This is located on the ten key number pad on desktop computers and next to the "Command" key to the right of the space bar on laptops. As your script becomes writing applescript complex, a bit of organization is in order.

By typing two dashes "--" before a line of text, you can insert a comment. Use comments to separate and describe your sections writing applescript code for easy navigation. Notice that you can perform mathematical operations on variables.

Also notice that you can change a variable after it is declared.

Your Answer

Immediately after setting "theAnswer" to the sum of "theFirstNumber" and "theSecondNumber" resulting in 5I changed the value of "theAnswer" by adding one to it resulting in 6.

If you run this script you should see the following result: Some Basic Math Again, this only scratches the surface of the kinds of operations you can perform on variables. Much of the power of behind any programming language is the ability to manipulate variables to perform a wide variety of tasks.

The Key to it All: AppleScript Dictionaries Though AppleScript itself has a wide range of commands that can be applied to any program or item in OS X, the developers of each application are tasked with adding full AppleScript support to their apps.

What this means is that developers must write simple manuals for how to communicate with their applications through AppleScript. These manuals are called "Dictionaries". Scroll down the list of applications, click on Mail and hit "OK".

You should see the following window: The Mail Dictionary The column on the left contains the available "Suites" of commands and items.

You can narrow this preview by clicking in the second column, then again in the third. Suites contain commands C with a circle and classes C with a squareclasses contain properties P and elements E. Create an Algorithm for Our Script First we need an algorithm, which is a fancy way to say that we need write down exactly what our script will do.

We want to create a script to compose and send an email. As we write our algorithm, we need to keep in mind the way AppleScript works. Here are the steps I came up with: Create a variable that holds our new message along with its various properties Create the new message Send the new message Step 2: Be sure to put your own email address in the recipientAddress variable so you can ensure that the the script is working properly when you receive the email.

Create the Message Variable with the Mail Dictionary Since we have no idea how to tell Mail to create a new message, this is where we need to refer to the AppleScript dictionary.

Knowing that we want to "create" a new message, we just scroll through the options and find something equivalent. That sounds perfect, so we now know to tell AppleScript we want to "make" something. Next click on the "Mail" suite.

Now click on the "outgoing message" class and look at the available properties down below. We now know the proper syntax to refer to these properties.

Notice that the dictionary gives you the format to define the properties. About halfway down the list of classes we find "recipient". Click on the recipient class and we see that once again, we can use plain English to refer to the properties of the recipient. You can use the search feature to hunt down properties, classes, elements and commands quickly.Generally, if you want to do anything with a file or folder, it must be a complete alias reference.

Just change as file specification to as POSIX file as alias and that part will work!. Also, remove the as list and delete the line set eof of the_file to tranceformingnlp.comng the file already contains information, you're basically telling the script that the end of the file is the beginning of the file.

AppleScript Essentials Working With Text. Writing to a File. To write data to a file, you use the write command, also found in the File Read/Write suite. When using the write command, it is always necessary to use the open for access command prior to writing to the file.

You cannot write to a file unless it has been opened first.

This step-by-step tutorial, exerpted from the Apple Training Series book AppleScript , is an easy and fun way to learn the basics of AppleScript while writing simple scripts.

WEBSITE HISTORY • Added new section about SQLite & Numbers. AppleScript is an English-like language used to create script files that control the actions of the computer and the applications that run on it. Much more than just a macro-language, which simply repeats your recorded actions, AppleScript scripts can "think.".

Apple describes AppleScript as "an English-like language used to write script files that automate the actions of the computer and the applications that run on it." I'd add that AppleScript is the easiest scripting language to learn, because it's so similar to English and it's very easy to understand.

Every day, businesses and individuals alike use AppleScript to create newspapers and books, manage networks, build DVDs, process images, generate web pages, backup files and folders, make videos, and much more. AppleScript is the most powerful, easy-to-use, automation tool available on any platform.
