Reduce regexp usage, now CL-oriented non-regexp code available, core Lisp
lisp/ChangeLog addition:
2015-04-01 Aidan Kehoe <kehoea@parhasard.net>
When calling #'string-match with a REGEXP without regular
expression special characters, call #'search, #'mismatch, #'find,
etc. instead, making our code less likely to side-effect other
functions' match data and a little faster.
* apropos.el (apropos-command):
* apropos.el (apropos):
Call (position ?\n ...) rather than (string-match "\n" ...) here.
* buff-menu.el:
* buff-menu.el (buffers-menu-omit-invisible-buffers):
Don't fire up the regexp engine just to check if a string starts
with a space.
* buff-menu.el (select-buffers-tab-buffers-by-mode):
Don't fire up the regexp engine just to compare mode basenames.
* buff-menu.el (format-buffers-tab-line):
* buff-menu.el (build-buffers-tab-internal): Moved to being a
label within the following.
* buff-menu.el (buffers-tab-items): Use the label.
* bytecomp.el (byte-compile-log-1):
Don't fire up the regexp engine just to look for a newline.
* cus-edit.el (get):
Ditto.
* cus-edit.el (custom-variable-value-create):
Ditto, but for a colon.
* descr-text.el (describe-text-sexp):
Ditto.
* descr-text.el (describe-char-unicode-data):
Use #'split-string-by-char given that we're just looking for a
semicolon.
* descr-text.el (describe-char):
Don't fire up the regexp engine just to look for a newline.
* disass.el (disassemble-internal):
Ditto.
* files.el (file-name-sans-extension):
Implement this using #'position.
* files.el (file-name-extension):
Correct this function's docstring, implement it in terms of
#'position.
* files.el (insert-directory):
Don't fire up the regexp engine to split a string by space; don't
reverse the list of switches, this is actually a longstand bug as
far as I can see.
* gnuserv.el (gnuserv-process-filter):
Use #'position here, instead of consing inside #'split-string
needlessly.
* gtk-file-dialog.el (gtk-file-dialog-update-dropdown):
Use #'split-string-by-char here, don't fire up #'split-string for
directory-sep-char.
* gtk-font-menu.el (hack-font-truename):
Implement this more cheaply in terms of #'find,
#'split-string-by-char, #'equal, rather than #'string-match,
#'split-string, #'string-equal.
* hyper-apropos.el (hyper-apropos-grok-functions):
* hyper-apropos.el (hyper-apropos-grok-variables):
Look for a newline using #'position rather than #'string-match in
these functions.
* info.el (Info-insert-dir):
* info.el (Info-insert-file-contents):
* info.el (Info-follow-reference):
* info.el (Info-extract-menu-node-name):
* info.el (Info-menu):
Look for fixed strings using #'position or #'search as appropriate
in this file.
* ldap.el (ldap-decode-string):
* ldap.el (ldap-encode-string):
#'encode-coding-string, #'decode-coding-string are always
available, don't check if they're fboundp.
* ldap.el (ldap-decode-address):
* ldap.el (ldap-encode-address):
Use #'split-string-by-char in these functions.
* lisp-mnt.el (lm-creation-date):
* lisp-mnt.el (lm-last-modified-date):
Don't fire up the regexp engine just to look for spaces in this file.
* menubar-items.el (default-menubar):
Use (not (mismatch ...)) rather than #'string-match here, for
simple regexp.
Use (search "beta" ...) rather than (string-match "beta" ...)
* menubar-items.el (sort-buffers-menu-alphabetically):
* menubar-items.el (sort-buffers-menu-by-mode-then-alphabetically):
* menubar-items.el (group-buffers-menu-by-mode-then-alphabetically):
Don't fire up the regexp engine to check if a string starts with
a space or an asterisk.
Use the more fine-grained results of #'compare-strings; compare
case-insensitively for the buffer menu.
* menubar-items.el (list-all-buffers):
* menubar-items.el (tutorials-menu-filter):
Use #'equal rather than #'string-equal, which, in this context,
has the drawback of not having a bytecode, and no redeeming
features.
* minibuf.el:
* minibuf.el (un-substitute-in-file-name):
Use #'count, rather than counting the occurences of $ using the
regexp engine.
* minibuf.el (read-file-name-internal-1):
Don't fire up the regexp engine to search for ?=.
* mouse.el (mouse-eval-sexp):
Check for newline with #'find.
* msw-font-menu.el (mswindows-reset-device-font-menus):
Split a string by newline with #'split-string-by-char.
* mule/japanese.el:
* mule/japanese.el ("Japanese"):
Use #'search rather than #'string-match; canoncase before
comparing; fix a bug I had introduced where I had been making case
insensitive comparisons where the case mattered.
* mule/korea-util.el (default-korean-keyboard):
Look for ?3 using #'find, not #'string-march.
* mule/korea-util.el (quail-hangul-switch-hanja):
Search for a fixed string using #'search.
* mule/mule-cmds.el (set-locale-for-language-environment):
#'position, #'substitute rather than #'string-match,
#'replace-in-string.
* newcomment.el (comment-make-extra-lines):
Use #'search rather than #'string-match for a simple string.
* package-get.el (package-get-remote-filename):
Use #'position when looking for ?@
* process.el (setenv):
* process.el (read-envvar-name):
Use #'position when looking for ?=.
* replace.el (map-query-replace-regexp):
Use #'split-string-by-char instead of using an inline
implementation of it.
* select.el (select-convert-from-cf-text):
* select.el (select-convert-from-cf-unicodetext):
Use #'position rather than #'string-match in these functions.
* setup-paths.el (paths-emacs-data-root-p):
Use #'search when looking for simple string.
* sound.el (load-sound-file):
Use #'split-string-by-char rather than an inline reimplementation
of same.
* startup.el (splash-screen-window-body):
* startup.el (splash-screen-tty-body):
Search for simple strings using #'search.
* version.el (emacs-version):
Ditto.
* x-font-menu.el (hack-font-truename):
Implement this more cheaply in terms of #'find,
#'split-string-by-char, #'equal, rather than #'string-match,
#'split-string, #'string-equal.
* x-font-menu.el (x-reset-device-font-menus-core):
Use #'split-string-by-char here.
* x-init.el (x-initialize-keyboard):
Search for a simple string using #'search.

This file exists only because VC++ lacks pragmas that let you change the default calling convention in the middle of a file. With optimization, we compile XEmacs using fastcall as the default convention; but libraries are not compiled this way, and thus need __cdecl in their declaration. Without the pragma, we either (a) depend on libraries that declare their external functions with suitable preprocessor definitions that we can change; (b) force the user to recompile the library with fastcall (not reasonable); (c) hack the headers manually (not reasonable); (d) put all calls to the library in a separate file where the default calling convention is __cdecl (hence, this file). In fact, some libraries do make (a) feasible. This is the case with PNG and ZLIB. JPEG almost does so, since all externs are wrapped with EXTERN(); but they fail to wrap their definition of EXTERN with #ifndef EXTERN, so we can't override it. XPM is similar, wrapping their externs with FUNC() -- again, not overridable. With PNG, we define PNG_EXPORT; with ZLIB, we define ZEXPORT and ZEXPORTVA. */ #ifdef HAVE_XPM void qxe_XpmFreeXpmImage (XpmImage *image) { XpmFreeXpmImage (image); } void qxe_XpmFreeXpmInfo (XpmInfo *info) { XpmFreeXpmInfo (info); } int qxe_XpmCreateXpmImageFromBuffer (char *buffer, XpmImage *image, XpmInfo *info) { return XpmCreateXpmImageFromBuffer (buffer, image, info); } void qxe_XpmFree (void *ptr) { XpmFree (ptr); } int qxe_XpmReadFileToData (char *filename, char ***data_return) { return XpmReadFileToData (filename, data_return); } #endif /* HAVE_XPM */ #ifdef HAVE_JPEG boolean qxe_jpeg_finish_decompress (j_decompress_ptr cinfo) { return jpeg_finish_decompress (cinfo); } boolean qxe_jpeg_start_decompress (j_decompress_ptr cinfo) { return jpeg_start_decompress (cinfo); } JDIMENSION qxe_jpeg_read_scanlines (j_decompress_ptr cinfo, JSAMPARRAY scanlines, JDIMENSION max_lines) { return jpeg_read_scanlines (cinfo, scanlines, max_lines); } int qxe_jpeg_read_header (j_decompress_ptr cinfo, boolean require_image) { return jpeg_read_header (cinfo, require_image); } void qxe_jpeg_CreateDecompress (j_decompress_ptr cinfo, int version, size_t structsize) { jpeg_CreateDecompress (cinfo, version, structsize); } struct jpeg_error_mgr * qxe_jpeg_std_error (struct jpeg_error_mgr *err) { return jpeg_std_error (err); } void qxe_jpeg_destroy_decompress (j_decompress_ptr cinfo) { jpeg_destroy_decompress (cinfo); } boolean qxe_jpeg_resync_to_restart (j_decompress_ptr cinfo, int desired) { return jpeg_resync_to_restart (cinfo, desired); } #endif /* HAVE_JPEG */ #ifdef HAVE_TIFF tdata_t qxe_TIFFmalloc (tsize_t x1) { return _TIFFmalloc (x1); } void qxe_TIFFfree (tdata_t x1) { _TIFFfree (x1); } void qxe_TIFFClose (TIFF *x1) { TIFFClose (x1); } int qxe_TIFFGetField (TIFF *x1, ttag_t x2, uint32 *x3) { return TIFFGetField (x1, x2, x3); } TIFF * qxe_TIFFClientOpen (const char *x1, const char *x2, thandle_t x3, TIFFReadWriteProc x4, TIFFReadWriteProc x5, TIFFSeekProc x6, TIFFCloseProc x7, TIFFSizeProc x8, TIFFMapFileProc x9, TIFFUnmapFileProc x10) { return TIFFClientOpen (x1, x2, x3, x4, x5, x6, x7, x8, x9, x10); } TIFFErrorHandler qxe_TIFFSetErrorHandler (TIFFErrorHandler x1) { return TIFFSetErrorHandler (x1); } TIFFErrorHandler qxe_TIFFSetWarningHandler (TIFFErrorHandler x1) { return TIFFSetWarningHandler (x1); } int qxe_TIFFReadRGBAImage (TIFF *x1, uint32 x2, uint32 x3, uint32 *x4, int x5) { return TIFFReadRGBAImage (x1, x2, x3, x4, x5); } #endif /* HAVE_TIFF */
