Struct Interpreter

pub struct Interpreter<Buffer: IoWrite, LibCore: StdCore> { /* private fields */ }

Implementations

impl<Buffer: IoWrite, LibCore: StdCore> Interpreter<Buffer, LibCore>

pub fn new(buffer: Buffer) -> Self

Create a new interpreter instance

pub fn repl(&mut self, repl: bool) -> &mut Self

Enable or disable REPL mode (print last value to output buffer)

pub fn with_search_path(&mut self, path: PathBuf) -> Result<(), Error>

Add module search path

pub fn with_color(buffer: Buffer) -> Self

Enable ansi colored error message

pub fn load_ext( &mut self, extension: Extension<Buffer>, ) -> Result<(), Extension<Buffer>>

pub fn impl_extern_function<F>(&mut self, name: impl Into<String>, f: F)

where F: Fn(&mut State<'_, Buffer>, &[DiatomValue], &mut Buffer) -> Result<DiatomValue, String> + 'static + Send + Sync,

Directly declare external function as variable

pub fn verify_input_completeness(&self, code: impl AsRef<str>) -> bool

Check if input is completeness

Incomplete input usually contains unclosed parentheses, quotes or open expression.

pub fn decompile( &mut self, code: impl AsRef<str>, source: impl AsRef<OsStr>, is_phony: bool, ) -> Result<String, String>

Show decompiled byte code for given source code.

If compilation failed, Err will be returned.

pub fn replace_buffer(&mut self, buffer: Buffer) -> Buffer

Replace output buffer and get the old one

pub fn exec( &mut self, code: impl AsRef<str>, source: impl AsRef<OsStr>, is_phony: bool, ) -> Result<(), String>

Run a piece of diatom source code

Parameters

• code - Source code
• source - name of source code file or where it is from
• is_phony - Whether source is a real path or a place holder

Return

• Return the output of the program
• If compilation failed or error occurs durning execution, an Err(String) that illustrates the error is returned.
