - -- be truncated before being copied to Str. The list of files returned - -- includes directories in systems providing a hierarchical directory - -- structure, including . (the current directory) and .. (the parent - -- directory) in systems providing these entries. The directory is - -- returned in target-OS form. Raises Directory_Error if Dir has not - -- be opened (Dir = Null_Dir). - - function Read_Is_Thread_Safe return Boolean; - -- Indicates if procedure Read is thread safe. On systems where the - -- target system supports this functionality, Read is thread safe, - -- and this function returns True (e.g. this will be the case on any - -- UNIX or UNIX-like system providing a correct implementation of the - -- function readdir_r). If the system cannot provide a thread safe - -- implementation of Read, then this function returns False. - -private - - type Dir_Type_Value; - type Dir_Type is access Dir_Type_Value; - - Null_Dir : constant Dir_Type := null; - - pragma Import (C, Dir_Separator, "__gnat_dir_separator"); - - Dir_Seps : constant Ada.Strings.Maps.Character_Set := - Ada.Strings.Maps.To_Set ("/\"); - -- UNIX and DOS style directory separators. - -end GNAT.Directory_Operations;
