Hi,
I'm returning to Julia after a long break (a year?) and am trying to get
some old code I had lying around compiling.
When I try to run tests for https://github.com/andrewcooke/IntModN.jl (at
4bc2734b80a15108ff66fd61705681e9d50a94c1) I see the error:

Well, this all works fine with 0.3, so I'm going to chalk this up to
weirdness in git trunk 0.4 (the above was with git as of an hour or so
before posting).

Does anyone have a working example that calls printf via llvmcall?
I realise I'm uncomfortably inbetween llvmdev and julia-users, but I'm
asking here first because I suspect my limitations are still more
julia-related.

explicit) and I am wondering whether I can support both in a single code

Is there a simple way, in 0.4, given the type of a tuple, to know how many
entries it has?
When types of tuples were themselves tuples you could just use length, but
that no longer works.

There's a new parser library for Julia 0.3 and 0.4 -
https://github.com/andrewcooke/SimpleParser.jl
It's got some rough edges that I hope to clean up in the next week or so,
with a first release probably next weekend.
Bug reports welcome.

Is there any way to switch the "visible" type - the thing that is
dispatched on - at runtime?
For example, you might think that a Union() could do this, but the
"visible" type is either always be the Union, and not either of the
subtypes, or doesn't allow the value to be changed.

i really wanted something that took *only* the contents of the array, while
getindex has the type too. so i've defined my own "array" function:
array(T) = (builder(x...) = T[x...])
which i can use as, say, array(Any).

you can compare the generated code yourself -
http://blog.leahhanson.us/julia-introspects.html
no real idea why it would be faster myself. the immutable is passed by
value, so you're still pushing data to the stack. would have guessed it to
be the same, but am no expert.

i've worried about something similar, but on a different scale - some kind
of pipeline for processing (image) data, where you have a series of
commands that produce intermediate images and you might go back over the
commands and edit some parameter, then request that necessary work is
re-compu
one option might be to define both with- and without-keywords versions and
then call the without from the with:
f(x; t) = f(x, t)
f(x::Int, t::Int) = ...
f(x::Number, t::Number) = ...
but you may need some logic to set default values (zero() and one() may be
useful).

it seems to me that coroutines (Tasks) in julia are very much intended for

actually it being a subtype of integer is irrelevant here, since that field
is untyped.

ah! thank-you. i had no idea about that.
is there any kind of isbits container? will a tuple work?
thanks again,

sure, i understand the reasoning, i just didn't know it was actually
implemented / verified in any way. rewriting the code now... cheers,

i suspect that's by accident rather than design. it also fails on trunk
with the error:
ERROR: syntax: "counter=0" inside type definition is reserved

bits types, and nested tuples, you can
encode pretty much any value in "s-expressions" of tuples, where the first
value is a data type and subsequent values are arguments.

This may have arisen from a call to the constructor Tuple{Int64}(...),
since type constructors fall back to convert methods.

if it doesn't affect you that's great! means it would mean it's easy to
change without worrying you...

hi, seth contacted me to see whether my ParserCombinator library could do

which was all I found in the source on a first look).

you may be interested in https://github.com/andrewcooke/AutoHashEquals.jl,
but it uses all entries. i will consider adding that feature, though (with
the idea that if it's not used at all, all are used).
