Vim9Script VLANG REPL
Vim9Script REPL¶
An easy method to achieve bidirectional communication between Python and Vim by using temporary text files. From https://github.com/mattn/vim_kernel
In [15]:
# import relevant modules
from subprocess import Popen,PIPE,STDOUT
from os import environ,remove
import json
import shutil
In [16]:
# The path to vim90 - Windows
vim_exe_path = "C:\\Users\\Seve\\Vim\\vim90\\vim.exe"
In [17]:
vim = Popen([vim_exe_path,
'-X',
'-N',
'-u',
'NONE',
'-i',
'NONE',
'-e',
'-s',
'-S',
'kernel.vim'
], stdout=PIPE, stderr=STDOUT, shell=False, env=environ.copy())
Pass a vim9script to VIM (stdin)¶
In [18]:
with open(str(vim.pid)+".input", 'w', encoding='utf-8') as f:
f.write("""
vim9script
def VimNew(): number
var sum = 0
for i in range(1, 29999)
sum += i
endfor
return sum
enddef
var start = reltime()
echo VimNew()
echo 'Vim new: ' .. reltimestr(reltime(start))
""")
Read stdout¶
In [19]:
with open(str(vim.pid)+".output", 'r', encoding='utf-8') as f:
output = json.loads(f.read())
In [20]:
output
Out[20]:
{'stderr': '', 'stdout': '449985000\nVim new: 0.003460'} In [21]:
remove(str(vim.pid)+".output")

Get Tailwind CSS¶
Set path for the V compiler
In [3]:
v_exe_path = "C:\\Users\\Seve\\workplace\\v\\v.exe"
AssertionError if the V compiler isn't installed
In [4]:
assert shutil.which(v_exe_path) is not None
In [14]:
v = Popen([v_exe_path,
'run',
'kernel.v'
], stdout=PIPE, stderr=STDOUT, shell=False, env=environ.copy())
with open("1.v", 'w', encoding='utf-8') as f:
f.write("""
// V snippet
mut nums := [1, 3, 5, 7]
println("List of integers $nums") // [1, 3, 5, 7]
""")
In [10]:
%%javascript
$.ajaxSetup({ cache: false })
function UpdateVdiv(){
$.getJSON("./1.output",
function(data){
var now = new Date().toString().split("GMT")[0];
$('#content').html(data.stdout);
$('#timeupdate').html('Last updated:'+ now);
}
);
}
setInterval(UpdateVdiv, 1000);
