Variants of the VIsual iMproved Editor —vim

The vim editor, by Bram Moolenaar, is a text editor that is compatible with the original Berkeley Software Distribution vi editor by Bill Joy. An X11 version is called gvim and sports multiple scrolling windows and menus.Figure 14.1

The XEmacs editor features split windows, built-in help, a tutori­al, and other tools to help you be more pro­ductive.

Although the vim :version command shows that the systemwide vimrc and gvimrc resource files are located under the /usr/share/vim directory, this is not true: these files aren't installed with the vim package. However, you can create your own resource file after making changes to vim while running the editor and then using the :mkvimrc command. A resource file called .vimrc (which you can copy to .gvimrc) is created in your home directory and contains your changes. You can then edit and add your own commands, configurations, and menus to these files.

Several files and symbolic links to the vim editor are created on your system when you install the vim package from your CD-ROM:

• /usr/bin/vi -> /bin/vi

• /bin/vi -> /bin/vim

• /bin/view -> /bin/vim

• /usr/bin/view -> /bin/vim

• /bin/vim

• /usr/X11R6/bin/gvimThe vim editor, shown in Figure 14.2, is used as a replacement for the ex, vi, and view editors and is a visual editor supporting features such as cursor movement.

"ta"^mC^,elP.:

The vim editor features a number of improvements over the traditional vi editor, and has 23 different command-line options. In vim you can find built-in help, split-screen win­dows, block moves, command-line editing, horizontal scrolling, and word wrapping for word processing.

The gvim version of vim, used under the X Window System, has custom colors, window sizes, scrollbars, and menus. You can create your own set of menus containing specific vim commands and generate different versions of vim by saving your features in different gvim resource files. You can then use the -u command-line option to load a custom ver­sion.

Creating new menus for gvim is easy. You can, for example, group related macros or cus­tom commands you create in a separate menu. For details about building custom menus, read the files vim_menu.txt and vim_gui.txt under the /usr/share/vim directory.

Most of the documentation for vim is contained in its built-in help, and 21 text files in the /usr/share/vim directory contain extensive instructions.
