Edit your current shell command inside a scratch buffer.
nvim-editcommand provides similar functionality to fc or <c-x><c-e>/Ctrl-x,Ctrl-e, allowing the user to edit their current shell command in an editor.
The reason a user may want to do this is that it allows them to access the editors functionality that may not be available on the command line.
It also allows the user to edit command in shell's that may not otherwise provide the same functionality, e.g. python/ruby interpreters.
The command before and after editing can be accessed via the global variables g:editcommand_before and g:editcommand_after.
nvim-editcommand would be useful for a Neovim user who is running their shell inside a Neovim terminal buffer. In such a situation <c-x><c-e> is still available but (assuming your $EDITOR is nvim) it will have to open a new Neovim instance inside the terminal inside the existing Neovim instance, which can quickly become rather cumbersome to navigate in and out of.
call plug#begin('~/.nvim/plugged')
Plug 'brettanomyces/nvim-editcommand'
...
call plug#end()User should set g:editcommand_prompt to their shell prompt
let g:editcommand_prompt = '>' " default is '$'The default mapping is <c-x><c-e> however you may disable this mapping by setting
let g:editcommand_no_mappings = 1 " default is 0To provide you own mapping provide a terminal mapping to <Plug>EditCommand
tmap <c-x> <Plug>EditCommand " default is <c-x><c-e>To use a temporary file rather than a scratch buffer set g:editcommand_use_temp_file
let g:editcommand_use_temp_file = 1 " default is 0The scratch buffer cannot be saved, use :close or :bdelete or :quit.
If using a temporary file the command will only be copied back if you save first :wquit.
The command in the buffer will be saved to g:editcommand_after by an autocmd which then removes itself. When the terminal buffer is re-entered the command is copied to the commandline by another autocmd which also removes itself.
