Conf (b0.B0_driver.Conf)

Default file names

val b0_file_name : string

b0_file_name is "B0.ml" the default b0 file name.

val drivers_dir_name : string

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

Configurations

type t

The type for configurations.

val make : 
  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:B0_ocaml.Code.t option ->
  env:B0_std.Os.Env.t ->
  hash_fun:(module B0_std.Hash.T) ->
  jobs:int ->
  log_level:B0_std.Log.level ->
  no_pager:bool ->
  fmt_styler:B0_std.Fmt.styler ->
  unit ->
  t

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

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

b0_file is the absolute path to the b0 file (if any).

val b0_dir : t -> B0_std.Fpath.t

b0_dir is the absolute path to the b0 directory.

val cache_dir : t -> B0_std.Fpath.t

cache_dir is the absolute path to the cache directory.

val cwd : t -> B0_std.Fpath.t

cwd is the absolute path to the current working directory.

val code : t -> B0_ocaml.Code.t option

code is the code to which the driver is compiled.

val env : t -> B0_std.Os.Env.t

env is the process environment of the driver.

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

hash_fun is the hash function to use for build caching.

val jobs : t -> int

jobs is the maximal number of spawns allowed.

val log_level : t -> B0_std.Log.level

log_level is the desired log level.

val memo : t -> (B0_memo.t, string) Stdlib.result

memo is the memoizer for the configuration.

val no_pager : t -> bool

no_pager indicates no paging is desired on stdout.

val fmt_styler : t -> B0_std.Fmt.styler

fmt_styler is the styler to assume for outputs.

Derived data

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

get_b0_file provides an error message if b0_file is None.

Setup

val 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:B0_ocaml.Code.t option ->
  hash_fun:(module B0_std.Hash.T) option ->
  jobs:int option ->
  log_level:B0_std.Log.level option ->
  no_pager:bool ->
  color:B0_std.Fmt.styler option option ->
  unit ->
  (t, string) Stdlib.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.
