B0 definitions.
B0 definitions are uniquely named OCaml values of different types used for describing software construction. The value names are used for end-user interaction.
B0 definitions occur in various B0 files and libraries during the module initialisation phase of the program consuming the definitions. After the module initialisation phase no new definition is allowed.
This module handle the management of these named values in B0 files and libraries. It provides the infrastructure to track the location of their definition, properly scope the names, check their unicity in the scope, index them and make sure they cannot be defined after the module initialisation phase of the program.
module Scope : sig ... endScopes are used to track and scope B0 definitions created by libraries and B0 files.
val file : t -> B0_std.Fpath.t optionfile d is the absolute file path in which d is defined, if defined in a file.
val scope_dir : t -> B0_std.Fpath.t optionscope_dir is the parent of file d.
val name : t -> stringname d is the qualified name of d.
val doc : t -> stringdoc d is a one-line documentation string for d.
Exception thrown if a definition error occurs. This can be due to
The argument is an error message to print as is. The backtrace should point to the redefinition (it is unfortunately difficult to keep track of the previous definition).
module type VALUE = sig ... endThe type for values to be named.
module type S = sig ... endThe type of named values.
