The ctags implementation from Universal Ctags (https://ctags.io/) is hopefully the best ctags alternative that works with e.g. vim. Remove the ctags binary from emacs so it does not conflict with this new package (the etags program remains for emacs to use).

|
|
# "Compilation of the C source files in the src directory produces an executable file called temacs, also called a
|
|
# bare impure Emacs. It contains the Emacs Lisp interpreter and I/O routines, but not the editing commands.
|
|
# The command temacs -l loadup would run temacs and direct it to load loadup.el. The loadup library loads additional Lisp libraries,
|
|
# which set up the normal Emacs editing environment. After this step, the Emacs executable is no longer bare.
|
|
# Because it takes some time to load the standard Lisp files, the temacs executable usually isn't run directly by users. Instead, as
|
|
# one of the last steps of building Emacs, the command 'temacs -batch -l loadup dump' is run. The special 'dump' argument causes temacs
|
|
# to dump out an executable program, called emacs, which has all the standard Lisp files preloaded. (The '-batch' argument prevents
|
|
# temacs from trying to initialize any of its data on the terminal, so that the tables of terminal information are empty in the dumped Emacs.)"
|
|
|
|
########## FROM src/Makefile:
|
|
## The dumped Emacs is as functional and more efficient than
|
|
## bootstrap-emacs, so we replace the latter with the former.
|
|
## Strictly speaking, emacs does not depend directly on all of $lisp,
|
|
## since not all pieces are used on all platforms. But DOC depends
|
|
## on all of $lisp, and emacs depends on DOC, so it is ok to use $lisp here.
|
|
# emacs$(EXEEXT): temacs$(EXEEXT) $(etc)/DOC $(lisp) $(leimdir)/leim-list.el
|
|
# if test "$(CANNOT_DUMP)" = "yes"; then \
|
|
# rm -f emacs$(EXEEXT); \
|
|
# ln temacs$(EXEEXT) emacs$(EXEEXT); \
|
|
# else \
|
|
# LC_ALL=C $(RUN_TEMACS) -batch -l loadup dump || exit 1; \
|
|
# test "X$(PAXCTL)" = X || $(PAXCTL) -zex emacs$(EXEEXT); \
|
|
# rm -f bootstrap-emacs$(EXEEXT); \
|
|
# ln emacs$(EXEEXT) bootstrap-emacs$(EXEEXT); \
|
|
# fi
|
|
|
|
# so emacs => temacs, and then it tries to execute emacs, leading to error
|
|
|
|
# We can build without dump, but a bootstrap-emacs is still needed to produce bytecode-compiled (platform-independent) emacs lisp .elc files.
