Template Example

This example demonstrates how to use templates in GXL.

#![allow(unused)]
fn main() {
extern mod os { path = "../../_gal/mods"; }

mod base_env {
    env _common {
        gx.vars {
            DOMAIN = "domain";
            SOCK_FILE = "socket";
            GXL_PRJ_ROOT = "./";
        }
    }
    env cli : _common {
        ROOT = "./";
    }
    env unit_test : _common {
        ROOT = "./example";
    }
}

mod envs : base_env {
    #[usage(desp = "default")]
    env default : cli;
    env empty {}
    env ut : unit_test;
}

mod main {
    conf = "${ENV_ROOT}/conf";
    flow conf {
        os.path(dst: "${MAIN_CONF}/used", keep: "true");
        gx.tpl(
            tpl: "${MAIN_CONF}/tpls/",
            dst: "${MAIN_CONF}/used/",
            file: "${MAIN_CONF}/value.json");

        ```cmd
        echo "hello";
        cp ./conf/value.json ./conf/used/back.json;
        ```
    }
}
}

Description

This example shows how to use the gx.tpl command to process template files. In the conf flow, the os.path command is first used to create the target directory, then the gx.tpl command renders template files from the tpls directory based on values in the value.json file and outputs them to the used directory. Finally, an inline shell command block is shown to copy a file.
