How about adding an autocmd
to your ~/.vimrc
-file, creating a mapping:
autocmd FileType python map <buffer> <F9> :w<CR>:exec '!python3' shellescape(@%, 1)<CR>
autocmd FileType python imap <buffer> <F9> <esc>:w<CR>:exec '!python3' shellescape(@%, 1)<CR>
then you could press <F9>
to execute the current buffer with python
Explanation:
autocmd
: command that Vim will execute automatically on {event}
(here: if you open a python file)
[i]map
: creates a keyboard shortcut to <F9>
in insert/normal mode
<buffer>
: If multiple buffers/files are open: just use the active one
<esc>
: leaving insert mode
:w<CR>
: saves your file
!
: runs the following command in your shell (try :!ls
)
%
: is replaced by the filename of your active buffer. But since it can contain things like whitespace and other "bad" stuff it is better practise not to write :python %
, but use:
shellescape
: escape the special characters. The 1
means with a backslash
TL;DR: The first line will work in normal mode and once you press <F9>
it first saves your file and then run the file with python.
The second does the same thing, but leaves insert mode first
