Module OpamCoreConfig

Configuration options for the core lib (record, global reference and setter)

module StringMap : Map.S with type key = string
type t = private {
debug_level : int;(*

Controls debug messages, 0 to disable

*)
debug_sections : int option StringMap.t;(*

Controls which sections display debugging messages. If empty, all messages are displayed.

*)
verbose_level : int;(*

Controls printing of external commands and output, 0 to disable, more means print more low-level commands

*)
color : [ `Always | `Never | `Auto ];(*

Console ANSI color control

*)
utf8 : [ `Extended | `Always | `Never | `Auto ];(*

Controls usage of UTF8 in OPAM-generated messages. Extended adds camel emojis

*)
disp_status_line : [ `Always | `Never | `Auto ];(*

Controls on-line display of parallel commands being run, using ANSI escapes

*)
answer : bool option;(*

Affects interactive questions in OpamConsole: auto-answer with the given bool if Some

*)
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)
