vim integration

In order to use mldz80 in vim you have to do the following:

Create a compiler file for mdlz80

In your vim configuration folder (usually ~/.vim) create a compiler/mdlz80optimizer.vim with the content:

if exists("b:current_compiler") | finish | endif
let b:current_compiler = "mdlz80optimizer"

if exists(":CompilerSet") != 2		" older Vim always used :setlocal
  command -nargs=* CompilerSet setlocal <args>
endif

let s:cpo_save = &cpo
set cpo&vim

CompilerSet makeprg=java\ -jar\ ~/bin/mdl.jar\ $*\ -dialect\ asmsx\ -po
CompilerSet errorformat=INFO:\ Pattern-based\ optimization\ in\ %f#%l:\ %m

let &cpo = s:cpo_save
unlet s:cpo_save

In the line makeprg set the command you'll use. In this case case: CompilerSet makeprg=java\ -jar\ ~/bin/mdl.jar\ $*\ -dialect\ asmsx\ -po Which means, use the mdl.jar found in /home/user/bin/, pass the files and use dialect asmsx (change this to match your assembler) and option -po.

Then when editing you need to set MDL as the compiler with :compiler mdlz80optimizer.vim and then you'll be able to analyze the file with :make file and check the optimizations with :copen.

Making it a bit more automatic

We can bind a key to process the file with mdlz80. In this example we're going to use F6.

In your vim config (.vimrc):

:nnoremap <F6> :compiler mdlz80optimizer \| :make % \| :cwindow <CR>

With this you'll be able to pass to mdlz80 the file, wait for it to end and then open the cwindow quickfix window to check the optimizations.

or if you want it to do the stuff in background with vim-dispatch:

:nnoremap <F6> :compiler mdlz80optimizer \| :Make %<CR>

This way requires a plugin but it's a bit more elegant in the UI sense.
