Formatting MMIXAL source code.

mmixal-fmt is a tool for formatting MMIXAL source code.

Installation

make
make install

By default, the mmixal-fmt will be installed in /usr/local/bin/

Usage

mmixal-fmt will read MMIXAL (MMIX Assemble Language) from stdin and output to the stdout. In fact, this tool is intended to integrate with this vim plugin.

Assuming below is what mmix.mms contains

 % Example program to format
L IS 500        This is comment
t  IS $255   This is another comment
n GREG      % Comment
r GREG  // Comment
jj GREG 0        Comment
   PBN mm,2B
 LDA t,NewLn; TRAP 0,Fputs,StdOut
 CMP t,mm,2*(L/10-1A) ; PBNZ t,3B;       TRAP 0,Halt,0

After executing cat mmix.mms | mmixal-fmt, the output will be

% Example program to format
L   IS    500               This is comment
t   IS    $255              This is another comment
n   GREG                    % Comment
r   GREG                    // Comment
jj  GREG  0                 Comment
    PBN   mm,2B
    LDA   t,NewLn
    TRAP  0,Fputs,StdOut
    CMP   t,mm,2*(L/10-1A)
    PBNZ  t,3B
    TRAP  0,Halt,0

And this

t is $255
    LOC Data_Segment
    Greg @ Base Address
string BYTE "Hello, World!",#a,0

    LOc #100
Main LDA t,string
    TRAP 0,Fputs,StdOut
    Trap 0,Halt,0

Will be formatted as

t       IS    $255
        LOC   Data_Segment
        GREG  @                     Base Address
string  BYTE  "Hello, World!",#a,0

        LOC   #100
Main    LDA   t,string
        TRAP  0,Fputs,StdOut
        TRAP  0,Halt,0
