Beautify selection as another language

[oschwald]

As far as I can tell, there is no way to currently beautify a selection of code in a specific language that is different than the file's language. My primary use case for this feature would be beautifying SQL that is embedded in string literals, although I imagine it could also be useful for beautifying other embedded code or markup.

Could you also provide a tiny code sample? It will give us something to test against.

Sure, here are two made up examples where I'd like to be able to beautify the SQL within the other code.

Perl

my $sql = <<'SQL';
SELECT fname, lname 
FROM people 
WHERE id >= ? AND id < ?
SQL

my $sth = $dbh->prepare($sql);
$sth->execute(1, 10);
while (my @row = $sth->fetchrow_array) {
   print "fname: $row[0]  lname: $row[1]\n";
}

Go

package main

import (
    "database/sql"
    "log"

    _ "github.com/go-sql-driver/mysql"
)

func main() {
    var (
        id   int
        name string
    )

    db, err := sql.Open("mysql",
        "user:password@tcp(127.0.0.1:3306)/hello")
    if err != nil {
        log.Fatal(err)
    }
    defer db.Close()

    sql := `
SELECT id,
       name
FROM "user"
WHERE name='Bob'
AND   date='2014-01-10'
`

    rows, err := db.Query(sql)

    if err != nil {
        log.Fatal(err)
    }
    defer rows.Close()
    for rows.Next() {
        err := rows.Scan(&id, &name)
        if err != nil {
            log.Fatal(err)
        }
        log.Println(id, name)
    }
    err = rows.Err()
    if err != nil {
        log.Fatal(err)
    }
}

Perhaps a right click option Beautify As... that open a list of grammars.
