Utility Module for S-expression Conversions
include module type of Sexplib0.Sexp_convval default_string_of_float : (float -> string) refdefault_string_of_float reference to the default function used to convert floats to strings.
Initially set to fun n -> sprintf "%.20G" n.
val write_old_option_format : bool refwrite_old_option_format reference for the default option format used to write option values. If set to true, the old-style option format will be used, the new-style one otherwise.
Initially set to true.
val read_old_option_format : bool refread_old_option_format reference for the default option format used to read option values. Of_sexp_error will be raised with old-style option values if this reference is set to false. Reading new-style option values is always supported. Using a global reference instead of changing the converter calling conventions is the only way to avoid breaking old code with the standard macros.
Initially set to true.
We re-export a tail recursive map function, because some modules override the standard library functions (e.g. StdLabels) which wrecks havoc with the camlp4 extension.
