//! This crate is a parser for the 'Trinitry' (not 'Trinity') language, used to map all sort of
|
||||
//! Functions to a memorable command.
|
||||
//!
|
||||
//! This parser is more of a validator, as Trinitry does not support any language features besides
|
||||
//! the aforementioned commands and arguments. That includes some simple constructs like: '||' (OR)
|
||||
//! or '&&' (AND). If you need these features, simple write them in the language, you've written your
|
||||
//! Function in.
|
||||
//!
|
||||
//! # General specification
|
||||
//! ## Command
|
||||
//! Basically every command can be a series of alphanumeric ASCII values.
|
||||
//!
|
||||
//! Correctly spoken, the Language, containing all valid command names, is just the Kleene closure
|
||||
//! over an Alphabet $\Sigma$, which contains all alphanumeric characters:
|
||||
//! $$ \Sigma_{cmd} = \\{x | 0 \leqslant x \leqslant 9\\} \cup \\{x | "a" \leqslant x \leqslant "z"\\} \cup \\{x | "A" \leqslant x \leqslant "Z"\\} \cup \\{"\\_", "\text{-}", "."\\} $$
|
||||
//!
|
||||
//! ## Argument
|
||||
//! Arguments are similar to the command, although they can also contain spaces and quotes,
|
||||
//! if it's quoted and additional characters (here notated as "$\\dots{}$"):
|
||||
//! $$ \Sigma_{args-quoted} = \Sigma_{cmd} \cup \\{"\\text{"}", "\\ ", \\dots{}\\} $$
|
||||
//! $$ \Sigma_{args-single-quoted} = \Sigma_{cmd} \cup \\{"'", "\\ ", \\dots{}\\} $$
|
||||
//! $$ \Sigma_{args} = \Sigma_{cmd} \cup \\{\\dots{}\\} $$
|
||||
//! Look at the [trinitry.pest](../../../src/trinitry.pest) file for a full list of the additional
|
||||
//! allowed characters.
|
||||
//!
|
||||
//! # Examples
|
||||
//! ## Command
|
||||
//! A valid command would be something like that:
|
||||
//! ```text
|
||||
//! quit
|
||||
//! ```
|
||||
//! something like that would not be valid however, as Trinitry does not support these 'complex'
|
||||
//! language features:
|
||||
//! ```text
|
||||
//! write && quit
|
||||
//! ```
|
||||
//! ## Arguments
|
||||
//! A valid argumented command would be:
|
||||
//! ```text
|
||||
//! lua "function() print('Hi!') end"
|
||||
//! ```
|
||||
//! Whilst this would not be valid (that is, it would very likely not be what you want):
|
||||
//! ```text
|
||||
//! lua "function() print("Hi!") end"
|
||||
//! ```
|
||||
//! as the double quotes in the print statement actually unquote the argument, leaving you with
|
||||
//! three arguments:
|
||||
//! 1. `function() print(`
|
||||
//! 1. `Hi!`
|
||||
//! 1. `) end`
