wimenu - The wmii menu program


wimenu [-i] [-h <history file>] [-n <history count>] [-p <prompt>]

wimenu -v


wimenu is wmii's standard menu program. It's used extensively by wmii and related programs
to prompt the user for input. The standard configuration uses it to launch programs,
select views, and perform standard actions. It supports basic item completion and history


Normal use of wimenu shouldn't require any arguments other than the following. More
advanced options are documented below.

-h <history file>
Causes wimenu to read its command history from <history file> and to append its
result to that file if -n is given.

-i Causes matching of completion items to be performed in a case insensitive manner.

-n <count>
Write at most <count> items back to the history file. The file is never modified
unless this option is provided. Duplicates are filtered out within a 20 item
sliding window before this limit is imposed.

-p <prompt>
The string <prompt> will be show before the input field when the menu is opened.

-r <rows>
Display completion items as a vertical list, one per row, rather than a horizontal
list, side-by-side. A maximum of <rows> rows will be displayed.


-a The address at which to connect to wmii.

-K Prevents wimenu from initializing its default key bindings. WARNING: If you do
this, be sure to bind a key with the Accept or Reject action, or you will have no
way to exit wimenu.

-k <key file>
Key bindings will be read from <key file>. Bindings appear as:

<key> [action] [args]

where <key> is a key name, similar to the format used by wmii. For action and args,
please refer to the default bindings, provided in the source distribution under
cmd/menu/keys.txt, or use strings(1) on the wimenu executable (this level of
customization is reserved for the determined).

-s <screen>
Suggests that the menu open on Xinerama screen <screen>.

-S <command separator>

Causes each input item to be split at the first occurance of <command sep>. The
text to the left of the separator is displayed as a menu option, and the text to
the right is displayed when a selection is made.


wimenu's default key bindings are based largely on the movement keys of vi and the
standard UNIX shell input bindings.

Return, C-j, C-m
Accept the input, and select the first matching completion if the cursor is at the
end of the input.

S-Return, C-S-j, C-S-m
Accept the input literally.

Esc, C-[
Quit without returning any output, and exit with non-zero status.

A-p Paste the PRIMARY selection.

Left, C-b
Move backward one character.

Right, C-f
Move forward one character.

A-b Move backward one word.

A-f Move forward one word.

C-a Move to the beginning of the line.

C-e Move to the end of the line.

C-p, Up
Move backward through the input history.

C-n, Down
Move forward through the input history.

Backspace, C-h
Delete the previous character.

C-Backspace, C-w
Delete the previous word.

C-u Delete the previous portion of the line.

Tab, C-i¸ A-l
Select the next completion.

S-Tab, C-S-i, A-h
Select the previous completion.

PageUp, A-k
Select the previous completion page.

PageDown, A-j
Select the next completion page.

Home, A-g
Select the first completion page.

End, A-S-g
Select the last completion page.


Custom, multipart completion data may be proveded by an external application. When the
standard input is not a TTY, processing of a set of completions stops at every blank line.
After the first new line or EOF, wimenu displays the first set of menu items, and waits
for further input. The completion items may be replaced by writing out a new set, again
followed by a new line. Every set following the first must begin with a line containing a
single decimal number specifying where the new completion results are to be spliced into
the input. When an item is selected, text from this position to the position of the caret
is replaced.

-c Prints the contents of the input buffer each time the user inputs a character, as

<text before caret>\n<text after caret>\n

Let's assume that a script would like to provide a menu with completions first for a
command name, then for arguments to that command. Given three commands and argument sets,


1, 2, 3


4, 5, 6


7, 8, 9

the following script provides the appropriate completions:

#!/bin/sh \-f

rm fifo
mkfifo fifo

# Open wimenu with a fifo as its stdin
wimenu \-c <fifo | awk '
# Define the completion results
cmds = "foo\nbar\nbaz\n"
cmd["foo"] = "1\n2\n3\n"
cmd["bar"] = "4\n5\n6\n"
cmd["baz"] = "7\n8\n9\n"

# Print the first set of completions to wimenu’s fifo
fifo = "fifo"
print cmds >fifo; fflush(fifo)

{ print; fflush() }

# Push out a new set of completions
function update(str, opts) {
print length(str) >fifo # Print the length of the preceding string
print opts >fifo # and the options themself

# Ensure correct argument count with trailing spaces
/ $/ { $0 = $0 "#"; }

{ # Process the input and provide the completions
if (NF == 1)
update("", cmds) # The first arg, command choices
update($1 " ", cmd[$1]) # The second arg, command arguments
# Skip the trailing part of the command
getline rest
' | tail \-1

In theory, this facility can be used for myriad purposes, including hijacking the
programmable completion facilities of most shells. See also the provided examples[1].
