NAME
dvtm - dynamic virtual terminal manager

SYNOPSIS
dvtm [-v] [-M] [-m modifier] [-d delay] [-h lines] [-t title] [-s status-fifo] [-c cmd-fifo] [command ...]

DESCRIPTION
dvtm is a dynamic tiling window manager for the console. As a console window manager it tries to make it easy to work with multiple console based applications.

-v  Print version information to standard output and exit.

-M  Toggle default mouse grabbing upon startup. Use this to allow normal mouse operation under X.

-m modifier
    Set command modifier at runtime.

-d delay
    Set the delay ncurses waits before deciding if a character that might be part of an escape sequence is actually part of an escape sequence.

-h lines
    Set the scrollback history buffer size at runtime.

-t title
    Set a static terminal title and don't change it to the one of the currently focused window.

    Open or create the named pipe cmd-fifo and look for commands to execute which were defined in config.h.

command ...
    Execute command(s), each in a separate window.

  Mouse commands

Copy and Paste
    By default dvtm captures mouse events to provide the actions listed below. Unfortunately this interferes with the standard X copy and paste mechanism. To work around this you need to hold down Shift while selecting or pasting text. Alternatively you can disable mouse support at compile time, start dvtm with the -M flag or toggle mouse support during runtime with Mod-M.

Button1 click
    Focus window.

Button1 double click
    Focus window and toggle maximization.

Button2 click
    Zoom/cycle current window to/from master area.

Button3 click
    Toggle minimization of current window.

  Copy mode
Copy mode gives easy access to past output by piping it to an editor. What ever the editor prints to stdout upon exiting will be stored in an internal register and can be pasted into other clients (via Mod-p )

ENVIRONMENT VARIABLES

DVTM
    Each process spawned by dvtm will have this variable set to the dvtm version it is running under.

DVTM_WINDOW_ID
    Each process also has access to its constant and unique window id.

DVTM_CMD_FIFO
    If the -c command line argument was specified upon dvtm startup, this variable will be set to the file name of the named pipe. Thus allowing the process to send commands back to dvtm.

DVTM_TERM
    By default dvtm uses its own terminfo file and therefore sets TERM=dvtm within the client windows. This can be overridden by setting the DVTM_TERM environment variable to a valid terminal name before launching dvtm.

DVTM_EDITOR
    When entering the copymode dvtm pipes the whole scroll back buffer to DVTM_EDITOR which is launched with - (indicating to read from stdin) as its only argument. If DVTM_EDITOR is not set EDITOR is checked, if this is also not set the default value specified in config.h is used instead.

EXAMPLE
See the dvtm-status script as an example of how to display text in the status bar.

CUSTOMIZATION
dvtm is customized by creating a custom config.h and (re)compiling the source code. This keeps it fast, secure and simple.
