Hi,
I'm writing a module for dealing with video timing. The C++ code I'm using
as a basis uses gmtime to convert seconds into y:m:d.etc. Does anyone know
if this functionality is exposed in Julia anywhere?
I realise I could handle this myself with ccall, I just wanted to check to
see if I
Is there a way to do shift-enter to execute a cell using the iPad software
keyboard? Does shift enter just work on the hardware keyboard?
Those methods both work, and help me understand metaprogramming a little.
Thanks to you both.
I'm trying to use metaprogramming to create two functions. Each of which
includes a similar, long, call to run(). The calls are not quite identical.
Some flags have different arguments, and some are only present on one call.
I can't work out how to get expression interpolation to happen within

Perhaps it's a subtle attempt to incentivise more designers of mathematical

I have a little document which I add to periodically called "Julia
unsearchables" where I note down which things can't be found in the docs
without asking someone. I do hope, once my Thesis is done, that I can
contribute it to the documentation.
Hi,
I'm doing work reading image sequences using Images.jl. I haven't been able
to find in the docs for Images or FileIO a reference for how to load an
image into pre-allocated memory. Does such a thing exist?
Thanks
Andy
Agreed! A very clear introduction which shows off some of the power of
these new Array iterators.
Thanks, Tim.

Hi,
I'm trying to wrap a C library I've written. I want to use BinDeps to build
some source. The source is on our internal gitorious git server. A .tar.gz
of the code is available, but the URL to get that from just ends in the
branch name. So in my code I have

I have a csv with some data. One of the columns is something I'd always
like to be read as a string, although sometimes the value will just be
numerals. Is there some way to specify that I want this column to be an
AbstractString in readtable? Or perhaps some way to convert that column

I'm trying to follow the steps in the 0.4 Manual to create a custom

Hi,
I have some loops I'd like to observe/debug by seeing the parameters
change. In the REPL I can do
print(" $p1 $p2 \r")
flush(STDOUT)
and have my parameters updating on a line.
This doesn't seem to work in IJulia. When I try it, there is no output. I
guess this is because this isn't STDOUT,
Hi,
Please help me get started with this. Here' a simple Julia module, with an
attempt at documention:

This type defines a thing, which is a thing. Here's some code, declared by
indenting:

bee =

going wrong.

Thanks for your answer. I'm afraid your suggestions don't work. I've

I want to create a parametric type whose parameter is inferred from the
parameter of an argument. A toy example:
using Images
type TLPixel{T}
data::T
function TLPixel(img::Image{T})
new(img.data[1,1])
end
end
If I do this:
julia tlp = TLPixel{typeof(img.data[1,1])}(img)
Is there a way to create a parameterised type where the parameter describes
the number of items, ie
type Thing{N:Integer}
for i = 1:N
a_i::Float64
end
end
I realise one could achieve this simple example with an array, but I'm

I see. Yes, that fixed it. But I learned quite a bit about github and julia
in the meantime. :)
I've noted the fix in the github issue.

I'm hoping to play around with Geometric Moment Invariants, as (greyscale)
image feature descriptors. I get the impression that these might be part of
some stats package, but I'm coming at this from the machine vision side,
and so don't really know where to look. A few simple google searches
I'm believe I'm working in a relatively niche area, but I'm going to throw
my request in anyway :)
I often work with image sequences (from a still or video camera, but
nothing more exotic than broadcast cameras) which are to be displayed at
