+================================================================================
-NAME
- iomenu – interactive selection menu
+*iomenu* is an interactive menu inspired from dmenu [1]: it reads lines from
+stdin display them to the screen [1], and filter them as the user type. When
+`Enter` is pressed, the selected line is printed to stdout.
-SYNOPSIS
- iomenu [-#] [-l lines] [-p prompt]
+This permits to build interactive menu with shell pipes. As an example, a poor
+man's music player could be done this way:
-DESCRIPTION
- iomenu is an interactive filtering and selection tool for the terminal.
+ $ find ~/music -name '*.flac' | iomenu | xargs mplayer
- It reads lines from standard input, and prompt for a selection. The
- selected line is printed to standard output.
+It will print all the FLAC files in `~/music` to iomenu which shows a fulscreen
+menu, and the selected file will be printed to xargs mplayer.
- -l lines If lines is 0 or if -l is not set, the items are
- displayed in an horizontal list. Otherwise, in a
- vertical list of at most lines lines.
+iomenu does not use ncurses but ansi escape sequences [2] instead so it does
+not have dependencies beyond a C compiler.
- -p prompt Set the prompt to display at the beginning of the input
- to prompt.
-
- -# If a line starts with #, iomenu will interprete it as a
- header, which always matches, and can not be printed.
-
-KEY BINDINGS
- An active selection is highlighted, and can be controlled with
- keybindings. As printable keys are entered, the lines are filtered to
- match each word from the input.

- Move selection to the previous/next item.
-
- PageUp, PageDown, Alt + v, Ctrl + v

- Print the selection to the standard output, and exit 0.
