The +menu at the extreme right is the `Help' menu, which should always be +available. It provides access to all the XEmacs help facilities +available through `C-h', as well as samples of various configuration +files like `~/.Xdefaults' and `~/.emacs'. At the extreme left is the +`Files' menu, which provides the usual file reading, writing, and +printing operations, as well as operations like revert buffer from most +recent save. The next menu from the left is the `Edit' menu, which +provides the `Undo' operation as well as cutting and pasting, +searching, and keyboard macro definition and execution. + + XEmacs provides a very dynamic environment, and the Lisp language +makes for highly flexible applications. The menubar reflects this: +many menus (eg, the `Buffers' menu, *note Buffers Menu::) contain items +determined by the current state of XEmacs, and most major modes and many +minor modes add items to menus and even whole menus to the menubar. In +fact, some applications like w3.el and VM provide so many menus that +they define a whole new menubar and add a button that allows convenient +switching between the "XEmacs menubar" and the "application menubar". +Such applications normally bind themselves to a particular frame, and +this switching only takes place on frames where such an application is +active (ie, the current window of the frame is displaying a buffer in +the appropriate major mode). + + Other menus which are typically available are the `Options', +`Tools', `Buffers', `Apps', and `Mule' menus. For detailed +descriptions of these menus, *Note Pull-down Menus::. (In 21.2 +XEmacsen, the `Mule' menu will be moved under `Options'.) + + +File: xemacs.info, Node: Scrollbar Basics, Next: Toolbar Basics, Prev: Menubar Basics, Up: GUI Components + +XEmacs Scrollbars +================= + + XEmacs scrollbars provide the usual interface. Arrow buttons at +either end allow for line by line scrolling, including autorepeat. +Clicking in the scrollbar itself provides scrolling by windowsfull, +depending on which side of the slider is clicked. The slider itself +may be dragged for smooth scrolling. + + The position of the slider corresponds to the position of the window +in the buffer. In particular, the length of the slider is proportional +to the fraction of the buffer which appears in the window. + + The presence of the scrollbars is under control of the application or +may be customized by the user. By default a vertical scrollbar is +present in all windows (except the minibuffer), and there is no +horizontal scrollbar. + + +File: xemacs.info, Node: Toolbar Basics, Next: Gutter Basics, Prev: Scrollbar Basics, Up: GUI Components + +XEmacs Toolbars +=============== + + XEmacs has a default toolbar which provides shortcuts for some of the +commonly used operations (such as opening files) and applications (such +as the Info manual reader). Operations which require arguments will pop +up dialogs to get them. + + The position of the default toolbar can be customized. Also, several +toolbars may be present simultaneously (in different positions). VM, +for example, provides an application toolbar which shortcuts for +mail-specific operations like sending, saving, and deleting messages. + + +File: xemacs.info, Node: Gutter Basics, Next: Inhibiting, Prev: Toolbar Basics, Up: GUI Components + +XEmacs Gutters +============== + + Gutters are the most flexible of the GUI components described in this +section. In theory, the other GUI components could be implemented by +customizing a gutter, but in practice the other components were +introduced earlier and have their own special implementations. Gutters +tend to be more transient than the other components. Buffer tabs, for +example, change every time the selected buffer in the frame changes. +And for progress gauges a gutter to contain the gauge is typically +created on the fly when needed, then destroyed when the operation whose +staus is being displayed is completed. + + Buffer tabs, having somewhat complex behavior, deserve a closer look. +By default, a row of buffer tabs is displayed at the top of every frame. +(The tabs could be placed in the bottom gutter, but would be oriented +the same way and look rather odd. The horizontal orientation makes +putting them in a side gutter utterly impractical.) The buffer +displayed in the current window of a frame can be changed to a specific +buffer by clicking [mouse-1] on the corresponding tab in the gutter. + + Each tab contains the name of its buffer. The tab for the current +buffer in each frame is displayed in raised relief. The list of buffers +chosen for display in the buffer tab row is derived by filtering the +buffer list (like the `Buffers' menu). The list starts out with all +existing buffers, with more recently selected buffers coming earlier in +the list. + + Then "uninteresting" buffers, like internal XEmacs buffers, the +`*Message Log*' buffer, and so on are deleted from the list. Next, the +frame's selected buffer is determined. Buffers with a different major +mode from the selected buffer are removed from the list. Finally, if +the list is too long, the least recently used buffers are deleted from +the list. By default up to 6 most recently used buffers with the same +mode are displayed on tabs in the gutter. + + +File: xemacs.info, Node: Inhibiting, Next: Customizing, Prev: Gutter Basics, Up: GUI Components + +Inhibiting Display of GUI Components +==================================== + + Use of GUI facilities is a personal thing. Almost everyone agrees +that drawing via keyboard-based "turtle graphics" is acceptable to +hardly anyone if a mouse is available, but conversely emulating a +keyboard with a screenful of buttons is a painful experience. But +between those extremes the complete novice will require a fair amount +of time before toolbars and menus become dispensable, but many an +"Ancien Haquer" sees them as a complete waste of precious frame space +that could be filled with text. + + Display of all of the GUI components created by XEmacs can be +inhibited through the use of Customize. Customize can be accessed +through `Options | Customize' in the menu bar, or via `M-x customize'. +Then navigate through the Customize tree to `Emacs | Environment'. +Scrollbar and toolbar visibility is controlled via the `Display' group, +options `Scrollbars visible' and `Toolbar visible' respectively. +Gutter visibility is controlled by group `Gutter', option `Visible'. + + Or they can be controlled directly by `M-x customize-variable', by +changing the values of the variables `menubar-visible-p', +`scrollbars-visible-p', `toolbar-visible-p', or +`gutter-buffers-tab-visible-p' respectively. (The strange form of the +last variable is due to the fact that gutters are often used to display +transient widgets like progress gauges, which you probably don't want +to inhibit. It is more likely that you want to inhibit the default +display of the buffers tab widget, which is what that variable controls. +This interface is subject to change depending on developer experience +and user feedback.) + + Control of frame configuration can controlled automatically +according to various parameters such as buffer or frame because these +are "specifiers" *Note Specifiers: (lispref)Specifiers. Using these +features requires programming in Lisp; Customize is not yet that +sophisticated. Also, components that appear in various positions and +orientations can have display suppressed according to position. `C-h a +visible-p' gives a list of variables which can be customized. E.g., to +control the visibility of specifically the left-side toolbar only, +customize `left-toolbar-visible-p'. + + +File: xemacs.info, Node: Customizing, Prev: Inhibiting, Up: GUI Components + +Changing the Position, Orientation, and Appearance of GUI Components +==================================================================== + + #### Not documented yet. + + +File: xemacs.info, Node: XEmacs under X, Next: XEmacs under MS Windows, Prev: GUI Components, Up: Frame Using XEmacs Under the X Window System ====================================== @@ -191,6 +382,19 @@ applies: things, and the title is simply what appears above the window.)  +File: xemacs.info, Node: XEmacs under MS Windows, Prev: XEmacs under X, Up: Frame + +Using XEmacs Under Microsoft Windows +==================================== + + Use of XEmacs under MS Windows is not separately documented here, but +most operations available under the X Window System are also available +with MS Windows. + + Where possible, native MS Windows GUI components and capabilities are +used in XEmacs. + + File: xemacs.info, Node: Keystrokes, Next: Pull-down Menus, Prev: Frame, Up: Top Keystrokes, Key Sequences, and Key Bindings @@ -885,295 +1089,3 @@ When you select a menu item, Emacs executes the equivalent command.

Any Emacs command can be given a -"numeric argument" (also called a "prefix argument"). Some commands -interpret the argument as a repetition count. For example, giving an -argument of ten to the key `C-f' (the command `forward-char', move -forward one character) moves forward ten characters. With these -commands, no argument is equivalent to an argument of one. Negative -arguments are allowed. Often they tell a command to move or act in -the opposite direction. - - If your keyboard has a key (labelled with a diamond on -Sun-type keyboards and labelled `Alt' on some other keyboards), the -easiest way to specify a numeric argument is to type digits and/or a -minus sign while holding down the key. For example, - M-5 C-n - -would move down five lines. The characters `Meta-1', `Meta-2', and so -on, as well as `Meta--', do this because they are keys bound to -commands (`digit-argument' and `negative-argument') that are defined to -contribute to an argument for the next command. Digits and `-' -modified with Control, or Control and Meta, also specify numeric -arguments. - - Another way of specifying an argument is to use the `C-u' -(`universal-argument') command followed by the digits of the argument. -With `C-u', you can type the argument digits without holding down -modifier keys; `C-u' works on all terminals. To type a negative -argument, type a minus sign after `C-u'. Just a minus sign without -digits normally means -1. - - `C-u' followed by a character which is neither a digit nor a minus -sign has the special meaning of "multiply by four". It multiplies the -argument for the next command by four. `C-u' twice multiplies it by -sixteen. Thus, `C-u C-u C-f' moves forward sixteen characters. This -is a good way to move forward "fast", since it moves about 1/5 of a line -in the usual size frame. Other useful combinations are `C-u C-n', `C-u -C-u C-n' (move down a good fraction of a frame), `C-u C-u C-o' (make "a -lot" of blank lines), and `C-u C-k' (kill four lines). - - Some commands care only about whether there is an argument and not -about its value. For example, the command `M-q' (`fill-paragraph') with -no argument fills text; with an argument, it justifies the text as well. -(*Note Filling::, for more information on `M-q'.) Just `C-u' is a -handy way of providing an argument for such commands. - - Some commands use the value of the argument as a repeat count, but do -something peculiar when there is no argument. For example, the command -`C-k' (`kill-line') with argument N kills N lines, including their -terminating newlines. But `C-k' with no argument is special: it kills -the text up to the next newline, or, if point is right at the end of -the line, it kills the newline itself. Thus, two `C-k' commands with -no arguments can kill a non-blank line, just like `C-k' with an -argument of one. (*Note Killing::, for more information on `C-k'.) - - A few commands treat a plain `C-u' differently from an ordinary -argument.

Any Emacs command can be given a +"numeric argument" (also called a "prefix argument"). Some commands +interpret the argument as a repetition count. For example, giving an +argument of ten to the key `C-f' (the command `forward-char', move +forward one character) moves forward ten characters. With these +commands, no argument is equivalent to an argument of one. Negative +arguments are allowed. Often they tell a command to move or act in +the opposite direction. + + If your keyboard has a key (labelled with a diamond on +Sun-type keyboards and labelled `Alt' on some other keyboards), the +easiest way to specify a numeric argument is to type digits and/or a +minus sign while holding down the key. For example, + M-5 C-n + +would move down five lines. The characters `Meta-1', `Meta-2', and so +on, as well as `Meta--', do this because they are keys bound to +commands (`digit-argument' and `negative-argument') that are defined to +contribute to an argument for the next command. Digits and `-' +modified with Control, or Control and Meta, also specify numeric +arguments. + + Another way of specifying an argument is to use the `C-u' +(`universal-argument') command followed by the digits of the argument. +With `C-u', you can type the argument digits without holding down +modifier keys; `C-u' works on all terminals. To type a negative +argument, type a minus sign after `C-u'. Just a minus sign without +digits normally means -1. + + `C-u' followed by a character which is neither a digit nor a minus +sign has the special meaning of "multiply by four". It multiplies the +argument for the next command by four. `C-u' twice multiplies it by +sixteen. Thus, `C-u C-u C-f' moves forward sixteen characters. This +is a good way to move forward "fast", since it moves about 1/5 of a line +in the usual size frame. Other useful combinations are `C-u C-n', `C-u +C-u C-n' (move down a good fraction of a frame), `C-u C-u C-o' (make "a +lot" of blank lines), and `C-u C-k' (kill four lines). + + Some commands care only about whether there is an argument and not +about its value. For example, the command `M-q' (`fill-paragraph') with +no argument fills text; with an argument, it justifies the text as well. +(*Note Filling::, for more information on `M-q'.) Just `C-u' is a +handy way of providing an argument for such commands. + + Some commands use the value of the argument as a repeat count, but do +something peculiar when there is no argument. For example, the command +`C-k' (`kill-line') with argument N kills N lines, including their +terminating newlines. But `C-k' with no argument is special: it kills +the text up to the next newline, or, if point is right at the end of +the line, it kills the newline itself. Thus, two `C-k' commands with +no arguments can kill a non-blank line, just like `C-k' with an +argument of one. (*Note Killing::, for more information on `C-k'.) + + A few commands treat a plain `C-u' differently from an ordinary +argument. A few others may treat an argument of just a minus sign +differently from an argument of -1.

First go to the beginning of the text you want to -capitalize and type `C-' to put the mark there, then move to the -end, and then type `C-x C-u' to capitalize the selected region. You -can also set the mark at the end of the text, move to the beginning, -and then type `C-x C-u'. Most commands that operate on the text in the -region have the word `region' in their names. - - The most common way to set the mark is with the `C-' command -(`set-mark-command'). This command sets the mark where point is. You -can then move point away, leaving the mark behind. It is actually -incorrect to speak of the character `C-'; there is no such -character. When you type while holding down , you get the -character `C-@' on most terminals. This character is actually bound to -`set-mark-command'. But unless you are unlucky enough to have a -terminal where typing `C-' does not produce `C-@', you should -think of this character as `C-'. - - Since terminals have only one cursor, Emacs cannot show you where the -mark is located. Most people use the mark soon after they set it, before -they forget where it is. But you can see where the mark is with the -command `C-x C-x' (`exchange-point-and-mark') which puts the mark where -point was and point where the mark was. The extent of the region is -unchanged, but the cursor and point are now at the previous location of -the mark. - - Another way to set the mark is to push the mark to the beginning of a -buffer while leaving point at its original location. If you supply an -argument to `C-<' (`mark-beginning-of-buffer'), the mark is pushed N/10 -of the way from the true beginning of the buffer. You can also set the -mark at the end of a buffer with `C->' (`mark-end-of-buffer').

You can then indent, case-convert, or kill the whole -paragraph. In the same fashion, `C-M-h' (`mark-defun') puts point -before and the mark after the current or following defun (*note -Defuns::). `C-x C-p' (`mark-page') puts point before the current page -(or the next or previous, depending on the argument), and mark at the -end (*note Pages::). The mark goes after the terminating page -delimiter (to include it), while point goes after the preceding page -delimiter (to exclude it). Finally, `C-x h' (`mark-whole-buffer') sets -up the entire buffer as the region by putting point at the beginning -and the mark at the end. - diff --git a/lib-src/ChangeLog b/lib-src/ChangeLog index 5fa22ce..4536485 100644 --- a/lib-src/ChangeLog +++ b/lib-src/ChangeLog @@ -1,3 +1,7 @@ +2000-12-31 Martin Buchholz + + * XEmacs 21.2.39 is released. + 2000-12-05 Martin Buchholz * XEmacs 21.2.38 is released. diff --git a/lisp/ChangeLog b/lisp/ChangeLog index 379143a..9f3de07 100644 --- a/lisp/ChangeLog +++ b/lisp/ChangeLog @@ -1,3 +1,50 @@ +2000-12-31 Martin Buchholz + + * XEmacs 21.2.39 is released. + +2000-12-27 Martin Buchholz + + * byte-optimize.el (byte-optimize-cond): + (byte-optimize-cond-1): New. + Rewrite `cond' in terms of `if' and `or', which are easier to optimize. + Optimizes (cond (x nil)) ==> nil. + Provide better diagnostic on malformed expr like (cond foo). + +2000-12-20 Stephen J.
