![]() ![]() For that, you really need AppleScript Studio, which is a part of Apple's Developer tools, or FaceSpan from DTI. You do not make a full GUI application just because you use an. app, then a double-clickable application, or droplet (a special AppleScript that runs when files or folders are dropped on it), is created. If you don't use a name, then the output file is a.scpt, and it's placed in whatever directory you happen to be in. □ -o enables you to specify the name of the script file to be created. As long as the input file is valid code for the language you're using, osacompile will use it the same way that Script Editor will. To specify an input text file, simply place the path to the file after all the switches in the osacompile command, and it will use that as an input file. Obviously, this is not going to be the way you want to create a large script the quoting and escaping alone will make you quite insane (not as insane as my former co-worker who composed personal letters in raw PostScript code, but close). A multiline command would look like osacompile -e 'display dialog "boo"\display dialog "who"' and would create a compiled script with two separate commands: display dialog "boo" and display dialog "who". Note how the full command is enclosed in single quotes and the text part of the command is in double quotes inside the single quotes. For example, a single line script to display a dialog box would look like osacompile -e 'display dialog "boo"1. You can use multiple lines here by using the forward slash (\) character in the script command. This can be tricky because AppleScript uses a lot of characters that need to be escaped or properly quoted to make it past the shell correctly. □ -e enables you to enter the script commands as part of the statement. ![]() For example, if you want the script compiled as JavaScript, use osacompile -l JavaScript. □ -l enables you to specify the language in which you want the script compiled. osacompile has a nice set of switches that give you a lot of power (see the man osacompile page for full details), but the following list shows the major switches: JavaScript while using AppleScript as a fallback by taking the output of osalang and using that to test for the languages you want. You can also specify the OSA language you wish to use in fact, you can even use different languages depending on the capabilities of the system you're running. This command enables you to create a compiled script, or script application, from shell input or a text file. Osacompile is the second part of the command line AppleScript trio, and a very powerful one. Therefore, if you need a specific OSA language, osalang is a handy way to test for that. The preceding command would return the following: For example, to look for JavaScript and get its feature set, you use the following: In other words, by using osalang and grep, you can test for a given language or set of capabilities. "convenience" APIs to execute scripts in one step. Manipulating the event create and send functions. The capabilities of the languages translate as follows: The output shows that I have a few different potential languages with different capabilities.

If I run osalang with the -L switch on the Mac on which I'm writing this chapter, which gives me all the available languages and their capabilities, I get the following: □ osascript osalang is the command that enables you to see what OSA languages are installed on a given Mac. You can use three shell commands to connect a shell script to AppleScript: What if you can't prebuild the script ahead of time, or you need to talk to the shell environment from AppleScript? Worry not, Apple has taken care of that. How do you actually link AppleScript and shell script together? As you saw in the earlier example, you can use a shell script to start an AppleScript application. ![]()
