E239 triggered "invalid sign text: ~^^"

[MarkVasile]

I had to change the g:signify_sign_delete_first_line to just '-' to avoid getting E239.

@liuchengxu I confirmed that it is reproducible. It is because of this bug in Signify - https://github.com/mhinz/vim-signify/issues/366#issuecomment-773194757

I'm also getting this error:

E239: Invalid sign text: ~^^

Signs can't be more than two columns. The new g:signify_sign_change_delete has a default of g:signify_sign_change . g:signify_sign_delete_first_line, so if the combination of them is more than 2 columns, you will get the E239 error.

This is documented in signify:

                                              *g:signify_sign_add*
                                              *g:signify_sign_delete*
                                              *g:signify_sign_delete_first_line*
                                              *g:signify_sign_change*
                                              *g:signify_sign_change_delete*
>
    let g:signify_sign_add               = '+'
    let g:signify_sign_delete            = '_'
    let g:signify_sign_delete_first_line = '‾'
    let g:signify_sign_change            = '!'
    let g:signify_sign_change_delete     = g:signify_sign_change . g:signify_sign_delete_first_line
<
The sign to use if a line was added, deleted or changed or a combination of
these.

You can use Unicode characters, but signs must not take up more than two
cells. Otherwise, |E239| is thrown.

So either change g:signify_sign_delete_first_line to not be two characters, or set g:signify_sign_change_delete to a specific value.

Thanks @jamessan , that's a misuse of space-vim then, it doesn't complain about that earlier though :(.

[jamessan]

@liuchengxu You can keep g:signify_sign_delete_first_line = '^^' as long as g:signify_sign_change_delete is explicitly set to some string that is one or two columns, instead of using the default value.
