The real rule is more complicated. Letters are spanned. Isolated (not two in a row) periods not at the end (except there is a case where it can be) are included. Balanced brackets ([]) are also spanned. This is described in comments in do_interpolation in src/serializable/string_utils.cpp (the names are from memory, but should allow you to find the routine). The reason for this is to allow arrays to be interpolated. This even works if the subscripts are also variables. _______________________________________________ Wesnoth-dev mailing list [email protected] https://mail.gna.org/listinfo/wesnoth-dev
