Search a String: Offset

There are a lot of handy string functions in most languages. You can find a list of equivalents for various Python string functions here. One commonly used string function is offset, which can find a string. If you are searching for the word “needle” in a string variable called “haystack” then doing this:

offset of "needle" in haystack

will return the start position of “needle” and if it doesn’t find needle at all, will return 0.

    Text manipulation is definitely not one of AppleScript’s strong points, and its out-of-the-box support for it really sucks. However, if you’re working in Studio you can easily take advantage of Cocoa’s own NSString methods and third-party text processing frameworks such as RegexKit. For example, to uppercase an AppleScript string:

    set myText to call method “uppercaseString” of myText

    For non-Studio-based projects, your best bet would be to use a Unicode-aware scriptable text editor, e.g. TextWrangler, or scripting addition/scriptable faceless background application, e.g. TextCommands.

    Intersting, I can’t seem to get that call method command to compile in a test application.

    If cutting and pasting, beware WordPress’s curly quotes. AppleScript requires straight double quotes for string literals.
