Module B0_driver.ConfSource

Driver configuration.

Default file names

Sourceval b0_file_name : string

b0_file_name is "B0.ml" the default B0 file name.

Sourceval drivers_dir_name : string

driver_dir_name is ".drivers" the default directory for drivers in the b0 directory.

Configurations

Sourcetype t

The type for configurations.

Sourceval v : b0_dir:B0_std.Fpath.t -> b0_file:B0_std.Fpath.t option -> cache_dir:B0_std.Fpath.t -> cwd:B0_std.Fpath.t -> code:B00_ocaml.Conf.code option -> hash_fun:(module B0_std.Hash.T) -> jobs:int -> log_level:B0_std.Log.level -> no_pager:bool -> tty_cap:B0_std.Tty.cap -> unit -> t

v constructs a configuration with given attributes. See the accessors for semantics.

Sourceval b0_file : t -> B0_std.Fpath.t option

b0_file is the absolute path to the B0 file (if any).

Sourceval b0_dir : t -> B0_std.Fpath.t

b0_dir is the absolute path to the b0 directory.

Sourceval cache_dir : t -> B0_std.Fpath.t

cache_dir is the absolute path to the cache directory.

Sourceval cwd : t -> B0_std.Fpath.t

cwd is the absolute path to the current working directory.

Sourceval code : t -> B00_ocaml.Conf.code option

code is the code to which the driver is compiled.

Sourceval hash_fun : t -> (module B0_std.Hash.T)

hash_fun is the hash function to use for build caching.

Sourceval jobs : t -> int

jobs is the maximal number of spawns allowed.

Sourceval log_level : t -> B0_std.Log.level

log_level is the desired log level.

Sourceval memo : t -> (B00.Memo.t, string) result

memo is the memoizer for the configuration.

Sourceval no_pager : t -> bool

no_pager indicates no paging is desired on stdout.

Sourceval tty_cap : t -> B0_std.Tty.cap

tty_cap is the terminal capability to assume for outputs.

Derived data

Sourceval get_b0_file : t -> (B0_std.Fpath.t, string) result

get_b0_file provides an error message if b0_file is None.

Setup

Sourceval setup_with_cli : b0_dir:B0_std.Fpath.t option -> b0_file:B0_std.Fpath.t option -> cache_dir:B0_std.Fpath.t option -> code:B00_ocaml.Conf.code option -> hash_fun:(module B0_std.Hash.T) option -> jobs:int option -> log_level:B0_std.Log.level option -> no_pager:bool -> tty_cap:B0_std.Tty.cap option option -> unit -> (t, string) result

setup_with_cli determines and setups a configuration with the given values. These are expected to have been determined by environment variables and command line arugments.
