mo()
----
`mo()`
------
Public: Template parser function. Writes templates to stdout.
* $0 - Name of the mo file, used for getting the help message.
* --fail-not-set - Fail upon expansion of an unset variable. Default behavior is to silently ignore and expand into empty string.
* --false - Treat "false" as an empty value. You may set the MO_FALSE_IS_EMPTY environment variable instead to a non-empty value to enable this behavior.
* --help - Display a help message.
* --source=FILE - Source a file into the environment before processint template files.
* -- - Used to indicate the end of options. You may optionally use this when filenames may start with two hyphens.
* $@ - Filenames to parse.
Options:
--allow-function-arguments
Permit functions in templates to be called with additional arguments. This puts template data directly in to the path of an eval statement. Use with caution. Not listed in the help because it only makes sense when mo is sourced.
-u, --fail-not-set
Fail upon expansion of an unset variable. Default behavior is to silently ignore and expand into empty string.
-x, --fail-on-function
Fail when a function used by a template returns an error status code. Alternately, ou may set the MO_FAIL_ON_FUNCTION environment variable to a non-empty value to enable this behavior.
-e, --false
Treat "false" as an empty value. You may set the MO_FALSE_IS_EMPTY environment variable instead to a non-empty value to enable this behavior.
-h, --help
Display a help message.
-s=FILE, --source=FILE
Source a file into the environment before processing template files.
--
Used to indicate the end of options. You may optionally use this when filenames may start with two hyphens.
Mo uses the following environment variables:
* MO_ALLOW_FUNCTION_ARGUMENTS - When set to a non-empty value, this allows functions referenced in templates to receive additional options and arguments. This puts the content from the template directly into an eval statement. Use with extreme care.
* MO_FUNCTION_ARGS - Arguments passed to the function
* MO_FAIL_ON_FUNCTION - If a function returns a non-zero status code, abort with an error.
* MO_FAIL_ON_UNSET - When set to a non-empty value, expansion of an unset env variable will be aborted with an error.
* MO_FALSE_IS_EMPTY - When set to a non-empty value, the string "false" will be treated as an empty value for the purposes of conditionals.
* MO_ORIGINAL_COMMAND - Used to find the `mo` program in order to generate a help message.
