Subject: PENG 2.1 Released
Date: 22 Feb 2000, 00:31:06
Hi, everybody!
This is to announce the release of PENG 2.1. PENG is an Integrated
Development Environment written in and for GPC.
PENG was written completely in Pascal and created using GPC. It is
well suited for editing and compiling Pascal programs with GPC,
though its functionality is not Pascal specific, and it can just as
well be used for writing C, HTML, TeX, Texinfo, E-Mail or any other
ASCII based format. PENG was developed and tested mainly under
Linux/x86, but also under DJGPP and Solaris.
The main web site of PENG is <http://fjf.gnu.de/peng.html>. It
contains more extensive information about PENG, including the
complete documentation in HTML format, as well as download
facilities and a pointer to the PENG mailing list. The mailing list
is the recommended place for bug reports and requests about PENG.
The main changes since PENG 2.0 are the following. They are
documented in more detail in PENG's online help.
- Some minor bug fixes and improvements in some details
- Made some aspects of the "look and feel" easier and more
consistent
- PENG also accepts long options on the command line now
- PENG's example tools and variables are now built into PENG, and
their documentation was merged into the PENG manual. The built-in
tools and variables can be dumped to a file with the `-d' or
`--dump-tools' option, and their automatic use can be suppressed
with the `-N' or `--no-builtin-tools' option, so PENG's tools and
variables remain fully customizable.
- Support for progress messages and a progress bar while running
tools
- Lex highlighting for different languages, case sensitive or
insensitive
- Speeded up the opening of info files without tag tables
- `<ALT>-<SPACE>' (non-breaking space) now also works under X11 and
DJGPP.
- Deleting words with `<CTRL>-<T>' now also works in string input
boxes.
- Easier and better customizable color selection
- Menu `Options/Editor' split into two menus (`Options/Editor1' and
`Options/Editor2') because it was growing too large
- New option to show the line numbers in the text editor (menu items
`Options/Editor1/Line numbers', `Options/Editor2/Line number
width', `Options/Colors/Editor/Line number')
- New tool output redirections `#p', `#P' ("parallel")
- Under Linux, PENG now recognizes shifted function keys if you have
new keytables (e.g. console-data-1999.xx.xx) which come with
recent versions of the distributions. However, if you still have
the old keytables and PENG doesn't recognize, e.g., `<SHIFT>-<F1>'
anymore, you'll have to upgrade them if you need shifted function
keys (the change doesn't affect other keys, so PENG will be far
from unusable even with the wrong version of keytables).
Note, there are some changes which could require a few users to do
some manual changes, but should be beneficial to most. First-time
PENG users do not need to care about the following:
- The names of the automatically loaded config files have changed.
They are now `/etc/peng.conf' and `~/.peng' under Unix. Under Dos,
they are `peng.ini', either in the directory `$DJDIR\etc\' (if
DJGPP is installed) or in the directory where `peng.exe' is
installed, and `peng.cfg', either in the directory `$HOME' (if you
set the environment variable `HOME') or in the directory where
`peng.exe' is installed.
- Since PENG's example tools and variables are now built into PENG,
if you installed the `pengrc' file before, please delete it now,
to avoid confusion. If you made changes to the file, you might
have to extract them to a new config file.
- Since the documentation of the built-in tools was merged into
PENG's manual, if you installed pengtools.info before, please
delete it now to avoid confusion.
- The `viewdvi' script is no more needed. Its functionality has been
included into the respective PENG tools itself. If you installed
the script before, you can delete it now, but you can as well keep
it if you like. If you made changes to the script, you'll have to
change the respective PENG tools now.
- PENG's color selection has been extended. On the one hand, there
are more colors to choose, so you can customize your colors in
more detail (e.g., different colors for the main menu and submenus
if you like). On the other hand, most colors now can be unselected
(and many are unselected by default), and PENG will automatically
use the next appropriate one then. E.g., the colors for the main
menu are unselected by default, and PENG will use the same colors
as for submenus by default. Similarly, the backgound color of most
items in the text editor now defaults to that of normal text, so
you can change the background in a single place rather than having
to change several items. More details can be found in the online
help for `Options/Colors'.
While all this will make your color selection easier and better
customizable, it might change your previous color selections
slightly because of unexpected influence of the "next" color
mechanism. This should be easy to correct by setting the right
colors.
Furthermore, this change required slight changes to PENG's config
file format. You can convert your old config files with the script
below. If you don't want to do it (e.g., because you don't have
awk and you're too lazy to install it ;-), you can load the old
config files and ignore the warnings. You will lose your color
selections, nothing more.
#!/bin/sh
if [ $# == 0 ]; then
echo "$0: no arguments given" >&2
exit 1
fi
if test -z "$AWK" ; then
for AWK in gawk nawk awk ""; do
if type $AWK 2>&1 | grep 'not found' > /dev/null 2>&1; then
else
break
fi
done
fi
if test -z "$AWK" ; then
echo 'No awk found.' >& 2
exit 1
fi
for a do
if [ ! -f "$a" ]; then
echo "$a does not exist"
elif [ `grep -c '^ProgramVersion="[^"]*", 6' "$a"` != 1 ]; then
echo "$a is not a PENG config file, version 6"
else
$AWK '
/^ProgramVersion=/ { sub ("=.*", "=\"PENG config converter\", 7") }
/^Color Progress message=/ { sub ("^Color Progress message=", "Color Activity message=") }
/^Color Editor Non breaking space=/ { sub ("^Color Editor Non breaking space=", "Color Editor Non-breaking space=") }
/^Color/ { c = $0;
sub ("[^=]*=", "", c);
x = c;
sub (",.*", "", c);
sub ("[^,]*,", "", x);
sub (",.*", "", x);
if (c + 0 >= 0) c = sprintf ("%i, %i", c % 16, c / 16);
if (x + 0 >= 0) x = sprintf ("%i, %i", x % 16, x / 16);
sub ("=.*,", "=" c ", " x ",")
}
{ print }
' < "$a" > "$a.conv"
mv -f "$a.conv" "$a"
echo "$a converted"
fi
done
Have much fun with PENG,
Frank
