How to disable validation when editing in xtext editor? [message #1840349]

I have implemented a dsl editor based on xtext.

when the code of my dsl are more than 300 lines, the user experience of my xtext editor is getting slower and slower.

The xtext editor was blocked for serveral seconds when the validator was running.

How to disable validation when editing ? And How to enable validation after saving ?

Thanks!

Hi,

first you should profile where the time is spent and if validation is the problem at all.
second you should have a look at your check methods
and mark them with @Check(Check.NORMAL) instead of the default @Check which will be CheckType.FAST and be executed during editing. NORMAL will be executed on save

David,

Please read the section "Creating Custom Validation Rules" from the Xtext documentation - https://www.eclipse.org/Xtext/documentation/103_domainmodelnextsteps.html
