How do I expand function calls in a string?

Current Perl documentation can be found at perldoc.perl.org.

Here is our local, out-dated (pre-5.6) version:

This is documented in the perlref manpage. In general, this is fraught with quoting and readability problems, but it is possible. To interpolate a subroutine call (in list context) into a string:

    print "My sub returned @{[mysub(1,2,3)]} that time.\n";

If you prefer scalar context, similar chicanery is also useful for arbitrary expressions:

    print "That yields ${\($n + 5)} widgets\n";

Version 5.004 of Perl had a bug that gave list context to the expression in ${...}, but this is fixed in version 5.005.

See also ``How can I expand variables in text strings?'' in this section of the FAQ.

[choroba]: How is Bembel different from Krug?
[hippo]: karlgoethebier, Ich habe kein Deutsch.
[Corion]: choroba: A Bembel is a traditional pottery ware, which is only(!) used for serving Cider (well, Apfelwein)
[shmem]: choroba: it's hessisch
[Corion]: Not every Krug is a Bembel!
[karlgoethebier]: there is just the mug: 🍺
[Corion]: A Bembel must look like this
[karlgoethebier]: https://de. wikipedia.org/ wiki/Bembel#/ media/File: Bembel_Zum_blauen_ Bock_1978.jpg
[choroba]: as my friend says, Ich stehe Deutsche ver nicht aber klein ;-)
[Corion]: Krug is generic pottery ware for pouring beverages, but a Bembel is painted with that blue paint and contains only (!) Apfelwein
