to convert a string into an integer

How do I do that? I want to convert a string into an integer with Applescript…

thanks

#2

Is this too simplistic, I might be missing the point…

set myString to "12345"
myString as number

(and what am I doing wrong with the Applescript button? It doesn’t look right when I preview!)

#3

Thanks, …

this my code :
set open_file to choose file with prompt “Choose a file containing the messages”
set file_path to open_file as string

set file_rate_size to size of the open_file
set file_rate to file_rate_size as number

I want to open a file, and from that file I want to get the size and I want to check on the size…
that size is integer right?

thanks!

I get ‘Can’t get size of alias [path to file]’

But I’ve never been able to get my head around this whole file/alias business. Sorry I can’t help more.

It’s nothing! Thanks for your thinking and help! I’m getting crazy of this topic! but I never give up and I shall find the answer! I will try that what you said!

thanks! & grtz

Yes, but you won’t get that that way. ‘choose file’ returns an alias value, which identifies a file (or folder or disk) on your filesystem. To do manipulate the file/folder itself you need to use various commands supplied by Finder or by Standard Additions, passing them that alias value so they know which file to work on. Examples:

  • To get a file’s size using Standard Additions’ ‘info for’ command:
set the_file to choose file
size of (info for the_file)
  • To get the length of the text in a plain text file, use Standard Additions’ ‘read’ command to read that text into AppleScript as a string or Unicode text value, then get the length of that:
set the_file to choose file
length of (read the_file as string) -- for a MacRoman-encoded [1] text file

set the_file to choose file
length of (read the_file as «class utf8») -- for a UTF8-encoded text file

set the_file to choose file
length of (read the_file as Unicode text) -- for a UTF16-encoded text file

(Note: in the above examples, the ‘as [class]’ bit is a parameter to the ‘read’ command that tells it how to read the file, not a coercion applied to the value of variable ‘the_file’.)

  • To get the length of the text in non-plain text files (.rtf, .doc, etc.) you’ll need to open them in a suitable application and ask the application to measure their length, e.g.:
set the_file to choose file -- e.g. an RTF file
tell application "TextEdit"
	open the_file
	count characters of text of document 1
end tell

[1] Or MacCyrillic, MacJapanese, or whatever other crusty old legacy encoding your system supports - it depends on your International settings. For North Americans, western Europeans and Antipodeans it’s generally MacRoman.

You can also just use the Finder:

set open_file to choose file with prompt "Choose a file containing the messages"

tell application "Finder" to set file_rate_size to size of the open_file
#8

I think I was beaten to this: but anyway…

tell application "Finder"
	set open_file to choose file with prompt "Choose a file containing the messages"
	set theInfo to info for open_file
	set sizeBytes to size of theInfo as integer
end tell

the only think it does do differently is give toy the size as a whole number - instead of the “3.60855E+5” way…

#9

The ‘tell Finder’ block is actually redundant here as you’re using Standard Additions commands only.

Thanks!

i’m going to try those solutions!
