Module Topfind

Load packages from toploops and scripts * * The Topfind module is part of the findlib package. The module * depends on the presence of a toploop. When building a toploop, it is * automatically linked in if "findlib" is linked in, e.g. *

* ocamlfind ocamlmktop ...options... -package findlib -linkpkg 
* 

* * When the platform supports DLLs, another possibility to get a toploop * with findlib directives is to load the file "topfind" (normally installed * in the standard library directory): *

* $ ocaml
*         Objective Caml version 3.04
* # #use "topfind";;
* Findlib has been successfully loaded. Additional directives:
*   #require "package";;      to load a package
*   #list;;                   to list the available packages
*   #camlp4o;;                to load camlp4 (standard syntax)
*   #camlp4r;;                to load camlp4 (revised syntax)
*   Topfind.reset();;         to force that packages will be reloaded
* ~ : unit = ()
* # _
* 

* * This works even in scripts (but the startup message is suppressed in this * case). * * The module is not thread-safe; if used in a multi-threaded script, all * packgage loading must have happened before the first thread forks. * * The Topfind module contains some functions simplifying package loading * in scripts. Most important, there is a new directive #require for * the same purpose (see below). * * The Topfind module needs some initialization, in particular the * predicates variable needs to be * set, and the packages already compiled into the toploop needs to be * declared by the don't_load * function. If the toploop has been built by ocamlfind, * the necessary initialization is * automatically compiled in.
