starting swank with ros run

[kranerup]

I manage my sbcl versions with ros so I'd like to be able to start sbcl with "ros run" command.
If I use g:slimv_swank_cmd then I need to provide the complete command line which must
point to the start-swank.lisp file and is installation dependent.

Instead I changed slimv-lisp.vim to support setting slimv_lisp to ros like this:
vim.g.slimv_lisp = 'ros run'
vim.g.slimv_impl = 'sbcl'

If there is a better way I'd like to know that.
If it is of interest I could provide my update to slimv-lisp.

TBH I have never heard about ros before. Is this roswell, a lisp implementation manager and launcher?

You could add these definitions (g:slimv_lisp and g:slimv_impl) to your .vimrc file, instead of modifying slimv-lisp.vim.

I was wondering if we could somehow add autodetection for ros in g:slimv_lisp, but I'm not sure how to do it so that we don't accidentally break things for other users. I suppose if ros and sbcl are installed then both ros and sbcl are valid commands. If we detect sbcl first, then we'll skip ros. If we detect ros first, then we'll change the functionality for existing users that have ros installed but did not want to use it with slimv or were happy using sbcl directly. If we add an option for this, then again we lose the meaning of autodetection.

What do you think?

Yes, ros is the command from roswell and ros run how to launch a repl. One feature of roswell is that it supports other lisps which makes it difficult for slimv to autodetect which lisp it is actually launching. Therefore I think that using roswell
will always require setting a variable saying which lisp it is. You are also right that sbcl command might coexist with ros making it difficult to know what a user would want in such a case.

What I use right now is what you suggested. I set g:slimv_lisp and g:slimv_impl in .vimrc. But the problem was that if I set g:slimv_lisp to ros run it will not work since ros run has a space in it. The command launched then becomes:
tmux new-window -n swank '"ros run" --load "/home/kenny/.local/share/nvim/lazy/slimv/slime/start-swank.lisp"'

What I then did was to change in slimv-lisp.vim so the quotes around ros run are removed when slimv_lisp is ros.

Ah, now I see, so the problem is the double quotes around "ros run", right?
How about the below solution in SlimvSwankLoader()?
We add the double quotes only if the lisp command contains whitespaces, and does not yet contain double quotes, and it is not a ros whatever command?

    let lisp = g:slimv_lisp
    if g:slimv_lisp =~ '\s' && g:slimv_lisp !~ '"' && g:slimv_lisp !~ '^\s*ros\s'
        " Make sure the lisp command is enclosed in double quotes in case it contains whitespaces
        " Except when using Roswell (e.g. ros run)
        let lisp = '"' . lisp . '"'
    endif

    " Build proper SWANK loader command for the Lisp implementation used
    if g:slimv_impl == 'sbcl' || g:slimv_impl == 'ecl'
        return lisp . ' --load "' . swanks[0] . '"'
    elseif g:slimv_impl == 'clisp'
        return lisp . ' -i "' . swanks[0] . '"'
    elseif g:slimv_impl == 'allegro'
        return lisp . ' -L "' . swanks[0] . '"'
    elseif g:slimv_impl == 'cmu'
        return lisp . ' -load "' . swanks[0] . '"'
    else
        return lisp . ' -l "' . swanks[0] . '"'
    endif

Yes, that looks good. I tried it with ros run and sbcl.
