While installing my small package, I met a tricky problem. For clarity, let me explain it with the following simplified example. In ~/pkg/R/aclass.R, setClass("aclass", contains="bclass", representation(i="numeric")) In ~/pkg/R/bclass.R, setClass("bclass", representation(j="numeric")) After building a "pkg" package, the file pkg.R in R directory has: setClass("acl...

Dear all, I am having problem to create a package when this package is supposed to have some newly created s4 class. Here is my workout: > #rm(list = ls()) > setClass("aClass", sealed=T, representation(slot1 = "vector", slot2 = "character")) [1] "aClass" > fn1 <- function(x, y, z) { + x <- x[1] + y <- y[1] + z <- as.character(z[1]) + new("aClass", slot1 = x+y, slot2 = z) + } > #fn1(1,2,3) > package.skele...

Hello ! I posted a simple template to show how to add ''act_as_whatever'' to ActiveRecord. I think this might be useful to others as there are some trickery ruby things in this file. Here is the template : http://textsnippets.com/posts/show/384 Gaspard Bucher -- Posted via http://www.ruby-forum.com/.

Hello all. I''m writing my own object using prototype and I wonder how you write and call only one instance of class. Can anyone share his idea of singleton? thanks Gregor ---------------------------------------------------- Gdy nadchodzi przełomowy moment w historii, musisz zdecydować, po czyjej stronie będziesz.

I wonder if you can have more than one has_many :through association between 2 models. For example... I have a model Teacher and a model Class Now, 1 Teacher works in many Classes, right?. So I need a join model like class Work < ActiveRecord::Base belongs_to :teacher belongs_to :class end But I also would like to know if a teacher CAN teach a class before I

I''m trying to specify that a particular view must render two different partials. My spec looks like: describe AClass do it do template.should_receive(:render).with(:partial => ''foo'', :locals => { ... }) ... end describe ''some conditional case'' do it do template.should_receive(:render).with(:partial => ''bar'', :locals =&g...

As long as the functions' arguments an return types are simple enough, it seems doable. But have you something in mind for cases such as AClass foo(SomeOtherClass other); ? -- Óscar

...nction that longjmps, they will not be executed correctly (however, catch blocks and dtors higher up in the stack will). This may be fixed sometime after the 1.0 release, but it is not super high priority. In particular, this testcase works: void jmp() { longjmp(...); } void test() { try { AClass A; // A's dtor is called due to longjmp jmp(); // not reached } catch (...) {} // eat the longjmp "exception" } but this does not: void test() { try { AClass A; // A's dtor is NOT called due to longjmp longjmp(...); // not reached } catch (...) {} //...

Hi, The question about the name mangling gave me an idea that it can be used to automate registration of DLL functions. Instead of manually creating Function objects specifying a return type and argument types which is error-prone and time-consuming one can get a list of functions exported from a DLL using Windows API, demangle each name and construct a Function object from it. Is there any
