Merge Text Lines, String Join lines online

The Merge Text Lines tool is an online tool that can take multiple lines of text and merge them into a single line. It is useful for cleaning up long text strings and making them easier to read. It can also be used to combine multiple lines of code into a single command. The tool removes any existing line breaks and whitespace, so the resulting text will be easier to work with. The Merge Text Lines tool is an essential tool for any text editor or programmer.

Examples in programming languages

Php Example 

$combined = implode(" ", array_filter($lines));

Nodejs Example 

const combined = lines.filter(Boolean).join(' ');

Java Example 

String combined = String.join(" ", lines.stream().filter(StringUtils::isNotBlank).collect(Collectors.toList()));

C Example

for (int i = 0; i < lines_count; i++) {
    if (lines[i] != NULL) {
        if (combined == NULL) {
            combined = strdup(lines[i]);
        } else {
            char *tmp = (char*)malloc(strlen(combined) + strlen(lines[i]) + 2);
            if (tmp == NULL) {
                free(combined);
                combined = NULL;
                break;
            }
            sprintf(tmp, "%s %s", combined, lines[i]);
            free(combined);
            combined = tmp;
        }
    }
}

std::string combined;
for (const std::string& line : lines) {
    if (!line.empty()) {
        if (combined.empty()) {

        } else {
            combined += " " + line;
        }
    }
}
