In the example workflow above, you can see that we used the "Ask for Text" action to ask for user input that would set the variable's value. We then drag the variable's token from the Variables panel to the "Save as:" field in the "Take Video Snapshot" action. This token acts as a place holder for the text that was inputted by the user. When the workflow is run, the token or "placeholder" will be replaced with the value of the variable. But how does this benefit me? Variables can benefit you in many ways. For instance, if you have large workflows with multiple actions, then you can use a variable to fill in information in many different locations, but you only have to supply the information to Automator once.

This can often save time wasted from inputting text. If this is your first time using variables in Automator, don't be scared. I will be providing many walk through tutorials similar to the " Mac Automation: take and sync pictures to Apple TV " tutorial that I showed you. Many more tutorials just like these can be found right here on TUAW.

Now that the original filename is stored in a variable, you need to retrieve it from the variable after finishing with the 2x version. Find Get Value of Variable from the actions list, drag it onto the bottom of your workflow, and make sure the Variable selected is Original Input.

All actions on the workflow return an output. To fix this, you can disconnect an action from previous outputs. Now you can finish this up by adding another Copy Finder Items action under the Get Value of Variable action and setting it to your Processed folder. In your Processed folder, file names are unchanged. Well done! You now have full control over your image assets. Besides working with Retina, you can use this same process to prep images for iPad, iPhone and iWhatever.

To do this, all you need is the ration or change for each device, and a single high resolution image. Beyond that, you can even automate actions for photo manipulation. For example, you can add filters, like posterize and vignette. If you need to use a database within your app, the most likely format is SQLite. Using Automator can make managing the database more efficient. In Automator, select File from the menu bar and then New. Note that one is included in the sample files for this tutorial. Drag a Execute SQL action onto your workflow.

This can run any SQL you want on the database. When this action runs, its output will be the result of the query. Click the Run button at the top right to see what happens. Feel free to experiment with the View Results action to fully understand what the output of each action is.

For example if you were to drag it above Execute SQL , the result would be something like:. The output of the Get Specified Finder Items action will be the filepaths of all files included in the action. You could use a Folder Action to handle this, but the sample project requires you to work with multiple files of different natures, specifically a CSV file and a SQLite database.

Applications are just like every other application in your applications folder. They are single files which can take an input by drag and dropping a file or folder onto them:. The idea is your app will be a names database for smart people, so you need a table to store names. This query will create your table with the name people and will contain two fields: first name and last name.

Now that you have added the People table to your database, you can create an application to automate adding CSV data. In Automator, go to File then New from the menu bar. This time, select Application. They are text files where each line represents a new row of data and a comma separates each field. The one located in the sample file looks something like this:.

The CSV file will pass in as the first output to connect to. Next, you need to add a few actions to format the text, convert it to SQL and store it in a variable. The first action to add is Combine Text Files :. This is necessary in case you drag multiple CSV files into the application; it will loop through the contents of each text file and combine everything into one.

Enter the following SQL on each:. If you were to run this action on the sample names.

Next, add a View Results action to your workflow. Having a View Results action seems to mitigate the bug. The workflow should now look like:. Now what you need to do is set it up so the user which will be you in a moment picks a database for the SQL, then apply the SQL to the chosen database. Add an Ask for Finder Items action to your workflow, this will allow you to select the database where you wish to run the SQL statements. Name the new variable SQLite Database. Save the file somewhere on your Desktop for easy access. To test it out, drag and drop your names.

It will then ask you to supply an SQLite database :. Look at you! You now have experience with all of the available SQL actions. Is your mind overflowing with ideas on how to use them to automate your database related projects? It should be! Combine that with the power of AppleScript and you can do some pretty nifty stuff. The input at the end of the Run Applescript action is actually an array of all data collected prior to this action in the workflow.

To use these inputs, you need to assign them to a variable in your AppleScript. You can assign variables with either set or copy, followed by the name of the variable. You can assign it a value straight away, above where you assign the value of the first item in the array of inputs. If you have multiple variables, they are available based on their position in the workflow:. Select Variables in your library and search for Documents and drag it onto your workflow. What a crap!! It will be easer to use rsync on a script Why do you accept all this crap?
