(** [varname_of_string ~hyphen:c s] Transform a string [s] into a variable name,
following this convention: no digit at the beginning, lowercase, only a-z
and 0-9 chars. Whenever there is a problem, use an hyphen.
*)

(** [varname_concat ~hyphen p s] Concat variable name, removing hyphen at end
of [p] and at beginning of [s].
*)
val varname_concat: ?hyphen:char -> string -> string -> string
(** [is_varname str] Check that the string [str] is a valid varname. See
{!varname_of_string} for definition.
*)

(** {2 Fail with Printf.sprintf} *)
(** This function raise the [Failure] exception just as [failwith]
except that one specify the string raised through a format string.

(** [split s]: the string [s] is interpreted as command line
arguments and splitted into its components (un-escaped). For
example [split "a \"b c\" d" = ["a"; "b c"; "d"]]. Note that
[split "" = []]. It is possible that substitutions such as "$a"
(resp. "$(a b)") may be transformed into "$\{a\}" (resp. "$\{a b\}"). *)
val split: string -> string list
(** [escape s] quote [s] if needed to protect spaces, '"' and '\''
so it reads as a single argument in a POSIX shell command, the
content of which is identical to [s] (interpreted with OCaml
conventions). If quoted, the returned string will start and end
with '"'. The original string [s] is returned if no quoting is
necessary. *)
val escape: string -> string
(** [unescape s] returns a string [s'] removing all backslashes
preceding a char. *)
