Functions

app(List<String> arguments, String versionString, String preAmble, String quitStatement, Map<String, dynamic> tokenMap, Map<String, dynamic> grammar, List<String> cosmeticTokens, Map<String, dynamic> functionMap) → void

This method contains the entire app/interpreter. This is the only method you need to call!

constructParseTree(Map<String, dynamic> grammar, List<String> cosmeticTokens, List parsedTokens) → List

This method builds an AST of the matched tokens, removes all unneeded tokens and constructs an intermediate representation by trying to "understand" the code it is given.

evaluateLine(Map<String, dynamic> tokenMap, String text, Map<String, dynamic> grammar, List<String> cosmeticTokens, Map<String, dynamic> functionMap) → void

This method executes each line of a given line of text!

executeParseTree(List parseTree, Map<String, dynamic> functionMap) → void

This method takes the intermediate representation and AST from the parse tree and executes a function with a given number of arguments. Each function has a dynamic list of arguments. This method adds to that list and runs the result.

parseText(Map<String, dynamic> tokenMap, String text) → List

This method synthesizes the matched tokens from a string of text. The tokens are supplied as a map.

readFile(String fileName, Map<String, dynamic> tokenMap, Map<String, dynamic> grammar, List<String> cosmeticTokens, Map<String, dynamic> functionMap) → void

This method reads the contents of a file and executes each line of code.

shell(String preAmble, String quitStatement, Map<String, dynamic> tokenMap, Map<String, dynamic> grammar, List<String> cosmeticTokens, Map<String, dynamic> functionMap) → void

This method provides a shell method. It can be customized.

visualParseTree(List parseTree) → void

This method prints a visual of the AST.
