DESCRIPTION

27       Objects in this class provide access to terminfo database entires.
28
29       This database provides information about a terminal, in three separate
30       sets of capabilities. Flag capabilities indicate the presence of a
31       particular ability, feature, or bug simply by their presence. Number
32       capabilities give the size, count or other numeric detail of some
33       feature of the terminal. String capabilities are usually control
34       strings that the terminal will recognise, or send.
35
36       Capabilities each have two names; a short name called the capname, and
37       a longer name called the varname. This class provides two sets of
38       methods, one that works on capnames, one that work on varnames.
39
40       This module optionally uses unibilium to access the terminfo(5)
41       database, if it is available at compile-time. If not, it will use
42       <term.h> and -lcurses. For more detail, see the "SEE ALSO" section
43       below.

CONSTRUCTOR

46   new
47          $ti = Term::Terminfo->new( $termtype )
48
49       Constructs a new "Term::Terminfo" object representing the given
50       termtype. If $termtype is not defined, $ENV{TERM} will be used instead.
51       If that variable is empty, "vt100" will be used.
52

METHODS

54   getflag
55   getnum
56   getstr
57          $bool = $ti->getflag( $capname )
58
59          $num = $ti->getnum( $capname )
60
61          $str = $ti->getstr( $capname )
62
63       Returns the value of the flag, number or string capability of the given
64       capname.
65
66   flag_by_varname
67   num_by_varname
68   str_by_varname
69          $bool = $ti->flag_by_varname( $varname )
70
71          $num = $ti->num_by_varname( $varname )
72
73          $str = $ti->str_by_varname( $varname )
74
75       Returns the value of the flag, number or string capability of the given
76       varname.
77
78   flag_capnames
79   num_capnames
80   str_capnames
81          @capnames = $ti->flag_capnames
82
83          @capnames = $ti->num_capnames
84
85          @capnames = $ti->str_capnames
86
87       Return lists of the capnames of the supported flags, numbers, and
88       strings
89
90   flag_varnames
91   num_varnames
92   str_varnames
93          @varnames = $ti->flag_varnames
94
95          @varnames = $ti->num_varnames
96
97          @varnames = $ti->str_varnames
98
99       Return lists of the varnames of the supported flags, numbers, and
100       strings

TODO

103       This distribution provides a small accessor interface onto terminfo. It
104       was originally created simply so I can get at the "bce" capability flag
105       of the current terminal, because screen unlike every other terminal
106       ever, doesn't do this. Grrr.
107
108       It probably also wants more accessors for things like "tparm" and
109       "tputs".  I may at some point consider them.
