        It's a custom prompt settings for the clickhouse-client

        Possible macros:
            {host}
            {port}
            {user}
            {display_name}

        You can also use colored prompt, like in [1].

          [1]: https://misc.flogisoft.com/bash/tip_colors_and_formatting

        But note, that ClickHouse does not use readline anymore, instead it uses
        replxx. This means that you don't need the following:
        - RL_PROMPT_START_IGNORE (\001)
        - RL_PROMPT_END_IGNORE   (\002)
    -->
    <prompt_by_server_display_name>
        <default>{display_name} :) </default>
        <test>{display_name} \e[1;32m:)\e[0m </test> <!-- if it matched to the substring "test" in the server display name - -->
        <production>{display_name} \e[1;31m:)\e[0m </production> <!-- if it matched to the substring "production" in the server display name -->
    </prompt_by_server_display_name>

    <!--
        Settings adjustable via command-line parameters
        can take their defaults from that config file, see examples:

    <host>127.0.0.1</host>
    <port>9440</port>
    <secure>1</secure>
    <user>dbuser</user>
    <password>dbpwd123</password>

    <history_file>/home/user/clickhouse_custom_history.log</history_file>
    <max_parser_depth>2500</max_parser_depth>

        The same can be done on user-level configuration, just create & adjust: ~/.clickhouse-client/config.xml

                 "host" is not the same as "hostname" since you may want to have different settings for one host,
                 and in this case you can add "prod" and "prod_readonly".
