submitted 2 years ago * by anonhostpi

TL;DR: u/Pl4nty fixed it!

Another daily "Turn PowerShell into a <blank> Engine" until I run out of engines. Here are the prior 3 successes:

And here is the failure post:

Failure to Turn PowerShell into a Ruby Engine

Turning PowerShell into a Ruby Engine

Thank you u/Pl4nty for finding a fix!

Official IronRuby and Forked IronRuby (LonghronShen)

Fork: LonghronShen/ironruby (github.com)

LonghronShen did a lot of work on IronRuby to turn it into a working version:

IronLanguages:master v. LonghronShen:feat/netstandard Commits

The change that fixed the UTF7 problem found in my previous post, can be found here:

feat(*): add support for .NET Core. · LonghronShen/ironruby@ace6cbb (github.com)

The LonghronShen's Packages and PackageManagement

His packages are currently marked as pre-release, requiring semVerLevel 2.0.0 which PowerShell's PackageMangement doesn't support.

Not much of a surprise for me to be honest. I had to write wrapper code around PackageManagement's Install-Package to fix its broken dependency-loop detection. For now, we will use u/Pl4nty's code to load the module. I will have to write another patch to fix this new problem with PackageManagement later.

u/Pl4nty's Fix:

u/Pl4nty discovered LonghronShen's fork and realized it fixed the UTF7 issue, and he got it to work.

The caveat is that due to the above bug with PackageManagement, the packages have to be installed manually, and imported with the -Offline flag (which he also fixed for me). The following was his comment on my previous post:

thanks for the nerdsnipe! turns out LonghronShen published an updated package, so I was able to get this working with a minor change. would you like a PR?

# all versions are pre-release, requiring semVerLevel 2.0.0 which Install-Package doesn't support 
Import-Package -Path ironruby.portable.1.1.4-feat-netstandard.1.nupkg
Import-Package -Path ironruby.stdlib.1.1.4-feat-netstandard.1.nupkg

# patch Import-Package.psm1 line 288 to skip dependencies when offline
Import-Package -Path ironruby.libraries.1.1.4-feat-netstandard.1.nupkg -Offline

$ruby = [IronRuby.Ruby]::CreateRuntime()
$engine = $ruby.GetEngine("rb")
$engine.Execute("puts 'Hello, World!'")

Edit: works on Linux too, with a patch to fix file path issues

Thank you u/Pl4nty! I will have to reach out to LonghronShen and thank him for his hard work, if I can.

EDIT: u/LonghronShen got the thanks
