Hello,

I can’t call the object’s method, thought it exists.

My ruby script:

* * *

# Let’s dump .Net methods

far.get\_type.get\_methods.each { |m| p m.name }

# Try to call ‘RegisterTool’ method

begin  
far.register\_tool  
rescue =\> err  
p err  
end

begin  
far.RegisterTool  
rescue =\> err  
p err  
end

* * *

I get such output:

* * *

…  
“RegisterFiler”  
“RegisterTool”  
…

#\<NoMethodError: undefined method `register_tool' for #<FarNet::Far:0x000005c>> #<NoMethodError: undefined method`RegisterTool’ for  
#FarNet::Far:0x000005c\>

* * *

Not sure if this matters, but ‘far’ variable is set by the script host  
scope.SetVariable(“far”, Far);

Thanks,

- Alex

Could you sent source code for FarNet class (RegisterTool method  
declaration)?

Probably this is some how related to

Btw, IronPython can call same method:

[http://farnet.googlecode.com/files/IronPythonFar.1.0.35.rar](http://farnet.googlecode.com/files/IronPythonFar.1.0.35.rar)  
IronPythonFar\Scripts\calc.py

* * *

far.RegisterTool(ipy, “IronPython calculator”, calc,  
FarManager.ToolOptions.F11Menus)

* * *
