Hello,

I have templates that are created using a template programming language developed on xText. I want the templates to appear as a menu. I dont want to treat the templates as strings, rather should maintain their structure.
I thought of enumerating the templates, but then they become strings...

Can someone suggest me a technique, and idea?

Tnx a lot.

Hi,

can you please elaborate a bit more: why "they become strings" - what are you doing?

Does the view "Navigate/Open Model Element" show roughly what you need in you menu?

Tnx for replying Razz

My ultimate goal is to build an ontology for writing/to construct a restricted sentence. So I started with a simple template language that allows me to create templates as shown below.

Template:
template1 <someone> likes <a pet>
template2 <a pet> likes <something>

I have hundreds of these templates. I want to have a menu that holds these templates. These allows me to select a template, and fill the placeholders in order to complete the sentence.

in my grammar i have:
UseTemplate:
template=[Template];

However, the scoping only shows me template1, and template2 (the intantiations). I want the template itself to be displayed just like a menu.

I am just beginning to learn xText. I hope this clarifies better. Tnx

Nas

I couldnt find a good reference on the internet for it.

That is correct: a template should be selected, and inserted. When this happens,

first preference: reserve the structural integrity of the template
second preference: treat the template as a string, if first choice is too complicated.

Do you think manipulating the content assist of the default xText editor could help?

Hi i am still not sure if i get your usecase. Did you have a look at the eclipse template mechanism as xtext supports it by default? You could fill that programarically as well.

To understand better what you want to do. Can you share asample template grammar and usage grammar and sample template model file and sample model dile before and after inserting the template

Hello,

the grammar

Type:
Livingthing
;

Livingthing:
'datatype' name=ID
;

Template:
"Template" name=ID
('<name=ID':'type=[Type]'>' 'likes' <name=ID':'type=[Type]'>)
;

UseTemplate:
template=[Template] // Here, "template" is a reference of type"Template". Rather, I want to have it as a menu of templates.
;
...

In the editor, I create

/* Declare types */
datatype People
datatype animal

/* crerate the template */
Template template1 <name:People> likes <name:animal>
Template template2 <name:animal> likes <name:people>

/* use the template */
I prefer to have a menu that holds the templates. Then select, and fill the placeholders (<xx:type>).

Thank you for your support Smile

Regards,
Nas

Hi,

this makes only sense if the structure of the template is very similar to the one of the usage.
you can programatically add templates by adapting DefaultTemplateProposalProvider.

You can add own variables by adapting XtextTemplateContextType

Hi Nas,

I created Luecken(x)text which uses textblocks with a syntax similar to the Templates in Eclipse.
It is published as 3 (german) articles in "Eclipse Magazin"
and they bundled it as a "shortcut" https://entwickler.de/press/dsl-mit-xtextxtend-126643.html

Perhaps this may give you some ideas.

Greetings from Frankfurt/Germany,
Uli

Due to time limitation, for know I am using xText default template proposal (from the preferences).
Of course, that wasn't my initial intention to do. But I will try to do what you guys have suggested me.
I am sure I will come with some results sometime later.

Thank you.
Cheers,
Nas
