in thread Push style templating systems

Thanks for clearing that up, at least somewhat ;-)

Citing Terence Parr
The trick is to provide sufficient power in a template engine without providing constructs that allow separation violation.

It is my understanding that he shows that "push" (his Definition 8) is sufficiently strict to ensure separation. But for the template engine user's convenience you can add things while separation is still enforced.

He designed StringTemplate accordingly, but StringTemplate isn't pure-push then, isn't it?

    I don't know what pure push is. If I had to guess, I would say that the 5 rules implied by strict separation, listed after Definition 7, define pure push. And as far as I can see, StringTemplate doesnt break any of those rules.

    I know Seamstress doesnt.

[shmem]: Discipulus: has that been in the CB? or in a PM node proper? for the latter case, can you provide the ID?
[Discipulus]: you seriously can use their in this way in eng?
[Corion]: Meh. $effin_bad_system has an interface breakdown and then loads events in parallel with events overtaking one another instead of being processed sequentially
[shmem]: Discipulus: dunno, but we do all the time ^^
[choroba]: Discipulus I was taught so by a Londoner
[shmem]: Corion: very clear case of missing sequence number
[Corion]: shmem: Yeah. I guess they have a sequence number but distribute the events across threads or machines or whatever.
[karlgoethebier]: choroba: another chapter of "Learning English At The Monastry"?
[shmem]: Corion, well then... next issue, sequence number not a shared resource :P
[Discipulus]: shmem i'm searching it.. but failing i was sure was in Re: Let's Make PerlMonks Great Again! -- suggestions and dreams
