38to use ncurses and the panel, menu, and form libraries.

41
42ROADMAP AND PACKAGE OVERVIEW:
43
44You should be reading this file in a directory called: ncurses-d.d, where d.d
45is the current version number (see the dist.mk file in this directory for
46that). There should be a number of subdirectories, including `c++', `form',
47`man', `menu', `misc', `ncurses', `panel', `progs', `test', 'tack' and `Ada95'.
48(The 'tack' program may be distributed separately).
49
50A full build/install of this package typically installs several libraries, a
51handful of utilities, and a database hierarchy. Here is an inventory of the
52pieces:
53
54The libraries are:
55
56 libncurses.a (normal)
57 libncurses.so (shared)
58 libncurses_g.a (debug and trace code enabled)
59 libncurses_p.a (profiling enabled)
60
61 libpanel.a (normal)
62 libpanel.so (shared)
63 libpanel_g.a (debug and trace code enabled)
64
65 libmenu.a (normal)
66 libmenu.so (shared)
67 libmenu_g.a (debug enabled)
68
69 libform.a (normal)
70 libform.so (shared)
71 libform_g.a (debug enabled)
72
73If you configure using the --enable-widec option, a "w" is appended to the
74library names (e.g., libncursesw.a), and the resulting libraries support
75wide-characters, e.g., via a UTF-8 locale. The corresponding header files
76are compatible with the non-wide-character configuration; wide-character
77features are provided by ifdef's in the header files. The wide-character
78library interfaces are not binary-compatible with the non-wide-character
79version.
80
81The ncurses libraries implement the curses API. The panel, menu and forms
82libraries implement clones of the SVr4 panel, menu and forms APIs. The source
83code for these lives in the `ncurses', `panel', `menu', and `form' directories
84respectively.
85
86In the `c++' directory, you'll find code that defines an interface to the
87curses, forms, menus and panels library packaged as C++ classes, and a demo program in C++
88to test it. These class definition modules are not installed by the 'make
89install.libs' rule as libncurses++.
90
91In the `Ada95' directory, you'll find code and documentation for an
92Ada95 binding of the curses API, to be used with the GNAT compiler.
93This binding is built by a normal top-level `make' if configure detects
1d102085 94an usable version of GNAT (3.11 or above). It is not installed automatically.

95See the Ada95 directory for more build and installation instructions and
96for documentation of the binding.
97
98To do its job, the ncurses code needs your terminal type to be set in the
99environment variable TERM (normally set by your OS; under UNIX, getty(1)
100typically does this, but you can override it in your .profile); and, it needs a
101database of terminal descriptions in which to look up your terminal type's
102capabilities.
103
104In older (V7/BSD) versions of curses, the database was a flat text file,
105/etc/termcap; in newer (USG/USL) versions, the database is a hierarchy of
106fast-loading binary description blocks under /usr/lib/terminfo. These binary
107blocks are compiled from an improved editable text representation called
108`terminfo' format (documented in man/terminfo.5). The ncurses library can use
109either /etc/termcap or the compiled binary terminfo blocks, but prefers the
110second form.
111
112In the `misc' directory, there is a text file terminfo.src, in editable
113terminfo format, which can be used to generate the terminfo binaries (that's
114what make install.data does). If the package was built with the
115--enable-termcap option enabled, and the ncurses library cannot find a terminfo
116description for your terminal, it will fall back to the termcap file supplied
117with your system (which the ncurses package installation leaves strictly
118alone).
119
120The utilities are as follows:
121
122 tic -- terminfo source to binary compiler
123 infocmp -- terminfo binary to source decompiler/comparator
124 clear -- emits clear-screen for current terminal
125 tput -- shell-script access to terminal capabilities.
126 toe -- table of entries utility
127 tset -- terminal-initialization utility
128
129The first two (tic and infocmp) are used for manipulating terminfo
130descriptions; the next two (clear and tput) are for use in shell scripts. The
131last (tset) is provided for 4.4BSD compatibility. The source code for all of
132these lives in the `progs' directory.
133
134Detailed documentation for all libraries and utilities can be found in the
135`man' and `doc' directories. An HTML introduction to ncurses, panels, and
136menus programming lives in the `doc/html' directory. Manpages in HTML format
137are under `doc/html/man'.
138
139The `test' directory contains programs that can be used to verify or
140demonstrate the functions of the ncurses libraries. See test/README for
141descriptions of these programs. Notably, the `ncurses' utility is designed to
142help you systematically exercise the library functions.
