You can use command `dub describe` to get all information for a 
dub project. It has some arguments to filter for specific 
information and on linux you can of course use jq to filter out 
any information from the json produced by `dub describe`.

Kind regards

Thank you for your answer, but I want to put the application 
version in variable in the application code automatically during 
compiling process.

 version in variable in the application code automatically

Ok, now I understand. My approach for this is to specify in 
dub.json `preGenerateCommands` which calls a .cmd on windows and 
a .sh on posix. The scripts generate a d module and reads the dub 
package version from environment variable DUB_PACKAGE_VERSION and 
writes them into a enum.

You could also have a look at dfmt or DScanner. They do s.th. 
similiar.

Kind regards
Andre

AFAIK, that's not passed directly to the application. And the version is 
not actually stored in the dub.json file (it's a tag on git). I think 
you would have to use git to get the information.

If you want the versions of the dependencies, it's in the 
dub.selections.json file. It's probably possible to import the file and 
parse the json directly.
