patch 9.0.2146: text-property without type errors when joining Commit: https://github.com/vim/vim/commit/0d0b3b19517c321b089d637919e88e49a07a3d85 Author: Christian Brabandt <cb@256bit.org> Date: Sun Dec 3 17:56:43 2023 +0100 patch 9.0.2146: text-property without type errors when joining Problem: text-property without type errors when joining Solution: count all text-properties, with or without type before joining lines Error when joining lines with text properties without a proper type When joining lines, we need to consider all text properties that are attached to a line, even when those text properties are invalid and do not have a type attached to them. However, since patch v9.0.0993 (commit: 89469d157aea01513bde826b4519dd6b5fbceae4) those text properties won't be counted when joining lines and therefore this will cause the adjustment for text properties on joining to go wrong (and may later cause SIGABRT with an invalid free pointer) I am not sure, why the condition to not count text properties with a valid type was added in patch v9.0.993, because no test fails if those condition is removed. So let's just remove this condition and add a test that verifies, that we are able to join lines, even when the text properties attached to it do not have a valid type. fixes: #13609 closes: #13614 Signed-off-by: Christian Brabandt <cb@256bit.org>

Tutor is a "hands on" tutorial for new users of the Vim editor.

Most new users can get through it in less than one hour. The result
is that you can do a simple editing task using the Vim editor.

Tutor is a file that contains the tutorial lessons. You can simply
execute "vim tutor" and then follow the instructions in the lessons.
The lessons tell you to modify the file, so DON'T DO THIS ON YOUR
ORIGINAL COPY.

On Unix you can also use the "vimtutor" program.  It will make a
scratch copy of the tutor first.

I have considered adding more advanced lessons but have not found the
time. Please let me know how you like it and send any improvements you
make.

Translation
-----------

The tutor.xx and tutor.xx.utf-8 files are translated files (where xx is the
language code).  The encoding of tutor.xx might be latin1 or other traditional
encoding.  If you don't need a translation with such traditional encoding,
you just need to prepare the tutor.xx.utf-8 file.
If you need another encoding, you can also prepare a file named tutor.xx.enc
(replace enc with the actual encoding name).  You might also need to adjust the
tutor.vim file.
The "make" command can be used for creating tutor.xx from tutor.xx.utf-8.
See the Makefile for detail.  (For some languages, tutor.xx.utf-8 is created
from tutor.xx for historical reasons.)
