Yet Another CGI question

by Apterigo (Scribe)
on Jun 15, 2000 at 00:03 UTC ( #18169=perlquestion: print w/replies, xml ) Need Help??

Apterigo has asked for the wisdom of the Perl Monks concerning the following question:

When I write CGI scripts, and try to run them from either windows or a unix shell, I get a message that says:

(offline mode: enter name=value pairs on standard input

I want to see the html that is going to be generated, is their a way I can do that?

    Well, if you don't want to enter any of the CGI name/value pairs just hit CONTROL-D. If you do want, enter the pairs, one on a line, then hit CONTROL-D.
      On Windows, it's Ctrl-Z. In both cases, enter it at the start of a line. That sends the program "end of file", ending the read, and you can all move on with your lives.
        And if the HTML is too long for you to look at on the screen, you can either pipe it into less (or favorite pager), or on a windows machine, redirect the output to a file.
        perl | less or perl > foo.htm
        With the second method, you can pull up a browser and check out what it looks like also.

    Or, change your 'use' statement to:
    use CGI qw/:standard -no_debug/;
    and you won't be prompted. This is useful if your script will be parsing/generating HTML but won't be invoked through the webserver.

    Or enter some dummy params as in
    $query = new CGI('dinosaur=barney&color=purple');

    cntl-D for unix variants, and I believe cntl-Z for Windows.

    It's not a bug, it's a feature:
    Just like passing variables via GET or POST, you have to give varibles like 'foo=bar'. Just hit Ctrl-D one or more times (depends on how many parameters it expects), then your script finishes.

    another way is just to pass some dummy params in on your command line:
    $ m=m
    satisfies the Perl interpreter, without worrying about pressing CTRL keys or anything like that. Handy if you are wanting to test inside a standard shell script or batch file.

    You can hit CTRL-D (or whatever the appopriate combination is for end-of-input on Windows) to simulate a query-string. You can also redirect data from a file or from echo to the program (through standard input).
