Actual Behavior

It appears the file attempts to launch, and then quits.

Need to implement a library loader

An alternative library loader is required, if we no-longer assume we have a sketchbook (or similar mac/windows) to install libraries. A central location (and vanilla processing compatible path is required).
It is thus proposed that libraries such as video and sound should live in eponymous folders in a libraries folder in the ~/.jruby_art folder. See fb3fe74 for first hack, works on linux with video library.

require 'jruby_art'

    @letters = (0...256).map do |i|
      LETTER_ORDER[map1d(i, (0...256), (0...LETTER_ORDER.length))]
    end
    # current brightness for each point

Issue with --watch

@tyfkda reported an issue with --watch latest version of gem to try:-
gem.zip

Currently Export to App is Not Supported

The original ruby-processing supported export of OS specific applications, it would seem saner to create a cross-platform exporter using say warbler.
@stevekinney, @fluxusfrequency, @poqudrof have you any experience?

issue with draw

Hi ,
for some reason when i excute my code i cant see the (@Head and @food as in the code ) but if i replace (height/2 and width/2 and rend(height) and rand(width)) with numbers it will work

def settings
  size 400, 400
end

def setup
  sketch_title 'snake'
  background 0
  stroke 255
  strokeWeight 2
  grid
  @head = Snake.new(width/2, height/2) # if i replace width/2 and height/2 with numbers like (..new(5,5)) it will work 
  @food = Food.new(rand(width), rand(height)) # if i replace rand(width) and rand(height) with numbers like (..new(5,5)) it will work 
  @up = false
  @down = false
  @lef = true
  @right = false
end

def draw
  @head.show
  @food.show
end

def grid
  (0..width).each do |x|

Installation Issue: Problem running sketches

Other

eg installation issue (just use this header and explain the problem as best you can)

I just recently installed jruby_art following the macOS instructions. However when I try and run an example I get an error message:

Running ./raining.rb...quit to run next sample
LoadError: load error: /usr/local/lib/ruby/gems/2.4.0/gems/jruby_art-1.2.9/lib/jruby_art/app -- java.lang.NoClassDefFoundError: processing/core/PApplet

Any idea what is causing the issue?

Processing Methods not found on Windows

I made simple test sketch.

def settings
  size 400, 400
  c = color rand 255
  red c
end

def setup
  sketch_title 'Test'
end

And when I ran it, um...

Which I assume means that the gem, or JRuby itself, couldn't find the red method? This also happens for a few other methods such as green, blue, colorMode, etc.

It's listed when I call find_method 'red' and I can run a sketch that doesn't call red such as loading an image or some such. And k9 --check returns fine for me. I don't quite know what's going on.

Error with loading data

Environment

k9 setup check:

Expected Behavior

The sketch should show the image with the histogram:

(But it happens with any sketch that requires depends on archives inside a data folder).

Actual Behavior

Every time I try to run any sketch file with stuff loading from the data folder a get this kind of error:

This has been giving me a headache for over 4 hours... I can't figure out what I'm doing wrong. I've goen through every guide at least 5 times and followed every instruction exactly...

Error loading data on macosx

@b-jufre has reported that the data path is not correctly interpreted on macosx. Until we find a more elegant fix for this problem you can get round it by providing an absolute path to the data folder in the sketch:-

# replace
loadImage('pic.png')
# with
loadImage('/path_to_sketch_folder/data/pic.png')

Or more elegantly and less volatile, use ruby to do it for us:-

loadImage(File.absolute_path('data/pic.png'))

This problem is expected to exist with shader sketches and basically any other sketch where data gets loaded from a local folder (using processing methods) does not affect sketches where we use ruby for io.

A possibly intermediate solution might be to override the processing dataPath method that is designed to to provide the absolute data path using java (seems to work OK on linux) but the processing/java form does not work on the mac (whereas the following does).

def data_path(pic)
   File.absolute_path("data/#{pic}")
end

But then you would need to use the data_path wrapper in your sketches.

loadImage(data_path('pic.png'))

Apart form the extra typing the advantage is there would be a mac specific fix, but such sketches should still work cross-platform. Furthermore it might obviate the need for the --nojruby flag (all-platforms?), proven to work in sketch on linux, with both shader and image sketches @tyfkda @poqudrof

Problems Running Test when building

Since ruby-2.7, there is a major incompatability issue with running tests (and psych stringio etc). Way round is not to use ruby-2.7...

Video and PDF libraries not working.

This is my result of k9 setup check:

Basically, many sketches won't run. All of those that use video libraries (I do have them installed in processing, and I've made copies of them in the sketch directory); and also others that use the processing libraries, like PDF. Examples:

issues with jdk12.02 on archlinux

The latest version of JRubyArt seems to work OK on linux mint, but not on Archlinux. Seems to be related to this issue:-
https://stackoverflow.com/questions/55847497/how-do-i-troubleshoot-inconsistency-detected-dl-lookup-c-111-java-result-12

Inconsistency detected by ld.so: dl-lookup.c: 111: check_match: Assertion `version->filename == NULL || ! _dl_name_match_p (version->filename, map)' failed!

I do not pretend to know what it means, but seems possibly a jogl issue or more likely glibc issue on Archlinux?

Issues with jdk9 with using inherited protected method

The most immediate problem is that JRuby can't access inherited protected methods (specifically runSketch) jruby/jruby#4851. Java 9 is much more restrictive concerning reflective access to non-public fields/methods, and @headius can't see a way of fixing it without making non-inherited java protected methods available. However there probably more issues to come and hit jruby before it hits us. For one example of offending code see line 67 library_loader.rb

 field = java.lang.Class.for_name('java.lang.ClassLoader').get_declared_field('sys_paths')
        if field
          field.accessible = true
          field.set(java.lang.Class.for_name('java.lang.System').get_class_loader, nil)
        end

Here is link to slated possible workaround http://mail.openjdk.java.net/pipermail/jigsaw-dev/2017-March/011763.html that will be banished by jdk10 (by then parrot will have fallen off perch or worse).

I also had this other error, which was before I did the k9 setup install :

Sketches not starting with Processing b3

Hello,

I recently moved to Processing 3, and it seems that JRubyArt is not working on my machine.

Here is the message : 

k9 run jwishy.rb 
LoadError: load error: /home/jiii/.rvm/gems/jruby-9.0.0.0.pre1/gems/jruby_art-0.4.2/lib/jruby_art/app -- java.lang.NoClassDefFoundError: processing/core/PApplet

jruby -v
jruby 9.0.0.0.pre1 (2.2.0p0) 2015-01-20 d537cab Java HotSpot(TM) 64-Bit Server VM 25.51-b03 on 1.8.0_51-b16 +jit [linux-amd64]

I have Processing 3.0b3, I tried with the one distributed on the website, and a custom build. Same error.
My version of JRuby is this from RVM :

jruby-9.0.0.0.pre1 [ x86_64 ]

Cheers,

The binaries for the video library for MacOS are in macosx64 folder

No one complained about this, but I'm not sure how or if native binaries got picked up because we'd falsely assumed all mac binaries were in the macosx folder. I'm in process of major refactor of library loader, however I'm looking at quick fix first see video branch.

Detect OS Error on Windows

Environment

K9_VERSION: JRubyArt version 1.5.0
OS: MINGW64_NT-10.0 DESKTOP-22BGKLK 2.8.0(0.309/5/3) 2017-05-19 13:17 x86_64 Msys

Expected Behavior

I'd like k9 to work.

Actual Behavior

RuntimeError: unsupported os: "mswin"
RuntimeError: unsupported os: "mswin32"
RuntimeError: unsupported os: "mswin64"

Problem

The person who wrote this didn't know how Regexp#match? works.

# Snippet from lib/jruby_art/config.rb
  class HostOS
    def self.os
      detect_os = RbConfig::CONFIG['host_os']
      case detect_os
      when /mac|darwin/ then :mac
      when /gnueabihf/ then :arm 
      when /linux/ then :linux
      when /solaris|bsd/ then :unix
      else
        WIN_PATTERNS.find { |reg| reg.match?(detect_os) } # <- issue here
        raise "unsupported os: #{detect_os.inspect}" if Regexp.last_match.nil? # <- this will never be true
        :windows
      end
    end
  end

In the Regexp documentation it says, Regexp#match? specifically checks for a match without updating relevant variables such as Regexp#last_match and $~. Therefore, you will always raise on windows unless you've use a match somewhere else in your codebase.

Solution

# Explicitly check for a match. Set to explicit false if none found.
windows = WIN_PATTERNS.detect(false) { |reg| reg.match?(detect_os) }
# Raise unless a match was found.
raise "unsupported os: #{detect_os.inspect}" unless windows
:windows

Does it Work?

I actually had to patch that myself to even get k9 -v to work in order to report my environment for this issue so, yeah. I didn't think something this small needed a PR, but I can do one if needed.

Cheers!
