A rewrite of the rxvt terminal emulator in javascript

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 default configuration (i.e. no "--enable-xxx" or "--disable-xxx" switches). Of course, you should always report when a combination doesn't work, so it can be fixed. Marc Lehmann [email protected].

All

--enable-everything
    Add (or remove) support for all non-multichoice options listed in
    "./configure --help".

    You can specify this and then disable options you do not like by
    *following* this with the appropriate "--disable-..." arguments, or
    you can start with a minimal configuration by specifying
    "--disable-everything" and than adding just the "--enable-..."
    arguments you want.

--enable-xft (default: enabled)
    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.

--enable-font-styles (default: on)
    Add support for bold, *italic* and *bold italic* font styles. The
    fonts can be set manually or automatically.

--with-codesets=NAME,... (default: all)
    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 used for driving X11 core fonts,
    they are not required for Xft fonts, although having them compiled
    in lets rxvt-unicode choose replacement fonts more intelligently.
    Compiling them in will make your binary bigger (all of together cost
    about 700kB), but it doesn't increase memory usage unless you use a
    font requiring one of these encodings.

all all available codeset groups zh common chinese encodings zh_ext rarely used but very big chinese encodings jp common japanese encodings jp_ext rarely used but big japanese encodings kr korean encodings --enable-xim (default: on) 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.

--enable-unicode3 (default: off)
    Recommended to stay off unless you really need non-BMP characters.

    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 few thousand (shared with combining characters, see next
    switch), and right now rxvt-unicode cannot display them
    (input/output and cut&paste still work, though).

--enable-combining (default: on)
    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 somewhat limited (the 6400 private use characters will
    be (ab-)used). With --enable-unicode3, no practical limit exists.

    This option will also enable storage (but not display) of characters
    beyond plane 0 (>65535) when --enable-unicode3 was not specified.

    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 (and tell me how these are to be used...).

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

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

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

--enable-utmp (default: on)
    Write user and tty to utmp file (used by programs like w) at start
    of rxvt execution and delete information when rxvt exits.

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

--enable-lastlog (default: on)
    Write user and tty to lastlog file (used by programs like lastlogin)
    at start of rxvt execution. This option requires --enable-utmp to
    also be specified.

--enable-afterimage (default: on)
    Add support for libAfterImage to be used for transparency and
    background images. It adds support for many file formats including
    JPG, PNG, SVG, TIFF, GIF, XPM, BMP, ICO, XCF, TGA and AfterStep
    image XML
    (<http://www.afterstep.org/visualdoc.php?show=asimagexml>).

    This option also adds such eye candy as blending an image over the
    root background, as well as dynamic scaling and bluring of
    background images.

    Note that with this option enabled, rxvt's memory footprint might
    increase by a few megabytes even if no extra features are used
    (mostly due to third-party libraries used by libAI). Memory
    footprint may somewhat be lowered if libAfterImage is configured
    without support for SVG.

--enable-transparency (default: on)
    Add support for backgrounds, creating illusion of transparency in
    the term.

--enable-fading (default: on)
    Add support for fading the text when focus is lost.

--enable-rxvt-scroll (default: on)
    Add support for the original rxvt scrollbar.

--enable-next-scroll (default: on)
    Add support for a NeXT-like scrollbar.

--enable-xterm-scroll (default: on)
    Add support for an Xterm-like scrollbar.

--disable-backspace-key
    Removes any handling of the backspace key by us - let the X server
    do it.

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

--disable-resources
    Removes any support for resource checking.

--disable-swapscreen
    Remove support for secondary/swap screen.

--enable-frills (default: on)
    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.

    A non-exhaustive list of features enabled by "--enable-frills"
    (possibly in combination with other switches) is:

      MWM-hints
      EWMH-hints (pid, utf8 names) and protocols (ping)
      urgency hint
      seperate underline colour (-underlineColor)
      settable border widths and borderless switch (-w, -b, -bl)
      visual depth selection (-depth)
      settable extra linespacing /-lsp)
      iso-14755 5.1 (basic) support
      tripleclickwords (-tcw)
      settable insecure mode (-insecure)
      keysym remapping support
      cursor blinking and underline cursor (-cb, -uc)
      XEmbed support (-embed)
      user-pty (-pty-fd)
      hold on exit (-hold)
      compile in built-in block graphics
      skip builtin block graphics (-sbg)
      separate highlightcolor support (-hc)

    It also enables some non-essential features otherwise disabled, such
    as:

      some round-trip time optimisations
      nearest color allocation on pseudocolor screens
      UTF8_STRING support for selection
      sgr modes 90..97 and 100..107
      backindex and forwardindex escape sequences
      view change/zero scrollback escape sequences
      locale switching escape sequence
      window op and some xterm/OSC escape sequences
      rectangular selections
      trailing space removal for selections
      verbose X error handling

--enable-iso14755 (default: on)
    Enable extended ISO 14755 support (see rxvt(1)). Basic support
    (section 5.1) is enabled by "--enable-frills", while support for
    5.2, 5.3 and 5.4 is enabled with this switch.

--enable-keepscrolling (default: on)
    Add support for continual scrolling of the display when you hold the
    mouse button down on a scrollbar arrow.

--enable-selectionscrolling (default: on)
    Add support for scrolling when the selection moves to the top or
    bottom of the screen.

--enable-mousewheel (default: on)
    Add support for scrolling via mouse wheel or buttons 4 & 5.

--enable-slipwheeling (default: on)
    Add support for continual scrolling (using the mouse wheel as an
    accelerator) while the control key is held down. This option
    requires --enable-mousewheel to also be specified.

--enable-smart-resize (default: off)
    Add smart growth/shrink behaviour when resizing. This should keep
    the window corner which is closest to a corner of the screen in a
    fixed position.

--enable-text-blink (default: on)
    Add support for blinking text.

--enable-pointer-blank (default: on)
    Add support to have the pointer disappear when typing or inactive.

--enable-perl (default: on)
    Enable an embedded perl interpreter. See the rxvtperl(3) manpage for
    more info on this feature, or the files in src/perl/ for the
    extensions that are installed by default. The perl interpreter that
    is used can be specified via the "PERL" environment variable when
    running configure. Even when compiled in, perl will *not* be
    initialised when all extensions have been disabled "-pe ""
    --perl-ext-common """, so it should be safe to enable from a
    resource standpoint.

--with-afterimage-config=DIR
    Look for the libAfterImage config script in DIR.

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

--with-term=NAME (default: rxvt-unicode)
    Change the environmental variable for the terminal to NAME.

--with-terminfo=PATH
    Change the environmental variable for the path to the terminfo tree
    to PATH.

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