This Document describes how to configure Yudit. 
=====================================================================
1 Configuration File Loading

 At start-up Yudit reads the configuration file:
  <prefix>/share/yudit/config/yudit-properties
 where <prefix> is the installation prefix, usually /usr.
 This is the system configuration file. If the file is found, it merges 
 the entries with the default compiled in the binary. After start-up 
 it tries  to create 
   ~/.yudit
   ~/.yudit/fonts
   ~/.yudit/data
 directories, if they are not there. ~/ means the user's home 
 directory, like '/home/gsinai'. It tries to load 
   ~/.yudit/yudit.properties
 file. The existing entries in this file will override the previously
 loaded  system configuration entries.

 When exiting Yudit, yudit will merge certain parameters in this file
 with some parameters that the user can change inside Yudit. Currently
 the overwritten parameters are:
  yudit.editor.font
  yudit.editor.fontsize
  yudit.editor.input
  yudit.filetypes

=====================================================================
2 Configuration File Format

 The configuration files consists of lines of:
  hierarchical.key.string=value
 or
  hierarchical.key.string=value1,value2,value3
 It is very important that no extra space is left anywhere.
 It is possible to use the '\<newline>' character to join two
 separate lines  but it is not desirable, especially in the user 
 config file. Yudit will join these lines in that file.
 
 Keep in mind: when an array is specified in the system config file 
 with value1,value2,value3 and the same array is in the user config
 file, with myvalue1,myvalue2 all elements of the array will be coming
 from the user config file: myvalue1,myvalue2.

=====================================================================
3 Basic Configuration Parameters

These are the parameters that have profound effect on yudit. You can
add virtual fonts, choices to the editor window like font sizes, 
input methods.

---------------------------------------------------------------------
3.1 yudit.datapath

 Array parameter. Example: 
  yudit.datapath=/usr/share/yudit/data,/home/gsinai/data,...
 This is a very important parameter. This will define the search path,
 yudit will locate the my-files it needs to map fonts, create input
 methods and converters.
 Note that 
  <prefix>/yudit/data
  ~/.yudit/data
 directories will always be appended to the list.

---------------------------------------------------------------------
3.2 yudit.fontpath

 Array parameter. Example:
  yudit.fontpath=/usr/share/yudit/fonts,/usr/share/truetype/,...
 This parameter defines the search path for True Types fonts.
 Note that 
  <prefix>/yudit/fonts
  ~/.yudit/fonts
 directories will always be appended to the list.

---------------------------------------------------------------------
3.3 yudit.fonts, yudit.editor.fonts (4.1)

 Array parameters. Both define the available fonts. 
 yudit.editor.fonts(4.1) defines the available fonts that can be selected
 from Yudit in the editor window. The available fonts in other parts of 
 the gui (labels, buttons) are a superset of the two.

 Example:
  yudit.editor.fonts=default,TrueType,Bitmap
  yudit.fonts=buttonfont,labelfont
 With this the following virtual fonts will be available:

 Shift-F1 - default
 Shift-F2 - TrueType
 Shift-F3 - Bitmap

 Any names can be used. The name "None" or "none" are specials they
 mean that no font change is desirable even though the corresponding
 Shift-Fxx combination was pressed.

 These virtual font names should be defined later in
  yudit.font.<fontname>
 parameter. The name default is defined internally, and it is not
 desirable to be defined in yudit.font.default unless you know what
 you are doing.
---------------------------------------------------------------------
3.4 yudit.font.<fontname>

 Array. This defines the virtual font that was specified in 3.3.
 Example:
  yudit.font.TrueType=arial.ttf,cyberbit.ttf,*-iso8859-1
 This defines a virtual font that can be referred to by the TrueType
 alias. This virtual font tries to find, 3 font files in the 
 fontpath (3.2) and if not found it tries to load them as x11 fonts.
 Most likely it will find:
  /usr/share/yudit/font/arial.ttf
  /usr/share/yudit/font/cyberbit.ttf
 and it wont find any file name  *-iso8859-1, so it will try to get 
 the closes match from X11 server, some font like:
    -adobe-courier-bold-o-normal--12-120-75-75-m-70-iso8859-1
 in case the font size we use was 12. The *-iso8859-1 was a bit
 lazy declaration, it can be defined to be more accurate.

 Yudit has built-in converters for most of the standard X11 
 font encodings.(source swindow/sx11/SX11Font.cpp)
  *-iso10646-1 
  *-iso8859-<1-9>
  *-koi8-1
  *-koi8-r
  *-ksc5601*
  *-jisx0208*
  *-jisx0201*
  *-jisx0212*-0
  *-big5*
  *-gb2312*
  *-iso646*
 To check the fonts available in your X11 server types 
  xlsfonts
 at the shell prompt.

 Yudit has has built-in ucs-2 converter for True Type fonts. 
 This is good for True Type fonts that have platform=3 encoding=1
 platform=2 encoding=1 or platform=1 attributes. If you have a font
 that does not have unicode table I need to modify the encodingVector
 in swindow/SFontTTF.cpp in the yudit source tree to add an encoder.
 Please send me your modifications if any.

=====================================================================
4 Menu Configuration Parameters

These configuration parameters will make up choices in the editor.

---------------------------------------------------------------------
4.1 yudit.editor.fonts

 Array. It defines the font choices in the gui. See also
 
  yudit.fonts

---------------------------------------------------------------------
4.2 yudit.editor.fontsizes

 Array. It defines the available font sizes.
 Example:
  yudit.editor.fontsize=12,14,16,18,24,48

 As X11 font sizes will be defined as integers, please do not use
 floating point values here. This value will replace the font size
 in XLFD for X11 fonts. True Type fonts will be scaled as if the screen
 were 72dpi.  

---------------------------------------------------------------------
4.3 yudit.editor.inputs

 Array. It defines the user-selectable input methods. These input methods
 can come from a .my file  on yudit.datapath (3.1.). Please note the the
 kmap files in <prefix>/yudit/src are installed for reference only. 
 They can only be used after being converted into .my format and properly 
 put in a directory on yudit.datapath - most of them are.

 config example:
  yudit.editor.inputs=straight,unicode,kinput2,Hungarian,None,Esperanto\
     freehand
  
 This will load:
 F1 straight: built-in - no mapping
 F2 unicode: build-in - \uxxxx escapes
 F3 kinput2: built-in - _JAPANESE_CONVERSION
 F4 Hungarian: external Hungarian.my file is searched and
  possibly found in /usr/share/yudit/data/Hungarian.my
 F5 None: nothing will happen when pressing F5
 F6 Esperanto: external, like Hungarian
 F7 freehand: internal, handwriting engine with external handwriting 
  description files.

 If you want to create you own .my keyboard input file, you should 
 read the <prefix>/share/yudit/doc/keymap-format.txt
 file, and consult the man page for the mytool program.

 As kmaps can be used as external text converters, uniconv -h will
 list the ones it can find on the datapath.

 You can also create your own freehand recognitin file. Please read
 <prefix>/share/yudit/doc/README-FREEHAND for a recepie. 

---------------------------------------------------------------------
4.4 yudit.editor.filetypes

 Array. This list will be appended to the original list of file types in
 the File Dialog. Normally File Dialog would show the built-in types 
 only. This is also known as encoding (3.6.)
 Exapmle:
  yudit.editor.filetypes=Hungarian,Hangul
 I use these key maps to transliterate Hungarian or Hangul text.

=====================================================================
5. Default Configuration Parameters

These parameters set some initial values.

---------------------------------------------------------------------
5.1 yudit.default.filtype

 String. It defines the encoding used initially when invoking Yudit.
 To get a full list of supported encodings type 
  uniconv -h
 in a shell window. This is also known as File Type in the file dialog
 window.
 Example:
 yudit.default.filetype=utf-8

---------------------------------------------------------------------
5.2 yudit.default.printer.options

 String. It defines the options that is passed to the 'lpr' command
 when printing.
 Example:
  yudit.default.printer.options=-P PrinterName

---------------------------------------------------------------------
5.3 yudit.default.preview.command

 String. It defines the command used when the preview button is 
 pressed. This is a full unix command that will be executed by
  /bin/sh -c 'whatever you configured'
 and the postscript output will be piped into this command.
 Example:
  yudit.default.preview.command=ghostview -

---------------------------------------------------------------------
5.4 yudit.default.clipboard.encoding

 This is the clipboard encoder to cut and paste in X11 if the requested
 text type is COMPOUND_TEXT. COMPOUND_TEXT could be decoded with yudit
 if there were an universal decoder. Encoding on the other hand, has
 some ambiguity as there are characters that occupy the same unicode
 character but they are distinct in COMPOUND_TEXT. For this, reason,
 and because yudit does not have a universal decoder, we need to 
 explicitly set this encoder. Try to use some iso-2022-x11 for Japanese
 XWindow or ksc-5601-x11 for Korean XWindow.

5.5 yudit.default.geometry

 This specifies the initial size of the editor window. The default
 value is "780x480". That is 780 pixels wide 480 pixels high.

=====================================================================
6 Configuration Parameters to Change Appearance

These parameters change the colors, fonts in the gui and the editing
area. All these parameters are strings. All colors can be color names
or #rrggbb values where rr,gg and bb are 8-bit hexadecimal color codes
for red, green and blue color components. Boolean values can be true or
false.

---------------------------------------------------------------------
6.1 yudit.default.language

 The language of the user interface. Please take a look at
  <prefix>/share/yudit/locale/
 to see the two letter names the are supported.
 Example:
 yudit.default.language=ja
 If this parameter is not present or it is a zero sized string the
 environment variable LANG or if not present LANGUAGE is used. 
 If everything fails English is used.
 If you are interested in translating yudit to your own language
 you should read  <prefix>/share/yudit/README.TXT
