Coacher
Coacher created an issue (vim/vim#19160)Steps to reproduce
- Create
test.vimas shown below - Run
vim --clean -u test.vimvia Vim with -clipboard and without GUI - Observe compilation error on start
test.vim:
vim9script
export var register: string
export def StoreClipboardName()
if !has('clipboard')
register = ''
else
var names = split(&clipboard, ',')
if index(names, 'unnamedplus') >= 0
register = '+'
elseif index(names, 'unnamed') >= 0
register = '*'
else
register = ''
endif
endif
enddef
autocmd VimEnter * StoreClipboardName()
Expected behaviour
There is no compilation error, because the code is valid.
This behavior is observed when running vim --clean -u test.vim via Vim with +clipboard and with GUI, e.g. vimx.

Coacher left a comment (vim/vim#19160)I've tested it a bit more. Here is a minimal example that works on any build:
vim9script
def TestFunction()
if !has('bugs')
echo 'No bugs'
else
var a_variable = 0
if a_variable > 0
echo 'Positive'
elseif a_variable < 0
echo 'Negative'
else
echo 'Zero'
endif
endif
enddef
defcompile
I've replaced check for 'clipboard' feature with an obviously missing feature. The issue then can be triggered on any build. I've also replaced all calls to other functions with simple echoes and assignments.
Surprisingly, replacing !has check with false allows to compile the function.
Also removing only elseif clause allows to compile the function.
Also saving the result of !has check to a variable before the outermost if clause allows to compile the function.
