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

  • 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).
