- WCED Command Line Editor and History
- ------------------------------------
- Copyright 1990 Stuart Russell
-
- Wced is a command line editor and history utility. It is capable of
- remembering the last 30 commands entered by the user. Only one
- instance of each command is remembered. It is also possible to remove
- from the history any unwanted commands. The main aim of Wced is to
- improve the command line editing of DOS but use as little memory as
- possible. When installed, wced uses approximately 10k of conventional
- memory.
-
- Usage:
- wced [-c] [commands]
-
- The c flag allows continuous movement through the history. Normally
- when either end of the history is reached it is not possible to move
- any further. However, with the c flag specified moving past the first
- command entered will result in the bell being sounded. The next press
- of the UP arrow will display the last command entered. A similar operation
- occurs when moving forward through the history.
-
- The semi-colon delimited commands specified on the command line when Wced is
- invoked will be placed into the history list before any commands are typed
- at the DOS prompt. This enables popular commands to be retrieved by using
- the UP arrow.
-
- The default editor and history keys are as follows :
-
- Left Arrow Move cursor left along command line
- Right Arrow Move cursor right along command line
- CTRL-Left Move cursor left to end of word
- CTRL-Right Move cursor right to end of word
- Home Move to beginning of command line
- End Move to end of command line
- Up Arrow Move backwards through history
- Down Arrow Move forwards through history
- ESC,ALT-d Delete entire command line
- Del Delete character under cursor on command line
- BS Delete character before cursor on command line
- F10 Quit and uninstall Wced
- ALT-r Remove entry on command line from history
- ALT-v Print version
- ALT-b Delete to beginning of command line
- ALT-e Delete to end of command line
- ALT-c Complete filename
- ALT-s Show possible filename completions
-
- Wced only operates in insert mode - there is no overtype mode.
-
- The history commands will attempt to complete the command on the
- command line. For example if the history contains 'ls','cd backup'
- and 'less nogood' and the user enters 'le' and presses the Up Arrow
- then the command will be completed as 'less nogood' (the quotes will
- not be printed). If Wced can not complete the command it will sound
- the bell.
-
- Version 1.5 of Wced has filename completion. This allows filenames to
- be completed at the press of a key. Wced will attempt to uniquely match
- the partial filename given. If this is not possible then no action is
- taken.
- Version 1.6 of Wced is able to show possible filename completions.

-
- The Wced program is accompanied by a program called Wkeys. This allows
- the editor and history keys to be reprogrammed to suite the user. Wkeys
- allows the use of the extended keys, ie F11, on an extended keyboard.
- The keys are defined in a data file an example of which is supplied.
-
- Usage:
- wkeys exe_filename data_filename
-
- If an error occurs the exe file will not be updated.
