Fell into Perl when doing sysadmin work on a bunch of SPARCstations in 1994. Since then have used it for a mix of web development and data-munging. For the past several years (since 2013) I've had the good fortune of working in Perl shops. I hope it lasts. I blog about Perl and other things at https://phoenixtrap.com

    No real Perl code here, but I thought it would be neat to try to port the map() and grep() functions to AppleScript and see if that much-maligned language could use a little higher-order programming love.

    I've also posted a thread on MacScripter, but here's the code in question. Thoughts?

    on map over theList given script:theScript set resultList to {} repeat with theItem in theList set resultList to resultList & theScript's lambda(theItem) end repeat return resultList end map on grep over theList given script:theScript set resultList to {} repeat with theItem in theList tell theScript if lambda(theItem) is true then set resultList to resultList & theItem end if end tell end repeat return resultList end grep -- end library script mapScript property HowMany : 0 on lambda(someone) set HowMany to HowMany + 1 return someone & " Gardner " & HowMany end lambda end script map over {"Mark", "Erin", "David"} given script:mapScript script grepScript on lambda(someone) considering case if contents of someone is equal to "David" then return true end if return false end considering end lambda end script grep over {"Mark", "Erin", "David"} given script:grepScript

    Blame my co-worker Jim.
    #!/usr/bin/perl my %bologna = ( firstname => 'OSCAR', secondname => 'MAYER', ); chomp foreach @days; read STDIN, $me, 3; print "Because ", values %bologna, " has a way with BOLOGNA\n" if $me eq 'why';

I'm finding myself using this idiom a lot for a current project. Adjust to taste for your own applications.

I'm working on a behemoth of a script to inventory Windows Oracle servers, using Win32::OLE and Microsoft's WMI to pick up various interesting facts. This is probably of interest to only a few people (if that's you, I feel your pain), but I ended up writing two snippets that do the same thing, and I thought it would make a good example of traditional procedural code vs. utter and total abuse of the map function.

A short example of WMI and Win32::OLE to get info from another server. Note that the hostname needs to be laundered or Win32::OLE will cry.
