vim9 | how to force legacy vimscript execution

[Ni Va]

Hi,

I am currently using this legacy vimscript https://github.com/tweekmonster/startuptime.vim.

It is managed by Plug.vim plugins' manager in my vim9script _vimrc.

It appears startuptime.vim warns on some script code such as :

    echomsg 'Tagbar: Vim versions lower than 7.0.167 have a bug'
          \ 'that prevents this version of Tagbar from working.'
          \ 'Please use the alternate version posted on the website.'

identically warns on if brackets spread on multiple lines.

How can I fix it or fix this call of legacy vimscript ?

Thank you

NiVa

I can't find this echomsg statement in startuptime.vim as linked. I
suppose it comes from somewhere in Tagbar. Could you please tell us
what code (if statement etc.) triggers this message? (I suppose you
are using Vim 8.2 aren't you?)

Best regards,
Tony.

Hi 

This issue is general.

This is for TagBar plugin : Plug 'https://github.com/preservim/tagbar.git'

This is the code in Tagbar where the error message you previously
mentioned was produced:

if v:version == 700 && !has('patch167')
echohl WarningMsg

echomsg 'Tagbar: Vim versions lower than 7.0.167 have a bug'
\ 'that prevents this version of Tagbar from working.'
\ 'Please use the alternate version posted on the website.'

echohl None
finish
endif

It means you are using Vim 7.0 without patch 7.0.167. That version of
Vim is obsolete. Please upgrade to at least version 8.2 (the current
patchlevel as of this writing is 8.2.3877 AFAIK).

Best regards,
Tony.

It seems that the problem is in interaction between vim9script | vimscript through vimrun launch command. 

eg : my _vimrc is written in vim9script and the fact that Startuptime command (autoload part of https://github.com/tweekmonster/startuptime.vim. ) launches 

a vimrun.exe of all plugin as TagBar which is written in vimscript legacy.

resolved by porting just plugin part of this plugin in vim9script
