Hi Adrian,
Filenames can be functions that are executed every time the file is
created, something like this:
```
def my_filename() =
"/archive/#{int_of_float(gettimeofday())}.mp3"
end
```
For simple functions like that, we have a simplified syntax that allows to
write them in a short way:
```
my_filename = {"/archive/#{int_of_float(gettimeofday())}.mp3"}
```
So, in your case, all you should have to do to make the filename dynamic in
your example is surround it with { }:
```
output.file(
%mp3,
{"/archive/#{int_of_float(gettimeofday())}.mp3"},
s,
reopen_when={0m}
)
```
If you want to read a more detailed presentation of the language and more,
I can recommend the liquidsoap book:
