digitalmars.D.learn - ctfe append too slow, but can't speed up

reply Jethro <qyzz gr.ff> writes:
ctfe string appending is way to slow, I have tried the suggested 
methods and nothing works and slows down by at least an order of 
magnitude.

I need a drop in replacement(no other changes) that can take over 
the duties of string and allow for memory reuse.

reserve, cpacity, assumeSafeAppend cannot be used by ctfe so are 
useless.

I've tried to shadow a pre-allocated buffer but that doens't work 
either.

There is no memory reuse in CTFE right now, that's why the engine is being rewritten... I'd suggest writing a regular runtime program to output the code while you wait for the new ctfe engine to be released.

You can give me your code, and I'll see what has to be done to run it with newCTFE.
