"CGI::Formalware" - Convert an XML file into a suite of CGI forms.

In your browser, type: localhost/cgi-bin/x.pl

where x.pl contains nothing more than:

        #!perl -w
        use strict;
        use lib 'C:/Perl';
        use lib 'C:/Perl/Scripts/General';      # Ie $PERL5LIB.
        use CGI::Formalware;
        my($form) = CGI::Formalware -> new({form2file => 1, debug => 1});
        $form -> process();
        exit(0);

Upon starting, "CGI::Formalware" asks for the name of your XML file, which is assumed to be in cgi-bin/.

To provide a type of repository for frequently used scripts, which can then be executed locally or remotely (via Net::Telnet), by just entering a password (for remote scripts), and clicking.

You install "CGI::Formalware", as you would install any perl module library, by running these commands:

        perl Makefile.PL
        make
        make test
        make install

If you want to install a private copy of "CGI::Formalware" in your home directory, then you should try to produce the initial Makefile with something like this command:

        perl Makefile.PL LIB=~/perl
                or
        perl Makefile.PL LIB=C:/Perl/Site/Lib

If, like me, you don't have permission to write man pages into unix system directories, use:

        make pure_install

instead of make install. This option is secreted in the middle of p 414 of the second edition of the dromedary book.

Webmasters.

None. Even worse, "CGI::Formalware" is designed to circumvent a web server's concept of what Apache calls DocumentRoot.

new takes either no parameters, or an anonymous hash. See the example above. Keys and values recognized are:

  • debug => 1 means turn on debugging. At the moment this opens and closes the file CGI-Formalware.log, but does not write anything to it
  • form2file => 1 means output each form to a file, using the name given by the form's formFileName attribute. The forms are written to cgi-bin/. If the form has no such attribute, this option is ignored. See example below
  • timeScripts => 1 means report elapsed time at the end of each script's output

  • Read an XML file, whose format is fixed, and generate a suite of CGI forms
  • A cascading style sheet can be specified for each form individually
  • A Table of Contents may appear on each form
  • Each form is more-or-less assumed to contain a list of scripts
  • Tokens in the XML correspond to a few functions available in Lincoln Stein's CGI.pm. Available tokens are:
  • fileField

            <fileField
                    name            = 'fileName'
                    prompt          = 'Filename: '
                    size            = '60'
                    override        = '0'
            />
        
  • horizontalRule

            <horizontalRule />
        
  • paragraph

            <paragraph />
            <paragraph text = 'Output a comment' />
        
  • radioGroup

            <radioGroup
                    name            = 'serverName'
                    prompt          = 'Server name: '
                    value           = 'Example|Simple|Test'
                    columns         = '1'   # Optional. Defaults to '1'. Use a string, not a digit
            />
        
  • textField

            <textField
                    name            = 'username'
                    prompt          = 'Username: '
                    value           = ''
                    size            = '15'
                    override        = '0'
            />
        

Over time, more functions will be added.

  • A textField with the name 'password' is treated as a password field. Also, the entity 'script' defines a Unix- or DOS-type batch file
  • These entities produce on-screen fields, or, in the case of the scripts, a vertical array of radio buttons
  • So, to run a script you fill in whatever fields the script uses and then select that script
  • Macros in the scripts, eg %fileName% are expanded with the current value of the field whose name appears between the % signs
  • A script whose last line is 'ftp -n -v' is recognized and handled specially. Your form must contain textFields called 'host', 'username' and 'password' and 'fileName'. A binary 'get' is performed. This will be made more flexible one day
  • Scripts have an attribute 'type', which can be 'local' or 'remote'.

    Remote scripts are passed to Net::Telnet, on the assumption that you know what you are doing. Your form must contain textFields called 'host', 'username' and 'password'

Forms are linked with 'Previous form', 'Next form' buttons.

Any previously-entered textFields, except those whose name is 'password', are remembered when you return to a form. This is very convenient.

The password values are zapped by CGI.pm, not by me. This is a security feature. It means you can walk away from your system and not have someone gain automatic access to a remote system.

Each form entity may have a 'css' attribute, giving the name of the CSS file for that form. These attribute values are like '/CGI-Formalware.css', which, under Apache, means this value is prefixed with DocumentRoot. That is, the path to the CSS is a URI, and will not be seen if in cgi-bin/.

The compulsory elements are: H1, H2 and P.TOC.

Herewith a sample:

        H1
        {
                font-size:                      20pt;
                alignment:                      center;
                color:                          teal;
        }
        H2
        {
                font-size:                      16pt;
                font-style:                     italic;
                color:                          maroon;
        }
        P.TOC
        {
                font-size:                      12pt;
                color:                          white;
                background-color:       blue;
        }

None.

These checks are performed:

  • Each forms entity may have a 'tocEntry' attribute. If present, and if the tocVisible attribute is 'true', then a Table of Contents is put on each form, headed by this text. The default is 'Contents'
  • Each forms entity may have a 'tocVisible' attribute. If its value is 'True', then a Table of Contents is put on each form, headed by the value of 'tocEntry'. The default is 'True'
  • Each form entity must have 'heading' and 'tocEntry' attributes
  • Each form entity must have a unique 'heading' attribute
  • Each form entity may have a unique 'formFileName' attribute. If present, then this file name is used to output the form to a file if the constructor option new({form2file => 1}) is used
  • Each fileField entity must have 'name', 'prompt', 'value' and 'size' attributes
  • Each textField entity must have 'name', 'prompt', 'value' and 'size' attributes
  • Each scripts entity must have a 'heading' attribute
  • Each script entity must have 'heading', 'type' and 'line' attributes
  • Each script entity must have a unique 'heading' attribute
  • Each script entity's 'type' attribute must be 'local' or 'remote'

TBA.

Nope, I don't recognize them. Maybe one day...
