Error in Ruby code embedded in vim9script

[Ni Va]

Hi all,

I got an error using Ruby code embedded in vim9script, seems something has changed in vim9script in this case. Like it understand $ as begin  of a range no ?

Thank you

Error detected while compiling command line..function readxml#mainruby[1]..<SNR>131_rubyCaller:

line    8:

E1050: Colon required before a range: $LOAD_PATH << Vim::evaluate('expand("$vim/extensions/ruby/lib/ruby/3.0.0")')

This is the code

vim9script

# MIT License. Copyright (c) 2021 June 02 Niva.

# Ruby code section

def readxml#mainruby()

  call s:rubyCaller() 

enddef

def s:rubyCaller()

ruby << EOF

# Core

$LOAD_PATH << Vim::evaluate('expand("$vim/extensions/ruby/lib/ruby/3.0.0")')

Your example looks like it's incomplete. Can you give a minimal example
that fails?

Yes.

This is in my _vimrc

nnoremap <F6>            :exe '!start '.expand('$vimruntime/gvim.exe').' -c "call readxml\#mainruby()"'<cr>

Under this dir  vimfiles\plugged\readxml\autoload this code is in a script called readxml.vim

vim9script

# Ruby code section

def readxml#mainruby()

  call s:rubyCaller() 

enddef

def s:rubyCaller()

ruby << EOF

# Core

$LOAD_PATH << Vim::evaluate('expand("$vim/extensions/ruby/lib/ruby/3.0.0")')

EOF

enddef

Use Case : then I type <F6>

Thank you Bram.

OK, using "ruby << EOF", aka heredoc, in a :def function is not
supported yet. You can use a legacy function for now.

bread. If they have eggs, get a dozen". The programmer comes home with 12
loafs of bread.

Ok, Can I code legacy function in a vim9script just for this case and keep all rest with def function ?

Thank you Bram
