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

Dear Mongers!

Need your help with Cyrillic names. Here is the simple code:

#!/usr/bin/perl -w use strict; use warnings; use locale; use Cyrillic; chomp (my $interest = <STDIN>); print_dir ($interest); sub print_dir { chdir shift; foreach (glob "./*"){ print $_ ,"\n"; }; }
then I type *C:/Users/Артём/* , ofc without "*" and it prints only the files of ./ directory - chdir fails! How can I fix this? My Username is in Cyrillic symbols and I want Perl to understand it...

Replies are listed 'Best First'.

    G'day Artimus,

    The first thing I recommend you do is read the chdir documentation and understand how it behaves in the event of failure. Then hand-craft code to give you a customised message (when it fails) or let the autodie pragma do it for you (which is a lot less work and my preference).

    I created a directory called Артём and added a few empty files for testing:

    $ ls -l Артём
    total 0
    -rw-r--r--  1 ken  staff  0 13 Mar 12:20 test1
    -rw-r--r--  1 ken  staff  0 13 Mar 12:20 test2
    -rw-r--r--  1 ken  staff  0 13 Mar 12:21 test3
    

    Then I ran this example code twice: first with a non-existent directory and then with Артём:

    #!/usr/bin/env perl use strict; use warnings; use autodie; print 'DIR? '; chomp(my $dir = <STDIN>); chdir $dir; print "$_\n" for glob './*';

    Sample runs:

    DIR? not_a_dir Can't chdir('not_a_dir'): No such file or directory at ...
    DIR? Артём
    ./test1
    ./test2
    ./test3
    

    I suggest you try this and see what output you get.

    Assuming the issue isn't that you've just mistyped the directory name, it might be related to the drive letter (C:) in the directory name. I don't have access to Perl on any MSWin systems so I can't test that for you but many others here can: report your results and, if it's a portability issue, I'm sure someone can help you.

    [I used <pre>...</pre> (or <tt>...</tt>) tags where necesary to display the Cyrillic; <code>...</code> (or <c>...</c>) tags display numeric character entity references. You may need to do the same when reporting your results.]

    Did you tell Perl what encoding your STDIN uses?

      erm, could you write required code modifications please?

    Artemis:

    Try chomping your directory name before passing it to print_dir. It worked for me after doing so.

    When your only tool is a hammer, all problems look like your thumb.

      Am I not doing so?

        Artimus:

        Sorry, I missed that. Try checking for errors from chdir to determine when and why it fails.

        I just read the documentation for the Cyrillic module: It seems that it's not intended to help you translate the user input strings to unicode. It appears to be a way for you to use Cyrillic in your scripts. However, I've not finished my coffee this morning, and I find the documentation a bit difficult to read.
