This command uses opam state to output information on how to use installed libraries, updating the user’s $PATH, and substitute variables used in opam packages. Apart from opam config -env, most of these commands are used by opam internally, and thus are of limited interest for the user.
-env
: Set the environment variables PATH, MANPATH, OCAML_TOPLEVEL_PATH
and CAML_LD_LIBRARY_PATH according to the current selected
compiler. The output of this command is meant to be evaluated by a
shell, for example by doing eval opam config -env.
-list-vars : Return the list of all variables defined in installed packages.
-var <var> : Return the value associated with variable <var>
-subst <filename>... : Substitute variables in file <filename>.in to create <filename>
-I <name>...
: Return the list of paths to include when compiling a project using the package <name>. Using the -r option will take into account the transitive closure of dependencies.
-bytecomp|-asmcomp|-bytelink|-asmlink <name>[.<lib>]... : Return the associated value for section <lib> in the config file for package <name>.
