In my DSL, I have to handles some wildcards inside of strings.
To avoid conflichs with normal text, I decided to enclose these in "«" and "»".

The only issue is that the user has to enter these characters when editing his DSL file.

ALT0171 and ALT0187 doesn't seem the best way to do it, but I can not provide some Editor Templates inside of a string.
So is there any (minimal effort, because I'm still a newbie in eclipse) alternative like:
hit "CTRL-<" to enter "«" ?

I think I saw this feature when I edit my xxxGenerator.xtend

TIA, Uli

Hi

Xtend uses guillemets and I think that it was a good design decision however typing them is a nightmare. I have Googled occasionally for help and found rather confusing documentation, certainly the Xtend documentation is not helpful. It seems that part of the problem is Windows-specific and maybe even keyboard-specfic and so simple prefixes don't work for me. I resort to copy-and-paste from a file where the guillemets exist.

It would be nice if Xtend introduced some clear short cuts.

Regards

Ed Willink

Hi Ed,

there is some hope because when I edit an XTEND file, typing CTRL-< will result in a "«" (hip hip hooorayyyy!)
The question is only how I can activate the same functionality inside of my little DSL editor.
Perhaps some insider may give us some clue what needs to be done.

do you mean

<extension
         point="org.eclipse.ui.bindings">
      <key
            contextId="org.eclipse.xtend.ide.XtendEditorScope"
            schemeId="org.eclipse.ui.defaultAcceleratorConfiguration"
            sequence="M1+&lt;"
            commandId="org.eclipse.xtend.ide.insertLeftGuillemet">
      </key>
      <key
            contextId="org.eclipse.xtend.ide.XtendEditorScope"
            schemeId="org.eclipse.ui.defaultAcceleratorConfiguration"
            sequence="M1+&gt;"
            commandId="org.eclipse.xtend.ide.insertRightGuillemet">

Hi Christian,

that looks pretty promising as a start. I will experiment how this can be converted to work in mydsl example.

Thanks a lot, Uli

P.S: I found in the github the plugin.xml as well as the Handler under

xtext-xtend/org.eclipse.xtend.ide/src/org/eclipse/xtend/ide/edit/InsertStringHandler.java

Now I have to find out how to transfer that to my own little mydsl example project
