I am in a transition period where I am moving from sjasmplus to another assembler.
Some of my projects use several instructions per lines, which is not recognized by all the assembler.

You'll find in this message a function, allowing to change a line formatted like that:


    inst 1 : inst 2 : inst 3

into something like that:


    inst 1

    inst 2

    inst 3


If you want to change one line, type (of course autocompletion allow you to type just the first characters of the function):


:call CPCSplitInstructionsInSeveralLines()


If you want to change all the similar occurence in the file, type:


:%call CPCSplitInstructionsInSeveralLines()



Here is the function to add in the file ~/.vim/ftplugin/z80.vim



" Split a line with several commands in several independant lines

" (allow to easily convert files from one assembly language to another one)

function! CPCSplitInstructionsInSeveralLines() range



    let lnum          = a:firstline

    let s:linecounter = 0



    while lnum <= a:lastline

        let s:line = getline(lnum + s:linecounter)



        " Works only on right lines

        if  -1 == match(s:line, '.*:.*')

            let lnum = lnum + 1

            continue

        endif





        let s:instructions = split(s:line, ':')

        let s:empty = matchstr(s:line, '^\s*')

        let s:code = substitute(s:line, '^\s*\(.*$\)', '\1', '')

        let s:i=1





        call append(lnum + s:linecounter, s:empty.'; '.s:code.' {{{ Automatic expanding')

        " Copy each instruction

        for instruction in s:instructions

            if s:i == 1

                call append(lnum+s:i+s:linecounter, instruction)

            else

                call append(lnum+s:i+s:linecounter, s:empty.instruction)

            endif

            let s:i=s:i +1

        endfor

        call append(lnum+s:i+s:linecounter, s:empty.'; }}}')

        

        " Delete line

        exec (lnum+s:linecounter)."d"



        let s:linecounter = s:linecounter + s:i 

        let lnum = lnum + 1

    endwhile

I will not more pollute the forum with this subject which interest nobody except me ;)

I have published a repository with my CPC editor configuration which will evolve with my needs.
If one day, someone is interested, it is here:
https://github.com/rgiot/vim-z80-democoding

You're not the only one interested :) Just I don't have the time :(

Why another repository ? Why not use cpcsdk one ?

And yes, we are reading :)

@pulko:
- I am in a period were I prefer small repositories for one task, than big repositories with tons of things.
- I want to address this work to any people coding in z80, not only CPC demosceners
- git is marvelous
- do not hesitate to fork it if you want
- I fell ridiculous with my small number of commits on cpcsdk ;)

@cloud:
- yes, we are three to be interested ;) Maybe 3 is a bigger figure than half of the number of real active cpc sceners ;)

Useful tip from Pulko, hidden in the intraweb.
I'll probably use it

I didn't expect anyone else to do more than z80 :)

VIM is now able to detect minor z80 syntax error using the syntastic plugin (repository version):
https://github.com/scrooloose/syntastic

The z80 parser must be installed before
https://github.com/rgiot/pycpcdemotools/blob/master/cpcdemotools/source_checker/z80_syntax_checker.py

Fell free to improve the process
