Yet simple tool to paste images into markdown files
You are editing a markdown file and have an image on the clipboard and want to paste it into the document as the text . Instead of first copying it to that directory, you want to do it with a single <leader>p key press in Vim. So it hooks <leader>p, checks if you are editing a Markdown file, saves the image from the clipboard to the location img/image1.png, and inserts  into the file.
By default, the location of the saved file (img/image1.png) and the in-text reference ( are identical. You can change this behavior by specyfing an absolute path to save the file (let g:mdip_imgdir_absolute = /absolute/path/to/imgdir on linux) and a different path for in-text references (let g:mdip_imgdir_intext = /relative/path/to/imgdir on linux).
Using Vundle
Plugin 'img-paste-devs/img-paste.vim'
Add to .vimrc
autocmd FileType markdown nmap <buffer><silent> <leader>p :call mdip#MarkdownClipboardImage()<CR>
" there are some defaults for image directory and image name, you can change them
" let g:mdip_imgdir = 'img'
" let g:mdip_imgname = 'image'
Simply add a custom paste function that accepts the relative path to the image as an argument, and set g:PasteImageFunction to the name of your function. E.g.
function! g:LatexPasteImage(relpath)
execute "normal! i\\includegraphics{" . a:relpath . "}\r\\caption{I"
let ipos = getcurpos()
execute "normal! a" . "mage}"
call setpos('.', ipos)
execute "normal! ve\<C-g>"
endfunction
Then in your .vimrc:
autocmd FileType markdown let g:PasteImageFunction = 'g:MarkdownPasteImage'
autocmd FileType tex let g:PasteImageFunction = 'g:LatexPasteImage'
The former sets the (default) markdown paste function for markdown files, while the latter sets the new latex paste function to be used in latex/tex files. The above LatesPasteImage has already been added to the plugin, see plugin/mdip.vim. Existing paste functions:
Finally, add the file type (e.g. tex) to the first line you added, as
autocmd FileType markdown,tex nmap <buffer><silent> <leader>p :call mdip#MarkdownClipboardImage()<CR>
'----'
| Filetype | Function name | Content |
|---|---|---|
| Markdown | MarkdownPasteImage |  |
| Latex | LatexPasteImage | \includegraphics{path} \caption{Image} |
| N/A | EmptyPasteImage | path |
PRs welcome
This plugin gets clipboard content by running the xclip command.
install xclip first.
Set your WSL path in .vimrc (you can check your WSL path from Windows File Explorer)
let g:mdip_wsl_path = '\\\\wsl.localhost\\Ubuntu-22.04'
I'm not yet perfect at writing vim plugins but I managed to do it. Thanks to Karl Yngve Lervåg and Rich for help on vi.stackexchange.com where they proposed a solution for my use case.
