re-generate captured text [message #953437]

Hi, is there a way to generate back from an object of the parse tree the text that was consumed by the parser to instantiate such object?

Example:
Grammar:

...
Func: "f" "("arg=ArgSpec")";

ArgSpec : ...
...

Document

f( 5*PI )

Given the ArgSpec instance (which is possibly a complex type with properties etc) I would like to simply generate the string "5*PI", without manual processing all the fields of the ArgSpec instance

I hope it's clear
Thank you
B

Hi,

if i get you write you have a parsed eobject in your hand and want to access the text that was parsed.
you get access to the node model through the NodeModelUtil class.

Thank you!

So far, I found these

NodeModelUtils::getTokenText(NodeModelUtils::findActualNodeFor( <my eobject> ))

NodeModelUtils::findActualNodeFor(<my eobject>).getText()

which seem to work

thanks again
B
