[SOLVED] Pureconfig - is it possible to include in conf file another conf file?

Pureconfig - is it possible to include in conf file another conf file?

Is it possible to include in *conf file another conf file?

Current implementation:

// db-writer.conf
writer: {
  name="DatabaseWriter",
  model="model1",
  table-name="model1",
  append=false,
  create-table-file="sql/create_table_model1.sql",
  source-file="abcd.csv"
}

Desired solution:

// model1.conf + others model2.conf, model3.conf..
table: {
 name="model1",
 table-name="model1",
 create-table-file="../sql/create_table_model1.sql"
}

//db-writer.conf
import model1.conf       <=== some import?
writer: {
  name="DatabaseWriter",
  model="model1",        <=== some reference like this?
  append=false,
  source-file="abcd.csv"
}

Reason why I would like to have it like this is :

to reduce duplicated definitions
to pre-define user conf file which are rare modified

I guess it is not possible - if not do you have any suggestion how to separate configs & reuse them?

I'm using scala 2.12 lang and pureconfig 0.14 (can be updated to any newer)

Solution

Pureconfig uses HOCON (though some of the interpretation of things like durations differ). HOCON include is supported.

So assuming that you have model1.conf in your resources (e.g. src/main/resources), all you need in db-writer.conf is

include "model1"

HOCON-style overrides and concatenation are also supported:

writer: ${table} {
  name = "DatabaseWriter"
  model = "model1"
  append = false
  source-file = "abcd"
}
