.SH NAME
mlterm \- Multi Lingual TERMinal emulator on X
.SH SYNOPSIS
.B mlterm
.RB [\fIoptions\fP]
.\" ********************************************************************
.SH DESCRIPTION
\fBmlterm\fP 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 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.
.PP
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_(ASSAMESE|BENGALI|GUJARATI|
HINDI|KANNADA|MALAYALAM|ORIYA|PUNJABI|TAMIL|TELUGU), 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 \fBlocale\fR(7) for detail) \fBmlterm\fR will automatically select
proper encoding.
.PP
.\" ********************************************************************
.SH OPTIONS
Note that \fIbool\fR is to be substituted by \fBtrue\fR or \fBfalse\fR.
.TP
\fB\-A\fR, \fB\-\-aa\fR(=\fIbool\fR)
Use anti-aliased fonts. This option works only with Xft or cairo for now.
The default is \fBtrue\fR.
.TP
\fB\-B\fR, \fB\-\-sbbg\fR=\fIcolor\fR
Specify a background color of a scrollbar.
A valid value for \fIcolor\fR is a color name or a RGB value.
The color name should be defined in rgb.txt or "\fBcolor\fR" configuration file.
The RGB value's format should be "#RRGGBB", "#RRGGBBAA", "rgb:RR/GG/BB" or "rgba:RR/GG/BB/AA".
.TP
\fB\-C\fR, \fB\-\-ctl\fR(=\fIbool\fR)
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 \fBtrue\fR.
.TP
\fB\-E\fR, \fB\-\-km\fR=\fIencoding\fR
Specify encoding.
Valid encodings are listed in \fBDESCRIPTION\fR section
above in this man page.
\fBAUTO\fR makes mlterm determine the according according to
the current locale (default \fBAUTO\fR).
.TP
\fB\-F\fR, \fB\-\-sbfg\fR=\fIcolor\fR
Specify a foreground color of a scrollbar.
See \fB\-\-sbbg\fR option for valid values.
.TP
\fB\-G\fR, \fB\-\-vertical=\fImode\fR
Specify vertical writing mode.
\fBcjk\fR for RTL vertical writing and \fBmongol\fR for LTR one.
The default is \fBnone\fR which means horizontal writing mode.
.TP
\fB\-H\fR, \fB\-\-bright=\fIvalue\fR
Brightness of background images in percent.
See \fB\-p\fR option for details of background images.
The default is \fB100\fR (keep original).
.TP
\fB\-I\fR, \fB\-\-icon\fR=\fIname\fR
Specify a name to be used when a mlterm window is iconified.
The default is "\fBmlterm\fR".
.TP
\fB\-J\fR, \fB\-\-dyncomb\fR(=\fIbool\fR)
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 \fB\-Z\fR/\fB\-\-multicol\fR option for handling of fullwidth characters).
Thus, this mode enables you to use combining characters with
software which does not support combining characters.
The default is \fBfalse\fR.
.TP
\fB\-K\fR, \fB\-\-metakey\fR=\fIvalue\fR
Specify a key to be interpreted as a META key.
Valid \fIvalue\fRs are: \fBalt\fR, \fBmeta\fR, \fBhyper\fR,
\fBsuper\fR, \fBmod1\fR, \fBmod2\fR, \fBmod3\fR, \fBmod4\fR,
and \fBnone\fR.   The default is \fBnone\fR.

See \fB\-k\fR option also.
.TP
\fB\-L\fR, \fB\-\-ls\fR(=\fIbool\fR)

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 \fBmlterm\fR 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 \fBmlterm\fR 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 \fBtrue\fR.

.\" ********************************************************************
.SH 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.
.PP
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,
\fBmlterm\fR is designed to be able to receive characters from various
encodings as much as possible.
.PP
There are two internationalized types of selection.  One is
\fBCOMPOUND_TEXT\fR is the another is \fBUTF8_STRING\fR.
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.
.PP
Though the receiver of copy-and-paste can request the preferable
type of selection, the sender may not support the requested type.
Thus \fBmlterm\fR has to be able to process both of COMPOUND_TEXT
and UTF8_STRING.
.PP
On the other hand, encodings supported by \fBmlterm\fR (see
\fBDESCRIPTION\fR section for detail) are classified into four
categories;
.TP
(a) Unicode itself
UTF-8.
.TP
(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.
.TP
(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.
.TP
(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.
.PP
Now the behavior of \fBmlterm\fR can be explained.
.PP

-------------------------------------------------------
.fi
.PP
*1 Characters from unsupported character sets (i.e., characters
which cannot be expressed in the \fBmlterm\fR 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 \fBmlterm\fR encoding
(i.e., characters which share the same codepoint in Unicode),
you can use \fB\-U\fR (or \fB\-\-viaucs\fR) option.  Otherwise,
these characters are pasted into \fBmlterm\fR using ISO-2022
escape sequence (when \fBmlterm\fR encoding is category b).
Note such ISO-2022 escape sequences are illegal in the current
\fBmlterm\fR encoding and the application software will need
special feature to treat them properly, though it is displayed
well in \fBmlterm\fR.  When \fBmlterm\fR encoding is category c,
such characters are simply ignored (when \fB\-U\fR option is
not enabled).
.PP
*2 Characters which cannot be converted into \fBmlterm\fR encoding
are simply ignored.
.PP
*3 Characters from unsupported character sets will be pasted
into \fBmlterm\fR using ISO-2022 escape sequence.

\fB"proto:\fISTRING\fB"\fR
The specified string is assumed to \fBmlterm\fR's original control
sequence. A list of sequences should be found in \fBdoc/en/PROTOCOL\fR.
For example, \fB"proto:encoding=utf8"\fR
means changing the current character encoding to UTF-8.
.TP
\fB"exesel:\fISTRING\fB"\fR
The specified string is assumed to a command to be executed with selected
strings as arguments.
For example, \fB"exesel:mlclient -e w3m"\fR means executing
"mlclient -e w3m [selected text]".

.SS Terminal Behavior Configuration File
This configuration file determines the behaviors of \fBmlterm\fR
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 \fBTERM\fR variable (i.e., proper terminfo/termcap
definition) which meets \fBmlterm\fR's behavior.
(Since \fBmlterm\fR' can behave as a xterm/kterm to some extent,
\fBTERM=kterm\fR / \fBTERM=xterm\fR 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 \fBmlterm\fR
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.
.PP
You can define the behaviors of \fBmlterm\fR for each value
of \fBTERM\fR variable, so that you don't need to edit \fBtermcap\fR
file each time you login into other systems and use different
value of \fBTERM\fR variable by \fB\-y\fR option.  You can also specify
the default behavior when \fBTERM\fR variable is different from all
of specified TERM names in the \fBtermcap\fR file.
.PP
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.
.PP
Followings are available keys for each TERM value.

.TP
\fBk4=\fIsequence\fR
Specify sequence to be outputted when F4 key is pushed
(default \fB\\EOS\fR).
.TP
\fBk5=\fIsequence\fR
Specify sequence to be outputted when F5 key is pushed
(default \fB\\E[15~\fR).
.TP
\fBut\fR
Specify the way how the screen is erased by control codes.
If \fBut\fR is written in the \fBtermcap\fR file, charcells
are painted by the current background color when erased;
otherwise the charcells are painted by the initial background
color.  Default is non-\fBut\fR behavior.
.PP
The following special characters can be used to specify \fIsequence\fR
in keys of \fBkD\fR/\fBkb\fR/\fBkh\fR/\fB@7\fR.
.TP
\fB\\E\fR
ESC code (0x1b).
.TP
\fB^?\fR
DEL code (0x7f).
.TP
\fB^A\fR, \fB^B\fR,...
Corresponding control code (0x01 \- 0x1a).
