69 +The generated code includes a parser for text files in your syntax. This parser is simply used with the same interface as for any other EMF models: resource sets. Your final task for this tutorial is to reuse the Turing controller you implemented in the EMF tutorial for simulating Turing Machine models, this time applying it to {{code language="none"}}.tuxt{{/code}} text files. However, instead of using a fixed path to your model file, we will now use a //menu contribution// in order to set the file path dynamically.
70 +
71 +1. Go to the plugin where you created and registered {{code language="none"}}TuringHeadController{{/code}}, the Turing Machine simulator. Open {{code language="none"}}plugin.xml{{/code}} → //Dependencies// and add org.eclipse.ui if not on the list yet. Go to //Extensions// and add org.eclipse.ui.menus.
72 +1. Add a //menuContribution// element to the new extension and set "popup:org.eclipse.ui.popup.any?after=additions" as //locationURI// (without quotation marks).
73 +1. Add a //command// element to the //menuContribution// with the following attributes:\\
74 +1*. //commandId: //de.cau.cs.rtprak.login.setSimFile
75 +1*. //label: //Set Simulation File
76 +1. Add a //visibleWhen// element to the //command//, and add an //iterate// element to the //visibleWhen// with the following attributes:\\
77 +1*. //operator~:// and
78 +1*. //ifEmpty~:// false
79 +1. Add an //adapt// element to the //iterate// with the following attribute:\\
80 +1*. //type~:// org.eclipse.core.resources.IResource
81 +1. Add a //test// element to the //adapt// with the following attributes:\\
82 +1*. //property~:// org.eclipse.core.resources.extension
83 +1*. //value~:// tuxt
84 +1. Add a new extension org.eclipse.ui.commands and add a //command// element to it with the following attributes:\\
85 +1*. //id~://de.cau.cs.rtprak.login.setSimFile
86 +1*. //name~://Set Simulation File
87 +1*. Click on //defaultHandler// to open a dialog for creation of a new handler class. Name the new class {{code language="none"}}SetFileHandler{{/code}} and put it into some package of that plugin. Remove the suggested interface and set {{code language="none"}}org.eclipse.core.commands.AbstractHandler{{/code}} as superclass instead.
88 +1. (((
89 +Use the following method stub for SetFileHandler{{code language="none"}}{{/code}}:
90 +

92 + /**

95 + @Override
