patch 9.0.1830: Vim9: crash when accessing a null object Commit: https://github.com/vim/vim/commit/d7085a06358c22250a27186bb7d52112ed4addd1 Author: Gianmaria Bajo <mg1979.git@gmail.com> Date: Thu Aug 31 18:15:26 2023 +0200 patch 9.0.1830: Vim9: crash when accessing a null object Problem: Vim9: crash when accessing a null object Solution: Check accessing a NULL object in def function An object is NULL when the variable is declared, but the constructor isn't called. Accessing/setting a member on the object crashed Vim. Note: this happens inside def functions, at script level things work differently. Accessing a NULL object member results in E1360 (correctly), while setting a value on it results in E1012 (type mismatch) so there's still something to fix. closes: #12973 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Gianmaria Bajo <mg1979.git@gmail.com>

The ftplugin directory is for Vim plugin scripts that are only used for a
specific filetype.

All files ending in .vim in this directory and subdirectories will be sourced
by Vim when it detects the filetype that matches the name of the file or
subdirectory.
For example, these are all loaded for the "c" filetype:

	c.vim
	c_extra.vim
	c/settings.vim

Note that the "_" in "c_extra.vim" is required to separate the filetype name
from the following arbitrary name.

The filetype plugins are only loaded when the ":filetype plugin" command has
been used.

The default filetype plugin files contain settings that 95% of the users will
want to use.  They do not contain personal preferences, like the value of
'shiftwidth'.

If you want to do additional settings, or overrule the default filetype
plugin, you can create your own plugin file.  See ":help ftplugin" in Vim.
