Emacs already helps you with editing +files, but Emacs can do much more. In particular, looking up +documentation is one of its strong points. Besides the info system +(which you are probably already using), mixal-mode defines commands +for getting particular information about a MIX operation code. + +With @kbd{M-x mixal-describe-operation-code} (or its keyboard shortcut +@kbd{C-h o}) you will get the documentation about a particular MIX +operation code. Keep in mind that these are not assembly (MIXAL) +pseudoinstructions. When the @code{point} is around a MIXAL +pseudoinstruction in your source file, Emacs will recognize it and +will suggest the right MIX operation code. + +@node Compiling and running, , Help system, mixal-mode.el +@comment node-name, next, previous, up +@section Compiling and running + +After you have written your MIXAL program, you'll probably want to +test it. This can be done with the MIX virtual machine. First you will +need to compile your code into MIX byte code. This can be done within +Emacs with the command @kbd{M-x compile} (@kbd{C-c c}). In case of +compilation errors, you can jump to the offending source code line +with @kbd{M-x next-error}. + +Once the program compiles without errors, you can debug or run +it. To invoke the debugger, use @kbd{M-x mixal-debug} (@kbd{C-c d}). +Emacs will open a @code{GUD} buffer where you can +use the debugging commands described in @xref{mixvm}. + +If you just want to execute the program, you can do so with @kbd{M-x +mixal-run} (@kbd{C-c r}). This will invoke mixvm, +execute the program and show its output in a separate buffer. |
