I was doing some benchmarking on a base64-encoding routine and was
hoping to change it from the form:
ptr = malloc(large-enough)
for all data
base64-decode
into
init luaL_buffer
for all data
if not enough buffer left, luaL_addsize and get new ptr
base64-decode
It turns out that this isn't so nice, particularly when the data size
is much larger than LUAL_BUFFERSIZE (on order of 10s of MB)
Has there been any thought on how one could create an arbitrary string-
region that one could write to and then finalize?
Perhaps even be able to convert a userdata object into a string in
place (and freeing it if the string value already existed due to
interning)
Another feature that would probably be useful (particularly for string-
building) is for userdata to be resizeable...
Any thoughts?
