       templates2ada - generate Ada sources from a templates file


       templates2ada [options]


       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 former 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:

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

       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;


       -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.
