Importing usr.bin/msgc

Browse source 
Minix-specific changes were needed in msg_sys.def:

 * use minix_mmap()/minix_munmap() since mmap()/munmap() aren't
   defined on Minix.

 * use MAP_PRIVATE flag since MAP_SHARED isn't defined on Minix.

Tested with usr.bin/menuc/testm.

.Sh DESCRIPTION
This implements a curses based message display system.
A source file that lists messages with associated names is given to
.Nm
and produces both a .c and a .h file that implement the menu system.
The standard root name of the files is
.Pa msg_defs .
The
.Fl o Ar name
can be used to specify a different root name.
.Sh ENVIRONMENT
.Bl -tag -width MSGDEF
.It Ev MSGDEF
Can be set to point to a different set of
definition files for
.Nm msgc .
The current location defaults to
.Pa /usr/share/misc .
.El
.Sh FILES
.Bl -item
.It
.Pa /usr/share/misc/msg_sys.def
.El
.Sh SOURCE DESCRIPTION
The format is very simple.
Each message is started with the word
.Sq message
followed by the name of the message.
The body of the message is next and is started by a { and closed by a }.
The braces are not part of the message.
Everything, including newlines between the braces are part of the message.
.Sh MESSAGE FUNCTIONS
The defined messages are used through calls routines that manipulate
the messages.
You first need to set the
.Xr curses 3
environment up and then tell the message system which window to use
for displaying message by calling the function
.Fn msg_window .
.Pp
All variable argument lists in the functions are used as
are arguments to
.Xr sprintf 3 .
The messages may have
.Xr sprintf 3
conversions in them and the corresponding parameters should match.
Messages are identified by name using the notation
.Sq MSG_name
where
.Dq name
is the name in the message source file.
(The definitions are accessed by including the generated .h file into a
source file wanting to use the message routines.)
.Pp
The function
.Fn msg_string
just returns a pointer to the actual message string.
The functions
.Fn msg_clear ,
.Fn msg_standout
and
.Fn msg_standend
respectively clear the message window, set standout mode and clear standout
mode.
.Pp
The functions
.Fn msg_display
and
.Fn msg_display_add
cause a defined message to be displayed in the message window and does
the requested conversions before printing.
The difference is that
.Fn msg_display
clears the window before displaying the message.
These functions fill paragraphs for readability.
The
.Fn msg_table_add
function behaves like
.Fn msg_display_add
but does not fill text.
.Pp
The function
.Fn msg_printf
allows to display a raw message without going through the message catalog.
.Pp
The remaining functions deal with a prompt facility.
A prompt message is either taken from the message directory or from a
given string.
The message is processed with
.Xr sprintf 3
and then displayed.
If the parameter
.Ar def
is
.No non- Ns Dv NULL
and not a string of zero length, a default value is printed
in brackets.
The user is allowed to type in a response.
If the user types just the newline character, the default is returned
in the value.
The parameter
.Ar max_chars
is the length of the parameter
.Ar val ,
where the results are stored.
The parameters
.Ar def
and
.Ar val
may point to the same character array.
If the default is chosen, the character array is not changed.
The functions
.Fn msg_echo
and
.Fn msg_noecho
control whether the prompt routine echo or don't echo the input that
is typed by the user.
.Pp
.Fn msg_prompt_win
uses the specified curses window instead of the default one.
.Pp
.Fn msg_row
return the current row - i.e.: getcury(msg_win) + getbegy(msg_win).
