MLTERM(1) General Commands Manual MLTERM(1) 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, Viet- namese, and so on, and bi-direction for Arabic and Hebrew. Indic scripts are experimentally supported. 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, ISCII_(AS- SAMESE|BENGALI|GUJARATI| HINDI|KANNADA|MALAYALAM|ORIYA|PUNJABI|TAMIL|TEL- UGU), VISCII, CP125[0-8], CP874, 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 lo- cale(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 or cairo 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", "#RRGGBBAA", "rgb:RR/GG/BB" or "rgba:RR/GG/BB/AA". -C, --ctl(=bool) Enable complex text layouting on UTF8 encoding to support indic scripts and RTL (right-to-left) languages such as Arabic and Hebrew. The default is true. (If mlterm -v outputs "no-indic" or "no-bidi", indic scripts or RTL languages are not supported.) -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 de- tails 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 software which does not support com- bining characters. 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 de- fault is none. See -k option also. -L, --ls(=bool) Whether to use login shell or not. The default is false. -M, --im= input method : [ arguments ... ] Specify an input method. Examples: --im=xim Use XIM with the default XIM server specified by standard way (i.e., XMODIFIERS environmental variable). --im=xim:Ami Use XIM with Ami on the system locale. --im=xim:kinput2:ja_JP.EUC-JP Use XIM with kinput2 on ja_JP.EUC-JP locale. --im=kbd:arabic Use keyboard mapping input method in Arabic. --im=kbd:hide:arabic Use keyboard mapping input method without showing the status screen. "kbd" input method converts US keyboard characters to other keyboard layouts. It is assumed to be used in environments with limited functionality, such as older OSs that support few keyboard layouts. Available values for "kbd" input method argument are "arabic", "hebrew", "de", "fr", "es", "pt", "jp106", "isciiassamese", "isciibengali", "isciigu- jarati", "isciihindi", "isciikannada", "isciimalayalam", "isciioriya", "isciipunjabi", "isciitamil" and "isciitelugu". --im=uim Use uim with the default conversion engine. --im=uim:prime Use uim with prime conversion engine. --im=m17nlib:ru Use m17n library in Russian. --im=m17nlib:or:itrans Use m17n library in Oriya using ITRANS method. --im=scim Use SCIM. --im=ibus Use IBus with the default conversion engine. --im=ibus:anthy Use IBus with anthy conversion engine. --im=fcitx Use Fcitx. --im=canna Use Canna. --im=wnn Use Freewnn. --im=wnn:foo.bar Use Freewnn with jserver at foo.bar host. (JSERVER environ- mental variable is also available.) --im=skk Use SKK. --im=skk:dict=foo.bar:utf8,sskey=\x3b Use SKK with the use of utf8 skk server at foo.bar host and semicolon key as sticky shift key. (SKK_DICTIONARY and SKK_STICKY_SHIFT_KEY environmental variable are also avail- able.) --im=iiimf Use IIIMF in the system language. --im=iiimf:ar Use IIIMF in Arabic. --im=iiimf:ja:CannaLE Use IIIMF in Japanese using CannaLE language engine. --im=none Don't use input method. -N, --name=name Specify application name. (WM_CLASS property) The default is "ml- term". --role=role Specify application role. (WM_WINDOW_ROLE property) The default is undefined. -O, --sbmod=value Specify the side to show a scrollbar. left for left side and right for right side. none turns off a scrollbar. autohide shows a scrollbar only if mouse pointer is at the right edge of the screen. The default is left. -Q, --vcur(=bool) Change interpretation of cursor keys to be natural in vertical writ- ing 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 hori- zontal LTR) and previous line (up arrow in horizontal LTR), respec- tively, while vice versa in mongol mode. The default is true. -R, --fsrange=range Set acceptable range of font size. The format is "minsize-maxsize", where minsize and maxsize are font sizes in pixel (default 1-10000). 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 de- tails. 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". --locktitle(=bool) Lock the title for a mlterm window. If a title is locked then OSC 0, 1 and 2 esc sequences to change it are ignored. The default is false. -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. 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 de- fault is " ,.:;/|@()[]{}") -X, --alpha=value Alpha in pseudo or true transparent. The default is 255. -Y, --decsp(=bool) Use dynamically composed line drawing character set of DEC special. The default is false. This overrides DEC_SPECIAL in "font" configu- ration file, while DEC_SPECIAL in "aafont" (for Xft or cairo) is al- ways overridden. -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 char- acters 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 charac- ters are designed assuming that their width are twice of normal characters and won't display correctly without this option. The de- fault 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 rgb string whose format is "#RRGGBB", "#RRGGBBAA", "rgb:RR/GG/BB" or "rgba:RR/GG/BB/AA". -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 exception- ally large width, i.e., much larger "maximum width" than your expec- tation. In vertical mode this option changes actual window height. 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 un- til XFree86 4.1.0). This affects Big5 selections (i.e., copy-and- paste strings) in COMPOUND_TEXT format which mlterm sends. The de- fault is false. -6, --stbs(=bool) Don't exit backscroll mode when console applications output some- thing. The default is false. -7, --bel=mode Behavior when BEL (0x07) is received. sound for beep , visual for blanking screen and sound|visual for the both. 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 rgb string whose format is "#RRGGBB", "#RRGGBBAA", "rgb:RR/GG/BB" or "rgba:RR/GG/BB/AA". -$, --mc=value Doubleclick/tripleclick interval in millisecond. The default is 250. -%, --logseq(=bool) Enable logging. Contents of stream received by mlterm will be logged under ~/.mlterm/. This option is mainly intended to be used for de- bugging purposes. The default is false. Note that % should be es- caped to be supplied as a command line option on most shells. -&, --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, ses- sions 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. xft means Xft mechanism and cairo means cairo mechanism. The default is cairo. On platforms except X11, it is always xcore. (If mlterm -v outputs "no-xft" or "no-cairo", xft or cairo is unavailable.) -#, --initstr=value Specify a string to be automatically sent after initialization of session. The value normally will be parsed by a shell. See -e op- tion to execute other application at start-up time. -a, --ac=value Specify number of columns to be occupied by a Unicode's "East- AsianAmbiguous" character. The default is 1 except "ja" locale where the default is 2. Some of asian people may want to specify 2. See Unicode Standard Annex (UAX) #11 East Asian Width found at Uni- code 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 rgb string whose format is "#RRGGBB", "#RRGGBBAA", "rgb:RR/GG/BB" or "rgba:RR/GG/BB/AA". -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 Xft or cairo mode. This is useful when you use proprietary Japanese true type fonts which are intended to be used with Microsoft Windows, with ml- term 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 Uni- code code points into which JIS X 0208 code points are converted us- ing 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).

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 con- nected is specified by standard way (i.e., XMODIFIERS environmental variable). -j, --daemon=value Start as a daemon process. Note that mlclient is executed if a dae- mon process has already started. Possible =values are "blend" and "genuine". See the chapter of DAEMON MODE for details. (If mlterm -v outputs "no-daemon", this option is unavailable.) -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 or "unlimited". Over 65535(0xffff) is regarded as "unlimited". 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 com- bining characters which extend backward cannot be used, since mlterm does combine characters by controlling the writing positions. This option is automatically turned on when using --dyncomb option. 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 en- coding. 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 pseudo transparent background. (If mlterm -v outputs "no-image", this option is unavailable.) -r, --fade=ratio Specify fading ratio for unfocused windows. 100 means no fading and 0 means darkest. The default is 100 -s, --mdi(=bool) Whether to use multiple document interface. The default is true. If you disable this option, scrollbar and screen separation are un- available. -t, --transbg(=bool) Whether to enable pseudo transparent background. Note that pseudo 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 can- not 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. The de- fault is xterm.

GUI configurator has six pages (Encoding, Font, Background, Color, Scroll- bar, and Others), OK/Apply/Cancel buttons, and four special buttons. Note this feature needs GTK+ 2.x or later. Encoding page Encoding-related configurations are located in this page. Note that con- figurations will be enabled when you push Apply button. Encoding Specify encoding. (-E, --km) Auto detect Whether to detect appropriate character encoding automatically. (--auto) Encoding list Specify character encodings detected automatically. (--ade) Input Method Specify which input method to be used. (-M, --im) XIM: XIM Server Specify the name of XIM server to be connected. You can in- put from your keyboard or you can choose one of registered XIM servers. This doesn't have equivalent command option. See the section of XIM Configuration File for registration of XIM servers. XIM locale Specify the name of the locale to be used for connection to the XIM server. Popular XIM servers usually have acceptable locales to be used for connection. If you choose registered XIM server in Input Method, this will be set automatically.

Apply button just applies the modified configuration to the current mlterm session. Font size (Larger and Smaller) Change font size. Full reset Reset internal status. Snapshot Snapshot the screen and save it to ~/.mlterm/*.snp. SCP Transfer a file via SCP. 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 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. 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+ 2.x 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 multi- ple 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 con- figurator, 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 compi- lation process) and invoke mlterm with -s -S name option. Scrollbar li- braries named "sample", "sample3", "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 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 can be speci- fied using --maxptys option. 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. u or PageUp Scroll up one page. d or PageDown Scroll down one page. keys defined in key configuration file Shortcut keys work the same way as in normal mode. (INSERT_SELEC- TION, INSERT_CLIPBOARD, RESET and COPY_MODE exit from the backscroll mode.) other keys Exit from the backscroll mode. 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 dis- tinguish character sets which a character belongs to. However, the charac- ter 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 code- point 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 compati- bility 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, Jo- hab, 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 can- not be expressed in the mlterm encoding) may appear in the selection (re- ceived 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 ml- term using ISO-2022 escape sequence (when mlterm encoding is category b). Note such ISO-2022 escape sequences are illegal in the current mlterm en- coding 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 en- abled). *2 Characters which cannot be converted into mlterm encoding are simply ig- nored. *3 Characters from unsupported character sets will be pasted into mlterm using ISO-2022 escape sequence. COPY MODE mlterm enters into copy mode by typing Shift + Control + Return key. In the mode, you can move in the screen including backlog, select region and copy it by the following keys. j or Down Scroll down one line. k or Up Scroll up one line. l or Right Move right. h or Left Move left. u or PageUp Scroll up one page. d or PageDown Scroll down one page. / Input search string. (forward) ? Input search string. (backward) Control+g Cancel search string. Space or Return Start or finish selection. Mod+Space or Mod+Return Start rectangle selection. Escape or q Exit from the copy mode. Any other keys Stop selection. CONFIGURATION mlterm loads configuration files of "main", "font", "vfont", "tfont", "aa- font", "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/" direc- tory, 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 op- tions. 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 Xft or cairo fonts. vaafont Configurations for Xft or cairo fonts of variable column width. taafont Configurations for Xft or cairo 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 defini- tion. xim Define preset locales for X Input Methods which are shown in the GUI configurator.

The format is dif- ferent between "font", "vfont" "tfont" files and "aafont", "vaafont" "taafont" files. In "font", "vfont", "tfont" files, "font" is specified in "NAME:PER- CENT" format where "SIZE" is font size in pixel, and "NAME" is XLFD or alias names of X fonts. If "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 WEIGHT SLANT SIZE:PERCENT" format. ":PERCENT" is multiplied by font size and decides character width of a font. If ":PERCENT" is omitted, 'M' width is used for it. mlfc command generates ~/.mlterm/aafont automatically. charset_BOLD=font Specify boldface fonts. charset_ITALIC=font Specify italic fonts. charset_BOLD_ITALIC=font Specify bold-italic fonts. U+XXXX-XXXX=font Specify which fonts to use for unicode ranges except U+00-7f. 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 black, red, green, yellow, blue, magenta, cyan, and white. and can be overridden here. For highlighted colors, a name with "hl_" prefix will be automati- cally searched. i.e. for bold red characters, "hl_red" is searched instead of "red". 17 - 230 and 232 - 255 in 256 colors can be also overridden. The format of RGB is either "RRRR-GGGG-BBBB" (where RRRR, GGGG, and BBBB are hexadecimal value from 0 to ffff), "#RRGGBB", "#RRGGBBAA", "rgb:RR/GG/BB" or "rgba:RR/GG/BB/AA"(where RR, GG, and BB are hexa- decimal 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, Mod1, Mod2, Mod3, Mod4, Mod5, Mod and Alt. 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. You can specify Button1, Button2, Button3, Button4 or Button5 as KEY. FEATURE is one of IM_HOTKEY, EXT_KBD, OPEN_SCREEN, NEW_PTY, OPEN_PTY, NEXT_PTY, PREV_PTY, VSPLIT_SCREEN, HSPLIT_SCREEN, CLOSE_SCREEN, NEXT_SCREEN, PREV_SCREEN, HEXPAND_SCREEN, VEXPAND_SCREEN, PAGE_UP, SCROLL_UP, SCROLL_UP_TO_MARK, SCROLL_DOWN_TO_MARK, SET_MARK, INSERT_SELEC- TION, INSERT_CLIPBOARD, COPY_CLIPBOARD, RESET, COPY_MODE, "STRING", or "proto:STRING". IM_HOTKEY Switch conversion mode of m17n library and kdb input methods. (de- fault UNUSED) EXT_KBD Activate or deactivate kbd input method. (This feature was obso- leted 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). HSPLIT_SCREEN Open new pty in horizontally split screen (default Shift+F1). (If mlterm -v outputs "no-split", this shortcut key is unavailable.) VSPLIT_SCREEN Open new pty in vertically split screen (default Shift+F2). (If ml- term -v outputs "no-split", this shortcut key is unavailable.) NEXT_SCREEN Switch to a next unfocused screen (default Shift+F3). PREV_SCREEN Switch to a previous unfocused screen (default Shift+F4). CLOSE_SCREEN Close current screen (default Shift+F5). HEXPAND_SCREEN Expand current screen horizontally (default Shift+F6). (If mlterm -v outputs "no-split", this shortcut key is unavailable.) VEXPAND_SCREEN Expand current screen vertically (default Shift+F7). (If mlterm -v outputs "no-split", this shortcut key is unavailable.) PAGE_UP Start backscroll mode and scroll up one page (default Shift+Prior). SCROLL_UP Start backscroll mode and scroll up by one line (default Shift+Up). SCROLL_UP_TO_MARK Start backscroll mode and scroll up to the next marked line (default Control+Shift+Up). SCROLL_DOWN_TO_MARK Scroll down to the next marked line (default Control+Shift+Down). SET_MARK Set mark to the current line (default Control+Shift+m). INSERT_SELECTION Insert selection (default Shift+Insert). INSERT_CLIPBOARD Insert clipboard (default Shift+Control+v). COPY_CLIPBOARD Copy selected text to clipboard (default Shift+Control+c). RESET Reset terminal (default Pause). COPY_MODE Enter copy mode which enables you to select and copy region by key- board (default Control+Shift+Return). "STRING" The specified string is issued when the KEY key is pressed. Double quotation marks are required around the STRING. Note that you can- not 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 se- quence. 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. If you want to show issued STRING in the screen in pressing shortcut keys, prepend "(echo)" to STRING. For example, "proto:(echo)encoding=utf8" shows "Config: encoding=utf8". "exesel:STRING" The specified string is assumed to a command to be executed with se- lected strings as arguments. "%s" in a command string is replaced by selected strings. For example, "exesel:mlclient -e w3m" means exe- cuting "mlclient -e w3m [selected text]". "menu:STRING" The specified string is assumed to a configuration program to be ex- ecuted. For example, "menu:mlterm-menu" means executing mlterm- menu. 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 ml- term's behavior. (Since mlterm' can behave as a xterm/kterm to some ex- tent, TERM=kterm / TERM=xterm should give acceptable results.) However, sometimes you may not want to edit your terminfo and termcap. Your soft- ware 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 term- cap 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 (de- fault ^H). kh=sequence Specify sequence to be outputted when HOME key is pushed in applica- tion cursor key mode. (default \EOH). @7=sequence Specify sequence to be outputted when END key is pushed in applica- tion cursor key mode. (default \EOF). k1=sequence Specify sequence to be outputted when F1 key is pushed (default \EOP). k2=sequence Specify sequence to be outputted when F2 key is pushed (default \EOQ). k3=sequence Specify sequence to be outputted when F3 key is pushed (default \EOR). k4=sequence Specify sequence to be outputted when F4 key is pushed (default \EOS). k5=sequence Specify sequence to be outputted when F5 key is pushed (default \E[15~). 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.
