This is a quick recipe for setting up CMake to use googletest in your projects.
First, make a tests
folder in the root of your project. Then, add
add_subdirectory(tests)
to your CMakeLists.txt
, after you’ve finished adding
the libraries in your project. Note that the way I’ve written this probably
requires CMake 3.4+.
A simple introduction to asyncio
This is a simple explanation of the asyncio
module and new supporting language
features in Python 3.5. Even though the new keywords async
and await
are new
language constructs, they are mostly1 useless without an event loop, and that
is supplied in the standard library as asyncio
. Also, you need awaitable
functions, which are only supplied by asyncio
(or in the growing set of async
libraries, like asyncssh
, quamash
etc.).
A little example of how asyncio works
This is a simple example to show how Asyncio works without using Asyncio itself, instead using a basic and poorly written event loop. This is only meant to give a flavor of what Asyncio does behind the curtains. I’m avoiding most details of the library design, like callbacks, just to keep this simple. Since this is written as an illustration, rather than real code, I’m going to dispense with trying to keep it 2.7 compatible.

I realized that CRY did not have a CMake based install option, so including it in a GEANT4 cmake project might not be obvious. This is how you would do it in your CMakeLists.txt:
[Read More]GTest Submodule
Note: There is a better way to do this described here.
If you’ve ever tried apt-get
or brew
to try to install gtest, you are
probably familiar with the fact that gtest is not “recommend” for global install
on your system. As an alternative, the recommendation is that you make it part
of your project. The process for making gtest part of your project, however, is
not well documented, at least for modern git projects. What follows is the
procedure I used to do so.
Slots in Python
Slots seem to be poorly documented. What they do is simple, but whether they are used is tricky. This is a little mini-post on slots.
