How to format a multiline string literal

Question

I am trying to break a string literal into multiple lines to meet my linter's expectations of short lines. Following is the code right now, it passes the linter check:

return nil,
    "",
    errors.Errorf(
            `nil cursor returned when querying for transactions for block hash %s, 
page token %s and limit %d`,
            blockHash,
            pageToken,
            limit,
    )

I don't like the formatting of the string literal. It feels aesthetically wrong ;). Is there a better way to format this? Thanks!

Use string concatenation to construct the string from shorter lines:

errors.Errorf(
        `nil cursor returned when querying for transactions` +
        ` for block hash %s, page token %s and limit %d`,
        blockHash,
        pageToken,
        limit,
 )

You can use string addition:

errors.Errorf(`nil cursor returned when querying for `+
`transactions for block hash %s, page token %s and limit %d`,
            blockHash,
            pageToken,
            limit,
    )
