NSIS用斜线连接字符串

Question

I'm trying to build a string with this expression bla://${foo}/bar where ${foo} == "hostname" . The expected result is bla://hostname/bar but I get http://${foo}/bar instead. So I figure there is something special about the combination /$ but I can't figure it out.

Thanks for your help

Answer 1

/$ is not special but a define that does not exist ends up as ${definename} .

DetailPrint "${foo}" ; Prints ${foo}
!define foo example.com
DetailPrint "${foo}" ; Prints example.com

All defines are resolved at compile time, if this hostname is something the user could configure on a custom page you need to use a NSIS variable...
