DABL - viewing templates from packages

App Development
,

Hi, I noticed that in DABL, users can view the template source code once a package is uploaded. Just curious which part of the Daml SDK did that? Is that function available on Daml assistant?

By default, the Daml source code is packaged along the compiler output in the DAR file produced by daml build, as you can see in this example:

> daml new --template create-daml-app create-daml-app
> cd create-daml-app/
> daml build
Compiling create-daml-app to a DAR.
Created .daml/dist/create-daml-app-0.1.0.dar
> unzip -l .daml/dist/create-daml-app-0.1.0.dar | grep '\.daml'
Archive:  .daml/dist/create-daml-app-0.1.0.dar
