Modules are generally used either as function libraries (which.plfiles are still but less commonly used for), or as object libraries where a module is used to define a class and its methods. Its last statement
and Perl does not distinguish between a function and a method stored in a package. The same builtin,sub, declares both. Perl will happily dispatch to a function called as a method. Likewise, you can invoke a method as if it were a function—fully-qualified, exported, or as a reference...
Perl_yylex() is a function inside toke.c, at line 2190. What's weird is that I can't match the opening { (I'm using vi, "%" matches braces and parens, but not that one.)I'll take a look at the Configure output and see if anything helps. 0 Kudos Reply H.Merijn Brand (...
Modules are generally used either as function libraries (which.plfiles are still but less commonly used for), or as object libraries where a module is used to define a class and its methods. Its last statement returns true. The naming convention requires it to have a.pmextension. Example: ...
An observer is a function. See "notify_observers" for its calling convention. This function is used internally by Workflow::Factory to implement observability as documented in the section "WORKFLOWS ARE OBSERVABLE" notify_observers( @arguments ) Calls all observer functions registered through add_...
The open function can also accept pathnames that are Universal Naming Convention (UNC) pathnames under Microsoft Windows. UNC pathnames are formatted like this: \\machinename\sharename Perl accepts UNC pathnames with either backslashes or forward slashes and opens files on remote systems if your ...
If an argument were actually literal and you tried to change it, you'd take a (presumably fatal) exception. For example, this won't work: upcase_in("frederick"); It would be much safer if the "upcase_in()" function were written to return a copy of its parameters instead of ...
It is strongly recommended that you use this flag when you run Configure. If you do not do this, but later answer the question about large files when Configure asks you, you may get a configuration that cannot be compiled, or that does not function as expected. ...

These override the default and the options given to the compiling function. For example, on a Unix system where LF is the default newline sequence, the pattern (*CR)a.b changes the convention to CR. That pattern matches "a\nb" because LF is no longer a newline. If more than one of...
