Module perspective_viewer::exprtk

Structs

• CompletionItemSuggestion
• Cursor
  Because ExprTK reports errors in column/row coordinates and visually needs to be applied to an entire token rather than a single character, we need fairly obnoxious counter logic to figure out how to generate the resulting syntax-highlighted HTML. The Counter<'a> struct encpsulates this logic, generating a NodeRef to any autocomplete-able <span> tokens, as well as other convenient data for HTML rendering, and can be called incrementally while iterating tokens after parsing.

Enums

• Token
  Syntax-highlightable ExprTK tokens. We had the option of implemnting this alternatively as pub struct Token(TokenType, &'a str);, but I felt this was less ergonomic for the frequent pattern matching necessary when handling enum tokens.

Constants

• COMPLETIONS
• COMPLETION_COLUMN_NAMES

Functions

• tokenize
  Parse a string representing an ExprTK Expression Column into Tokens. A token list is sufficient for syntax-highlighting purposes, faster than a full parser and much easier to write a renderer for.
