NAME

     dvtm-editor — make a text editor act as a filter

SYNOPSIS

     dvtm-editor ARGS...

DESCRIPTION

     The dvtm-editor is a file buffering utility used by the dvtm(1) terminal multiplexer to
     implement its copy mode. It reads the standard input and saves it to a temporary file, then
     opens an editor according to the ENVIRONMENT VARIABLES.

     If the invoked editor terminates with a non-zero exit status or the file modification time
     remains unchanged, dvtm-editor does not output anything.  Otherwise, it outputs the content
     of the modified temporary file to stdout.

     All command line arguments are forwarded verbatim.  dvtm(1) uses this to adjust the initial
     view port by passing +n, meaning the start of line n should be displayed.

ENVIRONMENT VARIABLES

     dvtm-editor will try to find the user editor by checking these variables in order:

     DVTM_EDITOR
             Permitting to invoke an editor specific to dvtm, or set particular flags.

     VISUAL, EDITOR
             Falling back to global defaults: VISUAL and EDITOR.

     If no editor is found, vi(1) is used.

FILES

     The temporary files are created according to the template: /tmp/dvtm-editor.XXXXXX.

     /dev/tty is opened to obtain a controlling tty which is used for the standard input/output
     streams of the invoked editor.

NOTES

     Using vis(1) as editor is particularly convenient because :wq! in visual mode will reduce
     the file to the currently active selection(s).
