Description

GNU autogen is a program generating a text file from a template and a definition file. The template contains fixed text and variables those will be replaced under the control of the definition file.

By example from the following definition file 

AutoGen Definitions .;
list = { list_element = alpha;
         list_info    = "some alpha stuff"; };
list = { list_info    = "more beta stuff";
         list_element = beta; };
list = { list_element = omega;
         list_info    = "final omega stuff"; }

And the following template 

[+ AutoGen5 template +]
typedef enum {[+
   FOR list "," +]
        IDX_[+ (string-upcase! (get "list_element")) +][+
   ENDFOR list +] }  list_enum;

Autogen generates 

typedef enum {
        IDX_ALPHA,
        IDX_BETA,
        IDX_OMEGA }  list_enum;

The template file can be quite complex, you can read autogen documentation here.

The AnjutaAutogen object takes care of writing the definition file from a hash table and call autogen. The output can be written in a file or passed to a callback function. Autogen is executed asynchronously, so there is another callback function called when the processing is completed.

Read an autogen template file, optionally adding autogen markers.

To be recognized as an autogen template, the first line has to contain:

  • the start marker

  • "autogen5 template"

  • the end marker

These markers are a custom sequence of up to 7 characters delimiting the start and the end of autogen variables and macros.

This function can add this line using the value of start_marker and end_marker. If this line is already present in the file, start_marker and end_marker must be NULL.

this :

 A AnjutaAutogen object

filename :

 name of the input template file

start_marker :

 start marker string. [allow-none]

end_marker :

 end marker string. [allow-none]

Returns :

 TRUE if the file has been read without error.

anjuta_autogen_set_library_path ()

Add a new directory in the list of autogen libraries path.

Autogen can include files. These included file will be searched by default in the same directory than the template file. This functions allows you to add other directories.

this :

 A AnjutaAutogen object

directory :

 A path containing autogen library.

Define the name of the generated file.

this :

 A AnjutaAutogen object

filename :

 name of the generated file

Returns :

 TRUE if the file has been set without error.

anjuta_autogen_write_definition_file ()

gboolean            anjuta_autogen_write_definition_file
                                                        (AnjutaAutogen *this,

Write the autogen definition file. The definition file defined variables those will be used, typically replaced, in the template files.

The hash table keys are the names of the variables. The name can include an index in square bracket, by example "members[0]". All values are strings but but they could include children using braces, by example "{count=2; list="aa bb"}".

The file is created in a temporary directory and removed when the object is destroyed.

this :

 A AnjutaAutogen object

values :

 A hash table containing all definitions. [element-type utf8 utf8]

error :

 Error propagation and reporting

Returns :

 TRUE if the file has been written without error,

anjuta_check_autogen ()

gboolean            anjuta_check_autogen                (void);

Check if autogen version 5 is installed.

Returns :

 TRUE if autogen is installed.
