Possible to pass Variable to angular.json and avoid code duplication?

Question

I am looking for a way to pass information to angular.json file so that I do not need to repeat build configurations and avoid all the code duplication. I can not explain well so I'll try with an example. So In my angular.jsonunder configurations I have something like

"configurations": {
"de": {
              "aot": true,
              "i18nLocale": "de",
              "i18nFile": "project/src/locale/messages.de.xlf",
              "i18nFormat": "xlf"
            },
            "en-gb": {
              "aot": true,
              "i18nLocale": "en-gb",
              "i18nFile": "project/src/locale/messages.en-gb.xlf",
              "i18nFormat": "xlf"
            },
            "en-us": {
              "aot": true,
              "i18nLocale": "en-us",
              "i18nFile": "project/src/locale/messages.en-us.xlf",
              "i18nFormat": "xlf"
            },
            "es": {
              "aot": true,
              "i18nLocale": "es",
              "i18nFile": "project/src/locale/messages.es.xlf",
              "i18nFormat": "xlf"
            },
            "fr": {
              "aot": true,
              "i18nLocale": "fr",
              "i18nFile": "project/src/locale/messages.fr.xlf",
              "i18nFormat": "xlf"
            },
            "it": {
              "aot": true,
              "i18nLocale": "it",
              "i18nFile": "project/src/locale/messages.it.xlf",
              "i18nFormat": "xlf"
            },
            "pt-br": {
              "aot": true,
              "i18nLocale": "pt-br",
              "i18nFile": "project/src/locale/messages.pt-br.xlf",
              "i18nFormat": "xlf"
            }

Is there a way to have a variable like lets say i18n and I can use it in angular.json like $i18n :

"configurations": {
"i18n": {
              "aot": true,
              "i18nLocale": "$i18n",
              "i18nFile": "project/src/locale/messages.$i18n.xlf",
              "i18nFormat": "xlf"
            }

I am not good with english. I hope I explained well using the example for what I am looking for. Thanks in advance.

Unfortunately, you can't have this. See stackoverflow.com/questions/23869882/… — AkshayM

I don't speak angular, but in the hope this is useful, I think you're looking at this something like this:

echo '["de","en-gb","en-us","es","fr","it"]' | jq '
  {"configuration":[ .[] as $c |
    {
      ($c):{
         "aot":true,
         "i18nLocale": $c,
         "i18nFile": ("project/src/locale/messages." + $c + ".xlf"),
         "i18nFormat": "xlf"
      }
    }
  ]}'

This command uses jq command line parser to forge a JSON configuration according to your first example.

You can grow the table sent by echo to jq to any country string and get as many configurations.
