Struct MathypadCore

pub struct MathypadCore {
    pub text_lines: Vec<String>,
    pub cursor_line: usize,
    pub cursor_col: usize,
    pub results: Vec<Option<String>>,
    pub variables: HashMap<String, String>,
}

Core application state containing text, results, and variables This is UI-agnostic and can be used by both TUI and web implementations

Fields

text_lines: Vec<String>

The text content of each line

cursor_line: usize

Current cursor line position (0-indexed)

cursor_col: usize

Current cursor column position (0-indexed, in characters)

results: Vec<Option<String>>

Evaluation results for each line (None means no result or error)

variables: HashMap<String, String>

Variable storage (variable_name -> value_string)

Implementations

impl MathypadCore

pub fn new() -> Self

Create a new empty MathypadCore instance

pub fn from_lines(lines: Vec<String>) -> Self

Create a MathypadCore from a list of text lines

pub fn insert_char(&mut self, c: char)

Insert a character at the current cursor position

pub fn delete_char(&mut self)

Delete the character before the cursor

pub fn new_line(&mut self)

Insert a new line at the current cursor position

pub fn update_result(&mut self, line_index: usize)

Update the result for a specific line

pub fn recalculate_all(&mut self)

Recalculate all results and variables

pub fn move_cursor_to(&mut self, line: usize, col: usize)

Move cursor to a specific position

pub fn current_line(&self) -> &str

Get the current line content

pub fn current_result(&self) -> Option<&str>

Get the result for the current line

pub fn set_content(&mut self, content: &str)

Set text content from a string (splitting into lines)

pub fn get_content(&self) -> String

Get content as a single string

pub fn update_content_with_line_references(&mut self, new_content: &str)

Update content with line reference updating (for incremental edits) This detects line insertions/deletions and updates references accordingly
