Win32 `Readline Console'
Author: Jan Wielemaker
E-mail: jan@swi.psy.uva.nl
Purpose
=======
The `readline console' provides a simple, but reasonable powerful
console window for running standard I/O based applications that may wish
to access Windows functions.
The console window is inspired by both the X11 xterm application and the
GNU readline library. The text is buffered to provide for window
resizing and scroll-back. When reading input by line, an Emacs like
editor is provided for editing the input line. Old input lines are
remembered and used by the history system.
Edit functions
==============
The following edit functions are provided:
Control-A Beginning of line
Control-B Character backward
Control-C Generate interrupt
Control-D Delete character forwards, or end-of-file
Control-E End of line
Control-F Character forwards
Control-I (TAB) Complete (filename, may be programmed)
Control-J (NL) Enter (make line available)
Control-K Delete to end-of-line
Control-M (RET) Enter (make line available)
Control-N Next line in history
Control-P Previous line in history
Control-T Toggle characters around caret
Control-U Empty line
Control-V Paste
Control-Z End-of-file
DEL Delete character forwards
BACKSPACE Delete character backwards
<-, -> Move caret in line, with SHIFT down, move
by word.
Up, down Move in history list
Mouse-bindings:
Left: Start selection, dragging extends the selection.
Double-click selects in `word-mode'. The
selection is placed on the Windows clipboard.
Middle: Paste the Windows clipboard (also Control-V).
Right: Extends the selection.
Compilation:
============
Includes a project file for MSVC 4.2. Please inspect the settings first.
plterm.dll is made from console.c, edit.c and history.c
Settings:
=========
Settings are kept in the Windows registry under the key
Software\<vendor>\<program>\Console
Where
<vendor> is SWI, unless compiled with a different setting for
RLC_VENDOR
<program> is the basename of the program without extension
(i.e. plwin for the program C:\Program
Files\pl\bin\plwin.exe).
Maintained values on this key are:
Name Type Description
================================================================
SaveLines int (200-100000) # lines saved for scrollback
Width int (20-300) # width in characters
Height int (5-100) # height in characters
X int (0-screen-width) # X-position of window
Y int (0-screen-height) # Y-position of window
FaceName str # Font info (settable using
FontFamily int # extension of Windows menu)
FontSize int
FontWeight int
FontCharSet int
