B0_envExecution environments.
This is notably what actions get access to.
Note. At some point we need a build/host distinction here.
val make :
b0_dir:B0_std.Fpath.t ->
build:B0_build.t ->
cwd:B0_std.Fpath.t ->
root_dir:B0_std.Fpath.t ->
scope_dir:B0_std.Fpath.t ->
tmake ~cwd ~scope_dir ~root_dir ~action is an execution context with given parameters. See corresponding accessors for semantics.
See also the relative file resolutions.
val b0_dir : t -> B0_std.Fpath.tb0_dir env is the b0 directory.
val cwd : t -> B0_std.Fpath.tcwd env is the absolute path to the current working directory.
val root_dir : t -> B0_std.Fpath.troot_dir env is the root directory.
val scope_dir : t -> B0_std.Fpath.tscope_dir env is the absolute path to the directory of the B0 file in which the action is defined or the root directory if the action is defined the global scope.
val scratch_dir : t -> B0_std.Fpath.tscratch_dir env is a shared scratch directory for actions in b0_dir. The directory must be created it may not exist, it's content may be destroyed at any time and actions are in charge of inventing a naming scheme to avoid collisions.
val unit_dir : t -> B0_unit.t -> B0_std.Fpath.tunit_dir env u is the build directory if u in the build build env. That is B0_build.build_dir (build env) u.
val in_root_dir : t -> B0_std.Fpath.t -> B0_std.Fpath.tin_scope_dir env p is Fpath.(root_dir env // p).
val in_scope_dir : t -> B0_std.Fpath.t -> B0_std.Fpath.tin_scope_dir env p is Fpath.(scope_dir env // p).
val in_scratch_dir : t -> B0_std.Fpath.t -> B0_std.Fpath.tin_scope_dir env p is Fpath.(scratch_dir env // p).
val in_unit_dir : t -> B0_unit.t -> B0_std.Fpath.t -> B0_std.Fpath.tin_unit_dir env u p is Fpath.(unit_build_dir env // p).
val build : t -> B0_build.tbuild env is the current build (if any).
