NEW ! Now with mouse !
NEW ! Now with speech !
Term::Clui offers a high-level user interface, with subroutines &choose
&ask &edit &view &confirm and &sorry. It works at a higher level than
widgets; it gives command-line applications a consistent "look and feel".
Its metaphor for the computer is a human-like conversation-partner,
and as each answer/response is completed it is summarised onto one line,
and remains on screen, so that the history of the dialogue gradually
accumulates on the screen and is available for review, or for cut/paste.
Also included is the file-selector module Term::Clui::FileSelect,
with its main subroutine &select_file. Term::Clui doesn't yet work
under Windows.
To install just:
perl Makefile.PL ; make ; make install
For up-to-date source, see http://search.cpan.org/~pjb
&edit and &view use the default EDITOR and PAGER from the user's
environment, except that if &view is called with a very short text
a builtin viewer is used, allowing the user to choose whether the
text remains on-screen or is cleared.
&confirm expects Y,y,N or n. &ask respects left and right arrows
and backspace, ctrl-B moves to the beginning, ctrl-E to the end,
and ctrl-D or ctrl-X clear the current string.
&choose maintains a DBM database of what the user chose last time in
response to the same question, and if it's still in the list this
time then &choose highlights it as the default. Thus &choose manages
its own defaults, and menus using Term::Clui autoconfigure themselves
to the user's preferences. When &choose is called in an array context,
it offers the user a multiple choice; mouse-button3 or the Spacebar
mark items in a multiple choice. If the choices won't fit on the
screen the user is asked for a substring clue.
The programmer can pass &ask a default string, as an optional second
argument. &select_file obeys options modelled after those of
Tk::FileDialog.pm and Tk::SimpleFileSelect.pm
Term::Clui is fast, very easy for both programmer and user, and has
few external dependencies. It doesn't use curses which is a whole-of
-screen interface; it uses a portable subset of vt100 sequences (up
left right normal reverse clrtoeol and mouse-reporting). It handles
window size changes, using Term::ReadKey or Term::Size if available;
if not, it tries `tput`.
For the user, Version 1.50 introduced a significant upgrade: mouse-
-handling. The user can now select an item in &choose using the mouse
and left-click, as well as by using the arrowkeys and return as before
(or q or ctrl-X to quit); button3 or the spacebar mark items in a
multiple choice. Since version 1.62, mouse-handling can be disabled
by setting CLUI_MOUSE=OFF; by default, it is on.
Since version 1.60, a speaking interface is provided for the visually
impaired user. It employs either eflite or espeak. Speech is turned
on if the CLUI_SPEAK environment variable is set to a non-empty string;
by default, it is off. If speakup is running, then it is silenced
while Term::Clui runs, and then restored. Because Term::Clui's
metaphor for the computer is a human-like conversation-partner, this
works very naturally, and the application needs no modification.
A calling-interface-compatible Python3-module is included.
