TOML Grammar

A Lean encoding of the v1.0.0 TOML grammar (en, [abnf]]2) using Lean.Parser objects. The current encoding elides the use of tokens entirely, relying purely on custom parser functions.

def Lake.Toml.isControlChar (c : Char) : Bool

Is it a TOML control character? (excludes tabs and spaces)

Trailing Functions

def Lake.Toml.wsFn : Lean.Parser.ParserFn

Consume optional horizontal whitespace (i.e., tab or space).

def Lake.Toml.newlineFn : Lean.Parser.ParserFn

Consume a newline.

def Lake.Toml.commentFn : Lean.Parser.ParserFn

Consumes a line comment.

partial def Lake.Toml.wsNewlineFn : Lean.Parser.ParserFn

Consume optional whitespace (space, tab, or newline).

partial def Lake.Toml.trailingFn : Lean.Parser.ParserFn

Consume optional sequence of whitespace / newline(s) / comment (s).

Strings

def Lake.Toml.isEscapeChar (c : Char) : Bool

A TOML character escape.

def Lake.Toml.basicStringFn : Lean.Parser.ParserFn

def Lake.Toml.literalStringFn : Lean.Parser.ParserFn

def Lake.Toml.mlLiteralStringFn : Lean.Parser.ParserFn

def Lake.Toml.mlBasicStringFn : Lean.Parser.ParserFn

Numerals (Date-Times, Floats, and Integers)

def Lake.Toml.timeFn (allowOffset : Bool := false) : Lean.Parser.ParserFn

def Lake.Toml.dateTimeFn : Lean.Parser.ParserFn

def Lake.Toml.numeralFn : Lean.Parser.ParserFn
