jfbterm.conf - configuration file for jfbterm(1)
This manual page documents briefly the jfbterm.conf configuration file
that is used in jfbterm(1) command.
The format of an entry for this file is:
entryName : value
If ‘+’ is at beginning of the line, value is added to entryName as an
array. This means that one entryName can have multiple values.
A summary of configrations is included below.
term TERM environment variable’s value for a program that runs in
jfbterm(1). The default is jfbterm.
This assigns a font for each character set. A term "character
set" means a set of characters and is an element for
"encodings". In other words, an encoding consists from one or
more character sets. In jfbterm, most of character sets are
assumed to have ISO-2022-compliant structure, i.e., a character
set contains 94 characters, 96 characters, 94^N characters, or
96^N characters. iso10646.1 is the only exception.
The format of fontset value is:
You can see a list of available charsetNames by running "jfbterm
type specifies "pcf" or "alias". If type is "pcf", fontname is
a pathname of a font file. If type is "alias", fontname
specifies another charsetName, which means that the character
set of charsetName will use the same font to the character set
side specifies in which side (GL or GR) the font has glyphs for
the character set, in terms of ISO-2022. L means GL (0x20-0x7f)
and R means GR (0xa0-0xff). A unique specification, U, is used
only for iso10646.1.
For example, iso8859.1-1987 is a character set which contains 96
characters. The glyphs for iso8859.1-1987 characters are
available in GR side of *-iso8859-1 fonts.
This defines an encoding. An encoding is what you really use to
express texts and consists from one or more character sets. In
jfbterm, most of encodings are defined as ISO-2022’s initial
state and jfbterm can change character sets by using ISO-2022
escape sequences. However, non-ISO-2022-compliant encodings
such as Big5 and KOI8-R are also supported via iconv(3).
The format of encoding value is
If encoding value is "locale" (the first case), then
encodingName value is initialized by the current LC_CTYPE locale
("locale -k charmap") and falling into the second case.
If no ‘,’ is found in encoding value, it is recognized as
encodingName (the second case). If the encodingName matches one
of encoding.encodingName which is explained below, this
definition is used. Otherwise, if the encodingName matches one
of valid encoding names for iconv(1) or iconv_open(3), jfbterm
will work in UTF-8 mode internally. This means that the font
defined by fontset:iso10646.1 line will be used and iconv(3)
will be used to emulate the given encodingName. This behavior
is just as if there is a line:
encoding.encodingName : other,encodingName,iconv,UTF-8
This mechanism enables jfbterm to support various encodings
which are not ISO-2022-compliant.
If a ‘,’ is found in encoding value, it is recognized as the
third case. This format defines an encoding as an ISO-2022
initial state. GL and GR specifies a slot (one of G0, G1, G2,
or G3) which is invoked into GL (0x20-0x7F) and GR (0xA0-0xFF).
G0, G1, G2, and G3 specifies the character set which is
designated into the corresponding slot.
The default is "locale".
This defines an encoding of encodingName as an ISO-2022 initial
state, like the third case of encoding item which is explained
already. The format is like following:
The first case is just same as explained in the third case of
The second case means that the encoding is UTF-8. This is a
The third case defines an encoding as a conversion of an other
encoding. jfbterm will use the encoding of
internal-encodingName internally and will use iconv(3) for
Note that, in the third case, internal-encodingName must be a
valid encoding name which is defined in other
encoding.encodingName line (which has the first or second
format). Both of internal-encodingName and encodingName must be
valid encoding names for iconv(1) or iconv_open(3). Also, Both
encodingNames (one is a part of encoding.encodingName and the
another appears next to "other,") must be same.
Color gamma value. The default is 1.7.
