A database/sql driver that wraps github.com/go-sql-driver/mysql with a connection string refering to a ~/.mylogin section

mylogin-driver - Go database/sql driver for MySQL loading credentials from ~/.mylogin.cnf

mylogin-driver provides a MySQL driver for database/sql. This is just a wrapper around github.com/go-sql-driver/mysql with a different connection string syntax that allows to read server address and credentials from ~/.mylogin.cnf.

About mylogin.cnf:

• https://dev.mysql.com/doc/refman/8.0/en/mysql-config-editor.html
• https://dev.mysql.com/doc/mysql-utilities/1.5/en/mysql-utils-intro-connspec-mylogin.cnf.html

See also package github.com/dolmen-go/mylogin that provides low-level access to ~/.mylogin.cnf reading and writing.

Usage

import (
    "database/sql"
    _ "github.com/dolmen-go/mylogin-driver/register"
)

db, err := sql.Open("mylogin", "[filepath//]<section>/[<database>]")

Example

Here is an example with the public MySQL server provided by ensembl.org.

Create MySQL credentials in a section named client_ensembl in ~/.mylogin.cnf:

$ mysql_config_editor set -G client_ensembl -h ensembldb.ensembl.org -P 5306 -u anonymous -p
$ cat >main.go <<EOF
package main

import (
    "database/sql"
    "fmt"
    _ "github.com/dolmen-go/mylogin-driver/register"
)

func main() {
    db, _ := sql.Open("mylogin", "client_ensembl/")
    var s string
    _ = db.QueryRow("SELECT NOW()").Scan(&s)
    fmt.Println(s)
}
EOF
$ go run main.go
