Type AST

Parsing methods

val parse_string_rec : Token.token_type list -> string * Token.token_type list

Parse a string recursively until it encounters a closing quote

val parse_line : 
  Token.token_type list ->
  Token.token_type list * parameters ast list

Parse a line (a list of tokens) into a a list of ASTs

val parse_file : Token.token_type list -> parameters ast list

Parse a file using parse line

Parameters/Arguments utility functions

Parameters algebra function

val add_numbers : parameters -> parameters -> parameters

Adds two parameters

raises a
baguette exception if the type are non-summable

val equality : parameters -> parameters -> parameters

Checks for equality between two parameters

val inferior_large : parameters -> parameters -> parameters

Checks for the <= between two parameters

val inferior : parameters -> parameters -> parameters

Checks for the < between two parameters

val superior_large : parameters -> parameters -> parameters

Checks for the >= between two parameters

val superior : parameters -> parameters -> parameters

Checks for the > between two parameters

val mult_numbers : parameters -> parameters -> parameters

Multiply two numbers

raises a
baguette sharp type error if the arguments are not numbers

val expn : parameters -> parameters -> parameters

Exponentiate a^b

raises a
baguette sharp type error if the arguments are not numbers

val divide_numbers : parameters -> parameters -> parameters

Divide a/b

raises a
baguette sharp type error if the arguments are not numbers

val substract_numbers : parameters -> parameters -> parameters

raises a
baguette sharp type error if the arguments are not numbers

val apply_binary_operator : 
  (bool -> bool -> bool) ->
  parameters ->
  parameters ->
  parameters

Printing utility

val print_argument : arguments -> string

Transforms an argument into a string Type: value

val print_lit_argument : arguments -> string

Transforms only the value of an argument

val print_argument_for_repl : arguments -> string

Transform an argument into a string for the REPL

val print_parameter : ?fortbl:bool -> parameters -> string

Transforms a parameter into a string

parameter fortbl
specify if we are printing an array to simplify the output

val print_pretty_arguments : parameters list -> string

Transform a list of parameters into a string representation

val print_pretty_node : parameters ast -> string

Pretty-print (transforms into a string) an AST
