NAME
xwpe, xwe, wpe, we - X-Window Programming Environment
SYNOPSIS
xwpe [ options ] file ...
xwe [ options ] file ...
wpe [ options ] file ...
we [ options ] file ...
DESCRIPTION
Xwpe can be used with or without the programming interface. It has its
own X interface but can be used also on a character terminal. xwpe
fires up the X interface together with the programming interface. xwe
is the X version but without the special features of the programming
interface. In connection with a simple character terminal you can use
wpe to program and we as editor.
Xwpe is a X-window programming environment designed for use on UNIX-
systems. It is similar to the ’Borland C++ or Turbo Pascal’
environments. The differences between the programming environments from
Borland and xwpe is that many compilers, linkers, and debuggers can be
used in xwpe. Menus and commands are accessible via both the keyboard
and mouse.
Errors that occur while compiling and linking a program can be examined
in the sources. The cursor will jump to the corresponding line in the
source-file. Programs using more than one source-file can be managed
with the so called "project-option" (see also project-file). The
program can be started from within the Programming-Environment and
errors may be found using a debugger. The debugging-environment allows
the user to set and unset breakpoints directly in the source code. The
contents of variables may be displayed in a special window, the Watch-
Window. This window is updated while reaching a breakpoint. The Stack-
Window displays the program stack.
Help is available for xwpe and the man-pages installed on the system
may be displayed. All this can be reached via the help-functions.
The editor may be used to edit up to 35 files at the same time. They
are all displayed in a window of their own. A mouse is used to select
special editor functions from the top menu. These functions can also
be selected by hitting a special key or combinations of keys. Some of
these features are a complete search and replace function (yes, it can
search for regular expressions) and a file-manager. The file-manager is
used to open, copy, rename and move or delete files.
The X-window programming environment can be used without the special
programming features. If it is invoked as ‘xwe’ (‘we’ if used with a
character terminal) it can be used as an editor e.g. for shell-
programming.
OPTIONS
-pm The next file is a message-file.
-r Start xwpe in the recover mode. The internal buffers are saved
in files with the postfix ‘.ESV’ in the name if a signal is
caught by xwpe (except for SIGKILL). If the editor is invoked
with the ‘-r’ option is specified in the command line, the old
session will be recovered.
-sf file
file will be used instead of the personal option file,
$HOME/.xwpe/xwperc.
-so The default options are used. The option file will not be read.
The following standard X command line options are available for the X-
Window versions.
-display display
This option specifies the X server to contact; see X(1).
-font font, -fn font
The font to used for the text can be specified with this option.
The default is 8x13.
-geometry geometry, -g geometry
This option specifies the preferred size and and position of the
editor; see X(1).
-iconic
This indicates that xwpe should ask the window manager to start
as icon rather than a normal window.
-pcmap This starts xwpe with a private colormap.
INVOCATION
On startup (subject to the -sf and -so options), xwpe reads the
personal initialization file $HOME/.xwpe/xwperc. If no such file
exists, the system wide initialization file,
/usr/local/lib/xwpe/xwperc, is read. If neither file exists, the
default options will be used.
xwperc is a text file written by the programming environment. Although
modification by hand is possible comments will be erased if the options
are latter saved from within xwpe.
RESOURCES
The following resources are available. The application name is either
"xwe" or "xwpe". Both belong to the "Xwpe" class.
font (class Font)
Specifies the name of the font to use. The default is ‘‘8x13.’’
geometry (class Geometry)
Specifies the preferred size and position of the editor. Sizes
of less than 80 x 25 are ignored.
color1 (class Color1)
...
color16 (class Color16)
xwpe uses 16 colors. The default setting is similar to the PC-
color set.
SYNTAX-SUPPORT:
Xwpe supports the syntax of a language by using different colors to
display keywords, constants, preprocessor, comments, operators and
everything else. This support is defined already for the programming
languages C, C++, and FORTRAN. More languages can be added to the
user’s syntax definition file, $HOME/.xwpe/syntax_def. The syntax of
any predefined language can also be overridden. If no personal syntax
definition file exists, the system definition file,
/usr/local/lib/xwpe/syntax_def, will be used.
Each syntax highlighting is distinguished by the file extension. The
syntax_def uses the following format for language definition.
"string: The postfix for the filename."
"integer: The number of keywords."
"strings: The keywords."
"integer: Number of operators with more than one
character length."
"strings: Operators with more than one character
length."
"string: Operators containing one character."
"string: Beginning of comment"
"string: End of comment"
"string: Beginning of comment reaching until the end
of the line."
"string: Characters used for comments depending on the
column."
"string: Special single characters."
"integer: Column for comments (-1 for none)."
"integer: Column for continuing line (-1 for none)"
"Integer: Column for comment till the end of line (1000
for none)"
Strings and integers are separated by blanks or carriage returns. The
strings used for single character operators and for column depending
comments must not contain blanks. All strings used for comments can
contain NULL to indicate that there is no such comment. An integer can
be zero if there is no keyword or multiple character operators. The
string for special single characters contains the following fields:
Character for string-constants
Character for character-constants
Character for preprocessor-commands
Character for quoting the next character
Character for next line is continuing line
(if it is the last character in the line)
Character (if not empty: the language is not
case sensitive)
If one character is not defined (e.g. missing) a blank is inserted at
the corresponding position.

BUGS
Debugging leaks memory. The exact cause is still unknown.
Unsure if the column for continuing previous line is working.
Information on how to test this and what the result should be would be
greatly appreciated.
Documentation hasn’t been updated.
Compilers are assumed to have a -c and -o option. This causes problems
for those who wish to use java, perl, or other languages.
make install installs x versions even if not compiled in.
Adding items when no project is open has odd behavior.
Changing the maximum column and using cut & paste can crash xwpe.
Clicking "edit" in the project menu when not on a file it loads a file
with a name of " ".
Esc key requires 3 presses to do the regular escape function under
Linux console (and perhaps other terminal types).
No error for disk full.
Check headers doesn’t correctly handle comments and "ifndef"
protection.
