The effect of this is that the mark is only active occasionally, and then emacs functions that act on a region of text will refuse to proceed unless the mark is active. It sets the variable transient-mark-mode to have a different value in each buffer, and sets hooks so that transient-mark-mode will be set to t in M2 buffers.

It will also provide a special mode for running Macaulay2 in an emacs buffer. Loading that file will cause emacs to enter a special mode for editing Macaulay2 code whenever a file whose name has the form *.m2 is encountered. We assume you have taught emacs how to find Macaulay2's files, as described in the previous sections, and that emacs is loading the file M2-init.el successfully.

Once you have spent an hour with the emacs tutorial and manual, come back and continue from this point. It is cheap, comprehensive and informative. You may also want to purchase (or print out) the emacs manual. After running through that you will want to examine the online emacs manual that can be read with info mode you may enter or re-enter that mode with the keystrokes C-h i. (The notation C-h indicates that you should type Control-H, by holding down the control key, and pressing H.) The emacs tutorial will introduce you to the basic keystrokes useful with emacs. If you are a newcomer to emacs, start up emacs with the command emacs and then start up the emacs tutorial with the keystrokes C-h t. It might be useful for you to visit that file with emacs now, thereby avoiding having to cut and paste bits of text into emacs buffers for the deomonstrations below. There is an ASCII version of this section of the documentation distributed in the file share/emacs/site-lisp/macaulay2/M2-emacs-help.txt. It also provides for dynamic completion of symbols in the language. We provide a package for emacs that implements this. Secondly, get X server running with emacs GUI 1.Because some answers can be very wide, it is a good idea to run Macaulay2 in a window that does not wrap output lines and allows the user to scroll horizontally to see the rest of the output. Tip: use the command in bash 'lsb_release -a' to retrieve your Ubuntu's version. Hit Start then type 'bash', or open command prompt and type 'bash'. Get 'bash' for Windows and M2: 1.) Get Ubuntu 'bash' in cmd Install 'Linux subsystem for Windows' with ubuntu.įollow instructions: 2.) Open Ubuntu bash. See the following sections for the steps for installation of, firstly, the Linux subsystem then M2, followed by installing and setting up an X server with emacs coupled with M2. However, Windows 10 for developers and insider builds come with a new feature, 'Linux subsystem for Windows'. For most Windows distro-s, use Cygwin to get Linux bash and through that, M2 command to start Macaulay2. Macaulay 2, M2 for short, currently is mainly developed for Linux distros.
