module E : sig ... end

type t = private {

debug_level : int;
(*
Controls debug messages, 0 to disable
*)
debug_sections : OpamStd.Config.sections;
(*
Controls which sections display debugging messages. If empty, all messages are displayed.
*)
verbose_level : OpamStd.Config.level;
(*
Controls printing of external commands and output, 0 to disable, more means print more low-level commands
*)
color : OpamStd.Config.when_;
(*
Console ANSI color control
*)
utf8 : OpamStd.Config.when_ext;
(*
Controls usage of UTF8 in OPAM-generated messages. Extended adds camel emojis
*)
disp_status_line : OpamStd.Config.when_;
(*
Controls on-line display of parallel commands being run, using ANSI escapes
*)
confirm_level : [ OpamStd.Config.answer | `undefined ];
yes : bool option;
(*
Affects interactive questions in OpamConsole: used to compute the automatic ansering level
*)
safe_mode : bool;
(*
Fail on writes or delays, don't ask questions (for quick queries, e.g. for shell completion)
*)
log_dir : string;
(*
Where to store log and temporary files (output from commands...)
*)
keep_log_dir : bool;
(*
Whether to cleanup temporary and log files on exit
*)
errlog_length : int;
(*
The number of log lines displayed on process error. 0 for all
*)
merged_output : bool;
(*
If set, stderr of commands is merged into their stdout
*)
use_openssl : bool;
(*
If false, will use built-in hash functions without checking for an openssl executable first
*)
precise_tracking : bool;
(*
If set, will take full md5 of all files when checking diffs (to track installations), rather than rely on just file size and mtime
*)
set : bool;
(*
Options have not yet been initialised (i.e. defaults are active)
*)

val setk : (t -> 'a) -> t -> 'a options_fun

val r : t ref

val update : ?noop:_ -> (unit -> unit) options_fun

val init : ?noop:_ -> (unit -> unit) options_fun

Sets the OpamCoreConfig options, reading the environment to get default values when unspecified

val initk : 'a -> 'a options_fun

Like init, but returns the given value. For optional argument stacking

val answer_is : OpamStd.Config.answer -> bool

Automatic answering levels * `ask: prompt and ask user * `no: answer no to all opam questions * `yes: answer yes to all opam questions * `unsafe_yes: answer yes to all opam question and launch system package command wit non interactive options If confirm-level is set (from cli or environment variable), its value is returned. Otherwise, is takes last yes/no cli flag. For environment variables, if OPAMYES is set to true, it has priority over OPAMNO. As other environment variables, cli flags content is taken if given. answer_is and answer_is_yes computes the answer lazily, use answer in case of config update.

val answer_is_yes : unit -> bool

val answer : unit -> OpamStd.Config.answer

val developer : bool

true if OPAM was compiled in developer mode
