[julia-users] VideoIO failing to import in julia 0.4.6 (Fedora 24)

[Shivkumar Chandrasekaran]

On "import VideoIO" here is the relevant piece of the error:
ERROR: LoadError: LoadError: could not open file 
/home/shiv/.julia/v0.4/VideoIO/src/ffmpeg/AVUtil/src/../../../ffmpeg/AVUtil/v55/LIBAVUTIL.jl

The problem is that it is looking for "v55" directory but even github seems 
to have only "v54" directory.

Any idea how this can be fixed?

Thanks.

[julia-users] Maple's conformal plot of a complex function

[Shivkumar Chandrasekaran]

Before I re-invent the wheel, is there something similar to Maple's 
plot[conformal] for conformal plotting of a complex function in Julia? 
Here is the relevant Maple help page: 
http://www.maplesoft.com/support/help/Maple/view.aspx?path=plots%2fconformal

If not, what is the best/good starting point to implement it? Gadfly, 
Gaston, Cairo, ...?

Thanks.

Re: [julia-users] Specifying return type of a function

[Shivkumar Chandrasekaran]

Just documentation and readability of the functions themselves. For now I 
will just stick the return type in a comment (and hope I don't forget to 
change it if needed).

 But you shouldn't need to. Julia is able to find out what the return 
 type is as long as you write type-stable code. Can you give more details 
 about what you're trying to achieve?

  The complication in Julia is that with its multimethods, it is 
  not so 
  clear what the return type of a generic function actually 
  means.

[julia-users] Indenting by 2 spaces in ESS[Julia]

[Shivkumar Chandrasekaran]

I have tried all possible combinations of suggestions from the ESS manual 
to get the ESS[Julia] mode to convert indentation to 2 spaces rather than 4 
with no luck. Has anybody else succeeded, and if so could you please post 
your magic sauce? Thanks. --shiv--

Nuisance though.
