type t = private {debug_level : int; | Controls debug messages, 0 to disable |
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 |
