Mo is a mustache template rendering software written in bash. It inserts
environment variables into templates.
@ -21,19 +20,59 @@ Simple usage:
Options:
--allow-function-arguments
Permit functions to be called with additional arguments. Otherwise,
the only way to get access to the arguments is to use the
MO_FUNCTION_ARGS environment variable.
-d, --debug
Enable debug logging to stderr.
-u, --fail-not-set
Fail upon expansion of an unset variable.
Fail upon expansion of an unset variable. Will silently ignore by
default. Alternately, set MO_FAIL_ON_UNSET to a non-empty value.
-x, --fail-on-function
Fail when a function returns a non-zero status code.
Fail when a function returns a non-zero status code instead of
silently ignoring it. Alternately, set MO_FAIL_ON_FUNCTION to a
non-empty value.
-f, --fail-on-file
Fail when a file (from command-line or partial) does not exist.
Alternately, set MO_FAIL_ON_FILE to a non-empty value.
-e, --false
Treat the string "false" as empty for conditionals.
Treat the string "false" as empty for conditionals. Alternately,
set MO_FALSE_IS_EMPTY to a non-empty value.
-h, --help
This message.
-s=FILE, --source=FILE
Load FILE into the environment before processing templates.
Can be used multiple times.
-d, --debug
Enable debug logging to stderr.
-- Indicate the end of options. All arguments after this will be
treated as filenames only. Use when filenames may start with
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.
MO_DEBUG - When set to a non-empty value, additional debug information is
written to stderr.
MO_FUNCTION_ARGS - Arguments passed to the function.
MO_FAIL_ON_FILE - If a filename from the command-line is missing or a
partial does not exist, abort with an error.
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.
Mo is under a MIT style licence with an additional non-advertising clause.
