When writing Greek, sigmas at the ends of words should have a different form. Can I do something automatically to replace: μῖσοσ by μῖσος, and so in all such cases?

    How about running %s/σ\>/ς/g whenever you save the file?

  • Yes, but it would be better to have it corrected straight away.

    It's even better to write it correctly from the start :P You could use (greek) dictionary-based autocompletion

    The problem is distinguishing an end-of-word sigma from a normal one. I think you'll have to content yourself with typing some other key combination at the end of word (say inoremap σ<spac> ς), then any sigma followed by space will be replaced by the other form. But then you'd have to add another space manually.

Since a final sigma is quickly followed with a space even if a punctuation marks immediately followf it (except for the end-of-line case), you could do this: define the folowwing function (in your ~/.vimrc file) and remap the space key in insert mode to this function.

" The function checks whether a final greek sigma to be fixed can be found
" on the same line at the left of the cursor; the function should be accessed
" through a mapping of the space key in insert mode (since even punctuation
" marks are flollowed with a space.
function! FixPreviousSigma()
    let l:l = line(".")
    let l:c = col(".")
    let l:s = search('σ\>', 'bcW', l:l)
    if l:s == l:l
        silent execute "normal rς"
    endif
    call cursor(l:l, l:c)
endfunction

Then use the tricky mapping whenever you need to use this feature:

:inoremap <Space> <ESC>:call FixPreviousSigma()<CR>a<C-v><Space>

If you also want to take into account the end-of-line case, maybe you could also try:

:inoremap <Enter> <ESC>:callFixPreviousSigma()<CR>o

A little late to the party but literally my solution has to do with a patch of vim from the last week.Due to some case folding issues vim spell checker was handling all final ς as σ.Now you can normally spellcheck greek words (if you build the latest vim from source at least at patch 8.2.2974). So here is a guide for that and a good greek dictionary: Run from wherever

  1. mkdir ~/example_spell
  2. cd ~/example_spell
  3. wget https://raw.githubusercontent.com/wooorm/dictionaries/main/dictionaries/el/index.dic
  4. wget https://raw.githubusercontent.com/wooorm/dictionaries/main/dictionaries/el/index.aff
  5. vim
  6. in vim command mode type :mkspell el2 ~/example_spell/index
  7. then exit vim and type : mkdir ~/.vim/spell
  8. cp -r ~/example_spell ~/.vim/spell

Lastly on your file of interest in vim :set spell spelllang=el2 And z= over greek words.

All of that thanks to Bram Moolenaar taking the time to learn a greek syntax rule just for the sake of good software
