vim9 autoload script modified : How to reload it On-The-Fly

[N i c o l a s]

Hi,

Currently modifying an autoload/vim9fooscript.vim which can be started by typing a nnoremap as this :

• _vimrc :

import autoload './vimfiles/some/thing/autoload/vim9fooscript  .vim'
as thatHelp
nnoremap inout <ScriptCmd> thatHelp.E10_InOut()<CR>

• vimfiles/some/thing/autoload/vim9fooscript.vim  

            def Foo which is currently modifying

How to force "recompile" the new modified content of def Foo without touch the nnoremap ?

Thank you

Sourcing the autoload script should clear the old definitions and
compile the new ones. See :help vim9-reload.

Hope this helps,
Life.

There is no reliable way to reload an autoload script and have all the
changes take effect. It's best to exit Vim and restart. Trying to make
this work without a Vim restart is not only complicated, it is also
going to be unreliable.

Ok Bram that what I do each time I modify an autoload vim9script (so I do the best I can :)

effectively, sourcing does not work sorry lifepillar: it echoes to me a message E1091 Function HighCaller (below) is not compiled.

And the calling tree is as this :

nnoremap foo <ScriptCmd> Helper. HighCaller  ()<CR> ->  autoload/vim9fooscript.vim :: exported def HighCaller() ->  autoload/vim9fooscript.vim :: def SubCalled

So it seems to be  needed to add a mapping to launch gvim -c with the command test I need.

Thank you

There may be something else going on in your script, possibly a syntax
error in some function. This trivial example works for me:

~/.vim/autoload/vim9fooscript.vim

vim9script

export def HighCaller()
SubCalled()
enddef

def SubCalled()
echo 'I was called!'
enddef

~/.vim/vimrc

import autoload "vim9fooscript.vim" as Helper
nnoremap gG <Scriptcmd> Helper.HighCaller()<cr>

When I start Vim and type gG, Vim echoes 'I was called!'. If I then
change the echo message to something else, save the script and then
:source ~/.vim/autoload/vim9fooscript.vim, I get no errors and gG prints
the updated message.

Hum, thanks a lot Life, after one more check:

./vimfiles/plugged/foo-helper.vim/autoload/vim9fooscript.vim

vim9script

# some many defs func

export def  High_Caller(): void
   Sub_Called(4)
enddef  

def  Sub_Called(code: number ): void

  # some job

enddef  

~/_vimc

import autoload './vimfiles/plugged/foo-helper.vim/autoload/vim9fooscript.vim' as Helper

nnoremap io <Scriptcmd>  Helper.High_Caller()<cr>

typing io it echoes  E1091: Function is not compiled:  vim9fooscript#High_Caller

Does foo-helper.vim directory must match vim9fooscript ?

I'd start by removing the "many function defs", and possibly simplifying
the body fo Sub_Called(), and see if I can source without error. Then,
I would start to gradually re-add the removed material until I find what
is causing the error.

Hope this helps,
Life.

Found and sorry.

vim9script

if exists("g:did_load_helper")
  finish    
endif
g:did_load_helper = 1

I thought in the help for vim9 same mecanism to prevent loading script can be applied. Maybe a mistake of reading from me.

Thank you Life
