NAME

       templates2ada - generate Ada sources from a templates file

SYNOPSIS

       templates2ada [options]

DESCRIPTION

       templates2ada  parses  all  the	template  files  in  a directory and then generates an output file from these, based on a template file (a
       default example of which is provided as /usr/share/doc/libtemplates-parser-dev/examples/templates.tads). The latter contains  in  fact  two
       examples,  depending on whether one Ada package should be generated per template, or whether a single package should be built.  In the for-
       mer case, if you are using the GNAT compiler, you should run `gnatchop' on the resulting file. Here is an example:

	    $ rm -f src/templates/*.ads
	    $ templates2ada -d resources/ -o src/templates/generated -r
	    $ cd src/templates; gnatchop -w -q generated
	    $ rm -f src/templates/generated

       One of the goals of templates2ada is to ensure that you are only setting tags that actually exist in the template  (and	thus  prevent,	as
       much as possibly, typos in the name of tags); also, when combined with other tools, to help ensure that all tags needed by the template are
       properly set.

       templates2ada also has special knowledge about HTTP constructs and will generate Ada constants for the HTTP parameters you might receive in
       return. Once more the goal is to help avoid typos in the Ada code.

       For instance, we will consider a simple template file, found in a local file `resources/block1.thtml'. This template contains the following
       simple html code:

	    <form>
	      <input name="PARAM1" value="@_TAG1_@" />
	      <input name="PARAM2" value="@_TAG2_@" />
	    </form>

       When you run templates2ada, the following Ada package will be generated. Note that this is only the default output of templates2ada,  which
       can be fully tailored to your needs.

	    package Templates.Block1 is
	      pragma Style_Checks (Off);
	      Template : constant string := "resources/block1.thtml";
	      Tag1 : constant String := "TAG1";
	      Tag2 : constant String := "TAG2";
	      package Http is
		Param1 : constant String := "PARAM1";
		Param2 : constant String := "PARAM2";
	      end Http;
	    end Templates.Block1;

OPTIONS

       -d dir Search for template files in dir.

       -h     Display a summary of options.

       -o file
	      Write the output to file.

       -e ext Process all files with extension ext that are in the input directory; consider these files as template files.

       -r     Recurse into subdirectories.

       -t file
	      Use  file  as  the  output  template  file.  The	templates  parser comes with an example for such a file, /usr/share/doc/templates-
	      parser/examples/templates.tads, that you can adapt to your own needs.

       -v     Verbose mode.  This will output a warning when an http parameter has a name made only of template parser	tags,  since  no  matching
	      entry can then be created for it in the output file.
