Tool spawns

type stdo = [ `File of B0_std.Fpath.t | `Tee of B0_std.Fpath.t | `Ui ] 
The type for spawn standard outputs redirections.
type success_exits = int list 
The list of process exit codes that indicate success. If the list is empty this any exit code.
type t 
The type for process spawn operations.
val env : t -> B0_std.Os.Env.assignments
env s is the environment in which s runs.
val relevant_env : t -> B0_std.Os.Env.assignments
relevant_env s are the assignements of env s that should be taken into account for caching.
val cwd : t -> B0_std.Fpath.t
cwd s is the cwd with which s runs.
val stdin : t -> B0_std.Fpath.t option
stdin s is the file s uses as stdin (if any).
val stdout : t -> stdo
stdout s is the redirection s uses for stdout.
val stderr : t -> stdo
stderr s is the redirection s uses for stderr.
val success_exits : t -> success_exits
success_exits s is the list of process exit codes s that indicate success.
val tool : t -> B0_std.Cmd.tool
tool t is the spawned tool. Note that this has to be a full path at that point.
val args : t -> B0_std.Cmd.t
args s are the spawned tool arguments.
val stdo_ui : t -> (string, string) Pervasives.result option
stdo_ui sr is the standard outputs redirection contents of s once it has executed (if any).
val set_stdo_ui : t -> (string, string) Pervasives.result option -> unit
set_stdo_ui w ui sets w's standard output redirection contents to ui.
val result : t -> (B0_std.Os.Cmd.status, string) Pervasives.result
result s is the spawn result of s.
val set_result : t -> (B0_std.Os.Cmd.status, string) Pervasives.result -> unit
set_result s e the spawn result of s to e.


val pp_success_exits : int list B0_std.Fmt.t
pp_success_exits formats the success exits.
val pp_cmd : t B0_std.Fmt.t
pp_cmd formats the command issued by the spawn.
val pp_stdo_ui : elide:bool -> t B0_std.Fmt.t
pp_stdo_ui formats the standard output ui of the spawn. If elide is true elides long outputs.
val pp_result : (B0_std.Os.Cmd.status, string) Pervasives.result B0_std.Fmt.t
pp_result formats the command status of the spawn.
val pp : t B0_std.Fmt.t
pp formats a spawn.
