Notice that the long lines in the Macaulay2 window, instead of being wrapped around to the next line, simply disappear off the right side of the screen, as indicated by the dollar signs or little arrows in the rightmost column. Setting printWidth to zero removes line wrapping in the buffer, sometimes useful to view large matrices.
AQUAMACS COMMAND KEY META CODE
Execute the following line of code (put it in your foo.m2 buffer, and then press f11) printWidth=0 random(R^20,R^) Now let's see how we can handle wide and tall Macaulay2 output. Or edit it slightly to change it before pressing return. When you get to one you'd like to run again, simply press return to do so. Position your cursor at the end of the buffer, and then use M-p and M-n to move to the previous and next line of input remembered in the history. (On the mac, hold down the option key while clicking the mouse)Įxperiment with command line history in the *M2* buffer. Alternatively, if you have a mouse, use the middle button to select the desired completion. Switch to it with the F8 key, move to the desired completion, select it with the RETURN key, and then return to the *M2* buffer with C-x o.
The possible completions are displayed in a window.
Delete the word with M-DEL, type res and then press the TAB key. Notice how the word is completed to resolution for you. Now go to the very end of the *M2* buffer with M-> and experiment with keyword completion. If you select several lines using the mouse, then pressing f11 will present the entire selection to Macaulay2. Position the cursor on the first line of code, and press the f11 function key repeatedly to present each line to Macaulay2. If you wish, save the file using C-x C-s. m2 is important, as it informs emacs to use the Macaulay2 mode). Now create (using C-x C-f) a file, named something like foo.m2 (the final. 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. Solomon's, which can interfere with emacs when it tries to run a subprocess.
AQUAMACS COMMAND KEY META SOFTWARE
A third reason may be that you are in Windows-98 and are using anti-virus software such as Dr. Another reason may be that you have not installed Macaulay2 properly - the startup script ( M2 or M2.bat) should be on your path. If f12 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 f12 key or type M-x M2 to start up Macaulay2 in a buffer named *M2*. Use the keystrokes C-x 2 to divide the buffer containing this file into two windows. Similarly, C-c means to press the c key while holding down the control key, and C-x 2 means to press x while holding down the control key, then to press 2 this time do not press enter. Sending lines or selected text to Macaulay2 using the f11 keyīefore starting, note that when we say to type M-x M2, what we really mean is: press the x key while holding down the meta key (on Macs this is either the option key or the apple key, depending on how your emacs is set up) type M2 and then press the return (or enter) key after that. Starting Macaulay2 with the f12 key, or with M-x M2 The aspects of this interface that we describe include For the rest of this section, we assume that you are running emacs. emacs file mentioned there, you need to exit and restart emacs. We assume that you have already set up this interface, as described in setting up the Macaulay2 emacs interface.

In this section, we show by example how to use the Macaulay2 emacs interface.
