DSNExec

DSNExec is a cli tool that watches files and then reacts to those changes by executing commands. The commands can be SQL commands or they can be shell commands.

Configuration

Sources: driver: The driver is used for parsing the source file. The parser allows the content of the file to be referenced in a template. There are several drivers available.

    json:     a json parser
    yaml:     a yaml parser
    postgres: a postgres connection string parser
    none:     does not try to parse the input file

filename: the name of the file to use as a source.

Destination: driver: A database driver to execute the commands with. This is used with the golang sql package. A "shelldb" driver also is registed so that any executable can be run with the same abstraction.

dsn:    A DSN for the driver to connect with.

Commands: command: A SQL command to exectute. This sql command is parsed with the golang text/template package with the sources map as the template context.

args:       An array of arguments to the SQL command. The args are parsed with
            the golang text/template package with the sources map as the
            template context. 
            (Note - If you intent to fire DDL queries, then put full go template expressions in the command. 
            As unlike for DML queries, underlying prepare statement does not consider arguments passed when the query is DDL.)
