DESCRIPTION

A collection of simple applications and utilities that operate under the Wm window manager.  Other Wm applications exist, see their respective manual pages for more information. 

­wm/about
Display system version and copyright information.

­wm/coffee
A whimsical plaything.

­wm/colors
Displays the Inferno palette. Clicking on a particular colour displays its RGB values.

­wm/date
Displays the current date and time in a window.

­wm/edit
A simple cut-and-paste text editor. Several menus provide the usual editing commands. Text selections are dragged out using mouse button-1. Mouse button-2 displays a pop-up menu of the Cut, Copy and Paste commands.

­wm/memory
Displays memory usage. Three usage bars are displayed, one for each of the Inferno memory pools: main, heap and image. The maximum permitted size of each pool is given (in megabytes) to the left of its usage bar. Each bar also sports a highwater mark. The usage data is re-read and displayed once every second.

­wm/rt
A Dis module inspector: it can show the Dis instructions, strings, types and other attributes of a module; it also allows the user to set some attributes stored in a module’s header.

­wm/stopwatch
A simple-minded stopwatch. Only useful for coarse-grained timings.

­wm/tetris
The ubiquitous and annoyingly addictive tile dropping game. The game keys are: ‘7’ move left; ‘8’ rotate (anti-clockwise); ‘9’ move right; ‘p’ pause; ‘space’ drop and ‘q’ quit.  Scores are stored in the file /lib/scores/tetris.  Score file updates are not interlocked − it’s only a game! 

­wm/unibrowse
A handy utility for browsing the unicode character set, finding out what particular characters look like in different fonts, finding out exactly which characters a font provides, and finding the name of a character that you have managed to grab into the snarf buffer.

­wm/view
Image viewer. Displays GIF, JPEG, Inferno BIT and X bitmap image files. The viewer creates a new window to display the contents of each file. If no arguments are given, the file browser panel wm-filename(1) is displayed to prompt the user to select an image file to view.

­wm/winctl
Window management tool. Displays a set of buttons that provide for: raising a window to the top or lowering it to the bottom of the screen window stack; moving a window to a new position; iconising a window; deleting a window.

Click on the button for the required action then click on the window to apply it to.  When moving a window, click and drag the target.  Deleting a window is error-prone. 

PLUMBING

­/lib/scores/tetris
