QUESTION
I have a large WPF application with many solutions and each solution has many projects. IronRuby (v1.0.4) script is used to compile all the projects in order.
Problem Statement:
IronRuby script fails to compile projects which use 'nameof' operator with the following error:
ANSWER
Answered 2019-Sep-11 at 22:10There is a compile.rb class which my build (ruby) script was pointing to, this class had hardcoded version to look for VS2015, if that version is not found, then script would use v4.0 build which is why I would always see v4.0 when I had VS above 2015.
QUESTION
IronRuby and IronPython have custom built-ins, standard modules and you can write code straight out of hand(Directly using statements and declarations in the code), instead of using namespaces and classes like in C# and VB.NET.
I am trying to use CodeCompileUnit, but I can only find Namespaces
, AssemblyCustomAttributes
, StartDirectives
, EndDirectives
and ReferencedAssemblies
properties. No other stuff, not even classes(you can put classes without namespaces in C# and VB.NET).
I am trying to find a way to be able to add stuff like variable declaration, methods and expressions to the CodeCompileUnit instead of namespaces and directives only.
How can I achieve this?
...ANSWER
Answered 2019-May-10 at 08:17System.CodeDOM
is a code generation system that has been built to target language features that are common to many .NET languages, in particular C# and VB.NET. It has not been designed to support specialities of any .NET language.
Even though you may be allowed to put statements as top-level entities in IronPython or IronRuby, you are not allowed to do so in C# or VB.NET and therefore, this is not supported by System.CodeDOM.
Note that also the development of System.CodeDOM
essentially stopped after .NET 2.0. Therefore, this code model does not support more recent syntax features of C# or VB.NET as well, such as expressions-syntax, lambda expressions or async/await. From my impression, System.CodeDOM
was primarily invented to make things like the WinForms designer possible. In applications like this, it is not really important to have all language features of all languages covered, but only to have the commonalities covered such that you can generate the same code in multiple languages simulataneously. Because all .NET languages must support the CLI, the commonalities also include things like events that are somewhat specific (e.g. Java does not know them).
Edit: And therefore, do not expect that System.CodeDOM
covers all language features of all languages, expect it only to support enough of all languages to generate code for it.
QUESTION
I have been following "How-to: Use Cucumber with .NET and C# under IronRuby" to set up Cucumber for .net on Windows. I had no problem installing Ruby, IronRuby and installing Cucumber, but when I came to this step, my troubles started:
Check to see if Cucumber under IronRuby works:
icucumber –help
Here icucumber.bat
is a file we write to tell IronRuby where to find gems. I just copied the script from the link above and changed the directories to match my installation directories.
I first got a bunch of require
errors, which I fixed by installing Cucumber (0.6.4) according to "IRONRUBY: 0 TO CUCUMBER IN 15 MINUTES":
IronRuby isn’t quite ready for the latest version of Cucumber.
I also installed term-ansicolor
by doing gem install term-ansicolor
. At this point, although I got rid of the require
errors, I got a new one:
ANSWER
Answered 2017-May-24 at 19:17It seems that IronRuby isn't ready for the last version of term-ansicolor
either. Around Ruby 2.0 it became possible to use keyword parameters (the max: 255
part in your error message) but since version 1.9 this can be simulated using hashes.
The last release of IronRuby I can find is 1.1.3 and it claims to be working towards compatibility with Ruby 1.9 but it seems kind of abandoned. So you can downgrade your gems even further or change your Ruby implementation to MRI or JRuby.
QUESTION
Using Ubuntu 14.04. I'm trying to upgrade to Ruby 2.3.3 from 2.0.0. The installation seemed to go fine, but when I start a new terminal, it refuses to use 2.3.3.
I've tried numerous fixes, but after each of them, restarting my terminal and running ruby -v
returns "ruby 2.0.0p648 (2015-12-16 revision 53162) [x86_64-linux]
".
I tried running rvm --default use ruby-2.3.3
, which makes my terminal use 2.3.3, but when I restart the terminal it reverts back to 2.0.0.
I tried running rvm reset
, which doesn't do anything and returns the following error message:

Install ironruby
On a UNIX-like operating system, using your system’s package manager is easiest. However, the packaged Ruby version may not be the newest one. There is also an installer for Windows. Managers help you to switch between multiple Ruby versions on your system. Installers can be used to install a specific or multiple Ruby versions. Please refer ruby-lang.org for more information.
