It provides an easy interface for parsing one -- or more files containing formatted data. The file can be viewed seen as -- a database where each record is a line and a field is a data element in -- this line. In this implementation an AWK record is a line. This means -- that a record cannot span multiple lines. The operating procedure is to -- read files line by line, with each line being presented to the user of -- the package. The interface provides services to access specific fields -- in the line. Thus it is possible to control actions taken on a line based -- on values of some fields. This can be achieved directly or by registering -- callbacks triggered on programmed conditions. -- -- The state of an AWK run is recorded in an object of type session. -- The following is the procedure for using a session to control an -- AWK run: -- -- 1) Specify which session is to be used. It is possible to use the -- default session or to create a new one by declaring an object of -- type Session_Type. For example: -- -- Computers : Session_Type; -- -- 2) Specify how to cut a line into fields. There are two modes: using -- character fields separators or column width. This is done by using -- Set_Fields_Separators or Set_Fields_Width. For example by: -- -- AWK.Set_Field_Separators (";,", Computers); -- -- or by using iterators' Separators parameter. -- -- 3) Specify which files to parse. This is done with Add_File/Add_Files -- services, or by using the iterators' Filename parameter. For -- example: -- -- AWK.Add_File ("myfile.db", Computers); -- -- 4) Run the AWK session using one of the provided iterators. -- -- Parse -- This is the most automated iterator. You can gain control on -- the session only by registering one or more callbacks (see -- Register). -- -- Get_Line/End_Of_Data -- This is a manual iterator to be used with a loop. You have -- complete control on the session. You can use callbacks but -- this is not required. -- -- For_Every_Line -- This provides a mixture of manual/automated iterator action. -- -- Examples of these three approaches appear below -- -- There are many ways to use this package. The following discussion shows -- three approaches to using this package, using the three iterator forms. -- All examples will use the following file (computer.db): -- -- Pluton;Windows-NT;Pentium III -- Mars;Linux;Pentium Pro -- Venus;Solaris;Sparc -- Saturn;OS/2;i486 -- Jupiter;MacOS;PPC -- -- 1) Using Parse iterator -- -- Here the first step is to register some action associated to a pattern -- and then to call the Parse iterator (this is the simplest way to use -- this unit). The default session is used here. For example to output the -- second field (the OS) of computer "Saturn". -- -- procedure Action is -- begin -- Put_Line (AWK.Field (2)); -- end Action; -- -- begin -- AWK.Register (1, "Saturn", Action'Access); -- AWK.Parse (";", "computer.db"); -- -- -- 2) Using the Get_Line/End_Of_Data iterator -- -- Here you have full control. For example to do the same as -- above but using a specific session, you could write: -- -- Computer_File : Session_Type; -- -- begin -- AWK.Set_Current (Computer_File); -- AWK.Open (Separators => ";", -- Filename => "computer.db"); -- -- -- Display Saturn OS -- -- while not AWK.End_Of_File loop -- AWK.Get_Line; -- -- if AWK.Field (1) = "Saturn" then -- Put_Line (AWK.Field (2)); -- end if; -- end loop; -- -- AWK.Close (Computer_File); -- -- -- 3) Using For_Every_Line iterator -- -- In this case you use a provided iterator and you pass the procedure -- that must be called for each record. You could code the previous -- example could be coded as follows (using the iterator quick interface -- but without using the current session): -- -- Computer_File : Session_Type; -- -- procedure Action (Quit : in out Boolean) is -- begin -- if AWK.Field (1, Computer_File) = "Saturn" then -- Put_Line (AWK.Field (2, Computer_File)); -- end if; -- end Action; -- -- procedure Look_For_Saturn is -- new AWK.For_Every_Line (Action); -- -- begin -- Look_For_Saturn (Separators => ";", -- Filename => "computer.db", -- Session => Computer_File); -- -- Integer_Text_IO.Put -- (Integer (AWK.NR (Session => Computer_File))); -- Put_Line (" line(s) have been processed."); -- -- You can also use a regular expression for the pattern. Let us output -- the computer name for all computer for which the OS has a character -- O in its name. -- -- Regexp : String := ".*O.*"; -- -- Matcher : Regpat.Pattern_Matcher := Regpat.Compile (Regexp); -- -- procedure Action is -- begin -- Text_IO.Put_Line (AWK.Field (2)); -- end Action; -- -- begin -- AWK.Register (2, Matcher, Action'Unrestricted_Access); -- AWK.Parse (";", "computer.db"); -- with Ada.Finalization; with GNAT.Regpat; package GNAT.AWK is Session_Error : exception; -- Raised when a Session is reused but is not closed File_Error : exception; -- Raised when there is a file problem (see below) End_Error : exception; -- Raised when an attempt is made to read beyond the end of the last -- file of a session.

Which means that ACTION -- will be executed if PATTERN match. A pattern in this implementation can -- be a simple string (match function is equality), a regular expression, -- a function returning a boolean. An action is associated to a pattern -- using the Register services. -- -- Each procedure Register will add a rule to the set of rules for the -- session. Rules are examined in the order they have been added. type Pattern_Callback is access function return Boolean; -- This is a pattern function pointer. When it returns True the associated -- action will be called. type Action_Callback is access procedure; -- A simple action pointer type Match_Action_Callback is access procedure (Matches : GNAT.Regpat.Match_Array); -- An advanced action pointer used with a regular expression pattern. It -- returns an array of all the matches. See GNAT.Regpat for further -- information. procedure Register (Field : Count; Pattern : String; Action : Action_Callback; Session : Session_Type); procedure Register (Field : Count; Pattern : String; Action : Action_Callback); -- Register an Action associated with a Pattern. The pattern here is a -- simple string that must match exactly the field number specified. procedure Register (Field : Count; Pattern : GNAT.Regpat.Pattern_Matcher; Action : Action_Callback; Session : Session_Type); procedure Register (Field : Count; Pattern : GNAT.Regpat.Pattern_Matcher; Action : Action_Callback); -- Register an Action associated with a Pattern. The pattern here is a -- simple regular expression which must match the field number specified. procedure Register (Field : Count; Pattern : GNAT.Regpat.Pattern_Matcher; Action : Match_Action_Callback; Session : Session_Type); procedure Register (Field : Count; Pattern : GNAT.Regpat.Pattern_Matcher; Action : Match_Action_Callback); -- Same as above but it pass the set of matches to the action -- procedure. This is useful to analyze further why and where a regular -- expression did match. procedure Register (Pattern : Pattern_Callback; Action : Action_Callback; Session : Session_Type); procedure Register (Pattern : Pattern_Callback; Action : Action_Callback); -- Register an Action associated with a Pattern. The pattern here is a -- function that must return a boolean. Action callback will be called if -- the pattern callback returns True and nothing will happen if it is -- False. This version is more general, the two other register services -- trigger an action based on the value of a single field only. procedure Register (Action : Action_Callback; Session : Session_Type); procedure Register (Action : Action_Callback); -- Register an Action that will be called for every line. This is -- equivalent to a Pattern_Callback function always returning True. -------------------- -- Parse iterator -- -------------------- procedure Parse (Separators : String := Use_Current; Filename : String := Use_Current; Session : Session_Type); procedure Parse (Separators : String := Use_Current; Filename : String := Use_Current); -- Launch the iterator, it will read every line in all specified -- session's files. Registered callbacks are then called if the associated -- pattern match. It is possible to specify a filename and a set of -- separators directly. This offer a quick way to parse a single -- file. These parameters will override those specified by Set_FS and -- Add_File. The Session will be opened and closed automatically. -- File_Error is raised if there is no file associated with Session, or if -- a file associated with Session is not longer readable. It raises -- Session_Error is Session is already open. ----------------------------------- -- Get_Line/End_Of_Data Iterator -- ----------------------------------- type Callback_Mode is (None, Only, Pass_Through); -- These mode are used for Get_Line/End_Of_Data and For_Every_Line -- iterators. The associated semantic is: -- -- None -- callbacks are not active. This is the default mode for -- Get_Line/End_Of_Data and For_Every_Line iterators. -- -- Only -- callbacks are active, if at least one pattern match, the associated -- action is called and this line will not be passed to the user. In -- the Get_Line case the next line will be read (if there is some -- line remaining), in the For_Every_Line case Action will -- not be called for this line. -- -- Pass_Through -- callbacks are active, for patterns which match the associated -- action is called. Then the line is passed to the user. It means -- that Action procedure is called in the For_Every_Line case and -- that Get_Line returns with the current line active. -- procedure Open (Separators : String := Use_Current; Filename : String := Use_Current; Session : Session_Type); procedure Open (Separators : String := Use_Current; Filename : String := Use_Current); -- Open the first file and initialize the unit.

Next call to Get_Line will return the following -- line in the file. By default the registered callbacks are not called by -- Get_Line, this can activated by setting Callbacks (see Callback_Mode -- description above). File_Error may be raised if a file associated with -- Session is not readable. -- -- When Callbacks is not None, it is possible to exhaust all the lines -- of all the files associated with Session. In this case, File_Error -- is not raised. -- -- This procedure can be used from a subprogram called by procedure Parse -- or by an instantiation of For_Every_Line (see below). function End_Of_Data (Session : Session_Type) return Boolean; function End_Of_Data return Boolean; pragma Inline (End_Of_Data); -- Returns True if there is no more data to be processed in Session. It -- means that the latest session's file is being processed and that -- there is no more data to be read in this file (End_Of_File is True). function End_Of_File (Session : Session_Type) return Boolean; function End_Of_File return Boolean; pragma Inline (End_Of_File); -- Returns True when there is no more data to be processed on the current -- session's file. procedure Close (Session : Session_Type); -- Release all associated data with Session. All memory allocated will -- be freed, the current file will be closed if needed, the callbacks -- will be unregistered. Close is convenient in reestablishing a session -- for new use. Get_Line is no longer usable (will raise File_Error) -- except after a successful call to Open, Parse or an instantiation -- of For_Every_Line. ----------------------------- -- For_Every_Line iterator -- ----------------------------- generic with procedure Action (Quit : in out Boolean); procedure For_Every_Line (Separators : String := Use_Current; Filename : String := Use_Current; Callbacks : Callback_Mode := None; Session : Session_Type); generic with procedure Action (Quit : in out Boolean); procedure For_Every_Line_Current_Session (Separators : String := Use_Current; Filename : String := Use_Current; Callbacks : Callback_Mode := None); -- This is another iterator.

Please read this before -- making any "simplifications". -- Correct implementation of this package is more difficult than one might -- expect. After considering (and coding) several alternatives, we settled on -- the present compromise. Things we do not like about this implementation -- include: -- - It is vulnerable to bad Task_Id values, to the extent of possibly -- trashing memory and crashing the runtime system. -- - It requires dynamic storage allocation for each new attribute value, -- except for types that happen to be the same size as System.Address, or -- shorter. -- - Instantiations at other than the library level rely on being able to -- do down-level calls to a procedure declared in the generic package body. -- This makes it potentially vulnerable to compiler changes. -- The main implementation issue here is that the connection from task to -- attribute is a potential source of dangling references. -- When a task goes away, we want to be able to recover all the storage -- associated with its attributes. The Ada mechanism for this is finalization, -- via controlled attribute types. For this reason, the ARM requires -- finalization of attribute values when the associated task terminates. -- This finalization must be triggered by the tasking runtime system, during -- termination of the task. Given the active set of instantiations of -- Ada.Task_Attributes is dynamic, the number and types of attributes -- belonging to a task will not be known until the task actually terminates. -- Some of these types may be controlled and some may not. The RTS must find -- some way to determine which of these attributes need finalization, and -- invoke the appropriate finalization on them. -- One way this might be done is to create a special finalization chain for -- each task, similar to the finalization chain that is used for controlled -- objects within the task. This would differ from the usual finalization -- chain in that it would not have a LIFO structure, since attributes may be -- added to a task at any time during its lifetime. This might be the right -- way to go for the longer term, but at present this approach is not open, -- since GNAT does not provide such special finalization support. -- Lacking special compiler support, the RTS is limited to the normal ways an -- application invokes finalization, i.e. -- a) Explicit call to the procedure Finalize, if we know the type has this -- operation defined on it. This is not sufficient, since we have no way -- of determining whether a given generic formal Attribute type is -- controlled, and no visibility of the associated Finalize procedure, in -- the generic body. -- b) Leaving the scope of a local object of a controlled type. This does not -- help, since the lifetime of an instantiation of Ada.Task_Attributes -- does not correspond to the lifetimes of the various tasks which may -- have that attribute. -- c) Assignment of another value to the object. This would not help, since -- we then have to finalize the new value of the object. -- d) Unchecked deallocation of an object of a controlled type. This seems to -- be the only mechanism available to the runtime system for finalization -- of task attributes. -- We considered two ways of using unchecked deallocation, both based on a -- linked list of that would hang from the task control block. -- In the first approach the objects on the attribute list are all derived -- from one controlled type, say T, and are linked using an access type to -- T'Class. The runtime system has an Unchecked_Deallocation for T'Class with -- access type T'Class, and uses this to deallocate and finalize all the -- items in the list. The limitation of this approach is that each -- instantiation of the package Ada.Task_Attributes derives a new record -- extension of T, and since T is controlled (RM 3.9.1 (3)), instantiation is -- only allowed at the library level. -- In the second approach the objects on the attribute list are of unrelated -- but structurally similar types. Unchecked conversion is used to circument -- Ada type checking. Each attribute-storage node contains not only the -- attribute value and a link for chaining, but also a pointer to descriptor -- for the corresponding instantiation of Task_Attributes. The instantiation -- descriptor contains pointer to a procedure that can do the correct -- deallocation and finalization for that type of attribute. On task -- termination, the runtime system uses the pointer to call the appropriate -- deallocator. -- While this gets around the limitation that instantations be at the library -- level, it relies on an implementation feature that may not always be safe, -- i.e. that it is safe to call the Deallocate procedure for an instantiation -- of Ada.Task_Attributes that no longer exists. In general, it seems this -- might result in dangling references. -- Another problem with instantiations deeper than the library level is that -- there is risk of storage leakage, or dangling references to reused -- storage. That is, if an instantiation of Ada.Task_Attributes is made -- within a procedure, what happens to the storage allocated for attributes, -- when the procedure call returns? Apparently (RM 7.6.1 (4)) any such -- objects must be finalized, since they will no longer be accessible, and in -- general one would expect that the storage they occupy would be recovered -- for later reuse. (If not, we would have a case of storage leakage.) -- Assuming the storage is recovered and later reused, we have potentially -- dangerous dangling references. When the procedure containing the -- instantiation of Ada.Task_Attributes returns, there may still be -- unterminated tasks with associated attribute values for that instantiation. -- When such tasks eventually terminate, the RTS will attempt to call the -- Deallocate procedure on them. If the corresponding storage has already -- been deallocated, when the master of the access type was left, we have a -- potential disaster. This disaster is compounded since the pointer to -- Deallocate is probably through a "trampoline" which will also have been -- destroyed. -- For this reason, we arrange to remove all dangling references before -- leaving the scope of an instantiation. This is ugly, since it requires -- traversing the list of all tasks, but it is no more ugly than a similar -- traversal that we must do at the point of instantiation in order to -- initialize the attributes of all tasks. At least we only need to do these -- traversals if the type is controlled. -- We chose to defer allocation of storage for attributes until the Reference -- function is called or the attribute is first set to a value different from -- the default initial one. This allows a potential savings in allocation, -- for attributes that are not used by all tasks. -- For efficiency, we reserve space in the TCB for a fixed number of -- direct-access attributes. These are required to be of a size that fits in -- the space of an object of type System.Address. Because we must use -- unchecked bitwise copy operations on these values, they cannot be of a -- controlled type, but that is covered automatically since controlled -- objects are too large to fit in the spaces. -- We originally deferred the initialization of these direct-access -- attributes, just as we do for the indirect-access attributes, and used a -- per-task bit vector to keep track of which attributes were currently -- defined for that task. We found that the overhead of maintaining this -- bit-vector seriously slowed down access to the attributes, and made the -- fetch operation non-atomic, so that even to read an attribute value -- required locking the TCB. Therefore, we now initialize such attributes for -- all existing tasks at the time of the attribute instantiation, and -- initialize existing attributes for each new task at the time it is -- created. -- The latter initialization requires a list of all the instantiation -- descriptors. Updates to this list, as well as the bit-vector that is used -- to reserve slots for attributes in the TCB, require mutual exclusion. That -- is provided by the Lock/Unlock_RTS. -- One special problem that added complexity to the design is that the -- per-task list of indirect attributes contains objects of different types. -- We use unchecked pointer conversion to link these nodes together and -- access them, but the records may not have identical internal structure. -- Initially, we thought it would be enough to allocate all the common -- components of the records at the front of each record, so that their -- positions would correspond. Unfortunately, GNAT adds "dope" information at -- the front of a record, if the record contains any controlled-type -- components. -- -- This means that the offset of the fields we use to link the nodes is at -- different positions on nodes of different types. To get around this, each -- attribute storage record consists of a core node and wrapper. The core -- nodes are all of the same type, and it is these that are linked together -- and generally "seen" by the RTS. Each core node contains a pointer to its -- own wrapper, which is a record that contains the core node along with an -- attribute value, approximately as follows: -- type Node; -- type Node_Access is access all Node; -- type Node_Access; -- type Access_Wrapper is access all Wrapper; -- type Node is record -- Next : Node_Access; -- ... -- Wrapper : Access_Wrapper; -- end record; -- type Wrapper is record -- Dummy_Node : aliased Node; -- Value : aliased Attribute; -- the generic formal type -- end record; -- Another interesting problem is with the initialization of the -- instantiation descriptors. Originally, we did this all via the Initialize -- procedure of the descriptor type and code in the package body. It turned -- out that the Initialize procedure needed quite a bit of information, -- including the size of the attribute type, the initial value of the -- attribute (if it fits in the TCB), and a pointer to the deallocator -- procedure. These needed to be "passed" in via access discriminants.
