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.

! copy and modify any of the resources below into your own ~/.Xresources file.
! .Xresources specifies defaults for all applications, not just XEmacs; it is

! 


! Colors and backgrounds.
! ======================
! The contrasts of these colors will cause them to map to the appropriate
! one of "black" or "white" on monochrome systems.
! 
! The valid color names on your system can be found by looking in the file
! `rgb.txt', usually found in /usr/X11R6/lib/X11/ or /usr/openwin/lib/X11/.

! Set the foreground and background colors of the `default' face.
! The default face colors are the base for most of the other faces'
! colors.  The default background is gray80, and the default foreground
! is black.
XEmacs.default.attributeBackground: gray80
! XEmacs.default.attributeForeground: black

! Set the modeline colors.
XEmacs.modeline*attributeForeground:	Black
XEmacs.modeline*attributeBackground:	Gray75

! Set the color of the text cursor.
XEmacs.text-cursor*attributeBackground:	Red3

! If you want to set the color of the mouse pointer, do this:
! XEmacs.pointer*attributeForeground:	Black
! If you want to set the background of the mouse pointer, do this:
! XEmacs.pointer*attributeBackground:	White
! Note that by default, the pointer foreground and background are the same
! as the default face.

! Set the menubar colors.  This overrides the default foreground and
! background colors specified above.
XEmacs*menubar*Foreground:		Gray30
XEmacs*menubar*Background:		Gray75
! This is for buttons in the menubar.  
! Yellow would be better, but that would map to white on monochrome.
XEmacs*menubar.buttonForeground:		Blue
XEmacs*XlwMenu.selectColor:		ForestGreen
XEmacs*XmToggleButton.selectColor:	ForestGreen

! Specify the colors of popup menus.
XEmacs*popup*Foreground:			Black
XEmacs*popup*Background:			Gray75

! Specify the colors of the various sub-widgets of the dialog boxes.
XEmacs*dialog*Foreground:		Black
! #A5C0C1 is a shade of blue
XEmacs*dialog*Background:		#A5C0C1
! The following three are for Motif dialog boxes ...
XEmacs*dialog*XmTextField*Background:	WhiteSmoke
XEmacs*dialog*XmText*Background:		WhiteSmoke
XEmacs*dialog*XmList*Background:		WhiteSmoke
! While this one is for Athena dialog boxes.
XEmacs*dialog*Command*Background:	WhiteSmoke

! Athena dialog boxes are sometimes built with the Xaw3d
! variant of the Athena toolkit.
! XEmacs being nice to 8bit displays, it defaults to:
XEmacs*dialog*Command*beNiceToColormap:	true
! If you are shocked by the ugliness of the 3d rendition,
! you may want to set (even on 8bit displays) the above to false.

! Xlw Scrollbar colors
XEmacs*XlwScrollBar.Foreground:		Gray30
XEmacs*XlwScrollBar.Background:		Gray75
XEmacs*XmScrollBar.Foreground:		Gray30
XEmacs*XmScrollBar.Background:		Gray75

!
! The Lucid Scrollbar supports two added resources, SliderStyle is either
! "plain" (default) or "dimple".  Dimple puts a small dimple in the middle
! of the slider that depresses when the slider is clicked on.  ArrowPosition is
! either "opposite" (default) or "same".  Opposite puts the arrows at opposite
! of the scrollbar, same puts both arrows at the same end, like the Amiga.
!
! XEmacs*XlwScrollBar.SliderStyle:    dimple
! XEmacs*XlwScrollBar.ArrowPosition:  opposite


!
! If you want to turn off a toolbar, set its height or width to 0.
! The correct size value is not really arbitrary.  We only control it
! this way in order to avoid excess frame resizing when turning the
! toolbars on and off.
!
! To change the heights and widths of the toolbars:
!
! XEmacs.topToolBarHeight:		37
! XEmacs.bottomToolBarHeight:		0
! XEmacs.leftToolBarWidth:		0
! XEmacs.rightToolBarWidth:		0

XEmacs*topToolBarShadowColor:		Gray90
XEmacs*bottomToolBarShadowColor:		Gray40
XEmacs*backgroundToolBarColor:		Gray75
XEmacs*toolBarShadowThickness:		2


! If you want to turn off vertical scrollbars, or change the default
! pixel width of the vertical scrollbars, do it like this (0 width
! means no vertical scrollbars):
! 
! XEmacs.scrollBarWidth: 0
! 
! To change it for a particular frame, do this:
! 
! XEmacs*FRAME-NAME.scrollBarWidth: 0


! If you want to turn off horizontal scrollbars, or change the default
! pixel height of the horizontal scrollbars, do it like this (0 height
! means no horizontal scrollbars):
! 
! XEmacs.scrollBarHeight: 0
! 
! To change it for a particular frame, do this:
! 
! XEmacs*FRAME-NAME.scrollBarHeight: 0


! To dynamically change the labels used for menubar buttons...
! 
! XEmacs*XlwMenu.resourceLabels: True
! XEmacs*XlwMenu.newFrame.labelString: Open Another Window

! To have the Motif scrollbars on the left instead of the right, do this:
! 
! XEmacs*scrollBarPlacement: BOTTOM_LEFT
!
! To have the Athena scrollbars on the right, use `BOTTOM_RIGHT' instead

! To have Motif scrollbars act more like Xt scrollbars...
!
! XEmacs*XmScrollBar.translations: #override \n\
!     <Btn1Down>:     PageDownOrRight(0)    \n\
!     <Btn3Down>:     PageUpOrLeft(0)

! Fonts.
! ======
! XEmacs requires the use of XLFD (X Logical Font Description) format font
! names, which look like
! 
! 	*-courier-medium-r-*-*-*-120-*-*-*-*-*-*
! 
! if you use any of the other, less strict font name formats, some of which
! look like
! 		lucidasanstypewriter-12
! and		fixed
! and		9x13
! 
! then XEmacs won't be able to guess the names of the bold and italic versions.
! All X fonts can be referred to via XLFD-style names, so you should use those
! forms.  See the man pages for X(1), xlsfonts(1), and xfontsel(1).


! The default font for the text area of XEmacs is chosen at run-time
! by lisp code which tries a number of different possibilities in order
! of preference.  If you wish to override it, use this:
! 
! XEmacs.default.attributeFont:  -*-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-*

! If you choose a font which does not have an italic version, you can specify
! some other font to use for it here:
! 
! XEmacs.italic.attributeFont:  -*-courier-medium-o-*-*-*-120-*-*-*-*-iso8859-*
! 
! If you choose a font which does not have a bold-italic version,
! you can specify some other font to use for it here:
! 
! XEmacs.bold-italic.attributeFont:  -*-courier-bold-o-*-*-*-120-*-*-*-*-iso8859-*
! 
! And here is how you would set the background color of the `highlight' face,
! but only on the screen named `debugger':
! 
! XEmacs*debugger.highlight.attributeBackground:		PaleTurquoise
! 
! See the NEWS file (C-h n) for a more complete description of the resource
! syntax of faces.


! Font of the modeline, menubar and pop-up menus.
! Note that the menubar resources do not use the `face' syntax, since they
! are X toolkit widgets and thus outside the domain of XEmacs proper.
! 
! When X Font Sets are enabled with ./configure --with-xfs (eg, for
! multilingual menubars and XIM), some .font resources (those specific to
! the Lucid widget set) are ignored in favor of .fontSet resources.
! Note that you need to use fontSet (or FontSet) in that case even if you
! want to specify one font:
!
! *menubar*FontSet:	-*-helvetica-bold-r-*-*-*-120-*-*-*-*-iso8859-*
!
! There is no harm in having both resources set, except for the confusion
! you suffer.  Sorry; that's the price of backward compatibility.
!
*menubar*Font:		-*-helvetica-bold-r-*-*-*-120-*-*-*-*-iso8859-*
*popup*Font:		-*-helvetica-bold-r-*-*-*-120-*-*-*-*-iso8859-*
*menubar*FontSet:	-*-helvetica-bold-r-*-*-*-120-*-*-*-*-iso8859-*, \
			-*-*-*-*-*-*-*-120-*-iso10646-1, \
			-*-*-*-*-*-*-*-120-*-jisx0208.1983-0, \
			-*-*-*-*-*-*-*-120-*-jisx0201.1976-0
*popup*FontSet:		-*-helvetica-bold-r-*-*-*-120-*-*-*-*-iso8859-*, \
			-*-*-*-*-*-*-*-120-*-iso10646-1, \
			-*-*-*-*-*-*-*-120-*-jisx0208.1983-0, \
			-*-*-*-*-*-*-*-120-*-jisx0201.1976-0

! Font in the Motif dialog boxes.
! (Motif uses `fontList' while most other things use `font' - if you don't
! know why you probably don't want to.)
! 
XEmacs*XmDialogShell*FontList:	-*-helvetica-bold-r-*-*-*-120-*-*-*-*-iso8859-*
XEmacs*XmTextField*FontList:	-*-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-*
XEmacs*XmText*FontList:		-*-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-*
XEmacs*XmList*FontList:		-*-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-*

! Font in the Athena dialog boxes.
! I think 14-point looks nicer than 12-point.
! Some people use 12-point anyway because you get more text, but
! there's no purpose at all in doing this for dialog boxes.

XEmacs*Dialog*Font:		-*-helvetica-bold-r-*-*-*-140-*-*-*-*-iso8859-*

! Dialog box translations.
! =======================

! This accelerator binds <return> in a dialog box to <activate> on button1
XEmacs*dialog*button1.accelerators:#override\
<KeyPress>Return: ArmAndActivate()\n\
<KeyPress>KP_Enter: ArmAndActivate()\n\
Ctrl<KeyPress>m: ArmAndActivate()\n

! Translations to make the TextField widget behave more like XEmacs
XEmacs*XmTextField.translations: #override\n\
	!<Key>osfBackSpace:	delete-previous-character()\n\

	<Btn2Up>:		copy-primary()\n

! With the XEmacs typeahead it's better to not have space be bound to
! ArmAndActivate() for buttons that appear in dialog boxes.  This is
! not 100% Motif compliant but the benefits far outweight the
! compliancy problem.
