NAME

vmh - visual front-end to MH

SYNOPSIS

vmh[-prompt string][-vmhproc program] [-novmhproc][switches for vmhproc][-help]

DESCRIPTION

vmh is a program which implements the server side ofthe MH window management protocoland uses curses (3) routines to maintain a split-screen interface toany program which implements the client side of the protocol.This latter program, called the vmhproc,is specified using the `-vmhproc program' switch.

The upshot of all this is that one can run msh on a display terminaland get a nice visual interface.To do this, for example, just add the line

mshproc: vmh

to your .mh_profile.(This takes advantage of the fact thatmsh is the default vmhproc for vmh.)

In order to facilitate things,if the `-novmhproc' switch is given,and vmh can't run on the user's terminal,the vmhproc is run directly without the window management protocol.

After initializing the protocol,vmh prompts the user for a command to be given to the client.Usually, this results in output being sent to one or more windows.If a output to a window would cause it to scroll,vmh prompts the user for instructions,roughly permitting the capabilities of less or more(e.g., the ability to scroll backwards and forwards):

SPACE      advance to the next windowfulRETURN  *  advance to the next liney       *  retreat to the previous lined       *  advance to the next ten linesu       *  retreat to the previous ten linesg       *  go to an arbitrary line           (preceed g with the line number)G       *  go to the end of the window           (if a line number is given, this acts like `g')CTRL-L     refresh the entire screenh          print a help messageq          abort the window

(A `*' indicates that a numeric prefix is meaningful for this command.)

Note that if a command resulted in more than one window's worth ofinformation being displayed,and you allow the command which is generating information for the window togracefully finish(i.e., you don't use the `q' command to abort information being sent to thewindow),then vmh will give you one last change to peruse the window.This is useful for scrolling back and forth.Just type `q' when you're done.

To abnormally terminate vmh (without core dump),use <QUIT> (usually CTRL-\).For instance,this does the ``right'' thing with bbc and msh.^$HOME/.mh_profile~^The user profile^Path:~^To determine the user's MH directorymsh(1)`-prompt (vmh) '`-vmhproc msh'NoneThe argument to the `-prompt' switch must be interpreted as a single tokenby the shell that invokes vmh.Therefore,one must usually place the argument to this switch inside double-quotes.

At present,there is no way to pass signals (e.g., interrupt, quit) to the client.However,generating QUIT when vmh is reading a command from the terminal issufficient to tell the client to go away quickly.

Acts strangely (loses peer or botches window management protocol with peer)on random occasions.
