.SH NAME

gridmenu \- grid window manager menu
|
||||
.SH SYNOPSIS
|
||||
.B gridmenu
|
||||
.RB [ \-v ]
|
||||
.RB [ \-t
|
||||
.IR title ]
|
||||
.SH DESCRIPTION
|
||||
.SS Overview
|
||||
.B gridmenu
|
||||
is a generic, highly customizable, and efficient menu for the X Window System,
|
||||
originally designed for
|
||||
.BR grid (1).
|
||||
It supports arbitrary, user defined menu contents.
|
||||
.SS Options
|
||||
.TP
|
||||
.B \-v
|
||||
prints version information to stdout, then exits.
|
||||
.TP
|
||||
.BI \-t " title"
|
||||
displays
|
||||
.I title
|
||||
above the menu.
|
||||
.SS Usage
|
||||
.B gridmenu
|
||||
reads a list of newline-separated items from stdin and creates a menu.
|
||||
When the user selects an item or enters any text and presses Enter, his choice
|
||||
is printed to stdout and
|
||||
.B gridmenu
|
||||
terminates.
|
||||
.SS Keyboard Control
|
||||
.B gridmenu
|
||||
is completely controlled by the keyboard. The following keys are recognized:
|
||||
.TP 2
|
||||
Any printable character
|
||||
appends the character to the text in the input field. This works as a filter:
|
||||
only items containing this text will be displayed.
|
||||
.TP 2
|
||||
Left/Right (Control-p/Control-n)
|
||||
select the previous/next item.
|
||||
.TP 2
|
||||
Tab (Control-i)
|
||||
copy the selected item to the input field.
|
||||
.TP 2
|
||||
Enter (Control-j)
|
||||
confirm selection and quit (print the selected item to stdout).
|
||||
.TP 2
|
||||
Shift-Enter (Shift-Control-j)
|
||||
confirm selection and quit (print the text in the input field to stdout).
|
||||
.TP 2
|
||||
Escape (Control-[)
|
||||
quit without selecting an item.
|
||||
.TP 2
|
||||
Backspace (Control-h)
|
||||
remove enough characters from the input field to change its filtering effect.
|
||||
.TP 2
|
||||
Control-u
|
||||
remove all characters from the input field.
|
||||
.SS Exit codes
|
||||
.B gridmenu
|
||||
returns
|
||||
.B 0
|
||||
if Enter is pressed on termination,
|
||||
.B 1
|
||||
if Escape is pressed.
|
||||
.SH ENVIRONMENT
|
||||
.TP
|
||||
GRID_FONT
|
||||
The X11 font used to display each item in the menu.
|
||||
.br
|
||||
Default: fixed
|
||||
.TP
|
||||
GRID_NORMCOLORS
|
||||
The foreground, background, and border colors of a label. Syntactically, three blank-separated color values of the form #RRGGBB are expected.
|
||||
.br
|
||||
Default: #222222 #eeeeee #666666
|
||||
.TP
|
||||
GRID_SELCOLORS
|
||||
Like GRID_NORMCOLORS, but for the selected label.
|
||||
.br
|
||||
Default: #ffffff #335577 #447799
