Hopefully deserves to be simpler than the preprocessor :)



At first I was annoyed that things like this didn't work:

[set_variable]

name=foo

format=$array[$i].x

[/set_variable]

Arrays were not handled properly in it. (Using to_variable and if necessary
multiple [set_variable] tags can get the desired result, but it's
unnecessarily clumsy.)



Anyway I rewrote the algorithm and I can't imagine any situation where it
would be wrong, except possibly one, when there are two variables next to
each other. Even in that, there just has to be a pipe (|) character in one
place:

[set_variable]

name=bar

format=$var1|$var2 #not $var1$var2

[/set_variable]



However I did a search and I do not believe such a pattern of two variables
being used adjacent to each other has ever been used. Almost always some
other character is put between two variables' usages. And if it's really
desired to do so, it's as simple as putting a pipe character in between.

Hooray for string utils having been separated into a separate file
