functoria 2.2.0 · OCaml Package

Functions for reading various options from a command line.

val setup_log : unit Cmdliner.Term.t

val config_file : (Fpath.t -> unit) -> unit Cmdliner.Term.t

val build_dir : (Fpath.t -> unit) -> unit Cmdliner.Term.t

val output : string option Cmdliner.Term.t

val read_full_eval : string array -> bool option

read_full_eval argv reads the --eval option from argv; the return value is None if option is absent in argv.

type 'a configure_args = {

result : 'a;
output : string option;

}

A value of type configure_args is the result of parsing the arguments of a configure subcommand.

type 'a describe_args = {

result : 'a;
dotcmd : string;
dot : bool;
output : string option;

}

A value of type describe_args is the result of parsing the arguments to a describe subcommand.

The result field holds the result of parsing the "additional" arguments whose specification is passed as the describe argument to parse_args.

type 'a action =

| Configure of 'a configure_args
| Describe of 'a describe_args
| Build of 'a
| Clean of 'a
| Help
(*
A value of type action is the result of parsing command-line arguments using parse_args.

val pp_action : 'a Fmt.t -> 'a action Fmt.t

pp_action is the pretty-printer for actions.

val parse_args : 
  ?help_ppf:Format.formatter ->
  ?err_ppf:Format.formatter ->
  name:string ->
  version:string ->
  configure:'a Cmdliner.Term.t ->
  describe:'a Cmdliner.Term.t ->
  build:'a Cmdliner.Term.t ->
  clean:'a Cmdliner.Term.t ->
  help:_ Cmdliner.Term.t ->
  string array ->
  'a action Cmdliner.Term.result

Parse the functoria command line. The arguments to ~configure, ~describe, etc., describe extra command-line arguments that should be accepted by the corresponding subcommands. The full argument specification is as follows:

There are no side effects, save for the printing of usage messages and other help when either the 'help' subcommand or no subcommand is specified.
