WIMENU wmii-@VERSION@ Oct, 2009 %!includeconf: header.t2t = NAME = wimenu - The wmii menu program = SYNOPSIS = wimenu [-i] [-h ] [-n ] [-p ] + wimenu -v = DESCRIPTION = `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 searching. = BASIC ARGUMENTS = Normal use of `wimenu` shouldn't require any arguments other than the following. More advanced options are documented below. : -h Causes `wimenu` to read its command history from 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 Write at most 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 The string will be show before the input field when the menu is opened. : -r Display completion items as a vertical list, one per row, rather than a horizontal list, side-by-side. A maximum of rows will be displayed. : = ADVANCED ARGUMENTS = : -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 bindings will be read from . Bindings appear as: [action] [args] where 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 Suggests that the menu open on Xinerama screen . : -S Causes each input item to be split at the first occurance of . 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. = KEY BINDINGS = `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 begining 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 COMPLETION = 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. == ARGUMENTS == : -c Prints the contents of the input buffer each time the user inputs a character, as such: \n\n : == EXAMPLE == 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, : foo 1, 2, 3 : bar 4, 5, 6 : baz 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; 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 fflush(fifo) } # 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 else 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.
