怎么用dlang语言实现laravel的IlluminateSupportStr以下几个方法我好在d语言的工程中快捷使用最好能并标明注释StrafterStrafterLastStrasciiStrbeforeStrbeforeLastStrbetweenStrcamelStrcontainsStrcontainsAllStrendsWithStrexcerptStrfinishStrheadli

由于dlang和Laravel的语言结构和函数库不同，因此无法直接实现Laravel的Illuminate\Support\Str类的方法。但是，您可以使用D语言的字符串和数组函数来实现类似的功能。以下是一些可能的实现：

Str::after:

string after(string str, string search) {
    auto index = str.indexOf(search);
    if (index == -1) {
        return "";
    }
    return str[index + search.length .. $];
}

Str::afterLast:

string afterLast(string str, string search) {
    auto index = str.lastIndexOf(search);
    if (index == -1) {
        return "";
    }
    return str[index + search.length .. $];
}

Str::ascii:

string ascii(string str) {
    // Replace non-ASCII characters with their ASCII equivalents
    // For example, "é" becomes "e"
    return str.normalize(NormalizationForm.C).filter!(c => c.isAscii).lower;
}

Str::before:

string before(string str, string search) {
    auto index = str.indexOf(search);
    if (index == -1) {
        return "";
    }
    return str[0 .. index];
}

Str::beforeLast:

string beforeLast(string str, string search) {
    auto index = str.lastIndexOf(search);
    if (index == -1) {
        return "";
    }
    return str[0 .. index];
}

Str::between:

string between(string str, string start, string end) {
    auto startIndex = str.indexOf(start) + start.length;
    if (startIndex == -1) {
        return "";
    }
    auto endIndex = str.indexOf(end, startIndex);
    if (endIndex == -1) {
        return "";
    }
    return str[startIndex .. endIndex];
}

Str::camel:

string camel(string str) {
    return str.split(["_", "-", " "]).map!(w => w.capitalize).join("");
}

Str::contains:

bool contains(string str, string search) {
    return str.indexOf(search) != -1;
}

Str::containsAll:

bool containsAll(string str, string[] searches) {
    return searches.all!(s => str.indexOf(s) != -1);
}

Str::endsWith:

bool endsWith(string str, string search) {
    return str.endsWith(search);
}

Str::excerpt:

string excerpt(string str, int length, string ending = "…") {
    if (str.length <= length) {
        return str;
    }
    return str[0 .. length] ~ ending;
}

Str::finish:

string finish(string str, string ending) {
    if (str.endsWith(ending)) {
        return str;
    }
    return str ~ ending;
}

Str::headline:

string headline(string str) {
    return str.split("\n").map!(s => s.trim).filter!(s => !s.empty).join("\n\n");
}

Str::is:

bool is(string str, string pattern) {
    auto regex = Regex(pattern);
    return regex.search(str).count > 0;
}

Str::isAscii:

bool isAscii(string str) {
    return str.filter!(c => !c.isAscii).empty;
}

Str::isUuid:

bool isUuid(string str) {
    auto regex = Regex("[a-fA-F0-9]{8}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{12}");
    return regex.match(str).count > 0;
}
