Create getter / setter snippet

Script Debugger
#1

Hi,

I’d like to create a getter / setter from a variable with a snippet.

Is it possible ?

Thx.

#2

Can you give us an example of what you are trying to accomplish?

A snippet can certainly generate a pair of handlers (eg. getter and setter), and linked-tags allow an edit in one tag (eg. related names) can be applied to other parts of the snippet.

#3

For example, create a property myProperty : « myValue », select it and invoke a snippet to create a method to get this property like on getMyProperty() return myProperty.

Thx.

#4

Is there some reason you need accessor methods for a property?

#5

Well, for example I have a String lib which contains a uc special chars string (like a constant) :
property ucChars : “AÄÁÀÂÃÅĂĄÆBCÇĆČDĎĐEÉÈÊËĚĘFGHIÍÌÎÏJKLĹĽŁMNÑŃŇ” & ¬
“OÖÓÒÔÕŐØPQRŔŘSŞŠŚTŤŢUÜÚÙÛŮŰVWXYÝZŽŹŻÞ”

Instead of copy it in my script, I’d like to access it. But I don’t know every AppleScript tricks (I used to be a Flash dev during many years) and maybe there is another way ?

Thx.

#6

The simplest way is to use the my keyword:

character 1 of my ucChars

Similarly setting:

set my ucChars to "thisIsAnUglyAndFragileWayOfChangingCase"
#7

Would something like this suffice?

use AppleScript version "2.4" -- Yosemite (10.10) or later
use scripting additions

set theChars to "AÄÁÀÂÃÅĂĄÆBCÇĆČDĎĐEÉÈÊËĚĘFGHIÍÌÎÏJKLĹĽŁMNÑŃŇ
OÖÓÒÔÕŐØPQRŔŘSŞŠŚTŤŢUÜÚÙÛŮŰVWXYÝZŽŹŻÞ"

(*following 3 lines return a comma delimited list*)
set {saveTID, AppleScript's text item delimiters} to {AppleScript's text item delimiters, ","}
set theList to items of theChars 
set AppleScript's text item delimiters to saveTID

set myChar to (choose from list theList) as text -- StandardAdditions.osax
#8

Well, not sure to understand…

My property property ucChars : “AÄÁÀÂÃÅĂĄÆBCÇĆČDĎĐEÉÈÊËĚĘFGHIÍÌÎÏJKLĹĽŁMNÑŃŇ” & ¬
“OÖÓÒÔÕŐØPQRŔŘSŞŠŚTŤŢUÜÚÙÛŮŰVWXYÝZŽŹŻÞ” is in a lib “Script A” and I’d like to use it in “Script B” like :
on run
tell script “Script A”
log (ucChars) – does not work
end tell
end run

The only way to get the property is (if i’m not wrong) to create a getter like :
on getUCChars()
return my ucChars
end getUCChars

It is why I asked my question to create that getter automatically with a snippet like in Eclipse.

Thx.

You failed to mention that you meant a property within a script library — that’s quite a different thing.

The short answer is:

tell script "Script A"
	log (its ucChars)
end tell

But that’s not a very good way to address script libraries — you’re generally better off using a use statement. And you also need to be aware that if you’re setting library properties, they are shared between all scripts that access them from the same AppleScript component instance.

#10

The short explaination is : I just want to create a constant in a class and use it in another instead of create it again.

What is the trick with the « use » keyword ?

Thx.

#11

I wouldn’t call it a trick, but this is typical:

use AppleScript version "2.4" -- Yosemite (10.10) or later
use scripting additions
use scriptA : script "Script A" version "1.0"

log (scriptA's ucChars)

The version is optional. The assigned variable after the word use is also optional — you don’t need it if the script defines terminology, for example — but when provided is a property of the script.
