Press M-f11 with your cursor in this buffer to designate it as the source for the Macaulay2 commands. Visit a file called foo.m2 and paste the following text into it.
#Aquamacs macaulay2 code#
Here is a way to conduct a demo of Macaulay2 in which the code to be submitted is not visible on the screen. Notice that the input prompts are not submitted to Macaulay2. Now paste the following text into a buffer, unless you have the ASCII version of this documentation in an emacs buffer already, position the cursor on the first line of code, and press the f11 function key repeatedly to present each line to Macaulay2. Verify that Macaulay2 is running by entering a command such as 2+2. You may use C-x o freely to switch from one window to the other. For example, the following emacs code will bind it to the function key f11. You may wish to bind the emacs function M2-send-to-program to a global keystroke for ease of use this is done automatically for in Macaulay2 buffers.
#Aquamacs macaulay2 how to#
(The notation M-x is emacs notation for pressing the x key while holding down the Meta or Alt key.) If that doesn't work, please see teaching emacs how to find M2-init.el and teaching emacs how to find M2.
If this doesn't start up Macaulay2, one reason may be that your function keys are not operable. (The command line used to start Macaulay2 may be edited before being run if you use a prefix argument with the above command: press C-u just before.) Then press the M-x M2 to start up Macaulay2 in a buffer named *M2*. If you are reading this file with emacs, then use the keystrokes C-x 2 to divide the buffer containing this file into two windows. The only reason we recommend the use of this mode is so the same key can be used to evaluate a line or a region of code, depending on whether the region is active.Įxit and restart emacs with your new initialization file. The set-mark function or the exchange-point-and-mark function will activate the mark, and it will remain active until some change occurs to the buffer.
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.
#Aquamacs macaulay2 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 demonstrations 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. 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.
