I have two different handlers, one which gets the names (which are numbers like "1.0" and "1.1") of folders within a folder, then converts that to an applescript list. Then it passes that list to another handler, which evaluates the list and supposedly identifies the highest number (I got it from http://www.macosxautomation.com/applescript/sbrt/sbrt-03.html ).
on set_values(project_path)
do shell script "ls " & project_path
get words of result
set allvalues to (result)
return allvalues
end set_values
Then I turn result into a variable for the next handler:
set values_list to result
And this is the handler the get the highest number from the list, courtesy of macosxautomation:
on highnum(values_list)
set the high_amount to ""
repeat with i from 1 to the count of the values_list
set this_item to item i of the values_list
set the item_class to the class of this_item
if the item_class is in {integer, real} then
if the high_amount is "" then
set the high_amount to this_item
else if this_item is greater than the high_amount then
set the high_amount to item i of the values_list
end if
else if the item_class is list then
set the high_value to highnum(this_item)
if the the high_value is greater than the high_amount then ¬
set the high_amount to the high_value
end if
end repeat
return high_amount
end highnum
The problem is that the second handler only ever gives off a null response, and i can't figure out why. Any help appreciated.
The point of the application is to simplify the creation of other applications, by allowing the creation of new 'projects', importing existing apps into a new 'project' and to allow editing of a 'project' with ease. In the event that you choose to edit a project, you can choose "minor update" (effectively adding a '0.0.1' to your latest version) or a number of other options i have already finished. The multi-decimal addition i can solve using text item delimiters, but I am not sure how to obtain a multi-decimal number from the highnum() handler, which is the critical part of the process
the highnum() handler compares real and integer values but the shell script returns string values.
AppleScript has a built-in option to compare numeric strings.
Edit: all values which contain at least one dot and do not contain any letter are considered.
on highnum(values_list)
set high_amount to "0.0"
considering numeric strings
repeat with aValue in values_list
set {TID, text item delimiters} to {text item delimiters, "."}
set aValueItems to text items of aValue
if (count aValueItems) > 1 then
set text item delimiters to ""
try
aValueItems as text as integer
if aValue > high_amount then set high_amount to contents of aValue
end try
end if
set text item delimiters to TID
end repeat
end considering
return high_amount
end highnum
this is a simpler version of the set_values() handler
on set_values(project_path)
return paragraphs of (do shell script "ls " & project_path)
end set_values
to add version strings you could use this handler, it considers strings with different "decimal places".
set newVersionString to addVersionStrings("1.1.1", "2.0") --> 3.1.1
on addVersionStrings(string1, string2)
set {TID, text item delimiters} to {text item delimiters, "."}
set textItems1 to text items of string1
set textItems2 to text items of string2
if (count textItems1) < (count textItems2) then
set minCount to count textItems1
set _sum to textItems2
set _add to textItems1
else
set minCount to count textItems2
set _sum to textItems1
set _add to textItems2
end if
repeat with i from 1 to minCount
set item i of _sum to (get (item i of _sum as integer) + (item i of _add as integer)) as text
end repeat
set theResult to _sum as text
set text item delimiters to TID
return theResult
end addVersionStrings
