NAME
yudit - Unicode Editor for The X Window System
SYNOPSIS
yudit [ -e encoding ] [[ file-name [ file-name... ]]
DESCRIPTION
yudit is a Unicode text editor.
When a user runs yudit for the first time $HOME/.yudit, $HOME/.yudit/data,
$HOME/.yudit/fonts, and $HOME/.yudit/syntax are created.
The configuration file can be edited inside yudit. For the detailed description of usage
and configuration take a look at the on-line manual.
If you are planning to save files with yudit please note that the format preferred
encoding format for Unicode files is utf-8.
Yudit can convert between different encoding methods, but if you do not need a GUI
consider uniconv.
OPTIONS
-e encoding
Encoding determines how yudit interacts with character streams: file input, file
output, cut and paste. XInput encoding is set up to use an independent, fixed
encoder.
If you received yudit through the yudit distribution, the following encoding
methods are inclusively supported:
utf-8, utf-7, utf-16, utf-16-le, utf-16-be, euc-jp, iso-2022-jp, shift-jis, big-5,
gb-2312 and java.
For a detailed description of these refer to uniconv man page.
Yudit can also use the keyboard input files as a transliterating text converters.
file-name
is the file yudit should read into its editor buffer at start-up. When multiple
files are specified, they become available in the history of the command area. The
history can be viewed there by pressing the up and down arrow keys.
COMMANDS
Yudit has an editor area and a command area.
Some of the commands need the documentation files to be available uncompressed. They may
come in a separate yudit-doc package.
Some of the commands require confirmation to execute. One example is when we want to
replace an unsaved editor buffer with a new file. If the editor buffer was not saved, the
command will abort unless -yes option is given.
help Load a help file, which is a FAQ.TXT document in your language. For language
settings refer to yudit.default.language topic of a howto configure document.
test Load a test page.
configure | config
The configuration file $HOME/.yudit/yudit.properties will be loaded into the editor
buffer.
After editing and saving the configuration file yudit should be restarted for the
changes to take effect.
howto configure
Load the HOWTO-configure.txt document if it exists. That document contains
information about editing the configuration file.
Various other topics are also available. These howto documents can be viewed on
yudit website too.
find string
Find a string in the document.
If the string contains spaces, double or single quotes can be used around it.
replace string replacement
Find a Unicode string and replace it with another string interactively.
If the string or replacement contains spaces, double or single quotes can be used
around them.
go | goto line [column]
Move the caret to the line and (optionally) to the column.
sedy Display the location of the encryption module add-on. Refer to yudit.syntaxpath
section of the howto configure document for details.
print [options]
Print the document, create a postscript file, or send the postscript file to a
program. For a full list of options, type print -h on the command area.
For instance print -e evince will send the postscript file to the program evince.
print -o out.ps will create a postscript file called out.ps.
When printing from inside the editor, the current font is used. Bitmap fonts are
also converted into postscript, but yudit will complain in the status area about
bad printing quality in such a case.
syntax Yudit provides a user interface to switch dictionaries and add a different
highlighting type. This can also be done in the command area. Type syntax -h for
help.
If the command is issued without an argument, the location of the spell-checker
add-on is displayed.
save [-yes] -e encoding filename
Save the current buffer. The preferred encoding is utf-8. If a keymap name is used
as an encoding, a transliterated text is written to the file.
Use the -yes option if you are sure you want to overwrite an existing file.
For a list of available encoding methods use the the command line tool: uniconv -h
open | load [-yes] -e encoding filename
Load a file to the editor buffer. The preferred encoding is utf-8. If a keymap
name is used as an encoding, the input file will be parsed by that keymap.
Use the -yes option if you do not mind losing unsaved changes of the current editor
buffer.
For a list of available encoding methods use the the command line tool: uniconv -h
SHORTCUTS
A variety of key shortcuts are available to make editing more convenient. Arrow-keys,
page-down, page-up, home and end work as expected. There is only insert mode in yudit.
Holding down the shift key while moving the caret selects the text.
In the command area the up and down keys serve as command history browser keys.
Some of the icons have tool-tips which can be used to check the shortcut.
The line-break button does not have a shortcut. It can be used to change the line-break
character to Unix/DOS/MAC(obsolete)/PS(a rarely used Paragraph Separator). Pressing this
button will modify the document in the buffer.
Function Keys
F1..F12 are used to switch between input methods. The assignment of the keys are
defined in the configuration property yudit.editor.inputs which can be changed
directly from inside yudit by the input assignment dialog.
Shift F1..F12 are used to switch between fonts. The assignment of the keys are
defined in the configuration property yudit.editor.fonts which can be changed via
editing yudit.properties. See howto configure command.
esc The escape key can be used to switch between editing and command mode.
ctrl|meta O
This shortcut copies an open-file command to the command area.
ctrl|meta S
This shortcut copies a save command to the command area.
ctrl|meta P
This shortcut copies a print command to the command area.
ctrl|meta W
This shortcut copies a print-preview command to the command area.
The default preview commend can be set via the configuration property
yudit.default.preview.command.
ctrl|meta Q
This shortcut copies a find command to the command area.
ctrl|meta U
Undo the last change to the document. There are cases where the change is broken
down into smaller changes, so you may need to press this more than once.
ctrl|meta R
Redo the changes that were undone by the Undo shortcut.
ctrl|meta T
Change the embedding of the document. Document embedding can be right-left,
neutral, and left-right. This is only a visual change, the document itself will not
be modified.
ctrl|meta D
Override the directionality of the input and the selected text.
The following markers are used: RLO (Right-Left Override), LRO (Left-Right
Override), PDF (Pop Directional Formatting).
Text under RL cursor for instance will be enclosed between RLO-PDF markers.
Note that yudit uses Unicode BiDi algorithm. Characters have inherent
directionality properties, so normally override is not needed.
It is useful if the script can be written both ways.
In case of Old Hungarian and Old Italic yudit provides software glyph mirroring
depending on inherent directionality of the character, the font directionality and
the directionality override.
See yudit.font.<fontname> in howto configure document to set up such a font.
ctrl|meta E
Override the embedding of the input and the selected text.
The following markers are used: RLE(Right-Left Embedding), LRE(Left-Right
Embedding), PDF(Pop Directional Formatting).
Text under RL-embedded cursor will be enclosed between RLE-PDF markers.
Embedding can be used to change the embedding level of a region of a text.
ctrl|meta Y
Give up embedding and directionality. The RLO-LRO/RLE-LRE and PDF markers will be
removed from the selected text.
ctrl|meta A
Make the font size smaller. Available font sizes are defined by the configuration
property yudit.editor.fontsizes which can be edited by hand.
ctrl|meta Z
Make the font size bigger. Available font sizes are defined by the configuration
property yudit.editor.fontsizes which can be edited by hand.
ctrl|meta N
This command copies the current highlighting mode into the command area.
ctrl|meta C
Copy selected text to CLIPBOARD. The X Window System has 2 clipboards. This
clipboard is the one that can be accessed only via keyboard shortcuts.
ctrl|meta X
Copy selected text to CLIPBOARD and delete it from the editor. In X Window System
there are 2 clipboards. This clipboard is the one that can be accessed only via
keyboard shortcuts.
ctrl|meta V
Paste the selected text from CLIPBOARD into the editor. In X Window System there
are 2 clipboards. This clipboard is the one that can be accessed only via keyboard
shortcuts.
If there is selected text in the editor, it will be replaced by the contents of the
CLIPBOARD.
The behavior of the other (XA_PRIMARY) X11 clipboard is different. The selected
text automatically goes to XA_PRIMARY clipboard and can be pasted by the middle
mouse button.
When editing encrypted sedy files XA_PRIMARY clipboard is read-only.
ctrl|meta H
Move the caret to the left.
ctrl|meta L
Move the caret to the right.
ctrl|meta J
Move the caret down.
ctrl|meta K
Move the caret up.
ctrl|meta B
Move to the previous page.
ctrl|meta F
Move to the next page.
ctrl|meta M
Erase the whole line.
ENVIRONMENT
The environment variable HOME should point to the user's home directory, where the yudit
configuration file (~/.yudit/yudit.properties) is kept.
Removing ~/.yudit/yudit.properties forces yudit to recreare the configuration file with
default properties.

AUTHOR
This program was written by gaspar@yudit.org (Gaspar Sinai), in Tokyo, and released on 10
November, 1997 as yutex. It was renamed to yudit on 8 December 1997.
Version 2.0 was released in January 2001. It came with internal font processing in an
effort to make it work in any environment. It was ported to Windows also.
Many thanks to Andrew Weeks at University of Bath for releasing his TrueType to postscript
(ttf2pfa) program which gave the inspiration of font conversion, rasterization and
printing in the 2.0 series.
When Linux started to support Unicode Yudit project became inactive.
In 2020 the project was revisited and a Macintosh port was added. In 2023 yudit.scale
property was introduced to upscale the GUI on high-resolution monitors.
