I'm trying to use :ALEFix to run a fixer that is not pre-defined. For example, I might want to run foo -a -b index.html to format index.html with options -a and -b. foo does not read files from stdin, only by path.
I think the info is all in :h ale-fix, but as I'm not very good at Vimscript I haven't managed to do it. How can I?
