Engineering for the real world

Applescript in iWork

Applescript has the potential to significantly improve many work flows. Like all programming or scripting languages it does have a learning curve, but because of the simple structures and plain language the curve is one of the easiest languages to learn. The real power of the language is its ability to interface between different programmes allowing data to be transferred from one application to another. It is also a quick way of creating similar tools to Macros that are used in Microsoft Office.

It comes as a surprise that one of Apples flagship applications, iWork, does not fully support Applescript. Neither Pages nor Numbers have applescript dictionaries associated with them, although Keynote does have a dictionary. This means that Pages and Numbers do not have publicly documented specific Applescript abilities. The good news is that this doesn't mean that Applescript can't be used with this applications.

Using the 'application' System Events you can easily control keystrokes, and occasionally buttons within most applications. To demonstrate how this is done, the following simple script is used to insert a standard reference into the active Pages document. Applescript Studio can then be used to create an interface which allows different references to be inserted all at the click of a button.

set the_text to "Hoek-Brown failure criterion - 2002 edition, 2002, E.Hoek; C. Carranza Torres; B. Corkum, Proc. NARMS-TAC Conference, Toronto, 2002, 1, 267-273, www.rocscience.com/hoek/references/H2002.pdf"
set the clipboard to the_text
tell application "System Events"
tell application "Pages" to activate
tell process "Pages" to keystroke "v" using command down
end tell


I find this script a real timesaver because I don't have to look up references every time I need to insert them into a document. All it takes is a simple click of a button.


Omnigraffle template for geological sequences

Omnigraffle is one of the best tools I've found for creating engineering diagrams. Whilst it is powerful, it is also quick and easy to use and you can copy and paste PDF's straight from Omnigraffle into either Keynote or Pages. This keeps the quality and opacity of the diagrams that have been created.

One of my favourite features of Omnigraffle is the ability to create your own templates. One of the most useful diagrams I work with is a standard borehole logging diagram. The patterns used in this diagram are from British Standard 5930 which means diagrams will be professional quality as well as quick to produce.
