X<menuBar>

=head1 menuBar

B<< The exact syntax used is I<almost> solidified. >>
In the menus, B<DON'T> try to use menuBar commands that add or remove a
menuBar.

Note that in all of the commands, the B<< I</path/> >> I<cannot> be
omitted: use B<./> to specify a menu relative to the current menu.

=head2 Overview of menuBar operation

For the menuBar XTerm escape sequence C<ESC ] 703 ; Pt ST>, the syntax
of C<Pt> can be used for a variety of tasks:

At the top level is the current menuBar which is a member of a circular
linked-list of other such menuBars.

The menuBar acts as a parent for the various drop-down menus, which in
turn, may have labels, separator lines, menuItems and subMenus.

The menuItems are the useful bits: you can use them to mimic keyboard
input or even to send text or escape sequences back to rxvt.

The menuBar syntax is intended to provide a simple yet robust method of
constructing and manipulating menus and navigating through the
menuBars.

The first step is to use the tag B<< [menu:I<name>] >> which creates
the menuBar called I<name> and allows access. You may now or menus,
subMenus, and menuItems. Finally, use the tag B<[done]> to set the
menuBar access as B<readonly> to prevent accidental corruption of the
menus. To re-access the current menuBar for alterations, use the tag
B<[menu]>, make the alterations and then use B<[done]>

X<menuBarCommands>

=head2 Commands

=over 4

=item B<< [menu:+I<name>] >>

access the named menuBar for creation or alteration. If a new menuBar
is created, it is called I<name> (max of 15 chars) and the current
menuBar is pushed onto the stack

=item B<[menu]>

access the current menuBar for alteration

=item B<< [title:+I<string>] >>

set the current menuBar's title to I<string>, which may contain the
following format specifiers:
B<%%> : literal B<%> character
B<%n> : rxvt name (as per the B<-name> command-line option)
B<%v> : rxvt version

=item B<[done]>

set menuBar access as B<readonly>.
End-of-file tag for B<< [read:+I<file>] >> operations.

=item B<< [read:+I<file>] >>

read menu commands directly from I<file> (extension ".menu" will be
appended if required.) Start reading at a line with B<[menu]> or B<<
[menu:+I<name> >> and continuing until B<[done]> is encountered.

Blank and comment lines (starting with B<#>) are ignored. Actually,
since any invalid menu commands are also ignored, almost anything could
be construed as a comment line, but this may be tightened up in the
future ... so don't count on it!.

=item B<< [read:+I<file>;+I<name>] >>

The same as B<< [read:+I<file>] >>, but start reading at a line with
B<< [menu:+I<name>] >> and continuing until B<< [done:+I<name>] >> or
B<[done]> is encountered.

=item B<[dump]>

dump all menuBars to the file B</tmp/rxvt-PID> in a format suitable for
later rereading.

=item B<[rm:name]>

remove the named menuBar

=item B<[rm] [rm:]>

remove the current menuBar

=item B<[rm*] [rm:*]>

remove all menuBars

=item B<[swap]>

swap the top two menuBars

=item B<[prev]>

access the previous menuBar

=item B<[next]>

access the next menuBar

=item B<[show]>

Enable display of the menuBar

=item B<[hide]>

Disable display of the menuBar

=item B<< [pixmap:+I<name>] >>

=item B<< [pixmap:+I<name>;I<scaling>] >>

(set the background pixmap globally

B<< A Future implementation I<may> make this local to the menubar >>)

=item B<< [:+I<command>:] >>

ignore the menu readonly status and issue a I<command> to or a menu or
menuitem or change the ; a useful shortcut for setting the quick arrows
from a menuBar.

=back

X<menuBarAdd>

=head2 Adding and accessing menus

The following commands may also be B<+> prefixed.

=over 4

=item B</+>

access menuBar top level

=item B<./+>

access current menu level

=item B<../+>

access parent menu (1 level up)

=item B<../../>

access parent menu (multiple levels up)

=item B<< I</path/>menu >>

add/access menu

=item B<< I</path/>menu/* >>

add/access menu and clear it if it exists

=item B<< I</path/>{-} >>

add separator

=item B<< I</path/>{item} >>

add B<item> as a label

=item B<< I</path/>{item} action >>

add/alter I<menuitem> with an associated I<action>

=item B<< I</path/>{item}{right-text} >>

add/alter I<menuitem> with B<right-text> as the right-justified text
and as the associated I<action>

=item B<< I</path/>{item}{rtext} action >>

add/alter I<menuitem> with an associated I<action> and with B<rtext> as
the right-justified text.

=back

=over 4

=item Special characters in I<action> must be backslash-escaped:

B<\a \b \E \e \n \r \t \octal>

=item or in control-character notation:

B<^@, ^A .. ^Z .. ^_, ^?>

=back

To send a string starting with a B<NUL> (B<^@>) character to the
program, start I<action> with a pair of B<NUL> characters (B<^@^@>),
the first of which will be stripped off and the balance directed to the
program. Otherwise if I<action> begins with B<NUL> followed by
non-+B<NUL> characters, the leading B<NUL> is stripped off and the
balance is sent back to rxvt.

As a convenience for the many Emacs-type editors, I<action> may start
with B<M-> (eg, B<M-$> is equivalent to B<\E$>) and a B<CR> will be
appended if missed from B<M-x> commands.

As a convenience for issuing XTerm B<ESC]> sequences from a menubar (or
quick arrow), a B<BEL> (B<^G>) will be appended if needed.

=over 4

=item For example,

B<M-xapropos> is equivalent to B<\Exapropos\r>

=item and

B<\E]703;mona;100> is equivalent to B<\E]703;mona;100\a>

=back

The option B<< {I<right-rtext>} >> will be right-justified. In the
absence of a specified action, this text will be used as the I<action>
as well.

=over 4

=item For example,

B</File/{Open}{^X^F}> is equivalent to B</File/{Open}{^X^F} ^X^F>

=back

The left label I<is> necessary, since it's used for matching, but
implicitly hiding the left label (by using same name for both left and
right labels), or explicitly hiding the left label (by preceeding it
with a dot), makes it possible to have right-justified text only.

=over 4

=item For example,

B</File/{Open}{Open} Open-File-Action>

=item or hiding it

B</File/{.anylabel}{Open} Open-File-Action>

=back

X<menuBarRemove>

=head2 Removing menus

=over 4

=item B<< -/*+ >>

remove all menus from the menuBar, the same as B<[clear]>

=item B<< -+I</path>menu+ >>

remove menu

=item B<< -+I</path>{item}+ >>

remove item

=item B<< -+I</path>{-} >>

remove separator)

=item B<-/path/menu/*>

remove all items, separators and submenus from menu

=back

X<menuBarArrows>

=head2 Quick Arrows

The menus also provide a hook for I<quick arrows> to provide easier
user access. If nothing has been explicitly set, the default is to
emulate the curror keys. The syntax permits each arrow to be altered
individually or all four at once without re-entering their common
beginning/end text. For example, to explicitly associate cursor actions
with the arrows, any of the following forms could be used:

=over 4

=item B<< <r>+I<Right> >>

=item B<< <l>+I<Left> >>

=item B<< <u>+I<Up> >>

=item B<< <d>+I<Down> >>

Define actions for the respective arrow buttons

=item B<< <b>+I<Begin> >>

=item B<< <e>+I<End> >>

Define common beginning/end parts for I<quick arrows> which used in
conjunction with the above <r> <l> <u> <d> constructs

=back

=over 4

=item For example, define arrows individually,

 <u>\E[A

 <d>\E[B

 <r>\E[C

 <l>\E[D

=item or all at once

 <u>\E[AZ<><d>\E[BZ<><r>\E[CZ<><l>\E[D

=item or more compactly (factoring out common parts)

 <b>\E[<u>AZ<><d>BZ<><r>CZ<><l>D

=head1 CONFIGURE OPTIONS

General hint: if you get compile errors, then likely your configuration
hasn't been tested well. Either try with --enable-everything or use the
./reconf script as a base for experiments. ./reconf is used by myself,
so it should generally be a working config. Of course, you should always
report when a combination doesn't work, so it can be fixed. Marc Lehmann
<rxvt@schmorp.de>.

=over 4

=item --enable-everything

Add support for all non-multichoice options listed in "./configure
--help". Note that unlike other enable options this is order dependant.
You can specify this and then disable options which this enables by
I<following> this with the appropriate commands.

=item --enable-xft

Add support for Xft (anti-aliases, among others) fonts. Xft fonts are
slower and require lots of memory, but as long as you don't use them, you
don't pay for them.

=item --enable-font-styles

Add support for B<bold>, I<italic> and B<< I<bold italic> >> font
styles. The fonts can be set manually or automatically.

=item --with-codesets=NAME,...

Compile in support for additional codeset (encoding) groups (eu, vn are
always compiled in, which includes most 8-bit character sets). These
codeset tables are currently only used for driving X11 core fonts, they
are not required for Xft fonts. Compiling them in will make your binary
bigger (together about 700kB), but it doesn't increase memory usage unless
you use an X11 font requiring one of these encodings.

=begin table

        all     all available codeset groups
        cn      common chinese encodings
        cn_ext  rarely used but very big chinese encodigs
        jp      common japanese encodings
        jp_ext  rarely used but big japanese encodings
        kr      korean encodings

=end table

=item --enable-xim

Add support for XIM (X Input Method) protocol. This allows using
alternative input methods (e.g. kinput2) and will also correctly
set up the input for people using dead keys or compose keys.

=item --enable-unicode3

Enable direct support for displaying unicode codepoints above
65535 (the basic multilingual page). This increases storage
requirements per character from 2 to 4 bytes. X11 fonts do not yet
support these extra characters, but Xft does.

Please note that rxvt-unicode can store unicode code points >65535
even without this flag, but the number of such characters is
limited to a view thousand (shared with combining characters,
see next switch), and right now rxvt-unicode cannot display them
(input/output and cut&paste still work, though).

=item --enable-combining

Enable automatic composition of combining characters into
composite characters. This is required for proper viewing of text
where accents are encoded as seperate unicode characters. This is
done by using precomposited characters when available or creating
new pseudo-characters when no precomposed form exists.

Without --enable-unicode3, the number of additional precomposed
characters is rather limited (2048, if this is full, rxvt will use the
private use area, extending the number of combinations to 8448). With
--enable-unicode3, no practical limit exists. This will also enable
storage of characters >65535.

The combining table also contains entries for arabic presentation forms,
but these are not currently used. Bug me if you want these to be used.

=item --enable-fallback(=CLASS)

When reading resource settings, also read settings for class CLASS
(default: Rxvt). To disable resource fallback use --disable-fallback.

=item --with-res-name=NAME

Use the given name (default: urxvt) as default application name when
reading resources. Specify --with-res-name=rxvt to replace rxvt.

=item --with-res-class=CLASS

Use the given class (default: URxvt) as default application class
when reading resources.  Specify --with-res-class=Rxvt to replace
rxvt.

=item --enable-utmp

Write user and tty to utmp file (used by programs like F<w>) at
start of rxvt execution and delete information when rxvt exits.

=item --enable-wtmp

Write user and tty to wtmp file (used by programs like F<last>) at
start of rxvt execution and write logout when rxvt exits.  This
option requires --enable-utmp to also be specified.

=item --enable-lastlog

Add support for XPM background pixmaps.

=item --enable-transparency

Add support for inheriting parent backgrounds thus giving a fake
transparency to the term.

=item --enable-fading

Add support for fading the text when focus is lost.

=item --enable-tinting

Add support for tinting of transparent backgrounds.

Add support for the original rxvt scrollbar.

=item --enable-next-scroll

Add support for a NeXT-like scrollbar.

=item --enable-xterm-scroll

is the favourite of the rxvt-unicode author, having used it for
many years.

=item --enable-half-shadow

Make shadows on the scrollbar only half the normal width & height.

=item --enable-ttygid

Change tty device setting to group "tty" - only use this if

Disable any handling of the delete key by us - let the X server
do it.

=item --disable-resources

Remove all resources checking.

=item --enable-xgetdefault

Make resources checking via XGetDefault() instead of our small
version which only checks ~/.Xdefaults, or if that doesn't exist
then ~/.Xresources.

=item --enable-strings

Add support for our possibly faster memset() function and other
various routines, overriding your system's versions which may
have been hand-crafted in assembly or may require extra libraries
to link in. (this breaks ANSI-C rules and has problems on many
GNU/Linux systems).

=item --disable-swapscreen

Remove support for swap screen.

=item --enable-frills

Add support for many small features that are not essential but nice to
have. Normally you want this, but for very small binaries you may want to
disable this.

=item --enable-iso14755

Enable extended ISO 14755 support (see @@RXVT_NAME@@(1), or
F<doc/rxvt.1.txt>). Basic support (section 5.1) is enabled by

this switch.

accelerator) while the control key is held down.  This option
requires --enable-mousewheel to also be specified.

=item --disable-new-selection

Remove support for mouse selection style like that of xterm.

=item --enable-dmalloc

Use Gray Watson's malloc - which is good for debugging See
http://www.letters.com/dmalloc/ for details If you use either this or the
next option, you may need to edit src/Makefile after compiling to point
DINCLUDE and DLIB to the right places.

You can only use either this option and the following (should
you use either) .

=item --enable-dlmalloc

Use Doug Lea's malloc - which is good for a production version
See L<http://g.oswego.edu/dl/html/malloc.html> for details.

=item --enable-smart-resize

Add smart growth/shrink behaviour when changing font size via from hot
keys. This should keep in a fixed position the rxvt corner which is
closest to a corner of the screen.

=item --enable-cursor-blink

Add support for a blinking cursor.

=item --enable-pointer-blank

Add support to have the pointer disappear when typing or inactive.

=item --with-name=NAME

Set the basename for the installed binaries (default: urxvt, resulting in
urxvt, urxvtd etc.). Specify --with-name=rxvt to replace rxvt.

=item --with-term=NAME

Change the environmental variable for the terminal to NAME (default
"rxvt")

=item --with-terminfo=PATH

Change the environmental variable for the path to the terminfo tree to
PATH.

=item --with-x

Use the X Window System (pretty much default, eh?).

=item --with-xpm-includes=DIR

Look for the XPM includes in DIR.

=item --with-xpm-library=DIR

Look for the XPM library in DIR.

=item --with-xpm

Not needed - define via --enable-xpm-background.
