man mlterm (Commandes) - Multi Lingual TERMinal emulator on X

NAME

mlterm - Multi Lingual TERMinal emulator on X

SYNOPSIS

mlterm [options]

DESCRIPTION

mlterm is a multi-lingual terminal emulator written from scratch, which supports various character sets and encodings in the world and complex characters such as double width for East Asian, combining for Thai, Vietnamese, and so on, and bi-direction for Arabic and Hebrew. Indic scripts in ISCII encoding are experimentally supported using libind library. It also supports various unique feature such as anti-alias using FreeType, multiple XIM, multiple windows, scrollbar API, scroll by mouse wheel, automatic selection of encoding, daemon mode, and so on.

Supported encodings are: ISO-8859-[1-11], ISO-8859-[13-16], TIS-620 (same as ISO-8859-11), KOI8-R, KOI8-U, KOI8-T, GEORGIAN-PS, TCVN5712, VISCII, CP1251, CP1255, EUC-JP, EUC-JISX0213, Shift_JIS, Shift_JISX0213, ISO-2022-JP[1-3], EUC-KR, UHC, JOHAB, ISO-2022-KR, GB2312 (EUC-CN), GBK, GB18030, ISO-2022-CN, HZ, EUC-TW, BIG5, BIG5HKSCS, and UTF-8. If you have already set locale (for example LANG variable; see locale(7) for detail) mlterm will automatically select proper encoding.

OPTIONS

Note that bool is to be substituted by true or false.

-A, --aa(=bool): Use anti-aliased fonts. This option works only with Xft for now. The default is false.
-B, --sbbg=color: Specify a background color of a scrollbar. A valid value for color is a color name or a RGB value. The color name should be defined in rgb.txt or "color" configuration file. The RGB value's format should be "#RRGGBB".
-C, --iscii=language: Specify a language to be used in ISCII encoding. Valid names for language are Assamese, Bengali, Gujarati, Hindi, Kannada, Malayalam, Oriya, Punjabi, Roman, Tamil, and Telugu. Please read documents of the libind library for detail.
-D, --bi(=bool): Enable BiDi (bi-directional) processing on UTF8 encoding to support RTL (right-to-left) languages such as Arabic and Hebrew. The default is true.
-E, --km=encoding: Specify encoding. Valid encodings are listed in DESCRIPTION section above in this man page. AUTO makes mlterm determine the according according to the current locale (default AUTO).
-F, --sbfg=color: Specify a foreground color of a scrollbar. See --sbbg option for valid values.
-G, --vertical=mode: Specify vertical writing mode. cjk for RTL vertical writing and mongol for LTR one. The default is none which means horizontal writing mode.
-H, --bright=value: Brightness of background images in percent. See -p option for details of background images. The default is 100 (keep original).
-I, --icon=name: Specify a name to be used when a mlterm window is iconified. The default is "mlterm".
-J, --dyncomb(=bool): Enable dynamic character combining. "Dynamic" means that combining characters are stored in without combining but they are displayed using combined form. This affects calculation of column position, i.e., a pair of base character and combining character is counted to be two columns in this mode, while it is counted to be one column in the normal mode. Under this option, a (logical) column number and a character one-to-one correspondence. even for combining characters (though not for fullwidth characters; see -Z/--multicol option for handling of fullwidth characters). Thus, this mode enables you to use combining characters with softwares which do not support combining characters. When specifying this option, -m/--comb option should be used together. The default is false.
-K, --metakey=value: Specify a key to be interpreted as a META key. Valid values are: alt, meta, hyper, super, mod1, mod2, mod3, mod4, and none. The default is none.

See -k option also.

-L, --ls(=bool): Whether to use login shell or not. The default is false.
-M, --menu=path: Specify path name of the GUI configurator command. The default varies depending on compile-time options. By default, the path should be "/usr/local/libexec/mlconfig".

See GUI CONFIGURATOR section for detail.

-N, --name=name: Specify application name. The default is "mlterm".
-O, --sbmod=value: Specify the side to show a scrollbar. left for left side and right for right side. The default is none which turns off scrollbar.
-P, --ptys=value: Specify number of ptys (sessions) to be opened at start up. The default is 1. When more than one sessions was requested, only one screen(window) would be created. The sessions can be switched using the GUI Configurator or , in default key configuration, using Ctrl+F2/F3 key. To open a window foe each session, use -@/--screens option instead.

See MULTIPLE PTY section for detail.

-Q, --vcur(=bool): Change interpretation of cursor keys to be natural in vertical writing mode. This means that up and down arrow keys are treated as backward (left arrow in horizontal LTR) and forward (right arrow in horizontal LTR), respectively. In cjk -G/--vertical mode, left and right arrow keys are also treated as next line (down arrow in horizontal LTR) and previous line (up arrow in horizontal LTR), respectively, while vice versa in mongol mode. The default is false.
-R, --fsrange=range: Set acceptable range of font size. The format is "minsize-maxsize", where minsize and maxsize are font sizes in pixel (default 6-30). The GUI configurator and other means for setting fontsize should honor the range.
-S, --sbview=name: Select a type of scrollbar. See SCROLLBAR section below for details. The default is "simple" which means the built-in simple scrollbar.
-T, --title=name: Specify a title for a mlterm window. The default is "mlterm".
-U, --viaucs(=bool): Force to convert a selection (i.e., copy-and-paste strings) whose type is not UTF8_STRING to the current mlterm encoding via Unicode. See SELECTION section below for detail. The default is false.
-V, --varwidth(=bool): Use variable column width. You may want to use this option when you use proportional fonts. This option is automatically turned on when using ISCII encoding. The default is false.
-W, --sep=characterlist: Delimiter characters used for word selection, which are consulted when you double-clicked mlterm, to define what is a word. The default is " ,.:;/@")
-Y, --decsp(=bool): Use dynamically composed line drawing character set. This overrides DEC_SPECIAL in "font" configuration file. The default is false. This option is automatically turned on when Xft is used.
-Z, --multicol(=bool): Treat fullwidth characters (east Asian characters in most cases; which occupies two columns on the screen) as they occupy two logical columns. It is the de-facto standard way to handle fullwidth characters in east Asian terminal emulators (XFree86 xterm and kterm, cxterm, hanterm, rxvt, eterm) and other systems such as MS-DOS, PC-9801, and so on. In most fonts, the glyphs of fullwidth characters are designed assuming that their width are twice of normal characters and won't display correctly without this option. The default is true.
-0, --crbg=color: Specify background color for cursor (default is same to foreground color). Valid values for color are color names defined in rgb.txt and "color" configuration file and color rgb string whose format is "#RRGGBB".
-1, --wscr=value: Specify actual window width, by percentage against calculated value by multiplying font width by column number. This is useful when you use a proportional font which includes some glyphs with exceptionally large width, i.e., much larger "maximum width" than your expectation. The default is 100.
-2, --hscr=value: Specify actual screen height, like -1/--wscr does for width. The default is 100.
-3, --contrast=value): Contrast of background image in percent. See -p option for details of background image. The default is 100.
-4, --gamma=value): Gamma of background image in percent. See -p option for details of background image. The default is 100.
-5, --big5bug(=bool): Enable a workaround for Big5 CTEXT bugs (which had been existed until XFree86 4.1.0). This affects Big5 selections (i.e., copy-and-paste strings) in COMPOUND_TEXT format which mlterm sends. The default is false.
-6, --stbs(=bool): Don't exit backscroll mode when console applications output something. The default is false.
-7, --bel=mode: Behavior when BEL (0x07) is received. sound for beep and visual for blanking screen. The default is none which ignores BEL.
-8, --88591(=bool): Use ISO8859-1 fonts for US-ASCII part of various encodings.
-9, --crfg=color: Specify foreground color for cursor (default is same to background color). Valid values for color are color names defined in rgb.txt and "color" configuration file and color rgb string whose format is "#RRGGBB".
-$, --mc=value: Doubleclick/tripleclick interval in millisecond. The default is 250.
-&, --borderless=bool: Asks the window manager to use no decorations at all. Warning: You will not be able to resize the window. You probably want to use --geometry as well. The default is false.
-@, --screens=value: Specify number of screens (sessions) to be used in start up. The default is 1. Note that when one of these screens are closed, sessions which were connected to the screens do not immediately killed. See MULTIPLE PTY section for details.
-*, --type=value: Specify the rendering engine to be used to draw fonts. xcore is conventional X11 core font mechanism and xft means Xft mechanism. The default is xcore.
-%, --logseq=bool: Enable logging. Contents of stream received by mlterm will be logged under ~/.mlterm/. This option is mainly intended to be used for debugging purposes. The default is false. Note that % should be escaped to be supplied as a command line option on most shells.
-#, --initstr=value: Specify a string to be automatically sent after initialization of session. The value normally will be parsed by a shell. See -e option to execute other application at start-up time.
-a, --ac=value: Specify number of columns to be occupied by a Unicode's "EastAsianAmbiguous" character. The default is 1 and some of Asian people may want to specify 2. See Unicode Standard Annex (UAX) #11 East Asian Width found at Unicode web site for details.
-b, --bg=color: Specify background color (default white). Valid values for color are color names defined in rgb.txt and "color" configuration file and color rgb string whose format is "#RRGGBB".
-c, --cp932(=bool): Use CP932 mapping table to convert from JIS X 0208 to Unicode when displaying JIS X 0208 characters using Unicode font in anti-alias (Xft) mode. This is useful when you use proprietary Japanese true type fonts which are intended to be used with Microsoft Windows, with mlterm with encodings (such as EUC-JP, Shift_JIS, ISO-2022-JP, and so on) which contain JIS X 0208 as a coded character set.

The reason is, such proprietary fonts may have glyphs only for Unicode code points into which JIS X 0208 code points are converted using CP932 mapping table. (CP932 is a name of mapping table which is used by Microsoft to convert from Shift_JIS [plus Microsoft private extended characters] into Unicode. In Unicode's point of view, CP932 is a name of encoding which is similar to Shift_JIS and is used by Japanese version of Microsoft Windows.) If you use such fonts for encodings such as EUC-JP and Shift_JIS with JIS0208.TXT mapping table which mlterm adopts as the standard, a few characters are mapped into Unicode code points where the fonts don't have glyphs.

Both of CP932.TXT and JIS0208.TXT mapping tables are supplied by Unicode Consortium, though they are regarded to be obsolete.

The default is true.

-d, --display=string: Specify X display to connect with.
-e program [ arguments ... ]: Invoke the command in the mlterm window. This option must be the last option on the command line.
-f, --fg=color: Foreground color (default black). Valid values for color are color names defined in rgb.txt and "color" configuration file and color rgb string whose format is "#RRGGBB".
-g, --geometry=geometry: Specify size and position of the window; see X(7).
-h, --help(=bool): Show help messages.
-i, --xim(=bool): Whether to use XIM (X Input Method). Most east Asian people will want to enable this option. Other people can also safely enable this. The default is true. The name of the XIM server to be connected is specified by standard way (i.e., XMODIFIERS environmental variable).
-j, --daemon=value: Start as a daemon process. Possible =values are "blend" and "genuine". See the chapter of DAEMON MODE for details.
-k, --meta=mode: Behavior of META key. esc for sending ESC and none for ignoring META key. The default is 8bit which sets the most significant bit.

See -K option also.

-l, --sl=value: Specify number of lines of backlog. The default is 128.
-m, --comb(=bool): Enable combining characters by overstriking glyphs (recommended for TIS-620, TCVN5712, and UTF-8). Note that fonts which contain combining characters which extend backward cannot be used, since mlterm does combine characters by controlling the writing positions. The default is true.
-n, --noucsfont(=bool): Use non-Unicode fonts even when mlterm encoding is UTF-8. Useful when you don't have ISO10646-1 fonts and you want to use UTF-8 encoding. The default is false.
-o, --lsp(=value): Specify number of extra pixels between lines. The default is 0.
-p, --pic=path: Path for a wallpaper (background) image. Note that the wallpaper cannot be used with transparent background.
-q, --extkey(=bool): Enable extended keys for backscroll mode. The default is false. Extended scroll keys are SCROLL_UP, up arrow, and "k" (for scrolling one line backward) and SCROLL_DOWN, down arrow, and "j" (for scrolling one line forward). Please note that concrete keys for symbols of SCROLL_UP and SCROLL_DOWN are specified in key configuration file. Only keys of PAGE_UP and PAGE_DOWN (which are specified in key configuration file) are available by default.
-r, --fade=ratio: Specify fading ratio for unfocused windows. 100 means no fading and 0 means darkest. The default is 100
-s, --sb(=bool): Whether to use a scrollbar. The default is true.
-t, --transbg(=bool): Whether to enable transparent background. Note that transparent background cannot be used with wallpaper. The default is false.
-u, --onlyucsfont(=bool): Use Unicode fonts even when mlterm encoding is not UTF-8. Useful when you have ISO10646 fonts but you don't have other fonts and want to use non-UTF-8 encodings. Note that conversion to Unicode is lossy. i.e. if mlterm encoding is not a subset of Unicode like ISO-2022-JP-2 or EUC-TW, characters which are regarded as a same character in Unicode will be displayed with the same glyph and cannot be distinguished.

The default is false.

-v, --version Show version information.
-w, --fontsize=value
Specify font size in pixel. The default is 16.
-x, --tw=value
Specify tab width. The default is 8.
-y, --term=string
Specify terminal type, i.e., the value of TERM variable. Corresponding definition must be exist in terminfo/termcap database and the contents should fits to the behavior of mlterm. Since mlterm is designed to generally behave like kterm, values which works for kterm may be used. The default is xterm.

To use full features of mlterm, it's recommended to install the definition of mlterm which distributed with source and choose "mlterm" as a value of TERM.

-z, --largesmall=size: Specify the step of changing font size in pixel when you pushed "Font size larger" or "Font size smaller" button on GUI configurator. The default is 1.
--iconpath=path: Specify the file to be used as a window icon.

GUI CONFIGURATOR

Pushing control key and mouse button 3 invokes GUI configurator (mlconfig). It can modify encoding, foreground and background color, tab size, backlog size, font size, usage of combining character, and so on.

GUI configurator has five pages (Encoding, Appearance, Color, Scrollbar, and Others), OK/Apply/Cancel buttons, and three special buttons.

Note this feature needs GTK+ 1.2 or later.

Buttons

There are buttons which is independent from OK/Apply/Cancel buttons.

OK/Apply/Cancel: OK button applies the modified configuration to the current mlterm session, saves it to "~/.mlterm/main" configuration file, and quits the GUI Configurator. Apply button just applies the modified configuration to the current mlterm session.
Font size (Larger and Smaller): Change font size.
PTY List: One process of mlterm may have multiple sessions and screens. The sessions may or may not have corresponding screen, i.e., the number of sessions can be more than the number of screens. Such situation can be achieved by using -P/--ptys option or closing a part of multiple screens from -@/--screens option. In such case, the screen-less session can be designated to one of screens by choosing the session (pty) from this list and push "select" button.
Full reset: Reset internal status.

CONFIGURABLE MENU

Pushing control key and mouse button 1 invokes configurable menu displayer (mlterm-menu). It displays a menu with items such as "Larger Font" or "UTF-8 encoding". Though a default menu definition is supplied, you can freely define menu items by writing a menu configuration file. See Menu Configuration File section for detail.

Note this feature needs GTK+ 1.2 or later.

MULTIPLE XIM

mlterm can use multiple XIM (X Input Method) servers. The current XIM is specified by the GUI configurator. Using this feature you can input multiple complex languages such as Japanese and Korean. Locale to be used for communication with XIM can also be specified for each XIM. In the GUI configurator, you can choose one of registered pair of XIM and its locale or you can input your favorite XIM and its locale.

The locale for XIM is only used for communication with the XIM and is not related to the current mlterm locale. You have to properly configure the XIM locale only when your XIM has preference on the locale of XIM client (i.e., mlterm in this case). mlterm automatically convert the inputed string into proper encoding and you don't have to care about it.

Of course the initial XIM is chosen by using standard configuration, i.e., using XMODIFIERS environmental variable. See X(7) for detail on XIM and XMODIFIERS variable.

DAEMON MODE

When invoked with -j/--daemon command line option, mlterm starts to listen on a unix domain socket and accept requests from mlclient.

With blend mlterm will exit when the final terminal window is closed. But with genuine, mlterm will disconnect from X server windows and continues to work. In latter case, it's possible to stop and restart a X server and revive the lasting sessions on mlterm.

SCROLLBAR

mlterm supports scrollbar API so that users can develop scrollbar libraries with arbitrary look and feel. The scrollbar libraries can be used by putting the libraries at the specified directory (determined on the compilation process) and invoke mlterm with -s -S name option. Scrollbar libraries named "sample", "sample2", "athena", "motif", "mozmodern", and "next" are supplied.

ANTI-ALIAS

mlterm can use True Type fonts using -A option via FreeType library when it has been compiled with anti-alias option.

Note this feature needs XFree86 4.0.2 or above and FreeType 2.0.2 or above.

WALLPAPER

mlterm can use background image (as known as wallpaper), by using -p/--pic option. You can also specify the brightness of the image by using -H/--bright option.

Note this feature needs imlib or gdk-pixbuf.

MULTIPLE PTY

This is one of most unique features of mlterm. The number of windows can be specified using -P option. Typing control + F1 opens another window which shares the same process. The maximum number of windows depends on your platform. Mostly it is 32 or 64.

BACKSCROLL MODE

mlterm enters into backscroll mode by typing Shift + up or Shift + PageUp key. In the mode, you can use the following keys.

j or Down: Scroll down one line.
k or Up: Scroll up one line.
d or PageDown: Scroll down one page.
u or PageUp: Scroll up one page.
Shift + space: Initialize XIM.
Shift + Insert: Insert selection.
Control + F1: Open a new pty window.
keys defined in key configuration file: PAGE_UP, PAGE_DOWN, SCROLL_UP, and SCROLL_DOWN keys are defined in the file.
other keys: Exit from the backscroll mode.

Please note that keys other than PAGE_UP and PAGE_DOWN in key configuration file are available only when you used -q/--extkey command option.

SELECTION

Selection is a mechanism to be used for copy-and-paste in X Window System. Thus, this section describes on so-called copy-and-paste.

There are many encodings in the world. Though copy-and-paste needs sender and receiver and each of them can use one of various encodings, mlterm is designed to be able to receive characters from various encodings as much as possible.

There are two internationalized types of selection. One is COMPOUND_TEXT is the another is UTF8_STRING. COMPOUND_TEXT is ISO2022-based and can distinguish character sets which a character belongs to. However, the character sets which COMPOUND_TEXT supports are limited to ISO8859-* and East Asian character sets. On the other hand, UTF8_STRING is Unicode-based and can express all characters from Unicode character set. However, it cannot distinguish characters from different character sets which share one codepoint in Unicode, which can be a problem especially for CJK Han Ideogram (in other words, Kanji, Hanji, or Hanja). Note that UTF8_STRING is rather new and can be used only with XFree86.

Though the receiver of copy-and-paste can request the preferable type of selection, the sender may not support the requested type. Thus mlterm has to be able to process both of COMPOUND_TEXT and UTF8_STRING.

On the other hand, encodings supported by mlterm (see DESCRIPTION section for detail) are classified into four categories;

(a) Unicode itself: UTF-8.
(b) subset of Unicode and ISO-2022-compliant: "Subset of Unicode" means that Unicode supports round-trip compatibility for the encoding, i.e., the conversion of the encoding --> Unicode --> the encoding doesn't lose any information. "ISO-2022-compliant" means that the encoding can be regarded as a subset of ISO-2022 where a part of ISO-2022 control codes and escape sequences are not supported. Many popular encodings belong to this category such as ISO-8859-*, EUC-*, ISO-2022-KR, TIS-620, TCVN5712, and so on.
(c) subset of Unicode and non-ISO-2022-compliant: Some of popular encodings such as Shift_JIS, Big5, GBK, GB18030, Johab, and so on belongs to this category.
(d) not subset of Unicode: ISO-2022-JP, ISO-2022-JP-2, ISO-2022-JP-3, EUC-TW, and so on. All of them are ISO-2022-compliant.

Now the behavior of mlterm can be explained.

-------------------------------------------------------
encoding received selection  how to process?
-------------------------------------------------------
   a     COMPOUND_TEXT       convert to Unicode
   a     UTF8_STRING         no need for conversion
   b     COMPOUND_TEXT       user preference *1
   b     UTF8_STRING         convert to the encoding *2
   c     COMPOUND_TEXT       user preference *1
   c     UTF8_STRING         convert to the encoding *2
   d     COMPOUND_TEXT       no need for conversion *3
   d     UTF8_STRING         convert to the encoding *2
-------------------------------------------------------

*1 Characters from unsupported character sets (i.e., characters which cannot be expressed in the mlterm encoding) may appear in the selection (received copy-and-paste string). If you want to receive characters which are equivalent to characters which are supported in the current mlterm encoding (i.e., characters which share the same codepoint in Unicode), you can use -U (or --viaucs) option. Otherwise, these characters are pasted into mlterm using ISO-2022 escape sequence (when mlterm encoding is category b). Note such ISO-2022 escape sequences are illegal in the current mlterm encoding and the application software will need special feature to treat them properly, though it is displayed well in mlterm. When mlterm encoding is category c, such characters are simply ignored (when -U option is not enabled).

*2 Characters which cannot be converted into mlterm encoding are simply ignored.

*3 Characters from unsupported character sets will be pasted into mlterm using ISO-2022 escape sequence.

CONFIGURATION

mlterm loads configuration files of "main", "font", "vfont", "tfont", "aafont", "vaafont", "taafont", "color", "key", "termcap", and "xim" on start up. "menu" configuration file is loaded by the configurable menu displayer (mlterm-menu). See the section of CONFIGURABLE MENU for detail.

Configuration files for one user are to be located in "~/.mlterm/" directory, while location for configuration files for all users depends on the compilation option. Possible locations are "/etc/", "/etc/X11/", "/usr/X11R6/lib/X11/mlterm/", and so on.

The names and the roles of configuration files are:

main: Main configuration items which can be overridden by command line options.
font: Configurations for ordinary X fonts.
vfont: Configurations for ordinary X fonts of variable column width.
tfont: Configurations for ordinary X fonts of vertical writing.
aafont: Configurations for anti-alias Xft fonts.
vaafont: Configurations for anti-alias Xft fonts of variable column width.
taafont: Configurations for anti-alias Xft fonts of vertical writing.
color: Designate concrete RGB values for color names.
key: Key definitions for special features of mlterm.
termcap: Define mlterm's behaviors which affects terminfo and termcap definition.
xim: Define preset locales for X Input Methods which are shown in the GUI configurator. Of course you can input XIM names and locales for the GUI configurator which are not listed in this configuration file.

Font Configuration Files

The font configuration files "font", "vfont", "tfont", "aafont", "vaafont", and "taafont" have the following keys.

DEC_SPECIAL=fonts
ISO8859_n=fonts
TIS620=fonts
VISCII=fonts
KOI8_R=fonts
KOI8_U=fonts
TCVN5712=fonts
JISX0201_ROMAN=fonts
JISX0201_KATA=fonts
JISX0208_1978=fonts
JISX0208_1983=fonts
JISX0208_1990=fonts
JISX0213_2000_1=fonts
JISX0213_2000_2=fonts
KSX1001_1997=fonts
UHC=fonts (not used)
JOHAB=fonts (not used)
GB2312_80=fonts
GBK=fonts
BIG5=fonts
HKSCS=fonts
CNS11643_1992_n=fonts
ISO10646_UCS4_1=fonts
ISO10646_UCS4_1_BIWIDTH=fonts

Specify fonts for corresponding character sets. The format is different between "font", "vfont" "tfont" files and "aafont", "vaafont" "taafont" files.

In "font", "vfont", "tfont" files, "font" is specified in "NAME:PERCENT;SIZE,NAME:PERCENT;SIZE,NAME:PERCENT;..." format where "SIZE" is font size in pixel, and "NAME" is XLFD or alias names of X fonts. If the first "NAME" contains "%d", it is replaced by an appropriate font size number. ":PERCENT" is multiplied by font size and decides character width of a font. If ":PERCENT" is omitted, max font width is used for it.

In "aafont", "vaafont", "taafont" files, "font" is specified in "FAMILY-ENCODING:PERCENT;SIZE,FAMILY-ENCODING:PERCENT;SIZE,FAMILY-ENCODING:PERCENT;..." format. The first pair of FAMILY and ENCODING specifies the default font and the others with SIZE are for specific sizes. ":PERCENT" is multiplied by font size and decides character width of a font. If ":PERCENT" is omitted, 'W' width is used for it.

encoding_BOLD=fonts: Specify boldface fonts.

Color Configuration File

The color configuration file "color" has the following key.

COLORNAME=RGB: Assign a concrete color for the name COLORNAME. Default colors used by mlterm are red, green, yellow, blue, magenta, cyan, and white. and can be overridden here.

For hilighted colors, a name with "hl_" prefix will be automatically searched. i.e. for bold read character, "hl_red" is searched instead of "red".

The format of RGB is either "RRRR-GGGG-BBBB" (where RRRR, GGGG, and BBBB are hexadecimal value from 0 to ffff) or "#RRGGBB" (where RR, GG, and BB are hexadecimal value from 00 to ff).

If mlterm failed to parse a entry, the color will be regarded as black.

XIM Configuration File

The X Input Methods configuration file "xim" has the following format

XIM=locale

where XIM is XIM name and locale is locale name used for communication with the XIM server. For example,

kinput2=ja_JP.eucJP
Ami=ko_KR.eucKR
xcin-zh_CN.GB2312=zh_CN.GB2312

These settings are used to create list of XIMs by the GUI configurator. Though a XIM which is not listed in this file can't be selected from the list, it can be selected by specifying its name directly.

Feature Key Configuration File

The feature key configuration file "key" has the following format.

KEY=FEATURE

Here, the format for KEY is "(MASK+)KEY", where MASK is one of Control, Shift, and Mod. You can specify multiple "MASK+"s. You can search spellings of KEY by using xev(1) command or searching keysym macros from /usr/X11R6/include/X11/keysymdefs.h (or the equivalent file in your X11 include directory) and omit the prefix XK_. Double quotation marks are not needed.

FEATURE is one of IM_HOTKEY, EXT_KBD, OPEN_SCREEN, NEW_PTY, OPEN_PTY, NEXT_PTY, PREV_PTY, PAGE_UP, PAGE_DOWN, SCROLL_UP, SCROLL_DOWN, INSERT_SELECTION, "STRING", or "proto:STRING".

IM_HOTKEY: Switch conversion mode of m17n library and kdb input methods. (default UNUSED)
EXT_KBD: Activate or deactivate kbd input method. (This feature was obsoleted by IM_HOTKEY)
OPEN_SCREEN: Open new pty in new screen (default Ctrl+F1).
NEW_PTY: Same as OPEN_SCREEN (obsoleted).
OPEN_PTY: Open new pty in current screen (default Ctrl+F2).
NEXT_PTY: Switch to a next free pty (default Ctrl+F3).
PREV_PTY: Switch to a previous free pty (default Ctrl+F4).
PAGE_UP: Start backscroll mode and scroll up one page (default Shift+Prior).
PAGE_DOWN: Scroll down one page. (default Shift+Next).
SCROLL_UP: Start backscroll mode and scroll up by one line (default Shift+Up). Note this key is enabled only when -q/--extkey option is used.
SCROLL_DOWN: Scroll down one line (default Shift+Down). Note this key is enabled only when -q/--extkey option is used.
INSERT_SELECTION: Insert selection (default Shift+Insert).
"STRING": The specified string is issued when the KEY key is pressed. Double quotation marks are required around the STRING. Note that you cannot control the status of mlterm by sending terminal control codes such as "\x1b]5379;encoding=utf8\x0a" because the code sequence will be caught by your shell (or something running on it). To deliver control sequences to mlterm directly, use "proto:STRING" instead.
"proto:STRING": The specified string is assumed to mlterm's original control sequence. A list of sequences should be found in doc/en/PROTOCOL. For example, "proto:encoding=utf8" means changing the current character encoding to UTF-8.

Terminal Behavior Configuration File

This configuration file determines the behaviors of mlterm that should match the definition of terminfo and termcap. In principle, this file should not be edited and, instead, you should choose a proper value for TERM variable (i.e., proper terminfo/termcap definition) which meets mlterm's behavior. (Since mlterm' can behave as a xterm/kterm to some extent, TERM=kterm / TERM=xterm should give acceptable results.) However, sometimes you may not want to edit your terminfo and termcap. Your software may don't understand terminfo nor termcap, or your terminfo/termcap entry is shared by several terminal emulators and changing it will break other terminals. In such cases, you can configure mlterm so that it works well on existing terminfo/termcap definitions on your systems. This is also useful for distributors of operating systems (like Debian) with strict policy of terminal emulators' behaviors.

You can define the behaviors of mlterm for each value of TERM variable, so that you don't need to edit termcap file each time you login into other systems and use different value of TERM variable by -y option. You can also specify the default behavior when TERM variable is different from all of specified TERM names in the termcap file.

The grammar of this configuration file is resemble to the grammar of termcap entries. First, one or more name(s) of TERM is written. Multiple names are connected with vertical line character '|'. Special name '*' is for default. Then colon ':' comes, and keys are written separated by colons. Configuration(s) for other TERM will follow after new line.

Followings are available keys for each TERM value.

kD=sequence: Specify sequence to be outputted when Delete key is pushed (default \E[3~).
kb=sequence: Specify sequence to be outputted when BackSpace key is pushed (default ^?).
kh=sequence: Specify sequence to be outputted when HOME key is pushed (default \EOH).
@7=sequence: Specify sequence to be outputted when END key is pushed (default \EOF).
ut: Specify the way how the screen is erased by control codes. If ut is written in the termcap file, charcells are painted by the current background color when erased; otherwise the charcells are painted by the initial background color. Default is non-ut behavior.

The following special characters can be used to specify sequence in keys of kD/kb/kh/@7.

\E: ESC code (0x1b).
^?: DEL code (0x7f).
^A, ^B,...: Corresponding control code (0x01 - 0x1a).

Menu Configuration File

This configuration file defines the menu displayed by the configurable menu displayer mlterm-menu. See CONFIGURABLE MENU section for detail.

FILES
