Please read Rob Pike's paper for a better and more complete description of the interface. History Wily emulates in the Unix and X Windows environment the Acme editor from Plan 9 . Also, a port of Acme would not be freely distributable. The screen is divided into columns, which are divided into windows. A window may represent a file, a directory, or the output from some program.
Text is displayed in a propotionally spaced font by default.
There is a built in function to toggle with a monospace font, but there are very few occasions when this is necessary or desirable. In most cases limiting a text editor to monospace fonts is blindly following the hardware limitations of the 1960s. All actions in Wily are through creating and interacting with text on the screen, using the three-button mouse and the keyboard. The address may be a line number, a character number, a regular expression, or two of these, separated by a comma. Wily's power derives in part from its general treatment of text.
