Could that function just be called `string`? The current behaviour of string applied to an IOBuffer does not seem useful: julia> i = IOBuffer() IOBuffer(data=Uint8[...], readable=true, writable=true, seekable=true, append=false, size=0, maxsize=Inf, ptr=1, mark=-1) julia> string(i) "IOBuffer(data=Uint8[...], readable=true, writable=true, seekable=true, append=false, size=0, maxsize=Inf, ptr=1, mark=-1)" > > On Tue, Feb 17, 2015 at 9:06 AM, Maurice Diamantini < > maurice.d...@gmail.com <javascript:>> wrote: > >> Hi, >> >> In Ruby, String is mutable which allows to build large strings like this: >> txt = "" >> for ... >> txt << "yet another line\n" >> end >> # do something with txt >> >> The Julia the (bad) way I use is to do: >> txt = "" >> for ... >> txt *= "yet another line\n" >> end >> # do something with txt >> >> Which is very slow for a big string (because it build a new more and more >> string at each iteration). >> >> So is there another way to do it (in standard Julia)? >> Or is there another type which could be used (something like a Buffer >> type or Array type)? >> >> Thank, >> -- Maurice >> > >
