Written with C and Windows API and utilizes existing Windows facilities, resulting in very slim code.

Executable and DLL are very small (<20KB total)

Make sure you place the DLL next to the executable, so it can find it.

After building, run the executable lightwm.exe which will reside in the release and/or debug folder, depending on what you built.

Upon running, it will immediately tile all the non-minimized windows on your screen.

The program will run in the background. To quit LightWM, use alt+q.

You can use alt+j and alt+k to go to the next/previous window with your keyboard.

You can use alt+f hotkey to toggle fullscreen mode which will disable tiling and put the focused window in fullscreen, pressing alt+f again will enable tiling again and tile all non-minimized windows

You can use alt+1 up until alt+9 to go to workspace number 1 until 9 respectively

You can build using the "x64 Native Tools Command Prompt for VS 2022" that comes with Microsoft Visual Studio Build Tools:

In the console you can run nmake to build according to the Makefile

nmake

I haven't tried building with a different VS version or building x86, but that may work as well.

One of my main goals with this project is to keep it as minimal as possible, for example I decidd against using a dynamic configuration on purpose.

Thus, make sure to keep the contributions as simple as possible.

If you plan on adding a completely new feature, let's discuss it on the issues beforehand.

Also notice that this project does not use any C library functions on purpose, only Windows API. This keeps everything as minimal as possible.

Functions and variables should be in camelCase

In general comments should be avoided unless they are absolutely necessary

Avoid adding obvious comments on the code like:

// Prints hello on the screen
printf("Hello!\n");

Avoid comments explaining the logic in other words:

// Allocate memory for the string and for the null terminator
malloc(1024 + 1);

Instead something like this is much better:

const int nullTermSize = 1;
malloc(strlen(path) + nullTermSize);

Example of when a comment is necessary and has added value:

// This DLL is loaded into many processes on the computer, therefore we need to keep the logic here as simple as possible to avoid slowing down the system

int* and not int *

Opening braces { in the same line as the block definition

if (cond) {
}

and not:

if (cond)
{
}

Opening braces { in a new line after the function definition

void init()
{
}

and not:

void init() {
}

Space between the block name and the brackets

if (statement) and not if(statement)
