Evaluate VimL

Eval Vim language

UPD

Vim9 has updated source command that can source not only the file but buffer lines, in a simplest form it is just a :source to evaluate whole buffer, :.source to evaluate current line.

Thus, simplified version of this plugin could be put into your .vimrc:

vim9script
# source vimscript (operator)
def SourceVim(...args: list<any>): any
    if len(args) == 0
        &opfunc = matchstr(expand('<stack>'), '[^. ]*\ze[')
        return 'g@'
    endif
    if getline(1) =~ '^vim9script$'
        vim9cmd :'[,']source
    else
        :'[,']source
    endif
    return ''
enddef
nnoremap <silent> <expr> <space>v SourceVim()
xnoremap <silent> <expr> <space>v SourceVim()
nnoremap <silent> <expr> <space>vv SourceVim() .. '_'

---

Run vimscript from anywhere in vim and save output to * (clipboard) register.

Installation

minpac

somewhere in .vimrc

call minpac#init()
" ...
" more plugins
" ...
call minpac#add('habamax/vim-evalvim')

Then :call minpac#update() to install it.

vim-plug

somewhere in .vimrc

call plug#begin('~/.vim/plugged')
" ...
" more plugins
" ...
Plug 'habamax/vim-evalvim'

Usage

There are no default mappings, add your own, for example:

xmap <leader>v <Plug>(EvalVim)
nmap <leader>v <Plug>(EvalVim)
omap <leader>v <Plug>(EvalVim)
nmap <leader>vv <Plug>(EvalVimLine)

Then having somewhere in your buffer add:

echo "hello world"

• <leader>vv to evaluate current line

• You should see hello world printed below

fun! TestFun(p)
    return a:p
endfun
echomsg TestFun("Another Hello!")

• <leader>vip to evaluate current paragraph

• You should see Another Hello printed below

Note	You can also visually select text block and evaluate it with <leader>v. Although you will not see the message printed — you can find it in :messages.

set nu!
set cursorline!
set cursorcolumn!

• <leader>vip to evaluate current paragraph of settings

• line numbers, cursorline and cursorcolumns will be toggled

Settings

By default all output is captured to * and " registers so you can paste it when needed.

To turn it off use:

let g:evalvim_capture_output = 0

vim-evalvim's Issues

Multiline execution fails on unterminated quotes

Issue running commands with multiline strings. Issue occurs regardless of single or double quotes.

Tested with keybindings as listed in the README.md, #Usage:
  <leader>vap - Run this plugin with all the current paragraph

Content in Vim buffer:

echo "line 1
line 2
line 3"

Expected result:

line 1
line 2
line 3

Actual result is an Error:

Error detected while processing function evalvim#run:
line   32:
E114: Missing double quote: "line 1

For comparison running directly in terminal works as expected:

bash -c 'echo "line 1
line 2
line 3" '

I am on evalvim.vim,
