NAME

       clisp-link - link a new external module to CLISP[1].

SYNOPSIS

       clisp-link [create] [module] [file...]

       clisp-link [add] [source] [destination] [module...]

       clisp-link [run] [source] [module...]

       clisp-link [install] [module...]

DESCRIPTION

       This shell script operates on CLISP[1] module sets and linking sets:

       •   creates new module sets out of source files

       •   adds module sets to a linking set to produce a new linking set

       •   runs CLISP[1] with module sets added

       •   Only in CLISP[1] built without configure flag --without-dynamic-modules.

           installs new module sets for general use

OPTIONS

       create
           The command

               $ clisp-link create module file ...

           creates a module set in module directory which refers (via symbolic links) to files
           file... The files are expected to be modules of their own.

       add
           The command

               $ clisp-link add source destination module ...

           combines the linking set in directory source and the modules in directories module...
           to a new linking set, in the directory destination which is newly created.

       run
           The command

               $ clisp-link run source module ...

           runs the linking set in directory source, with the modules in directories module...
           Unless CLISP[1] has been built with the configuration option
           --without-dynamic-modules, the loading will be performed using SYS::DYNLOAD-MODULES.
           Otherwise - this is much slower - a temporary linking set will be created and deleted
           afterwards.

       install
           Only in CLISP[1] built without configure flag --without-dynamic-modules.

           The command

               $ clisp-link install module ...

           installs the modules in directories module... into CUSTOM:*LIB-DIRECTORY* or, if it is
           not writable to the user (e.g., if a system-wide CLISP[1] installation is used and the
           user does not have administrative privileges), into CUSTOM:*USER-LIB-DIRECTORY*.

           Variable CUSTOM:*USER-LIB-DIRECTORY* is initially set to (MERGE-PATHNAMES[2] ".clisp/"
           (USER-HOMEDIR-PATHNAME[3])) if that directory exists, and can be reset in the RC file.

               Note
               Do not add CUSTOM:*USER-LIB-DIRECTORY* to CUSTOM:*LOAD-PATHS* or under any element
               thereof. Use REQUIRE instead of LOAD to load dynamic modules.
           For this command to work, each module directory must contain a Makefile with a
           clisp-module-distrib target which uses LN to distribute the files necessary to run the
           module into destdir. This is in addition to the general requirement that link.sh is
           present.

EXAMPLES

       See Section 32.2.6, “Example”.

FILES

       clisp-link needs a “link kit” directory containing:

       •   "modules.c"

       •   "clisp.h"

       clisp-link expects to find these files in a subdirectory linkkit/ of the installation
       directory (i.e., CUSTOM:*LIB-DIRECTORY*) which it acquires by running

           $ `dirname $0`/clisp -b

       This can be overridden by the environment variable[4] CLISP_LINKKIT.
