16 "Curses" is the interface between Perl and your system's curses(3)
17 library. For descriptions on the usage of a given function, variable,
18 or constant, consult your system's documentation, as such information
19 invariably varies (:-) between different curses(3) libraries and
20 operating systems. This document describes the interface itself, and
21 assumes that you already know how your system's curses(3) library
22 works.
23 Unified Functions
25 Many curses(3) functions have variants starting with the prefixes w-,
26 mv-, and/or wmv-. These variants differ only in the explicit addition
27 of a window, or by the addition of two coordinates that are used to
28 move the cursor first. For example, "addch()" has three other
29 variants: "waddch()", "mvaddch()", and "mvwaddch()". The variants
30 aren't very interesting; in fact, we could roll all of the variants
31 into original function by allowing a variable number of arguments and
32 analyzing the argument list for which variant the user wanted to call.
33 Unfortunately, curses(3) predates varargs(3), so in C we were stuck
35 with all the variants. However, "Curses" is a Perl interface, so we
36 are free to "unify" these variants into one function. The section
37 "Available Functions" below lists all curses(3) functions "Curses"
38 makes available as Perl equivalents, along with a column listing if it
39 is unified. If so, it takes a varying number of arguments as follows:
40 "function( [win], [y, x], args );"
42 win is an optional window argument, defaulting to "stdscr" if not
44 specified.
45 y, x is an optional coordinate pair used to move the cursor,
47 defaulting to no move if not specified.
48 args are the required arguments of the function. These are the
50 arguments you would specify if you were just calling the base
51 function and not any of the variants.
52 This makes the variants obsolete, since their functionality has been
54 merged into a single function, so "Curses" does not define them by
55 default. You can still get them if you want, by setting the variable
56 $Curses::OldCurses to a non-zero value before using the "Curses"
57 package. See "Perl 4.X "cursperl" Compatibility" for an example of
58 this.
59 Wide-Character-Aware Functions
61 The following are the preferred functions for working with strings,
62 though they don't follow the normal unified function naming convention
63 (based on the names in the Curses library) described above. Despite
64 the naming, each corresponds to a Curses library function. For
65 example, a "getchar" call performs a Curses library function in the
66 "getch" family.
67 In addition to these functions, The "Curses" module contains
69 corresponding functions with the conventional naming (e.g. "getch");
70 the duplication is for historical reasons. The preferred functions
71 were new in Curses 1.29 (April 2014). They use the wide character
72 functions in the Curses library if available (falling back to using the
73 traditional non-wide-character versions). They also have a more Perl-
74 like interface, taking care of some gory details under the hood about
75 which a Perl programmer shouldn't have to worry.
76 The reason for two sets of string-handling functions is historical.
78 The original Curses Perl module predates Curses libraries that
79 understand multiple byte character encodings. Moreover, the module was
80 designed to have a Perl interface that closely resembles the C
81 interface syntactically and directly passes the internal byte
82 representation of Perl strings to C code. This was probably fine
83 before Perl got Unicode function, but today, Perl stores strings
84 internally in either Latin-1 or Unicode UTF-8 and the original module
85 was not sensitive to which encoding was used.
86 While most of the problems could be worked around in Perl code using
88 the traditional interface, it's hard to get right and you need a wide-
89 character-aware curses library (e.g. ncursesw) anyway to make it work
90 properly. Because existing consumers of the Curses module may be
91 relying on the traditional behavior, Curses module designers couldn't
92 simply modify the existing functions to understand wide characters and
93 convert from and to Perl strings.
94 None of these functions exist if Perl is older than 5.6.
96 "getchar"
98 This calls "wget_wch()". It returns a character -- more precisely, a
100 one-character (not necessarily one-byte!) string holding the character
101 -- for a normal key and a two-element list "(undef, key-number)" for a
102 function key. It returns "undef" on error.
103 If you don't expect function keys (i.e. with "keypad(0))", you can
105 simply do
106 my $ch = getchar;
108 die "getchar failed" unless defined $ch;
109 If you do expect function keys (i.e. with keypad(1)), you can still
111 assign the result to a scalar variable as above. Because of of the way
112 the comma operator works, that variable will receive either "undef" or
113 the string or the number, and you can decode it yourself.
114 my $ch = getchar;
116 die "getchar failed" unless defined $ch;
117 if (<$ch looks like a number >= 0x100>) {
118 <handle function key>
119 } else {
120 <handle normal key>
121 }
122 or do
124 my ($ch, $key) = getchar;
126 if (defined $key) {
127 <handle function key $key>
128 } else if (defined $ch) {
129 <handle normal key $ch>
130 } else {
131 die "getchar failed";
132 }
133 If "wget_wch()" is not available (i.e. The Curses library does not
135 understand wide characters), this calls "wgetch()", but returns the
136 values described above nonetheless. This can be a problem because with
137 a multibyte character encoding like UTF-8, you will receive two one-
138 character strings for a two-byte-character (e.g. "Ã" and "¤" for
139 "ä"). If you append these characters to a Perl string, that string
140 may internally contain a valid UTF-8 encoding of a character, but Perl
141 will not interpret it that way. Perl may even try to convert what it
142 believes to be two characters to UTF-8, giving you four bytes.
143 "getstring"
145 This calls "wgetn_wstr" and returns a string or "undef". It cannot
147 return a function key value; the Curses library will itself interpret
148 KEY_LEFT and KEY_BACKSPACE.
149 If "wgett_wstr()" is unavailable, this calls "wgetstr()".
151 In both cases, the function allocates a buffer of fixed size to hold
153 the result of the Curses library call.
154 my $s = getstring();
156 die "getstring failed" unless defined $s;
157 "addstring"/"insstring"
159 This adds/inserts the Perl string passed as an argument to the Curses
161 window using "waddnwstr()"/"wins_nwstr()" or, if unavailable,
162 "waddnstr()"/"winsnstr()". It returns a true value on success, false
163 on failure.
164 addstring("Hällö, Wörld") || die "addstring failed";
166 "instring"
168 This returns a Perl string (or "undef" on failure) holding the
170 characters from the current cursor position up to the end of the line.
171 It uses "winnwstr()" if available, and otherwise "innstr()".
172 my $s = instring();
174 die "instring failed" unless defined $s;
175 "ungetchar"
177 This pushes one character (passed as a one-character Perl string) back
179 to the input queue. It uses "unget_wch()" or "ungetch()". It returns a
180 true value on success, false on failure. It cannot push back a
181 function key; the Curses library provides no way to push back function
182 keys, only characters.
183 ungetchar("X") || die "ungetchar failed";
185 The "Curses" module provides no interface to the complex-character
187 routines ("wadd_wch()", "wadd_wchnstr()", "wecho_wchar()", "win_wch()",
188 "win_wchnstr()", "wins_wch()") because there is no sensible way of
189 converting from Perl to a C "cchar_t" or back.
190 Objects
192 Objects work. Example:
193 $win = new Curses;
195 $win->addstr(10, 10, 'foo');
196 $win->refresh;
197 ...
198 Any function that has been marked as unified (see "Available Functions"
200 below and "Unified Functions" above) can be called as a method for a
201 Curses object.
202 Do not use "initscr()" if using objects, as the first call to get a
204 "new Curses" will do it for you.
205 Security Concerns
207 It has always been the case with the curses functions, but please note
208 that the following functions:
209 getstr() (and optional wgetstr(), mvgetstr(), and mvwgetstr())
211 inchstr() (and optional winchstr(), mvinchstr(), and mvwinchstr())
212 instr() (and optional winstr(), mvinstr(), and mvwinstr())
213 are subject to buffer overflow attack. This is because you pass in the
215 buffer to be filled in, which has to be of finite length, but there is
216 no way to stop a bad guy from typing.
217 In order to avoid this problem, use the alternate functions:
219 getnstr()
221 inchnstr()
222 innstr()
223 which take an extra "size of buffer" argument or the wide-character-
225 aware getstring() and instring() versions.
226
228 Perl 4.X "cursperl" Compatibility
229 "Curses" was written to take advantage of features of Perl 5 and later.
230 The author thought it was better to provide an improved curses
231 programming environment than to be 100% compatible. However, many old
232 "curseperl" applications will probably still work by starting the
233 script with:
234 BEGIN { $Curses::OldCurses = 1; }
236 use Curses;
237 Any old application that still does not work should print an
239 understandable error message explaining the problem.
240 Some functions and variables are not available through "Curses", even
242 with the "BEGIN" line. They are listed under "Curses items not
243 available through Perl Curses".
244 The variables $stdscr and $curscr are also available as functions
246 "stdscr" and "curscr". This is because of a Perl bug. See the
247 LIMITATIONS section for details.
248 Incompatibilities with previous versions of "Curses"
250 In previous versions of this software, some Perl functions took a
251 different set of parameters than their C counterparts. This is not
252 true in the current version. You should now use "getstr($str)" and
253 "getyx($y, $x)" instead of "$str = getstr()" and "($y, $x) = getyx()".
254
256 · Curses function '%s' called with too %s arguments at ...
257 You have called a "Curses" function with a wrong number of

267 This probably means that you didn't give the right arguments to a
269 unified function. See the DESCRIPTION section on "Unified
270 Functions" for more information.

297
299 If you use the variables $stdscr and $curscr instead of their
300 functional counterparts ("stdscr" and "curscr"), you might run into a
301 bug in Perl where the "magic" isn't called early enough. This is
302 manifested by the "Curses" package telling you $stdscr isn't a window.
303 One workaround is to put a line like "$stdscr = $stdscr" near the front
304 of your program.
