Elvis 1.4 TERMCAP Page 10-1
E10. TERMCAPF
Elvis uses fairly standard termcap fields for most things. I
invented the cursor shape names but other than that there should be
no surprises.
E10.1 Required numeric fieldsF
:co#: number of columns on the screen (characters per line)
:li#: number of lines on the screen
E10.2 Required string fieldsF
:ce=: clear to end-of-line
:cl=: home the cursor & clear the screen
:cm=: move the cursor to a given row/column
:up=: move the cursor up one line
E10.3 Boolean fieldsF
:am: auto margins - wrap when a char is written to the last column?
:pt: physical tabs?
E10.4 Optional string fieldsF
:al=: insert a blank row on the screen
:dl=: delete a row from the screen
:cd=: clear to end of display
:ei=: end insert mode
:ic=: insert a blank character
:im=: start insert mode
:dc=: delete a character
:sr=: scroll reverse (insert a row at the top of the screen)
:vb=: visible bell
:ti=: terminal initialization string, to start full-screen mode
:te=: terminal termination, to end full-screen mode
:ks=: enables the cursor keypad
:ke=: disables the cursor keypad
E10.5 Optional strings received from the keyboardF
:kd=: sequence sent by the <down arrow> key
:kl=: sequence sent by the <left arrow> key
:kr=: sequence sent by the <right arrow> key
:ku=: sequence sent by the <up arrow> key
:kP=: sequence sent by the <PgUp> key
:kN=: sequence sent by the <PgDn> key
:kh=: sequence sent by the <Home> key
:kH=: sequence sent by the <End> key
Elvis 1.4 TERMCAP Page 10-2
Originally, termcap didn't have any names for the <PgUp>,
<PgDn>, <Home>, and <End> keys. Although the capability names
shown in the table above are the most common, they are -1not-0
universal. SCO Xenix uses :PU=:PD=:HM=:EN=: for those keys. Also,
if the four arrow keys happen to be part of a 3x3 keypad, then the
five non-arrow keys may be named :K1=: through :K5=:, so an IBM PC
keyboard may be described using those names instead. Elvis can any
of these names.
E10.6 Optional fields that describe character attributesF
:so=: :se=: start/end standout mode (We don't care about :sg#:)
:us=: :ue=: start/end underlined mode
:md=: :me=: start/end boldface mode
:as=: :ae=: start/end alternate character set (italics)
:ug#: visible gap left by :us=:ue=:md=:me=:as=:ae=:
E10.7 Optional fields that affect the cursor's shapeF
The :cQ=: string is used by elvis immediately before exiting to
undo the effects of the other cursor shape strings. If :cQ=: is
not given, then all other cursor shape strings are ignored.
:cQ=: normal cursor
:cX=: cursor shape used for reading EX command -- steady underline
:cV=: cursor shape used for reading VI commands -- steady block
:cI=: cursor shape used during VI input mode -- blinking underline
:cR=: cursor shape used during VI replace mode -- blinking block
If the capabilities above aren't given, then Elvis will try to
use the following values instead.
:ve=: normal cursor, used as :cQ=:cX=:cI=:cR=:
:vs=: gaudy cursor, used as :cV=:
E10.8 An exampleF
Here's the termcap entry I use on my Minix-ST system. Some of
the fields in it have nothing to do with Elvis. Some can only work
on my system; I have modified my kernel's screen driver.
