Default TTD string as substring?

[andythenorth]

NML won't compile this: "Expected a (literal) string".

string(STR_EXTRA_TEXT_SECONDARY, string(STR_EXTRA_TEXT_SECONDARY_CARGO_SUBSTR_THREE_INPUTS, string(STR_EXTRA_TEXT_SECONDARY_CARGO_SUBSTR_DETAIL, TTD_STR_CARGO_SINGULAR_COAL, string(STR_EMPTY)), string(STR_EXTRA_TEXT_SECONDARY_CARGO_SUBSTR_DETAIL, TTD_STR_CARGO_SINGULAR_COAL, string(STR_EMPTY)), string(STR_EXTRA_TEXT_SECONDARY_CARGO_SUBSTR_DETAIL, TTD_STR_CARGO_SINGULAR_COAL, string(STR_EMPTY))), string(STR_EXTRA_FLOUR_MILL, string(STR_EXTRA_FLOUR_MILL_GRAIN_SUBSTR), string(STR_EMPTY)))

This is triggered by the substring use in:

STR_EXTRA_TEXT_SECONDARY_CARGO_SUBSTR_THREE_INPUTS :{STRING}{}{STRING}{}{STRING}{}

The compile succeeds if I swap 'TTD_STR_CARGO_SINGULAR_COAL' for something like 'string(STR_FOO)'.

Default TTD strings can't be used in substring substitutions? Or the syntax is wrong?

It's a pretty horrible stack of substrings eh, but will save translators a lot of time if it works

The solution to this was to use the text stack, instead of substrings.
