.Sh NAME
.Nm terminfo
.Nd terminal capability definition
.Sh DESCRIPTION
.Nm
describes the capabilities of terminals, used by programs such as
.Xr vi 1 ,
.Xr rogue 6
and libraries such as
.Xr curses 3 .
The
.Nm
source described here needs to be compiled with
.Xr tic 1
to be of any use.
.Pp
Entries in
.Nm
consist of a number of comma separated fields.
White space after each comma is ignored.
Embedded commas must be escaped by using a backslash.
Lines beginning with
.Sq #
in the first column are treated as comments.
Blank lines are ignored.
.Pp
The header line must begin in column one and end with a comma.
Inside the header line are terminal name and aliases,
separated by vertical bars, the last one being the long
description of the terminal.
.Pp
Capability lines then follow, starting on column two and ending with a comma.
Each capability is listed by its name, followed by its value if applicable.
Booleans have no values, numeric values are prefixed by
.Sq #
and strings are prefixed by
.Sq = .
Numbers can range from 0 to 32767 and string values can be up to 1000
characters long.
This implementation supports strings upto 32767 characters long, including the
.Dv NUL
terminator.
.Pp
Some escapes are available for strings - both
.Sy \eE
and
.Sy \ee
map to the
.Dv ESC
character,
.Sy ^X
maps to a control-X for any appropriate X, and the sequences
.Sy \en ,
.Sy \er ,
.Sy \et ,
.Sy \eb
and
.Sy \ef
map to linefeed, return, tab, backspace, and formfeed respectively.
Any character can be escaped in octal, such as
.Sy \e072 .
If you need to encode a
.Dv NUL
character, it should be escaped as
.Sy \e200 .
.Pp
A delay in milliseconds may appear anywhere in a string capability,
prefixed with a dollar sign and enclosed by angled brackets, such as
.Sy $\*[Lt]5\*[Gt] .
.Ss String Parameters
String capabilities sometimes require parameters.
Normally this just involves replacing the parameter with a supplied
variable; however, there are cases where the variable needs to be manipulated
or used in conditional expressions.
A stack is also provided for simple pop and push operations.
.Pp
The below % encodings have the following meanings:
.Bl -tag -width %P[a-z]
.It Sy %%
outputs %
.It Sy %[[:]flags][width[.precision]][doxXs]
flags are
.Dq [-+#] .
Prefix with
.Sq \&:
to avoid interpreting
.Dq %-
as an operator.
.It Sy %c
pop a parameter and print the character representation of it.
.It Sy %s
pop a parameter and print the string representation of it.
.It Sy %p[1-9]
push the parameter [1-9].
.It Sy %P[a-z]
pop a parameter and push it to dynamic variable [a-z].
.It Sy %g[a-z]
push the dynamic variable [a-z].
.It Sy %P[A-Z]
pop a parameter and push it to static variable [a-z].
.It Sy %g[A-Z]
push the dynamic variable [A-Z].
.Pp
Static variables persist over
.Fn tparm
whereas dynamic variables do not.
.It Sy %'c'
char constant c.
.It Sy %{nn}
integer constant nn.
.It Sy %l
push the string length of the previously popped parameter.
.It Sy %+ Sy %- Sy %* Sy %/ Sy %m
arithmetic: pop two parameters and push the result.
.It Sy %& Sy %| Sy %^
bit operations: pop two parameters and push the result.
.It Sy %! Sy %~
unary operations: pop two parameters and push the result.
.It Sy %i
add 1 to parameters 1 and 2.
.It Sy %? Va expr Sy %t Ic then Sy %e Ic else Sy %;
If expr equates to zero then control passes to the optional else part.

.Ss Fetching Compiled Descriptions
This implementation uses hashed databases managed by
.Xr cdb 5
instead of directories.
To maintain compatability with other implementations,
.Pa .cdb
is appended to each file checked.
.Pp
If the environment variable
.Ev TERMINFO
is available, does not begin with
.Pq Sq / ,
can be compiled with the above rules and whose name matches
.Ev TERM
then it is used.
.Pp
If the environment variable
.Ev TERMCAP
is available and does not begin with a slash
.Pq Sq /
then it will be translated into
terminfo and compiled as above.
If its name matches
.Ev TERM
then it is used.
.Pp
If the environment variable
.Ev TERMINFO
is available and begins with a slash
.Pq Sq /
then only this file is searched.
Otherwise
.Nm
will first look for
.Pa $HOME/.terminfo ,
followed by
.Pa /usr/share/misc/terminfo
unless
.Ev TERMINFO_DIRS
is available.
If a matching description is not found then a small embedded database is
searched, which currently holds descriptions for ansi, dumb, vt100, vt220,
wsvt25, and xterm.
.Sh FILES
.Bl -tag -width /usr/share/misc/terminfo.cdb -compact

Database of terminal descriptions for personal use.
.It Pa /usr/share/misc/terminfo
File containing terminal descriptions.
.It Pa /usr/share/misc/terminfo.cdb
