Re: passing vim9 vars to python3

Hi Bram,

Thank you I knew, this is working 

vim9script

def g:Py3_SimpleMinimalTest(yml_fpath: string): void
  w:yml_f = yml_fpath
  exe 'py3 print(sys.version)'
  exe 'py3 print(vim.current.window.vars[''yml_f''])'
enddef

and what about making this works

def g:Py3_SimpleMinimalTest(yml_fpath: string): void
  var yml_f:string  = yml_fpath
  exe 'py3 print(sys.version)'
  exe 'py3 print(vim.current.????.vars[''yml_f''])'
enddef

Thank you

I guess you mean that in Vim9 script and in a :def function the "let"
command doesn't work. You can just leave it out, e.g.:

w:abc3 = 'def'

You mean to pass a reference of the class and use it in Python? No,
that is not possible. The class implementation is only halfway, but
even when the work has been done a Python script will not be able to
access a Vim class directly. You can only use it in a Vim script
context, such as using "vim.eval()".
