[xemacs-hg @ 2003-02-14 09:50:15 by ben] syntax-table fixes 1. the updating of mirror tables every time a syntax table was modified was taking up huge amounts of time so i added a dirty flag and made the updating "just-in-time". 2. no-longer-used char-table-entries were not getting "freed", generating tons of garbage. 3. syntax_match() was being incorrectly called on mirror tables in the cache, not the original syntax table. buffer.c, syntax.c: Move syntax table description from buffer.c to syntax.c. chartab.c, chartab.h: Free extra char table entries to avoid excessive garbage. Add flags for dirty and mirror_table_p to char tables. Add a back pointer from mirror tables to the original syntax table. When modifying a syntax table, don't update the mirror table right away, just mark as dirty. Add various asserts to make sure we are dealing with the right type of table (mirror or non-mirror). font-lock.c, syntax.c, syntax.h: Add entry to syntax caches for the non-mirror table. Set it appropriately when initializing the syntax table. Use it, not the mirror table, for calls to syntax_match(). Don't create a bogus float each time, just once at startup. Add some asserts, as in chartab.c. syntax.h: When retrieving the syntax code, check the dirty flag and update the mirror tables as appropriate. Add some asserts, as above.

### Commentary:

## This file copies a single lisp file into an XEmacs package hierarchy and
## performs the necessary magic so that it will be autoloaded at the next
## dump.

## Parameters:
##	$1 -- Full path to an XEmacsen later than 20.3
##	$2 -- Full path to a lisp package tarball to install
##	$3 -- Full path to a lisp directory in an XEmacs package hierarchy
##	      This directory will be created if it does not exist.
##	      NOTE: the directory name should *not* end in a trailing slash


### Code:

XEMACS="$1"			# Not used at present
LISP_FILE="$2"			# Should be a binary package tarball
DEST_DIR="$3"			# Should be a top level package directory

# Test for valid XEmacs executable and valid input file
if [ ! -f "${LISP_FILE}" -o ! -x "${XEMACS}" ]; then
	exit 1
fi

# Test for destination directory, creating if necessary
test -d "${DEST_DIR}" || mkdir "${DEST_DIR}"
test -d "${DEST_DIR}" || exit 1;

# Very simple minded extraction for the first cut
# We'll get more sophisticated later
cd "${DEST_DIR}"
gunzip -c "${LISP_FILE}" | tar xvf -

# Need to refresh the info/dir file, I don't know how to do that.

exit 0
