Re: [julia-users] Help with eval-free macro
Sorry to revive this old thread, but I am trying to understand macros, so
please bear with me:
When I try to use this example , replacing expr by Expr so the macro
becomes:
macro dict(syms...)
Expr(:dict, { :($(Expr(:quote,s))=$(esc(s))) for s in syms })
end
When I now ask for julia r = @dict(a,b)
I get ERROR: syntax: malformed expression
Also this version:
macro dict(syms...)
Expr(:dict, { :($(string(s))=$(esc(s))) for s in syms })
end
doesn't work for me either; it gives the same error.
Could someone please explain to me why the expression returned by the macro
is malformed?
This is on Julia 0.3 Windows 8 64bit.
Thanks very much!

May I propose adding this somewhere at the end of the manual section on

before one ventures out into the cold world of trial and error ;-)
Just for reference, I modified the macro slightly to use the actual names
instead of the symbols as the keys:

expr(:dict, { :($(string(s))=$(esc(s))) for s in syms })

javascript::
This does it:

The approach I used, which is generally effective for writing macros is
to create an example of the expression I want the macro to construct and
then write code to build that:
julia ex = :([:a = hello, :b = world])
:($(expr(:dict, :(:a=hello), :(:b=world
julia ex.head
:dict
julia ex.args
2-element Any Array:
:(:a=hello)
:(:b=world)
So I want an Expr object whose head is :dict and whose args is an array
of expression of the form :(:sym = value). The tricky bits are:
• Wrapping s in expr(:quote,s) so that it ends up in the final
AST as an expression for a symbol rather than splicing the symbol directly
in since that would be as if you'd written the variable rather than the
symbol for it.
• Wrapping the s in esc(s) so that it is evaluated in the macro
caller's context, not the macro definition context. Note that this isn't a
concern for expr(:quote,s) because symbols are the same in any context.
Hope that helps.

Re: [julia-users] Re: ambiguous +(...) definitions between Images and DataArrays
Unfortunately, there isn't a simple fix. Someone just has to knuckle down and
fix this in julia itself. Until then, tolerate the ambiguity warnings (if they
aren't actually relevant for operations you want to perform), or work around
then by writing glue code.

[julia-users] Re: windows 7: cutpaste, window widthposition, etc
The first three questions aren't related to Julia REPL specifically. On Windows when you launch Julia it runs in a command prompt window, so all the normal command prompt stuff applies: you change setting by going to Properties in the drop down menu of the icon in the upper right, and you copy by going into mark mode (via right-click) and select something and click enter. Colors I don't know how to change but I agree they are terrible.

Re: [julia-users] Re: windows 7: cutpaste, window widthposition, etc
The display of Julia REPL colors is controlled by the settings of the terminal; Julia says this text is blue and the terminal/command prompt decides what that means. I know you can change the terminal color preferences on Linux; I don't know how to do that on Windows. -- Leah On Tue, Sep 23, 2014 at 8:38 AM, Johan Sigfrids johan.sigfr...@gmail.com wrote: The first three questions aren't related to Julia REPL specifically.

Re: [julia-users] Re: Article on `@simd`
Based on this thread, I spent a few days playing around with a toy algorithm in Julia and C++ (trying OpenLC OpenMP), and finally ISPC. My verdict? ISPC is nothing short of magical. While my code was easily parallelizable (working independently on each element of a large array), it was not readily vectorizable by the usual suspects (LLVM or g++) due to potential branch divergence. The inner loop contains several if statements and even a while loop. In practice, these branches are almost never taken, but their presence seems to sufficiently discourage vectorizers such that they don't attempt a transformation. On my machine, a reasonably optimized C++/gcc 5.0 runs through a 440MB computation in about 380ms. (Julia's not far behind). Taking the inner loop functions and compiling them in ispc was almost entirely a copy/paste exercise. Some thought was required but far less than other approaches. My 8-wide AVX-enabled Intel CPU now runs the same benchmark in 140ms, or 2.7 times faster. I'm not a vector wizard, so perhaps it's possible to get much closer to the theoretical 8x speedup, but for minimal effort, unlocking the 2.7x left otherwise idle in the processor seems like a tremendous thing. Implementing something ispc-like as Julia macros would not be simple. It's sufficiently different than scalar code so as to require a different type system, differentiating between values which are inherently vectors (varying) and those which remain scalar (uniform). It has some new constructs (foreach, foreach_tiled, etc.). If you want to take explicit advantage of the vectorized code, then there are a large family of functions which give access to typical vector instructions (shuffle, rotate, scatter, etc.) I think if you want scalar code to be automatically vectorized, then you just have to wait for state of the art to improve in LLVM. But if you're willing to to make what are often minor changes to your loop, I suspect Julia could help with a properly designed macro that applied ISPC-like transformations. It would be extremely powerful, but also expensive to build. This hypothetical cleverer @simd vector would be a very large compiler unto itself.

I think they are up to something clever. If I read things correctly: ispc adds new keywords that describes the memory layout (!) of data structures that are accessed via SIMD instructions. There exist a few commonly-used data layout optimizations that are generally necessary to achieve good performance with SIMD code, called SOA or replicated or similar. Apparently, ispc introduces respective keywords that automatically transform the layout of data data structures. I wonder whether something equivalent could be implemented via macros in Julia. These would be macros acting on type declarations, not on code. Presumably, these would be array- or structure-like data types, and accessing them is then slightly more complex, so that one would also need to automatically define respective iterators. Maybe there could be a companion macro that acts on loops, so that the loops are transformed (and simd'ized) the same way as the data types... -erik -- Erik Schnetter schn...@cct.lsu.edu javascript: http://www.perimeterinstitute.ca/personal/eschnetter/
Re: [julia-users] Help needed with creating Julia package
Sorry for the delay, but I have now added a function to flint which takes the location of the CPimport.txt file (which is in the flint source tree in the qadic directory) at runtime. The function is void flint_set_cpimport(char * path); where path is a full path including filename of the (CPimport.txt) file. This is now committed to the flint trunk branch in my github. We should be able to use this by calling it from Julia when initialising anything that requires Conway polynomials. I haven't made the necessary changes to Nemo yet, but most of Nemo works without the changes since only the finite field functionality actually use Conway polynomials. This should allow us to move forward with a binary version of Nemo on Windows, as soon as we decide a good place to install the CPimport.txt file. I guess it could just sit in the Nemo directory and just be made part of the Nemo git checkout. Bill. On Monday, 15 September 2014 14:45:01 UTC+2, Tony Kelman wrote: I think this is very common. But it means that people who really want their code to actually compile on Windows frequently have an inferior system with which to do it, because all the real hackers are cross compiling from Linux. Or Cygwin. Part of the point is the exact same process should result in the same built binaries for cross-compilation from Linux or cross-compilation from Cygwin. Any complaint about Cygwin in terms of size or performance applies equally to MSYS2, and MSYS2's newness and multitude of build/run modes causes more trouble than it's worth in many cases. or provide Visual Studio project files Can you blame them? Speaking of awful, impenetrable build systems that don't translate well to other platforms... MPIR and GMP are *incredibly* complex projects and few people recognise the subtleties which simply don't arise for other types of software. I'm not familiar with writing this type of software, but plenty familiar with building it, and I really don't see a whole lot that goes into a bignum library that doesn't also happen in, say, an optimized BLAS/LAPACK implementation. Of course those are also notorious for having messy and fragile build systems.

using PyPlot
But I don’t want to repeat this code whenever I start a julia session. Can
you please help me to fix this permanently?
I’m working with the julia version 0.4.0-dev+728, and matplotlib version:

[julia-users] tags not showing up on package master branch
This may be a julia (Pkg) question or a plain old git question (if so, sorry). Pkg.checkout(Gtk) Then from the Gtk.jl directory, git log --oneline --decorate shows v0.7.1 as the last tag, which occurred on July 21. Since there have been many commits since then, I thought it was time to tag a new version. But I got a 0.7.2 already exists error. After poking around a while, I did Pkg.free(Gtk) at which point git log --oneline --decorate shows the same commit history, but more tags, up to and including v0.7.4 on Sept 17 (rather more recent). Any idea why the tags aren't included in master? --Tim

[julia-users] Re: windows 7: cutpaste, window widthposition, etc
We hope to eventually bundle Windows Julia with mintty, a much nicer terminal experience (used by Cygwin and MSYS2) than the default console in Windows. You can run Julia inside mintty right now, but if you are using Cygwin or MSYS2 there are some issues with the package manager not working with the Cygwin/MSYS2 version of git. This problem should get fixed by switching from command-line git to libgit2, but that is stalled waiting for the author of the bindings to respond and look at it.

Great.

Re: [julia-users] Re: Article on `@simd`
Update on 64-bit support for vectorizing loops: The support just went into the Github sources. See https://github.com/JuliaLang/julia/pull/8452 . Though for 3D vectors, those are in need of tuple vectorization. See https://github.com/JuliaLang/julia/pull/6271 for the prototype. Unfortunately the prototyped slowed down compilation too much to be enabled by default. But it's possible we might evolve a way to turn it on for specially marked regions of code, or speed up how fast it can reject uninteresting code.

[julia-users] Pretty Printing of Results

Can anyone provide a workable solution to this issue? Is there a general purpose function where a user could input the variables names and matrix of data to be printed? Any help that could be provided would be greatly appreciated. Also, if anyone is interested in these models, please let me know. I'd like to eventually release these for all to use after this issue is surmounted. Regards, Don

[julia-users] Re: Pretty Printing of Results
Donald, I would enjoy seeing your code once you release it. I'm doing research with Bayesian bioinformatics models using MCMC. You can place all your MCMC samples in a DataFrame and then call describe on it to get a very similar output to what you described. You can also write your own inspired from the definition https://github.com/JuliaStats/DataFrames.jl/blob/cb9cd7f4c72eb49efd94d722731919a4086f683c/src/dataframe/dataframe.jl#L683 of the describe function. Or instead of using rpad to get the spacing right, you can use @printf or @sprintf instead.

Any help that could be provided would be greatly appreciated. Also, if anyone is interested in these models, please let me know. I'd like to eventually release these for all to use after this issue is surmounted. Regards, Don

a=@data([NA,3,5,7,NA,3,7]) i want to do this: b=[NA,a[1:end-1]] but julia says no convert methods. is there anyone know some other ways?
