Models

hello

A “hello world” sample model

This is a sample model that provides various operations for printing hello world messages.

The message provided, either by default, by a flag, or a file (see each operation for the applicable interface) is printed to standard output and written to a file named output in the run directory.

Operations

default

This operation doesn’t support a user-defined message. Use the from-flag operation with the ‘message’ flag to print an alternative message.

from-file

Print a message from a file

Use the ‘file’ flag to specify the file to print.

Flags

file

File containing the message to print (default is ‘msg.txt’)

from-file-output

Print output from last file-output operation

This operation requires a completed file-output run.

from-flag

Print a message

Use the ‘message’ flag to specify the message to print.

Flags

message

Message to print (default is ‘Hello Guild, from a flag!’)

Model flags

There are no flags defined at the model level.
