Struct CodeEditor 

pub struct CodeEditor { /* private fields */ }

A source code editor: monospaced, no wrapping, line numbers, colors for the language, Tab and Shift+Tab to indent, and Enter keeping the indentation. Ctrl or Cmd with Enter is left to shortcuts, so a surrounding Playground can run the code. Diagnostics mark their lines and underline what they cover.

use ravenrs_reactive::State;
use ravenrs_widgets::{CodeDiagnostic, CodeEditor, Ui};

let source = State::new("fn main() {\n    println!(\"hi\");\n}".to_owned());
let editor = CodeEditor::new(source.binding())
    .diagnostics(vec![CodeDiagnostic::error(2, 5, 8, "unknown macro")])
    .rows(8);
let mut ui = Ui::new(editor, ravenrs_style::Theme::raven_dark());
ui.update();

Implementations

impl CodeEditor

pub fn new(value: Binding<String>) -> CodeEditor

An editor of value, as Rust, with line numbers and an indent of 4 spaces.

pub fn language(self, language: CodeLanguage) -> CodeEditor

The language it colors.

pub fn line_numbers(self, shown: bool) -> CodeEditor

Shows or hides the line numbers.

pub fn diagnostics(self, diagnostics: Vec<CodeDiagnostic>) -> CodeEditor

Marks these places.

pub fn indent(self, spaces: usize) -> CodeEditor

How many spaces Tab inserts; at least 1.

pub fn rows(self, rows: usize) -> CodeEditor

How many lines are visible; more scroll. 12 by default.

pub fn fill(self) -> CodeEditor

Takes the height its parent gives, instead of Self::rows.

pub fn read_only(self, read_only: bool) -> CodeEditor

Shows the code without letting it change; it can still be selected and copied.
