mwotton / hubris Goto Github PK

Many files have permissions of rw for the root user and group, but no permissions for others, for example

-rw-rw---- 1 root root 175 2009-09-07 20:41 Hubris.rb

Temporary fix seems to be http://www.arthaey.com/tech/support/#Ruby0

Replication:

irb(main):001:0> require "rubygems"

irb(main):002:0> require "Hubris"

When using:

 hubris :source => "MyModule.hs"

Modifications to the Haskell file after it has been compiled once do not trigger recompiles.

waiting for BigInts in jhc...

it'd be good to have some examples with benchmarks, hopefully showing an improvement.

Ability to call multi-argument functions from the Ruby side. Requiring all arguments in Ruby-land would be acceptable if it's easier at first IMO.

currently, Hubris needs to know where the ruby headers are when it's installed. this is pretty awkward, and makes it harder to install. It should be possible to defer this to the time that the Hubrify binary is actually run: that way, the running ruby process can pass the configuration information on the command line. Same goes for libruby.so

find out how to import functions involving doubles + floats. currently failing on JHC

This may be a problem at my end, but does this package in particular use graphviz's dot, or is that something most ruby packages use?

(googling suggests that dot is a binary belonging to the graphviz diagram drawing tool)

the README install notes say to pull down 6.12.1-rc2. 6.12.1 is on the website now. http://www.haskell.org/ghc/dist/6.12.1/.

It would be nice to also have a mode for binding to binaries on a system where GHC is not present. I may look into this if I get some time.

as of 0.0.1, all steps are manual. It would be better if Hubris made some attempt to map ruby data structures into something haskell-friendly, and vice versa.

also, it should be possible to inline haskell code a la RubyInline or Inline::C in Perl.

if we've already built the dylib, we shouldn't need to build it again.
maybe see how RubyInline does it.

CArray & Bytestring support required - how do we build these libs?

Hubris seems to be passing all of its specs except for the concurrency one. Sometimes it gives a segmentation fault, sometimes it gives a no method exception.

Gist is at http://gist.github.com/217878

currently Hubris only works with JHC because GHC cannot build dynamic libraries. When GHC's capabilities change, add a backend for it.

Hi,

Could you point to a simple example of passing in a Ruby hash?

Thanks.

the mapping layer to libruby is a bit broken.

/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- open4 (LoadError)

This was fixed when I gem installed open4.

I received this same failure when I tried to install.

May be my fault, but I'm mentioning it anyway.

When installing the gem on Ubuntu, using root gem i hubris, the Hubris code attempts to create /var/hubris, but regular users may not have permission to do this.

Code in lib/hubris.rb wants this:

SO_CACHE = File.expand_path("/var/hubris/cache")

HS_CACHE = File.expand_path("/var/hubris/source")

and then calls FileUtils.mkdir_p for each.
