How to Handle Long Lines in fmt.Sprintf

Formatting long strings in fmt.Sprintf can present difficulties when attempting to maintain code readability. To address this issue, consider the following techniques:

String Concatenation

Utilize string concatenation to construct a single string on multiple lines. This allows you to break up the string without cluttering a single line:

<code class="go">fmt.Sprintf("a:%s, b:%s " +
    " ...... this goes really long",
    s1, s2)</code>

In this example, the extended string is generated at compile time due to the constant expression nature of string concatenation.

Raw String Literals

Alternative, leverage raw string literals to split the string at embedded newlines. This approach enables line breaks within the string:

<code class="go">fmt.Sprintf(`this text is on the first line
and this text is on the second line,
and third`)</code>
