CSS-Purge didn't do anything to my test file

[bartkusa]

I couldn't find any examples of what CSS-Purge does, so I don't know what to expect from it. I tried it out with this input file:

.test {
    color: red;
    color: blue;
    font-weight: bold;
}
.test2 {
    color: green;
}
.test2 {
    color: green;
    color: green;
}
.test {
    color: purple;
}
.invalidProperties {
    invalid:property;
}

I expected the output to be:

.test {
    font-weight: bold;
}
.test2 {
    color: green;
}
.test {
    color: purple;
}
.invalidProperties {
    invalid:property;
}

Instead, this is what CSS-Purge actually output:

.test {
    color: red;
    color: blue;
    font-weight: bold;
}
.test2 {
    color: green;
}
.test2 {
    color: green;
    color: green;
}
.test {
    color: purple;
}
.invalidProperties {
    invalid: property;
}

What should I have expected? What kinds of redundancies and duplicates is CSS-Purge supposed to find?

+1 => I don't understand, it only removes some spaces, no redundancies.

So I just tested with:

css-purge -i test.css -o test_o.css

test.css

.test {
    color: red;
    color: blue;
    font-weight: bold;
}
.test2 {
    color: green;
}
.test2 {
    color: green;
    color: green;
}
.test {
    color: purple;
}
.invalidProperties {
    invalid:property;
}

and got:

test_o.css

.test {
    color: purple;
    color: purple;
    font-weight: bold;
}
.test2 {
    color: green;
}
.invalidProperties {
    invalid: property;
}

I'm thinking for the duplicate property with different values of either retaining all the variations or using just the last one, which one sounds better?

[AndrewEQ]

Did you install it globally? npm install css-purge -g

Ok, I was able to replicate the issue, I'm thinking that its a dependency issue, will investigate and let y'all know...

[AndrewEQ]

Sorted, it was just the dependencies, thanks for reporting it in, I'll look into a dependency overhaul soon.

Resolved the duplicate rule properties.
