Improved Awk-mode for Emacs
Awk is perhaps the lightest programming language. However, light-weight as
it is, it's very gentle and powerful. Despite lots of popular programming
languages available, like many other programmers, I take awk as a DAILY tool and
like it the best.
The smallnest of awk makes it possible to add not so huge a menu to provide
almost all the essential parts of the language. The new awk-mode, thus, is
expected to make use of this advantage and turn Emacs into an awk-specific
integrated development environment (IDE).
The new awk-mode requires package, compile. Since Xemacs team has made some
modifications with the compile package, the Awk | Next/Previous/First Error do
not work currently. I'll try to update my code so as to have it work with both
Emacs and Xemacs soon if Xemacs users show their enthusiasm toward this new
Before you can enjoy the benefits this work can bring to you, you might need
to make sure that
- GNU awk, gawk, has been installed in your system and its path is covered
by the environment variable, PATH.
If you have certain version of awk rather than gawk, please rename it as
gawk (in MS Windows, gawk.exe).
- you had better have file, gawk.info. If you click Awk | Awk Manual and no
corresponding buffer appears, you need to set variable,
Info-default-directory-list, in your initialization file, .emacs, which is in
your home directory, by adding statement like
(setq Info-default-directory-list (cons "C:/cygwin/usr/info"
Special benefits for Windows users
You can obtain through Internet, gawk.hlp, a Windows help file, and put it
right in your home directory. By doing so, you can start gawk.hlp within
Emacs. In this case, you don't need gawk.info.
- Of course, awk-mode.el is put into the right directory. For example,
so on. Of course, you had better byte-compile it. At least, you NEED to delete
or move away the old awk-mode.elc from the directory mentioned.
- Emacs on Redhat Linux: /usr/share/emacs/20.7/lisp/progmodes
- Emacs on Windows: X:\emacs-21.2\lisp\progmodes
- XEmacs on Windows: X:\XEmacs\xemacs-packages\lisp\prog-modes
If you can not put awk-mode.el into the above directories because of
permission, you still have chance to use it. In this case, please modify your
initialization file, say, .emacs, in your home directory, by adding
(autoload 'awk-mode "~/awk-mode.el" "Awk editing mode." t)
Here, I suppose you copy awk-mode.el into your home directory.
THE FOLLOWING ARE SNAPSHOTS... SEE ATTACHED
A new menu, Awk, appears.
Submenus are helpful when you forget trivial but essential things, such as,
built-in functions and variables.
Click Awk | Run... to run your awk script and obtain the result or error
messages in the *running awk* window. While the awk code is running, you can
interrupt it at any time via Awk | Stop Running. And through Awk | Next Error,
Previous Error and/or First Error, you can browse your code wherever there exist
syntax errors. As you can see, it's now very easy for you to program, debug and
execute awk code.
