val exec_cwd : (build -> t -> B0_std.Fpath.t B0_std.Fut.t) B0_meta.keyexec_cwd is a function to determine a current working directory for exec actions.
val scope_cwd : build -> t -> B0_std.Fpath.t B0_std.Fut.tscope_cwd is function that determines the unit's scope.
val exec_env :
(build -> t -> B0_std.Os.Env.assignments B0_std.Fut.t) B0_meta.keyexec_env is a function to determine an environement for exec actions.
val exec : actionexec is an action that B0_std.Os.Exit.exec's a unit's outcome as follows:
B0_meta.exe_file.B0_std.Fpath.basename of B0_meta.exe_file as the program name and the action's args as arguments.exec_cwd, it is used to determine the cwd otherwise the default of B0_std.Os.Exit.exec is used.exec_env, it is used to determine the environment otherwise the default B0_std.Os.Exit.exec is used.val exec_file :
build ->
t ->
B0_std.Fpath.t ->
B0_std.Cmd.t ->
B0_std.Os.Exit.t B0_std.Fut.texec_file u file argv is a B0_std.Os.Exit.exec with file and argv and:
u defines exec_cwd, it is used to determine the cwd otherwise the default of B0_std.Os.Exit.exec is used.u defines exec_env, it is used to determine the environment otherwise the default B0_std.Os.Exit.exec is used.
