Module parser 

Structs

Parser

Simple parser type that can be used to convert an input stream of tokens into a tree (of a particular tree node type)

ParserDidNotConverge

Error indicating that finish() was called when the stack does not have exactly one treenode item in it

ParserLookaheadEmpty

Error indicating that a token cannot be accepted by the parser because there is no token in the lookahead

ParserStackTooSmall

Error indicating there are not enough tokens in the parser stack to perform a ‘reduce’ operation

TokenMatch

A match from the tokenizer

Tokenizer

A basic async tokenizer

Enums

CommandToken

Tokens from the command stream

ExpectedTokenError

JsonInputType

What type of ‘more’ input was expected

JsonParseError

Errors that can occur while parsing JSON

JsonToken

The tokens that make up the JSON language

ParsedJson

The parsed form of a JSON statement. This can incorporate variables, as well as the parts of a standard JSON value

ParserStackEntry

An entry for the parser stack used by the ParserClass

TokenMatchResult

Results of matching some lookahead aganst a token

Traits

TokenMatcher

Trait implemented by matchers that can recognise a token

Functions

command_parse

Parses a command from an input stream

command_read_token

Reads a command token from the tokenizer

json_parse_array

Attempts to parse a JSON array starting at the current location in the tokenizer, leaving the result on top of the stack in the parser (or returning an error state if the value is not recognised)

json_parse_command_substitution

Parses a commmand substitution, contained within <> operators

json_parse_number

Attempts to parse a JSON object starting at the current location in the tokenizer, leaving the result on top of the stack in the parser (or returning an error state if the value is not recognised)

json_parse_object

Attempts to parse a JSON object starting at the current location in the tokenizer, leaving the result on top of the stack in the parser (or returning an error state if the value is not recognised)

json_parse_string

Attempts to parse a JSON string starting at the current location in the tokenizer, leaving the result on top of the stack in the parser (or returning an error state if the value is not recognised)

json_parse_value

Attempts to parse a JSON value starting at the current location in the tokenizer, leaving the result on top of the stack in the parser (or returning an error state if the value is not recognised)

json_parse_value_with_extensions

Attempts to parse a JSON value starting at the current location in the tokenizer, leaving the result on top of the stack in the parser (or returning an error state if the value is not recognised)

json_read_token

Reads a JSON token from the tokenizer

json_read_token_or_newline

Reads a JSON token from the tokenizer, including any newlines that are encountered
