( [id://3333]=superdoc: print w/replies, xml ) Need Help??

I recently answered this question on the beginners-perl mailing list. I think you might find the reponse very helpful.


use Term::ReadKey; ReadMode('noecho'); $password = ReadLine(0);

I've never used that before but some may be curious how I found it. Here's the trick:

    perldoc perltoc > perltoc.txt

That sends the perltoc (Perl Table of Contents) to a text file. I sometimes scan through this file to pick up new tricks. When I see something that interests me (such as "password"), I scan through the relevant entries. In this case, I saw the following entries:

    [snip]
    How do I clear the screen?
    How do I get the screen size?
    How do I ask the user for a password?
    How do I read and write the serial port?
    [snip]

The one about asking a user for a password looked useful, so I typed in:

    perldoc -q "How do I ask the user for a password?"

That actually gave a lot more information than what I sent you, so you should give it a try :)

The '-q' options stands for "FAQ keyword", but it can just as easily stand for 'question'.

Cheers,

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
