what is this "double gemhead idiom?? i see it in a patch but what does it mean in practice?? this patch looks quite strange

I think, I explained it a bit before, so you also may want to search the list archive. The basic idea is to use two gemheads, where one (the lower) is put into forced rendering mode, which means, that it's switched off as default and is made to render only every time, it receives a bang. The upper gemhead is used as a kind of metro, which bangs the lower gemhead on every frame. The trick then is to bang the lower gemhead multiple times on every frame and change some data in the meantime.

Please see attached patch for another example.

thanks for the answer now i get it

the idea seems very similar to using the [repeat] object do you think that using doubled gemhead has any advantages over using
repeat?? is there any difference in practice?

since i have never heard of using double gemhead before i am just wondering if i could do any new things with this approach

in general not in the particular case of displaying text

thx.
