I've been working on the same language for 3 years. I don't need to be neat to understand it.

I can post a properly spaced, annotated version if anyone is genuinely interested in how it works, though.

But can T4 templates choose the correct indefinite article (a/an) before nouns in your XML docs? I think not! :v:

Jokes aside, the nice thing about my pattern (albeit being longer than your template) is that it requires no math:

# Create a #region directive
\#region 4D swizzling\N

[%:c4+x;y;z;w] # Create a list of component names (X, Y, Z, W). Name it c4.


[r:4] # Repeat next block four times.
[s:\2,N] # Separate repetitions with two line breaks.
{
    (@x=[ri]) # Create a variable named x and set it to the current loop's iteration.
    
    [r:4] # Repeat next block four times.
    [s:\2,N] # Separate repetitions with two line breaks.
    {
        (@y=[ri]) # Create a variable named x equal to the current loop's iteration.
        
        [r:4] # Repeat next block four times.
        [s:\2,N] # Separate repetitions with two line breaks.
        {
            (@z=[ri]) # Create a variable named x equal to the current loop's iteration.
            
            [r:4] # Repeat next block four times.
            [s:\2,N] # Separate repetitions with two line breaks.
            {
                (@w=[ri]) Create a variable named w equal to the current loop's iteration.
                
                # Write an XML comment describing the components chosen for the current iteration.

Well, I just got into an awkward situation, I created a new project in VS 2013, however it did not create a solution along with it, which means that I can't create another project so that I can test my stuff, is there any way to add a solution to the project if that makes sense ?

I don't think it's possible to create a project without a solution.

It should look like this.

I made a small but useful thing for timing functions...

[cpp]/*
* scope_timer.hpp
*/

#pragma once

namespace timer {

class scope_timer {

private:

long long &m_ref;
long long m_init;

public:

static long long frequency();

long long elapsed_ticks() const;

scope_timer(long long &ref);
~scope_timer();

scope_timer(const scope_timer &copy) = delete;
scope_timer(scope_timer &&move) = delete;

};

}

/*
* scope_timer.cpp
*/

#include <Windows.h>
#include "scope_timer.hpp"

namespace timer {

long long scope_timer::frequency()
{
LARGE_INTEGER tmp;
QueryPerformanceFrequency(&tmp);
return tmp.QuadPart;
}

long long scope_timer::elapsed_ticks() const
{
LARGE_INTEGER tmp;
QueryPerformanceCounter(&tmp);
return tmp.QuadPart - m_init;
}

scope_timer::scope_timer(long long &ref) :
m_ref(ref), m_init(0)
{
m_init = elapsed_ticks();
}

scope_timer::~scope_timer()
{
InterlockedAdd64(&m_ref, elapsed_ticks());
}

}
[/cpp]

It just measures the time it takes from object construction to destruction, then atomically increments the initially supplied variable.

[Fleskhjerta]

Well, I managed to fix it, but for some reason now, when there is only one project, it "hides" the solution, and I have to manually go through the jungle of the menus to add a project until it shows me the solution.

Distinctly separate M/V/VM? Check!

Decent UX? Todo. Suggestions? Was originally using GroupBoxes instead of Expanders, but it got difficult to find the correct category and options.

I just learned about T4 the text template thing. That is really cool, I just wish that it had proper syntax and auto complete, maybe in 2015? Thankfully it seems like resharper has support so been using that.

Guises,

got Wednesday and Thursday off work. What do I work on?

I have like 0 personal projects going at the moment and have no idea what to work on.

I started working some shitty Java program where is would generate a RPGLE source file out of the information you pass to it, it makes my work life easier but it's a mess and I am procrastinating from cleaning it up.

I've been starting to make a space game since last week, 2000 lines in so far.
I've got text rendering and a "working" user interface system from scratch. (You'll see that proper kerning is on the bottom of my to-do list.)
The starry backdrop was generated using a program called LuaDraw I made a while ago, if anyone wants it I'll give the files. This is what the code for it looks like:

setCanvasSize(1024, 1024)
enableAntiAliasing(false)

--drawRect(0, 0, 1024, 1024, makeColor(0, 0, 0))
print("The black background is just for testing purposes.")
print("Comment out that line before saving it.")

for i = 1, 128 do
local starcolor = makeColorAlpha(math.random(255), 255, 255, 255)
drawPixel(math.random(1024), math.random(1024), starcolor)

They had a chance to implement a great macro system with T4, but they didn't. Now you just have this marginally useful thing that's always the last choice of a solution to any problem.

As I mentioned in a previous post I'm working on a new way to calculate the 3D strain and displacement fields in bone tissue from SR-CT scans. I was originally processing the data using 3rd party tools but I've decided to write a program to do it, so the whole thing can start with the raw CT data and get to the required end result without messing about with image processing programs or excel or anything.
