Diff command issue

[Rajesh Natarajan]

I am getting this error when i use diff command to compare source & target files. what ext do i need to include ?

multiline-text-diff graphman extension is not enabled, falling back to the default

@Rajesh Natarajan

graphman client (diff) provides multi-line text differences as an extension. To see this functionality working, 

• install the corresponding third-party npm module
• and enabled it using --options.extensions 

Please check the below wiki page for more details.

Hi Rajesh.

Potentially some additional info:

In my understanding, the message you get is just a hint, that the extension is not available. It's not an error.

The multiline-text-diff extension provides policy/service "code" diff results.

This capability is related to the approach to treat "policy as code", where it might be in interest, to not only get aware that policies are different (the default behavior), but to get information about where exactly they differ, which assertions are different.

Hope that helps a bit as well.

Thanks for the quick response Michael & Raju. yes I want get deep dive in to the difference at assertion level. I tried the option which is there in GIT. I am getting module not found exception. Not sure how to get that module 

[Raju Gurram]

Sorry for the late reply. 

Did you forget to install the required npm module? if yes, please install the module using the below command

• npm install diff@5.2.0 --global

[Rajesh Natarajan]

I did that install. still that module is not loading & I am unable to see Assertion level diff

[Raju Gurram]

Did you install the module at global level?

you may double check that using below command

npm list --global

It will list the installed npm packages at global level

+-- @layer7/graphman@1.3.11
`-- diff@5.2.0

[Rajesh Natarajan]

Yes I see that bundle in list

[Raju Gurram]

Not sure what's wrong in that case. We need to understand more about your environment like windows/node/npm versions.

Maybe, we can meet via google/zoom meet tomorrow.

[Rajesh Natarajan]

Sure we can meet. I raised a support ticket (36103315) if you want to track .
