using namespaces

[SergeVDev]

Hi all,

Is there in LESS something like using from C#/C++?

I have a library:

#sys
{
    .size()
    {
        …
    }
}

So, I want if there would be another library with a mixin .size() to be able to resolve the conflict, specifying #sys.size(), but I don't want writing #sys.size() just in case.

So, I'm looking for a way to add something like using #sys; at the top of a caller file.

Less does not have a direct equivalent to the using directive found in C#/C++ for importing namespaces. However, you can manage mixin name conflicts by using namespaces and calling the specific mixin with its namespace when needed. Unfortunately, you will need to specify the namespace each time you call the mixin to avoid conflicts, as Less does not support a global using directive to automatically resolve these conflicts.

For example, if you have a mixin defined in a namespace like this:

#sys {
  .size() {
    // mixin code
  }
}

You would call it using the namespace:

.element {
  #sys.size();
}

This approach ensures that you are explicitly using the correct mixin from the desired namespace, but it does require specifying the namespace each time you use the mixin ^[1].

hi @SergeVDev. I've been exploring adding something like Sass's @use (albeit with a little friendlier behavior and syntax). Because it's more of a module pattern, the file itself can act as the namespace and be imported into the current scope, yet wouldn't be automatically re-exported the way that @import works now.
