Add a new macro as an extension

pub fn add_runtime_rules(
    &mut self,
    rules: Vec<(impl AsRef<str>, &str, &str)>
) -> RadResult<()>

Add runtime rules without builder pattern

Args

The order of argument is “name, args, body”

Example

processor.add_runtime_rules(vec![("macro_name","macro_arg1 macro_arg2","macro_body=$macro_arg1()")]);

pub fn add_static_rules(
    &mut self,
    rules: Vec<(impl AsRef<str>, impl AsRef<str>)>

pub fn from_string(&mut self, content: &str) -> RadResult<Option<String>>

Read from string

pub fn from_stdin(&mut self) -> RadResult<Option<String>>

Read from standard input

If debug mode is enabled this, doesn’t read stdin line by line but by chunk because user input is also a standard input and processor cannot distinguish the two

This will print log_error if auth was enabled with warning

@return If auth is enabled or not
