+
+							*Haiku*
+This file contains the particularities for the Haiku version of Vim.  For
+matters not discussed in this file, Vim behaves very much like the Unix
+|os_unix.txt| version.
+
+Haiku is an open-source operating system inspired by BeOS, that specifically
+targets personal computing.

+ 3. The Haiku GUI		|haiku-gui|
+ 4. The $VIM directory		|haiku-vimdir|

+13. Bugs & things To Do		|haiku-bugs|
+
+
+1. General						*haiku-general*
+
+The default syntax highlighting mostly works with different foreground colors
+to highlight items.  This works best if you set your Terminal window to a
+darkish background and light letters.  Some middle-grey background (for
+instance (r,g,b)=(168,168,168)) with black letters also works nicely.
+
+
+2. Compiling Vim					*haiku-compiling*
+
+Vim can be compiled using the standard configure/make approach. Running
+./configure without any arguments or passing --enable-gui=haiku, will compile
+vim with the Haiku GUI support.  Run ./configure --help , to find out other
+features you can enable/disable.
+
+Now you should use "make" to compile Vim, then "make install" to install it.
+For seamless integration into the Haiku the GUI-less vim binary should be
+additionally installed over the GUI version. Typical build commands are: >
+
+  ./configure --prefix=`finddir B_SYSTEM_NONPACKAGED_DIRECTORY` \
+    --datarootdir=`finddir B_SYSTEM_NONPACKAGED_DATA_DIRECTORY` \
+    --mandir=`finddir B_SYSTEM_NONPACKAGED_DIRECTORY`/documentation/man \
+  make clean
+  make install
+
+  ./configure --prefix=`finddir B_SYSTEM_NONPACKAGED_DIRECTORY`  \
+    --datarootdir=`finddir B_SYSTEM_NONPACKAGED_DATA_DIRECTORY` \
+    --mandir=`finddir B_SYSTEM_NONPACKAGED_DIRECTORY`/documentation/man \
+    --disable-gui
+  make clean
+  make install
+
+
+3. The Haiku GUI					*haiku-gui*
+
+Normally Vim starts with the GUI if you start it as gvim or vim -g.  The vim
+version with GUI tries to determine if it was started from the Tracker instead
+of the Terminal, and if so, uses the GUI anyway. However, the current detection
+scheme is fooled if you use the command "vim - </dev/null".
+
+Stuff that does not work yet:
+
+- Mouse up events are not generated when outside the window. This may be a bug in
+  Haiku. You can notice this when selecting text and moving the cursor outside
+  the window, then letting go of the mouse button.  Another way is when you
+  drag the scrollbar and do the same thing.  Because Vim still thinks you are
+  still playing with the scrollbar it won't change it itself. I provided a
+  workaround which kicks in when the window is activated or deactivated (so it
+  works best with focus- follows-mouse turned on).
+- The cursor does not flash (very low priority; I'm not sure I even like it
+  when it flashes)
+
+
+4. The $VIM directory					*haiku-vimdir*
+
+$VIM is the symbolic name for the place where Vims support files are stored.
+The default value for $VIM is set at compile time and can be determined with >
+
+  :version
+
+The normal value is /boot/common/data/vim.  If you don't like it you can
+set the VIM environment variable to override this, or set 'helpfile' in your
+.vimrc: >
+
+  :if version >= 500
+  :    set helpfile=~/vim/runtime/doc/help.txt
+  :    syntax on
+  :endif
+
+
+5. The $USER_SETTINGS_DIR directory		*haiku-user-settings-dir*
+
+$USER_SETTINGS_DIR is the symbolic name for the place where Haiku
+configuration and settings files are stored.
+
+The normal value is /boot/home/config/settings.
+
+
+6. Drag & Drop						*haiku-dragndrop*
+
+You can drop files and directories on either the Vim icon (starts a new Vim
+session, unless you use the File Types application to set Vim to be "Single
+Launch") or on the Vim window (starts editing the files).  Dropping a folder
+sets Vim's current working directory. |:cd| |:pwd| If you drop files or
+folders with either SHIFT key pressed, Vim changes directory to the folder
+that contains the first item dropped.  When starting Vim, there is no need to
+press shift: Vim behaves as if you do.
+
+Files dropped set the current argument list. |argument-list|
+
+
+7. Single Launch vs. Multiple Launch			*haiku-launch*
+
+As distributed Vim's Application Flags (as seen in the FileTypes preference)
+are set to Multiple Launch.  If you prefer, you can set them to Single Launch
+instead.  Attempts to start a second copy of Vim will cause the first Vim to
+open the files instead.  This works from the Tracker but also from the command
+line.  In the latter case, non-file (option) arguments are not supported.
+Another drawback of the Single Launch is silent ignore of "Open With ..."
+requests by vim instance that running as non-GUI application even GUI support
+was compiled in. Vim instance running with GUI has no such problems.
+
+NB: Only the GUI version has a BApplication (and hence Application Flags).
+This section does not apply to the GUI-less version, should you compile one.
+
+
+8. Fonts						*haiku-fonts*
+
+Set fonts with >
+
+  :set guifont=DejaVu_Sans_Mono/Book/12
+
+where the first part is the font family, the second part the style, and the
+third part the size.  You can use underscores instead of spaces in family and
+style.
+
+Best results are obtained with monospaced fonts.  Vim attempts to use all
+fonts in B_FIXED_SPACING mode but apparently this does not work for
+proportional fonts (despite what the BeBook says).
+
+To verify which encodings are supported by the current font give the >
+
+  :digraphs
+
+command, which lists a bunch of characters with their ISO Latin 1 encoding.
+If, for instance, there are "box" characters among them, or the last character
+isn't a dotted-y, then for this font the encoding does not work.
+
+If the font you specify is unavailable, you get the system fixed font.
+
+GUI Font Selection Dialog is available at giving the >
+
+  :set guifont=*
+
+command.
+
+
+9. The meta key modifier				*haiku-meta*
+
+The META key modifier is obtained by the left or right OPTION keys.  This is
+because the ALT (aka COMMAND) keys are not passed to applications.
+
+
+10. Mouse key mappings					*haiku-mouse*
+
+Vim calls the various mouse buttons LeftMouse, MiddleMouse and RightMouse.  If
+you use the default Mouse preference settings these names indeed correspond to
+reality.  Vim uses this mapping:
+
+    Button 1 -> LeftMouse,
+    Button 2 -> RightMouse,
+    Button 3 -> MiddleMouse.
+
+If your mouse has fewer than 3 buttons you can provide your own mapping from
+mouse clicks with modifier(s) to other mouse buttons.  See the file
+$VIM/macros/swapmous.vim for an example.		|gui-mouse-mapping|
+
+
+11. Color names						*haiku-colors*
+
+Vim has a number of color names built-in.  Additional names are read from the
+file $VIMRUNTIME/rgb.txt, if present.  This file is basically the color
+database from X.  Names used from this file are cached for efficiency.
+
+
+12. GUI Toolbar Images					*haiku-toolbar-images*
+
+Alternative set of toolbar images should be the PNG image of any height you
+like. Image width is calculated to contain at least 32 buttons in one-row
+cells.
+The image should be stored under the name $VIRUNTIME/bitmaps/builtin-tools.png
+More info about the buttons assignment are at |builtin-tools|.
+
+
+13. Credits						*haiku-support-credits*
+
+Haiku port is based on work done for BeOS version by many people
+ - BeBox GUI support Copyright 1998 by Olaf Seibert;
+ - Ported to R4 by Richard Offer <richard@whitequeen.com> Jul 99;
+ - Those who contributed, not listed above but not forgotten;
+ - Haiku support by Siarzhuk Zharski <imker@gmx.li> Apr-Mai 2009.
+
+All the changes and patches released under vim-license.
+
+Thank you, all!
+
+
+13. Bugs & things To Do					*haiku-bugs*
+
+The port is under development now and far away from the perfect state. Bug
+reports, patches and wishes are welcome.
