XEmacs
Editors in the Linux environment are usually completely separated from compilers and compiler tools, such as make. Source code is written with a text editor and the source file is compiled afterwards.
There are also editors that integrate compilers so that the compiling can be carried out within the editor. One such editor is XEmacs. In order to use XEmacs conveniently, the .profile file in user's home directory should contain the following lines:
PATH="$PATH:/opt/xemacs/bin"
export PATH
After this modification XEmacs editor can be executed with a command xemacs. For additional information on XEmacs, please visit www.xemacs.org.
