Is it possible to append a previously defined value?

[sahilseth]

It is possible to ask the final parser to pick up a previously defined value, and append to it?

[tool]
basepath = "~/apps/mytool"
binpath = "{basepath}/bin"

Finally, I expect the value tool.binpath='~/apps/mytool/bin'

I am using the rcpptoml parser, and not sure which is the best repo to raise this issue.

Thanks for nice clean config lang!

Unfortunately it's not possible in toml. You cannot reference another variable.

Hi @sahilseth! Thanks for filing this issue.

I don't think this is something we'd want to have in the TOML standard since this is something that can be implemented by tools that consume TOML, as additional behaviour of the tool. I understand that it might be a common use case, but the way to satisfy this would be to address it at the application level and not the TOML language level.
