Since the location of those files changes between build time and installation time, this requires to tweak the file name used in those (#$ . NNN) references during the dump so they don't hardcode the build directory. We do it in the same way as was already done for those same file names in `load-history`, except we convert them back to absolute file names more lazily (i.e. when fetching the actual docstring rather than at startup), which requires remembering the `lisp-dir` computed at startup in the new `lisp-directory` variable. * src/Makefile.in ($(etc)/DOC): Don't scan Lisp files any more. * src/lread.c (Fload): Use relative file names for `load-file-name` when preloading for the dump, like we already did for `current-load-list`. (read_list): Don't zero-out dynamic docstring references during the preload since they won't be filled later by Snarf-documentation any more. (read1): Remove the hash-hack for doc references that were zeroed. * lisp/startup.el (lisp-directory): New variable. (command-line): Set it. * src/doc.c (get_doc_string): Use `lisp-directory` for dynamic docstring references using relative file names. (syms_of_doc): Add `Qlisp_directory`. * lib-src/make-docfile.c (scan_file): Don't handle `.el` or `.elc` files any more. (IS_SLASH): Remove macro, not used any more. (skip_white, read_lisp_symbol, search_lisp_doc_at_eol) (scan_lisp_file): Remove functions, not used any more. * doc/lispref/loading.texi (Library Search): Mention `lisp-directory`. |
