In my ~/.ocamlinit, I have some directives:
#use "topfind"
#thread
#require "core.top"
As a result, every time the OCaml toplevel (i.e. ocaml) starts, I get this huge wall of text:
OCaml version 4.02.3
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)
#predicates "p,q,...";; to set these predicates
Topfind.reset();; to force that packages will be reloaded
#thread;; to enable threads

Is there a way to silence the loading of modules when the toplevel starts?
trivelt's comment has the best answer - use utop! - but if you or others want to use ocaml directly you can set Sys.interactive to false to silence most of the status messages. For example:
Noisy:
$ ocaml
OCaml version 4.06.0
# #use "topfind";;
- : unit = ()
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)
#predicates "p,q,...";; to set these predicates
Topfind.reset();; to force that packages will be reloaded
#thread;; to enable threads
- : unit = ()
Quieter:
$ ocaml
OCaml version 4.06.0
# Sys.interactive := false;;
- : unit = ()
# #use "topfind";;
- : unit = ()
- : unit = ()
You can put Sys.interactive := false;; at the start of your .ocamlinit file and Sys.interactive := true;; at the end if you want to have this work automatically.
