( [id://3333]=superdoc: print w/replies, xml ) Need Help??
No, that won't work. The use inside the eval BLOCK is compiled at compile time, but the string in eval EXPR is not. eval "use Foo"; is nothing but an obfuscated way to say require Foo; Foo->import;

Neither case is a job for eval here. If you want variable paths at compile time, you do the following:

my $libpath; BEGIN { $libpath = "/foo/bar"; } use lib $libpath;
If you want to load modules with dynamic @INC at runtime, you make use of the aforemention construct:
{ local @INC = ("/foo/bar", @INC); require Foo; Foo->import; }
eval will not help. And $a is a really awful name for a variable (plus $a and $b are reserved for sort). :)

Makeshifts last the longest.


In reply to Re^4: modify @INC by Aristotle
in thread modify @INC by pfm

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.
