Configuring emacs

Configuring emacs#

Run in terminal by default#

Instead of having to remember to add -nw to the emacs command, we can add the following to our .bashrc file to have it run that way each time:

emacs() { command emacs -nw "$@"; }

You can add this at the very end of the file (on its own line).

Important

Be sure the end your .bashrc with a newline (i.e., pressing the “enter” key after adding the above line).

.emacs configuration file#

On portal or portal2, you can add the following .emacs file to your home directory to setup some C++ support:

.emacs

Tip

An easy way to put this on the remote server is to right-click the link and select “copy link”, and then on the remote machine, do:

wget <paste-link-here>

where you paste the link you copied, as indicated.

you can check that the file is in the right place by doing:

ls -l ~/.emacs

if it says No such file or directory that it is not installed properly.

This will allow us to use the flycheck package for C++. To enable this do the following:

  • Start emacs:

    emacs -nw

  • In emacs, enter the command:

    M-x package-install

    press the “enter” key, and then type:

    flycheck

  • exit emacs (C-x C-c)

Try it…

Let’s write a “hello word”, but leave off a ; and see how flycheck catches this.
